DESCRIPTION:A little over a decade after the first report of vibrational sp
ectroscopy in the STEM\, this informal seminar will illustrate the extreme
ly wide impact high-energy-resolution STEM-EELS has had across numerous sc
ientific fields. Beyond headline demonstrations of atomic-resolution phono
n or magnon spectroscopy\, which provide a unique tool to probe quantum ma
tter and phenomena at device-relevant length-scales\, these new instrument
s have also found cross-disciplinary applications in areas of research as
varied as cosmochemistry (with nanoscale vibrational analysis of the molec
ular constitution of extraterrestrial organic matter in returned samples f
rom JAXA’ Hayabusa2 or NASA’s OsirisREx missions)\, fundamental inorga
nic chemistry (with ‘extreme’ encapsulated nano-systems offering atomi
c-scale ‘test-tubes’ to study gas or molecular interactions a handful
of one molecules at a time) or metallurgy with new insights provided into
decades old unresolved debates\, e.g. concerning heterogeneous nucleation
in metallic alloys). With further instrumentation developments on the hori
zon such as new sample stages reaching temperatures as low as a few K\, th
ere is now truly a synchrotron in our microscopes!\nSpeaker: Prof. Quentin

DESCRIPTION:Efficient energy converters require high-performance magnetic m
aterials such as rare earth permanent magnets. Due to the criticality of r
are earth metals\, the major challenges are the reduction or avoidance of
those elements in permanent magnets and to optimize the microstructure to
approach theoretical predictions of micromagnetism. For better sustainabil
ity\, it is furthermore expected for the materials to secure long-lasting
use with subsequent recycling options. Possible solutions include: (1) In-
depth quality assessment of magnets: A good process quality is the prerequ
isite for a long magnet lifetime. Defects cause premature demagnetization
and thus aging of the magnets. Different microscopy techniques in combinat
ion with quantitative image analysis as well as component testing are deve
loped as tools for quality assurance. (2) Tailoring and optimization of ma
terials to the requirements of the electrical machine: Starting from well-
known microstructure-property relations the magnetic properties can be tai
lored from a sustainability and economic point of view. Ce-substituted mag
nets and directly recycled magnets are particularly promising. (3) Identif
ication of new materials and new technologies: Bulk high-throughput method
s allow to explore completely new hard magnetic phases. The extent to whic
h laser powder bed fusion additive manufacturing can lead to good magnetic
properties and new perspectives needs to be examined. The presentation gi
ves insight into the different solutions.\nSpeaker: Prof. Dagmar Goll

DESCRIPTION:Renewable electricity from solar photovoltaics (PV)\, combined
with low-cost large-scale storage\, is likely to play a dominating role in
decarbonizing the expanding global power sector in the long run. For exam
ple\, the global deployment of PV is targeted at ~75 TW installed capacity
by 2050\, from the current (2025) ~2.5 TW. While currently used PV techno
logies are efficient\, reliable\, and relatively cheap\, there is\, and al
ways will be\, insatiable demand for new PV technologies that are more eff
icient and cost-effective\, and importantly\, have a smaller ‘carbon-foo
tprint.’ In this context\, the promising new PV technology based on a fa
scinating class of halide-perovskite materials has the potential to meet a
ll those requirements. Perovskite thin-film PV can be mechanically rigid o
r flexible\, where the latter lightweight PV are more versatile with the p
otential to power internet-of-things\, vehicles\, satellites\, portable su
pplies\, etc.\, in addition to rooftop and utility-scale applicatio
ns. While the record power-conversion efficiency of perovskite PV now riva
ls that of conventional silicon PV\, durability and mechanical reliability
are becoming ‘bottleneck’ challenges in perovskite PV. To address som
e of these technical hurdles in the path towards their commercialization\,
we have researched several rationally-designed microstructural and interf
acial tailoring approaches. These include grain-coarsening\, grain-boundar
y functionalization\, and engineering of interfaces and substrates. Most i
mportantly\, these approaches are designed to not only enhance the PVs’
mechanical performance but also increase efficiency and improve durability
simultaneously. The scientific rationales for these approaches will be di
scussed\, together with the presentation of current results.\nSpeaker: Pro

DESCRIPTION:Recent advances in transmission electron microscopy (TEM) have
pushed spatial resolution into the 0.5 Å regime\, shifting imaging from
an instrument-limited to an object-limited discipline and enabling the di
rect visualization of individual atoms and molecules. However\, the struct
ures and dynamics of many functional materials\, particularly catalysts\,
are strongly influenced by their local environment\, creating challenges f
or imaging under conventional high‑vacuum and high‑dose conditions. In
this seminar\, two complementary developments in instrumentation and imag
ing methodology will be presented\, each expanding the capabilities of TEM
for both in‑situ and ex‑situ studies. First\, open‑cell TEM\, also
known as environmental TEM (ETEM)\, will be described. The VISION PRIME pl
atform\, built on an ultra-stable SPECTRA ETEM system\, will be introduced
. Through the integration of a 5th-order aberration corrector\, monochroma
ted illumination\, differential pumping that enables operation at 10-20
mbar gas pressure\, and direct electron detection\, a 0.5 Å information
limit is maintained even in gas atmospheres. Using Young’s fringes and
exit wave phase reconstruction\, atomic‑resolution visualization of gas
–surface interactions on a Au nanoparticle at 1 mbar N₂ has been dem
onstrated\, revealing gas-dependent variations in atomic column widths and
enabling operando studies of catalytic processes. Second\, examples of ex
it wave phase reconstruction obtained using a low dose focal series recons
truction (LD‑FSR) methodology will be presented. This approach enables 1
.6 Å‑resolution imaging of organic materials with limited radiation d
amage to the sample. By rapidly recording hundreds of low dose frames at c
ryogenic temperatures and reconstructing the exit plane wavefunction\, abe
rration-corrected phase images up to the microscope’s information limit
are obtained. In this way\, access is provided to organic crystal structur
es and aperiodic features that would otherwise be obscured under strong de
focus conditions and low signal-to-noise ratio. When combined with complem
entary methods such as density functional theory\, reliable determination
of molecular packing and local structural distortions is enabled directly
from real-space images. Finally\, a combined approach employing LD-FSR and
4D-STEM for imaging sensitive organic crystalline polymers will be demons
trated.\nSpeaker: Dr. Idan Biran

DESCRIPTION:Lithium metal solid-state batteries have high potential for saf
ety\, energy density\, and charging rate beyond that of Li-ion batteries.
A major challenge for lithium metal solid-state batteries is the formation
of lithium dendrites across the solid electrolyte during cycling\, which
leads to short-circuiting and mechanical failure of the cell. The reason t
hat dendrites form is not fully understood\, but evidence shows that dendr
ites could initiate either at the surface or within the interior of the so
lid electrolyte. Here\, I present our use of in-situ mechanical and electr
ochemical testing to investigate dendrite initiation and propagation. Scan
ning electron microscopy and optical microscopy are used to observe nano t
o millimeter-scale structural changes in garnet-type oxide solid electroly
tes (LLZO) and glassy sulfide electrolytes under mechanical loads and elec
trochemical charging. We find that dendrite propagation follows Weibull st
atistics in polycrystalline LLZO. Ag-doped LLZO shows increased resistance
to dendrites under elevated mechanical loads due to compressive stress ef
fects at the LLZO surface. Investigations on single crystal LLZO demonstra
te that the role of surface flaws in the absence of grain boundaries\, and
that Li plating can be achieved over large areas. Confocal raman spectros
copy is used to understand chemical heterogeneities within a glassy sulfid
e electrolyte control the mechanical failure. Lastly\, I present the effec
t of biaxial compressive stress on dendrite initiation and propagation in
LLZO. The biaxial compressive stress is applied orthogonal to the electric
field generation\, and serves to close cracks that extend from the anode\
, through the electrolyte\, to the cathode. This allows lithium symmetric
cells to be cycled at current densities up to 100 mA/cm2\, for >\;10\,00
0 cycles\, and provides evidence that lithium plating occurs within the in
terior of LLZO when surface dendrite initiation is suppressed.\nSpeaker: P

DESCRIPTION:Devices from thermoelectric materials can directly convert heat
flows into electrical energy powering autonomous sensors or providing rel
iable electrical power supply in remote areas\, as successfully demonstrat
ed e.g. by the Voyager space probes or the Mars rovers Curiosity and Perse
verance. On the other hand\, they can also be employed for maintenance-fre
e\, seamlessly adjustable and scalable thermal management solutions\, e.g.
for fuel cells or optoelectronic systems. To unlock further applications
of thermoelectric materials alternatives to state-of-the-art bismuth tellu
ride are required. Magnesium-based TE materials like MgAgSb\, Mg3(Sb\,Bi)2
and Mg2(Si\,Sn) are among the most promising candidates due to excellent
performance\, low cost\, and environmental compatibility. However\, functi
onal stability under application conditions is an indispensable requiremen
t\, which proves to be a significant challenge for many high- performance
materials\, Mg-based ones in particular. For those\, loss of volatile Mg a
long grain boundaries as well as demixing are the main challenges. Taking
Mg2(Si\,Sn) as example\, we’ll discuss how to derive material transforma
tion mechanisms from readily available experimental data\, compare their e
ffect on material transport properties and analyze the influence of enviro
nmental parameters (temperature\, atmosphere) on the material degradation
rate. From this understanding strategies against material instability can
be derived effectively and evaluated experimentally. Focussing on Mg loss
as the most relevant degradation mechanism we’ll discuss the following a
pproaches: i) controlling the Mg vapor pressure\, ii) fine-tuning the Mg c
ontent of the material to avoid loosely bound Mg\, iii) coating\, and iv)
grain boundary engineering to stop Mg diffusion. Employing these\, materia
l degradation is reduced by several orders of magnitude\, resulting in hig
h-performance materials with enhanced stability.\nSpeaker: Prof. Johannes

DESCRIPTION:The diversities in crystalline structure and the hierarchical f

further design\, select and assess suitable materials for a specific appli
cation. Over the last decades\, based on multi-scale understanding - from
metre to micrometre and further down to nanometre and atomic-scale\, a num

applied globally. This research work will present the alloy design\, multi

DESCRIPTION:Sintered copper (Cu) nanoparticles have emerged as a promising
substitute for sintered silver (Ag) nanoparticles in power electronics pac
kaging\, offering comparable electrical and thermal conductivities\, super
ior mechanical strength\, and lower cost. However\, the complex interactio

performance during sintering remain insufficiently understood. This resea

bility of sintered Cu nanoparticles through a combination of microscale ex
periments and multiscale modeling. The studies revealed the anisotropic fr
acture toughness of sintered Cu nanoparticles\, developed an Anand viscopl

rfacial strength while elucidating the effects of oxidation on bonding qua
lity. Furthermore\, the influence of particle morphology on mechanical pro
perties was examined using micro-cantilever bending tests and phase-field
fracture simulations. Overall\, this work advances the understanding of si

effective interconnect materials for next-generation power electronics.\nS

DESCRIPTION: Comprehensive investigations of material properties in crystal
line systems require information spanning atomistic to continuum scales. M
esoscale models play a crucial role in this context. They enable the study
of large systems and long timescales while retaining microscopic details
relevant to the targeted applications. This presentation illustrates recen
t results on key aspects of microstructure evolution in crystalline system
s obtained via newly developed mesoscale frameworks for defects and interf
aces. Using a bicrystallography-respecting continuum model that incorporat
es parameters obtained from atomistic methods\, we first discuss phenomena
associated with disconnection-mediated grain boundary (GB) motion\, such
as GB faceting and grain rotation. Then\, through a phase-field formulatio
n of this model\, we demonstrate that internal stresses generated by disco
nnection flow (shear coupling) induce significant deviations from classica
l curvature-driven grain growth in microstructures. This provides a compel
ling explanation for the lack of correlation between GB velocity and curva
ture observed in recent experiments\, identifying its primary cause. In th
e final section\, an overview of other mesoscale frameworks that build upo
n the phase-field crystal model and its coarse-graining is provided. Repre
sentative results are presented\, including the effects of temperature cyc
ling on GB motion\, as well as an emerging general framework for analyzing
defect dynamics in systems with microscopic order\, which extends beyond
conventional crystals.\nSpeaker: Prof. Marco Salvalaglio

DESCRIPTION: Topological defects—dislocations\, grain boundaries\, and re
lated features—play an essential role in determining the properties of c
rystalline materials. When crystallite or functional domain sizes shrink t
o the nanometer scale\, these defects become dominant. To date\, however\,
neither bottom‑up nor top‑down synthesis has provided a reliable mean
s of controlling them. Here\, we demonstrate delicate control over shell e
pitaxy on nanocrystals within thin films\, producing three‑dimensionally
organized nanocrystallites with uniform grain boundaries and associated d
efects. In these structures\, the resulting 3D‑patterned strain field ca
n be mapped with atomic precision and tuned to introduce targeted dislocat
ions or disclinations. Using multiscale crystallography and spectroscopy\,
we show that the uniformity and discreteness of these defects provide a c
lear correlation between local structure and collective electrochemical pe
rformance—specifically\, catalytic activity in oxygen evolution and redu
ction reactions. Finally\, we outline how this nanocrystallite‑engineeri
ng approach is guiding the design of next‑generation functional material
s for energy nanotechnology\nSpeaker: Dr. Myoung Hwan Oh

DESCRIPTION: Understanding the geometry of nanomaterials at the atomic scal
e provides critical insights into local structural heterogeneities and the
ir impact on functional properties. Since shapes vary from particle to par
ticle\, detailed analysis at the single-particle level is essential. In th
is talk\, I will present a high-throughput pipeline that integrates deep l
earning-based segmentation with quantitative shape analysis of individual
nanoparticles from high-resolution transmission electron microscopy (HRTEM
) images. First\, I will describe the application of convolutional neural
networks (CNNs) to segment 727 HRTEM micrographs of cubic Co3O<
sub>4 nanoparticles\, enabling the extraction of shape descriptors f
rom 441\,067 particles. This automated workflow allows for population-wide
statistical characterization\, bridging local structural detail with larg
e-scale analysis. Second\, I will present a size-resolved shape analysis a
t subnanometer precision\, highlighting a critical threshold\, “onset ra
dius”\, that marks transitions in particle shape\, such as surface facet
ing and a shift from thermodynamic to kinetic growth regimes. This bottom-
up approach illustrates how machine learning and data-driven analysis can
reveal previously unquantified trends\, offering a generalizable framework
for high-throughput materials characterization.\nSpeaker: Dr. Min Gee Cho

DESCRIPTION: Recent groundbreaking developments in aberration-corrected sca
nning transmission electron microscopy (STEM) combined with advanced vibra
tional electron energy-loss spectroscopy (EELS) techniques have fundamenta
lly transformed the way atomic-scale lattice dynamics and phonon behaviors
are studied. In this seminar\, I will highlight our seminal work in devel
oping and applying state-of-the-art\, spatially and momentum-resolved vibr
ational EELS methodologies to directly visualize phonon modes at atomic re
solution. Our approach enables the unprecedented observation of localized
phonon phenomena at individual defects\, interfaces\, and nanostructures\,
profoundly advancing our understanding of phonon-defect interactions\, th
ermal boundary conductance\, and electron–phonon coupling in materials.
I will present key examples from our recent studies\, including the direct
imaging of defect-localized vibrational modes\, nanoscale mapping of inte
rfacial phonons\, and quantification of phonon momentum distributions in q
uantum dots and phonon-electron coupling at superconducting interfaces. Th
ese insights provide critical foundations for addressing fundamental chall
enges in thermal management\, quantum materials engineering\, and solid-st

DESCRIPTION: Microstructures in many engineering alloys are predominantly i
nfluenced by solid-state phase transformations that occur during industria
l processing\; these transformations almost always proceed by nucleation a
nd growth. Quantitative modelling of the process often requires detailed k
nowledge of the interfaces\, notably the interfacial energies that determi
ne nucleation barriers and the interfacial mobilities that control growth
kinetics—both of which depend sensitively on the the interfacial structu
res. Beyond their role in transformation kinetics\, interfacial structures
and the accompanying orientation relationships (ORs) and interface orient
ations (IOs) are microstructural features in their own right and directly
influence bulk properties. Based on extensive studies of diverse alloy sys
tems\, we have formulated a unified framework that rationalises the prefer
red interfaces and their reproducible ORs produced by phase transformation
s\, by employing preferred interfacial structures of two hierarchical leve
ls. At the fine (atomic) level\, the interface adopts a low-energy\, perio
dically matched configuration that minimises the nucleation barrier. Such
matching is possible only for specific intrinsic ORs and IOs\, thereby imp
osing the geometric constraints. The structures of the coarse level are ch
aracterized by singular interfacial defects. Their development\, preferred
under given phase transformation conditions\, allows the OR and IO to dev
iate within certain limits from the intrinsic values. This talk will prese
nt general methods for correlating ORs and IOs with interfacial structures
at both levels and will illustrate the approach with examples from severa
l material systems\nSpeaker: Prof Wen-Zheng Zhang

DESCRIPTION: Recent studies have shown that the passage of an electric curr
ent pulse may both propagate [1\,2] and close a crack and heal a metallic
material [3]. Specifically\, experiments on thin Al foils containing edge
cracks have proved that the self-induced electromagnetic forces\, spontane
ously generated upon passage of an electric current across a crack in a sa
mple\, alone could cause crack propagation without melting of the crack ti
p [1]. The critical current density required for crack propagation reduces
in the presence of an external magnetic field [4] as well as mechanical l
oad [5]. On the other hand\, if an electric current pulse of large pulse w
idth is passed through an electrically and thermally resistive material\,
such as stainless steel\, containing a short crack\, the crack may complet
ely close\, and the material can heal through the solid-state diffusion bo
nding process [3]. Here\, we discuss the reasons behind crack propagation
upon application of electric current and then explore the mechanics as wel
l as microstructural attributes responsible for a transition from flaw pro
pagation to flaw healing upon passage of an electric current pulse. Furthe
rmore\, the recovery of the mechanical properties of the material upon ele
ctric current-induced healing will also be discussed.\nSpeaker: Prof. Prav

DESCRIPTION: Defects and Grain boundaries have a remarkable effect on the t
hermal and electrical transport properties of polycrystalline materials bu
t are often ignored by prevailing physical theories. The concentration of
point defects can be altered with phase boundary mapping considering the d
efect thermodynamics. Thus\, the properties can be engineered with careful
processing control. Grain boundaries and interfaces can adversely alter t
he thermal and electrical properties of Power Electronics\, Solar Cells\,
Batteries\, Thermoelectrics and permanent magnets such as interfacial elec
trical and thermal resistance (Kapitza resistance). Interfacial thermal re
sistance limits the performance of power electronics because of overheatin
g. New scanning thermal reflectance techniques can image the thermal resis
tance of interfaces and boundaries directly. The Thermal conductivity supp
ression at grain boundaries can even be imaged showing that different grai
n boundaries can have very different thermal resistances with high energy
grain boundaries having more resistance and low energy boundaries having l
ower thermal resistance. Interfaces and grain boundaries are 2-dimensional
thermodynamic phases (complexions) that have distinct energy\, compositio
n and properties that can be rigorously described using the Gibbs excess f
ormalism. The common thermodynamic quantities of temperature and chemical
potential connects the complexions to the 3-D phases allowing a phase boun
dary mapping of grain boundary and interface properties similar to that fo
r point defects.\nSpeaker: Prof. Jeff Snyder

DESCRIPTION: Two-dimensional (2D) materials\, such as Graphene\, hBN\, and
MoS2\, are promising candidates in a number of advanced functio
nal and structural applications owing to their exceptional electrical\, th
ermal\, and mechanical properties. Understanding the mechanical properties
of 2D materials is critically important for their reliable integration in
to future electronic\, composite\, and energy storage applications. In thi
s talk\, we will report our efforts to study the fracture behaviors of 2D
materials. Our combined experiment and modelling efforts verify the applic
ability of the classic Griffith theory of brittle fracture to graphene [1]
. Strategies on how to improve the fracture resistance in graphene\, inclu
ding a nanocomposite approach\, and the implications of the effects of def
ects on mechanical properties of other 2D atomic layers will be discussed
[2\, 3]. More interestingly\, stable crack propagation in monolayer 2D
h-BN is observed and the corresponding crack resistance curve is obtai
ned for the first time in 2D crystals [4]. Inspired by the asymmetric latt
ice structure of h-BN\, an intrinsic toughening mechanism without l
oss of high strength is validated based on theoretical efforts\, enabling
stable crack propagation not seen in graphene. Finally\, we will also disc
uss some of our recent efforts in evaluating the mechanical properties of
2D covalent organic frameworks (COFs) [5\, 6] and the fracture behaviors o

y more. Thus failure due to hydrogen embrittlement is not present at high
temperatures. At low temperatures the diffusion of hydrogen to defect gene
rated by deformation will be reduced and\, therefore\, the decrease of def

DESCRIPTION:Abstract: Some of the most pressing challenges in engineering s
cience arise when materials are adjacent to one another - from the bottom
of an impacting droplet to the separating faces of a crack. Here I will di
scuss two vignettes on these important topics: first\, a calibrated\, nano
-scale\, direct measurement of the intervening air film at the critical ju
ncture of contact formation during droplet impact\, and second\, the tough
ening that can result from geometric complexity at the tip of a propagatin
g crack. These seemingly disparate systems are deeply connected on a varie
ty of levels\, from their sensitivity to defects to the propagating singul
arity that defines the mathematical problem of contact line and crack prop
agation. The talk will conclude with a discussion of perspectives and some
puzzles that remain open despite recent progress.\nSpeaker: Prof. John Ko

DESCRIPTION: Solid-state batteries (SSBs) promise to meet the increasing de
mand for safe\, high-power\, and high-capacity energy storage. SSBs with s
olid electrolytes (SEs) offer potential advantages over conventional lithi
um-ion batteries with liquid electrolytes. Their performance\, however\, s
trongly depends on the structure and composition of the various interfaces
contained in the different materials\, which also change upon electrochem
ical cycling. We use Scanning transmission electron microscopy (STEM)\, to
quantify properties of interfaces in battery materials. When compared to
image simulations\, the information on the sample structure and compositio
n derived from STEM data can be quantitative. Combining STEM with a fast\,
pixelated detector allows for the acquisition of a full diffraction patte
rn at each scan point. From this\, four-dimensional STEM (4D-STEM) dataset
s are available\, which can be used to generate different data\, e.g. annu
lar dark field (ADF) as well as (annular) bright field ((A)BF) images\, an
gular resolved STEM (ARSTEM) or differential phase contrast (DPC) data. Wi
th the example of cathode\, anode and different SE materials for battery a
pplications (e.g.\, NCM\, Si\, LLZO\, LATP)\, we track the formation of di
fferent phases of and defects within the materials in dependence on synthe
sis as well as cycling conditions of the material and derive ABF as well a
s BF images from 4D datasets. These are used to also obtain difference ima
ges (ABF-BF). It will be shown that the composition of the materials and e
specially the Lithium content can be derived from the contrast of the diff
erent atomic columns in the structure. This is possible by comparing the e
xperimental data sets to state of the art multi-slice simulations. This co
ntribution will summarize the material science aspects of the energy mater
ials investigated but also elucidate the potential of quantitative 4D-STEM
to investigate materials.\nSpeaker: Prof. Dr. Kerstin Volz

DESCRIPTION: Half-Heusler compounds exhibit significant potential in thermo
electric applications for power generation up to 1000 K\, notwithstanding
the substantial challenges posed by the cost of constituent elements and t
he imperative to augment the average thermoelectric figure-of-merit (zT
ave) for more practical applications. Overcoming these obst
acles demands the advancement of high-performance p-type TaFeSb the
rmoelectric materials with diminished Ta content. This investigation syste
matically explores the quaternary-phase space encompassing Ta\, Nb\, V\, a
nd Ti to ascertain an optimal composition\, namely Ta0.42Nb0.3V0.15Ti0.13FeSb. This composition is chara
cterized by a remarkable reduction in Ta concentration coupled with an enh
ancement in zT\, peaking at 1.23 at 973 K. Moreover\, the integrati
on of a high-mobility secondary phase\, InSb\, fosters enhancements in bot
h the Seebeck coefficient and electrical conductivity\, resulting in a 23%
augmentation in the average power factor\, while concurrently suppressing
lattice thermal conductivity. The optimized composite\, Ta0.42
Nb0.3V0.15Ti0.13FeSb-(InSb)0.015\, achieves a peak zT value of 1.43 at 973 K and a zT
ave of 1 from 300 K to 973 K\, thereby setting a precedent among
p-type half-Heusler materials. Additionally\, a single-leg device demo
nstrates a peak efficiency of approximately 8% under a temperature differe
nce of 823 K vs. 303 K. These findings underscore the substantial potentia
l of the proposed material design and fabrication methodologies in fosteri

DESCRIPTION: Thermoelectric materials can realize waste heat recovery and s
olid-state refrigeration\, providing sustainable solutions to the energy c
risis and environmental pollution. The performance of thermoelectric mater
ials is gauged by the transport of electrons and phonons. Materials with f
ast electron movement but slow phonon propagation would be ideal thermoele
ctrics. These transport behaviors of carriers are influenced by the intrin
sic chemical bonding mechanism and structural defects of materials. Unders
tanding the bonding and microstructures of materials is of paramount impor
tance to improve their thermoelectric properties. Atom probe tomography (A
PT) provides a unique combination of characterizing chemical bonding and l
attice defects\, being a very powerful tool in the study of thermoelectric
materials. It has been revealed that many of the high-performance thermoe
lectric chalcogenides utilize metavalent bonding (MVB)\, which can be dist
inguished from other bonding mechanisms by the unconventionally high value
(>\;60%) of “probability of multiple events (PME)” measured by APT.
Thus\, many new compounds with high thermoelectric performance can be des
igned by tailoring their chemical bonds\, and APT is an indispensable tech
nique to corroborate the bonding transition. Owing to the high spatial and
chemical resolution of APT\, the local change of chemical bonding at defe
cts such as grain boundaries and precipitates can also be detected by APT.
This enables us to better understand the role of chemical bonding in regu
lating the electron and phonon transport across individual defects. The re
sults in turn provide insights into the tailoring of thermoelectric proper
ties by manipulating the local chemical bonds. For example\, the thermoele
ctric properties of polycrystalline SnSe have been significantly improved
by removing the stiff Sn-O bonds at the grain boundary as directly observe
d by APT. In contrast\, the strong bonding connection between thermoelectr
ic and interfacial materials enables a high-efficiency and durable thermoe
lectric device. Based on APT\, in conjunction with other characterization
techniques\, we can explore some uncharted territories in the design of th
ermoelectric materials.\nSpeaker: Yuan Yu

DESCRIPTION: Defects and Grain boundaries have a remarkable effect on the t
hermal and electrical transport properties of polycrystalline materials bu
t are often ignored by prevailing physical theories. Grain boundaries and
interfaces can adversely alter the properties of Power Electronics\, Solar
Cells\, Batteries and Thermoelectrics such as interfacial electrical and
thermal resistance (Kapitza resistance) and even an interfacial Seebeck ef
fect. Interfacial thermal resistance limits the performance of power elect
ronics because of overheating. New scanning thermal reflectance techniques
can image the thermal resistance of interfaces and boundaries directly. T
he Thermal conductivity suppression at grain boundaries can even be imaged
showing that different grain boundaries can have very different thermal r
esistances with high energy grain boundaries having more resistance and lo
w energy boundaries having lower thermal resistance. Electrical grain boun
dary resistance can be so high in some thermoelectric materials it is the
dominant property that limits zT. While small grains are usually considere
d beneficial for thermoelectric performance due to reduced thermal conduct
ivity\, Mg₃Sb₂ based thermoelectric materials\, so far at least\, cont
radict that trend. Indeed\, atomic segregation has been recently observed
at the nanometer scale in grain boundaries in many materials suggesting in
terfacial or complexion phases should be specifically considered when unde
rstanding nearly all thermoelectric materials. The concentration of point
defects\, such as vacancies\, interstitial and substitutional atoms can no
w be predicted with DFT allowing defects to be included in phase diagram a
nalysis for prediction of materials processing for particular properties.\

DESCRIPTION: In recent decades\, extensive efforts have been done to develo
p new and more efficient alternative energy sources\, which can substitute
conventional sources like gas\, petrol\, and carbon\, have been made. Due
to the increase in energy consumed by society\, we not only need an alter
native to conventional energy sources\, but also a reduction in energy con
sumption. Therefore\, it is necessary to investigate different methods for
energy-recovery and energy-saving as such as thermoelectric materials and
radiative coolers. The thermoelectric materials can convert heat into ele
ctricity and vice versa. The efficiency of these materials is relat
ed to the figure of merit (zT) and it is defined as zT=(
σ·S2/k)·T\, where σ is the
electrical conductivity\, S is the Seebeck coefficient\, k i
s the thermal conductivity\, and T is the absolute temperature. Now
adays\, the application of inexpensive and scalable materials in the indus
try for thermoelectric applications has received great interest. In this s
ense electrodeposition is one of the most interesting techniques. It is pe
rformed at room temperature\, so it is compatible with polymeric substrate
s\, it does not require vacuum conditions\, and it allows perfect control
over the composition\, morphology\, and crystallographic structure. In thi
s presentation\, I will provide an overview of different thermoelectric ma
terials such as Bi2Te31\, CuNi2\, and Ag2Se3 grown by electrodeposition and their
thermoelectric properties. In the case of silver selenide\, a thermoelectr
ic power generator was produced and characterized. Radiative cooling is th
e process by which temperature decreases due to an excess of emitted radia
tion above absorber radiation. To achieve cooling\, it is necessary to red
uce and keep the temperature below the ambient air temperature. The requir
ements of radiative coolers to have maximum cooling power\, to be able to
reduce the temperature sufficiently\, and to function 24 hours a day anywh
ere\, are high solar reflectance and high infrared emittance\, close to th
e atmosphere’s window (between 8 and 13μm wavelengths). Different appro
aches have been explored and porous nanostructures have shown the best res
ults to this respect. In this sense\, porous anodic aluminium oxide (AAO)
nanostructures on Al was demonstrated to be a great candidate4.
AAO is an amorphous material with an isotropic permittivity\, a strong ac
oustic resonance absorption at the far IR (15 – 25 µm)\, and high trans
parency in the UV‑Vis‑NIR range. In this presentation\, I will highlig
ht the possibilities to use AAO nanostructure as radiative cooling. In add
ition\, strcutural cellulose will be also analysed for the same purpose.\n

DESCRIPTION:Due to its high diffusivity hydrogen atoms alloy with metals ev
en at room temperature. At this temperature\, the materials microstructure
remains rather stable. When the system size is reduced to the nano-scale\
, microstructural defects as well as mechanical stress significantly affec
t the thermodynamics and kinetics properties of the system.[1-6] Effects w
ill be demonstrated on Niobium-H and Palladium-H thin films.Hydrogen absor
ption in metal systems commonly leads to lattice expansion. The lateral ex
pansion is hindered when the metal adheres to a rigid substrate\, as for t
hin films. Consequently\, high mechanical stresses arise upon hydrogen upt
ake. In theory\, these stresses can reach about -10 GPa for 1 H/M. Usually
\, metals cannot yield such high stresses and deform plastically. Thereby\
, maximum compressive mechanical stress of -2 to -3 GPa is commonly measur
ed for 100 nm Nb thin films adhered to Sapphire substrates. It will be sho
wn that phase transformations change in the coherency state upon film thic
kness reduction. The coherency state affects the nucleation and growth beh
aviour of the hydride phase as well as the kinetics of the phase transform
ation.[1] It will be further demonstrated that plastic deformation can be
hindered and even suppressed upon film thickness reduction. In this case t
he system behaves purely elastic and ultra-high stress of about -10 GPa ca
n be experimentally reached.[2] These high mechanical stresses result in c
hanges of the materials thermodynamics. In the case of Nb-H thin films of
less than 8 nm thickness\, the common phase transformation from the α-pha
se solid solution to the hydride phase is completely suppressed\, at 300 K

rint is one of the lowest (2 kg of CO2 per kg of primary steel\
, and 0.7 kg of CO2 when recycled). In contrast\, the productio
n of platinum\, crucial element for hydrogen economy with a limited produc
tion of 200 t/y\, is one of the most carbon-intensive (60 tons of CO2
per kg of Pt). Limiting the challenge of the Green and digital revo
lutions to the simple cost-performance paradigm would be somehow repeating
the mistake of the Oil Age during which the resource was considered as in
finite and the impact on the environment had been long time neglected. Mak
ing the twin transition successful requires changing the mindset of innova
tors (from lower TRL) to a binary trade-off (price-performance) towards mu
lti-criteria decision-making [3]. In the presentation\, we will introduce
a straightforward multi-criteria assessment methodology for evaluating the
sustainability of metallic alloys.\nSpeaker: Dr. Janez Zavašnik

DESCRIPTION: The use of nanoindentation-based techniques to study high stra
in rate deformation behavior of materials is of immense scientific interes
t because it enables investigating the strain rate dependence of individua
l grains and small-scale structures. While nanoindentation impact tests\,
capable of reaching high strain rates\, have been used for over two decade
s\, they suffer from lack of indentation profile control and rapidly varyi
ng strain rate during impact. This makes extraction of reliable mechanical
properties\, for e.g. hardness\, and determination of the representative
strain rate rather difficult. It is only recently that advances in nanoind
entation instrumentation have enabled reaching constant strain rates >\;
100 s-1 in both micropillar compression [1] and indentation [2
]. In this talk\, I will present our progress in performing controlled\, c
onstant strain rate nanoindentation tests up to 104 s-1 for reliable extraction of mechanical properties and deformation activ
ation parameters\, particularly at high strain rates. Typically\, high spe
eds and fast unloading rates excite the resonance of the nanoindenter\, wh
ich affects the extracted hardness and modulus values. Novel experimental
protocols and calibration procedures were developed to circumvent this iss
ue\, which will be discussed. Case studies of high strain rate nanoindenta
tion testing on multiple material systems – single and ultrafine grained
metals\, amorphous glasses and polymers – will be presented. Deformatio
n activation parameters\, for e.g. activation volumes and strain rate sens
itivity exponents\, were successfully extracted at high strain rates to pr
obe possible changes in the underlying deformation mechanism(s). It is hop
ed that this study will pave the way for routine high strain rate nanoinde
ntation testing.\nSpeaker: Prof. Gaurav Mohanty

DESCRIPTION: Nanoscale metal-graphene nanolayered composites are known to h
ave ultra-high strength due to the ability of graphene to effectively bloc
k dislocations from penetrating through the metal-graphene interface. The
same graphene interface can deflect generated cracks\, thereby serving as
a toughening mechanism. In this talk\, the role of graphene interfaces in
strengthening and toughening the Cu-graphene nanolayered composite will be
discussed. In-situ TEM tensile testing of Cu-graphene showed that the dis
location plasticity was strongly confined by the graphene interfaces and t
he grain boundaries. The weak interfacial bonding between Cu-graphene indu
ced an interesting stress decoupling effect\, which resulted in independen
t deformation of each Cu layer. MD simulations confirmed such independent
deformation of each Cu layer and also showed that the graphene interfaces
effectively block crack propagation as delamination occurs at the Cu- grap
hene interfaces to allow for elastic strain energy dissipation. Bending fa
tigue testing was also conducted on Cu-graphene nanolayered composites tha
t indicated ~5 times enhancement in robustness against fatigue-induced dam
age in comparison to the conventional Cu only thin film. Such an enhanceme
nt in reliability under cyclic bending was found to be due to the ability
of the graphene interface to stop fatigue-induced crack propagations throu
gh thickness of the thin film\, which is contrary to how a metal only thin
film fails under cyclic loadings.\nSpeaker: Prof Seung Min Jane Han

DESCRIPTION: In the search for new energy sources\, nuclear fusion of deute
rium and tritium is one of the most promising options for human kind. Howe
ver\, thermonuclear fusion has set an enormous challenge to theory\, exper
iment and technology due to the harsh environment that will take place in
a future nuclear fusion reactor: 14 MeV neutron irradiation\, helium accum
ulation and hydrogen isotope (HI) implantation\, taking place at the same
time and mutually influencing each other. Tritium self-sufficiency is one
of the major prerequisites. For this reason\, a macroscopic understanding
of the phenomena involved is needed in order to predict transport and rete
ntion of fuel in future devices. I will give an overview on the knowledge
gained so far for tungsten\, the material chosen because of its good therm
al conductivity\, high melting point\, low sputtering yield and low HI ret
ention. I will show how laboratory studies addressing the synergism betwee
n displacement damage creation and presence of HIs [1-3] help in understan
ding the phenomena and to what extent they can be used to extrapolate to a
future fusion reactor. I will also present new developments of ion beam t
echniques in order to study lattice disorder and position of trapped deute
rium in the tungsten lattice.\nSpeaker: Dr. Sabina Markelj

DESCRIPTION: Development of innovative characterization tools is of paramou
nt importance to advance the frontiers of science and technology in nearly
all areas of research. In order to overcome the limitations of individual
techniques\, correlative microscopy has been recognized as a powerful app
roach to obtain complementary information about the investigated materials
. High-resolution imaging techniques such as Transmission Electron Microsc
opy (TEM) or Helium Ion Microscopy (HIM) offer excellent spatial resolutio
n. However\, the analytical techniques associated with TEM such as Energy
Dispersive X-ray spectroscopy (EDX) or Electron Energy-Loss Spectroscopy (
EELS) are inadequate for the analysis of (i) isotopes\, (ii) trace concent
rations (<\; 0.1 at. % or <\; 1000 ppm) and (iii) light elements (H\,
Li\, B). Secondary Ion Mass Spectrometry (SIMS)\, on the other hand\, has
several advantages such as the possibility to analyse elements and isotope
s of all elements of the periodic table while also providing high-sensitiv
ity to detect even trace concentrations. However\, the main drawbacks of S
IMS are (i) difficulty in quantification and (ii) lateral resolution of SI
MS imaging is fundamentally limited by ion-solid interaction volume to ~10
nm. Owing to the complementary strengths of SIMS imaging\, we developed n
ew in-situ and operando instrumentations for correlative microscopy combin
ing electron microscopy and SIMS imaging. In this presentation\, we will d
iscuss the instrumentation development aspects of correlative microscopy t
echniques based on SIMS imaging. With a range of examples from energy mate
rials\, we will show the powerful correlative microscopy possibilities tha
t emerge due to these new in-situ and operando methods and compare with ex
-situ correlation. Our recent work in the application of these methods in
hydrogen containing materials and Li ion batteries will be reviewed.\nSpea

DESCRIPTION:Our aim is to understand processes that lead to the emergence o
f catalytic function though direct observation using a combination of oper
ando scanning and transmission electron microscopy. Starting with simple m
odel catalysts\, such as polycrystalline metal foils\, we observe the prop
agation of chemical waves and reveal how catalytic activity depends on gra
in orientation\, coupling mechanisms and reaction conditions. In the case
of redox-reactions on non-noble metals\, we find that the active catalyst
is operating near a phase-boundary where metallic and oxidized phases co-e
xist. Real-time imaging reveals fascinating oscillatory redox dynamics tha
t increase in complexity with increasing chemical potential of the gas-pha
se. When moving from simple model catalysts to industrially relevant metal
nanoparticles supported on reducible oxide carriers\, we apply in-situ tr
ansmission electron microscopy to study effects related to a strong metal-
support interaction (SMSI) under reactive conditions. Using the archetypic
al titania supported platinum nanoparticles as a reference system\, and hy
drogen oxidation as model redox reaction\, it will be shown that the well-
described encapsulated state of platinum particles is lost as soon as the
system is exposed to a redox-active environment. Structural incoherence at
the platinum-titania interface lowers the barrier for redox processes\, w
hich give rise to dynamic reconstructions and particle migration. The part
icle orientation on the support determines the structure of the interface
and the resulting particle dynamics\, migration\, and sintering behaviour.
The aim of the presentation is to demonstrate that active catalysts are d
ynamically adapting to the reaction environment and that catalytic functio
n is related to the catalysts ability to participate in the reaction throu
gh reversible changes in its structure and/or (local) composition.\nSpeake

DESCRIPTION: Many of the functional materials we hope to leverage for next-
generation technological applications — such as computing\, energy harve
sting and storage\, or communication devices — draw their unique and som
etimes exotic properties from a suite of interactions between the atoms\,
spins\, and charges in a crystalline lattice. With direct\, real-space acc
ess to these order parameters down to the atomic scale\, the scanning tran
smission electron microscope (STEM) is a powerful tool to probe the fundam
ental framework of such compounds and their properties. As an example of t
his\, I will show how advanced STEM techniques can elucidate key questions
about the landscape of superconductivity in recently discovered nickelate
s. But many of these functional systems are most useful (and therefore int
eresting) away from the ambient conditions of most typical high-resolution
STEM experiments\, for instance at cryogenic or elevated temperatures or
under an external bias. It is therefore imperative to expand the environme
ntal compatibility of these methods through the parallel development of bo
th hardware and data processing tools\, key examples of which will be high
lighted here.\nSpeaker: Dr. Berit Goodge

DESCRIPTION: The persistent demand for green\, strong and ductile advanced
high strength steels\, with a reduced climate footprint\, calls for novel
and improved multi-phase microstructures. The development of these new ste
els requires an in-depth understanding of the governing plasticity mechani
sms at the micron scale. In order to address this challenge\, novel numeri
cal-experimental methods are called for that account for the discreteness\
, statistics and the intrinsic role of interfaces. This lecture sheds ligh
t on recent and innovative developments unravelling metal plasticity at th
e micron scale. Multi-phase through-thickness samples allow for a full cha
racterization of the underlying microstructure. Using computational crysta
llographic insights\, a slip system based local identification method has
been developed\, which provides full-field crystallographic slip system ac
tivity maps. The resulting deformation maps are directly used to assess th
e model predictions. Heterogeneous spatial variations are introduced by sa
mpling the slip system properties of individual atomic slip planes from a
probability density function. This allows to recover naturally localized s
lip patterns with a high resolution. It is demonstrated that this discrete
slip plane model adequately replicates the diversity of active slip syste
ms in the corresponding experiment\, which cannot be achieved with standar
d crystal plasticity models. Recent experimental observations on dual-phas
e steels demonstrate substructure boundary sliding parallel to the habit p
lane in lath martensite\, for which a habit-plane slip enriched laminate m
odel is developed. This model adequately captures the role of the substruc
ture boundary sliding on the deformation of the martensite aggregate.\nSpe

DESCRIPTION: Atom probe tomography is a powerful technique that has a long
history in Material Science applications\, however\, it has only recently
been applied to geological and extraterrestrial materials. In this talk I
will present the work we have been conducting using atom probe tomography
to date some of the oldest minerals in the Solar System and determine how
space weathering could provide a new reservoir of water on the Surfaces of
airless worlds.\nSpeaker: Dr. Luke Daly\, University of Glasgow\, Scotlan

DESCRIPTION:There’s plenty of room at the grain boundary (GB)\, in which
we can manipulate its energy and structure for particular properties in po
lycrystalline materials. Recently\, we observed that the aesthetic of the
room quantified by the electrical conductance was changed dramatically by
simply by turning on/off a UV laser. Specifically\, based on photoelectron
spectroscopy and complementary conductive atomic force microscopy\, we de
monstrate that the hundredfold increases in the electrical conductance mea
sured at the GB are strongly associated with the ultraviolet-induced oxyge
n vacancies\, and thus offering novel strategies for optoelectronic or neu
romorphic computing applications. Historically\, it is a challenge to opti
mize the room especially in the case of body-centered cubic (bcc) metals d
ue to the lack of quantitative relations between GB energies and populatio
ns or microstructure-property-processing relationships. Here\, we present
a universal function for computing the energies of arbitrary GBs in the bc
c metals. The effectiveness of the universal function in describing the va
riations of the GB energies is demonstrated by consistency between the out
put of the function and the energies of ~ 2\,500 GBs simulated by the embe
dded atom method. Large-scale comparisons between the interpolated energie
s and measured GB populations reveal that the population distributions are
governed by local energy minima located at the Σ1\, Σ3\, Σ9\, Σ11\, a
nd Σ33a misorientations\, representing a major step forward for the GB en
gineering of bcc metals.\nSpeaker: Dr. Sutatch Ratanaphan

DESCRIPTION:Steel is of enduring importance in our society. It has enabled
technological progress sustaining human civilization over millennia throug
h structural and functional applications\, even under the harshest environ
mental conditions. However\, its production requires huge energy input and
emits gigantic amounts of greenhouse gases\, qualifying it as the main dr
iver of global warming. To tackle the urgent decarbonization challenges in
the steel industry\, innovative and disruptive technologies must be inven
ted and matured\, based on solid understanding of the underlying principle
s. GreenSteel2022 presents the latest results from basic research\, innova
tive ideas\, and disruptive technologies to support the sustainable produc
tion of green steel\, highlighting the nexus among physical metallurgy\, p
rocess metallurgy\, and the coming hydrogen age. The focus is placed on th
e basic physical and chemical foundations for improving the sustainability
of steel in several areas\, including the CO2-lean primary production\, l
ow-energy metallurgical synthesis and recycling\, and applications of iron
and steel for green energy generation and transportation. We cordially we
lcome you to participate in the workshop and discussion! Please register y
our participation on our GreenSteel2022 webpage. The registration deadline
is the 5th of September.

DESCRIPTION: (zoom lecture link comes shortly before)Liquid phase ex
foliation has been proved to be a cheap\, scalable method for the mass pro
duction of 2D sheets. This talk will first discuss the galaxy of existent
layered materials\, with emphasis on synthesis\, liquid-phase exfoliation\
, and characterization\, focussing on some key applications recently devel
oped in our laboratories\, ranging from energy storage to printed electron
ics. We will for example discuss how two-dimensional Ti3C2 (MXene) can be
formulated in aqueous and organic viscous inks for extrusion printing and
inkjet printing\, respectively\, and demonstrate direct MXene printing on
various substrates. The additive- and binary solvent-free MXene inks do no
t show coffee ring effect\, enabling high-resolution printing without subs
trate pre-treatment. The resulting all-MXene printed micro-supercapacitors
showcase excellent charge storage performance\, including areal capacitan
ce up to 43 mF/cm2 and volumetric capacitance up to 562 F/cm3 in protic ge
l electrolyte\, coupled with long lifetime and good flexibility. We also s
how examples of all-inkjet-printed MXene arrays for ohmic resistors. The v
ersatile direct-ink-printing technique highlights the promise of MXene fun
ctional inks for scalable fabrication of easy-to-integrate components of p
rintable electronics. We will also discuss how MXenes can be used as a con
ductive binder for silicon electrodes produced by a simple and scalable sl
urry-casting technique without the need of any other additives. The nanosh
eets form a continuous metallic network\, enable fast charge transport and
provide good mechanical reinforcement for the thick electrode (up to 450
µm). Consequently\, record high areal capacity anodes (up to 23.3 mA
h cm−2) can be demonstrated. EMI shielding applications will also be dis
cussed.\nSpeaker: Professor Valeria Nicolosi

DESCRIPTION: Electrochemistry will play a pivotal role in our transition aw
ay from fossil fuels to a net zero society. While batteries and fuel cells
are set to decarbonise transportation\, electrolysers can enable the sust
ainable synthesis of our most coveted chemicals\, such as H2 an
d NH3. It turns out that some of the reactions that we aim to a
ccelerate in water electrolysis\, such as H2 evolution\, are ex
actly the reactions that we wish to inhibit in Li ion batteries and during
N2 reduction. To that end\, in our group we translate techniqu
es and insight from battery science to electrosynthesis and vice versa. I
will present our mechanistic studies on the electrocatalysis of (i) O
2 evolution for water electrolysis on iridium based and nickel based
oxides1 and (ii) N2 reduction to NH3 on
Li-based electrodes in organic electrolytes2\,3 and (iii) paras
itic gas evolution in Li ion batteries. Our studies incorporate electroche
mical measurements\, electrochemical mass spectrometry\, operando optical
spectroscopy\, secondary ion mass spectrometry\, x-ray photoelectron spect
roscopy and density functional theory\; using the combination of these tec
hniques\, we build a holistic picture of the factors controlling these tec
hnologically critical reactions. 1 Francas\, L.\, Corby\, S.\, Selim\, S.\

DESCRIPTION:(zoom lecture link comes shortly before) An ever-increas
ing demand for better batteries (with high voltage\, high capacity\, fast
charging\, and high safety) has set extraordinarily high standards for ele
ctrolyte materials\, which are far beyond the realm of conventional nonaqu
eous electrolyte design based on 1 mol L-1 (M) LiPF<
sub>6 and ethylene carbonate (EC). Generally\, further increasing sa
lt concentration over the conventional 1 M increases the viscosity and dec
reases the ionic conductivity\, both of which are unfavorable for battery
electrolytes in terms of reaction kinetics. However\, various unusual func
tions have been recently discovered at high salt concentrations (over 3 M)
(Fig. 1)\, including i) high reduction stability\, ii) high oxidation sta
bility\, iii) fast electrode reactions\, iv) high safety\, v) wide liquidu
s temperature range\, and vi) prevention of Al corrosion at high potential
s\, etc. As a result\, concentrated nonaqueous and aqueous solutions are e
merging as a new class of liquid electrolytes for advanced batteries. In t
his talk\, I will introduce various unusual functions of concentrated elec
trolytes\, which are not shared by conventional dilute electrolytes\, disc
uss the mechanism from the viewpoint of their unique ion-solvent coordinat
ion structures\, and present new electrolyte design strategies to advanced
batteries. Reference 1. Y. Yamada et al.\, Nat. Energy\, 4\, 269 (

DESCRIPTION:(zoom lecture link comes shortly before) Current state-o
f-the-art lithium-ion batteries (LIBs) contain electrode materials with mo
stly layered structures that serve as host lattices for the reversible\, e
lectrochemical intercalation of lithium ions. The kinetics of these interc
alation reactions are typically limited by the solid-state diffusion of th
e ions inside the lattice. Volumetric changes that accompany the (de-)inse
rtion of ions further lead to degradation of the electrode materials. Thes
e factors contribute to the limited power and lifetime of LIBs. While some
of these limitations can be mitigated by nanostructuring of the electrode
material\, there is a large interest in finding structural motifs that al
low for intrinsically fast ion diffusion with reduced host lattice deforma
tion\, even in bulk-sized particles. In this presentation\, I will highlig
ht how interlayer properties\, such as interlayer distance and interlayer
chemistry\, affect electrochemical ion intercalation processes in layered
host materials. It is demonstrated that the presence of interlayer structu
ral molecules can increase the accessibility of intercalating ions to the
interlayer space and affect their transport properties. Increased interlay
er spacing and reduced deformation during ion intercalation can lead to a
change from diffusion-limited to non-diffusion limited (or pseudocapacitiv
e) charge storage behavior\, enabling favorable charge storage kinetics. T
he talk will give an overview of my research group’s efforts to synthesi
ze interlayer-functionalized layered and two-dimensional materials with ta
ilored interlayer properties towards high power intercalation electrodes a

erization.\nSpeaker: Dr. Simon Fleischmann

DESCRIPTION:Portable and stationary rechargeable batteries are within the m
any energy-related technologies that require fast progress within the urge
nt need of remediation of global climate. For example\, batteries can stil
l represent up to a third of electric vehicles emissions due to their manu
facturing process and lack of end-of-life management. Developing fundament
ally sustainable battery materials and electrode processing stands as a ce
ntral strategy for efficient battery recycling. One essential requirement
of next-generation battery technologies is the substitution of costly elem
ents like Li and Co by widely (and more evenly) available ones like Na and
Fe in the electrode materials. This implies the development of new energy
storage materials\, as well synthetic methods. Materials with porous and
hollow morphologies are one of the promising approaches in achieving long-
term stability in batteries. Such structures can buffer volumetric changes
associated with many energy storage mechanisms (like conversion reactions
or ion insertion)\, avoiding effects like aggregation\, structure collaps
e and loss of conductivity which leads to poor electrochemical performance
. Prussian blue (PB\, KFe[Fe(CN)6]) and its analogues (PBA\, AM
[M’(CN)6]) are cheap\, easy to synthesize\, non-toxic\, bioco
mpatible\, water and air-stable metal complexes. They have an intrinsic po
rous framework structure that allows ion intercalation with very little or
no strain. Their metal centers are electroactive in both organic and aque
ous media. Therefore\, this class of materials is ideal for battery electr
ode applications\, achieving high stability and capacity without the need
for complex synthetic routes. The tunability of PB(A) structure and compos
ition also makes them versatile template materials. Through different deri
vatization methods\, PB derivatives (PBD) can be prepared. Regardless of t
he relatively simple structure of PB(A)\, PBDs present an ever-growing num
ber of compositions that encompass metal oxides\, sulfides\, phosphides\,
carbides\, hybrids (among others)\, and an array of morphologies from simp
le cubes to highly complex hollow and porous structures. Such PBD have rec
ently demonstrated state of the art performance in catalysis and energy st
orage applications. This talk will give an overview of the current challen
ges and strategies to achieve high-performance sustainable batteries\, wit
h a focus on PB- and PBD-based electrode materials.\nSpeaker: Dr. Samantha

DESCRIPTION:Recovery and Utilization of Materials from electronic waste
via Cryomilling to Develop Advanced Green Technologies Krishanu Biswas
#Electronic waste (e-waste) causes enormous societal and enviro
nmental impact when they enter the trash stream. It has emerged as the fas
test-growing waste source in recent decades throughout the universe. The g
lobal accumulation of e-waste is expected to reach 74 Mt by 2030\, nearly
doubling in tonnage over this decade (2020-2030). The act of indiscriminat
e e-waste dumping\, along with inefficient and unorthodox e-waste handling
\, is indisputably detrimental to economic and public health. Since e-wast
e has dramatically increased the impact on the environment\, developing su
stainable solutions for recovery and recycling is of prime importance. In
this direction\, the present research aims to establish an easily scalable
and novel green technique to rejuvenate and effectively use metallic\, ce
ramic and polymeric components of the e-waste by use of cryo-grinding in a
n ecologically responsible and energy-efficient manner. The low-temperatur
e grinding method that breaks down PCBs all the way into nanoscaled partic
les\, further enabling enhanced physical separation of the different base
constituent materials that are the polymer\, oxide\, and metal. The recove
red materials are easy to be beneficiated as the nanoscale particles produ
ced from grinding are mostly single phase particles\, compared to the larg
er particles obtained by other methods that are multiphase mixtures of var
ious constituents. The metallic content is utilized to electrochemically s
electively reduce CO2 into distinct gaseous products\, resultin
g in the generation of CH4\, and H2 as main gaseous
products at neutral pH. On the other hand\, the extracted polymeric compon
ent is utilized to synthesize graphene/CNT using pulsed laser ablation (PL
A) in a liquid media\, showing promise in synthesizing high-quality graphe
ne\, which may be enhanced further by tweaking the PLA process parameters.
The synthesized graphene was utilized to fabricate highly conductive elec
trical connections\, revealing the excellent functional capacity of crysta
lline graphene. Polymeric content along with ceramic are being utilized fo
r making electrical switch boards. In a nutshell\, this green technique pr
ovided means of extracting main components from e-waste\, via low temperat
ure grinding\, which can then be utilized to make green energy\, precious
materials like graphene/CNT\, and other engineering applications in an eco
logically responsible manner\, making the process sustainable and hence\,
solving a global problem.\nSpeaker: Prof. Krishanu Biswas

DESCRIPTION: In-situ transmission electron microscopy (TEM) allows research
ers to analyse at the nano-scale and in ‘real time’ the electrochemica
l processes of the electrode materials within batteries during device oper
ation. The active interface regions of such electrodes form solid electrol
yte interface (SEI) layers during the charge and discharge cycling. The fo
rmation and movement of this functional SEI nano-interface is one of the m
ain research fields in battery science\, as it directly affects battery pe
rformance and lifetime. Of particular interest is observing the structural
and chemical evolution of this lithium-rich\, extremely complex polycryst
alline interface. Si nanowires are attractive materials for applications s
uch as lithium battery anodes due to their high theoretical capacity and u
ltra-low-cost for material sourcing and fabrication. The use of electroche
mically active metals such as Sn for the growth of Si nanowires contribute
s to the overall specific capacity of the electrode. This study explores t
he phase change in both the Si nanowire metal seed head and the nanowire S
EI layer during battery cycling. Our goal is to investigate the effect a c
hosen seed metal has on the Si electrode. We show that the lithiation/deli
thiation behaviour of the Sn-Si nanowire obtained using liquid cell was co
mparable to the result from bulk half-cell cycles and ex-situ analysis. Fi
nally\, we compare the benefits and drawbacks of liquid cell in-situ elect
rochemistry to cryogenic TEM analysis of the same system. Although in-situ
electrochemistry TEM offers many advantages over other characterisation t
echniques\, this analysis method is still in its infancy.\nSpeaker: Temi E

DESCRIPTION:In order to address climate change\, we must transition

motive power through two main routes: the Dry Cycle\, where metal powders/
sprays are burned with air\, or the Wet Cycle\, where metal powders are re

DESCRIPTION: Electrochemical energy storage is the key enabling component o
f electric vehicles and solar/wind-based energy technologies. The enhancem
ent of energy stored requires the detailed understanding of ionic transpor
t and electrochemical and electromechanical phenomena on local scales whic
h are not always accessible with classical electrochemical techniques\, su
ch as voltammetry. Therefore\, local probing of electrochemical and electr
omechanical behaviors on individual structural elements and heterogeneitie
s\, from grains to defects and further to individual atomic and molecular
species\, are invaluable. In this talk\, I want to introduce force-based a

rochemical processes on tens of nanometer and even molecular length under
electrochemical control. I will highlight the development and application
of in situ/operando force-based AFM methods to gain insight into the local
charge storage mechanism in a variety of energy related materials. In the
first part of the talk\, I will showcase how AFM can be used to investiga
te the structure and dynamics of the electric double layer (EDL) for elect
rochemical capacitors. I want to highlight work on room temperature ionic
liquids on model graphene electrodes since ionic liquids hold the promise
of increasing the electrochemical stability windows for electrochemical ca
pacitors. AFM was used to observe topological defects and show the existen
ce of structural domains parallel to the solid-liquid interface towards a
full picture of the double layer structure and their change with applied b
ias. In the second part of the talk\, I want to highlight how AFM-based me
thods can be used to study ionic transport and local electrochemical react
ions in supercapacitors and battery materials. Here\, electro-chemo-mechan
ical coupling is the key to study ion insertion pathways and heterogeneiti
es in local redox reactions. The first is demonstrated for the cation inse
rtion into layered Ti3C2 electrodes based on their change in mechanical st
iffness whereas the second is highlighted for proton insertion into WO3 wh
ere the relationship between electrochemical current and electrode strain
are discussed.\nSpeaker: Prof Nina Balke

DESCRIPTION: The advent of solid-state batteries has spawned a recen
t increase in interest in lithium conducting solid electrolytes. However\,
many open questions remain when trying to optimize electrolytes and under
stand solid state battery chemistries. In this presentation\, we will show
how an understanding of the structure-transport properties can help tailo
r the ionic conductivity. In an exemplary study on superionic lithium meta
l halides\, we show that a cation site-disorder and the local structure of
materials is important to study\, especially as synthetic influences cont
rol materials properties. In a second part of this presentation\, we will
show the tremendous influence of lattice dynamics on ionic conductors. By
introducing a different approach to understanding ionic motion using phono
n occupations\, we try to explain so far unexplained behaviors of physical
ionic transport. Finally\, we will show that it is not only important to
find fast ionic conductors\, but that fast ionic conduction is paramount w
ithin solid state battery composites. Measuring the effective ionic transp
ort in cathode composites provides an avenue to explore transport and stab
ility limitations that in turn provide better criteria for solid state bat
tery performance Bio: Wolfgang Zeier received his doctorate in Inorganic C
hemistry in 2013 from the University of Mainz. After postdoctoral stays at

encompass the fundamental structure-to-property relationships in solids\,
with a focus on thermoelectric and ion-conducting materials\, as well as s

DESCRIPTION: The NanoSIMS is emerging as a powerful tool to s
tudy complex problems in materials science. The NanoSIMS is a high-resolut
ion secondary ion mass spectrometry instrument capable of chemical mapping
at 100 nm spatial resolution\, detection limits in the ppm range and is a
ble to detect almost all elements in the periodic table as well as isotope
s. In this seminar I will show how we have been using the NanoSIMS to imag
e localised deuterium in electrochemically charged steel and nickel alloys
as well as in zirconium alloys oxidised in an autoclave to simulate nucle
ar reactor conditions. I will explain how isotopic tracers\, such as 18O a

DESCRIPTION: In order to address climate change\, we must transition
to a low-carbon economy. Many clean primary energy sources\, such as sola
r panels and wind turbines\, are being deployed and promise an abundant su
pply of clean electricity in the near future. The key question becomes how
to store\, transport and trade this clean energy in a manner that is as c
onvenient as fossil fuels. The Alternative Fuels Laboratory (AFL) at McGil
l University is actively researching the use of recyclable metal fuels as
a key enabling technology for a low-carbon society. Metal fuels\, reduced
using clean primary energy\, have the highest energy density of any chemic
al fuel and are stable solids\, simplifying trade and transport. The chemi
cal energy stored in the metal fuels can be converted to useful thermal or
motive power through two main routes: the Dry Cycle\, where metal powders
/sprays are burned with air\, or the Wet Cycle\, where metal powders are r
eacted with water to produce hydrogen and heat as an intermediate step bef
ore using the hydrogen as a fuel for various power systems. This talk will
overview the concept of metal fuels and the various power system options.
It will also touch on the combustion and reaction physics of metal fuels
and the propagation of metal flames. Bio: Jeffrey Bergthorson is the Panda
Faculty Scholar in Sustainable Engineering and Design\, and a Professor i

DESCRIPTION:The photovoltaic (PV) industry is in rapid growth and a large s
upply of PV feedstock materials must be provided to maintain this growth.
Since silicon is the dominant material for the fabrication of solar cells\
, low-cost solar-grade silicon (SoG-Si) feedstock is demanded. The most co
st-effective and direct approach for producing SoG-Si is to purify and upg
rade metallurgical-grade silicon (MG-Si). Many impurities in MG-Si can be
effectively removed through directional solidification of molten silicon.
However\, the removal of boron (B) and phosphorus (P) by this method is di
fficult and expensive due to the relatively large distribution coefficient
s of these elements. Therefore\, the elimination of B and P to the levels
required for SoG-Si feedstock requires the development of new processes. I
n the present study\, the effect of impurities on the solar cell efficienc
ies and the impurity contents in silicon materials are studied. The metall
urgical processes that can be applied to purify metallurgical silicon to s
olar grade silicon are reviewed and evaluated. It is shown that under deve
lopment metallurgical refining processes are applicable to produce solar g
rade silicon.\nSpeaker: Prof. Jafar Safarian

DESCRIPTION: In 2020\, every major company’s annual report contained the
word digitalization\, A.I. or industry 4.0. It is easy to perceive these a
s buzzwords\, aimed at investors\, but the reality is more complex: compan
ies are expected to transform now\, driven by the fear of becoming obsolet
e. As researchers\, this exciting transition creates significant opportuni
ties: huge amounts of data are becoming readily available\, while computin
g power and machine learning (ML) algorithms are more accessible than ever
. However\, this is also leading to disproportionate hopes and expectation
s regarding the actual capabilities of such methods\, that only a working
knowledge of ML combined with technical expertise in your field can ration
alize. As R&\;D engineers\, this critical view will be expected from yo
u. Since technical expertise has already been the focus of your profession
al career\, the effort should therefore be put on acquiring a practical kn
owledge of ML\, that is\, what problems can be solved and how to solve the
m? In this talk\, some applications of ML to solve industrial issues (pred
ictive modeling\, visualization\, combination with physical models...) wil
l be discussed. Furthermore\, practical aspects\, such as data preparation
\, models implementation and maintenance will be reviewed\, with the aim o
f providing actual insights on the root causes of successes and failures o
f ML applied to the steelmaking process.\nSpeaker: Dr. Guillaume Stechmann

DESCRIPTION: Bulk-type (inorganic) solid-state batteries are a promising ne
xt-generation energy-storage technology with the prospect of improving saf
ety and enabling higher energy densities than conventional lithium-ion bat
teries [1]. Especially high-capacity\, layered oxide cathode materials (NC
M or related) and lithium thiophosphate superionic solid electrolytes are
currently being considered for solid-state battery applications (at the po
sitive electrode side). However\, interfacial side reactions and chemo-mec
hanical degradation during cycling operation are major obstacles toward co
mmercialization of “practical” cells. In this presentation\, I will de
monstrate the importance of tailoring Ni-rich NCM materials in terms of si
ze and composition\, among others\, for improving the cycling performance
of pelletized and slurry-cast cathodes [2-4]. In addition\, I will show re
cent findings on the effects that coating chemistry and morphology have on
the side reactions\, including gas evolution\, in high-loading cells [4-6
]. [1] J. Janek\, W.G. Zeier\, Nat. Energy\, 1 (2016) 16141. [2] F. Straus

DESCRIPTION: What is the role of materials in today’s global economy as w
e deal with pressures from a growing population and a climate emergency? A
luminum production and usage helps provide food\, shelter\, health\, trans
portation\, and entertainment to the world. Achieving these goals in a “
sustainable” manner dictates that our materials “will impact positivel
y on society’s current needs and have no negative effects on future gene
rations to enjoy the same benefits.’ Life cycle analyses (LCA) of materi
als and products generally rate aluminum’s sustainability positively fro
m an accounting of the energy and usage costs through the product lifetime
. While plastic packaging\, in particular\, receives well-deserved bad pre
ss for polluting our world\, it is necessary for aluminum suppliers and us
ers as well to use our energy-intensive metal wisely. The talk will review
the current production and carbon emissions footprint for primary aluminu
m and the role of recycling and secondary operations in the industry. Note
that the analysis will take into account the sources of energy (renewable
or fossil fuel) in different parts of the world. What is the current stat
e of aluminum primary production? What adaptations are taking place?What i
s the prospect for new aluminum production technology?How do buildings\, t
ransportation and packaging markets stand in regard to production\, use\,
re-use and recycling?What are the roadblocks to maximizing re-use and recy

DESCRIPTION: Machine learning and artificial intelligence (ML/AI) are rapid
ly becoming an indispensable part of physics research\, with domain applic
ations ranging from theory and materials prediction to high-throughput dat
a analysis. In parallel\, the recent successes in applying ML/AI methods f
or autonomous systems from robotics through self-driving cars are generati
ng enthusiasm for the potential of these techniques to enable automated an
d autonomous experiment (AE) in areas ranging from materials synthesis to
imaging. The implementation of this vision requires the synergy of three i
ntertwined components\, including the engineering controls of the physical
tools\, the algorithmic developments that allow to define non-trivial exp
loratory patterns\, and physics-driven interpretation. In this presentatio
n\, I will discuss recent progress in automated experiment in electron and
scanning probe microscopy\, ranging from feature finding to physics disco
very via active learning. The applications of classical deep learning meth
ods in streaming image analysis are strongly affected by the out of distri
bution drift effects\, and the approaches to minimize though are discussed
. We further present invariant variational autoencoders as a method to dis
entangle affine distortions and rotational degrees of freedom from other l
atent variables in imaging and spectral data. The analysis of the latent s
pace of autoencoders further allows establishing physically relevant trans
formation mechanisms. Extension of encoder approach towards establishing s
tructure-property relationships will be illustrated on the example of plas
monic structures. Finally\, I illustrate transition from post-experiment d
ata analysis to active learning process. Here\, the strategies based on si
mple Gaussian Processes often tend to produce sub-optimal results due to t
he lack of prior knowledge and very simplified (via learned kernel functio
n) representation of spatial complexity of the system. Comparatively\, dee
p kernel learning (DKL) methods allow to realize both the exploration of c
omplex systems towards the discovery of structure-property relationship\,
and enable automated experiment targeting physics (rather than simple spat
ial feature) discovery. The latter is illustrated via experimental discove
ry of the edge plasmons in STEM/EELS and ferroelectric domain dynamics in
PFM. This research is supported by the by the U.S. Department of Energy\,

is a common fuel in batteries\, while aluminum is frequently added to soli
d rocket propellants and used in pyrotechnics. At high temperatures\, meta
l powders can be burned in air in a similar way to hydrocarbon fuels\, rel
easing chemically stored energy as sensible heat. Contrary to hydrocarbon
combustion\, however\, the main reaction products are solid oxide particle
s that can\, in principle\, be retrieved from the exhaust fumes. This amen
ability to oxide sequestration has stimulated the idea of harnessing metal
powders as recyclable energy carriers which are burned\, retrieved and\,
subsequently\, recharged by a reduction process based on clean primary ene
rgy. Conceptually\, the metal powders are akin to high-temperature batteri
es\, serving as a means to buffer the large spatial and temporal intermitt
ency associated with renewable energy sources. Motivated by the potential
use of metal powders as recyclable fuels\, we qualitatively discuss the ph
ysical and chemical processes involved in the combustion of a single metal
particle and of metal dusts\, respectively. Subsequently\, a population b
alance model for predicting the size distribution of the oxide smoke preci
pitating in the vicinity of a single burning aluminum particle is presente
d. Here\, we specifically focus on the kinetic rates that control the phas
e transitions and smoke dynamics\, integrating recently developed detailed
kinetics for gas phase and heterogeneous surface reactions. The populatio
n balance equation governing the oxide size distribution is solved with th
e aid of a tailored adaptive grid method. An alternative\, potentially mor
e economical solution approach we propose is based on an embedded reduced
order representation of the particle size distribution that is informed by
a training step. The accuracy and convergence properties of this method a
re investigated for a simplified test case involving particle growth and d
ispersion in a laminar plane jet. In the final part of the seminar\, the p
hysical description\, from an Eulerian viewpoint\, of metal powders is dis
cussed with a particular emphasis on the ramifications of carrier flow tur
bulence. In order to account for the small-scale interactions between disp
ersed particles and the ambient gas phase\, the population balance equatio
n governing the metal powder or oxide smoke is integrated into a probabili
stic description that naturally accounts for the variability among indepen
dent realizations of a turbulent\, particle-laden flow. Owing to the high
dimensionality of the resulting transport equations\, a stochastic solutio
n approach based on Eulerian stochastic fields is proposed for which we sh
ow preliminary accuracy and convergence analyses.\nSpeaker: Dr. Fabian Sew

DESCRIPTION: Abstract: Many layered materials of interest for electrochemic
al energy storage and conversion applications are flexible hosts whose int
erlayers can be expanded to accommodate not just ions but also solvents\,
organic molecules\, polymers\, and organometallics. When these “hybrid
” materials are placed into an electrochemical environment\, the distinc
tion between surface and bulk becomes blurred since the electrochemical in
terface can now be viewed to extend into the interlayer. During this semin
ar\, I will discuss fundamental aspects of charge storage at electrochemic
al interfaces and how interfacial charge storage and reactivity change und
er confinement. I will also describe synthesis of hybrid layered materials
and the use of in situ and operando characterization to und
erstand the relationships between structure and composition and the result
ing electrochemical reactivity.\nSpeaker: Prof. Veronica Augustyn

DESCRIPTION: Engineered systems are an indispensable part of our modern lif
e with far-reaching applications that include aerial and ground transporta
tion\, electronics\, large-scale structures\, and medicine. The ever-evolv
ing societal\, environmental\, and cultural awareness calls for significan
tly complex systems with unprecedented properties that reliably meet stake
holders’ demands under extreme conditions. To accelerate the design and
deployment of such systems while reducing the reliance on costly and time-
consuming experiments\, it is necessary to develop advanced computational
methods that streamline their design and analysis process. In this talk\,
I will present some of our recent works for solving challenging problems i
n engineering design\, solid mechanics\, and fluid dynamics. In particular
\, I will demonstrate how we can (1) accelerate multiscale simulations of
casting materials ten times via mechanistic reduced order models\, (2) sur
rogate plastic and history dependent deformation of fiber composites with
deep learning\, (3) optimize material composition with latent map Gaussian
processes and Bayesian optimization\, and (4) solve partial differential
equations with transfer learning.\nSpeaker: Dr. Ramin Bostanabad

DESCRIPTION: Metal powder has superior energy density compared to fossil fu
els and hydrogen. Therefore\, metal powders have gained interest as a mate
rial for energy storage. The main benefits of metal fuels are that they do
not produce CO2 emissions during combustion\, they have the potential to
be retrofitted in existing coal power plants and they can fit into the exi
sting fuel transportation infrastructure. Furthermore\, this enables the p
roduction of sustainable energy since metal fuels can be regenerated from
metal oxides\, using hydrogen from renewable sources. In this presentation
\, the main characteristics of metal fuels are presented with a final focu
s on clean combustion. A series of burners has been developed: - single pa
rticle or fuel jet in a micro burner to study single particle combustion a
nd particle-particle interaction - Bunsen-type burner for stabilizing lami
nar and weakly turbulent premixed flames - Tornado-swirl burner First nume
rical studies are also started for comparison. Furthermore\, a 100 KW demo
nstrator set-up is developed to demonstrate clean combustion to produce st
eam (placed at Swinkels brewery and Metalot centre). Studies to scale up a
re also conducted. The main objective of this practical systems is the dev
elopment of an integrated flexible metal fuel burner with a capacity of 10
0 KW (TRL5). This is an essential step towards implementation of this sust
ainable technology. This project forms the basis to further develop full s
cale burners with a capacity of 10 MWth. The development of the prototype
burner is executed by a consortium which covers the entire supply chain. T
his includes the production of metal powder\, fuel preparation\, burner an
d combusted product handling. The industrial partners have broad experienc
e in metal powder supply\, dense energy carriers and operating coal fired
power plants. Furthermore\, techno-economic analyses and the assessment of
retrofit potential to existing assets will be carried out. Status-quo wil
l be presented\nSpeaker: Prof. Philip de Goey

DESCRIPTION: In this presentation the formation of spinel (MgAl2
O4) by reaction between periclase (MgO) and corundum (Al2<
/sub>O3) is addressed. The reaction MgO + Al2O3
=>\; MgAl2O4 may be regarded as a model cas
e for diffusive phase transformations in oxide systems. All phases involve
d are moderately to highly refractory and have applications in ceramics. A
bove about 800°C\, periclase and corundum react to form a layer of polycr
ystalline spinel at their interface. A pronounced dichotomy of the interna
l microstructure and texture of the spinel layer reveals the original posi
tion of the periclase-corundum interface. This reflects the direction and
extent of the necessary Mg2+ and Al3+ transfer acros
s the spinel layer and allows to quantify the underlying diffusion process
. Systematic deviations of the Mg/Al ratio of the spinel from local equili
brium values at the spinel-periclase and the spinel-corundum interface are
due to a finite mobility of the two reaction interfaces. The resistance a
gainst interface motion arises from dislocation climb at the periclase-spi
nel interface\, which is complemented by the formation of Schottky defects
in the reactant periclase. In contrast\, the corundum-spinel interface mo
ves by the glide of partial dislocations. This is energetically less expen
sive than the dislocation climb at the periclase-spinel interface and allo
ws for comparatively rapid approximation of local equilibrium.\nSpeaker: P

DESCRIPTION: The extraction and processing of resources are directly linked
to 50% of all human-induced climate impacts and 90% of biodiversity losse
s (Bruno Oberle et al.\, 2019). Promoting resource efficiency is therefore
recognised worldwide as a solution approach to counteract this rapid deve
lopment. The circular economy (CE) approach brings new dynamism to the dis
cussion of the well-known concept of resource efficiency (van Ewijk\, 2018
\; Weizsäcker et al.\, 1997). Both approaches aim to reduce resource use
and thus prevent tremendous environmental impacts. For example\, the CE is
thought to be crucial for reaching climate neutrality by 2050 as well as
decoupling of economic growth and resource use (European Commission\, 2020
). Studies estimate that eco-design\, waste prevention and reuse may resul
t in up to EUR 600 billions of savings for businesses in Europe (Kalmykova
et al.\, 2018). The metal industry is of high importance in this discussi
on as metal production is responsible for 8% of the global energy expendit
ure (UNEP 2013). Steel production alone is responsible for a quarter of al
l industrial GHG emissions (Allwood et al.\, 2011\; Ito et al.\, 2020). Ho
wever\, the metal industry and especially the steel industry can look back
on a long history of recycling as a core principle of the CE resulting in
great resource savings. Nevertheless\, there are major doubts as to wheth
er future steel production can be covered entirely by secondary material.
This is due to the dependency of the recycling infrastructure on primary m
etallurgy\, the limits of recycling and the low degree of circularity of s
teel (Haas et al.\, 2015\; Pauliuk\, Wang\, et al.\, 2013\; Steger et al.\
, 2018\; Xylia et al.\, 2018). In the presentation\, the challenges of res
ource use in general as well as the possible strategies of the Circular Ec
onomy are presented and their applicability for the field of metals\, in p
articular steel\, is discussed. To illustrate this\, project examples will
be presented in which\, on the one hand\, the CE strategies of re-purposi
ng/re-manufacturing and\, on the other hand\, a technical approach of sort
ing by specific type for recyling will be illustrated.\nSpeaker: Prof. Dr.
