  • Date: Nov 14, 2023
  • Time: 10:00 AM - 11:00 AM (Local Time Germany)
  • Speaker: Dr.-Ing. Vijayshankar Dandapani
  • Dr. -Ing. Vijayshankar Dandapani is an Assistant Professor at the Metallurgical Engineering and Materials Science Department, Indian Institute of Technology (IIT), Bombay. He is an alumnus of the Max-Planck-Institut für Eisenforschung GmbH (MPIE), Düsseldorf where he did his PhD work with PD Dr. Michael Rohwerder. His current research is in using electrochemical impedance spectroscopy to characterise hydrogen and stress induced interface changes relevant for corrosion of metals.

Hydrogen permeation based potentiometry is a recently developed experimental technique to measure electrochemical oxygen reduction reaction (ORR) rates at in-accessible polymer/metal interfaces relevant for corrosion driven coating delamination. In this talk, the results from combining electrochemical impedance spectroscopy with this technique to correlate interfacial charge transfer resistance during polymer degradation with corresponding current-potential i.e; I(U) curve for ORR kinetics will be shown.

An atoms eye view of Solar System Evolution

An atoms eye view of Solar System Evolution
  • Date: Sep 15, 2023
  • Time: 10:00 AM - 11:00 AM (Local Time Germany)
  • Speaker: Dr. Luke Daly, University of Glasgow, Scotland, UK
  • Dr Luke Daly is a Reader in Planetary Geoscience at the University of Glasgow. He completed his MSc degree in Geology at Imperial College London. His PhD was with Prof. Phil Bland at Curtin University Australia which focused on platinum group element alloys in meteorites. His current research focusses on applying correlative microscopy including atom probe tomography to meteorites and asteroid sample return mission materials in order to understand how our Solar System formed and evolved: in particular, trying to answer the question of how Earth became a habitable planet. He is a participating scientist on JAXA's Hayabusa 2 mission and treasurer of the UK Fireball Alliance - a network of meteor cameras that successfully recovered the Winchcombe meteorite in 2021.

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.
