Kevin Schweinar, MSc

• Surface composition/structure changes during catalyst synthesis and operation
• Understanding degradation mechanisms
• Development of structure-function relationships

I develop my main expertise around synchrotron-based (in-situ) surface spectroscopy techniques and atom probe tomography. Correlative experiments combining those methods help to link surface properties of materials to their local atomic-scale chemistry. 

Further projects:

• Surface dynamics on silver-based alloys during heterogeneous catalysis
  Collaboration with MPI CEC 
• Investigation of geological materials with APT (e.g. feldspars, zircons, pyrites) 
  Collaborations with groups at University of Vienna, University of Wisconsin-Madison and University of Ottawa
• Nanoparticles in the atom probe
  Collaboration with Dept AC at University Duisburg-Essen
