    Roland Bliem

    Postdoctoral Associate

    Phone: 617-324-7068

    Education:
    MSc (Physics) and PhD at the Institute of Applied Physics, Vienna University of Technology, Austria

    Roland's research is focused on the surface properties of solid oxide fuel cell cathode materials, in particular Sr-doped LaMO3 perovskites (M=transition metal). He aims to understand the driving forces of segregation processes at these surfaces and relate them to basic surface properties, such as structure, defect concentration, and reducibility. Previous work in the EC interfaces group [Nat.Mater. 15, 1010 (2016)] shows that these basic surface properties can be modified by the deposition of low coverages of metals, influencing the stability of the cathode material. Roland attempts to resolve the origin of the (de)stabilizing effects of these metal species. In parallel, he tests if stabilizing effects observed close to operation conditions can be generalized to include further state-of-the-art perovskite cathode materials.

    Dr. Franziska Hess is a postdoctoral associate at the Department of Nuclear Science and Engineering. She studies (electro-)catalytic reactions on surfaces applying a combination of experiments and/or density functional theory with Kinetic Monte Carlo simulations. The aim of her research is to understand the interplay between intrinsic material parameters (such as adsorption energies, activation energies, ion misfit) and extrinsic parameters (temperature, partial pressures, bias voltage) and their effect on the overall reaction kinetics and material stability in order to improve material and process parameters.

    My research interests lie on embrittlement process of iron sulfide films in the existence of hydrogen. This process is substantially important to sub-sea infrastructure of off-shore oil platforms and understanding the effect of hydrogen on this process could help finding a new solution against such extreme environments. In particular, I am looking at the effect of hydrogen in bulk mackinawite structure using DFT.
