Andreas' research focuses on the development of in situ and operando liquid-phase transmission electron microscopy (LP-TEM) techniques and their application in energy research and materials sciences for studying dynamic processes at the nanoscale. Those processes comprise degradation and growth kinetics and mechanisms of nanomaterials and electrocatalysts under operational conditions. Besides understanding, modeling, and quantifying electron-beam induced effects in irradiated liquids, Andreas' research aims toward LP-TEM to become a quantitative characterization method. LP-TEM studies are, furthermore, complemented by conventional and identical location TEM studies into structure, composition, and structure-functionality relations of various nanomaterials comprising electrocatalysts and composites, catalyst-coated membranes, alloyed, or core-shell nanoparticles, and ionomers. In particular, Andreas is PI in the BMBF project StacIE within the H2Giga consortium in which degradation effects in proton-exchange membrane water electrolysis are analyzed using complementary and scale-bridging techniques including (IL) TEM, SEM, SFC/ICP-MS, and full cell testing.
