As electron microscopists, we are interested in probing the dynamics of physical and chemical processes of functional materials at the molecular and atomic scales in an atom by atom fashion. With fundamental understanding of material behavior at discrete structural features such as defects and interfaces, we can harvest unique properties outside of equilibrium conditions and engineer better materials for energy harvesting and conversion.
