state physicist by training, Prinz leads a group of doctoral students who are addressing fundamental issues on energy conversion and storage at the nanoscale. In his Laboratory, prototype fuel cells, solar cells and batteries are used to test new concepts and novel material structures using atomic layer deposition, scanning tunneling microscopy and other(More)
This study presents atomic scale characterization of grain boundary defect structure in a functional oxide with implications for a wide range of electrochemical and electronic behavior. Indeed, grain boundary engineering can alter transport and kinetic properties by several orders of magnitude. Here we report experimental observation and determination of(More)
