Liquid Phase Electron Microscopy
Our research aims to derive the critical structure-property relationships that control the performance of nanoscale catalysts through in situ characterization with electron microscopy and its associated spectroscopic techniques. In particular, we are interested in operando studies where the imaging of catalysts in liquid environments is coupled with concurrent measurements of their reaction kinetics. This approach will allow us to directly interrogate the structure and composition of these catalysts under reaction conditions and generate insights that can be used to inform the rational design of these nanomaterials.
Other areas of interest of the group include: (1) automated image processing of high frame count electron microscope image sequences, (2) advanced image analysis of noisy images acquired at low electron fluences, and (3) the development of multi-modal approaches towards catalyst characterization using methods complementary to electron microscopy.
