We are interested in understanding the structure and function of nanomaterials and nanostructures related to energy and the environment. Within this general theme, our research can be divided into several areas. A major focus is in the area of in situ atomic level characterization of materials for applications to energy production. This includes projects on:

  • metal and oxide nanocatalytic materials
  • photocatalytic semiconductors for solar fuels
  • oxide ion conductors for fuel cells

Other research interests include characterization of atmospheric aerosol nanoparticles and their influence on climate change.

We specialize in applying transmission electron microscopy (TEM) based imaging and nanospectroscopy techniques, especially with in situ capability, to these important scientific areas. We access cutting edge aberration corrected TEM and monochromated electron energy-loss spectroscopy.

We would like to acknowledge the gracious support of the following agencies and institutions – our work would be impossible without them.
