“My goal is to synthesize nanomaterials for application as electrocatalysts in fuel cells in order to boost the efficiency of these devices in converting chemical energy into electrical energy. These devices could soon replace combustion engines in cars. To do so, I use the TEM-FEG transmission electron microscope at LNNano. Microscopic analyses generate data on the shape of the nanoparticles and how the different elements used in synthesis are distributed throughout these nanomaterials.”
