Abstract

Hydrogen Detection By combining electron loss spectroscopy with in-situ gas TEM, hydrogen concentration is measured in a model system consisting of cubic palladium nanoparticles, with a lateral resolution down to 4 nm. The versatility of in-situ TEM allows to link together microstructure, hydrogen concentration and local strain, opening up a new chapter in hydrogen research.
