TL;DR: This work studies the hydriding phase transformation in individual palladium nanocubes in situ using coherent X-ray diffractive imaging and provides a general framework for designing and optimizing phase transformations for single nanocrystals in reactive environments.
Journal ArticleDOI
Three-dimensional imaging of dislocation dynamics during the hydriding phase transformation

TL;DR: This work uses Bragg coherent diffractive imaging to image defects during the hydriding phase transformation of palladium nanocrystals and reveals how particle size and phase morphology affects transformations in the PdH system.
Journal ArticleDOI
Active site localization of methane oxidation on Pt nanocrystals
