The ability of a benchtop powder X-ray diffractometer with a solid state detector to observe
the ambient oxidation of ultrasmall (sub 2.5 nm) Pt particles, previously seen only with …

To improve the understanding of catalysts, and ultimately the ability to design better
materials, it is crucial to study them during their catalytic active states. Using in situ or …

CeO2 and cerium-based materials can store oxygen under excess-oxygen conditions and
release it under oxygen-deficient conditions, and owing to the high oxygen storage/release …
