The surface chemical composition of supported single Pt–Rh core–shell nanoparticles was studied to understand the Rh behavior in oxidizing and reducing gas environments using spectro-microscopy with ...

Using a technique called secondary ion mass spectrometry (SIMS), they collected 1,217 individual measurements of stable oxygen isotopes, including one called oxygen-18. Huerta explained that the ...

Traditionally, single nanoparticle collision experiments have been used to understand fundamental properties about nanoparticles at the highest resolution─one at a time. However, this technique shows ...
