Atom probe tomography is a well-established analytical instrument for imaging the 3D
structure and composition of materials with high mass resolution, sub-nanometer spatial …

Given the binary nature of nanoalloy systems, their properties are dependent on their size,
shape, structure, composition, and chemical ordering. When energy and entropic factors for …

We report a unique in situ instrument development effort dedicated to studying gas/solid
interactions relevant to heterogeneous catalysis and early stages of oxidation of materials …

Activating pretreatments are used to tune surface composition and structure of bimetallic-
alloy catalysts. Herein, the activation-induced changes in material properties of a …

Photoelectrochemical cells have the potential to convert solar energy to liquid fuels.
Nanostructured electrode materials are attractive light-harvesting materials for this purpose …

Au-based materials are remarkably efficient catalysts in the domain of partial oxidation
reactions. Nonetheless, questions remain about the physico-chemical phenomena involved …

In this study, the full reaction mechanism for N2O hydrogenation on silver doped Au (210)
