Welcome to the Newberg research group website
For many applications in energy and environmental science, understanding the surface chemistry of interfaces is where the achievement lies. However, the ability to probe interfaces quantitatively on a molecular level with chemical specificity is technologically challenging under ambient conditions. This is due, in part, to the paucity of instrumentation with the ability to directly probe the chemical state of surface atoms and molecules quantitatively under natural (environmental) or operational (catalytic) conditions. We are a multidisciplinary research group with interests in developing and utilizing in situ surface spectroscopy probes to understand the mechanisms and energetics of vapor uptake at solid and liquid interfaces. Surfaces of interest include metals, metal oxides, ionic liquids, alkali/halide salts and ice. This research has implications in catalysis, photocatalysis, electrocatalysis, tribology, environmental and atmospheric chemistry.
