Description

Clusters (sometimes called nanoclusters) are materials with sizes ranging from complexes involving just a few atoms or molecules up to small nanometer-scale structures. Due to their small size, they often exhibit surprising behaviors arising from strong quantum effects. The unique chemistry found in nanoclusters makes them attractive as high energy materials, next-generation catalysts, and advanced sensors. In addition, the interactions which govern them are often keys to understanding important phenomena observed on larger scales. This research program focuses on formation and characterization of nanoclusters that support new propulsion or energy capabilities, and development of advanced diagnostic methods to record their structure, energetics, and dynamics.
