Surface and Interfacial Science
Maj Jennifer Gresham, Program Manager
Understanding the chemistry, physics and mechanics of surfaces and their interfaces is critical to a wide range of Air Force technologies, particularly as we look towards miniaturization of assets. This program is interested in discovering fundamental mechanisms of behavior that could later be used to guide material design with specific surface and interfacial properties. The focus is on chemical and physical mechanisms that apply to a wide range of materials rather than Edisonian investigations of individual materials, unless these are used solely as a proof of principle.
The research currently funded under this program falls into two broad categories: tribology and thermal transport. The tribology program investigates basic chemical phenomena at the interface through experiments and molecular dynamics, fundamental mechanisms of friction and wear, multi-scale investigations of tribological properties, and the development of tools for the in situ monitoring of tribological and mechanical properties. The thermal transport program aims to understand the mechanisms responsible for nano-scale thermal transport between dissimilar materials at the molecular level to determine how heat is transferred across the boundary between two materials. In particular, the program hopes to understand how surface chemistry may be used to create materials and structures with unprecedented and/or tunable thermal and spectral properties. For both programs, solid/solid and solid/fluid interfaces with relevance to Air Force applications are of interest.
