This program focuses on molecular level studies of surfaces and interfaces to determine the mechanisms that govern their physical, chemical, and tribological properties. Single crystals and nanocrystals are the key materials investigated. We develop techniques and methods that make possible surface sensitive microscopy and spectroscopy studies of surfaces under ambient conditions.

With the support of the DOE BES, our group develops new methods and instrumentation based on nuclear magnetic resonance for the non-invasive investigation of materials at all length scales. We seek to decrease the dependence of magnetic resonance on the expensive infrastructure of superconducting magnets and cryogenics and to enable new applications with enhanced portability and sensitivity. Current emerging novel methodologies include functionalized magnetic resonance molecular and surface sensors, magnetic resonance detection by laser atomic magnetometry, nanodiamond defect optics and spin hyperpolarization, and magnetic resonance on microfluidic chips. We collaborate with other MSD core programs both to develop new materials and structures used in our own experiments and to pursue exemplary applications to materials science.
