Solid State Chemistry/Spectroscopy and Dynamics

Interfaces are integral parts of composite materials and can significantly affect their physical and chemical properties. In biological systems, for example, molecules at the interfaces regulate mineral formation or mitigate structural mismatch of the organic and inorganic moieties to provide optimal mechanical properties. In energy storage systems, interfacial processes play a key role in charge and mass transport, degradation, and safety. A thorough fundamental understanding of these underlying interfacial processes has important scientific and engineering implications. However, due to the intrinsic nature of interfaces being ??buried?? and disordered, it is very challenging to reveal chemical, structural, and dynamical information at interfaces.
