Materials design through interface engineering

Although they are sometimes viewed as no more than dividing surfaces between neighboring constituents, solid-state interfaces in fact have distinct physical properties of their own. We are using the properties of interfaces to design new materials with radically enhanced performance under extreme irradiation and mechanical loading.
