The chemical, physical and biological properties of an interface often differ significantly from that of the bulk due to surface energetic and entropic effects. The composition and conformation of molecules at an interface are responsible for a wide range of phenomena observed in materials science and biology. Solid-liquid interfaces for example, are crucial in lubrication, biocompatibility, drug delivery and corrosion. Liquid-liquid and liquid-gas interfaces are important in lipid membrane fusion, water pollution and acid rain. Several faculty members in the department are using a combination of theoretical, spectroscopic and microscopic techniques including ellipsometry, force microscopy, electron microscopy and X-ray photoelectron spectroscopy to elucidate the structure of interfaces of solids and liquids with molecular scale resolution. Of specific interest to us is surface modification for enhanced physical properties, pattern formation at solid and liquid interfaces and interfacing biological media.
