Abstract:  Liquid interfaces play an important role in many chemical and biological systems in addition to being interesting model systems to study the statistical physics of interfaces and membranes.  As examples, water-oil interfaces are a model for the interaction of water with a hydrophobic molecular environment, important for protein folding and the formation of structures in complex fluids.  Also, biological membranes exist at the interface between two aqueous regions and provide a dynamic platform for important cell processes.  X-ray scattering measurements of liquid interfaces allow for the study of ordering and fluctuations on the nanometer length scale.   We will discuss ordering and phase transitions in molecular assemblies located at the interface between two bulk liquids, and the effect of liquid structure on the distribution of ions near liquid-liquid interfaces.
