| Aim: To provide the students with an understanding of the fundamental concepts and general physical and chemical laws that describe interfaces and the phenomena which are associated with and controlled by interface formation as it occurs in physical, chemical and biological systems. The description includes solid/gas, solid/liquid, liquid/liquid, as well as solid/solid interfaces. The emphasis is put on an understanding of the fundamental principles which underlie formation, stabilization and destabilization of interfaces and how complex interface phenomena are controlled by simple equilibrium and non-equilibrium conditions. The interface phenomena described are of relevance in systems like soaps, emulsions, colloidal systems, biological membranes, catalysts, organic thin films and enzyme systems. |
Contents: Interfacial tension, wetting and contact angles. Thermodynamics of interfaces. Amphiphiles in water. Aggregation and self-assembly. Micelle formation. Lipid monolayers, bilayers, vesicles and hexagonal phases. Structure and dynamics of lipid monolayers at air/water interfaces. Lipid bilayers as model membranes. Phase transitions and phase equilibria in membranes. Interfaces induced by fluctuations. Dynamic membrane heterogeneity. Interfacial catalysis and interfacially active enzymes. Control of interfaces by foreign molecules: Drugs and insecticides. Structured and complex fluids: Emulsions, microemulsions, block co-polymers and liquid crystals. Dynamics of liquid-liquid interfaces. Interfacial instabilities and viscous fingering. Diffusion in porous media and percolation. Equilibrium shapes of crystals and dendritic growth. Diffusion-limited aggregation and fractal patterns. Domain growth and grain growth in solids. Dynamics of random networks of interfaces and phase separation.
