Introduction to soft condensed matter: a range of applications and products including foods, cosmetics, pharmaceuticals, ceramics, suspensions, minerals and detergents. The course covers the fundamental structure-function and material properties of these complex systems.
The colloidal domain: brownian motion and the Stokes-Einstein equation. Suspension viscosity.
Interparticle forces: dispersion forces, electrostatic forces (Poisson-Boltzmann), double layer theory and solvation forces. The role of surface forces in colloidal stability. Electrokinetic characterization of nano-particles and the relationship to colloidal stability and suspension rheology. Suspension rheology, measurement, viscoelasticity and the colloidal state. Polymer physics. Polymers as random walks, ideal and real chains scaling concepts and the size of the random walk. Entropy and Elasticity, the Hookean spring. Viscoelastic behaviour of polymer solutions and melts. Gels, sols and gelation including the concept of percolation. The theory of rubber elasticity. Adsorption of polymers to surfaces. Surfactants and self assembly. Micelles, vesicles and hexagonal phases. Aggregation numbers and packing parameters. Lipid bilayers. A review of several papers in biotechnology and nanotechnology.
