Colloid and interfacial phenomena play a central role in many industrial, environmental, and biomedical areas, as well as in emerging technologies. These include detergency, emulsification, and wetting; enhanced oil recovery and other petrochemical processes; personal care products; drug delivery systems; thin films; and microfabrication of electronic and electro-optic devices. CHEB313 is intended to provide an introduction to theoretical, experimental, and applied aspects of colloidal systems, as well as interfacial phenomena.
