Colloids and Interfacial Science

3 Units

Fundamental aspects of colloidal suspensions, surface tension, wetting, surfactant adsorption, self-assembly, and interparticle interactions. DLVO theory, stability criteria, and coagulation kinetics. Electrokinetic phenomena. Applications to electrophoresis, filtration, floatation, sedimentation, and suspension rheology. Investigation of suspensions, emulsions, gels, and association colloids. Emphasis will be placed on the importance and application of these phenomena to consumer, industrial, and biomedical applications. Recommended preparation: CHEM 335 . Offered as ECHE 366 and ECHE 466 . Prereq: Junior or Senior student standing.
