CHEM E 455
Laboratory techniques, equipment, and underlying fundamentals in surface and colloid science. Experiments in the measurement of surface tension, adsorption, wetting and spreading, colloid properties, emulsion preparation and stability, electrophoresis, and interfacial hydrodynamics. Recommended: CHEM E 326; CHEM E 330. Offered: ASp.
The behavior of fluid interface systems (capillarity), fine particle dispersions, fibers and thin films is dominated by the properties of their interfaces. Such systems play critical roles in many fields: chemical industry, biotechnology, chemical engineering, food science, material science, agriculture and medicine, to name a few. The underlying science of interfacial phenomena is rarely treated in university courses in chemistry, physics or engineering, and the practitioner is left to solve problems in the area without the needed background. This course seeks to develop the scientific background of the subject, to trace the consequences of the science into industrial practice and everyday experience, and to teach laboratory techniques for property measurement and system characterization.

General method of instruction
Previous lab experiences are highly recommended.
Class assignments and grading
There are 4 labs. Each lab is worth 20pts. The breakdown is as follows *10pts: attendance (come in ontime, leave as told) *5pts: prelab questions and lab performance *5pts: post lab quiz on 2nd lab day (answers might be given during the lab)
