Instructor Class Description

Time Schedule:

Felix Nhanchau Nguyen
CHEM E 455
Seattle Campus

Surface and Colloid Science Laboratory

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.

Class description

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.

Student learning goals

General method of instruction

Recommended preparation

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)


The information above is intended to be helpful in choosing courses. Because the instructor may further develop his/her plans for this course, its characteristics are subject to change without notice. In most cases, the official course syllabus will be distributed on the first day of class.
