COLLOID AND SURFACE SCIENCE:

APPLICATIONS TO TECHNOLOGY
(VIDEO LECTURE SERIES)

The aims of this video lecture series are to trace the history and gain a basic understanding of colloid and surface phenomena in different technologies such as coating, painting, lithography, soldering, welding, flotation, foaming/defoaming, emulsions/demulsification, wetting, spreading, and adhesion. The series is designed to show what governs the phenomena in colloid and surface science and explore the ways that colloid and surface science can solve technological problems.      
Colloid and surface science (CSS) is an inter-disciplinary area of physics, chemistry, material science and biology.  CSS includes two major topics: surface science, which focuses on the texture and stability of foams, emulsions, and films on liquids and solids, and colloid science, which covers the texture and stability of colloids, suspensions, aerosols, microemulsions, soles, and micellar solutions. (Colloidal dispersions are dispersed systems with a nano-sized dispersed phase.)
