Colloids and Surfactants (CHEM735) (MPhil (Physical) Chemistry-II-Regular)

This course is designed for MPhil (2nd Semester) Physical Chemists. The purpose of this course is to make the students capable of understanding theory of Colloids, Suspensions, Miscellars and about the Surfactants. The course is advanced and makes the students capable of preparing colloids, emulsion and surfactants at lab scale which may be extensively used in research.  

Contents

Liquid interfaces, surface tension and adsorption from solution, insoluble surface monolayer (Langmuir-Blodgett films). Surfactant, detergency, organized molecular assemblies (micelles, vesicles and membranes). Micro and macro emulsions. Colloidal dispersions, coagulation and flocculation. Optical properties of colloids.
