Description
This lecture delves into the phenomenology of suspensions and emulsions, covering topics such as particle concentration, size, and shape, as well as the influencing factors on suspension stability. The instructor discusses various interaction forces like electrostatic, depletion, and hydrodynamic interactions, along with the concept of steric repellency. The lecture also explores the osmotic pressure, Brownian motion, and the double layer phenomenon in colloidal suspensions. Emulsions are examined, including stability factors, types like water-in-oil, and the role of stabilizing agents. The session concludes with insights into margarine viscosity, emulsion formation, and the Ostwald ripening phenomenon.
