Dispersions in Liquids: Suspensions, Emulsions, and Foams
Help solve your colloidal, foam, and dispersion problems in this course designed for scientists and engineers engaged in research and development in the chemical, petroleum, coatings, food, electronics, pharmaceutical, cosmetics, and ceramics industries; covering topics such as surface and interfaces, surfactants, nanoparticle technology, interparticle forces and stability, laboratory techniques, emulsion technology, dispersion processing, foam technology, and polymer stabilization.
- Principles of colloid and interface science relevant to the formation and stability of dispersions in aqueous and nonaqueous media.
- Surfactants – mechanisms, structure-property relations, selection guidelines.
- Fundamental concepts and laboratory techniques to study the chemical and physical properties of interfaces.
- Properties of emulsions and emulsifiers.
- The basic principles governing foam formation, inhibition, and antifoaming.
- Experimental methods to quantify particle size, charge, dispersion, stability, and rheological and electrokinetic properties.
- Methods to stabilize and destabilize both aqueous and nonaqueous dispersions.
