Dispersions in Liquids: Suspensions, Emulsions, and Foams

Learn how to solve your colloidal, foam, and dispersion problems in two days.

About the Course

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.

Consult with a seasoned expert about your R&D problems. Topics covered will include 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.

Special Notes:
Registrants are encouraged to purchase a copy of the book Colloidal Dispersions: Suspensions, Emulsions, and Foams by Ian Morrison and Sydney Ross in addition to their registration as part of this course.

What You Will Learn

  • Terminology of the field
