Dispersion in Liquids: Suspensions, Emulsions, and Foams
Ian Morrison, Instructor
Thursday and Friday, April 30-May 1, 2009
Mason Business Center – The Procter & Gamble Company
8700 Mason-Montgomery Road, Mason Ohio
Why Attend?
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. 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.
Key Topics You’ll Learn About
- 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.
How You’ll Benefit from This Course
- Consult with a seasoned expert about your R&D problems.
- Gain a valuable understanding of relevant techniques.
- Become proficient at relating observable dispersion properties to fundamental causes.
- Develop an industrial approach to this subject by examining and discussing practical examples.
- Take the opportunity to discuss with the instructor your own related problems.
- Become familiar with the terminology of the field.
- Be exposed to the latest techniques to produce and characterize dispersions, emulsions, nanoparticles.
