Applied Fundamentals in Interfacial Phenomena

Saturday • April 27, 2013

Attendees learned to solve colloidal foam and dispersion problems with this short course.  Topics discussed include the technology of surfactants, the role of surface tension forces, the control of stability, and useful technologies for formulation and measurement techniques of emulsions, foams, and dispersions.

Attendees: Scientists and engineers in research and development in the chemical, petroleum, coatings, food, pharmaceutical, cosmetics, and ceramics industries.

Instructor:  Ian Morrison, Applied Physics Department, Harvard University, USA. Morrison has been a lecturer in Applied Physics at Harvard since 2008. Previously he was a Fellow at Cabot Corporation, Director of Ink Technology at E Ink Corporation, and a Principal Scientist at Xerox Corporation. He has 25 years of experience as lecturer for short courses in the field of colloid science.
