Tuesday, November 14, 2006: 3:15 PM-5:45 PM
Union Square 25 (Hilton San Francisco)
#271 - Colloidal Dispersion III - Structure & Rheology (01C10)
These sessions will consider colloidal dispersions, including dispersions of solids in liquids, emulsions, and foams. Presentations of either an experimental or theoretical nature are welcome on issues relating to responsive or functional colloids; colloidal crystals, gels and glasses; adsorption at interfaces; and colloidal interactions. Contributions are also welcome on other topics relating to the properties or applications of colloids.
