(223a) Oil-Coated Bubbles in Aqueous Suspensions

The interaction of water-borne particles with oil-coated bubbles is not a common occurrence, but it is key to a number of fascinating phenomena with great potential for application in the development of new materials and processes. To support this claim, my presentation will discuss three relevant scenarios: the particle-induced dynamic reconfiguration of bubble-droplet morphologies, the removal of hydrophilic particles from aqueous slurries by oily bubble flotation, and the formation of capillary foams, a promising new class of foam materials with unique rheological behavior.
