Foam & Emulsion Stabilization

Research Description

Velev and his group have engineered new classes of magnetically, thermally and light-responsive foams. Earlier, the group discovered a novel shear-based method for the efficient scalable preparation of polymeric microrods that make ultrastable foams and emulsions. Historically, Velev is the first to report formation of the (later-named) “colloidosome” assemblies during his independent research in Japan.
