Highly stable foams by the attachment of silica nanoparticles to bubble surfaces

23-Jun-2005 - Foams are gas bubbles confined by fluid or solid boundaries. Whereas solid foams are quite stable, most fluid foams quickly collapse. To stabilize foams, surface-active reagents or proteins are generally used. British researchers have developed foam stabilizers that are more effective: highly ...
