Increased porosity turns desorption to adsorption for gas bubbles near water-SiO sub(2) interface

Increased porosity turns desorption to adsorption for gas bubbles near water-SiO sub(2) interface

We consider theoretically the retarded van der Waals interaction of a small gas bubble in water with a porous SiO sub(2) surface. We predict a possible transition from repulsion to attraction as the surface is made more porous. It highlights that bubbles will interact differently with surface region...

Zusammenfassung:We consider theoretically the retarded van der Waals interaction of a small gas bubble in water with a porous SiO sub(2) surface. We predict a possible transition from repulsion to attraction as the surface is made more porous. It highlights that bubbles will interact differently with surface regions with different porosity (i.e., with different optical properties).
