Particulate materials are adsorbed at fluid/fluid interfaces, such as oil/water and air/water interfaces, forming adsorbed films around fluid drops dispersed in another fluid. The adsorbed films can stabilize emulsions and foams by preventing liquid drops and air bubbles from coalescing each other and disproportionation. Liquids can be powderized by the particle adsorption. The material called "dry water(dry liquid)" behaves free-flowing powder but contains a large amount of water(liquid)as micromter-sized drops covered by hydrophobic(liquid-repellent)particles. This fascinating material can be utilized in many fields, for example, cosmetic, pharmaceutical, and food industries.
