Discovery of a new liquid-liquid interfacial deformation by partial miscibility
(PHYSorg.com Physics)

The international collaborative team of Tokyo University of Agriculture and Technology (TUAT, Japan), IIT Ropar (India), Osaka Univ. (Japan) has discovered that `partially miscibility,` in which two liquids do not mix completely with finite solubility, is capable of deforming the liquid-liquid interface. This interfacial deformation originates due to the spontaneous motion driven by phase separation between the soluble species, and is a phenomenon that cannot be seen with completely mixed (fully miscible) with infinite solubility or (almost) immiscible with no solubility.
