Heterogeneous cavitation from atomically smooth liquid–liquid interfaces

Pressure reduction in liquids may result vaporization and bubble formation—a process known as cavitation. It is commonly observed hydraulic machinery, ship propellers even the context of medical therapy within human body. Although cavitation be beneficial for removal malign tissue, many cases it unwanted due to its ability erode nearly any material close contact. The current understanding that origins heterogeneous are nucleation sites where stable gas cavities reside, example, on contaminant particles, submerged surfaces or shell-stabilized microscopic bubbles1,2. Here we present discovery an atomically smooth interface between two immiscible acting a site. non-polar liquid has higher solubility and, upon pressure reduction, acts reservoir accumulates at interface. We describe experiments reveal formation droplets contact with water, elucidate working mechanism leads pockets through simulations. Cavitation refers emergence bubbles from undergoing reduction. A hitherto unknown scenario now reported, originating liquids.
