Surface nanobubbles are nanoscopic gaseous domains on immersed substrates, which can survive for days. They are not only interesting from a fundamental point of view, as the flow and the mass transfer on a nanoscale have macroscopic consequences, but they also have major application potential, e.g., in flotation, for transport in nanofluidic devices, in (photo) catalysis, and in nanomaterial engineering. The presence of surface nanobubbles and nanodroplets has implications for various interfacial properties and phenomena and thus is relevant for all applications where these properties matter. For more details we refer to our recent Rev. Mod. Phys. article on surface nanobubbles and nanodroplets. We have divided this project into two parts: (i) the stability of gaseous surface nanobubbles and simulation of nanodrops on solid surfaces to characterize the wetting phenomena on chemically and physically heterogeneous surfaces (ii) Dissolution of surface nanodrops in another liquid.
