is still an open question, and at least some experimental observations cannot be explained: the stability of bulk nanobubbles at low gas saturation, as well as the stable nanobubbles reported experimentally having a typical size around ~100 nm. Our previous work demonstrated through molecular dynamics simulations that bulk can be stabilized by forming a compressed amphiphile monolayer at bubble interfaces. This observation closely resembles stability of microemulsions. This similarity inspires us to explore the stability theory for bulk nanobubbles, in analogy with microemulsions.
