How bulk nanobubbles might survive
Web1 de jun. de 2024 · Surface nanobubbles survive the removal of as much as 80% of the dissolved gas in the bulk liquid [ 20 ]. This is remarkable because the Epstein–Plesset theory predicts that spherical gas bubbles must dissolve immediately once the dissolved gas concentration falls below exact saturation. WebThe existence of bulk nanobubbles has long been regarded with scepticism, due to the limitations of experimental techniques and the widespread assumption that spherical …
