摘要: A technique borrowed from biology, rapid cryofixation/freeze fracture, has been adapted for the study of liquid–solid interfaces. This allows high-resolution imaging interfaces between water and substrates with varying degrees hydrophobicity. The interface gas-saturated hydrophobic surfaces is covered a network 100 nm scale features similar to those previously reported, while degassed produces smooth We thus confirm that are indeed nanobubbles which form spontaneously dissolved gas in liquid. hydrophilic surface, showing no evidence nanobubbles, not as interface.
