Dynamics of gas micronuclei formed on a flat hydrophobic surface, the predecessors of decompression bubbles

► Nucleation of gas bubbled is still enigma. ► Nanobubbles are formed on flat hydrophobic surface. ► Hydrophobic silicon wafers degassed in water and exposed to hyperbaric pressure and decompressed. ► As gas loading increased bubble density increased. ► Attraction force causes the release of a bubble at a certain volume.
