It is not clear to me whether all nanobubbles are assumed to be in water; sometimes other liquids are mentioned, but whether as the body or the contents of a bubble is not defined. I wonder if there is any similarity to defects or vacancies in solid metals. Water does have an extended hydrogen-bonded structure. | |

Obviously there should not be vacuum, so either liquid vapors, or air /gases bubbled inside (unless one think of a robust cage extra resistant to inwards collapse, but how could they form at first?) | |
| Apr 2, 2021 at 13:29 | comment | added | James Gaidis | @Ivan: my ignorance about nanobubbles concerns the distinction between ordinary bubbles, whose behavior is reasonably well understood, and this new (?) class of bubbles, which is claimed to be so different. This resembles "nascent" hydrogen, etc., which isn't really thought of anymore. Maybe there is some connection. But I'm wondering about freely suspended bubbles. | |
