Long lifetime of nanobubbles due to high inner density

Abstract: As predicted by classical macroscopic theory, the lifetime for nanoscale gas bubbles is extremely short. However, stable gas nanobubbles have been experimentally observed in recent years. In this report, we theoretically show that, if the inner density of gas bubbles is sufficiently high, the lifetime of nanobubbles can increase by at least 4 orders of magnitude, and even approaches the timescale for experimental observations. nanobubble, stability, long lifetime, inner density Interfaces of solid surfaces aga… Show more

“…The productiono fs olution exchange by degassedw ater and degassed ethanol were also tested. [4,37] Figure1a-d shows typical scattering faculae, in which the numbers of faculae indicate the numbers of bulk nanobubbles produced by E-W exchange, as obtained by the high-speed camera of Nano-Sight.…”

“…The lifetime of most generated bulk nanobubbles is usually about 4.5 h, and thus, bulk nanobubbles are less stable than surfacen anobubbles, which last for several days. [4,37]…”

“…Several hypotheses have been proposed to explain the surprisingly long lifetime of surface nanobubbles [14,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. * k.yasui@aist.go.jp One explanation is that the gas-water interface of a nanobubble is shielded by a layer of impermeable contamination [19].…”

“…Earlier work mainly focused on the influences of dispersed gas molecules dissolved in water on biomolecules. The recent experimental and theoretical studies demonstrated that gas can be aggregated at the water-solid interface in the form of nanobubbles89101112131415161718 and nanopancakes1920 after the great debate212223. Thus, the interaction between aggregated gas molecules, as opposed to dispersed gas molecules, and biological macromolecules is an important area of investigation.…”
