摘要

As predicted by classical macroscopic theory, the lifetime for nanoscale gas bub-bles is extremely short. However, stable gas nanobubbles have been experlmen-tally 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 Umescale for experl-mental observations.
