Surface nanobubbles and micropancakes [PDF]
Journal of Physics: Condensed Matter, 2013 When looking at a wetted surface with a technique that can probe the nanoscale, a high surface coverage of gas bubbles is often revealed. So what? Well, if we believe in classical diffusion, these bubbles should dissolve in microseconds, but in reality they are found to remain stable for as long as anyone has observed (five days thus far, which is 10 ...

Mechanozyme: An Artificial Enzyme With a Mechanophore Framework
Advanced Science, EarlyView.Mechanical destabilization of a G‐quadruplex mechanophore in a DNAzyme markedly boosts its catalytic activity, demonstrating “mechanozymes” as artificial enzymes whose functions are modulated by mechanical stress exerted by ultrasonication. This mechanozyme principle is broadly applicable to control biomolecular activities.

Stability, dynamics, and tolerance to undersaturation of surface nanobubbles
, 2019 The theoretical understanding of surface nanobubbles—nanoscale gaseous domains on immersed substrates—revolves around two contrasting perspectives. One perspective, which considers gas transport in the nanobubbles’ vicinity, explains numerous stability ...
