Stabilization of nanobubbles under hydrophobic confinement

, 2019
It has been recently shown that nanobubbles exhibit a remarkable and unexpected stability. The lifetime of nanobubbles, formed either within liquids or on hydrophobic surfaces, can exceed by more than 10 orders of magnitude the theoretical expectation ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Long-lived submicrometric bubbles in very diluted alkali halide water solutions

, 2012
Solutions of LiCl and of NaCl in ultrapure water were studied through Rayleigh/Brillouin scattering as a function of the concentration (molarity, M) of dissolved salt from 0.2M to extremely low concentration (2.10^-17 M ).

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.
