Noise as Data: Nucleation of Electrochemically Generated Nanobubbles.

Single-entity electrochemistry aims to expand the toolkit for probing matter at the nanometer scale. Originally focused largely on electrochemically active systems, these methods are increasingly turning into versatile probes complementary to optical, electrical, or mechanical methods. Recent studies of the nucleation, structure, and stability of gas nanobubbles, which exploit electrochemistry at nanoelectrodes as generation and stabilization mechanisms, are prototypical examples. These measurements illustrate the interplay between advances in electrochemical methods and strategies for extracting microscopic information from the results.
