Microbubble dynamics

Electrolyte type affects electrochemical bubble formation

Nature Chemistry volume 15, pages 1488–1489 (2023)Cite this article

Subjects

Gas bubble accumulation at interfaces is a barrier to achieving more efficient electrochemical devices. A clever model system to understand bubble formation during electrochemical hydrogen evolution now reveals similarities between the forces at play during their detachment from the catalyst surface and those involved in wine climbing up a glass.
