Giant and switchable surface activity of liquid metal via surface oxidation
Proceedings of the National Academy of Sciences, 111(39), 14047–14051.
author keywords: EGaIn; electrocapillarity; electrorheology; dewetting; spreading
TL;DR:
This work suggests that the wetting properties of surface oxides—which are ubiquitous on most metals and semiconductors—are intrinsic “surfactants” that can be harnessed to induce previously unidentified electrohydrodynamic phenomena for manipulating liquid metal alloys based on gallium.
