Une méthode pour manipuler tension de surface du liquide par l'intermédiaire d'un métal oxydation de surface et la réduction

We present a method to control the interfacial energy of a liquid metal in an electrolyte via electrochemical deposition (or removal) of a surface oxide layer. This simple method can control the capillary behavior of gallium-based liquid metals by tuning the interfacial energy rapidly, significantly, and reversibly using modest voltages.
