Interfacial tension hysteresis of eutectic gallium-indium

When in a pristine state, gallium and its alloys have the largest interfacial tensions of any liquid at room temperature. Nonetheless, applying as little as 0.8 V of electric potential across eutectic gallium indium (EGaIn) placed within aqueous NaOH (or other electrolyte) solution will cause the metal to behave as if its interfacial tension is near zero. The mechanism behind this phenomenon has remained poorly understood because NaOH dissolves the oxide species, making it difficult to directly measure the concentration, thickness, or chemical composition of the film that forms at the interface. In addition, the oxide layers formed are atomically-thin. Here, we present a suite of techniques which allow us to simultaneously measure both electrical and interfacial properties as a function of applied electric potential, allowing for new insights into the mechanisms which cause the dramatic liquid metal, oxidation, and interfacial tension decrease in interfacial tension.  A key discovery fr..., Data was collected using 3 techiniques: imaging of sessile drops (image processing, edge-detection), cyclic voltammetry, and electrochemical impedance spectroscopy., , # Data from: Interfacial Tension Hysteresis of Eutectic Gallium-Indium
