报告摘要：
Room-temperature liquid metals have a number of interesting surface and bulk properties that make them intriguing for scientific explorations and a variety of industrial applications. Co-alloying other elements into the gallium is shown to dramatically change the physical and chemical properties of liquid metals and the unique properties arising from different alloys set promising pathways for developing future technologies. As such, gallium-based eutectic alloys such as EGaIn (containing gallium and indium) and galinstan (containing gallium, indium, and tin) are liquid at room temperature, are nontoxic, and feature metallic bonds. The surface properties of gallium liquid metal alloys can be manipulated by selecting appropriate alloying elements on the basis of the Gibbs free energy of reaction. The surface is found to consist of atomically thin functional materials for emerging applications in microfluidics, 3D printing, flexible and stretchable electronics, piezotronics and electrochemical systems.
