and formed spontaneously and instantaneously upon exposure to atmospheric oxygen. [1-3] The thin film or "protective skin" covering the surface of RTLMs, generally dominated the physical properties and applications of the materials. This thin film is composed of a majority fraction of gallium oxides with a much smaller amount of indium and tin oxides. [4] When immersed in acidic or alkaline electrolytes, the oxidic films of RTLMs will be dissolved. [5-8] Due to the disorder of internal structure, the surface of the spherical liquid metal droplet is smooth and removable under the function of surface tension. [9,10] According to the size and structure of the solid substrate, the contact areas between the liquid metal and the solid substrate shows various wetting phenomena and corresponding application scenarios. [11-14] Surface chemical composition plays the primary role in dominating various phenomena and practical applications of RTLMs, which possessed the technologically important and scientifically interesting parameter. Gallium-based liquid metal is similar in structure to conventional solid metal, except for some covalent bonds inside, and the physicochemical properties have the commonality of both metallic solid and fluid properties. [15] The composition of gallium-based alloys can be assumed as made up of several atomic groups, within which the permutation of the solid remains, the binding energy between the liquid atoms remains strong, but the binding force between the groups was broken. The interface refers to the contact area between the different phases, which is the transition layer from one phase to another. The binding force of electrons that are relatively far away from the inner core is related to their energy, causing the interface behavior between different phases to be incompletely consistent. The surface is a type of interface, which specifically refers to the gas phase substance in interfacial behavior. In the processes of thermodynamics, [16,17] surface absorption, [18,19] controllable wetting, [6,13,20] material catalysis, [21,22] redox, and other physical and chemical reactions, [23,24] RTLMs inevitably contact with other substances with different phase states. Even the pure liquid metal would contact with oxygen in the air to yield a thin protective film. [17,25,26] Therefore, the investigation of interfacial behaviors between RTLMs and different surrounding mediums is helpful to renovate and broaden the understanding and applications of liquid metal. So far, there gradually appeared literature on phenomena and mechanism of the interfacial effect of RTLMs, such as synthesis of low-dimensional materials in the gas atmosphere, [27,28] Room temperature liquid metals (RTLMs), especially those made of galliumbased alloys belong to an emerging versatile material with fascinating characteristics derived from its simultaneous metallic and inherent fluidic natures. The interfacial effects of liquid metal involved in diverse surfaces thus play critical roles in explaining many fundamental phenomena....

Molten metallic nanoparticles have recently been used to construct graphene nanostructures with crystallographic edges. The mechanism by which this happens, however, remains unclear. Here, we present a simple model that explains how a droplet can etch graphene. Two factors possibly contribute to this process: a difference between the equilibrium wettability of graphene and the substrate that supports it, or the large surface energy associated with the graphene edge. We calculate the etching velocities due to either of these factors and make testable predictions for evaluating the significance of each in graphene etching. This model is general and can be applied to other materials systems as well.As an example, we show how our model can be used to extend a current theory of droplet motion on binary semiconductor surfaces.
