论文摘要
了解液态金属中两个物体之间的相互作用对于开发具有较高刚度，强度，可塑性和热稳定性的金属很重要。我们在液体GA中进行了原子力显微镜测量，并进行了理论计算，其中使用了含有量子效应的简单液体的统计力学。实验和理论表明，液态金属中探针与底物之间的相互作用中的异常行为。在相互作用中，存在相对较多的振荡和较大的振幅。此外，相互作用范围相对较长。从理论计算中，我们发现了一种不对称特性，即当探针是溶采液并且底物为溶v的时，相互作用往往是令人反感的。当交换溶剂化亲和力时，相互作用在接近位置往往会吸引人。我们的发现将有助于理解和控制纳米颗粒的分散稳定性以及液体金属中的化学反应。
Understanding the interaction between two bodies in a liquid metal is important for developing metals with high stiffness, strength, plasticity, and thermal stability. We conducted atomic force microscopy measurements in liquid Ga and performed a theoretical calculation in which the statistical mechanics of a simple liquid containing a quantum effect was used. The experiment and theory showed unusual behaviours in the interactions between the probe and substrate in the liquid metal. In the interactions, there were relatively numerous oscillations and large amplitudes. Furthermore, the interaction ranges were relatively long. From the theoretical calculations, we found an asymmetric property that when the probe is solvophilic and the substrate is solvophobic, the interaction tends to be repulsive; when the solvation affinities are exchanged, the interaction tends to be attractive in the close position. Our findings will be useful for understanding and controlling dispersion stabilities of nanoparticles and chemical reactions in liquid metals.
