Interaction between two bodies in a liquid metal is an important topic for development of metallic products with high performance. We conducted atomic force microscopy measurements and achieved the interaction between the substrate and the probe in liquid Ga of an opaque and highly viscous liquid. The interaction cannot be accessed with the normal atomic force microscopy, electron microscopy, and beam reflectometry. We performed a theoretical calculation using statistical mechanics of simple liquids by mixing an experimentally derived quantum effect. From both experiment and theory, we found an unusual behaviour in the interaction between the solvophobic substances, which has never been reported in water and ionic liquids. Shapes of the interaction curves between several solvophobic and solvophilic pairs in liquid Ga are also studied.
液态金属中两个物体之间的相互作用是开发高性能金属产品的一个重要课题。我们进行了原子力显微镜测量，并实现了在不透明且高粘性的液态镓中基底与探针之间的相互作用。这种相互作用无法通过常规的原子力显微镜、电子显微镜和光束反射法来测定。我们通过混合实验得出的量子效应，利用简单液体的统计力学进行了理论计算。从实验和理论两方面，我们发现了疏溶剂物质之间相互作用的一种异常行为，这在水和离子液体中从未有过报道。我们还研究了液态镓中几种疏溶剂和亲溶剂对之间相互作用曲线的形状。
