Metal aesthetics of metallic jewelry. Some metals have specialized uses; mercury is a liquid at room temperature and is used in switches to complete a circuit when it flows over the switch contacts. Radioactive metals such as uranium and plutonium are used in nuclear power plants to produce energy via nuclear fission. Shape memory alloys are used for applications such as pipes, fasteners and vascular stents. Metals can be doped with foreign molecules—organic, inorganic, biological and polymers. This doping entails the metal with new properties that are induced by the guest molecules. Applications in catalysis, medicine, electrochemical cells, corrosion and more
Liquid metal can move in free space and in various structural channels; surprisingly, it can also make its own deformation adjustment according to the width of the path along the path. The dynamic mechanism comes from two aspects. According to Rebinder's effect , liquid metal alloy EGaIn or Galinstan would penetrate into aluminum, destroying the oxide skin on Al surface and leading to the activation of Al. In NaOH solution, Al is the cathode and liquid metal works as the anode. the dissolution of Al on the cathode renders Al to lose electrons, Under the equilibrium state, gallium reacts with the alkali
