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
Room-temperature densification method Room-temperature densification method The room-temperature densification method was developed for LiMoO ceramics and is based on the water-solubility of LiMoO. It can be used for the fabrication of LiMoO ceramics instead of conventional thermal sintering. The method utilizes a small amount of aqueous phase formed by moistening the LiMoO powder. The densification occurs during sample pressing as the solution incorporates the pores between the powder particles and recrystallizes. The contact points of the particles provide a high pressure zone, where solubility is increased, whereas the pores act as a suitable place for the precipitation of the solution. Any residual water
