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 is removed by post-processing typically at 120 °C. The method is suitable also for LiMoO composite ceramics with up to 30 volume-% of filler material, enabling the optimization of the dielectric properties. 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.
