Depleted uranium composites are the most excellent penetrating core materials due to their excellent self-sharpness. In the early 1990s, based on the international public opinion and environmental pressure caused by the toxicity of depleted uranium materials, the United States began to develop an alternative uranium armor piercing core. material. On the basis of the tungsten-nickel-iron heavy alloy, the researchers designed a tungsten-based heavy alloy armor-piercing projectile through the change of the microstructure of the alloy, but there is still a big gap between the self-sharpening effect of the depleted uranium alloy.

As a high-tech industry in the 21st century, the rapid development of semiconductor industry has far exceeded the traditional iron and steel industry and automobile industry. Silicon material is the cornerstone of semiconductor industry, but with the increasing integration, the shrinkage of size will mainly lead to leakage and static power density of devices. Recently, transition metal chalcogenides, especially tungsten disulfide and molybdenum disulfide, have attracted much attention in the scientific community due to their excellent electrical, optical and mechanical properties, as well as graphene, as a potential post-silica material.


Nanocrystalline Tungsten Trioxide Electrochromic Energy Storage Film


Electrochromic means that the optical properties of materials change reversibly under the action of an applied electric field. The color and optical transmittance of electrochromic materials can be changed at low voltage, and the fading state of electrochromic materials can be maintained under open circuit condition. With this characteristic, electrochromic devices are widely used in energy saving, optical regulation and other fields. Wisdom window is one of its most representative applications.

Mining industry, as the pillar of our national economy, consumes a lot of water resources every year. At the same time, flotation treatment also produces a large number of flotation wastewater. Among them, sulfide flotation produces a large number of wastewater containing xanthate, xanthate is the most effective and widely used collector in sulfide flotation. Most xanthate will enter the foam product with the end of flotation. If residual xanthate is discharged directly without treatment, it will cause great harm to the environment.
