Photocatalysis is a new science. It uses semiconductor photocatalytic materials to obtain cheap and sustainable solar energy from nature, reduce the cost of hydrogen production and decompose various organic pollutants. It has a good application prospect in solving energy crisis and environmental pollution control.

Long afterglow materials refer to materials that can absorb and store energy irradiated by external light, and then release these energy slowly in the form of visible light at room temperature. Long afterglow material is a new type of functional material which meets the development requirements of the 21st century. It has the characteristics of high efficiency, energy saving, green and environmental protection. Its application range has also expanded from lighting, decoration to communication, display and storage.

Tungsten copper alloys have been widely used in large capacity vacuum circuit breakers and microelectronics due to their excellent properties. Tungsten and copper are mainly used in electrical materials, including electrical contact materials and electrode materials. Tungsten copper alloy sheet has been used in power electronic devices as a new type of electronic packaging material due to its small expansion coefficient and good conductivity and thermal conductivity.

Aluminum matrix composites have the advantages of low density, high tensile strength, high modulus of elasticity and high wear resistance. Therefore, aluminium matrix composites have great application potential in aviation and aeronautics.
