Tungsten particulate reinforced aluminium matrix composite is a kind of lightweight structural and functional integrated material with high temperature resistance, high strength and high wear resistance. It has great application potential and practical value, and has a wide range of applications in aviation, aerospace, automobile and electronics.

Tungsten trioxide nano-multistage structure refers to nanowires, nanorods, nanosheets and other nanostructures formed by the combination of two or more components. At present, some scholars have prepared corresponding materials by thermal evaporation, electrospinning and other processes, but these preparation methods will involve high temperature, high vacuum, high technical difficulties and other issues, which are contrary to the development of low power consumption.

It was found that tungsten-based transition metal catalysts have excellent platinum substitution function. However, the agglomeration of nanoparticles and the existence of low density active centers in the synthesis process still puzzle the synthesis of such materials.

In recent days, Intel can be said to be sitting on the needle. Since AMD released the Rzen series of processors, AMD has regained a lot of market share from Intel with its advanced multi-core architecture and excellent comprehensive performance. In the face of competitors' catch-ups and upgrades, the toothpaste factory no longer dared to squeeze toothpaste, and sacrificed many techniques at the bottom of the box.
