Researchers have built an artificial retina made of perovskite that can detect light in a similar way to the human eye. In tests, the device was even able to recognize handwritten numbers.The eyes of humans and other mammals work thanks to light-sensitive cells in the retina, rods and cones, which absorb incoming photons and send electrical signals to the brain. In this study, the researchers set out to simulate this process in a man-made device. Read More »

Can improve the damping damping performance Recently, a new type of magnesium - nickel​ - titanium bionic composite has been developed by Chinese and foreign research institutes. The composite not only realized the complementarity and combination of Nitinol and magnesium matrix in performance advantages, but also made the material have self-healing function. Read More »

Lithium ion batteries (LIB) have become the cornerstone of portable electronics, electric vehicles and alternative energy economy due to their long life, good storage performance, high energy density and high operating voltage. Improving the electrode material is the most important and feasible method to improve the electrochemical performance of LIB. Read More »

In addition, oxygen and nitrogen content also need to be strictly controlled. In aerospace and other special application fields, the purity requirements are more strict, such as the oxygen content of superalloy powder is 0.006% ~ 0.018%, titanium alloy powder is 0.007% ~ 0.013%, stainless steel powder oxygen content is 0.010% ~ 0.025% (all are mass fraction).

Among many compounds, metal borides​ have better high-temperature performance than metal carbides. For example, diboride (TiB2) cermets are better suited to high temperature and high erosion conditions than titanium carbide (TiC) and tungsten carbide (WC) cermets. Titanium diboride powder is gray (or gray-black) and ranks sixth among the ten materials with the highest melting point known in the world. Read More »

Adding rare earth metals or fluoride or silicide into steel can refine, desulphurize and neutralize harmful impurities with low melting point, and improve the processing performance of steel. Rare-earth ferrosilicon alloy and rare-earth silicon magnesium alloy are used as nodulating agents to produce rare-earth nodular cast iron. Because this nodular cast iron is especially suitable for the production of complex nodular iron parts with special requirements Read More »
