Cadmium was discovered in 1817 by Strohmeier, a professor of chemical medicine at the University of Gottingen in Germany. In 1990, FAO and the World Health Organization divided trace elements into three categories. The first category is essential to human body, there are 8 kinds, including iodine, iron, zinc, selenium, copper, molybdenum, chromium and cobalt. Read More »

As the lightest metal structure material, magnesium​ has broad application prospects in aerospace, automotive, high-speed rail, electronic products and medical and other fields. However, compared with traditional metal materials, magnesium has poor plasticity, difficult deformation processing of profiles and parts, and high process cost. This severely restricts the wide application of magnesium as a structural material. Read More »

Magnesium oxide was born in 1930s as a new material. In the early days of the founding of the People's Republic of China, due to the increasing demand of rubber products for magnesium oxide, a number of small workshop factories first emerged in Shanghai, but the production variety is relatively single. Until 1956 have developed light magnesium oxide and heavy magnesium oxide two specifications of varieties. Read More »

Titanium dioxide​ is mainly divided into three kinds: plate titanium, anatase titanium dioxide and rutile type titanium dioxide, rutile titanium dioxide, anatase titanium dioxide is two important types of titanium dioxide, currently in the market the two most widely used, but the nature of the two are very different.

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 »

Diaphragm is one of the four major components of lithium ion battery​, which plays the role of isolating the positive and negative poles, preventing the contact of the positive and negative poles from short circuit and providing channels for lithium ions to pass through. At present, in order to better match the safety and performance requirements of the power battery, the application of coated diaphragm in power battery has gradually become the mainstream.
