Ben-Gurion University in the Negev, Israel is developing a new type of self-disinfecting and purifying air filter based on graphene water filtration technology.
Li3N is lithium nitride, which is a metal nitrogen compound that is a purple or red crystalline solid, showing a light green luster under reflected light and a ruby color in transmitted light.
Titanium dioxide is an essential white pigment and porcelain glaze. They are used in paint, ink, plastic, rubber, papermaking, chemical fiber, watercolor paint, and other industries. T
The chemical nature of nitrogen is very stable, but under some special conditions, it can form nitrides with many elements. In these nitrides, the transition metal nitride-titanium nitride (TiN) has become the focus of research.
Metal borides are hard compounds formed by transition metals and boron. The crystal structure of boride is determined by the structural characteristics of boron atoms. The chemical stability of the boride is gradually decreased in the order of IVA to VIA.
Silicon carbide was a carbide that was accidentally found in the laboratory by American Acheson in the fused diamond experiment in 1891. At that time, it was mistaken for a mixture of diamonds, so it was named emery. Acheson developed it in 1893.
