British media claimed that scientists have achieved a great breakthrough in radio signal conversion into electricity. It is possible that we will soon see mobile phones with no battery and portable laptops without batteries. MoS2 is a brand new, two-dimensional materials and one of most thinnest in the world. It exhibits semiconductor and photoelectricity. A …
What’s tungsten oxide? Tungstenoxide has a molecular composition of WO3 and an molecular weight 2318.55. It is a product of the tungstic anhydride. It includes tungsten dioxide as well as the tungsten anhydride. There are currently no tungsten products in industrial production. There are five types of tungsten-trioxide salts: tungstic, sodium, calcium, tungstates, ammonium partungstates, …
What metal can resist higher temperatures than that of tungsten, and why? The most melting metal element on the periodic tree is tungsten. Its 3,422-degree boiling point (boiling temperature 5,930) makes it the number one. Because of its high bond energy, tungsten melts at a much higher temperature than any other metal element. Tungsten (elem. …
What is Boron Netride? Boron, nitride is a compound that was developed more than 100-years ago. For high-temperature applications, hexagonalboron nutride was the first to be used. Although hBN’s structure is identical to graphite, its performance and appearance are similar. It is also known as white graphite. Boron is composed of two atoms: a nitrogen …
Hafnium boridide is a gray metallic, shiny crystal. The melting point for hafnium boride at 3250 is high. Also it has an excellent electrical conductivity. A room temperature reaction with hafnium boreide, save for HF, is not possible. The preparation involves heating rhenium dioxide with boron carbide/boronoxide and carbon, then mixing the two together. It …
Polyester powder printing by SLS Nylon sintering uses spread powder stick. Once one section has been sintered, the control systems to adjust the laser beam according the contour scanning of powder. After that, the laying roll lays another layer of dense, uniform powder onto it. Material: nylon/nylon and fiber SLM-metal 3D printing Metal sintering involves …
Nano colloidal gold is a metallic element made of silver with a particle dimension between 1 and 100 nanometers. While the majority of nanosilver has a particle size around 20nm and some can go as low at 5nm, most have a smaller diameter. This broad-spectrum antibacterial effect on bacteria is known as colloidal Silver. The …
Molybdenum is made up of molybdenum and disulfide. It is a gray-black solid powder. It has an odorless feel and slippery feeling. It falls under the hexagonal and orthorhombic groups, is very similar graphite-like in texture, and also has metallic luster. Molybdenum sulfide is an important solid lubricant. It’s used in automotive, aerospace (vacuum ray …
Diamond and cubic Boron Nitride are the most popular superhard material. The hardest material known is diamond. This includes both synthetic diamond and natural diamond. South Africa, Zaire and many other countries are home to the majority of primary diamond ores. China and India contain a very small quantity of placer-ores. Artificial diamond is created …
