Recently, researchers at the University of Science and Technology of Taiwan successfully fabricated a nanofiber membrane, a purple tungsten oxide/polylactic acid fiber membrane (WWO2.72/PLA), through a novel nanometer to submicron ultrafine fiber processing method. We all know that solar energy is a clean energy source, and it is inexhaustible. According to statistics, the energy consumption in the world for one year is only equivalent to the solar energy that hits the earth on a day. In other words, sunlight provides…

We all know that from a rational point of view, tungsten carbide ring can be used as decorations; from a perceptual point of view, tungsten carbide ring is not just decorations, because it can add a bit of personality and fashion sense to the trend. Not only that, the specially designed tungsten carbide ring can also be used for self-defense. Moreover, this hard, diamond-like ring can also be used to break the window and escape. In the end, the “black…

According to the news released by the Ministry of National Defense of the People’s Republic of China, the Russian “Oriental-2018” strategic exercise that was invited to participate in this military is the largest strategic exercise organized by the Russian military in recent years. This time is also the largest outbound performance in the history of our military. Our army has a military force of about 3,200 troops, and has invested more than 1,000 vehicles including 99 tanks, 30 fixed-wing aircraft…

Recently, materials science researchers from Xi’an Jiaotong University, together with Southern University of Science and Technology and Pennsylvania State University, have designed a new electrochromic device with ionohydrogel with novel electrochromic layered structure. The research results have been published in the well-known journal “Materials Horizons” in the field of international materials. This research paper is entitled “Multidingal Hydrogel Enables Extremely Simplified Electrochromic Devices for Smart Windows and Ionic Writing Boards”. The research was supported by the National Natural Science Foundation,…

You may know that Victoria is located on the southeast coast of Australia and is known as the “Garden State” and the “Australian Miniature”! However, you know that although the state is only three percent of Australia’s land area, its GDP is more than a quarter of Australia’s. It has to be said that part of the credit is its rich natural mineral resources, which provides a good foundation for the development of the Australian economy. Therefore, Australia can be…

A few days ago, the Chinese private rocket, the “hyperbolic Z” rocket, was the first sub-orbital test. This is not the first time launch a space launch. In the earlier, another private company also successfully conducted a sounding rocket test, the first private commercial rocket in China. However, what do you know about tungsten copper throat inserts while knowing these messages? Whether the tungsten copper throat inserts help Chinese private rockets lift off? We all know that the working environment…
