At present, tungsten oxide has been widely used in chemical sensors, optoelectronic devices, fuel cells and other fields. It is a new hot spot in the research of nano-metal oxides. However, the current domestic research on nano-tungsten oxide materials is mainly concentrated in the two advantageous areas of electrochromic and gas sensors. There are few studies on the photocatalytic and photochromic properties of tungsten oxide, especially for sol-gel preparation. The research on photochromic tungsten oxide is rarely reported in China.…

Scientists have identified a class of materials that could prospectively be used for developing even higher power batteries. The team, from the University of Cambridge, used materials that had a complex crystalline structure and discovered that lithium ions pass through them at rates far exceeding those of conventional electrode materials, which translates into a battery that charges considerably faster. Such materials, called niobium tungsten oxides, do not lead to higher energy densities upon being used under typical cycling rates. However,…

Recently, “the strongest brain” Central South University and the “shield giant” iron construction heavy industry marriage. What kind of spark will this shine? What kind of story will be created? It is bound to create an “iron-tooth steel tooth” that exerts the best performance of “Pangolin”! At this time, friends may ask: Is this “Pangolin” awkward? What is the “iron tooth steel tooth”? In fact, this is the main body of the “Pangolin” name is the shield machine! Then, what…

CCTV’s first large-scale popular science program broadcasts a section on the contents of China’s tank armor-piercing projectiles: China’s 59-type tank armor-piercing projectile instantly penetrates ten layers of steel plates, with a total wear depth of 1500mm. Therefore, for the most advanced 99A tanks in China, which are superior to the performance of the 59-2 tank, if it is a 125mm tungsten alloy armor-piercing projectile, the piercing depth should be greater than 1500mm. Military experts said that China’s strength in the…

A warship can carry thousands of tungsten alloy bombs, and its combat performance is comparable to that of medium-range missiles? This is sourced and will be discussed later. Presumably, the artisans should know that the United States regards the electromagnetic orbital gun as a subversive weapon capable of changing the rules of the war game. It is estimated that such a legend of the rivers and lakes, the US Navy has already put the electromagnetic railgun into the “cold palace”,…

According to experts, in the near future, tungsten oxide electrochromic glass can easily achieve warm winter and cool summer! It is said that this is a black technology achievement! Just press the power switch lightly to make the glass “discolor” instantly, from transparent to dark blue. Ordinary glass does not have thermal insulation, and this black technology can make the glass block most of the sunlight in the hot summer, reduce the indoor temperature, thus reducing air conditioning costs and…

The case of the girl in Yueqing, Zhejiang Province, who was killed by the drip and the wind, has aroused the attention of people from all walks of life. The occurrence of this case also reminded people of the Zhengzhou flight attendant’s car murder case three months ago. For a time, the voice of the question about the Drip Trip platform on the Internet was soaring. This also sounded the alarm of self-protection for the majority of female friends! We…

Recently, it was reported that a child in the Xiaolan station of the Guangzhou-Zhuhai intercity had not paid attention to drilling into the security inspection machine. The security personnel who saw this situation immediately stopped after the discovery and directed the child to climb out from the exit. According to reports, in addition to the “bear children”, there have been adults who climbed into the security inspection machine for various reasons and “frightened” many security personnel. At the beginning of…

The Boeing 787 “dream window” does not have a visor, but it can change the transparency, and the effect of this is the same – tungsten oxide electrochromic film. The porthole of the Boeing 787 has no visor, but it can change the transparency! You only need to press the button; the porthole will become a “chameleon” until it is completely darkened! Of course, the captain can also dim directly from the cockpit when the night falls. In addition, because…
