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 the color change process of this "electronic curtain" is gradual, you don't have to worry about the eyes being uncomfortable. What's more, when an unexpected power outage occurs, the portholes become completely transparent and comply with relevant aviation standards. At this point, some readers may ask, "So, can you easily put the Boeing 787 'magic window' home?" This just seems impossible. In fact, only need - the tungsten oxide electrochromic film black technology can give you Boeing 787 enjoy.

The tire stud on the snowy road surface includes a flange on the cylindrical nail body at the head of the core, the wing portion at the middle portion, and the lower end portion, and the wing portion and the flange form an acute angle with the nail body. When the stud is used, it is inserted into the tire tread, which is not only easy to install, but also has an anti-shedding effect. Depending on the application and the groove type, the specifications have different requirements, but the material requirements are: wear resistance, low temperature resistance, high hardness and so on.

How much more is the need for electrochromic materials to be used in large-scale commercial applications? This is a big proposition that requires us to have a certain understanding of the material before it is enough to think. So, let's take a rough look at the new materials that may be close to you and may be a little far away from you!

Nano-porous tungsten, which is characterized by large surface, numerous active spots and so on, is widely applied to a lot of fields, such as energy storage, catalysis and sensors. It can be categorized as a kind of powder metallurgy tungsten product which owns a inner structure with a lot of holes related to its application.

It is reported that graphene is gradually becoming a hot spot in the global scientific and technological community. According to experts, in addition to graphene, this two-dimensional material is gradually entering the field of science and technology.

In other words, what are the most popular words in your mind since the 21st century? Is there a place for 3D/3D? Although it is strange to separate them from specific applications, if you talk about 3D movies and 3D printing, you should not be unfamiliar. As we all know, in these areas, 3D means better visual effects, but also means higher technical level. However, for some areas, things are not like this, for example, two-dimensional materials.

It is reported that a few days ago, scientists successfully developed a 0.7nm tungsten selenide diode, which means that humans have finally broken the semiconductor 3nm process limit, and toward the development of semiconductor technology, and took a small step forward! Why do you say that? As you may be keen on semiconductors, semiconductor process technology is rapidly evolving with the development of smartphones from 28nm, 16nm, 10nm, 7nm, 5nm to 3nm. However, in this process, the miniaturization process of the semiconductor process is also slowing down due to the gradual failure of Moore's Law.

Can the tungsten copper alloy cover replace the copper type cover as the mainstream? After consulting the relevant literature, it is found that long and stable metal jet is essential to achieve the desired armor effect, and the medicinal mask material is the key to the formation of high-speed jets. Ground is the key to controlling the shape, size and quality of metal jets. Furthermore, according to the theory of penetrating fluid dynamics, the penetration depth of the metal jet is proportional to the square root of the jet length and material density. That is to say, the medicinal mask should form a longer and more stable metal jet, and the medicinal mask material should have the characteristics of high density, high sound speed and good shape.

HEAT is the abbreviation of the English "High-Explosive Anti-Tank" of the armor-piercing projectile. At the same time, most of them know that the armor-piercing projectile has another name: the hollow charge armor-piercing projectile or the gather-charged armor-piercing projectile. The chemical energy anti-armored ammunition developed based on the Monroe effect (concentration effect) is mainly used to damage armored targets such as tanks and armored vehicles. It is commonly found in tank guns, anti-tank guns, and anti-tank missiles. The hood is the "heart" of HEAT! However, in fact, the armor-type ammunition cover material is not only copper, nickel, and antimony.

Tungsten - the most refractory metal with the highest melting point. Tungsten is also an important strategic metal and is widely used in the military for its high density, high strength, high toughness, impact resistance, good shape, armor penetration and non-toxic environmental protection. Among them, tungsten alloys are used to manufacture various high-speed ammunition, especially armor-piercing projectiles, which can compete directly with depleted uranium bombs because of their extremely stable dynamic plastic deformation properties. As you may know, depleted uranium has become an environmental issue! Tungsten can also be used to protect or protect the outer casing of nuclear weapons materials. China's tungsten reserves are the world's number one!
