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…

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…

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…

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…

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…

Recently, a world-made and tungsten carbide propeller made of the world’s first polar condensate tank with a capacity of 44,500 tons appeared in Nansha. Give it a name first – “BORIS SOKOLOV”. Then, the shipowner – the Greek company. Then, it should be put into operation, and invested in a project known as “a pearl of energy embedded in the Arctic Circle”. Specifically, the vessel, designed according to the Russian Ice Society’s highest ice zone level, Arc7 icebreaking capacity, will…

In recent years, China’s defense industry has undergone earth-shaking changes, rapid development in technology and technology, and has also been freed from financial constraints. Not only that, but also achieved remarkable achievements – China has established a defense industry system that can independently develop high-tech weapons platforms, and has basically achieved self-sufficiency. Among them, advanced stealth fighters (殲-20, 殲-31), aircraft carriers (002 domestic aircraft carriers under construction, third, fourth…), stealth drones (Pterosaur-2, etc.) and new Cutting-edge weapons such as a…
