In the field of pollutant degradation and energy production, semiconductor photocatalysis is one of the most promising methods. In order to find efficient photocatalysts, a large number of studies have focused on the Factors Affecting Photocatalytic activity.

Recently, the "2018 China Chip Development Summit Forum" was held in Nanjing. At the meeting, Zhao Weiguo, chairman of the Ziguang Group, said: "It is estimated that in the next five years, the Chinese integrated circuit industry will basically be able to stabilize the heel."

He also said that "Chinese integrated circuits will have a place in the world by 2028 or around 2030."

What is a place?

He said, "There is one in three cents or four cents."

In this forum, Ziguang also signed the "Building 5G Industry Ecology Proposal" together with 17 manufacturers including Intel, ARM, Hisense, TCL, ZTE, Gome and Coolpad Group. This means that as the 5G is about to be commercialized, the new ecology is already accelerating brewing and formation.

I believe that you will not miss this news if you are always concerned about the IT industry. I believe that you know that the current IC industry is booming! Then you must know what the key directions of the integrated circuit industry in 2018 are?

This year, the three major areas of concern for the IC industry are artificial intelligence, memory and the Internet of Things.

Artificial intelligence is regarded as an important technology that will change the development process of human society. Of course, the artificial intelligence industry is the foundation of artificial intelligence industry. The domestic memory industry will eventually usher in a decisive moment in 2018. At the same time, the Internet of Things application will also be driven by the dual benefits of domestic consumption upgrades and industrial transformation, ushered in a new round of development climax.

When it comes to integrated circuits, I have thought of tungsten-copper composites. Moreover, in recent years, tungsten-copper composites have been widely used in large-scale integrated circuits because of their high thermal conductivity and electrical conductivity. As an electronic packaging material, the high thermal conductivity and heat resistance of the tungsten-copper composite material greatly increase the power consumption of the microelectronic device and miniaturize the device. In addition, the thermal expansion coefficient of tungsten copper makes it well matched with semiconductor materials such as silicon wafers and gallium arsenide in ceramics and ceramic materials for tubes.

Of course, the application of tungsten-copper composites can be used not only in the integrated circuit industry, but also in military defense. Because tungsten-copper composites are resistant to high temperatures, thermal shocks, and erosion, they meet the requirements of high-tech and military defense materials. Such applications generally use tungsten-copper composite materials with ω(Cu)=5%~10%. The tungsten skeleton pores have good connectivity and good capillary action to ensure that copper can be used well at high temperature. Without causing too much volatile loss.

In other words, China's IC market demand accounts for about 63% of the world's total, and is the world's largest integrated circuit market. Throughout the moment, China's IC industry continues to maintain rapid growth, and technological innovation capabilities are also constantly improving. However, China's IC industry still faces many challenges. Fortunately, there are still a lot of news of striding forward. For example, CEC China Electronics, the backbone of China's electronics industry, is also constantly transmitting news on the layout of integrated circuit projects.

The author believes that, as Zhao Weiguo, chairman of Ziguang Group, said, the arrival of the 5G era will bring huge opportunities for the development of China's integrated circuit industry, especially in recent years, such as mobile chips. I hope that in the near future, on the winding road of developing integrated circuits, Chinese enterprises can grow into giant companies.

Tungsten oxide has many symmetrical n-type semiconductor materials, such as hexagonal, cubic and so on. In particular, nano-tungsten oxide has a large specific surface area, and its volume effect, surface effect, quantum size effect and macroscopic quantum tunnel effect are significant, which makes its application areas continue to expand. It can be used as solar energy absorption materials, stealth materials, photocatalytic materials and gas sensitive materials such as NO_x, H₂S, NH₃, etc.

The tactical pen, also called the tactical self-defense pen, as its name, looks like a pen in appearance, but there are quite a lot of mystery inside. As stated on the Internet, the tungsten steel tactical pen can be described as “black technology”. It is not just an ordinary pen for daily writing. It is a multi-functional machine, such as self-defense, writing, lighting, window breaking and even Open the bottle and so on, it is not too much to describe it.

Where does the tactical pen originate?

The design of the tactical pen originated from abroad. We all know that until now, whether it is domestic or foreign, there are some controls on the self-defense equipment in law. What's more, when the tactical pen was just designed. Moreover, the original intention of the tactical pen was designed because – in American law, if it is self-defense with a knife, it is regarded as self-defense and not guilty; but if it is self-defense, it is risky and is judged to be intentionally wounded. This is because, in the United States, knives are considered a tool, and crowbars are an offensive weapon. Thus, the tactical pen is just a tool, not a weapon.

What are the components of the tungsten steel tactical pen?

Moreover, the components of the tungsten steel tactical pen are not the same. They are composed of a pen head, a pen body, a tungsten steel head, a pen cover and a survival whistle. They have a tungsten steel attack head, a self-defense knife, a refill, an emergency pen, and illumination. The lights, and even some have the function of a bottle opener.

What are the characteristics of tungsten steel tactical pens?

In terms of hardness, tungsten steel tactical pens are comparable to diamonds, with Mohs hardness of 9 or more. Of course, the tungsten steel tactical pen is not only high in hardness, but also has a series of features superior to ordinary aluminum alloy and stainless steel - wear resistance, high strength, corrosion resistance, high toughness and good weather resistance.

What can a tungsten steel tactical pen be used for?

The plot in the movie is another world that we can't match. Go back to everyday life and talk about the use of tungsten steel tactical pens. Usually, the functions of the tactical pens we often use are mainly writing and lighting. As for the close defense and emergency escape, it is an emergency application.

Apply an old saying, that is, writing and lighting are often there, close defense and emergency escape are not common! But another old saying tells us that "you can't stop the sudden coming of a disaster, but you can be prepared to deal with it at all times." That is, although it is not always a good thing, in the case of dangers and accidents, At such a critical moment, how can you not have personal protection?

As a close-fighting defense tool, in the case of outdoor distress and personal safety control, first enable the whistle function on the tungsten steel tactical pen to directly call for help. In the case of a disparity between the enemy and the enemy and highly likely to threaten life safety, consider the use of the self-defense knife function on the tactical pen.

As an emergency escape tool, it can also be said to be a tool for breaking the window. The tungsten steel tactical pen is used when the car encounters an accident such as rollover, spontaneous combustion or flood, and the door of the car is interrupted or the door is not opened. At this point, the tungsten steel tactical pen can easily crush the tempered window glass and gain some time for escape.

The application of tungsten steel tactical pen, known as "Black Technology", is not limited to this. More importantly, the subsequent development of tactical pens, especially in military applications, will not stop there.
