Cutting-Edge Science Projects

In such an environment, the movement of electrons seems to have broken free from the constraints of conventional physical laws and presents a new state. The two main characteristics of low-temperature superconductivity are zero resistance and complete anti-magnetism. When a material reaches a superconducting state, its resistance suddenly drops to zero, which means that current can flow through it without loss. This feature has great application potential in fields such as power transmission and magnetic separation. Complete anti-magnetism means that superconducting materials can shield the influence of external magnetic fields. This feature has been widely used in medical equipment such as magnetic resonance imaging (MRI).
If you encounter low-temperature materials such as liquid nitrogen (about minus 196 degrees Celsius) in your life, remember to control your curiosity. Don't use it to freeze ice cream and eat it directly, because it will be worse than licking the iron door at minus dozens of degrees. Well, don't ask me how I know.
Low-temperature superconductivity and our low-temperature superconductivity phenomenon were first discovered by foreigners, when China was still in dire straits. In 1911, Dutch physicist Kavelin Onnes accidentally discovered in an experiment that when mercury was cooled to a temperature close to absolute zero, its resistance would suddenly disappear. This discovery attracted widespread attention in the scientific community and opened the prelude to low-temperature superconductivity research. Subsequently, scientists have discovered more materials with superconducting properties. These scientific discoveries, combined with research on technical engineering applications, have led to the practical application of low-temperature superconductivity.
Nowadays, our Chinese science and technology is changing with each passing day and booming. There are many Chinese companies like our Xinli Superconducting that are committed to the low-temperature superconductivity industry, building national brands, and working hard for our new generation to look at the world at eye level or even overlooking it.
With the in-depth study of the low-temperature superconductivity phenomenon, its application areas are gradually expanding. In the field of medical equipment, superconducting magnets can be used in high-end medical equipment such as MRI to provide doctors with more accurate diagnosis basis. In the field of mineral processing, the field strength that superconducting magnets can achieve is much higher than that of ordinary electromagnetic magnets. In addition, low-temperature superconducting technology also has broad application prospects in the fields of particle accelerators, nuclear fusion reactors, and maglev trains.

The content of helium in the earth's crust is extremely small (because its density is very small, it cannot be bound under the gravity of the earth, and finally all runs into the universe). Helium has a very low solubility and is almost insoluble in water. Therefore, the way for humans to obtain helium is to mine the helium sealed in the earth's crust, and this helium is mainly released after the decay of radioactive substances. Helium is mainly used as a protective gas, working fluid for air-cooled nuclear reactors, and ultra-low temperature refrigerant. It is widely used in military industry, scientific research, petrochemicals, refrigeration, medical treatment, semiconductors, pipeline leak detection, superconducting experiments, metal manufacturing, deep-sea diving, high-precision welding, optoelectronic product production, etc.

Helium is definitely a strategic resource for military industry! Wherever the next generation of superconducting technology is applied, liquid helium resources must be applied. Not only that, but also aircraft carrier electromagnetic catapults, electromagnetic railguns and other products need to use helium resources. As an inert gas, many of the commonly used phased array radar antenna units are filled with helium, which is used to protect the medium of these sensitive electronic components. Even hard disks for high-density storage are filled with helium.

Helium is also a necessary gas for welding, especially for welding pure aluminum or aluminum alloys. A mixture of helium + argon must be used to ensure the integrity of the weld. It is generally used in our common warships and civilian high-speed railways. In addition, future laser weapons are also using helium as a protective gas, etc.
