The Science Fiction World of Xueba

Pang Xuelin picked up the phone, the caller ID was Cao Yuan, and Pang Xuelin directly pressed the answer button.

"Hey, Lao Cao, what's the matter?"

"Professor Pang, it worked!"

"Successful?!"

Pang Xuelin was slightly taken aback, and his voice suddenly became louder.

Since the last successful construction of a unified superconducting theory at the University of Science and Technology of China, Cao Yuan led Zhou Tong and the others to Qiantang Laboratory, and cooperated with Li Changqing's team to prepare multi-walled carbon nanotube materials that meet high-temperature superconducting conditions according to Pang Xuelin's theory .

But it's not an easy task.

Although Pang Xuelin and Li Changqing's team worked together before, using a computer-controlled reaction black box, the legendary flying blade material was prepared and industrialized production was realized.

However, the monomer of the flying blade material is a single-walled carbon nanotube.

In the field of multi-walled carbon nanotubes, it is even more difficult to prepare high-purity ultra-long multi-walled carbon nanotubes than flying edge materials.

After all, single-walled carbon nanotubes are just single-layer carbon tubes, and the best thing to do is to control the diameter of the tubes during preparation, while multi-walled carbon nanotubes are composed of multilayer carbon nanotubes. In addition to the tube diameter, you must also consider The distance between different carbon layers, structure, chirality and other factors.

As for the preparation of the multi-walled carbon nanotubes calculated by Pang Xuelin's theory, there are more factors to be considered.

Pang Xuelin was even prepared to spend three to five years. He never thought that after only a few months, Cao Yuan's team and Li Changqing's team completed the preparation of this room temperature superconducting material.

No matter how you look at it, this is an extremely amazing achievement.

Cao Yuan on the other end of the phone was still a little excited, and said: "The trial production of the sample was completed last night, and we started testing this morning. Until now, we can basically confirm that the superconducting transition temperature of this superconductor is about 353K (80°C). The performance is very different, and we have successfully prepared a room temperature superconductor!"

Pang Xuelin pondered for a moment, then said: "I'm at Jiang University now, wait until I get to the laboratory, and I'll talk about the rest when I get there."

"good!"

After hanging up the phone, Pang Xuelin found that Xu Xincheng and Liu Tingbo were staring at him, perhaps because his tone was exaggerated just now.

Xu Xincheng asked curiously, "Professor Pang, what's the matter? Did Qiantang Lab produce any new results?"

Pang Xuelin nodded with a smile, and said: "It has been achieved! But this matter is more important. I have to go to confirm it now. If there is no problem, this achievement should not be much worse than lithium-air batteries, and even more significant!"

"Not much worse than lithium-air batteries?!"

"It's more meaningful?!"

Xu Xincheng and Liu Tingbo looked at each other, a little in disbelief.

You should know that lithium-air batteries have been used in mobile phones, tablet computers, notebooks, automobiles, drones, submarines, and even new-generation airliners and transport aircraft since they were launched last year.

The political effects caused by this product directly shattered the United States' dream of containing China's development through a trade war, and even made the Western countries' technological blockade against China a waste of paper.

The economic effects of lithium-air batteries are even more exaggerated.

Since the official withdrawal of lithium-air batteries in October last year, the world's crude oil prices have been falling all the way. From the highest point of more than 70 US dollars a barrel, it has fallen to the current 15 US dollars a barrel.

There was even a joke that the price of crude oil futures was negative.

Domestic shale oil producers in the United States went bankrupt one after another due to long-term low crude oil prices.

Those resource countries that rely on crude oil exports for economic blood transfusion are also in trouble.

As for the petrodollar circulation established under the Bretton Woods system, it has encountered unprecedented challenges and crises.

In contrast, the RMB, backed by lithium-air batteries, has begun to rise strongly, competing with the US dollar for the status of a global trade currency.

It can be said that Pang Xuelin single-handedly changed the global political and economic structure and reshaped China's position in the world.

Because of this, Xu Xincheng and Liu Tingbo felt so incredible when Pang Xuelin said that this achievement can be compared to lithium-air batteries, or even more important.

Pang Xuelin smiled and didn't say much to them.

The research on superconducting materials is still in a highly confidential state. Even if it is successful, it needs to be discussed with high-level officials when it will be released.

Pang Xuelin is very clear that superconducting materials may not be able to have such a major impact on the global political and economic structure in a short period of time like lithium-air batteries.

However, the many potential applications of superconducting materials are enough to raise the entire industrial level of mankind to a higher level.

Among other things, superconductors play an irreplaceable role in the fields of strong electricity, weak electricity, and diamagnetism.

In the field of strong electricity, superconducting technology can make generators and motors miniaturized, with more powerful power and more stable working performance, so as to replace the current large and heavy power generation facilities, and also provide the possibility of low noise and military use of motors.

Although there is superconducting motor technology at present, a rotary infusion sealing device is required to keep the superconductor at the temperature of liquid helium.

Its performance directly affects whether the superconducting synchronous generator can run safely and reliably.

In order to ensure the cryogenic state of the excitation coil, the liquid helium cryogenic device must have the properties of insulation, heat insulation, vacuum sealing and high strength.

In addition, there are still problems such as winding manufacturing process, coil detection and protection, and reliability. Therefore, the development of superconducting motors has been subject to various restrictions.

The emergence of this room temperature superconductor is enough to make superconducting motors an ideal power for steel rolling, wind turbines, micromechanical systems, chemicals, aerospace, navigation, mining, oil and gas refining, and other heavy industries.

In addition, superconducting power technology will be widely used in superconducting cables, superconducting transformers, superconducting energy storage, superconducting motors and other fields.

In the field of weak electricity, high-speed computers require dense arrangement of components and connection lines on integrated circuit chips, but densely arranged circuits will generate a lot of heat during operation, and heat dissipation is a problem faced by VLSI. And using this superconducting material to manufacture superconducting computers, its performance is even higher than that of carbon-based chips.

The diamagnetic application of superconductivity includes superconducting maglev transportation system, superconducting maglev train and so on.

Using the diamagnetism of the superconducting material, the superconducting material is placed above a permanent magnet. Since the magnetic force lines of the magnet cannot pass through the superconductor, a repulsive force will be generated between the magnet and the superconductor, so that the superconductor is suspended above the magnet.

The emergence of room temperature superconductors will greatly reduce the cost of superconducting maglev, and even establish a nationwide superconducting maglev railway transportation system.
