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

"Hey, Lao Cao, what's wrong?"

"Professor Pang, it's successful!"

“Successful?!”

Pang Xuelin was slightly stunned and his voice suddenly became louder.

Since the last time he successfully constructed 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 worked with Li Changqing's team to prepare multi-walled carbon nanotube materials that meet the conditions for high-temperature superconductivity based on Pang Xuelin's theory.

But this is not an easy task.

Although Pang Xuelin and Li Changqing's team previously worked together to use computer-controlled reaction black boxes to prepare the legendary flying blade material and realize industrial production.

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

In the field of multi-wall carbon nanotubes, it is even more difficult to prepare high-purity ultra-long multi-wall carbon nanotubes.

After all, single-walled carbon nanotubes are just single-layer carbon tubes. At best, they can control the diameter of the tube at most. However, multi-walled carbon nanotubes are composed of multi-layer carbon nanotubes. In addition to considering the diameter of the tube, they also need to consider the distance, structure, chirality and other factors between different carbon layers.

As for preparing the multi-walled carbon nanotubes calculated by Pang Xuelin's theory, there are more factors to consider.

Pang Xuelin even made preparations for three to five years. He never expected that in just a few months, Cao Yuan's team and Li Changqing's team completed the preparation of this room temperature superconducting material.

No matter from which perspective, this is an extremely amazing achievement.

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

Pang Xuelin pondered for a moment and said, "I am in Jiangda now. I will wait for the laboratory, and I will talk about the others when I arrive."

"good!"

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

Xu Xincheng said curiously: "Professor Pang, what's wrong? Is there any new achievements made in Qiantang Laboratory?"

Pang Xuelin nodded with a smile and said, "It's a result! But this matter is quite serious. I have to go over and confirm it now. If there is no problem, this result should not be much worse than lithium air batteries, and it is even more meaningful!"

"Not much worse than lithium air batteries?!"

“It’s even more meaningful?!”

Xu Xincheng and Liu Tingbo looked at each other, unable to believe it.

You should know that since the launch of lithium air batteries last year, they have begun to be used in mobile phones, tablets, notebooks, cars, drones, submarines, and even new generation passenger aircraft, transport aircraft.

The political effect triggered by this product directly broke the United States' dream of curbing China's development through a trade war, and even made Western countries' technological blockade of China become a piece of waste paper.

The economic effect generated by lithium air batteries is even more exaggerated.

Since officially withdrawing from lithium air batteries in October last year, the world's crude oil price has been falling all the way. It has dropped from the highest point of more than 70 US dollars per barrel to the current $15 per barrel.

There was even a joke that crude oil futures prices were negative.

Shale oil manufacturers in the United States have gone bankrupt one after another because crude oil prices have been hovering at low levels for a long time.

Resource countries that rely on crude oil exports for economic blood transfusions are also in trouble.

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

On the contrary, rmb began to rise strongly with the support of lithium-air batteries, competing with the US dollar for the position of global trade currencies.

It can be said that Pang Xuelin changed the global political and economic landscape with his own strength and reshaped China's position in the world.

It is precisely because of this that Pang Xuelin said that this achievement can be comparable to lithium air batteries, and even more importantly, Xu Xincheng and Liu Tingbo felt so incredible.

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 will require discussion with senior management when it is released.

Pang Xuelin knew very well that superconducting materials may not be able to think of lithium air batteries in a short period of time, which will have such a significant impact on the global political and economic structure.

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

Not to mention, superconductors have irreplaceable effects in areas such as strong electricity, weak electricity, and antimagnetics.

In the field of strong power, superconducting technology can make generators and motors smaller, with more powerful power and more stable working performance, replacing the current huge and bulky power generation facilities and also providing possibilities for the low noise and military use of motors.

Although superconducting motor technology is available, it is necessary to rotate the infusion sealing device to keep the superconductor in liquid helium temperature.

The advantages and disadvantages of its performance directly affect whether the superconducting synchronous generator can operate safely and reliably.

In order to ensure the deep-cooling state of the excitation coil, the liquid helium deep-cooling device must have insulation, heat insulation, vacuum sealing and higher strength properties.

In addition, there are also problems such as winding manufacturing processes, 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 driving force for steel rolling, fan, micromechanical systems, chemical industry, 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 current, high-speed computers require densely arranged components and connecting lines on integrated circuit chips, but densely arranged circuits will experience a lot of heat when working, and heat dissipation is a problem faced by ultra-large-scale integrated circuits. However, the performance of superconducting computers using this superconducting material is even above carbon-based chips.

The antimagnetic applications of superconducting include superconducting magnetic levitation conveying systems, superconducting magnetic levitation trains, etc.

Using the antimagnetic properties of superconducting materials, the superconducting material is placed above a permanent magnet. Since the magnetic force line of the magnet cannot pass through the superconductor, a repulsive force will be generated between the magnet and the superconductor, causing the superconductor to levitate above the magnet.

The emergence of room temperature superconductors will greatly reduce the cost of superconducting magnetic levitation, and it is even possible to establish a superconducting magnetic levitation railway transportation system nationwide.
