When Pang Xuelin arrived at the Qiantang Laboratory, it was already two o'clock in the afternoon.

"Professor Pang!"

Cao Yuan and Li Changqing were waiting at the entrance of the Carbon Nano Research Center building early in the morning.

"Professor Cao, Professor Li, you have worked hard!"

Pang Xuelin stepped forward and shook hands with Cao Yuan and Li Changqing one by one.

Cao Yuan smiled but said nothing.

Li Changqing said with a smile: "What kind of hard work is this, we just make it step by step according to the theoretical model you gave." ”

When he said this, Li Changqing still had a trace of amazement on his face.

You must know that when Pang Xuelin took Cao Yuan's team to Qiantang Laboratory and asked Li Changqing's team to cooperate with them to find room-temperature superconductors, Li Changqing was still a little hesitant.

If it weren't for his trust in Pang Xuelin, Li Changqing would not have believed that the special configuration of multi-walled carbon nanotubes could form room-temperature superconductors.

This is completely beyond his theoretical understanding.

However, the experimental results proved that Pang Xuelin's theory was correct.

After the results of today's experiment came out, Li Changqing was excited and excited.

The last time the lithium-air battery was held, Qian Xingmin, who was engaged in large-size graphene at the Carbon Nanomaterials Research Center, tasted the sweetness.

After the industrialization of lithium-air batteries, Xinkai Materials and the large-size graphene project team can be said to have made a lot of money, and any professor-level senior engineer in it is worth hundreds of millions.

However, the flying blade material project and carbon-based chip project that Li Changqing is responsible for have always been in a tepid state.

If you want to say in your heart that you don't envy, it's impossible.

Now, it's finally his turn.

Room-temperature superconductors, this is a Nobel Prize-level achievement, and it is fully qualified to run for next year's Nobel Prize in Physics!

Not to mention the subsequent benefits of this material, it is a super gold mine that can be eaten for decades.

Li Changqing is now in his fifties, and he has begun to slowly get out of the front-line scientific research state.

To be able to achieve such outstanding results in the last years of his research career is worth it.

The three of them exchanged pleasantries at the gate of the Carbon Nano Research Center for a while, and then directly entered the building of the Carbon Nano Research Center.

The entire carbon nano research center is quiet.

This project was arranged by Pang Xuelin under the electromagnetic catapult space launch system, the level of secrecy is very high, the entire building is full of code doors, and the elevator can only reach the designated floor through security.

And these security guards are actually all arranged by the national security system.

Because of this, when Pang Xuelin and the others entered the research center building, the entire research center was quiet.

No one knew that in this building, another super-achievement had been successfully carried out that could shake the whole world.

When Pang Xuelin followed Cao Yuan into the laboratory, he found that no one was busy in the laboratory, and all the researchers involved in this project stood in two columns, Zhou Tong, Dong Chenglin, Wei Wenxuan, Tan Song and others were looking at Pang Xuelin with fanatical eyes.

"What's wrong with everyone? Why are you staring at me? ”

Pang Xuelin said with a smile.

Bang Bang Bang ......

Zhou Tong, who was standing in the forefront, took the lead in applauding, and soon, the applause resounded throughout the laboratory.

Although because of the number of people, there is no feeling of thunder, but Pang Xuelin can feel that everyone's applause implies sincerity.

After a long while, the applause gradually stopped.

Zhou Tong said with a smile: "Professor Pang, without your theoretical guidance, we would not have been able to achieve today's results, thank you!" ”

Dong Chenglin also said with a hint of fanaticism on his face: "Zhou Tong is right, Professor Pang, you don't know, the experimental samples we made are as consistent with the theoretical predictions as high as 99%, which is definitely one of the most outstanding achievements in the history of science in the 21st century......

Pang Xuelin smiled and said, "Okay, you don't have to praise me, are the samples and experimental reports there?" Show me! ”

Soon, Pang Xuelin saw a sample of superconductors at room temperature.

It is a 10-centimeter-long, hair-thin, multi-walled carbon nanotube, with a black overall appearance, which looks like ordinary hair.

If it weren't specifically explained, no one would be able to see that the manufacturing cost of this short filament in front of him alone would be as high as tens of millions.

The experimental report records in detail the characteristics of this carbon tube, such as the critical temperature, critical magnetic field, critical current and critical current density, all of which fully meet the standards for large-scale application.

The experimental data are very well documented, and the report is somewhat sketchy due to time, but there are few flaws overall.

After reading the report, Pang Xuelin said to Cao Yuan and Li Changqing on the side: "Professor Cao, Professor Li, I basically read the report and did a great job, but for us, this is just a phased achievement, and our next research will focus on two directions!" ”

"Professor Pang, which two directions?"

Cao Yuan said curiously.

Pang Xuelin said: "The first direction, the magnetic flux dynamics and superconductivity mechanism of unconventional superconductors, mainly studies the mechanism of magnetic flux line motion in the mixed region, the irreversible line properties, causes and their relationship with magnetic field and temperature, and the dependence and anisotropy of critical current density on magnetic field and temperature. The study of superconductivity mechanism focuses on the magnetoresistance, Hall effect, fluctuation effect, Fermi surface properties and T under strong magnetic fields under normal conditions

In addition, it is necessary to study the new phenomena and singular properties of this material in the very micro-scale system, which is closely related to the microstructure of this material, especially the electronic structure. The strong magnetic field provides a powerful means to study the electronic state and transport characteristics of very microscale systems, which can not only further reveal the strange phenomena that are difficult to occur under conventional conditions, but also provide rich scientific information for understanding their physical properties at a deeper level. In addition to the physical properties, it is also necessary to consider the effect of the strong magnetic field on the electron spin and nuclear spin of the chemical reaction, which can lead to the relaxation of the corresponding chemical bonds, resulting in favorable conditions for the formation of new bonds. For example, an important conceptual development in the eighties was the discovery of the quantum Hall effect and the fractional quantum Hall effect. This was discovered when studying the transport phenomenon of two-dimensional electron gases under a strong magnetic field. The discovery of the quantum Hall effect and the fractional quantum Hall effect has aroused the enthusiasm of physicists to explore their origins, and has shown great significance in establishing a natural benchmark for electrical resistance, accurately determining the fundamental physical constants e,h and fine structure constants (=e2/h(0c). The final revelation of the mechanism of high-temperature superconductivity will also depend to a large extent on the exploration of the properties of high-temperature superconductors under strong magnetic fields......"

"These theoretical mechanisms need to be solved by this hair-sized superconductor at room temperature!"

Cao Yuan on the side nodded and said with a smile: "Professor Pang, I understand what you mean." ”

Pang Xuelin's idea is obviously to use this super material to improve the relevant theory of high-temperature superconductivity, expose some physical and chemical mechanisms inside this material, and explore the application direction of this material.

This is exactly what Cao Yuan wants to do next.

Pang Xuelin smiled, turned his gaze to Li Changqing and said: "Professor Changqing, your research direction, that is, how to realize the industrial production of this material, your team has accumulated rich experience in the industrialization of flying blade materials before, I hope that in this multi-walled carbon nanotube superconductor, your team can form a breakthrough as soon as possible." ”

Li Changqing nodded, and said with a straight face: "Professor Pang, don't worry, we promise to complete the task!" ”
