Pang Xuelin shook his head with a smile and said, "Based on this theory alone, I don't know how long I have to wait to win the Nobel Prize." ”

The Nobel Prize is not a cabbage, the reason why Pang Xuelin was able to win the Nobel Prize in Chemistry last year was because he was nominated for his achievements in the field of carbon nanotubes and graphene.

Then, by chance, the lithium-air battery can be quickly entered into industrial production, and then the global industrial pattern will be changed, so that it can win the Nobel Prize in the year of the achievement.

Although the current superconductivity theory mechanism has taken a big step forward in the research of superconductors, if you want to win the Nobel Prize, you must verify this set of theories and obtain significant results on this basis.

In this way, it is normal to delay winning the Nobel Prize for more than ten or twenty years.

"Professor Pang, is there a way to deduce the conditions required for room-temperature superconducting materials through these formulas?"

At this time, Zhou Tong spoke up.

Everyone focused their attention on Pang Xuelin.

Zhou Tong asked the crux of the question.

Whether any new theory is correct or not must be judged by whether it can predict the existence of certain objective facts.

For example, during the discovery of Neptune, astronomers used the perturbation of Uranus's orbit to speculate on the existence and possible location of Neptune, and then verified the correctness of the law of gravitation.

For example, when Einstein proposed the general theory of relativity, it caused great controversy in the physics community until 1919, at the end of World War I, two expeditions led by British scientist Eddington took advantage of the opportunity of a total transatlantic solar eclipse to observe the distortion of light caused by gravity.

Thus the correctness of the general theory of relativity is verified.

The key to the success of this new superconductivity theory proposed by Pang Xuelin is whether it can predict the existence of some new superconductors.

Pang Xuelin pondered for a moment and said, "Yes, yes." However, it is still very difficult to use this formula to find a new superconducting material with certain properties. ”

"How?"

Zhou Tong said curiously.

Pang Xuelin said: "For example, if we substitute the superconducting transition temperature, we can deduce the superconducting condensation energy of a certain superconducting material, the energy difference with the normal state, and its magnetoresistive oscillation ratio. These properties can only indirectly help us screen for possible superconducting materials, but they cannot help us directly determine which materials they are. ”

"So how should we find a superconductor at room temperature?"

Zhou Tong frowned.

Others also looked at Pang Xuelin suspiciously, after all, Pang Xuelin's real goal was to find a superconductor at room temperature.

If we rely on this theory alone, we can only say that mankind has made a big step forward in the long journey of finding superconductors at room temperature, and no one can say when we will be able to find superconductors at room temperature in the true sense.

Pang Xuelin was not as sad as others, and said with a faint smile: "I already have a clue about finding a room temperature superconductor, and here, I want to thank Professor Cao." ”

"Thank me?"

Cao Yuan looked at Pang Xuelin in surprise, a little puzzled.

Pang Xuelin said with a smile: "Professor Cao, it was the graphene superconductivity phenomenon you discovered that provided me with clues. ”

Cao Yuan frowned and said: "Although the superconductivity phenomenon of graphene is a breakthrough, the superconducting transition temperature of graphene superconductors is below the temperature of liquid helium after all, and it has no practical value at all. ”

Pang Xuelin laughed and said: "During this time, in the process of establishing the theory of superconductivity, I have also been thinking about some candidate room-temperature superconducting materials that may exist in the future. In fact, I finished working on the entire superconductivity theory last night. Then I spent a night calculating several possible materials, and found that none of them. Finally, I suddenly thought of Professor Cao's graphene superconductivity experiment. Graphene has two superconducting states, one that applies an electric field at an angle of 1.7 degrees and exhibits superconducting properties at a transition temperature of 4.7 K. The other is to apply microwave irradiation at an angle of 2.5 degrees, and at a transition temperature of about 5 K, it exhibits superconducting properties. So I thought, graphene is a two-dimensional material, what if we roll up this graphene? What will happen? ”

"Circle the graphene......"

Dong Chenglin muttered to himself, and suddenly he had a flash of inspiration, looked at Pang Xuelin incredulously and said, "Professor Pang, what do you mean...... Carbon nanotubes? ”

Pang Xuelin nodded with a smile and said, "To be precise, it is multi-walled carbon nanotubes." So, I quickly substituted the relevant parameters into it, and the calculation results showed that theoretically, a multi-walled carbon nanotube in a special state can appear superconducting at room temperature. This state does not mean that the external application of some special conditions to the multi-walled carbon nanotubes, such as the application of electric fields or microwave irradiation. Rather, it refers to the special configuration of multi-walled carbon nanotubes. As we all know, carbon nanotubes are made from graphene material. Carbon nanotubes coiled up from a single layer of graphene material are called single-walled carbon nanotubes, while carbon nanotubes made of multi-layer graphene materials are multi-walled carbon nanotubes.

"There are many types of multi-walled carbon nanotubes, and multi-walled carbon nanotubes with different layers, different diameters, and different chiralities will show completely different properties. I have used this formula to calculate the configuration conditions of the multi-walled carbon nanotubes that we need......"

The conference room was so quiet that everyone looked at Pang Xuelin in amazement.

No one expected that Pang Xuelin would really theoretically find a possible room-temperature superconductor.

"Is this the true strength of Pang Shen?"

Tan Song, who was standing behind, whispered to Wei Wenxuan beside him.

Although Pang Xuelin said that this is due to the graphene superconductivity phenomenon discovered by Cao Yuan before, everyone understands how difficult it is to associate graphene superconductivity with multi-walled carbon nanotubes and calculate the relevant configurations through his own theory.

When Pang Xuelin and Cao Yuan collaborated to find room-temperature superconducting materials, almost everyone thought that the research would not succeed in a short period of time.

After all, scientists have not even come to a unified conclusion on how superconductivity is generated, and it is almost impossible to find a room-temperature superconductor that can be used in the real sense.

No one expected that Pang Xuelin would really succeed.

Even if it has not been experimentally verified, Pang Xuelin was able to put forward this theory and give a clear material option, which is enough to show how awesome he is.

While Tan Song and Wei Wenxuan sighed, Cao Yuan also had a ghostly expression.

In his heart, Pang Xuelin is already powerful enough, after all, he was able to unify the superconductivity theories of various schools in such a short period of time and establish a complete mathematical model.

Relying on this achievement alone, after more than ten or twenty years, a Nobel Prize in physics will be firmly on Pang Xuelin's head.

But he didn't expect it. Pang Xuelin actually gave specific material options.

And from Pang Xuelin's tone, it is obvious that he is quite sure of multi-walled carbon nanotubes.

As for Zhou Tong and Dong Chenglin.

Zhou Tong is completely a little fan girl's expression, and he doesn't seem surprised that Pang Xuelin has such ability.

Dong Chenglin gave a thumbs up and said with a smile: "Pang Shen, you are awesome, I finally understand now why your Qiantang laboratory is so popular." If it weren't for the fact that I had just signed a five-year contract with HKUST, I would have the urge to switch to your front office. ”

Pang Xuelin laughed and said, "If you want to work in the Qiantang Laboratory, you don't need to switch, you can clean up, and you can go to Jiangcheng tomorrow." ”

"What are you doing in Jiangcheng?"

Zhou Tong looked at Pang Xuelin with some blankness.

Cao Yuan, who was on the side, explained with a smile: "Don't forget, Professor Pang's carbon nanomaterials research center is the world's top carbon nanotube research institution, and if we want to find the superconducting carbon nanotubes that Professor Pang said, we have to go to Jiangcheng to cooperate with them." ”

Only then did everyone suddenly realize.

Pang Xuelin said with a smile: "What Professor Cao said is right, let's go back and prepare, tomorrow I will arrange someone to take you to Jiangcheng, if you drive to Yexing by yourself, anyway, Luzhou is not far from Jiangcheng, and the highway is only a few hours, and the Qiantang Laboratory will arrange a place for you to live." ”

"Okay, then we'll go and get ready."

Dong Chenglin thought about it, took out his mobile phone, stepped forward to take a picture of Pang Xuelin's board book, and then said to Wei Wenxuan and Tan Song: "You two take off this whiteboard and replace it with a new one." ”

"Lao Dong, what are you doing here?"

Pang Xuelin was a little curious.

Dong Chenglin smiled: "Of course, I took it for collection." You don't know, the ABC conjecture you made in Paris proves that it has now become a well-known attraction of that hotel, and even half of those board books have been detained by the Paris Masters and become the collection of their library, and the other half have been collected by the Chinese Mathematical Society. This time too, if your theory is tested, I am afraid that this tabula rasa will also become a cultural relic in the future. ”

Hearing him say this, Zhou Tong, Wei Wenxuan, and Tan Song also stepped forward one after another and took a picture of Pang Xuelin's board book with their mobile phones.

Pang Xuelin couldn't cry or laugh, so he could only let them toss.

After deciding on the plan to return to Jiangcheng, Pang Xuelin and Cao Yuan went to the president's office to say goodbye to Lu Dongming, president of HKUST.

Subsequently, Pang Xuelin returned to the expert building, and Zuo Yiqiu and Zhou Chen had already packed his luggage.

In the afternoon of the same day, Pang Xuelin returned to Jiangcheng.

The car drove into the garage of the villa, Pang Xuelin got out of the car and came to the door, and the door was hidden, he pushed the door directly, only to hear a poof, and the confetti in the sky was scattered one after another.

Immediately afterwards, the lights in the living room, which had been somewhat dim because the curtains were closed, suddenly turned on.

"Happy birthday to you, happy birthday to you......"

In the birthday song, Qi Xin, Yao Bingxia, parents, and grandparents all walked out of the corner.

Pang Xuelin suddenly felt that his eyes were a little moist.

He rarely celebrates his birthday, especially after getting the system, and entering a world can be as short as a few years, often tens or hundreds of years.

Pang Xuelin himself almost forgot what day his birthday was.

Especially in the past two years, his work has become more and more busy, and on his birthday last year, Yao Bingxia was not around, but just called Pang Xuelin to say happy birthday.

Not to mention the year before last, neither of them was together yet.

Pang Xuelin didn't expect that as soon as they went home today, they would give themselves such a big surprise.

However, Pang Xuelin quickly reacted and said, "Mom, how do you know that I am coming back today?" Also prepared a birthday cake for me in advance? ”

Immediately, Pang Xuelin turned his gaze to Zuo Yiqiu on the side.

Except for Zuo Yiqiu's leaked news, there will be no second person.

Zuo Yiqiu stuck out his tongue at him and turned his head away.

At this time, Qi Xin smiled and said, "Ah Lin, don't blame Sister Zuo, it was me and Xiao Xia who wanted to celebrate your birthday." Originally, because you were in retreat, we wanted to go to HKUST to surprise you, but I didn't expect Sister Zuo to call this morning and say that you will be back today, so we simply held a birthday party for you at home. ”

Pang Xuelin had a bright smile on his face, and said a little choked: "Thank you, thank you." ”

After the birthday cake, there will be a big dinner in the evening.

Mei Yuqing, Qi Xin, Yao Bingxia and Zuo Yiqiu all went to the kitchen to help Aunt Zhou.

Pang Xuelin accompanied his father and grandfather Peng Shao'an and chatted in the study.

The three of them unconsciously talked about the problem of Jinlong battery.

"Dad, how is the Golden Dragon battery now?"

Pang Yongnian said: "We have almost talked with Europe, Southeast Asia, the Middle East, and Russia, and the United States is still arguing. Now there are two cooperation models, first, Southeast Asia and the Middle East are mainly based on the establishment of wholly-owned production lines by our Golden Dragon Group. The second is the joint venture between Russia and Europe. Not to mention the profit from selling products, the annual patent fee alone is more than 10 billion US dollars. As for the U.S. side, the United States is asking for patent licensing and U.S. sole proprietorship, while our side is asking for a joint venture between the two sides, and they are still arguing with each other. However, I estimate that the United States will not last long, and the European side has lifted the restrictions on the Warwasena agreement, and there is no point in the United States blocking it any longer. And now that there are so many protests in the United States, I think we should be able to reach an agreement within a month or two. ”

Pang Yongnian paused and continued: "In addition, Tesla's Chinese factory has obtained a license, but their King Long battery cars can only be sold in our country and are not allowed to be exported. Hongqi, Geely, NIO and other car companies have also signed relevant cooperation agreements. Now that global car companies are undergoing a major transformation, gasoline vehicles at home and abroad cannot be sold at all. Now that the price of international crude oil futures has fallen to $20 a barrel, it is estimated that there is still a lot of room for decline in the future. Moreover, COMAC has also begun to reach an agreement with Jinlong Group on cooperation in the development of electric passenger aircraft, and our Xinkai company is the designated composite material supplier of COMAC, which should have a great future in the future. Hehe, Kobayashi, the position of this composite supplier is all about what I talked about......"

At this time, Pang Shaoan said: "Don't talk about your business experience, Xiaolin, I heard that you are engaged in superconductors at the University of Science and Technology, how is the progress now?" ”

Pang Xuelin said with a smile: "It's okay, I'm a little eyebrow-raising, as for what step I can do next, it's hard to say now." ”

Pang Shaoan nodded and said, "Xiaolin, remember to guard against arrogance and rashness, I heard that you are preparing to engage in an electromagnetic catapult space launch system, is this reliable?" ”

Pang Xuelin was slightly stunned, looked at Pang Shaoan with some surprise and said, "Grandpa, how do you know about this?" ”
