Qin Anguo's actions were fast, and after giving an answer from the Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, he rushed from the capital to Jinling the next day.

Early in the morning, in the Chuanhai Materials Research Institute, Xu Chuan, who was rushing to do experimental research to optimize high-temperature copper-carbon-silver composite superconducting materials, was arrested by Qin Anguo and his party.

"Academician Xu, it's early."

Under the building, Qin Anguo walked up with a smile and greeted him warmly.

Seeing Qin Anguo, Xu Chuan was slightly stunned for a moment, and then stepped forward with a smile to greet him: "Qin Yunchang, long time no see." ”

Since Gao Hongming was arranged, this head of science and technology rarely appeared in front of him.

Qin Anguo smiled and greeted a few words, and then introduced: "Come on, come on, introduce to you." ”

"This is Zhang Pingxiang, an academician of our Chinese Academy of Sciences, who mainly studies the field of superconducting materials and has long been engaged in the research of practical low-temperature and high-temperature superconducting material preparation technology."

"Academician Zhang, this is Academician Xu Chuan, our research on high-temperature copper-carbon-silver composite superconducting materials in the past two days is the research of Academician Xu."

Xu Chuan stepped forward with a smile, shook hands with Academician Zhang, and said hello.

This Academician Zhang Pingxiang wore a pair of glasses, and his eyes looked slightly wooden or imaginary, but he was very impressed by this Academician Zhang.

If there is any researcher in the field of superconductivity in China who is well-known in the world, this academician Zhang is definitely among them.

His paper on "Basic Physical Properties of High-Temperature Superconductors Above 40K" covers a variety of systems such as copper-oxide superconductors, fullerene superconductors, iron-based superconductors and organic superconductors.

It can be said that he is one of the founders of high-temperature superconducting material systems.

His research on copper-carbon-silver superconductivity systems, as well as some of his inspiration and theories, came from Academician Zhang's 40K high-temperature superconductivity paper.

This time, Qin Anguo brought him over, obviously preparing to communicate with him to discuss high-temperature copper-carbon-silver composite superconducting materials, so he didn't stay long, and brought people to his office.

After boiling the kettle, Xu Chuan just wanted to make two cups of tea, and on the other side, Qin Anguo patted his head in annoyance, stood up with a smile, took out two well-packaged tea leaves from the backpack behind him, and stuffed them into Xu Chuan's hands.

"Academician Xu, this is the tea that I asked me to help bring to you."

Because of the relationship between Academician Zhang, Qin Anguo didn't say who brought it, but he and Xu Chuan both knew very well who sent the tea.

Pinching two boxes of well-packaged tea, Xu Chuan couldn't laugh or cry.

The old man said a few days ago that he would have someone bring him two bags of tea, and now he will send them over.

But it just so happened that it was not good to really invite this academician Zhang Pingxiang to drink a bag of tea with hundreds of pieces from Fan Pengyue.

After Xu Chuan made a pot of tea, the group chatted in the office.

When talking about things related to superconducting materials, Academician Zhang, who originally looked a little wooden, exuded a fine light in his eyes, and the whole person became a little excited.

This is the confidence that a researcher exudes when he enters his or her familiar field.

After chatting for a while and exchanging some knowledge about the field of high-temperature superconducting materials, Xu Chuan said with a smile: "The research on superconducting materials is actually a field of 'experimental leading theory'. ”

"Many times we can only find superconducting materials through various elements mixed together like 'alchemy', and then we can figure out the mechanism through the materials, Academician Zhang's 40K theory, not only in China, but also in the world, you have pointed out a path for the development of high-temperature superconducting materials."

Zhang Pingxiang shook his head and said: "This is not perfect, just some basic conceptual things, if I can, I would like to find a way to the mechanism of high-temperature superconductivity and room-temperature superconductivity." ”

Xu Chuan smiled and said, "That's just right, a few days ago I sorted out some mechanism theories about copper-carbon-silver composite materials, do you want to take a look at it?" ”

Hearing this, Zhang Pingxiang was stunned for a moment, he didn't expect Xu Chuan to make this suggestion.

To be honest, for him, the mechanism theory of high-temperature copper-carbon-silver composite superconducting materials is very tempting to him. But this core theory, he never thought about. Because this is the essence of the material, and it is also the most important thing to write a paper in the future.

After hesitating for a moment, he spoke: "Academician Xu is willing to communicate this with me?" ”

Xu Chuan smiled and said, "I studied copper-carbon-silver composite superconducting materials, and I was inspired by Academician Zhang's 40K theory, what is this?" I can't support superconducting materials alone, and with old-timers like you, this road can go further. ”

For him, the mechanism theory of copper-carbon-silver composites is not really a very important thing. Qin Anguo came over today, and the paper probably won't be sent.

Instead of holding it in your hand, it's better to communicate with someone.

Of course, the key is that the object of communication is this academician Zhang Pingxiang, if it is someone else, he probably does not come up with this theory.

On the one hand, when he was researching superconducting materials in his previous life, this academician Zhang gave him a lot of help. On the other hand, as he said, he can't pick up the overall situation of the superconducting materials industry alone, and he still needs the help of others.

In the office, Xu Chuan and Zhang Pingxiang chatted for a long time, and the two ended the exchange unsatisfied.

On the side, Qin Anguo also took the opportunity to intervene, and he asked: "Academician Xu, do you have any ideas on how to deal with high-temperature copper-carbon-silver composite superconducting materials?" ”

Xu Chuan didn't answer, but instead asked, "Does Chief Qin have any good suggestions?" ”

Since this Qin Qian is here today, then these things must have been considered above.

Qin Anguo coughed, cleared his throat, and said, "That's right, regarding the high-temperature copper-carbon-silver composite superconducting materials you developed before, the state absolutely supports all your legitimate rights and interests." However, due to the importance and particularity of this material, we hope that you will consider the matter of publishing papers and applying for patents more carefully. ”

After all, both of these aspects are enough to point out some directions and research paths for other countries. And it is not easy for us to have a material that is in front of us now, after all, our foundation is still much shallow compared to those countries, and if we can maintain our advantages, it will naturally be better. ”

"Therefore, in contrast, it is a better choice to build a factory to produce it confidentially, or to cooperate with qualified domestic enterprises to produce this high-temperature copper-carbon-silver composite superconducting material, and then sell it to the outside world. Although the recovery of funds will be slightly slower in this way, it can ensure our advantages in the field of high-temperature superconducting materials. ”

"If Academician Xu is in urgent need of scientific research funds to do research, the state can provide an interest-free loan to the Chuanhai Institute of Materials, what do you think?"

For the young scholar in front of him, at the national level, I have to consider his thoughts and opinions.

If he had to publish his papers and apply for patents, there was honestly nothing he could do. After all, they couldn't risk going wrong and forcibly stop it.

Because compared with a patent for high-temperature superconducting materials, he is a more valuable asset.

Hearing this, Xu Chuan smiled and said, "When I brought up this matter a few days ago, I thought about this aspect. The use of this material is indeed a bit sensitive, so it is indeed more appropriate to produce it yourself and then sell it. ”

"As for the production method of building a factory by itself, I am afraid it will be too late for the time being. Because one of the purposes of this material research is to replace ultra-low temperature superconducting materials to provide a strong magnetic field for controlled nuclear fusion reactors, and according to the current progress of controlled nuclear fusion engineering, it will need to be used by this time next year at the latest. ”

Hearing this, Qin Anguo also had a reassuring smile on his face: "If that's the case, I can go and collect a list of some qualified manufacturers for you, and you can pick and choose when the time comes." I'm going to get people pushing to put the production of materials on the agenda as soon as possible. ”

Xu Chuan nodded and said with a smile: "Yes, these are trivial matters, and I can find someone to deal with them instead of me when the time comes." ”

Qin Anguo said with a smile: "No problem, don't worry about this, the country will never let you suffer." ”

After a pause, he continued: "In addition, there is one more thing I want to ask you about this time. ”

Xu Chuan: "What's the matter?" ”

Qin Anguo sorted out his language for a while, and said: "It is also about the high-temperature superconducting material you have researched, about this material, we would like to ask, is there a way for you to change its physical properties, reduce its brittleness, and improve some properties in terms of toughness and strength, which can be used to make superconducting coils?" ”

Hearing this, Xu Chuan immediately understood what he wanted to do.

It's just that in this matter, he really can't help it at the moment. Even if he directly took out the normal temperature copper-carbon-silver superconducting material, he would not be able to change the physical properties of this material.

In fact, this is what he has been doing recently, and the shortcomings of high-temperature copper-carbon-silver superconducting materials such as high brittleness, low shock resistance and impact resistance, and fragility have largely limited its use.

For example, in power generation and substation equipment, even if superconductivity can be achieved by freezing liquid nitrogen to a critical Tc temperature, the vibration and interference caused by the operation of these equipment itself or the outside world can easily lead to the damage of the core superconducting materials inside.

Even if there is cushioning material to protect it outside, it cannot withstand the harsh environment of the working place of these equipment.

But if you can change its physical properties a little and make it less brittle, even if you reduce some superconducting parameters such as critical temperature, critical magnetic field, and critical current density, it is worth it.

Shaking his head, Xu Chuan said: "I'm afraid I won't be able to do it for the time being, this is actually the direction I have been studying, but there is not much progress yet." ”

On the side, Zhang Pingxiang suddenly spoke: "Academician Xu, can I join your team?" I would like to participate in the research on improving the physical properties of high-temperature copper-carbon-silver composite superconducting materials. ”

"Don't worry, I won't get involved in any papers or profit distribution issues, just treat me as an ordinary researcher in your research institute."

Hearing this, Xu Chuan glanced at Academician Zhang with some surprise, he didn't expect him to propose this, after thinking about it, he said with a smile: "If Academician Zhang doesn't dislike my small place, I am always welcome." ”
