Great Country Academician

Qin Anguo acted very quickly. After the Institute of Materials Technology and Engineering of the Chinese Academy of Sciences gave a reply, he rushed from the capital to Jinling the next day.

In the early morning, in the Chuanhai Institute of Materials, Xu Chuan, who was rushing to conduct experiments to optimize high-temperature copper-carbon-silver composite superconducting materials, was caught by Qin Anguo and his team.

"Academician Xu, good morning."

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

Seeing Qin Anguo, Xu Chuan was stunned for a moment, then stepped forward to greet him with a smile: "Long time no see, Mr. Qin."

Since Gao Hongming was arranged to come here, the head of the science and technology department seldom appeared in front of him.

Qin Anguo exchanged a few words of greeting with a smile, and then introduced: "Come, come, let me introduce you."

"This is Academician Zhang Pingxiang from the Chinese Academy of Sciences. He mainly studies the field of superconducting materials and has long been engaged in the research of practical low-temperature and high-temperature superconducting materials preparation technology."

"Academician Zhang, this is Academician Xu Chuanxu. It is Academician Xu who researched the high-temperature copper-carbon-silver composite superconducting material we have been studying in the past two days."

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

This academician Zhang Pingxiang wears a pair of glasses, his eyes look a little dull or wandering in the sky, but he has a deep impression of this academician Zhang.

If there is any domestic researcher in the field of superconductivity who is well-known in the world, this Academician Zhang is definitely one of them.

His paper on "Basic Physical Properties of High-Temperature Superconductors Above 40K" covers cuprate superconductors, fullerene superconductors, iron-based superconductors and organic superconductors.

It can be said to be one of the founders of the high-temperature superconducting material system.

His research on the copper-carbon-silver superconducting system, as well as part of his inspiration and theory, came from the 40K high-temperature superconducting paper of Academician Zhang.

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

After boiling a pot of water, Xu Chuan just wanted to make two cups of tea. On the opposite side, Qin Anguo patted his head in frustration, 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 asked me to bring you."

Because of the presence of Academician Zhang, Qin Anguo did not say who brought the tea, but both he and Xu Chuan knew who brought the tea.

Holding two boxes of well-packaged tea leaves, Xu Chuan was a little dumbfounded.

A few days ago, the old man said that he would have two packs of tea brought to him, and they are here now.

But it just so happened that it would not be too good to invite this academician Zhang Pingxiang to drink the hundred yuan a bag of tea that he passed over from Fan Pengyue.

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

After talking about things related to superconducting materials, Academician Zhang, who looked a bit dull at first, had a bright look in his eyes, and his whole person became a little excited.

This is the confidence exuded by a scientific researcher after entering a field he is familiar with.

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

"In many cases, we can only find superconducting materials by mixing various elements together like 'alchemy', and then use the materials to figure out the mechanism. Academician Zhang's 40K theory is not only famous in China, but also in the world. Your theory, you have pointed out a way for the development of high-temperature superconducting materials."

Zhang Pingxiang shook his head and said, "It's not perfect, it's just some basic conceptual stuff. If possible, 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. Would Academician Zhang take a look?"

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

To be honest, for him, the mechanism theory of high-temperature copper-carbon-silver composite superconducting materials is very attractive to him. But this core theory, he never thought about it. Because this is the foundation of the material, and it is also the most important thing for subsequent writing papers.

After hesitating for a moment, he said, "Academician Xu is willing to share this with me?"

Xu Chuan smiled and said, "I was inspired by Academician Zhang's 40K theory when I studied copper-carbon-silver composite superconducting materials. What's the matter? I can't support superconducting materials by myself. Without you With such seniors, this road can go further.”

For him, the mechanism theory of copper-carbon-silver composite materials is not really important. Qin Anguo came over today, and the paper probably won't be published.

Instead of pinching it in your hand, it is better to communicate with others.

Of course, the key point is that the person to communicate with is Academician Zhang Pingxiang. If it is someone else, he probably came up with this theory.

On the one hand, this Academician Zhang gave him a lot of help when he was researching superconducting materials in his previous life. On the other hand, as he said, he alone cannot provoke the overall situation of the superconducting material industry, and still needs the help of others.

In the office, after Xu Chuan and Zhang Pingxiang chatted for a long time, the two ended their exchange with unfinished business.

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 the high-temperature copper-carbon-silver composite superconducting material?"

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

Since this Chief Qin is here today, the higher-ups must have considered these things.

Qin Anguo coughed, cleared his throat, and said, "It's like this. Regarding the high-temperature copper-carbon-silver composite superconducting material you developed before, the state absolutely supports all your legitimate rights and interests. It's only limited by the limitations of this material. Because of its importance and particularity, we hope that you will consider publishing papers and applying for patents more carefully."

"After all, these two aspects are enough to point out some directions and research paths for other countries. It is not easy for us to have a leading material now. After all, our foundation is still much shallower than those countries. , if we can maintain our advantage, it will be better."

"So in comparison, it is a better choice to keep secret to build a factory and produce it yourself, or to cooperate with a qualified domestic company to produce this high-temperature copper-carbon-silver composite superconducting material, and then sell it to the outside world. Although this way to recover funds It will be slightly slower, but it can guarantee our advantages in the field of high-temperature superconducting materials."

"Academician Xu, if you are in urgent need of scientific research funds for your research, the state can provide an interest-free loan to the Chuanhai Materials Research Institute. What do you think?"

For the young scholar in front of him, at the national level, he has to take his thoughts and opinions into consideration.

If he insists on publishing papers and applying for patents, to be honest, there is nothing the higher authorities can do. After all, it is impossible for them to take the risk of turning against each other to forcefully stop this matter.

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

Hearing this, Xu Chuan smiled and said, "When I brought up this matter a few days ago, I thought about it. 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 self-built factories, it may be too late for the time being. Because one of the purposes of this material research is to replace ultra-low temperature superconducting materials and provide strong magnetic fields for controllable nuclear fusion reactors. According to the current controllable The progress of the nuclear fusion project will need to be used by this time next year at the latest."

Hearing this, Qin Anguo put a reassuring smile on his face: "If that's the case, I can collect a list of qualified manufacturers for you, and then you can just choose it. I will let people supervise The production of materials will be put on the schedule as soon as possible.”

Xu Chuan nodded and said with a smile: "Yes, these are trivial matters, and I can find someone to handle them instead of me."

Qin Anguo smiled and said: "No problem, you can rest assured that the country will never let you suffer."

After a pause, he continued: "Besides, there is one more thing I want to ask you about this time I'm here."

Xu Chuan: "What is it?"

Qin Anguo sorted out his language, and said, "It's also about the high-temperature superconducting material you researched. Regarding this material, we would like to ask, is there any way you can change its physical properties and reduce it? Its brittleness improves some properties of toughness and strength, and can it be used to make superconducting coils?"

Hearing this, Xu Chuan immediately understood what the higher-ups wanted to do.

It's just that in this matter, he really can't do anything at the moment. Even if he directly took out the room-temperature copper-carbon-silver superconducting material, he could not change the physical properties of this material.

In fact, this is what he has been doing recently. The high-temperature copper-carbon-silver superconducting material is brittle, has low shock resistance and impact resistance, and is fragile, which largely limits its use.

For equipment such as power generation and substation, even if it is possible to achieve superconductivity through liquid nitrogen freezing to the critical Tc temperature, the vibration and interference caused by the equipment itself or the outside world can easily lead to damage to the core superconducting material inside. .

Even if there is a cushioning material for protection on the outside, it cannot withstand the harsh environment where these equipment work.

But if its physical properties can be slightly changed to make it less brittle, even if it reduces some superconducting parameters such as critical temperature, critical magnetic field, and critical current density, it is worthwhile.

Shaking his head, Xu Chuan said, "I'm afraid I can't do it for the time being. This is actually the direction I've been researching, but there hasn't been much progress yet."

On the side, Zhang Pingxiang suddenly said: "Academician Xu, can I join your team? I want 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 benefit distribution issues, just treat me as an ordinary researcher in the research institute under your name."

Hearing this, Xu Chuan glanced at Academician Zhang in surprise. He didn't expect him to bring this up. After thinking about it, he smiled and said, "If Academician Zhang doesn't dislike my small place, I welcome you at any time."
