Great Country Academician

In July 23, researchers from the Quantum Energy Research Center (Q-centre) and Korea University in South Korea gave the superconducting community, or the world, a "unreviewed" heavyweight.

The research team announced that it had successfully synthesized the world's first room-temperature and normal-pressure superconductor.

That is, under normal pressure conditions, a modified lead-apatite (named LK-99) can behave as a superconductor below 127°C (Tc≥400k).

Once this research result was announced, it caused quite a stir around the world.

Not only because of the fame of room-temperature superconducting materials, but also because of the synthesis method of this modified lead-apatite material.

Compared with the usual superconducting materials, whether it is low-temperature superconducting, high-temperature superconducting, or room-temperature superconducting materials that require extremely harsh environmental materials, the synthesis method of this modified lead-apatite (LK-99) material is a bit too "child's play".

Although there are relatively cumbersome steps, in simple terms, its synthesis method is actually to mix several powdered compounds containing lead, oxygen, sulfur and phosphorus together, and then heat them at high temperature for several hours.

During this period, these powders containing lead, oxygen, sulfur and phosphorus will undergo chemical reactions to obtain a lead-apatite crystal doped with copper.

This is the so-called KL-99 room temperature superconducting material.

Like the method used by ancient alchemists to make elixirs, it is relatively rare in the superconducting world, let alone in other materials.

After all, with the advancement of industrialization and technology, today's material smelting is no longer as rough as it was in the last century.

Whether it is nanotechnology, 3D printing, or self-propagating high-temperature synthesis technology, etc., they have already formed their own systems.

The synthesis method of KL-99 modified lead-apatite material is really too rough.

As expected, this legendary room temperature superconducting material was directly slapped to death by the famous Professor Xu Chuan in the face of doubts from all over the world within less than a month.

A year and a half later, the KL-99 material, which had long been unknown, reappeared in the public eye because of two papers on Arxiv.

However, this time it was just a "foil". What everyone was talking about was a room-temperature superconducting material called copper oxide-based chromium-silver system and a paper titled "Room-temperature superconducting mechanism of copper oxide-based chromium-silver system materials".

Room-temperature superconducting material!

This term, which had been silent for a year and a half, once again appeared in the eyes of the academic community, the materials community, and even everyone in the world because of two papers on the arxiv preprint website.

Not only because it was about room-temperature superconducting materials, but also because of the uploader of these two papers.

Xu Chuan!

This well-known name in the academic community once again made his research results public.

The last time was the proof of the weak Riemann hypothesis, and this time, it was the room-temperature superconducting material that he had personally disproved.

At the World Materials Research Institute Forum, relevant discussion topics have been established.

"The latest news! Professor Xu Chuan, a top scholar in China, published his latest research results on the Arxiv preprint website, 'Copper oxide-based chromium-silver system·room temperature superconducting materials' and related papers on the mechanism of room temperature superconductivity!"

As soon as the relevant discussion topic was established, many scholars and netizens poured in the next second.

It's just that this discussion topic is too explosive.

[WTF? ? ? ? Room temperature superconductivity? ? ? Here it comes again? ? ? ]

[Wait, Professor Xu Chuan? Is it the Professor Xu Chuan I know? Doesn't he study mathematics and physics? When did he enter materials science? ]

[Are you African above? Professor Xu has been conducting research and development in the field of materials science. High-temperature copper-carbon-silver composite superconducting materials and artificial SEI films were developed by him. ]

[What the hell? ? Academician Xu published a paper? Or is it the result of room temperature superconducting materials? ? ]

[Yes, just an hour ago, Professor Xu Chuan officially published two papers on arxiv, one is 'Copper Oxide-Based Chromium-Silver System Room-Temperature Superconducting Materials' and related test data, and the other is a mechanistic paper on room-temperature superconductivity. ]

[I'll go now! ]

[Don't go, arxiv is down, you can't get in. If you know any mathematicians or physicists, maybe you can ask them if they have downloaded papers. Or wait for arxiv to recover. ]

[Mathematicians? Why look for mathematicians? ]

[Because most of the people who follow Professor Xu Chuan on arxiv are mathematicians or physicists, and scholars in the field of materials science generally rarely go there, so they are the first to get the news. ]

As discussed on the World Materials Research Institute forum, the first batch of people who got the data of the 'Copper Oxide-Based Chromium-Silver System Room-Temperature Superconducting Materials' paper were mostly mathematicians and physicists who followed Xu Chuan on arxiv.

After the relevant news leaked, the preprint server, which is now operated by Cornell University, was directly overwhelmed by the surge of traffic.

In the School of Computer Science at Cornell University, the sweaty server administrator restored the arxiv preprint server step by step under the watchful eyes of the school leaders, and then mounted the idle computer resources on it synchronously to cope with the huge traffic impact.

If it were news about simple room temperature superconducting materials, it would be nothing to arxiv, which has experienced development in recent years.

But the key point is that this news was released by the famous Professor Xu Chuan.

The combination of the two is not simply one plus one equals two, but one plus one equals one hundred, or even one thousand.

I am afraid that as soon as arixv is restored, everyone in the academic world will flock in.

Ensuring that preprint sites can handle such exaggerated traffic is no simple matter.

While the administrator of the School of Computer Science restored arxiv, on the other side of Cornell University, in an office in the teaching building of the School of Engineering.

The two professors of materials science who have received the news are each holding a paper and are flipping through it. Although arxiv has been suspended, it does not affect their access to the paper.

"Professor O'Connor, what do you think?"

In the office, a middle-aged man with a beard closed the paper in his hand, breathed a long sigh of relief, and looked at another thin professor sitting opposite the sofa.

Upon hearing the inquiry, Professor O'Connor Elliot said without raising his head: "Wait a moment."

He hasn't finished reading the paper in his hand. To be precise, he hasn't finished reading it for the third time.

Across the way, Professor Steele Hobert, who asked the question, didn't pay much attention, picked up the coffee at hand and drank it.

After waiting for half a cup of coffee, Professor O'Connor Elliot put down the paper in his hand and spoke with emotion.

"Awesome! I didn't expect that the mechanism of room temperature superconductivity can be explained from the perspective of electron delocalization. It is indeed Professor Xu."

Opposite the sofa, Steele Hobert smiled without any surprise and said: "Explain the regular placement in the crystal lattice of the space group (SG) in superconducting materials through the grand unified framework theory of strongly correlated electron systems. , this idea is truly unique.”

"What I care more about is the copper oxide-based chromium-silver system room temperature superconducting material. You know, if this is true, the whole world will change!"

O'Connor Elliot took a sip of his coffee, thought for a while and said, "It is indeed difficult to imagine room-temperature superconducting materials at three standard atmospheres."

If other scholars or research institutions disclose room temperature superconducting materials, the first reaction of most research institutions or scholars may be to question it.

Questioning the authenticity and whether it is really superconducting

After all, the concept of room temperature superconductivity has been studied for a century. There have been many news releases, but none of them are true.

But the news released by Professor Xu Chuan, I am afraid that the first reaction of most people will be surprise and shock.

Including him and Steele, the first reaction was shock, surprise, and it was hard to imagine how that person did it.

There will still be doubts, but not now.

At least, in their first reaction, they almost instinctively believed that the other party really did it.

Everyone in the academic world knows how rigorous and serious that person is about academic research. It can be said that almost every paper and every result he released was made public only after repeated demonstrations.

Especially in the field of superconducting materials, he developed the high-temperature copper-carbon-silver composite superconducting material with the best comprehensive performance in the world.

Although the temperature of 152K is still a long way from room temperature, it does not seem to be that surprising that he developed room temperature superconducting materials on this basis.

Just like in the mathematics community, almost everyone believes that Professor Xu Chuan, who solved the weak Riemann Hypothesis, is the most likely to solve the Riemann Hypothesis.

Opposite the sofa, Steele Hobert smiled and said, "The superconducting world is about to change."

Putting down the coffee cup in his hand, Professor O'Connor Elliott shook his head gently and added: "Not only the superconducting world, but also the material world, or the entire world is about to usher in a new round of changes. "

After a slight pause, his eyes fell on the paper on the coffee table, and then said: "The concept of applying electron delocalization to inorganic materials and metallic materials is amazing. This will be a major branch of the materials world, and also He has created another discipline that will be the key direction of future materials research.”

"pity."

Speaking of this, Professor O'Connor Elliot sighed.

Unfortunately, the paper "Room Temperature Superconducting Mechanism of Copper Oxide-Based Chromium-Silver Materials" only describes the mechanism, but does not explain in detail how to apply the electron delocalization effect to inorganic materials and on metal materials.

Although this is not the most important thing in "The Mechanism of Room Temperature Superconductivity of Copper Oxide-Based Chromium-Silver Materials", it is what he wants to see the most.

He was certain that that person had a complete method in his hands.

It is even possible that the copper oxide-based chromium-silver room temperature superconducting material was developed based on that method.

If it were anyone else, O'Connor Elliott would not have made such speculations.

Because for the materials science community, the various properties of materials are generally studied only after materials have been developed.

Although it is not impossible to develop a new material based on theoretical mechanisms, it is extremely rare to do so.

Especially for materials like room temperature superconductivity, which involve various complex theories, it is even more impossible.

But when it comes to that person, it's not impossible.

Since becoming famous, what he is best at is the construction of various theories.

Whether it is the mechanism of high-temperature superconducting materials or the unified framework theory of strongly correlated electrons, the theory is first constructed and then studied or verified in comparison.

If it is in the mathematical world, this is not a rare thing.

Mathematicians are best at this.

But in the physics world, it is difficult.

After all, physics is a discipline that observes nature, discovers and studies the most general laws of motion and basic structures of matter.

Of course, O'Connor Elliott is also very clear that the method of designing the detailed basic structure of the electron delocalization effect, let alone Xu Chuan, even he himself cannot make it public.

Especially this kind of development involving room-temperature superconducting materials and future materials science, it is no exaggeration to say that this is something that can shake the foundation of the country and affect the world pattern.

On the other side, the Eurasian continent across the sea.

China, Beijing, Institute of Physics, Huazhong University of Science and Technology, State Key Laboratory of Superconductivity.

Sitting in his office, sitting in his office, dealing with the work at hand, Director Zhou Xingjiang is wearing a pair of glasses and flipping through the documents in his hands.

As the director of the State Key Laboratory of Superconductivity, his daily work is mainly in the research and development and application of superconducting materials.

Whether it is the exploration and research of new superconducting materials, the mechanism and related physical research of superconducting materials, or the preparation of superconducting films and the application research of superconducting film devices, etc., they are all the work of the laboratory.

In front of him was a research report on the application of high-temperature copper-carbon-silver composite superconducting material devices.

Although this is the research result of the Chuanhai Materials Research Institute, the Western Superconducting Group has the extended application rights of the materials after signing the production contract.

This report was submitted by the Western Superconducting Group.

After several years of production research, the Western Superconducting Group has successfully manufactured some "electronic devices" using high-temperature copper-carbon-silver composite superconducting materials in the laboratory.

The report in his hand was submitted by the Western Superconducting Group, hoping to further expand the application of "superconducting electronic devices".

For the development of superconducting materials and the country, this is a good thing. Zhou Xingjiang did not hesitate too much. After thinking about some details, he was ready to sign and approve the report.

At this time, the open door was knocked twice, and an assistant walked in quickly.

"Director Zhou, the latest news is that under the leadership of Academician Xu Chuan, the Sichuan Institute of Materials has produced room-temperature superconducting materials!"

"What?" Hearing this, Zhou Xingjiang looked at his assistant in astonishment as he was about to sign with his pen in the air: "Are you sure?"

The assistant nodded quickly and said: "Academician Xu Chuan has already made this news public and sent us a copy of room-temperature superconducting materials by post."

Hearing this, Zhou Xingjiang stood up suddenly, pushed his chair away and walked out.

"Where are the materials? Take me to see!"
