Chapter 131 I wonder if you have won the lottery too
"Guangshen, your surprise is a bit too sudden." When I saw Lao Zhao again this time, he no longer looked as polite and meticulous as before. He had just been busy for twenty-four hours without any rest, and the exhaustion on his face could be seen without any explanation.
In just ten minutes after Chen Yuanguang posted on Weibo, Lao Zhao and his department began to operate at full speed, including contacting various places, sending people to blockade the park where Guangjia Aerospace is located, and sending people to protect Chen Yuanguang’s parents and him Connect with people you know, experts and think tanks.
China also has think tanks, but compared to Amerikan's think tanks, their influence and capabilities are much weaker.
The fundamental reason is that there is a problem with the position of the Chinese Humanities and Social Sciences Expert Station, which always wants to surprise its allies.
"I just did a small replication experiment to let you worry about it." Chen Yuanguang was very polite.
“This is our Bureau Chen, and we are the same as you. Bureau Chen will chat with you later. In addition, we brought experts from the Chinese Academy of Sciences here this time.
We hope to verify that normal temperature The authenticity of superconductivity." Lao Zhao's tone was also full of fatigue.
He has been working at high load since he received the order, and his brain has never stopped.
"Hello, Mr. Chen, I have admired your name for a long time but have never had the opportunity to meet. This meeting is a bit hasty. I am the responsible comrade of the ***** Bureau. Compared with Lao Zhao and Lao Wu, I have certain
So this time I will talk to you to avoid having to exchange a few pieces of information between us. "Bureau Chen gives people a very ordinary feeling, the kind you see passing by on the roadside but can't remember what he looks like.
Chen Yuanguang knows that this is a necessary quality, and he probably did it when he was young It was also the master who came out, "Okay, welcome everyone.
I don’t think we need to talk too much. Let’s verify room temperature superconductors first?
In addition, we have prepared papers here that you can take a look at first. "
Old Zhao and other experts looked at Director Wu, and he nodded: "Okay, let's verify the authenticity first.
This is not a distrust of you. "
Chen Yuanguang said: "Understood. "
"Guangshen, I have heard of you before. Principal Dou always shows off how powerful their students are in front of me. I have heard of you since you posted your first Nature article. .
This time I am honored to test the normal temperature superconductor. I mainly look at the resistance performance and its Meissner effect. "This time the person here is Academician Chen Xianhui. His main scientific research direction is superconductors.
He previously taught at the University of Science and Technology of China, and Principal Dou, the president of Chen Yuanguang when he was a student at Jiangnan University, taught at the University of Science and Technology of China before he came to Jiangnan University. They have been teaching in the School of Physics for sixteen years and they are very familiar with each other
"Okay, no problem, let's go directly to the laboratory. The room-temperature superconductor is in the laboratory." Chen Yuanguang said.
Everyone went to the laboratory together. Chen Yuanguang took out the room-temperature superconductor and put it on a magnet for display. Chen Xianhui looked at the thermometer on the wall. It was 24°C, which was not much different from his body temperature.
But he still took out the temperature measuring instrument from the tool box and saw that the number on it was no different from the thermometer in the laboratory.
Chen Xianhui then put it back and continued to observe the normal temperature superconductor. His expression at this time was no different from that of the young people who saw it for the first time in Guangjia Aerospace.
In the past, he mainly worked on new superconductors, and his research directions spanned multiple superconducting systems, from cuprate superconductors, fullerene superconductors, iron-based superconductors, organic superconductors, etc.
Chen Xianhui recalled that more than thirty years ago, after he devoted himself to the research of superconductors, he fantasized more than once about what it would be like to make a room-temperature superconductor. As he gained a deeper understanding of superconductivity and grew older, his expectations became higher and higher. It is getting lower and lower, I just hope that I can make a breakthrough and achieve a breakthrough under the current conditions.
For example, the current highest superconducting critical temperature record under normal pressure is -139°C. If he can push this number forward to 138°C, he is already satisfied.
After seeing the news about LK99, Chen Xianhui was dismissive. The more he learned about superconductors, the less he believed that rods could produce room-temperature superconductors. This was also because he did not film Station B. He had a similar idea in his mind. Thought, if this were true, I would eat it.
Chen Xianhui received a call from the Natural Science Foundation of China when he was in the laboratory, asking him to prepare and fly directly from Hefei to Pengcheng on a special plane.
When he saw Weibo, even though it was posted by Chen Yuanguang, he still didn’t believe it was room temperature superconductivity. He thought it was low temperature, which was nothing more than raising -139°C to -80°C.
In the Guangjia Aerospace building, his body was telling him that the temperature was really only 24 degrees Celsius. This piece of material was suspended on the magnet. The entire piece of material was suspended. There was no one side that was trembling against the magnet and the other side was suspended.
When Chen Xianhui looked at Chen Yuanguang again, he felt like he was seeing a god. After more than thirty years of hard work, others could easily accomplish things that he could not even imagine.
"Guangshen, can I measure the resistance?"
Chen Yuanguang heard the pleading in the other person's tone, and he felt like he saw the other person's past knowledge collapsed, what you believed in No longer what you believe.
Chen Yuanguang nodded: "No problem, you can use the magnetometer and resistance meter here to measure it, or you can use your own.
In addition, take a look at this piece of material. There are two points marked on it. You can use those two points to measure the ideal value.
Because it is a one-dimensional superconductor with many impurities, similar to LK99. "
The reason why Chen Yuanguang said this is because Chen Xianhui just took out the equipment himself, and he thought that the other party was out of caution.
Chen Yuanguang's words are undoubtedly another fortress of Chen Xianhui's knowledge. The old man, who turned sixty this year, was a little unsteady.
"Okay" Chen Xianhui nodded
"One-dimensional superconductivity. It turns out that the one-dimensional superconductivity theory is true.
Such a niche theory is actually true. Does the Creator really exist? Are simple and beautiful rules the ultimate rules of the material world?" For a time, countless thoughts flashed through Chen Xianhui's mind, "So the one-dimensional superconducting theory proposed by Herbert is true?"
Chen Xianhui naturally would not think it as what the outside world thinks. The one-dimensional superconducting theory proposed by Korean Choi Dong-sik is regarded as the source of the entire system.
He has read far more literature than ordinary people and doctors. In his knowledge, the earliest one-dimensional superconducting theory came from the English physicist Herbert Freud in 1954. The paper "On the one-dimensional case of the theory of superconductivity" published by Roerich.
This paper was published in the 1154th issue of the "Philosophical Transactions" of the Royal Society. Chen Xianhui read Cui Dongzhi's paper on one-dimensional superconductivity that his students showed him.
The so-called ISB theory proposed by the Koreans, Chen Xianhui knew at a glance that this thing was based on Herbert and made some improvements.
It is precisely because he knows the origin of Cui Dongzhi's theory that he is even more dismissive of LK99.
After Herbert proposed it, one-dimensional superconductivity was cited more than a thousand times from 1954 to 2000. It is an old theory and has certain value for future generations of superconductor research. Played a guiding role. These concepts include the interaction between free electrons and lattice displacement, the lowest energy level required for sinusoidal lattice displacement in the system, the energy gap generated in the electron energy spectrum, the internal field role of periodic lattice displacement, etc. It is still being used today.
But this theory is not feasible. It has been quoted so many times. Countless attempts have been made based on this theory but no room temperature superconductivity has been achieved. The Koreans can just tinker with it. Take something out? impossible.
Chen Xianhui didn't even take advantage of the popularity and directly sentenced LK99 to death.
After seeing the room-temperature superconducting materials in the Guangjia Aerospace Laboratory, Chen Xianhui regretted extremely. When measuring the resistance, his thoughts had returned to that afternoon twenty-five years ago.
His memory was extremely clear. At that time, because a paper quoted Herbert's paper, he wanted to read the original text, and found the 1154th issue of the Journal of Philosophy in the old library of the University of Science and Technology of China. , saw Herbert's paper.
The memory has never been so clear. He ran his fingers over the yellowed and wrinkled book and found the specific page number from the table of contents.
I wish I had believed in this theory back then.
After measuring the resistance and confirming that it was indeed a room-temperature superconductor, Chen Xianhui had already organized his thoughts and completed his mental construction. So many people had not made anything based on Herbert's theory. How could I have made something at room temperature if it were me? Superconductors coming?
I chose this theory and became an academician. What else should I be dissatisfied with?
"There is no problem. It is definitely a room-temperature superconductor. There are no problems in terms of performance characteristics and measured resistance." Chen Xianhui gave his own judgment.
Bureau Wu took the lead in applauding. After he applauded, Lao Zhao followed suit, and then the entire laboratory burst into applause.
Chen Yuanguang felt that it was a bit silly to applaud himself. He sat on his chair and did not move. Then he thought about it and it seemed even more silly not to applaud.
"Okay, okay, very good!
Mr. Chen, the country is lucky, the nation is lucky! Please wait a moment, *** and *** are still waiting for news in ***, I will reply to them first We'll talk after another news," Bureau Wu applauded and walked towards Chen Yuanguang and said while shaking hands.
Bureau Wu went out to make phone calls. Chen Xianhui walked up to Chen Yuanguang. He had too many questions.
"Guangshen, I have some questions about room temperature superconductivity." Chen Xianhui said.
Chen Yuanguang thought that since Director Wu brought the other party, there must be no problem, "You don't have to be so polite, just call me Yuan Guang."
Chen Xianhui: "Okay, I'm not polite, just call me Lao Chen.
Yuan Guang, is your room temperature superconductor based on the LK99 theory?"
Chen Yuanguang laughed. : "Professor Chen, you are also a superconductor. Do you think you can burn it out?
This is like buying a lottery ticket. I choose 6 for all the numbers. In the end, my probability of winning is the same."
Chen Xianhui feels better now.
"We all know that superconductors rely on 100% diamagnetic volume. There is no magnetic field inside the entire material. It is impossible to burn it out by simply firing it.
Or maybe it can, and it is the same as winning the lottery or winning 1,000 bets in a row. The probability is equally low. I don’t think humans have such luck.
What’s more important is that this preparation method cannot be reproduced. It is a one-time product.
And we are here. Block GJ01 can be prepared repeatedly. Although it is a one-dimensional superconductor and faces many limitations and is difficult to apply, it is still a room-temperature superconductor. "
Chen Yuanguang named it GJ01 to distinguish it from LK99.
Chen Xianhui then asked: "Can I ask about the general preparation principle?"
Everyone who participated in this project at Guangjia Aerospace knew that he wanted to publish a paper in the future, and Chen Yuanguang felt that there was no need to keep it secret.
You know the principle, but you can’t make it if you don’t know the parameters.
"Professor Chen, have you ever heard of ExclusionZone?" Chen Yuanguang asked.
Chen Xianhui asked: "Is it a restricted area? I know its Chinese meaning, but if it is an academic term, I have not heard of it."
Chen Yuanguang disagreed. It was normal that he had never heard of it. After all, the other party was a professor of physics: "This is a biological concept.
Professor Gerald of Washington State University is committed to studying proteins and perfluorosulfonic acid. Properties of water at the surface.
He discovered a new structure of water molecules that he called ExclusionZone water, which has the ability to exclude all solutes from it.
The structure of ice. It is a three-dimensional, hexagonal structure arranged in a honeycomb shape, and the layers are connected together by oxygen atoms.
As the ice melts, the oxygen atom bonds weaken and shift laterally, forming hydrogen. Electrostatic bonds between atoms and oxygen atoms
This gives the structure the ability to have rotational symmetry and lateral translation, allowing it to form any three-dimensional structure, especially spirals, where this water forms in sheet-like structures.
Since a superconductor must show 100% diamagnetism and there must be no magnetic field in the body, and ExclusionZone water can exclude all solutes, does that mean that this structure helps to form a normal temperature superconductor?
I have no idea of how to achieve a multi-dimensional structure, but for a one-dimensional structure, we can completely use N-MDCV magnetic field control technology to directionally control materials like LK99, so that its poles can flow and rotate. The direction is exactly the same.
The phase differential ratios at the North Pole and South Pole are arranged according to a certain ratio, so that phase compression at the North Pole and phase expansion at the South Pole can be achieved.
This vortex naturally generates the Larmor precession frequency that causes vibration within the three-dimensional magnetic structure, thereby building diamagnetism similar to ExclusionZone water. ”
Chen Xianhui regretted that he did not bring a notebook and pen to write down what Chen Yuanguang said. It involved too many new concepts that he had not been exposed to before.
"Simply put, first use the preparation method of LK99 to transform the modified lead apatite crystal structure, and then use magnetic field manipulation to change its internal magnetic field, so that it can achieve 100% diamagnetism." Chen Yuanguang concluded. .
Technical principles are not important, just like everyone knows the principles of photolithography machines, but only ASML can build photolithography machines.
Similarly, everyone knows about magnetic field control. Chen Yuanguang has cleared all the data on how to set up the specific magnetic field control. Only he knows this set of setting rules.
Or if someone else can go to the future to check the information, he can also know.
An embarrassed smile appeared on Chen Xianhui's face after he understood: "Yuan Guang, I roughly understand it. I don't know if what I said is right. The preparation method you designed is not much higher than the probability of buying a lottery ticket, right?"
Continue tomorrow, please vote for me!
