After chatting for a while about the arrangement of room temperature superconducting materials, Yuan Zhouli picked up the porcelain cup and took a sip of warm tea, moistened his throat and looked at Xu Chuan.
"Academician Xu, what do you think about the questioning of room temperature superconducting experimental data by materials research institutes in various countries?"
Less than two days after the copper oxide-based chromium-silver system room-temperature superconducting material was published on Arxiv, the academic community is already making a fuss.
Although some countries with bad intentions are involved in this matter, it is enough to illustrate Xu Chuan's status in the academic world.
Only he can make such public achievements impact the whole world so quickly.
In fact, in the final analysis, governments are afraid.
Because Xu Chuan's reputation and status in the academic world are far from comparable to those in South Korea.
Even if the published room temperature superconducting materials have obvious problems in experimental data, countries are still afraid that this is true.
So I can't wait to confirm the situation of room temperature superconducting materials through academic questioning and some means, and to obtain some other things.
Hearing this question, Xu Chuan didn't think much. He said, "Let's follow the high-temperature copper-carbon-silver composite superconducting material last time."
"However, Oak Ridge National Laboratory, NASA, California Nanotechnology Institute (CNSI)...these are the ones that are leading the trouble and are on the blacklist and do not provide copper oxide-based chromium-silver series room temperature superconducting materials."
Superconducting materials, whether they are high-temperature superconducting materials or room-temperature superconducting materials, will eventually be used.
In other words, it is actually used to make money. Whether it is sold domestically or exported abroad, the ultimate goal is to make money.
Of course, unlike other materials, room temperature superconducting materials are very important to the development of science and technology, so their incidental value is also extremely high.
Therefore, making money from exports has become an incidental attribute.
For a country, making money is undoubtedly secondary if it masters this time-honored material, and its main attribute is to trade it for various things that cannot be traded with money.
For example, some cutting-edge technologies, photolithography machines, semiconductor-related technologies, etc.
These things still have a lot of shortcomings for China, and they are basically prohibited from sale and export by other countries.
Room temperature superconducting materials can be used in these fields.
Exchanging materials for technology and equipment, even if they are sub-cutting edge, is only possible with this kind of cross-generational material.
After all, one is fish and the other is fishing, and the two are completely different.
And to put it another way, what some netizens said is actually not a problem.
If it is in some other fields, falling into the self-proof trap is the stupidest behavior.
But in academia, questioning is a basic rule of academics, and self-proof is also a basic rule. A scholar has the responsibility and obligation to prove the correctness of his research results to the outside world.
Just like mathematics, every proof of the world's difficult Millennium Conjecture needs to pass the review of the mathematical community and hold academic conferences to explain the doubts of many mathematicians.
In the field of materials science, things like room temperature superconducting materials will undoubtedly also need to be verified by the outside world.
Maybe some people think that it doesn't matter if you don't explain it, as long as you really use the materials yourself.
But for academia, academic reputation is also an important part of being a scholar.
Isn't it because of Xu Chuan's academic reputation that the reason why this time's room temperature superconducting material has attracted the attention of countries all over the world so quickly?
Therefore, it is certain and necessary to prove to the outside world the reality of room temperature superconducting materials.
Similar to high-temperature superconducting materials, the best way is to mail a copy of the material to other research institutes and complete testing experiments.
This is actually the purpose of these materials laboratories and research institutes that speak out.
Obtaining the preparation method is impossible to figure it out with your toes, but it is still possible to obtain a piece of room-temperature superconducting material for research.
But this kind of approach with obvious political factors makes Xu Chuan a little disgusting.
Therefore, these materials research institutes and laboratories are directly excluded.
There are so many materials research institutes and laboratories in the world. Having a few more of them is not a big deal, and a few of them being less is not a big deal either.
It is said that it is never too late for a gentleman to take revenge, but he never considers himself a gentleman. He is a villain. For this kind of thing, the sooner he can be slapped back, the better.
Don’t you want to use public opinion to force me to give you room temperature superconducting materials to verify that the experimental data is OK?
Hey, I just won’t give it to you, what’s wrong? Others can’t verify it, right?
Opposite the sofa, Yuan Zhouli nodded and thought for a moment, then said with a smile: "Academician Xu, I have a suggestion regarding the verification of room temperature superconducting materials."
Xu Chuan looked over and asked curiously: "How do you say it?"
Yuan Zhouli thought for a moment, organized his words, and then said: "My idea is very simple. Instead of sending the materials out for others to study and test, it is better to invite people from the other party to come over and verify them in China."
Hearing this suggestion, Xu Chuan frowned and said, "Do you want to prevent room temperature superconducting materials from flowing out?"
Yuan Zhouli nodded. He did have this idea, but there were other reasons that he couldn't say here.
Xu Chuan shook his head and said: "The outflow of room temperature superconducting materials is inevitable. This cannot be avoided unless we don't use it and don't produce it."
"As long as industrialization is realized, it will be easy for other countries to obtain the materials after they are produced in small batches without even industrial application.
"It's basically impossible to keep confidential information from being leaked. To be honest, it's not of much use."
Yuan Zhouli smiled and said: "It doesn't matter, it's impossible to keep it secret forever, but we can keep it secret for a while, and that's enough."
Xu Chuan: "In that case, let's do it according to Yuan Qian's wishes."
To be honest, he doesn't really agree with this approach of wanting to keep room temperature superconducting materials secret before large-scale applications.
It is inevitable that other countries or laboratories will obtain room temperature superconducting materials, and it is impossible for room temperature superconducting materials not to be used.
And as long as it is applied, it is easy for other countries to obtain it.
Just like a high-precision chip, as long as you apply it commercially and sell it to others, it is easy for others to get it.
But is it useful to get the chip? It is useless. The photolithography machine and a series of processing methods are the real secrets.
The same goes for materials, so the confidentiality method of preventing a material that is to be commercialized from leaking out is meaningless in his opinion.
He has actually kept the secret secret. What he has disclosed is only the basic papers. The preparation technology and methods are all "black box", and these have not been made public.
And reverse development of products has never been easy, especially in the field of materials.
If it were really easy to reverse engineering, would domestic research and development in the field of materials have lagged so far behind over the years?
Will not.
Therefore, confidentiality in the field of materials has never been achieved by not leaking materials, but by continuous research and development and continuous improvement of material performance.
But since Yuan Geng proposed to keep it secret for a short time, he would not refute it.
Maybe he may have some other thoughts or ideas.
Xu Chuan doesn't pay much attention to this kind of thing, and it's not a problem if he cooperates with the work.
Hearing this, Yuan Zhouli also had a relieved smile on his face: "I will arrange for someone to cooperate with the Sichuan-Hai Materials Research Institute to complete this matter."
Xu Chuan nodded and said, "Okay, these are all small things."
Yuan Zhouli smiled and said, "Thank you for your understanding."
After a pause, he continued: "In addition, when I come here this time, there is one more thing I want to ask you."
Xu Chuan: "What happened?"
Yuan Zhouli organized his language and said: "It is also related to room temperature superconducting materials. Regarding this material, I believe you are also very aware that its applications in various cutting-edge scientific and technological fields are very important. We would like to ask, what is it?"
Is there enough potential to make superconducting coils, electromagnetic guide rails, etc.?"
Xu Chuan glanced at Yuan Gen and asked with a smile: "You want to ask about electromagnetic rail guns, right?"
Yuan Zhouli was not embarrassed at all because his thoughts were seen through. He nodded with a smile and said: "National defense technology is also technology. They are all important. They are all important."
Xu Chuan smiled and said, "Actually, you are not the first to ask this question."
After thinking for a while, he continued: "How should I put it? Putting aside its brittleness and vulnerability, copper oxide-based chromium-silver system room-temperature superconducting materials are more suitable for electromagnetic rail guns than high-temperature copper-carbon-silver composite superconducting materials.
These."
"The intensity of three standard atmospheres is not high, it is easy to achieve, and it is also easy to apply to technologies such as electromagnetic rail guns."
"But it's still an old problem. We can't put aside the brittleness and fragility. You know, the application environment of this kind of weapons and equipment is often very harsh. This can't be put aside."
"So currently, it is very difficult to apply it to national defense weapons such as electromagnetic rail guns and Gauss rifles."
This is actually a common question. When the high-temperature copper-carbon-silver composite superconducting material was developed last time, Qin Anguo, the previous chief of science and technology, also asked him about this.
His answer was similar.
Yuan Zhouli thought for a while and asked tentatively: "In other words, as long as the two problems of brittleness and fragility of room temperature superconducting materials can be solved, is it possible to apply it to these national defense technologies?
"
Xu Chuan nodded and said: "Theoretically, you can say this, but I can't guarantee you how long it will take to solve these two basic problems."
Compared with high-temperature superconducting materials, room temperature superconducting materials are still making progress in the application of weapons and equipment such as electromagnetic rail guns and Gauss rifles.
At the very least, the intensity of three standard atmospheres is more suitable for these technologies than the low temperature of 152K.
It does not require cooling by things like liquid nitrogen and liquid helium. Raising the pressure faced by the material to above three standard atmospheres can be achieved by increasing the force, reducing the area of action, optimizing material selection and structural design, etc.
To put it simply, if the two key issues of brittleness and fragility can be solved, then room temperature superconducting materials can theoretically complete miniaturized electromagnetic rail guns and electromagnetic coil guns.
That is, small but highly lethal weapons such as Gauss rifles and electromagnetic rifles in science fiction movies can be created.
Because it has enough miniaturization foundation, it no longer needs to drag a huge cooling device to lower the temperature of superconducting materials.
Upon hearing this answer, Yuan Zhouli's eyes lit up and his heart became active.
Although Xu Chuan said he didn’t know how long it would take to complete the subsequent optimization, there is at least hope, right?
Compared with high-temperature superconducting materials, room-temperature superconducting materials are a huge improvement.
When he goes back, he must communicate with his superiors. The cost of authorizing room temperature superconducting materials must be compensated more!
...
In the office, after dealing with matters related to room temperature superconducting materials, Mr. Yuan stood up and left.
It's not easy to find time to come here today. He has many other things to do.
As for Academician Zhang Pingxiang, he has no plans to leave Jinling anytime soon.
He not only wanted to see how Xu Chuan prepared copper oxide-based chromium-silver system room temperature superconducting materials, but also wanted to see those unpublished papers, and also wanted to participate in the subsequent optimized research and development of room temperature superconducting materials.
Xu Chuan readily agreed to these requests.
When the high-temperature copper-carbon-silver composite superconducting material was optimized last time, Academician Zhang participated and had rich experience.
how to say.
In a word, the labor force of free prostitutes is brought to the door by oneself. Isn’t that delicious?

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The next day, in Xu Chuan’s office at Sichuan-Hai Materials Research Institute.
After reading the complete version of the paper "Condensed Matter Electron Localized Structure Theory" in his hand, Zhang Pingxiang breathed a long sigh of relief, looked at Xu Chuan with shining eyes, and said.
"A very exquisite paper. I never thought that there would be such a path in the field of materials science."
Xu Chuan smiled and said: "The application of electron delocalization is not only used in room temperature superconducting materials, but also has broad application prospects in other materials."
"It can greatly optimize some properties of materials and is worthy of in-depth study."
Academician Zhang Pingxiang nodded seriously and said: "I think so too, so I have an idea that needs your approval."
"What do you think?" Xu Chuan asked curiously.
Zhang Pingxiang organized his language and said: "To put it simply, your paper has great potential. It is enough to open up a new discipline in the field of materials science."
"I want to sort out this part of the stuff and compile a textbook in the field of materials science for students in the field of materials science to learn and research."
Hearing this, Xu Chuan glanced at Academician Zhang in surprise and saw that his expression was serious, not like he was joking.
"Write a book and talk about it~"
Taking a deep breath, Xu Chuan leaned back in his chair and sighed, with some unclear meaning.
For Chinese people, this is probably the highest level of a scholar.
