Chapter 247 132K! Major results! Yan Shiqing: Looks like we can’t wait until next week!
Xihai City.
Temporary experimental group of Superconducting Materials Research Center.
Everyone who participated in the experiment was very active. They continued to discuss the research results during the work. The material with a superconducting transition temperature of 119K was really amazing and made them all feel incredible.
"It's actually 119k. This kind of material can be directly used in industry, right?"
"Support the creation of a superconducting maglev train, there is no problem!"
"And the main thing is that the manufacturing process is not complicated and large-scale production can definitely be achieved. We have developed material technology that changes the world!"
When this topic was brought up, everyone became energetic because they had just finished the experimental research and they all had less work to do, but they still felt energetic.
The same is true for Deng Huanshan.
He understands very well the concept of 119k superconducting materials that can be used in industry.
Now he is convinced of Wang Hao. When he thinks of the materials he has researched, he can't help laughing. When talking about work with other people, his face is not even a little serious.
Instead, Deng Huanshan began to worry about the old academician Yan who had 'airborne' over.
Academician Yan Shiqing was designated by the Department of Science and Technology as the research director. It doesn't matter if he is the research director. A top academician in the field of superconducting materials is indeed enough.
However, Academician Yan looks very impressive, and he has not been to Xihai for such a long time.
Now that they have achieved results, and they are very big results, Deng Huanshan is a little worried that Academician Yan will suddenly come to take the credit.
However, thinking that it was Wang Hao who was mainly controlling the experiment, Deng Huanshan felt that he was thinking too much.
Steal Wang Hao's credit?
joke!
Although Wang Hao is only the deputy director of the research center, everyone knows that he is much more important than the director. It is even said that as long as Wang Hao speaks, the director may leave immediately.
This is powerful personal influence.
After the research yielded results, Wang Hao would come to the experimental group every day. The first task he assigned was to create more new materials.
Wang Hao explained to Deng Huanshan, "New materials need to be tested in detail, not only the superconducting temperature and elemental composition, but also used in AC gravity experiments to detect the specific topological properties of the materials."
The latter is very important.
The research is based on semi-topological theory. Any valuable material research must conduct experiments related to AC gravity to detect the 'topological state' of the material.
This is very important for perfecting the semi-topological theory and for subsequent research.
Through the exchange of gravity experiments, the topological structure of a part of the material can be completed, which can be used as a breakthrough to continue subsequent research.
Wang Hao is also a little worried, "Although the progress is very fast now, we still have to do the research step by step. Our computing team can no longer keep up with the progress."
This is the main problem that limits research.
Although materials with a transition temperature of 119k have been produced, in fact, they have been unable to shape the topological properties of the new material.
To put it simply, it is impossible to complete the micro-morphological geometry shaping work inside the new material, and subsequent research will lose theoretical support.
The algebraic geometry working group’s calculations simply cannot keep up with the research progress.
In this regard, Fu Xiangdong made a work report.
"We have now analyzed the superconducting transition temperatures corresponding to eight dual-element combinations."
"Each group is a combination directly related to experimental research, but the analysis and calculation work of two-element combinations is still far from enough."
"We need more data base to be able to analyze the relationship between element combinations in a more detailed manner."
In this experiment summary meeting, not only Fu Xiangdong participated, but also He Yi and Liu Yunli, who represented the exchange gravity experiment group.
The AC gravity experiment group mainly cooperates with AC gravity-related detection to provide data support for the algebraic geometry group and theoretical analysis.
Wang Hao called all the core personnel together to discuss the support that the theory could provide for application, but the final result was not very good.
The current theory has obviously failed to keep up with the research progress.
Just like what American said, they need to first complete the database of superconducting transition temperatures corresponding to dual element combinations before they can conduct further research on applications.
Now they have completed material research beyond theoretical support.
This means that theory can no longer provide much help.
Wang Hao felt a little disappointed. He hoped that the research could continue step by step instead of stagnating for some reason.
Of course, progress can still be made in materials research. Even without theoretical knowledge, they can improve the process, that is, adjust and improve the material preparation process.
Therefore, Wang Hao continued to stay in the experimental group and participated in the research on material preparation.
soon.
Wang Hao organized the second experimental demonstration.
The difference between this experimental demonstration and the last time is that everyone who participated in the meeting spoke actively and expressed their opinions enthusiastically. It can be seen that their mental outlook will be different from last time.
On the second day, Wang Hao made another summary, wrote some process adjustment strategies, and handed them over to Deng Huanshan to be responsible for the experiment.
Then, just wait.
…
Five days later.
While Wang Hao was sitting in his office, patiently guiding Qiu Hui'an in sorting out the proof, Deng Huanshan sent a message saying that new materials had been prepared through research.
"Both materials look pretty good."
"One color is heavier than last time, but I feel better than last time; the other one is a little worse, but it is also valuable."
Deng Huanshan made a simple evaluation of the newly prepared materials.
Wang Hao still patiently gave Qiu Hui'an guidance, telling him how to organize the proof process, and also talked about some paper formats and other content.
After that, he went to the superconducting material experimental group and saw the two materials Deng Huanshan mentioned.
These two newly prepared materials are still thin film materials. There is only a thin layer in the container. There is one silver material that is brighter than the last time, and the other one is a little darker in color.
"I think the one with a bad color is better," Deng Huanshan said. "According to my experience, the bright color indicates a high metal content, but on the other hand, the superconducting critical temperature may be lower."
Wang Hao nodded slightly as he listened.
Because the material has just been prepared and its properties are still very unstable, there is no way to directly test it.
He found the preparation process and looked at it naturally, and made an estimate in his mind. Just like Deng Huanshan said, the superconducting critical temperature of silver shiny materials may be relatively low.
This does not mean that the application value of the material is small, but it may be higher.
When the metal content of the material is higher, the upper limit of the current intensity it can generally carry will be much higher.
The current in a superconductor is not infinite.
According to Ohm's law, the current is infinite without resistance. However, the superconducting state is limited by the power. In addition, each superconducting material has an upper limit for carrying current.
Therefore, most organic superconductors and gas element superconductors generally cannot be used industrially.
This time it took a long time to wait for the properties of the new material to stabilize. It was not until the afternoon of the next day that the staff reported that it could be tested.
Wang Hao immediately went to the experimental group again, and then stood with Deng Huanshan to observe the testing work.
The detection of superconducting transition temperature of new materials is a very simple process, especially when the transition temperature is still above 100k, and only cooling with liquid nitrogen is enough.
After the detection officially started, many people kept paying attention to the values on the detection instrument. When the superconducting transition occurred, the values on the detection instrument would stop.
They all have expectations in their hearts.
Most of the previous research on the detection of superconducting transition temperature has brought no surprises, but now they are all looking forward to this moment.
The same goes for Deng Huanshan and Wang Hao.
The expressions of the two people are different.
Deng Huanshan's face was full of nervousness and anticipation, and he kept saying, "It doesn't need to be too high, it just needs to be higher than the last time."
His voice was trembling a little.
The last transition temperature was 119k. If it is higher than 119k, it will naturally reach or exceed 120k.
It turns out that the transition temperature of 120k does not have any special meaning. However, after the news reports about Amerikan's investment in superconducting materials, the whole world focused on this transition temperature, and 120k has a special meaning, which means
Can be put into industrial use.
In fact, a transition temperature exceeding 100K can actually be used in many fields.
American has set the goal of 120k, which gives the 120k transition temperature a special meaning. It represents the goal that American's large research team has worked hard to achieve in three years.
Now it seems they are about to make it happen!
Deng Huanshan was very excited just thinking about it, and so were everyone else.
Everyone’s eyes are fixed on the values on the testing instrument.
150k……
140k……
135k……
The value drops little by little.
When it dropped to 132k, the instrument pointer slowly stopped, but others did not shout out and continued to watch the pointer to see if there was any change.
One second, two seconds, three seconds...
At the fifth second, someone finally couldn't help shouting, "132K!"
"Stop it! 132k!"
"It's over 130k... 132k! This is awesome!"
Everyone involved in the testing discussed excitedly.
Everyone said excitedly.
The same goes for Deng Huanshan, "132k! Not only did we achieve the goal of preparing 120k materials, we also far exceeded it..."
"good!"
Wang Hao also took a deep breath and made one more comment with a smile.
This data is similar to what he expected. There is no surprise of 'exceeding expectations' last time, but it is indeed worth being excited to reach more than 130k.
soon.
Another shiny material was also tested, and it was similar to Deng Huanshan's judgment. The transition temperature was slightly worse than the dull one.
The final result was 121k, which was just barely over 120k.
However, both Deng Huanshan, Wang Hao, and others in the experimental team all agreed that shiny new materials are much more valuable than dim ones.
Of course, the specifics still depend on the test results.
…
Regarding the research results of the newly prepared materials, the superconducting materials experimental team made a confidential report.
The Science and Technology Department quickly received the news.
The Superconducting Material Experiment Group is a research team directly under the Science and Technology Department, and the confidential report on the research results was directly handed over to Zhao Enshun's desk.
Zhao Enshun was surprised when he received the news. He even checked with his secretary, "Superconducting material experimental group? From Xihai? Yan Shiqing?"
The secretary nodded and confirmed the news.
"Didn't Yan Shiqing just take office? How come there are results?" Zhao Enshun was a little confused, but he still opened the file and looked at it carefully.
I was shocked when I saw it.
Two new iron-based superconducting materials, one with a higher metal content and a transition temperature of 121k, and the other with a lower metal content and a transition temperature of 132k?
Are you kidding me?
Zhao Enshun rubbed his eyes vigorously and read it carefully several times before confirming the content. He suddenly felt that his mind went blank. It took him a long time to turn around and quickly called several responsible personnel.
These include Zhu Bin, deputy director of the Science and Technology Department, Duan Xingguo, head of the Materials Department, and Xu Baogong, Zhou Minhua and others from the Science and Technology Bureau.
A group of people gathered together.
Zhao Enshun spoke of the new news in a shocked tone, and then others also became shocked, "Minister Zhao, are you kidding?"
"Yan Shiqing has just passed by, right? Now he has achieved results? And, 132k superconducting material?"
"Could it be someone else? I know Deng Huanshan, he has passed away long ago."
"It should be related to Wang Hao, right?"
"The submitted documents only mentioned the results, but did not mention the specific people involved, but the results must have been there, and it is impossible for them to make such a mistake."
"This achievement is too significant and too sudden..."
Many people feel the same way.
Although the research direction of superconducting materials has been determined and a large amount of funds are planned to be invested, it is still in the process of 'preparation'.
Even if funds have been prepared, the funding must be reviewed step by step according to the content of each project. The Superconducting Materials Research Center in Xihai is the first big project. Even the research center is still in the process of construction. The director of the research center must be selected.
It was just finalized last month.
At this time, it was suddenly said that such a significant achievement had been achieved, which really caught people off guard.
Some time ago, American announced a major investment in the research of superconducting materials. The largest experimental research center announced that it would work hard to create superconducting materials with a transition temperature exceeding 120K that can be used in industry within three years.
However, the research there has only just begun. It is even said that it is still being planned and has not really started.
As a result, they have been manufactured?
"I think we need to go and see this result with our own eyes before we can confirm it." Zhou Minhua suggested, "Go and see how it was done, and talk with Professor Wang Hao and Academician Yan Shiqing..."
"Yep!"
"Such a significant achievement is incredible!"
"Even if you are facing a submitted document and you don't know the specific situation at all, you still have to take a look at it and then discuss and make a decision."
Zhao Enshun asked, "Waiting for other news?" He was referring to the subsequent report content.
When the research has significant results, the results will first be reported, and then a summary will be made to write a detailed research process, including reporting on the personnel involved in the research and their contributions.
It will definitely take some time for subsequent content to be reported.
"Can't wait any longer!"
Xu Baogong supported Zhou Minhua's idea, "Such a significant achievement can be said to change the world and can be applied in too many fields. Let's just go and take a look and know the specific situation."
"If we are waiting to submit documents, how long do we have to wait? This kind of research is very complicated. What if something goes wrong in the middle?"
Others also thought it made sense. They were shocked when they heard the news and felt that they should go and see it with their own eyes.
Zhao Enshun listened to everyone's opinions and decided to immediately organize manpower to go to the experimental group in Xihai to have a look.
The impact of this result is too great.
Anyone who has done some research on superconductivity will know the concept of superconducting materials above 120k that can be used in industry.
That's really world-changing technology.
To give the simplest example-electricity storage technology,
Superconducting electromagnetic energy storage technology has been demonstrated by professional institutions around the world. Simply put, the technology uses superconducting coils to store electrical energy.
The most famous of them is American Ebaco Service Company and Bechtel National Corporation, a new type of electrical energy storage technology researched by American Domestic Defense Strategic Defense Planning Agency and Defense Nuclear Weapons Agency.
The manufacturing plan they gave is to input power into a superconducting coil the size of a football field when there is not much electricity.
The coil is made of niobium-titanium alloy and immersed in a deep pit filled with liquid helium.
When electric current circulates in a superconducting coil, a magnetic field is formed around the coil, thereby storing electrical energy in the form of magnetic energy.
The superconducting material used in this solution is niobium-titanium alloy, and the superconducting transition temperature of niobium-titanium alloy is only about 8k to 10k.
Such a low temperature requires a liquid helium environment, and there is no doubt that the cost is very huge.
If new materials are used as superconducting materials, then it is enough to soak the superconducting coil in a liquid nitrogen environment. Liquid nitrogen is relatively very cheap. The cost and maintenance of the manufactured superconducting power storage device are
It will be extremely reduced, and there is definitely a possibility of implementation.
The 21st century is dominated by energy, and it is very difficult to store large amounts of electrical energy.
Most of the electric energy is used as soon as it is produced, and the unused part is wasted. This results in sufficient electric energy in some seasons and insufficient electric energy in other seasons, and is also affected by other facilities.
If there is a large-scale device for storing electrical energy, excess electricity can be stored and the problem will be perfectly solved.
…
Academy of Sciences, Institute of Mathematics.
Recently, Yan Shiqing has been visiting the Institute of Mathematics frequently. He hopes to persuade more algebraic geometry experts to work in Xihai.
The results of his work are also very significant and have convinced five scholars in the field of algebraic geometry.
Yan Shiqingzheng and Meng Guosheng said, "Guosheng, if you work over there in the West Sea, you will not only be able to participate in the most cutting-edge research, but you can also make more money!"
"Think about it, what can you do in mathematics? With such a small salary per year, when we do research, it sounds like we are scientists, but the institute really can't retain people."
"If I go there and participate in big projects, the subsidies will be huge, and it won't be a job change. I'll still be at the Mathematics Institute. I can apply to my superiors. It's a temporary job transfer."
Meng Guosheng is forty-five years old, a researcher at the Institute of Mathematics, and one of the top figures in the field of algebraic geometry in the Institute.
Because of this, Yan Shiqing focused on 'tackle' Meng Guosheng.
Meng Guosheng was already very excited.
If he had been ten years younger, he would have followed him to Xihai without hesitation, but now that he has a family and no job in Feicheng, it would definitely be inconvenient to go to Xihai to work.
But considering the salary issue, he was still very excited.
As an ordinary researcher at a mathematics institute, he only earns hundreds of thousands a year, while some of his Ph.D. classmates go to work in companies, and some already earn millions a year.
The difference is really huge.
"If I go to the West China Sea, how much more money can I get?" Meng Guosheng is concerned about this issue.
Yan Shiqing immediately grinned. He knew that Meng Guosheng was moved, so he continued, "At the lowest, I can get an extra 50,000 or 100,000 yuan. There will be no problem. Not to mention doubling the salary, there will definitely be a substantial increase."
In fact, he doesn't know exactly how much more he can get, but there must be subsidies for big projects.
Meng Guosheng hesitated and said, "I'll discuss it with my family when I go back."
Yan Shiqing was very happy after convincing Meng Guosheng. He went alone and always felt alone. Going with a few algebraic geometers would give him more confidence.
As he was walking back, he received a call from Wu Hui.
Yan Shiqing frowned, but still answered the phone and asked, "Old Wu, what's wrong?"
"Have you gone to Xihai?" Wu Hui on the other end of the phone was a little anxious.
"No ah?"
"Why haven't you passed yet?"
"It's coming soon." Yan Shiqing frowned and said, "I'm looking at the time. It will be there next week. It will only be the 15th until next Monday."
He said and shook his head.
It was originally planned to go by the end of the month, but Wu Hui kept urging him, so he decided to move it a little earlier.
Wu Hui's reaction was a bit unexpected. He seemed to sigh, and then said, "I think you can carefully consider whether to go to the West Sea."
"Why?"
"this……"
Wu Hui did not say it directly, but said, "Anyway, you should think about it. You are already 63 years old. It would be good for you to wait for retirement at the Academy of Sciences."
"……what do you mean?"
"For your own good!"
"For my own good? Not letting me go? Such an important research?"
Yan Shiqing's tone was bad as he spoke.
They had been urging him to go there before, but now they suggested that he give up his job and stay at the Academy of Sciences until he retires?
After Yan Shiqing put down the phone, he felt very angry just thinking about it. He thought about it carefully and suddenly felt a sense of urgency, "I'll make a report when I get back and submit the names of Meng Guosheng and several others!"
"Looks like we can't wait until next week, we'll be there on Thursday and Friday!"
He thought, "Someone must be interested in the position of director of the research center, otherwise Wu Hui wouldn't have said that!"
