Xihai City.

Temporary Experimental Group of Superconducting Materials Research Center.

Everyone involved in the experiment was very active, and they continued to discuss the results of their research in the process of work, and the material with a superconducting transition temperature of 119K was really amazing, and they all felt incredible.

"There can be 119K, this material can be directly applied to industry, right?"

"Support the manufacture of a superconducting maglev train, there is no problem!"

"And the main thing is that the manufacturing process is not complicated, it will definitely be able to achieve large-scale production, and we have developed materials technology that will change the world!"

When it came to the subject, everyone became energetic, because they had just finished their experimental research, and they all had little work to do, but they still felt energetic.

The same is true for Deng Huanshan.

He understands too well what the concept of 119k can be used in industrial superconducting materials.

Now that he is convinced of Wang Hao, he can't help but laugh when he thinks of the materials he has researched, and when he talks about work with others, he doesn't even have a little seriousness on his face.

Deng Huanshan began to worry about the old academician Yan who 'parachuted' over.

Academician Yan Shiqing was designated by the Science and Technology Department to serve as the research director, and 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 seems to be very powerful, and he has not been to Xihai for so long.

Now that they have achieved results, and they are great achievements, Deng Huanshan is a little worried that Academician Yan will suddenly come over to grab the credit.

However, thinking that it was Wang Hao who mainly controlled the experiment, Deng Huanshan felt that he was thinking a little too much.

Robbing 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, and even said that as long as Wang Hao speaks, the director may go down immediately.

That's what makes a strong personal impact.

After the research results, Wang Hao would come to the experimental group every day, and the first task he explained was to make more new materials.

Wang Hao explained to Deng Huanshan, "New materials should be tested in detail, not only for superconducting temperature and element composition, but also for AC gravity experiments to detect the specific topological properties of materials." ”

The latter is very important.

The research is based on the semi-topological theory, and any valuable material must be studied by alternating gravity to test the 'topological properties' of the material.

This is important for the refinement of the semi-topological theory, as well as for subsequent research.

Through the AC gravity experiment, a part of the topological architecture of the material can be completed, which can be used as a breakthrough to continue subsequent research.

Wang Hao was also a little worried, "Although the progress is very fast, we still have to wait for the research to come step by step." Our compute team can't keep up. ”

This is the main problem that limits research.

Although materials with a 119K transition temperature have been manufactured, in practice, they are no longer able to shape the topological properties of the new materials.

To put it simply, it is impossible to complete the microscopic geometry shaping inside the new material, and the subsequent research will lose theoretical support.

Algebraic Geometry Working Group, computation simply can't keep up with the progress of research.

In this regard, Fu Xiangdong made a work report.

"We have now analyzed the superconducting transition temperatures corresponding to the eight two-element combinations."

"Each group is a combination directly related to experimental research, but the analysis and calculation of the two-element combination is still far from enough."

"We need to have more data base to be able to analyze the relationship between the combination of elements in a more granular way."

In this experimental summary meeting, not only Fu Xiangdong participated, but He Yi and Liu Yunli also participated, and they were representatives of the gravity experiment group.

The AC gravity experimental group is mainly used to cooperate with the AC gravity related detection to provide data support for algebraic geometry groups and theoretical analysis.

Wang Hao gathered all the core personnel together to discuss the support that the theory can give to the application, but the final result was not very good.

The current theory has clearly not kept up with the progress of research.

As Amriken said, they need to improve the database of superconducting transition temperatures corresponding to the combination of two elements before they can proceed to the next application research.

Now they have completed the research on materials beyond theoretical support.

As a result, theories are no longer of much help.

Wang Hao felt a little disappointed, he hoped that the research could continue step by step, rather than stagnate for some reason.

Of course, there can still be progress in material research, even if there is no theoretical knowledge, they can make improvements in the process, that is, in the preparation process of materials.

Therefore, Wang Hao continued to stay in the experimental group and participated in the research of material preparation.

Soon.

Wang Hao organized the second experimental demonstration.

The difference between this experiment and the last time is that everyone who participated in the meeting actively spoke and enthusiastically expressed their opinions, and it can be seen that their mental outlook will be different from last time.

The next day, Wang Hao made a summary, wrote some process adjustment strategies, and handed it over to Deng Huanshan to be responsible for the experiment.

Then, just wait.

……

Five days later.

When Wang Hao was sitting in the office, patiently guiding Qiu Hui'an to sort out the content of the certificate, Deng Huanshan sent a message saying that new materials had been prepared through research.

"Both materials, they look pretty good."

"There's a color that's a little heavier than the last time, but I feel even better than the last time; The other is a little worse, but there is also value. ”

Deng Huanshan made a simple assessment of the newly prepared material.

Wang Hao still patiently instructed Qiu Hui'an, told him how to sort out the proof process, and also said some content such as the format of the paper.

After that, he went to the superconducting materials experimental group and met the two materials Deng Huanshan said.

The two newly prepared materials are still thin film materials, and there is only a thin layer inside the container, one silver material, which is brighter than the last time, and the other is a little darker.

"I think the one with the poor color is better." "In my experience, the bright color indicates that the metal content is high, but the superconducting critical temperature may be lower. ”

Wang Hao listened and nodded slightly.

Because the material has just been prepared, the properties are still very unstable, and there is no way to directly detect it.

He still found the preparation process and looked at it naturally, and made an estimate in his heart, just like Deng Huanshan said, the critical temperature of superconductivity may be relatively low for silver shiny materials.

This does not mean that the application value of the material is small, but it may be more valuable.

When the metal content of the material is higher, the upper limit of the current intensity will be much higher.

The current in superconductivity is not infinite.

According to Ohm's law, the current is infinite without resistance, however, the superconducting state is limited by the power, and in addition, every superconducting material has an upper limit on the current it can carry.

Therefore, most organic superconductivity and gaseous element superconductivity are generally not available for industrial use.

This time, it took a long time to wait for the new material to stabilize its properties, and it was not until the afternoon of the next day that the staff reported that the test could be carried out.

Wang Hao immediately went to the experimental group again, and then stood with Deng Huanshan to watch the testing work.

The detection of superconducting transition temperature of new materials is a very simple process, especially if the transition temperature is above 100K, it only needs to be cooled with liquid nitrogen.

When the test officially begins, many people have been paying attention to the value on the detection instrument, and when the superconductivity transition occurs, the value on the detection instrument will stop.

They all have expectations in their hearts.

Most of the previous studies have not brought surprises in the detection of superconducting transition temperatures, and now they are looking forward to this moment.

The same goes for Deng Huanshan and Wang Hao.

The expressions of the two were different.

Deng Huanshan's face was full of nervousness and expectation, and he kept saying, "It doesn't need to be too high, it just needs to be higher than the last time." ”

His voice trembled a little.

The last transition temperature was 119K, which is higher than 119K and naturally reaches or exceeds 120K.

Originally, the transition temperature of 120K did not have any special meaning, but after Amriken's news report on the investment of superconducting materials, the world focused on this transition temperature, and 120K became a special meaning, which means that it can be put into industrial use.

In fact, a transition temperature of more than 100K can actually be used in many fields.

Amriken has set a goal of 120k, which gives a special meaning to the 120k transition temperature, representing the goal that Amriken's large research team has been trying to achieve in three years.

Now they seem to be coming true soon!

Deng Huanshan was very excited to think about it, and so did others.

Everyone's eyes are fixed on the values on the measuring instrument.

150k……

140k……

135k……

The value is decreasing little by little.

When it was lowered to 132 k, the pointer slowly stopped, but the others did not shout out, and continued to watch for any changes.

One second, two seconds, three seconds......

When it came to the fifth second, someone finally couldn't help but shout, "132K!" ”

"Stopped! 132k！ ”

"More than 130k...... 132k! That's awesome! ”

Everyone involved in the test was excitedly discussing.

Everyone was excited.

Deng Huanshan is the same, "132k! Not only did we achieve our goal of preparing 120k materials, but we also went far beyond ......."

"Not bad!"

Wang Hao also took a deep breath and made another comment with a smile.

This data is similar to what he expected, and there is no surprise that 'exceeded expectations' last time, but it is indeed exciting to reach more than 130k.

Soon.

Another shiny material was also tested, and it was similar to Deng Huanshan's judgment, and the transition temperature was worse than that of the dim one.

The final result was 121k, just barely over 120k.

However, whether it is Deng Huanshan, Wang Hao, or the rest of the experimental group, they all agree that the shiny new material is much more valuable than the dull one.

Of course, it depends on the results of each test.

……

For the research results of the newly prepared materials, the superconducting materials experimental group made a confidential report.

The Science and Technology Division was soon informed.

The superconducting materials experimental group is a research team directly under the Science and Technology Department, and the confidential report of the research results was directly handed over to Zhao Enshun's desk.

Zhao Enshun was surprised to receive the news, and he also confirmed with his secretary, "Superconducting materials experimental group? West Sea's? Yan Shiqing? ”

The secretary nodded in acknowledgment.

"Didn't Yan Shiqing just take office? How did it come to fruition? Zhao Enshun was a little confused, but he still opened the file and looked at it carefully.

I was stunned at this sight.

Two new iron-based superconducting materials, one with a higher metal content with a transition temperature of 121K, and the other with a lower metal content with a transition temperature of 132K?

Just kidding, right?

Zhao Enshun rubbed his eyes vigorously, and read it carefully several times before confirming the content, he suddenly felt that his mind was blank, and it took a long time to turn around, and he quickly called a few responsible personnel.

Among them are Zhu Bin, deputy minister of the Science and Technology Department, Duan Xingguo, head of the Materials Department, and Xu Baogong, Zhou Minhua and others from the Science and Industry Bureau.

A group of people gathered.

Zhao Enshun said the newly obtained news with a shocked tone, and then the others were also shocked, "Minister Zhao, you're not joking, are you?" ”

"Yan Shiqing has just passed at most, right? Already bearing fruit? Moreover, 132k superconducting material? ”

"Could it be someone else? I know Deng Huanshan, he has long passed. ”

"It should have something to do with Wang Hao, right?"

"The reported document only said the results, but did not say the specific relevant personnel, but the results must be there, and they can't do this kind of oolong."

"This achievement is too big and too sudden......

A lot of people feel the same way.

Although the research direction of superconducting materials has been determined and a large amount of money is ready to be invested, it is still in the process of 'preparation'.

Even if there is already a preparation of funds, it is necessary to review and approve the appropriation step by step according to the content of each project, and the superconducting materials research center in Xihai is the first major project, and even the research center is still in the process of construction, and the director of the research center was only determined last month.

At this time, it was really unexpected, to suddenly say that there was such a significant achievement.

Some time ago, Amricon announced a major investment in the research of superconducting materials, and the largest experimental research center announced that it would strive to produce superconducting materials with a transition temperature of more than 120K and can be used for industry within three years.

However, the research over there has only just begun, and it is even said that it is still in the planning and has not really begun.

As a result, they have already been manufactured?

"I think we need to see this result with our own eyes before we can be sure." Zhou Minhua suggested, "Go and see how it was done, and talk to Professor Wang Hao and Academician Yan Shiqing about ......"

"Yes, yes!"

"Such a significant achievement, but it is amazing!"

"It's just that I don't know the specific situation at all in front of a report document, so I still have to look at it and discuss what to decide."

Zhao Enshun asked, "Don't wait for other news?" He was referring to the follow-up report.

When the research has significant results, the results will be reported first, and then the summary will be made, and the detailed research process will be written, including the report on the people involved in the research and their contributions.

Follow-up content will definitely need to wait for a while.

"Can't wait!"

Xu Baogong supported Zhou Minhua's idea, "Such a major achievement can be said to change the world, and there are too many fields that can be applied. ”

"If it's waiting for the documents to be submitted, when? This kind of research is complicated, what if something goes wrong in the middle? ”

The others also felt that it made sense, they were shocked to hear the news, and they also felt that they should see it with their own eyes.

Zhao Enshun listened to everyone's opinions and decided to immediately organize people to go to the experimental group in Xihai to have a look.

The impact of this achievement is too great.

As long as you have a certain amount of research on superconductivity, you can know what the concept of superconducting materials that can be used in industry above 120K.

That's a world-changing technology.

To take the simplest example - electricity storage technology,

Superconducting electromagnetic energy storage technology has been demonstrated by professional institutions around the world, and the technology is simply to use superconducting coils to store electrical energy.

The most famous of these are Ameriken Ebako Services and Beketel National, a new type of electrical energy storage technology researched by Ameriken for the Strategic Defence Project Agency and the Defence Nuclear Weapons Agency of the Ministry of National Defense.

The solution they came up with was to feed electricity into a superconducting coil the size of a football field when electricity was not used in normal times.

The coil is made of niobium-titanium alloy and soaked in a deep pit filled with liquid helium.

When an electric current circulates through a superconducting coil, a magnetic field is formed around the coil, which stores electrical energy as magnetic energy.

The superconducting material used in this scheme is niobium-titanium alloy, and the superconducting transition temperature of niobium-titanium alloy is only about 8K to 10K.

Such a low temperature must be in the environment of liquid helium, which is undoubtedly very expensive.

If it is the use of new materials as superconducting materials, then it is enough to soak the superconducting coil in the environment of liquid nitrogen, which is relatively cheap, and the cost and maintenance of the superconducting storage device manufactured will be extremely reduced, and there must be the possibility of implementation.

The 21st century is the world of energy, and the storage of a large amount of electricity is very difficult.

Most of the electrical energy is used when it is manufactured, and the part that is not used is wasted, which leads to the fact that the electrical energy function is sufficient in some seasons, and the electric energy supply is insufficient in some seasons, and it will be affected by other facilities.

If there is a large-scale device to store electrical energy, the excess power can be stored, and the problem will be solved perfectly.

……

Academy of Sciences, Institute of Mathematics.

Recently, Yan Shiqing has often visited the Institute of Mathematics, hoping to persuade more experts in algebra and geometry to work in Xihai.

His work has also been remarkable, convincing scholars in five fields of algebraic geometry.

Yan Shiqingzheng said to Meng Guosheng, "Guosheng, if you go to work in the West Sea, you can not only participate in the most cutting-edge research, but also make more money!" ”

"Think about it, what can you do in math? With such a small salary a year, we do research and say that we are scientists, but the institute really can't keep people. ”

"When I go over there and participate in big projects, the subsidies are a lot, and it's not a job change, and I'm still hanging in the Institute of Mathematics, I can apply to my superiors, it's a temporary transfer of work."

At the age of forty-five, Meng Guosheng is a researcher at the Institute of Mathematics and one of the top figures in the field of algebra and geometry in the Institute of Mathematics.

Because of this, Yan Shiqing focused on 'tackling key problems' Meng Guosheng.

Meng Guosheng was already very moved.

If he was a teenager younger, he would go to Xihai without hesitation, but now that he has a family and no job in Feicheng, it is definitely inconvenient to go to Xihai to work.

But considering the salary, he is still very excited.

As an ordinary researcher in the Institute of Mathematics, he will get more than 100,000 yuan a year, and his doctoral classmates have gone to work in enterprises, and some of them have an annual salary of one million.

That's a huge difference.

"If you go to the West Sea, how much more can you get?" Meng Guosheng is concerned about this issue.

Yan Shiqing immediately grinned, he knew that Meng Guosheng was moved, so he continued, "At the minimum, take an extra 50,000 or 100,000, there is no problem, not to mention doubling the salary, it will definitely rise significantly." ”

In fact, he doesn't know exactly how much more money he can get, but there must be subsidies for big projects.

Meng Guosheng hesitated: "I'll go back and discuss it with my family." ”

Yan Shiqing persuaded Meng Guosheng, he was still happy in his heart, he went by himself, he always felt alone, and he could go with a few algebraic geometry scholars, and he could have more confidence.

When 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 been to the West Sea?" Wu Hui on the other end of the phone was a little anxious.

"No?"

"Why haven't you gone yet?"

"Right away." Yan Shiqing frowned and said, "I'll look at the time, and it will be over next week." By next Monday, it's only the 15th. ”

He shook his head as he spoke.

Originally, it was planned that the end of the month would pass, but Wu Hui kept urging and urging, so he decided to advance a little earlier.

Wu Hui's reaction was a little unexpected, he seemed to sigh, and then said, "I think, you can carefully consider whether you want to go to the West Sea." ”

"Why?"

"This ......"

Wu Hui didn't say it directly, but said, "Anyway, you're thinking about it, you're 63 years old, and it's good to wait for retirement at the Academy of Sciences." ”

“…… What do you mean by that?"

"Good for you!"

"Good for me? Don't let me go? Such a significant study? ”

Yan Shiqing said that his tone was not good.

I had been urging him to go over, but now it has become a suggestion that he put down his job and continue to stay in the Academy of Sciences for retirement?

After Yan Shiqing put down the phone, he felt very angry when he thought about it, he thought about it carefully, and suddenly had a sense of urgency, "Go back and report and submit the names of Meng Guosheng and several people!" ”

"It seems that we can't wait for next week, Thursday and Friday will pass!"

He pondered, "Someone must have taken a fancy to the position of director of the research center, otherwise Wu Hui wouldn't have said that!" ”
