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.
