Chapter 207 A new era of superconducting is coming!

The superconducting temperatures tested by the previous few superconducting materials and laboratory tests are almost the same as those predicted by the software.

This proves that Xu You's software simulation has very high accuracy.

If nothing unexpected happens, this time the 200K superconducting material should not have too many prediction errors.

Xu You and Qiao Sen still began to measure the material resistance as before.

This time, they didn't even use liquid nitrogen, so they used dry ice as a coolant.

This is not simply to conform to the concept of "dry ice superconductor".

But this is the case, it is easier to control the temperature above 195K.

Of course, Xu You and Qiao Sen both know that the predicted value of the critical temperature of the superconducting this time may be larger than the actual situation.

Because Xu You's simulation model does not have so many data on substances with very high critical temperatures in superconducting.

In the previous superconductors with critical temperatures of 160K, 170K, 180K, etc., the predicted value and actual value both showed slightly larger errors.

Therefore, if the temperature after dry ice is not sufficient this time, you should continue to change to liquid nitrogen for refrigeration.

As the temperature dropped little by little, everyone focused on the screen.

They all know that when the resistance curve of a substance drops sharply.

The matter enters a superconducting state.

When the temperature is about to approach 200K.

Xu You controlled the temperature reduction rate relatively slowly to better determine the critical superconducting temperature of the substance.

If the temperature drops too fast, the critical temperature may be missed in a moment.

"Um?"

At this time, Xu You, who was cooling down, suddenly discovered it.

When the system temperature drops to 202K.

The resistance of matter suddenly decreased sharply.

Others in the laboratory also noticed such a situation.

"202K!" said a professor.

He looked very excited, but on such occasions, he was also trying to restrain his voice.

No one can celebrate the result in advance before the experiment is over.

Xu You and Qiao Sen also remained serious and continued to complete the resistance measurement experiment.

But they were also very excited because such a superconducting critical temperature was even 2K higher than the predicted value.

This means that this new type of substance can be completely cooled by dry ice to reach the superconducting state.

Finally, after repeated careful measurements.

Xu You determined that the accurate superconducting critical temperature of this substance is at 202.26K.

After the measurement experiment of superconducting critical temperature, everyone can finally celebrate it.

"202.26K! It's even more than 2K higher than the predicted value. In this case, using dry ice as coolant is definitely enough. Superconductors are really going to usher in a new era!"

"Xu You's theory and this algorithm... are really amazing! This is no longer just a Nobel Prize-level achievement, it is a completely cross-age achievement!"

"These achievements will definitely make great contributions to the entire human race in the future! However, the core technology must be in our own hands, so that they can also taste the feeling of being bored!"

After some discussion, Xing Shuping said:

"This is indeed a very celebratory achievement. It can be said that it has been the biggest breakthrough since the project was established. However, everyone should still remember that there is still a long way to go, and the application value of this material cannot be determined yet.

. ""

Although the material has been synthesized, its superconducting properties and very high superconducting critical temperature have been verified.

However, future material forming technology, including the cost of material synthesis, is also a big problem.

According to the huge cost of synthesising this material at present, it is definitely difficult to apply to a large number of industries.

"There are still problems with my simulation system."

After being excited, Xu You also began to reflect on his simulation system.

As the critical temperature of a substance's superconducting temperature becomes higher and higher, the gap between the predicted value and the actual measured value will become larger and larger.

Although it seems that this is not a big problem at the moment.

But Xu You vaguely feels that this will have a great impact on finding superconductors with higher critical temperatures in superconductors, or even room temperature superconductors.

Because the large number of superconductor samples Xu You referenced before were superconductors with a critical temperature of less than 138K.

This is likely to indicate, but when the critical temperature of the superconducting substance is high enough, some new changes will occur in certain properties.

This may even be part of Xu You's high-temperature superconducting mechanism that has not been explained.

Xu You also needs to further summarize the various properties of these newly discovered superconductors and find some new rules from them.

In the days that followed, Xu You further measured the complete antimagnetic properties of these substances and the properties of flux quantization.

These are three essential properties that superconductors are essential.

The results after measurement are very satisfactory, and these substances satisfy these three basic properties.

Although these results are certainly not publicly published due to the confidentiality of the project.

However, it is of great significance to a more comprehensive understanding of the characteristics of these substances.

Now, whether scientific research results can be published publicly is nothing to Xu You.

Xu You just wants to discover more truths as much as possible and satisfy his heart.

The material experts of the project continued to start research on the preparation and molding of this material.

On the one hand, we must reduce the preparation cost as much as possible and strive to achieve popularization in the future.

On the other hand, it is necessary to develop material forming technology that can be made into wire strips, etc., which is more conducive to application of molding materials.

So far, Xu You has no better new direction for these technologies.

After all, in materials science, Xu You still cannot compare with those top Chinese materials experts.

...

On this day, Xu You was still doing experiments on high-temperature superconducting in a laboratory of condensed matter physics as usual.

Regarding the theory of high-temperature superconducting mechanism, Xu You feels that further supplements and revisions are needed.

At this time, someone opened the laboratory door.

Xu You subconsciously looked over and found that it was Qiao Sen.

And behind Josen.

There were also two people who were more familiar to Xu You.

It turned out to be Han Shubin and Liu Jiao.

"Academician Han, Teacher Liu!"

Xu You never thought that Han Shubin would suddenly come.

When Xu You saw them, he subconsciously greeted them.

Han Shubin smiled and said, "Xu You, suddenly visiting will not disturb you from doing the experiment, right?"

"No, it's not a very urgent experiment, you can do it anytime."

These experiments are just a few sets of experiments added by Xu You himself, hoping to further improve the previous high-temperature superconducting mechanism.
