"My personal suggestion is not to rush to promote the 202K high-temperature superconducting cable technology..."

The reason why Xu You suggested this was not because he was worried that the technology was not mature enough.

Instead, there are some other ideas.

In the field of superconductivity, Xu You believes that it is far from the end.

In the proposal, Xu You clarified his theoretical basis for making these proposals.

At present, various researches on superconductivity are progressing in an orderly manner.

Within a few years, it is very hopeful that another major breakthrough will be achieved in the field of superconductivity.

Although the construction of high-temperature superconducting cables has a great effect on saving power transmission losses, the construction of cables itself requires a lot of cost.

This part of the cost is difficult to recover in the short term, and it may even take decades to recover the cost.

If a better superconducting material is discovered within a few years, it will need to be rebuilt.

Xu You's proposal was well-founded and was unanimously agreed by the insiders.

After all, in the field of superconductivity, there is no one in the world who is more professional and authoritative than Xu You.

...

In a recent report, the room-temperature superconducting project studied by Lin Shi and others also made new progress.

After many experiments, it has been proved that for many high-temperature superconductors, their superconducting critical temperatures have increased to varying degrees under the condition of ultra-high pressure.

These superconductors can be called "room temperature superconductors" in a broad sense.

"Mr. Xu, we have discovered several superconducting materials. In the range of 200GPa to 500GPa, their superconducting critical temperature exceeds 300K. As long as they meet extremely high pressure, they can indeed achieve superconductivity at room temperature."

The 300K in the thermodynamic temperature is about 27 degrees Celsius of the Celsius temperature, which can be said to be the real normal temperature.

Although before this, many people believed that high-voltage room-temperature superconductors had only theoretical significance and no practical application value.

But Xu You now feels that this is likely to provide a new idea for the realization of room temperature superconductivity.

"Very well, the next thing we have to do is to study the core mechanism of these superconducting materials, which can increase the superconducting critical temperature under high pressure. During this period, I will do more experiments with you."

Now that Xu You has given a suggestion to delay the popularization of the 202K high-temperature superconducting cable project.

Naturally, Xu You should shoulder the responsibility and put the progress of the project on the agenda.

If there is nothing particularly important, Xu You will follow the next experiment all the way.

In the next experiment, Xu You participated in the experiment as scheduled.

"Lin Shi's current level of experimental operation is really proficient."

Seeing Lin Shi's skillful operation during the experiment, Xu You couldn't help being amazed.

The synthesis and measurement of high-pressure materials has always been a great challenge for various laboratories.

In particular, it is very difficult to realize ultra-high pressure technology by using diamond anvils.

Other top scientific research teams in the world also encountered many problems when doing similar experiments.

It is common for diamonds to be broken due to operational errors.

Compared with these problems of wasting resources, one of the more frightening things is that the experiment has not been successful due to the huge cost.

If it is due to some force majeure factors, there is nothing to regret.

If it is due to problems such as poor technology and operational errors, it is indeed unreasonable.

During the break of the experiment at noon, Xu You deliberately found Lin Shi.

"What's the matter, Teacher Xu?"

"It's nothing, I just want to praise you. The experiment is really well done. Especially the use of diamonds on the anvil has at least reached the top level in China."

Lin Shi was also flattered by Xu You's face-to-face praise.

"Did I hear you right? I was praised by Teacher Xu? Wait a minute... Teacher, don't you have anything to criticize me for?"

"In your heart, am I the one who likes to criticize students so much?" Xu You smiled wryly.

"No, it's just that I'm not used to being praised by you. I feel that I'm not that good yet."

"Don't be so unconfident. When it's time to praise, you should praise it. If it weren't for your high operational accuracy, the progress of the project would not be so fast."

"Hehe, the main reason is that I really feel sorry for those diamonds. If I break a pair, I will lose 20,000 yuan. I must be more careful."

Xu You knows in his heart that Lin Shi's talent is very outstanding, and he is also a top existence in Jijing University where there are many talents.

But compared to real geniuses like Lou Song and Nie Jie, Lin Shi is still inferior.

What impressed Xu You the most was not Lin Shi's talent, but Lin Shi's hard work.

As early as when Xu You and Lin Shi met for the first time, they were studying competitions together.

Lin Shi didn't feel backed down by Xu You's excellent grades, but faced up to the difficulties and took the initiative to sit in the seat next to Xu You.

Not for anything else, just want to compete with the best students.

Xu You still remembers that when Lin Shi first participated in the experimental training, the experimental operation methods were also very jerky.

Unexpectedly, in the past few years, Lin Shi has made great progress in the experimental operation.

If he persists like this, Lin Shi is very likely to become a physicist recorded in history.

After a period of intense experimentation.

The project team summarized the unified laws of these room temperature superconductors under ultrahigh pressure.

"For these superconductors, under ultra-high pressures ranging from 200GPa to 500GPa, the atomic spacing inside the material changes, and at the same time promotes a phase transition in its structure. This allows these materials to obtain some special electronic structures and states of matter." Lin Shi Said.

Such changes do not need to be at very low temperatures.

As long as the pressure is high enough, these changes can also be achieved at room temperature.

After summing up these laws, Xu You came up with a new idea.

"Is it possible to cause similar changes in materials without the use of external conditions of ultra-high pressure? Or, is it possible to create a material that has similar special properties under normal pressure? ?”

Xu You wondered if other scientists in the world had proposed such an idea.

But at least among the various documents and materials that Xu You has read, there is no scientist who has put forward a similar hypothesis.

After deciding on this direction, Xu You thought about a specific solution.

When studying high-temperature superconducting materials, Xu You once used a set of programs written by himself to predict the superconducting properties of materials.

These predictions are extremely accurate at lower temperatures, and even the superconducting critical temperature does not have much error.

But when it is close to 210K, the error begins to increase significantly.
