Scholar’s Advanced Technological System

In February, snow fell in Jinling, and it was the New Year.

These days, Lu Zhou has almost lived in the laboratory.

Although I bought a house, I didn't go back and live there a few times. It's a pity.

Fortunately, a few days before the New Year, the research at hand was finally completed, and this made him breathe a sigh of relief.

In fact, these tasks do not have to be completed before the new year.

However, the achievement of this result at this time can still add some chips to his trip to Germany.

In any case, in order to carry out follow-up research, a star simulator is necessary.

An email was politely edited and sent to Professor Kreiber, who was far away in Germany. Lu Zhou changed his coat and left the institute.

After getting out of the institute, he took a breath of fresh air. Before going home, he made a round trip to the construction site of the STAR Imaging Institute.

The cold did not freeze the enthusiasm of the workers at all, just as when the project was just opened, at this moment, the site was in full swing.

Almost every time I pass here, Lu Zhou can feel it is different from the last time.

With the support of ten times the human and material resources, the progress of the project is in units of days and is advancing at a speed that is visible to the naked eye.

It happened to be on-site inspection, noticed the land boat coming down from the car, and Dai Dai stepped forward, and greeted him with a smile.

"What wind brought you here?"

Lu Zhou: "I'm preparing to go home. Just passing here, I came here to make a circle. It's going to be a New Year, and you are working hard."

Captain Dai said indifferently: "It's okay, what a painstaking effort?"

The project is not accepted, and no oath of assembly is sworn.

This year's New Year's Eve, from the beginning, they had no plans to eat outside the construction site.

A few words of conversation with Lu Zhouhan, looked at the research institute not far away, Dai Dai squinted his eyes, and said something amused: "If you say that our country uses controlled nuclear fusion How much energy can I save on energy each year? "

"I didn't get the Nobel Prize in Economics. I'm afraid I can't give you an accurate figure."

Just a joke, Lu Zhou paused for a moment and continued, "But one thing is certain, when the day really comes, the electrical industry in our country will usher in a leap forward."

Although Lu Zhou did not study economics, he intuitively told him that the value in it was not measurable with money.

Dai Dai: "Leap? Like when you changed?"

Lu Zhou said in a joke tone: "It's hard to say, maybe it's the Industrial Revolution."

The industrial revolution ...

This sounds really a distant word.

Even in the history of human civilization, it has happened only three times.

Looking at the building not far away, the head of Dai Dai couldn't help but look forward to it ...

...

Jinling's snow came fast and walked fast, and stopped shortly after.

But for most cities in northern Europe, it was still a silver-clad scene.

At the corner of the Baltic Gulf, in the quiet outskirts of Greifswald, Kreiber, sitting in the Spiral Stone 7-X laboratory, is checking his work email.

Just when he had finished processing all the unread mails, suddenly another unread mail flew into his mailbox.

He opened the mail, and when he saw the sender, Kreber gave a slight hesitation.

Luzhou?

After seeing the name, Kreiber's expression was slightly adjusted, and he continued to look down the body of the email.

[Dear Professor Kreiber, 】

[In a few days, it will be the Chinese New Year. In this auspicious moment, I sincerely wish you good health and good luck. 】

[In addition, I have good news here, I believe you will be interested ...]

After reading this, Professor Kreiber raised his eyebrows, and an interesting look immediately appeared on his face.

If others said that, he might not believe it.

But this is what Lu Zhou said. Even if he didn't know what he was going to say, he couldn't help but expect something.

[... In order to improve the problem of insufficient constraint magnetic field strength, we have tried many schemes. In the end, we succeeded on a carbon-based superconducting material. 】

[You know, of the many engineering problems that restrict the increase in electromagnetic field strength, the most critical one is that it is difficult to continue to expand the coil size on the premise that the copper oxide conductor is at the superconducting transition temperature. After all, no matter the copper oxide material or the channel through which it transports liquid helium, the volume occupied by the entire superconducting magnet project is not small. 】

[In order to solve this problem, we have made many attempts. The most important consideration is to increase the transition temperature of the superconducting material as much as possible and make it as close to room temperature as possible to reduce the occupation of the cooling device in the entire project. volume. 】

[In fact, because of this experimental idea, we have indeed achieved a lot of results. But just then, we unexpectedly discovered that in order to solve this problem, we don't necessarily have to start with the transition temperature. 】

[Taking copper oxide as an example, if one wants to maintain the copper oxide conductor at the superconducting transition temperature, one of the most difficult problems to overcome is the poor thermal conductivity of copper oxide. It is really not friendly enough. 】

[And as a superconducting material, graphene has excellent performance in both horizontal and vertical heat dissipation. In theory, the thermal conductivity can even reach 5300W / m · k. 】

[You're an engineer, you should know exactly what this means. 】

Originally, he was reading this letter very seriously, but when he saw it, Kreber smiled and shook his head.

He certainly knows what this means, even if the thermal conductivity of the SG-1 material is not as exaggerated as 5300W / m · k, more than a thousand thermal conductivity is enough to explode copper oxide with poor thermal conductivity.

You know, even pure copper ~ www.wuxiaspot.com ~ The thermal conductivity is only 401W / m · k.

what does this mean?

This means that in the engineering sense, if the difficulty of keeping copper oxide at the superconducting transition temperature is 10, then the engineering difficulty of keeping the graphene conductor at the superconducting transition temperature is only 1 or even less.

In fact, in some cable materials or electronic devices, graphene itself is used as a higher-grade heat sink than graphite.

However, the problem is that the superconducting performance of the SG-1 material is reflected in the overlapping angle of the two-dimensional material. How do you plan to process the SG-1 material into a wire?

This is not as simple as baking a millet.

At least Kreiber himself couldn't figure out how to process the stuff that appeared in the laboratory into wires.

Not to mention, that expensive price ...

However, at this moment, he was suddenly holding back while reading the mail.

I saw, at the end of that email, Lu Zhou wrote--

[... in fact, we have successfully found a suitable method. Even though it may not seem so reliable, we have successfully obtained a length of one and a half meters of wire. 】

Sitting up sharply, Kreiber almost didn't fall out of the chair.

Noting the situation here, his assistant quickly asked, "What's wrong, professor?"

"It's nothing," holding the arm of the chair firmly, Kreber sorted his lower collar a little bit hesitantly, then looked at his assistant. "Help me book a ticket. I'm going to Hualing Jinling."

The assistant froze slightly and turned the pen in his hand.

"... what's the number?"

Without any hesitation, Kleiber said earnestly.

"Now, or soon!"
