What exactly are superconductors used for?

It can be said that wherever electricity is used, there is a place for superconductors.

Superconducting magnetic levitation, superconducting power transmission, superconducting transformers, superconducting generators, superconducting motors, superconducting current limiters, and energy storage systems enable efficient power grids and motors.

Superconducting magnets made of superconducting coils have the advantages of small size, high magnetic field, good uniformity and low energy consumption, and are the core of key technologies such as high-resolution nuclear magnetic resonance imaging, basic scientific research, and artificial controllable nuclear fusion.

In addition, the preparation of superconducting qubits based on superconducting quantum interferometers is the most important quantum unit in quantum computing in the future, and high-performance computers based on the principles of quantum mechanics will set off a new information revolution......

Because of the broad application prospects of superconductors, the study of room temperature superconductivity has been an important frontier in basic physics research since the discovery of the first superconductor "metallic mercury" in 1911.

Scientists are optimistic about whether room temperature superconductivity can be realized.

Because at the end of the day, superconductivity is about finding the limits of various materials, such as the difference between steel and pig iron due to the difference in carbon content in iron.

But it is very difficult to find this material, it is very difficult, it is very difficult, it is difficult to the probability of 1 in 100 million.

It's harder than buying a welfare lottery ticket and winning the first prize three times in a row.

All physicists know that it is unlikely that they will be able to see the realization of room-temperature superconducting materials in their lifetime.

However......

When the news broke out half an hour after the Chinese People's Network broke out, the world was shocked and incredulous.

Countless scientists have called the Chinese Academy of Sciences and relevant parties for verification.

An hour later, the Chinese Academy of Sciences issued a notice affirming the news spread on the Internet and saying that it would hold a press conference at 9 o'clock tomorrow morning in the Kyoto Hall of the Great Hall of the People to announce major academic achievements.

Regarding the announcement issued by the Chinese Academy of Sciences, except for the person concerned, all scientists in the world engaged in superconductor research firmly do not believe it.

This must be an oolong.

This must be a gimmick by the Chinese government.

This must be......

Superconductivity at room temperature, this is absolutely impossible!

Not only do foreign scientists not believe it, but 99% of Chinese scientists and netizens do not believe it.

There is a lot of talk on the Internet.

"Although I know it's impossible, I choose hope!"

"Be confident, it's absolutely impossible!"

"I bet with the dog's head upstairs that normal temperature superconductivity will not be possible for 100 years. ”

"With China's technological accumulation in the field of basic physics, if you want to study superconductivity at room temperature and pressure at this stage, I'm afraid you haven't woken up!"

“……”

Chen Xu, who was at the headquarters of the Sioux City Group, was also a little surprised after getting the news.

There are still some problems in the preparation process of cage carbon ion superconductor (CWC-1001) that need to be solved urgently, and it will take at least half a year to solve them according to the research progress.

Can't wait to launch it now, is there something wrong with the country?

Chen Xu immediately called Wei Botao.

As soon as the phone was connected, Wei Botao asked happily, "Are you in Kyoto?"

"No, I'm still in Sioux City. Isn't there still a few problems that haven't been solved, and they're going to be announced so soon?"

"Those questions don't affect the presentation. Wei Botao said a word and said: "And the leaders above believe that it is necessary to show their muscles to some Western countries, so they will not wait." ”

When Chen Xu heard this, he immediately remembered that China and the United States have recently clashed with the United States on some issues in Africa and Latin America, and the United States has also taken this opportunity to constantly instigate China's neighboring countries to encounter porcelain provocations.

Countless netizens are indignant about this, and many believe that there will be a war between China and the United States, and it will not be too long.

On this occasion, China urgently needs some exciting good news to cheer up!

Thinking of this, Chen Xu thought of Wei Botao's words again, and as soon as he answered the phone, he asked if he had arrived in Kyoto, indicating that he thought he should be in Kyoto at the moment.

It seems that Kyoto sent someone to find him, as for the purpose, first, it should be for him to attend the press conference to be held in Beijing tomorrow;

Second, although superconductors are enough to sensational the world, since they want to show their muscles, they should want to take this opportunity to break free from the chains imposed on China by Western alliances of interests, such as the Wassenaar arrangement.

Superconductors alone will not be enough to get the coalition countries to abandon restrictions on China.

So if nothing else, in addition to announcing superconductors, this press conference will also announce the core technology of lithography machines mastered by China!

Just as Chen Xu was thinking about these things, Su Yi came over after answering a phone call, and stood next to him without speaking.

As soon as Chen Xu saw her expression, he knew that Kyoto really had someone to come.

"They're coming, and we'll talk when the evening comes. Chen Xu said into the phone, put away the phone and said, "Let's go." ”

……

The person who came was a heavyweight leader in the Ministry of Science and Technology, named Ren Zizhen, very young, only 40 years old, speaking an authentic Beijing accent, and his face looked very subsequent.

After the two sides exchanged pleasantries, Ren Zizhen explained his intentions.

As Chen Xu expected, the above hopes that he can sing a big drama with the country,

This should be divided, Chen Xu naturally has no opinion, saying that he will provide some self-developed cutting-edge equipment samples and disclose the raw material production workshop.

Seeing that Chen Xu nodded in agreement, Ren Zizhen smiled again: "In addition, the chief hopes that you can attend the press conference and personally show the scientific research results to the media." ”

"Ah...... Me?" Hearing Ren Zizhen's words, Chen Xu was a little surprised.

Is this an attempt to establish him as a science icon?

It's possible.

But the problem is that he doesn't like flowers and applause everywhere, he likes to study science quietly, make some bizarre inventions, or quietly lie on the roof and watch the universe and stars.

Therefore, except for academic seminars, he declined all media interviews, including Xinghai Science and Technology News, a subsidiary of his group, and there was basically no gossip about him on the Internet, because he didn't like to be in the limelight in his bones, and he didn't like the public to focus too much attention on him.

However, the face of the GWY boss cannot but be sold.

Seeing Ren Zizhen looking at himself with a smile, Chen Xu finally said helplessly: "Okay!"

The face of the big guy above can't help but sell.

Hearing Chen Xu's words, Ren Zizhen showed a happy smile on his face, stood up and held his hand and said, "Thank you, Professor Chen." ”

"You're welcome~"

Kyoto, Nishigu-gu Nakkai.

In the office, two majestic men were talking about Xinghai Technology.

One of the men with a Chinese character face said: "I talked to him last time I went to Zhongxing for research, although he is young, he has a calm personality and no problems in terms of thinking, which is very commendable!"

Going back and looking at it, there are certain areas that might as well be open to their companies to a limited extent. ”

Another round-faced man nodded and said with a smile: "Yes, this young man is indeed very powerful, especially in the software field, he is simply a genius, which makes people have to admire!"

But...... I think we still need to observe and observe more, and wait until the mind is stable. ”

"Okay! I'm just a suggestion, you should do your own research. ”

"Hmm!"

……

Kyoto Kayama Park.

Normal University has an industry at the foot of Xiangshan Park, which is an annex composed of two small western-style buildings, which was allocated to the Department of Fine Arts for students to go out to sketch.

Going out is Xiangshan, the trees are verdant, the maple leaves are like fire, and the rippling Xiangshan Lake, the scenery is exceptionally beautiful, and it is a very pleasant thing to sketch here.

Of course, if you want to sketch here, you have to pay accommodation fees, and you must be a student with a master's degree or above to be eligible to apply, and you may not be able to pass, after all, there are only two buildings in the annex, and it can accommodate a dozen students at most.

Shen Yiqiu lives here at the moment.

She had already graduated with a master's degree, because she didn't want to leave campus for a while, and then she continued to study for a doctorate.

There is another reason, Chen Xu is also studying for a doctorate at Qingdao University.

At three o'clock in the afternoon, Shen Yiqiu, who had a ball on his head, and two other women and a man, four of them lined up, sitting by the quiet lake, depicting on the drawing board, with an oil painting of the sun setting in the west.

The big-faced girl who was wearing a pair of flat glasses next to her to cover her squinting eyes asked, "Yiqiu, it seems that your boyfriend hasn't been here for a long time, what has he been busy with lately?"

"All said, he's not my boyfriend. ”

"Okay, okay, it's not your boyfriend, it's your confidant. ”

"Hmm!"

"What about the others?"

"He's busy experimenting every day. ”

The tall and thin boy sitting on the far right jokingly said, "Yiqiu, or we can make do with it." ”

Shen Yiqiu smiled and didn't speak.

The girl with a big cake face said: "Xiaowei, you ask your father to work hard and strive to become a department-level cadre, maybe there will be a chance." ”

The boy named Xiaowei said helplessly: "My dad is in his 50s, and he has just been promoted to the deputy department, it would be good to be able to get a regular position before retirement, but it is impossible to be at the department and bureau level......"
