Great Country Academician

Kelvin didn't care about the behavior of others.

Those who came here today, in addition to wanting to see the performance and data of this high-temperature copper-carbon-silver composite superconducting material, are actually potential competitors.

Compared with chatting with this colleague, he hopes to have the opportunity to chat with that Professor Xu after the press conference.

Regardless of whether the high-temperature copper-carbon-silver composite superconducting material developed by Professor Xu can be commercially produced, he wants to get a chance to cooperate.

If this high-temperature superconducting material cannot be industrially produced and commercially used at present, he can chat with Professor Xu on behalf of Nexans to see if they can reach a cooperation and let them study the industrial production method of this material .

If this high-temperature superconducting material is already ready for industrial production and commercial use, then they will have a chance to cooperate.

Normal pressure state, 152K superconducting temperature, the performance of this material, as long as the critical magnetic field and critical current density are not too bad, it is destined to crush all the current superconducting materials in the world.

Nexans is a very large company, one of the top 500 companies in the world, and one of the top ten integrated wiring brands in the world. Including cable manufacturing and engineering in many countries around the world.

Many of its products, such as winding wires, submarine cables, data cables, and power cables, are ranked first or second in the world.

But if you don't keep up with the pace in the field of superconductivity, you will soon miss this era and become history.

Superconducting materials are a revolution, and with its development, those companies that lag behind will eventually be dusted.

In the past two hundred years, several industrial revolutions have created several different powerful countries.

For the first time in the country on which the sun never sets, the development of steam engines and related technologies made the empire on which the sun never sets almost ruled the world;

The second time in Europe and the United States, the development of electric power, internal combustion engines and chemical industries made machine production more efficient and large-scale, which further promoted the industrialization process and made Europe and the United States stand on the top of the world;

The third time occurred from the middle of the 20th century to the present. The development of computer, Internet and communication technologies led by the United States has made machine production more intelligent and automated, thus promoting the process of digitization and informatization.

From a historical point of view, each industrial revolution has lasted about a hundred years, and each time there will be one or several scientists who lead the times in the field of science.

Today, the third industrial revolution has been developing for more than 80 years, and what is visible to the naked eye has come to an end.

The gradual weakening of the United States and the gradual rise of Huaguo seem to mean the end of the third industrial revolution and the beginning of the fourth industrial revolution.

Coupled with the appearance of that Professor Xu, in today's scientific world, it seems like those legendary scientists in history. In the dark, Kelvin Noah seems to have heard the wave of the fourth industrial revolution. .

At ten o'clock in the morning, the press conference on high-temperature copper-carbon-silver composite superconducting materials officially began.

Xu Chuan stepped onto the podium steadily, and behind him, a huge silver-white projection screen opened.

[152K, high temperature copper-carbon-silver composite superconducting material]

A line of bilingual titles in Chinese and English appeared on the screen, and a silver-gray film rotated in the center of the screen, representing today's theme.

With his coming to the stage, the originally slightly noisy venue became quiet in an instant, leaving only the sound of the camera clicking.

Standing in front of the podium, Xu Chuan looked at the crowd and said, "First of all, I welcome you to come here for today's press conference."

"The theme of today's report is just like the screen behind me. It is the press conference of the latest achievement of Chuanhai Materials Research Institute's high-temperature copper-carbon-silver composite superconducting material."

While speaking, Xu Chuan opened the PPT copy prepared in advance by the research institute.

"Superconducting materials and superconducting technology are one of the greatest discoveries of the 20th century. They have excellent properties and broad application prospects."

"Since 1911, the physicist Onnes found that when the temperature dropped to 4.15K, the resistance of mercury suddenly dropped to zero. In the past few decades, superconducting materials have become a hot field of physics research and material research. .”

"However, achieving superconductivity is difficult and requires extremely low temperatures, thus limiting its widespread use in practical applications"

On the podium, Xu Chuan talked eloquently, from the history of superconducting materials to the present, to its importance, and then extended to the development of superconducting materials today and "high-temperature copper-carbon-silver composite superconducting materials".

"At normal pressure, the Tc critical temperature of 152K is Chuanhai Materials Research Institute, and it is also the first answer sheet I handed over on this road."

"I believe that everyone here has already obtained some of the relevant attributes of this material from the invitation letter or other means before coming here, so I will not hold your appetite."

While speaking, Xu Chuan pressed the remote control pen in his hand.

The screen of the projection screen behind him jumped, and a form appeared on the screen.

【Critical temperature (Tc): 152.7K】

[Critical magnetic field (Hc): At 152K, Hc is 20.142T, and at 77K, Hc is 23.268T. 】

[Critical current (Ic): up to 5500A/mm2 at 20T. 】

[Critical current density (Jc):]

【Thermal conductivity: 572.3W/m·k】

【.】

The test data item by item was displayed on the curtain. Under the stage, the manufacturer representatives who saw this form gasped involuntarily.

As a representative of the superconducting material company who came to participate in today's report meeting, everyone is very clear about the meaning of the data on this form.

It is no exaggeration to say that this is a new material that subverts the current field of high-temperature superconductivity.

Its performance is better than that of copper oxide-based high-temperature superconducting materials. Not only the critical temperature, but also the parameters of superconducting indicators such as critical magnetic field and critical current/current density are almost crushed.

If you want to say a disadvantage, it is somewhat insufficient in some aspects of conventional physical properties.

Although the copper oxide-based high-temperature superconducting material is also in the ceramic state, some of its composite materials exceed this material in terms of toughness, brittleness, stiffness, and fatigue strength.

But if compared with the excellent performance of this material in terms of super performance, it is not unacceptable that its physical properties have some defects.

At least, there is no problem at all in the use of equipment such as large-scale strong particle colliders, medical equipment, and maglev trains with a stable environment or using plates as superconducting instruments.

In addition, although this high-temperature copper-carbon-silver composite superconducting material is highly brittle, it is not a big problem to use the complete diamagnetism of the superconducting material to manufacture some precision instruments, such as frictionless gyroscopes, bearings and other equipment.

After all, as long as it does not cause too much vibration, accessories made of highly brittle materials are not so easy to break under normal circumstances.

Just like jade, unless you hold it and throw it on the ground or something, it will not break if you simply play with it or wear it in your hand.

Therefore, if a stable workplace can be provided for this material, it is not impossible to use it to manufacture some high-precision equipment for use.

Of course, if shaping the shape is a trouble spot. But this is basically nothing for major manufacturers. No matter how strange the shape is, as long as someone needs it, as long as there is money to make, they will try their best to make it.

Xu Chuan didn't waste too much time at the press conference, and Xu Chuan started to finish in about half an hour.

"This is the end of today's press conference."

"Next, if you have any questions about the 'high-temperature copper-carbon-silver composite superconducting material' developed by our Chuanhai Materials Research Institute, you can ask them now."

After the words fell, someone in the audience stood up with their hands raised.

Xu Chuan signaled the staff to hand over the microphone.

The questioner was a middle-aged man in a suit and leather shoes. He said, "Hello, Professor Xu, I am the representative of the Furukawa SuperPower Research Institute. I would like to ask whether this high-temperature copper-carbon-silver superconducting material has been Is it ready for mass production?"

When this question was raised, all the manufacturer representatives in the venue raised their ears.

Undoubtedly, this is the most critical question for everyone present.

On the podium, Xu Chuan said: "Currently, high-temperature copper-carbon-silver composite superconducting materials have not entered mass production, and I am looking for methods and cooperation companies for mass production."

As soon as the words fell, the arms in the venue quickly raised up.

Xu Chuan randomly picked one, and the other party quickly stood up and took the microphone from the staff: "Professor Xu, regarding this high-temperature superconducting material, will you apply for a patent and then sell the patent authorization like the previous artificial SEI film?" ?”

Xu Chuan: "I don't have this idea for the time being. I should adopt another method for the sale of high-temperature copper-carbon-silver composite superconducting materials. The specific situation will be announced later. Next."

Immediately, another raised arm was drawn by him, and a middle-aged man in his forties stood up.

"Hello, Professor Xu, I am the representative of AMSC Superconducting Corporation in the United States. I heard that the Chuanhai Materials Research Institute under your name has a mysterious mathematical model in material research. Are the artificial SEI films and high-temperature superconducting materials you are researching the same? What about the ability to rely on this model?"

As soon as this question came out, there was some commotion in the venue.

To the outside world, the Professor Xu standing on the podium is undoubtedly mysterious.

It is not much to say that he is at the pinnacle of the scientific community at the age of more than 20 years old. What is even more exaggerated is that he is also developing like a fish in water in the field of materials, which is completely different from mathematical physics.

Although there are not many achievements at present, only artificial SEI thin films and 152K high-temperature superconducting materials, the importance of both materials can be said to subvert related industries.

Many people want to know his secret and how he researched these two materials.

In the past, these have always been attributed to the talent of geniuses, but now it seems that there is something else hidden?
