Kelvin didn't care about the other people's performance.

In addition to wanting to see the performance and data of this high-temperature copper-carbon-silver composite superconducting material, everyone who came here today is actually a potential competitor.

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

Regardless of whether the high-temperature copper-carbon-silver composite superconducting materials researched by Professor Xu can be commercially manufactured, he wants to get an opportunity to cooperate.

If this high-temperature superconducting material cannot be industrialized and commercialized at present, he can talk to Professor Xu on behalf of Nexans to see if they can reach a cooperation and let them study the way of industrial production of this material.

If this high-temperature superconducting material can already be industrially produced and used commercially, then they will have to get an opportunity to cooperate.

In the atmospheric state, the superconducting temperature of 152K, 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 superconducting materials in the world.

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

Many of its products, such as winding wires, submarine cables, data cables, power cables, etc., are in the first or second place 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 backward companies will eventually be dusted.

Over the past two hundred years, several industrial revolutions have created several different powerful nations.

For the first time in the country where the sun never sets, the development of the steam engine and related technologies made the empire of the sun never set almost dominate the world;

For the second time, the development of electricity, internal combustion engines and chemical industries in Europe and the United States made machine production more efficient and large-scale, thus further promoting the industrialization process and making Europe and the United States stand at the top of the world;

The third time occurred in the middle of the 20th century to the present, led by the development of computer, Internet and communication technology to make machine production more intelligent and automated, thus promoting the process of digitization and informatization.

Historically, each industrial revolution lasted for about 100 years, and each time there were one or more scientists who led the era in the field of science.

Today, the Third Industrial Revolution has been developing for more than 80 years, and it is visible to the naked eye that it has come to an end.

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

Coupled with the appearance of Professor Xu, in today's scientific community, the perverted scar of the historical scientists, Kelvin Noah seems to have heard the wave of the beginning of the fourth industrial revolution.

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

Xu Chuan walked onto the podium calmly, and behind him, the huge silver-white projection screen opened.

【152K, high-temperature copper-carbon-silver composite superconducting material】

A line of bilingual titles appears on the screen, with a silver-grey film swirling in the center of the screen, representing today's theme.

As he took the stage, the originally slightly noisy venue instantly fell silent, 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, welcome everyone who has traveled thousands of miles here to participate in today's press conference. ”

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

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 twentieth century, with excellent properties and broad application prospects."

"Since 1911, when physicist Annis discovered that the resistance of mercury suddenly drops to zero when the temperature drops to 4.15 K, superconducting materials have become a hot field in physics and materials research over the past few decades."

"However, superconductivity is difficult to achieve and requires extremely low temperatures to achieve, thus limiting its wide range of applications in practical applications"

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

"The atmospheric pressure state, the critical temperature of 152K Tc, is the first answer sheet I handed in on this road."

"I believe that all of you here have obtained some of the relevant properties of this material from the invitation letter or other means before coming, so I will not be appetizing."

As he spoke, Xu Chuan pressed the remote control pen in his hand.

The projection screen behind him jumps, and a table appears 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): It can reach 5500A/mm2 at 20T. 】

【Critical Current Density (Jc):】

[Thermal conductivity: 572.3W/m·k]

【. 】

The test data of each item was displayed on the screen, and the representatives of the manufacturers who saw this form in the audience gasped involuntarily at the same time.

As a representative of Superconducting Materials Company who arranged to attend today's report meeting, everyone is well aware of the significance of the data on this form.

It is no exaggeration to say that this is a new material that disrupts 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 there is a downside, it is that there are some deficiencies in some aspects of general physical performance.

Although copper oxide-based high-temperature superconducting materials are also ceramic, some of its composite materials are beyond this material in terms of toughness, brittleness, stiffness, fatigue strength, etc.

However, if it is said that compared with the excellent performance of this material in terms of super-large performance, it is not unacceptable that it has some defects in its physical properties.

At the very least, there is no problem at all in the use of equipment such as large strong particle colliders, medical equipment, and maglev trains, or the use of plates as superconducting instruments.

In addition, although this high-temperature copper-carbon-silver composite superconducting material is highly brittle, it does not have much problem in using the complete diamagnetism of superconducting materials 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.

It's like jade, unless you take it and smash it on the ground or something, just play with it in your hand or wear it, it won't break.

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

Of course, if shaping is a trouble spot. But this is basically not a thing for major manufacturers. No matter how strange the shape is, as long as someone needs it, as long as there is money to be made, they can try their best to make it.

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

"That's all for today's press conference."

"Next, if you have any questions about the 'high-temperature copper-carbon-silver composite superconducting material' developed by our Sichuan Sea Materials Research Institute, you can put it forward now."

As soon as the words fell, someone in the audience raised their hands and stood up.

Xu Chuan motioned for the staff to hand over the microphone.

The question was asked by a middle-aged man, dressed in a suit and leather shoes, and he said: "Hello Professor Xu, I am the representative of the SuperPower Research Institute of Furukawa Company, I would like to ask, about this high-temperature copper-carbon-silver superconducting material, is it ready for mass production?" ”

This question was raised, and all the representatives of manufacturers in the room pricked up their ears.

Without a doubt, this is the most critical issue for all of you present.

On the podium, Xu Chuan said: "At present, high-temperature copper-carbon-silver composite superconducting materials have not yet 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 were quickly raised.

Xu Chuan casually smoked one, and the other party quickly stood up and took the microphone from the staff: "May I ask Professor Xu, about 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 take another way to sell high-temperature copper-carbon-silver composite superconducting materials, and announce it after the specific situation is decided." Next. ”

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

"Hello Professor Xu, I am the representative of AMSC Superconducting Company in the United States, I heard that the Chuanhai Institute of Materials under your name has a mysterious mathematical model for materials research, do the artificial SEI thin films and high-temperature superconducting materials you study rely on the ability of this model?"

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

To the outside world, there is no doubt that Professor Xu standing on the podium is mysterious.

It is not much to say that he is standing at the pinnacle of the scientific community at the age of 20, and what is even more exaggerated is that he has also developed like a fish in water in the field of materials, which is completely different from mathematical physics.

Although there are only two achievements so far, artificial SEI thin films and 152K high-temperature superconducting materials, the importance of both materials can be said to be disruptive in related industries.

Many people want to know his secrets and how he came up with these two materials.

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

PS: The second more asks for a monthly pass!
