Chapter 352 The Sound of the Fourth Industrial Revolution

Kelvin didn't care about the performance of others.

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.

Compared with chatting with this colleague, he hopes to have a chance to talk with 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 and manufactured, he wants to get a chance to cooperate.

If this high-temperature superconducting material cannot be industrialized and used commercially 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 to industrialize the production of this material.

If this high-temperature superconducting material can already be industrialized and used commercially, then they must get a chance to cooperate.

At normal pressure, 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 the superconducting materials in the world.

Nexans is a large company, one of the Fortune 500 and one of the top ten integrated wiring brands in the world. 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 ranked first or second in the world.

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

Superconducting materials are a revolution. With its development, those backward enterprises will eventually be forgotten.

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

The first was in the British Empire, where the development of steam engines and related technologies almost allowed the British Empire to rule the world;

The second was in Europe and the United States, where the development of electricity, internal combustion engines and chemical industries made machine production more efficient and large-scale, further promoting the process of industrialization and allowing Europe and the United States to stand at the top of the world;

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

Historically, each industrial revolution lasted about a hundred years, and each time there would be one or more scientists leading the era in the field of science.

To date, the third industrial revolution has been developing for more than eighty years, and 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, he seems to be like a legendary scientist in history. In the dark, Kelvin Noah seems to have heard the sound of the opening of the fourth industrial revolution.

At 10 o'clock in the morning, the press conference on high-temperature copper-carbon-silver composite superconducting materials officially began.

Xu Chuan walked up to the podium with steady steps, and behind him, the huge silver-white projection screen opened.

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

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

As he took the stage, the originally slightly noisy venue suddenly became quiet, leaving only the sound of the camera's "clicking".

Standing in front of the podium, Xu Chuan looked at the crowd below and said, "First of all, welcome everyone to come here from afar to attend today's press conference."

"The theme of today's report is just as the screen behind me shows, it is the press conference of the latest achievement of Sichuan Hai Materials Research Institute, 'High-temperature copper-carbon-silver composite superconducting materials'."

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

"Superconducting materials and superconducting technology are one of the greatest discoveries of the 20th century. It has extremely excellent performance and broad application prospects."

"Since 1911, when physicist Onnes discovered 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 in physics research and material research."

"However, it is difficult to achieve superconductivity, and it requires extremely low temperatures to achieve it, which limits its wide application in practical applications."

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

"Under normal pressure, the Tc critical temperature of 152K is the first report submitted by the Sichuan Hai Materials Research Institute and me on this road."

"I believe that everyone here has obtained some of the relevant properties of this material from the invitation letter or other channels before coming here, so I won't keep you in suspense."

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

The projection screen behind him jumped and a table appeared on the screen.

[Critical temperature (Tc): 152.7K]

[Critical magnetic field (Hc): At 152K, Hc is 20.142T, 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 was displayed on the screen one by one. The representatives of the manufacturers who saw this form in the audience took a deep breath at the same time.

As representatives arranged by the superconducting material company to attend today's report meeting, everyone knew the meaning of the data on this form.

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

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, critical current/current density are almost crushed.

If there is a disadvantage, it is that there are some deficiencies in some aspects of conventional physical properties.

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

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

At least, in the large particle collider, medical equipment, maglev trains and other equipment with stable use environment or using plates as superconducting instruments, there is no problem at all.

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 anti-magnetism of superconducting materials to manufacture some precision instruments, such as frictionless gyroscopes, bearings and other equipment.

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

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

So if you can provide this material 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 troublesome point. But this is basically not a problem for major manufacturers. No matter how strange the shape is, as long as someone needs it and there is money to be made, they can find ways to make it.

Without wasting too much time at the press conference, Xu Chuan began to wrap up in about half an hour.

"Today's press conference is here."

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

After the words fell, someone in the audience raised his hand and stood up.

Xu Chuan motioned the staff to hand over the microphone.

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

When this question was raised, all the representatives of the manufacturers in the venue pricked up their ears.

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

On the podium, Xu Chuan said, "At present, high-temperature copper-carbon-silver composite superconducting materials have not entered mass production. I am looking for methods and cooperative enterprises to mass produce it."

As soon as the voice fell, 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: "Excuse me, Professor Xu, regarding this high-temperature superconducting material, will you apply for a patent and then sell the patent license 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 the high-temperature copper-carbon-silver composite superconducting material. The specific situation will be announced after it is decided. Next."

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

"Hello, Professor Xu, I am a representative of AMSC Superconducting Company in the United States. I heard that your Chuanhai Materials Research Institute has a mysterious mathematical model for material research. Do the artificial SEI 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.

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

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

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

Many people want to know his secrets and how he developed 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 going on?
