If you have noticed in daily life, some wine cabinets, water dispensers, car refrigerators, etc. are quiet "workers". They do not have a buzzing compressor, but rely on a piece of thermoelectric material to achieve thermal insulation and cooling. In car refrigerators, thermoelectric materials use current to generate heat absorption effect, so as to exert the cooling function.

Another application scenario for thermoelectric materials is temperature differential power generation, so high-temperature thermoelectric materials such as niobium, cobalt and antimony are also "dry food" for interstellar travel. During the long-lasting interstellar voyage, outer space probes or spacecraft cannot get sunlight supply, so they must bring their own "dry food" - nuclear materials. In the cold deep space of the universe, temperature differential power generation can be achieved with the help of high-temperature thermoelectric materials.

No wonder Li Chuan came here in person. Professor Zhu Juntie's research results are not only crucial to the geothermal energy mining of the "South and North Transmission" project, but in his private space blueprint in the future, niobium, cobalt and antimony alloy is also a very important material in interstellar travel. This new high-temperature thermoelectric material must be needed to go to deep space.

It is worth mentioning that the name Half Hesler alloy comes from Conrad Hesler, a mining engineer in the 19th century. He accidentally discovered that the alloy would produce magnetic properties by making copper, manganese and tin without magnetic properties in a ratio of 2:1:1, and the alloy would produce magnetic properties. It was named Hesler alloy.

The alloy synthesized at a ratio of 1:1:1 is called semi-Hessler alloy.

Many semi-Hessler alloys have semiconductor characteristics and can show excellent thermoelectric properties, outstanding stability and mechanical properties. They are high-quality thermoelectric materials, while niobium, cobalt and antimony alloys are the top among excellent thermoelectric materials.

Temperature differential power generation may be the only energy supply solution in the field of deep space exploration, which shows the importance of niobium, cobalt and antimony alloys in the future.

When Li Chuan held the transparent tube in his hand and looked at the alloy substance inside, Professor Zhu Juntie beside him couldn't help but say: "In the semi-Hessler alloy family, there is a clear dividing line. The alloy with an outer electron number of 18 can form a stable cubic crystal structure and exhibit semiconductor characteristics; while the outer electron number of 17 or 19 is metal. Thermoelectric materials are all semi-Hessler alloys from the 18 electronic system."

"The number of electrons in the outer layer of niobium cobalt and antimony alloy of 1:1:1 is 19, and most scientists calibrate it as a metal, but the 'personality' of this metal tends to be semiconductors. Although the outside world believes that this, I firmly believe that the number of electrons in the outer layer of niobium cobalt and antimony is true 18 and false 19."

Now that the mystery has been revealed, Professor Zhu Juntie has produced alloys that foreign scientists firmly believe do not exist.

Li Chuan submitted the alloy sample to the staff, and then Professor Zhu Juntie took him to another room in the laboratory, where there was an advanced magnetic levitation refining instrument and equipment.

It is like a magnetic field-driven agitator, using the magnetic field to generate eddy currents, and while melting the metal raw materials and suspending them in the container, it continues to "stir" to achieve maximum homogeneous mixing.

It was precisely using this equipment that Professor Zhu Juntie obtained ultra-high purity niobium cobalt antimony alloy material, and this research project also received strong support from the National Natural Science Foundation and the Huasheng Science and Technology Incubation Institute.

After leaving the laboratory, Li Chuan, Zhu Juntie and others discussed the mass production of niobium, cobalt and antimony alloys. The geothermal energy mining of the "South and North Vehicles" project, its mechanical and electrical equipment requires a large amount of niobium, cobalt and antimony alloy materials, and this matter must be started quickly.

The final result of the negotiation was to establish a joint venture project enterprise, with a joint investment of 40 billion yuan from the National Natural Science Foundation of China, Zhejiang University National Key Laboratory and Huasheng Science and Technology Incubation Institute jointly invested 40 billion yuan as registered capital, while the three parties accounted for 30% of the shares. Professor Zhu Juntie would have had 5%, which is also worthy of income.

But he didn't want it and handed it over to the country directly, saying that the country needs money for scientific research and development, and that he has enough salary and benefits. The country cannot let himself starve to death. Why do you need so much money?

I have to say that this is the true unparalleled national warrior, which is admirable. There are too many scholars like him who are indifferent to fame and fortune. Their only demand is that they can be in the scientific cause, which is enough.

In the end, Professor Zhu Juntie named the director of the technical department and put forward the schedule for mass-producing niobium, cobalt and antimony alloy materials as soon as possible.

In the afternoon, Li Chuan stayed at Zhejiang University for a long time. After discussing the matter here, he decided to leave after he decided on some key matters.

As soon as he came out, he was surrounded by a large army of crazy reporters who rushed over early and rushed over. Fortunately, there were a large number of agents and bodyguards accompanying him, which did not affect Li Chuan.

It is too difficult to interview this top celebrity now. He has almost no road surface, and the ones he has the opportunity to interview are all official media, and it is also on specific projects. Usually, the official media can't interview them.

"Mr. Li, what impact will the Northwest renovation project have on our country's environmental problems?"

"Mr. Li, what are your responses to the widespread spread of fully automated industrial robots and the widespread rise in unemployment rates in major factories and workshops?"

"Mr. Li, what are your responses to the many voices at home and abroad calling for full ban on robots from snatching human work?"

"Mr. Li, please ask..."

...

As the army of crazy reporters surrounded him, problems followed one after another. Li Chuan's ears felt like he was drowned by the chirping sounds of problems. Fortunately, the accompanying security brigade used his body as a flesh wall to block the crazy reporters, forming a smooth passage in the middle.

Li Chuan heard most reporters asking questions about intelligent robots. He wanted to leave directly. His time was really precious, but when he heard the mainstream voices like this, he chose to stop on his own initiative.

The reporters at the scene couldn't help but lit up when they saw him stopping. Is he going to be interviewed?

Seeing this, the agents and bodyguards around him immediately made conscious adjustments. Xu Qingyun and other personnel who were accompanying him tapped the headset communicators on their ears to conduct security communication arrangements.

At this time, as Li Chuan stopped, the reporters at the scene stopped asking questions in a tacit understanding, and handed the microphone toward Li Chuan. The latter looked around everyone, thinking about most of the mainstream voices before, and then said:

"I often hear media reports after the New Year that companies are difficult to recruit workers, especially coastal processing and manufacturing bases. In recent years, over the past decade, there have been difficulties in recruiting workers."

"Recalling twenty or thirty years ago, those born in the 1970s and 1975s had to ask their acquaintance to enter a decent factory site. But now, it has long been reversed. Few or even fewer young people want to go to factories to be workers. Bosses lose hair a lot in order to recruit people, including the hottest construction industry, and this situation has also occurred in recent years!"

Speaking of this, Li Chuan said bluntly to a news media worker: "Many news media always report on labor shortage, but never conduct front-line questionnaires and never interview those front-line workers in depth. If you don't go to the front-line interviews, how can you know the real reason for the labor shortage? How can you know where the young people who don't enter the factory go?"

Is there such a sexy operation? The media people at the scene were confused. Boss Li, why did you aim your firepower at us?
