Chapter 506: Fusion experiments and superconducting induction technology!

Luo Jia's words drew everyone's nods and controlled fusion. Magnetic confinement was the foundation. If the magnetic confinement did not meet the standards, even if it was said to be sky-high, it would only be useless.

众所周知 "As we all know, after repeated demonstrations, we finally chose the double helix stellar. This new design is undoubtedly an epoch-making masterpiece ..."

Luo Jia bragged loudly, but in fact it was not important to prove anything. What was important was that Luo Jia obtained the drawings and technology of the energy civilization fusion fuse from the hands of the Black Sword.

"In addition to design, another difficulty in magnetic confinement is superconducting materials." Luo Jia calmly said, "The German star simulator uses expensive Nb-Ti, which is niobium-titanium alloy, and France's international thermonuclear fusion. The experimental reactor ITER uses the more expensive Nb3Sn, a niobium tritin compound superconductor. "

"In addition, I must say that the design weight of ITER has reached a crazy 23,000 tons, equivalent to three Eiffel Towers. It is really expensive and spectacular, as spectacular as ITER, and the one in North America. Laser inertial confinement fuse, code-named NIF, because we rely on Carmen Vortex power generation technology to take the lead in achieving energy freedom. North America has been anxious in recent years, and has invested heavily in the field of controlled fusion. Therefore, their laser inertial confinement technology has improved very fast."

"This is the increasingly fierce competition. Both us and the West have invested in the field of fusion, and then we will see who is dead."

"Now let us return to the superconducting material aspect. Everyone should know that our Star Science Institute of Materials Science is the strongest on the planet. Among them, Dr. Ji Ming is responsible for carbon fiber and trititanium alloy, and Dr. Cao Yuan is responsible for graphite. Ene and nanotubes, they have already made achievements, and they are considered to be pioneers in the field of materials science. "

"But you may not know that we at the Academy of Materials Science and another Dr. Chao Anbang, who joined the company earlier than Cao Yuan, but has been obscure, sticking to important positions in materials science, superconductors."

When I heard this, everyone's eyes suddenly turned on, speculating whether Xingchen Technology had made a breakthrough in the superconducting research.

Superconductors are a good thing. Currents are induced when the external magnetic field changes, and these currents do not become small because the superconductors have no resistance. According to Lenz's law, the magnetic field generated by the current will prevent the magnetic field from changing, so the final The effect is that the magnetic flux possessed by a superconductor will never change.

Anyway, superconductors are very powerful and have a wide range of applications, not only for controlled fusion, but also for all electrical-related technologies, such as maglev cars and maglev trains in science fiction movies. Guide is the advanced technology of advanced maglev.

In addition, Chao Anbang is not unknown. He is the youngest PhD in materials science in Tsinghua's 100-year history. Ordinary people may not have heard of Chao Anbang. This is normal, but in the circle, the name of Cao Anbang has long been known. .

After a pause, Luo Jia said, "I don't think there is any future for superconducting materials that need to reach absolute zero to achieve zero resistance. After all, the condition of absolute zero is too harsh. In reality, there is no Meaning, our goal has always been clear, and that is to find a perfect material that has stable zero resistance, or near zero resistance, at any temperature. "

"It ’s just that the requirements are too high, the research and development difficulty becomes very great. Chao An led the team to pursue hard, never found a way to achieve a universal superconductor, but also paid a huge sacrifice. When the superconducting project of China was in stagnation, Cao Yuan's team completed the graphene preparation process, and we can produce graphene on a large scale. "

"Chao Anbang and Cao Yuan's team are in a building. Researchers on both sides have bowed their heads all day without seeing each other. They are very familiar. So Chao Anbang went to Cao Yuan, got a lot of graphene back, and held him dead. When the mentality of the horse is alive, try to use graphene as an experiment. After all, we can mass produce graphene. It is not rare, but it is near the water tower. "

"This thing became interesting because Cao Yuan's success led Chao Anbang to jump out of the traditional superconducting research circle. He did not use niobium alloys or copper oxides. Instead, he was whimsical and took the laboratory next door. Graphene for superconductivity tests. "

Luo Luojia, like telling a story, is talking about the interesting things happening in the company, and everyone's heart is mentioned at the moment.

"Nothing to do, get a bunch of graphene for superconductivity tests? It really is Xingchen Technology's whimsical style."

"People are more deadly than popularity. In most laboratories, it is not easy to find a few grams of graphene, but Star Technology has more graphenes than tons."

Everyone thought in their hearts secretly, and at the same time raised their ears to listen carefully, eager to know what the test results of Chao Anbang were.

Luo Jia said with a smile: "At the beginning, the test did not go smoothly, but there was no nurse. The good friend of Anbang Cao Yuan assisted enthusiastically. As the superconducting laboratory tests, the graphene laboratory is constantly updated. Own product lines, graphene, tubular graphene, nanotubular graphene, double-layer graphene ... "

"Chao Anbang was so anxious that he simply took all these graphene products back for experiments. He accidentally discovered a strange phenomenon. When the angle of the double-layer graphene was close to one degree, the band structure would be close to zero. Dispersive energy bands, so that when this energy band is half filled, it will pass through a metal insulator and eventually become a Mott insulator. "

"At the earliest, we observed similar transformations in copper oxides, so copper oxides have always been the hottest research direction for high temperature superconductivity. There are at least hundreds of laboratories in China and the world, using copper oxides to conduct superconductivity. the study."

"Now, we have obtained similar results by changing the angle of double-layer graphene. The most important significance is not that we use graphene as a superconductor, but it provides an unprecedented research direction. Using cold atom systems, simulations A superconducting phase obtained by doping a Mott insulating phase. "

When Luo Jia faces many experts and scholars, the content of his speech will inevitably go into professional depth. This is different from his weekly column program. The column is for the general public and requires Luo Jia to speak, and many scientific seniors Here, Luo Jia does not need to be easy to understand, but only needs professionalism and rigor.

If you translate Luo Jia's speech into adult words, when a material cannot become a superconductor, try to stack the materials, and then twist it. The materials that are not aligned and stacked may show the magical characteristics of superconductors.

Luo Luojia began to speak a little faster, saying: "We currently call this technology superconducting induction technology. In simple terms, through the chemical splicing with other elements, the superconducting state of graphene is induced."

Use atomic-level chemical splicing to induce a superconductor state! ?

The crowd at the scene was shocked again. This was an unforgettable night. In just a few hours, Luo Jia led a group of academicians and experts to appreciate the magical charm of advanced science beyond the stars.

不是 Aren't there no superconducting substances on the earth?

Then use chemical splicing to induce superconductor characteristics!

I honestly believe that, if Luo Jia had not been studying the inheritance of the golden dome for the entire seven years, how could he believe this magical thing that apparently violated the laws of physics and infinitely close to metaphysics.

"In order to accelerate the space program, more black technologies must be thrown out." Luo Jia watched everyone's reactions and thought to himself, "It seems that the current earth science community has not reached the level of accepting advanced asteroid surgery, but in order to Xingchen Dahai ~ EbookFREE.me ~ I can only ask everyone to hurry up. "

Hey lala ~

Perhaps the theory of superconductivity induction is too amazing. Almost everyone raised their hands for the first time, hoping to ask Luo Jia questions.

Luo Jia also had a headache thinking about explaining a lot of problems.

At this time, a harsh dripping sound sounded. It was a signal from Dr. Xie Tian from the fusion reactor. The last fifteen minutes counted down.

When everyone forgot to listen to Luo Jia ’s explanation, time has quietly arrived in the early morning. In the history of Xingchen Technology, the first controllable fusion test is about to begin!

"The experiment is about to start. If there is any problem, let's talk about it after the experiment is over."

Luo Luojia said, and walked up to the monitoring room. Although the big brothers of the two hospitals felt itchy and uncomfortable, they couldn't say anything else, so they had to follow Luo Luo with confusion.

Xingchen Technology was established in March of the seventh year, and the controllable fusion test is about to begin.
