Technological Hegemony

Luo Jia's words drew everyone's nods. Controlled fusion is based on magnetic confinement. If the magnetic confinement is not up to standard, no matter how extravagant the talk is, it will be useless in the end.

"As we all know, after repeated arguments, we finally chose the double-helix stellarator. This brand-new design is undoubtedly an epoch-making masterpiece..."

Luo Jia boasted brazenly. In fact, the argument is not important. The important thing is that Luo Jia got the fusion device blueprint and technology of energy civilization from Hei Jian.

"Besides design, another difficulty of magnetic confinement lies in superconducting materials." Luo Jia said calmly: "The German stellarator uses expensive Nb-Ti, which is niobium-titanium alloy, and the French international thermonuclear fusion The experimental reactor ITER uses more expensive Nb3Sn, which is a niobium-tritin compound superconductor."

"In addition, I must say that the design weight of ITER has reached a crazy 23,000 tons, which is equivalent to three Eiffel Towers. It is really expensive and spectacular. As spectacular as ITER, there is also the one in North America. Laser inertial confinement fusion, code-named NIF, because we rely on Karman vortex street power generation technology, we took the lead in realizing energy freedom. North America has been a little anxious in the past few years and has invested heavily in the field of controllable fusion. Therefore, their laser inertial confinement technology has also made progress. very fast."

"This is an increasingly fierce competition. Both we and the West have invested heavily in the field of fusion, and the next step is to see who wins."

"Now let's go back to the aspect of superconducting materials. Seniors should know that the Institute of Materials Science of our Star Technology is the strongest on earth. Among them, Dr. Ji Ming is in charge of carbon fiber and tri-titanium alloy, and Dr. Cao Yuan is in charge of graphite. Alkenes and nanotubes, they have both made achievements, and they are considered to be the first in the field of materials science."

"But you may not know that there is also a Dr. Chao Anbang in our Institute of Materials Science. He joined the company earlier than Cao Yuan, but he has been unknown, sticking to an important position in the field of materials science, superconductors."

Hearing this, everyone's eyes lit up immediately, wondering whether Xingchen Technology had made a breakthrough in the research of superconductivity.

Superconductors are a good thing. When the external magnetic field changes, currents will be induced, and these currents will not become smaller because 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 never changes.

Anyway, superconductor is a very powerful thing with a wide range of applications. It is not only needed for controllable fusion, but also for all electricity-related technologies, such as maglev cars and maglev trains in science fiction movies. Without superconducting technology, it is impossible to achieve. Guidance is the pre-technology of advanced maglev.

in addition,

Chao Anbang is not unknown. He is the youngest Ph.D. in materials science in the century-old history of Tsinghua University. Ordinary people may not have heard of Chao Anbang, which is normal, but Cao Anbang's name has long been known in the circle.

After a pause, Luo Jia continued: "I don't think there will be 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, and there is no such thing in reality. Meaning, our goal has always been clear, that is to find a perfect material that has stable zero resistance, or close to zero resistance at any temperature."

"It's just that the requirements are too high, and the difficulty of research and development becomes very high. Chao Anbang led the team to pursue hard, but never found a way to realize a universal superconductor, and it was a huge sacrifice. When the superconducting project in China stalled, Cao Yuan's team completed the graphene preparation process, and we can mass-produce graphene."

"The teams of Chao Anbang and Cao Yuan were in the same building. The researchers on both sides kept their heads down all day and didn't look up. They were very familiar with each other, so Chao Anbang went to Cao Yuan, got a lot of graphene and came back, hugging him to death. With the mentality of being a living horse doctor, try to use graphene for experiments. After all, we can mass-produce graphene, and there are so many of them.

"Now things become more interesting. Because of Cao Yuan's success, Chao Anbang jumped out of the circle of traditional superconductivity research. He didn't use niobium alloys or copper oxides, but whimsical, and took the laboratory next door. Graphene for superconductivity experiments."

Luo Jia seemed to be telling a story, talking about interesting things that happened in the company, and everyone's hearts were raised at this moment.

"I have nothing to do, just make a bunch of graphene to do superconductivity experiments? It really is the whimsical style of Xingchen Technology."

"People are more popular than people. In most laboratories, it is not easy to find a few grams of graphene, but Star Technology's graphene is as much as tons."

Everyone thought to themselves, and at the same time pricked up their ears to listen carefully, eager to know the results of Chao Anbang's experiment.

Luo Jia said with a smile: "The experiment didn't go well at first, but we couldn't stand the nanny, Chao Anbang's good friend Cao Yuan enthusiastically assisted, while the superconducting laboratory was conducting experiments, the graphene laboratory was also constantly updated. Own product line, graphene, tubular graphene, nanotubular graphene, bilayer graphene..."

"Chao Anbang was overwhelmed, so he simply took all these graphene products back for experiments. He accidentally discovered a strange phenomenon. When the corner of double-layer graphene is close to one point one degree, the energy band structure will approach zero. Dispersed energy bands, so that when the energy band is half filled, it will pass through a metal insulator and finally transform into a Mott insulator."

"We first observed similar transformations in copper oxides, so copper oxides have always been the most popular research direction for high-temperature superconductivity. There are at least hundreds of laboratories in China and even the world, using copper oxides to develop superconductivity. Research."

"Now, we have obtained similar results by changing the rotation angle of bilayer graphene. The most important significance is not that we use graphene as a superconductor, but provides an unprecedented research direction, using cold atomic systems to simulate A superconducting phase obtained by doping the Mott insulating phase."

When Luo Jia faced many experts and scholars, the content of his speech would inevitably go into a professional depth. This was different from his weekly column program. The column was for the general public and asked Luo Jia to speak in human terms. Here, Luo Jia does not need to be easy to understand, but only needs to be professional and rigorous.

If Luo Jia's speech is translated into human words, it means that when a material cannot become a superconductor, try to stack the materials and then twist them. The non-aligned stacked materials may show the magical properties of superconductors.

Luo Jia began to speak faster and said: "We currently call this technology superconductivity induction technology. Simply put, the superconductor state of graphene is induced by chemical splicing with other elements."

Using atomic-level chemical splicing to induce a superconducting state! ?

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

Isn't there no naturally occurring superconducting material on the earth?

Then use chemical splicing to induce superconducting properties!

To be honest, if Luo Jia hadn't spent seven years continuously studying the inheritance of the golden dome, how could he believe in this magical thing that obviously violates the laws of physics and is infinitely close to metaphysics.

"In order to speed up the space program, more black technologies must be thrown out." Looking at everyone's reactions, Luo Jia thought to himself, "It seems that the earth science community has not yet reached the level where it can accept advanced extraterrestrial science, but for the sake of The sea of ​​stars, I can only ask everyone to get in the car quickly."

clatter~

Perhaps it was because the theory of superconductivity induction was too amazing. Almost immediately, everyone raised their hands, hoping to ask Luo Jia a question.

Thinking of explaining a lot of questions gave Luo Jia a headache.

Just at this time, a piercing beep sounded, which was a signal from Dr. Xie Tian from the fusion reactor, and the last fifteen minutes counted down.

Just when everyone was listening to Luo Jia's explanation, the time had quietly arrived in the early morning, and the first controllable fusion experiment in the history of Xingchen Technology was about to officially start!

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

After Luo Jia finished speaking, he raised his legs and walked towards the monitoring room. Although the leaders of the two houses felt itchy and uncomfortable, they couldn't say anything more, so they followed Luo Jia with a full stomach.

In March of the seventh year of Star Technology's founding, the controllable fusion experiment is about to begin.
