Luo Jia's words caused everyone to nod again and again, controllable fusion, magnetic restraint is the foundation, if the magnetic constraint is not up to standard, even if it is said to be wild, it can only be useless in the end.

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

Luo Jia boasted unashamedly, in fact, it didn't matter what the argument was, the important thing was that Luo Jia got the fusion device drawings and technology of the energy civilization from the hands of the black sword.

"In addition to the design, another difficulty in magnetic confinement is the superconducting material." Luo Jia said calmly: "The German stellar simulator uses expensive Nb-Ti, that is, niobium-titanium alloy, and the French International Thermonuclear Experimental Reactor ITER uses the more expensive Nb3Sn, that 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 it is also spectacular, and ITER is as spectacular, as well as the laser inertial confinement fusion in North America, codenamed NIF, because we rely on the Kármán vortex street power generation technology, the first to achieve energy freedom, North America has been a little anxious in recent years, and has invested heavily in the field of controlled fusion, so their laser inertial confinement technology has also made rapid progress."

"This is the increasingly fierce competition, whether we or the West, we have invested heavily in the field of fusion, and the next thing is to see who will die."

"Now let's go back to the aspect of superconducting materials, your predecessors should know that our materials science research institute of Xingchen Technology is the strongest on the earth, among which Dr. Ji Ming is responsible for carbon fiber and tri-titanium alloy, and Dr. Cao Yuan is responsible for graphene and nanotubes, they have all made achievements, and they are considered to be the first school in the field of materials science."

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

Hearing this, everyone's eyes suddenly lit up, speculating whether Xingchen Technology had made a breakthrough in superconductivity research.

Superconductors are a good thing, when the external magnetic field changes, it will induce currents, and these currents will not become smaller at all because the superconductor has no resistance, according to Lenz's law, the magnetic field generated by the current will prevent the magnetic field from changing, so the final effect is that the magnetic flux of the superconductor will never change.

Anyway, superconductor is a very awesome thing, and it has a wide range of applications, not only for controllable fusion, but also for all electricity-related technologies, such as maglev cars and maglev trains in science fiction movies, if there is no superconducting technology, it cannot be achieved at all, superconductivity is the pre-technology of advanced maglev.

In addition, Chao Anbang is not unknown, he is the youngest doctor of materials science in the century-old history of Tsinghua University, ordinary people may not have heard of Chao Anbang, this is normal, but in the circle, Cao Anbang's name has long been known.

After a pause, Luo Jia said: "I don't think that those superconducting materials that need to reach absolute zero in order to achieve zero resistance will have any future, after all, the condition of absolute zero is too harsh, and it has no meaning in reality, and our goal has always been clear, that is, to find a perfect material that has stable zero resistance, or close to zero resistance, no matter at any temperature." ”

"It's just that the requirements are too high, and the difficulty of research and development has become great, Chao Anbang led the team to pursue hard, and never found a way to achieve universal superconductors, and also paid a huge sacrifice, but there is no endless road, just when our superconducting project came to a standstill, 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 is in a building, and the researchers on both sides look down all day long and don't look up, which is very familiar, so Chao Anbang went to Cao Yuan, got a lot of graphene back, and tried to use graphene for experiments with the mentality of a dead horse as a live horse doctor, after all, graphene is a thing we can mass-produce, there are many, not rare, there is a way to get the moon first near the water."

"Now things become interesting, because of Cao Yuan's success, Chao Anbang jumped out of the circle of traditional superconductivity research, he did not use niobium alloys, nor copper oxides, but whimsically, using graphene from the laboratory next door for superconductivity tests."

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

"Have nothing to do, get a bunch of graphene to do superconductivity tests? Sure enough, it's 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 Xingchen Technology's graphene is so much that it can be measured in tons."

Everyone thought secretly in their hearts, and at the same time pricked up their ears and listened carefully, eager to know what the results of Chao Anbang's test were.

Luo Jia said with a smile: "At the beginning, the test did not go well, but I couldn't stand the nurse, Chao Anbang's good friend Cao Yuan enthusiastically assisted, while the superconducting laboratory was testing, the graphene laboratory also continued to update its own product line, graphene, tubular graphene, nanotubular graphene, double-layer graphene..."

"Chao Anbang was anxious, so he simply got all these graphene products back for experiments, and he accidentally discovered a strange phenomenon, when the double-layer graphene is close to one degree at the corner, the energy band structure will be close to a zero-dispersion energy band, which will lead to a metal insulator when this energy band is filled halfway, and finally transformed into a Mott insulator."

"At the earliest, we observed similar transitions in copper oxides, so copper oxides have always been the most popular research direction for high-temperature superconductivity, and there are at least hundreds of laboratories in China and even around the world that use copper oxides to carry out superconductivity research."

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

When Luo Jia faces many experts and scholars, the content of his speech will inevitably enter the professional depth, which is different from his weekly column program, which is for the people to see, requiring Luo Jia to speak human words, and many scientific predecessors are here, Luo Jia does not need to speak in a simple and understandable way, only needs to be professional and rigorous.

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

Luo Jia's speech began to speed up a little and said: "We currently call this technology superconducting induction technology, in short, through chemical splicing with other elements, to induce the superconductor state of graphene. ”

With atomic-level chemical splicing, the superconductor state is induced!?

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 matter on Earth?

Then use chemical splicing to induce the characteristics of superconductors!

Seriously, if Luo Jia hadn't spent seven years constantly learning the inheritance of the Golden Dome, how could he believe this kind of magical thing that obviously violates the laws of physics and is infinitely close to metaphysics.

"In order to accelerate the space program, more black technologies must be thrown." Luo Jia looked at everyone's reactions, and secretly thought in his heart, "It seems that the current earth science community has not yet reached the level of being able to accept advanced extraterrestrial science, but for the sake of the stars and the sea, I can only ask you to get on the bus quickly." ”

Boom~

Perhaps the superconductivity induction theory is too amazing, and almost immediately, everyone raised their hands, hoping to ask Luo Jia a question.

Thinking of explaining a lot of problems, Luo Jia also had a headache.

Just then, a shrill ticking sound sounded, it was the signal sent by Dr. Xie Tian from the fusion reactor, and the last fifteen minutes countdown.

Just when everyone forgot to listen to Luo Jia's explanation, the time had quietly come to the early hours of the morning, and the first controllable fusion experiment in the history of Xingchen Technology was about to be officially launched!

"The experiment is about to start, if there is any problem, let's wait until the experiment is over."

Luo Jia said, raised his legs and walked towards the monitoring room, although the bigwigs of the two courtyards were itchy and uncomfortable, they couldn't say anything, so they had to follow Luo Jia with a stomach full of confusion.

In March of the seventh year of the establishment of Xingchen Technology, the controllable fusion experiment is about to begin.
