From Almighty Scholar to Chief Scientist

This test device can monitor various data such as the resistance of the tested conductor, and is very accurate, and can measure a resistance value of 0.000001.

Then, he pulled on the switch, and the current passed through the entire circuit in an instant. However, the value on the meter was still zero.

Seeing this scene, Lin Xiao frowned, and then sighed in his heart.

What an amazing scene.

At this time, the temperature in the laboratory is 25 degrees Celsius, which is a very standard room temperature, and the air pressure is basically a standard atmospheric pressure, without much difference.

But this black conductor has achieved superconductivity in this environment.

Although this scene is very scientific, in Lin Xiao's view, it is still very scientific.

Perhaps such a short section of room-temperature superconductor cannot be used to build cables or do other things. However, if it is wound into a ring and then a current is passed into it, when the critical current is reached, it will become a superconductor. Strong energy storage device.

This is superconducting energy storage.

Superconductors are not without resistance, but the resistance is so low that it takes at least 10 years for the current in them to be completely exhausted.

In this way, superconductors make excellent energy storage devices.

For example, it can store excess power generation during the low power consumption period, and then release it directly and instantaneously during the peak power consumption period to relieve the pressure on power generation.

Of course, this is only for civilian use, and if it is for military use, since the huge electric current stored in it can be sent out instantly, it is obvious that it has become the best carrier of energy for laser weapons, and the huge electric energy can instantly bring energy to the laser. Stronger energy, resulting in more destructive attacks.

In addition to this matter, superconductors can also be used to generate electricity, replacing the coils in the generator with superconducting coils can achieve lossless power generation!

And the size of the generator can also be made small, thereby reducing the energy consumption of driving the generator, and it can be used in more places in the future, such as on all-electric ships or cars.

In short, even such a small section of room temperature superconductor can play an extremely powerful role.

Thinking of the countless functions of room-temperature superconductors, Lin Xiao still couldn't calm down.

But soon, he fixed his eyes, "Okay, it's pointless to think so much, now it's time to test the specific performance."

The performance of superconductors, that is, critical temperature, critical current density, and critical magnetic field strength.

After the test soon, Lin Xiao's eyes lit up.

“69摄氏度的临界温度，4.514＊10^11A/m^2的临界电流密度，还有……19T的临界磁场强度！”

"Oh my god...my system!"

Lin Xiao's heart was full of excitement.

The critical temperature of 69 degrees means that the conductor does not even need to be set in a normal temperature environment when it is working. For example, when working in some high-temperature environments, the critical temperature of 69 degrees is enough for it to do more work.

而其4.514＊10^11A/m^2的临界电流密度，更是一个让林晓无比激动的数据，哪怕是铌钛合金最高都只能承受10^9A/m^2的临界电流密度，而这可是上百倍的差距！

As for its critical magnetic field strength of up to 19T, it directly reminded Lin Xiao of two things, one is a particle collider, and the other is magnetic confinement nuclear fusion!

Magnetic confinement nuclear fusion is a way to realize nuclear fusion. It uses a strong magnetic field to control the internal high-temperature plasma to achieve nuclear fusion power generation. The particle collider also uses a strong magnetic field to control the charged particles inside to collide.

At this time, the larger the magnetic field, the better it is naturally. For the former, the internal plasma can be better controlled. For the latter, a stronger magnetic field means stronger collision energy.

Regardless of whether it is CERN's LHC particle collider or Huaguo's magnetic confinement nuclear fusion tokamak device East Super Ring EAST, they all use niobium-titanium alloys to provide magnetic fields.

Niobium-titanium alloy can withstand a critical magnetic field strength of up to 10T, which means that it can only be used to generate a magnetic field of 10T, while the highest magnetic field strength of LHC is 8T, while the ring magnetic field strength of EAST is 3.5

And once they are replaced by the room temperature superconductor that Lin Xiao is holding now, their magnetic field strength will have a chance to be doubled.

Thinking of this, Lin Xiao's heart suddenly became more excited.

I didn't expect that the room-temperature superconductor that the system gave me was not only a room-temperature superconductor, but even a room-temperature superconductor with such strong basic performance.

This made him eager to see what this thing was made of.

As soon as he thought about it, he immediately took this thing and started to analyze the composition and structure.

First, use X-ray fluorescence spectroscopy to analyze its composition. It can be determined that this is an inorganic substance because there is no carbon inside. Then use XRD, that is, X-ray diffraction analysis method, to analyze the crystal phase, and then continue to use scanning electron microscope for microstructure. Come and observe.

Although Lin Xiao is familiar with it, it took a lot of effort to get the final result.

When seeing the final result, Lin Xiao couldn't help exclaiming: "This is actually a compound formed by combining iron-based substances and cuprates?"

He felt extremely surprised in his heart.

Can these two things be combined?

This is a compound, which can be classified as a pure substance, not a mixture like an alloy.

Lin Xiao felt that it was outrageous. Of course, it is understandable to think that this is a room temperature superconductor with such an incredible structure.

Even Lin Xiao felt a little lucky, after all, this meant that the room temperature superconductor, at least in terms of raw materials, was relatively cheap.

Of course, the production process also says that cheap raw materials do not mean that the final cost is also cheap. Silicon wafers are undoubtedly one of the examples.

"Hmm... It seems that we need to study how this thing is produced again."

Lin Xiao felt a headache again.

So reverse engineering is a very troublesome research project.

"It doesn't matter, just keep doing it."

Of course, at this time, he doesn't need to do it alone, he just needs to take out the microstructure and molecular formula, and then research it with others.

After all, even if others see this thing, they will not know its specific function for the time being.

So Lin Xiao made a choice, and finally chose Zhao Sheng, who he had worked with at the beginning. They had studied RDX crystals together.

After a phone call, Zhao Sheng, who was still celebrating Chinese New Year, was pulled over by Lin Xiao directly.

"My Director Lin, I'm teasing my granddaughter, so you just bring me here. If there's nothing important, I'm not finished!"

When he came to the laboratory, Zhao Sheng said with a smile.

Lin Xiao chuckled, and directly gave him the relevant information on iron-based cuprate: "Just this thing, I came to you just to get it out."

Seeing Lin Xiao's malicious look, Zhao Sheng took the information with some doubts, just glanced at it, and immediately complained: "Good guy, it's iron and copper acid, what the hell is this?" Stuff? It wasn’t enough to study an RDX pure silicon crystal with you last time, and now you are going to trouble me again, right? No, I won’t do it.”

Seeing Zhao Sheng like this, Lin Xiao guessed that he needed a brief explanation, so he said, "This is a high-temperature superconductor."

Zhao Sheng was taken aback for a moment, thinking that Lin Xiao was indeed researching superconductors recently, he immediately restrained himself, and then asked curiously: "What kind of high-temperature superconductor? You are iron-based and cuprate. ...Is it to solve the shortcoming that cuprate superconductors cannot be bent?"

Hearing Zhao Sheng's own message, Lin Xiao smiled and said, "Yes, according to my calculations, this thing can indeed solve that problem, so you can tell me whether you can do it or not?"

"Fuck it!"

Zhao Sheng immediately forgot what he said just now.

Just kidding, if a high-temperature superconductor that can be bent can be prepared, it will definitely be a more practical superconductor!

Of course he wouldn't miss this kind of thing.

Lin Xiao looked as if he was looking at the bait of a fish, and brought a non-disclosure agreement with a smile, "Then let's sign this thing first, and then prepare for it, so let's start researching it?"

Zhao Sheng nodded: "No problem!"

Chapter 332 It's bent!Really bent!

Research on the synthesis method of this iron-based cuprate will start soon.

How to combine these two things is undoubtedly full of challenges.

After all, this is not an alloy, and the strengthening is successful if copper and iron are smelted together.

How to form a chemical bond between these two things and then connect them together is very difficult.

And the time has come from the Spring Festival to the end of February, almost a month has passed.

"Well, according to the calculation of electron topological bonding theory, the replacement of oxygen atoms and the intervention of other impurities will cause distortion of the crystal lattice. This change is mainly reflected in the side length of the crystal lattice, and the change of the angle between the crystal planes is very small, so We can regard a, β, and v as keeping 90 degrees."

"Well, from the point of view of the partial wave density of state analysis, the oxygen atom in it has a strong localization, and its hybridization with other atoms around it mainly occurs at an energy of about -8eV."

In the laboratory, two people in white coats were communicating, and there were many other people in white coats around them.

This is the research team organized by Lin Xiao, which is responsible for overcoming this superconductor.

The two people who communicated were Lin Xiao and Zhao Sheng, and the others were assistant researchers.

For these ordinary researchers, it is obviously a good thing to be able to join Lin Xiao's team. At that time, they can get a little light on whatever they can do, so this is also one of the benefits of doing experiments at the Dingguang Research Institute. One, maybe one is lucky enough to get a project with their Director Lin.

For example, this time, according to Lin Xiao, the thing they are researching is a high-temperature superconductor, and it is still the kind that can be bent, and other critical parameters seem to be quite good. so big.

But the only problem is that this thing is a bit too difficult to handle.

These ordinary researchers were all sitting there, either scratching their heads and thinking about what to do next, or looking at Lin Xiao and Zhao Sheng, expecting them to point out the future direction.

At this moment, Lin Xiao and Zhao Sheng were staring at the calculation results on the computer, touching their chins, lost in thought.

Both of them have attainments in computational materials, so they prefer to use computational materials science to assist the synthesis method.

In this way, after thinking for a long time, Zhao Sheng suddenly said: "No matter how I look at it, I don't think this thing can exist. Speaking of which, Professor Lin, the structural model of your thing is calculated and simulated?"

He was still a little puzzled, how did Lin Xiao come up with such a thing, especially the model in front of him.

Lin Xiao didn't answer, but said: "Actually, I think, the focus is on the oxygen atom. The model of the oxygen atom losing electrons and gaining electrons still needs to be refined."

"Well... But if you think about it this way, the way the two combine is really weird."

"It feels like..." Lin Xiao paused for a while, and suddenly his eyes lit up: "Like being pressed hard?"

"Well...the description is indeed somewhat similar." Zhao Sheng nodded, frowning and said: "It feels like, originally, these atoms could not form chemical bonds, but because they were pressed, and then the attraction It overcomes the repulsive force and connects together!"

"Yes."

Lin Xiao's eyes lit up more and more, and after a long while, he suddenly said, "I'll go out first, you can take a look here."

"What's the matter?" Zhao Sheng couldn't help asking, didn't they all talk about the key point at this time?

However, Lin Xiao had already turned around and left the laboratory. Seeing this scene, Zhao Sheng had no choice but to give up and looked at the things on the computer again.

This thing, as expected, is the same as the original research on RDX pure silicon crystals, it is difficult to see the possibility of success at all.

Of course, the pressure that Lin Xiao just mentioned is very interesting.

……

Lin Xiao left the laboratory and came to his own office.

The reason why he wanted to leave the laboratory was because the thought about stress he brought up on the spur of the moment sparked inspiration in his mind.

In his model of the superconducting mechanism, although there is no statement about the pressure, there is a statement about the pressure of the electron binding in the superconducting state.

"It's like under the influence of pressure, electrons combine to form electron pairs, and then after the pressure is restored, due to the influence of other internal electromagnetic forces, these electron pairs will not lose their binding... This is equivalent to saying , the superconducting state is preserved!"

The more he thought about it, the brighter he thought, Lin Xiao estimated that the room-temperature superconductor that the system rewarded him was able to maintain superconductivity at room temperature because of this reason!

"This is equivalent to saying that when preparing this iron-based cuprate superconductor, if enough pressure can be applied, it is possible for the oxygen ions in the cuprate to continue to lose electrons and then combine with the iron-based material!"

Thinking of this, Lin Xiao suddenly felt as if he had found a way to prepare this room temperature superconductor.

"So... how much pressure is needed?"

For this problem, in addition to the calculation of the electronic topological bonding theory, the superconducting mechanism model is also used for calculation, which is why he did not stay in the laboratory. Now, the superconducting mechanism model is still the only one in the world. people master.

Without thinking too much, he started to calculate directly.

Almost without thinking, he wrote a lot of calculations, and in a short time, he got the answer.

"Do you need at least 23.3 atmospheres?"

Lin Xiao frowned. Compared with the pressure required to achieve superconductivity through high pressure, this atmospheric pressure is still relatively small. However, if it is really necessary to carry out production in this environment, the cost will rise steadily.

But in the end, he let go.

This is a room-temperature superconductor, so it doesn't matter if the cost is higher, as long as it is produced on a large scale, as the marginal cost continues to decrease, even if the cost is high at the beginning, it may reach a generally acceptable level in the end.

Thinking of this, he immediately got up, returned to the laboratory, and said to Zhao Sheng: "To make this thing, we need pressurized production."

"Pressure production?"

"Well, under a certain amount of pressure, I think these two things that wouldn't react before should react now."

Hearing what Lin Xiao said, Zhao Sheng recalled their speculation just now, and finally nodded: "I think, it is indeed possible."

"Ah."

……

After making a decision, they will naturally start building this high-pressure reactor next.

This question is not difficult, especially for men of science and engineering like them, their hands-on ability is very good.

Therefore, it took about ten days to order all kinds of materials and electronic components needed, and then it took about seven days to complete a slightly crude high-pressure reactor.
