The next day, when Liu Feng took his three apprentices to visit Du Bochao's materials laboratory, the news about electromagnetic ejection was still hotly discussed on the Internet.

As a senior military fan, Fei Xiujin has two panda eyes, while brushing the military forum, proudly breaking the news in the comments, but on the other hand, he is counting Liu Feng's lack of righteousness.

"Boss, when did you go to take a photo with the J-15 fighter, don't take me with you!"

"Boss, you're so boring!"

"Boss, you have to compensate me for my wounded heart. ”

"I heard from them that the J-15 fighter will continue to test for several days, please give me a chance to pretend to be forced!"

"Boss, boss, boss......"

However, it was definitely Liu Feng's eyes that answered this goods.

Is Lao Tzu just to take a picture with the J-15 carrier-based aircraft?

Lao Tzu is going to do research, hum!

As the deputy director of the 'Navy's Future Strategic Development Planning Department', how can the dignified Colonel Liu not have a good understanding of the Navy's weapons platform?

The J-15 carrier-based aircraft is just a coincidence.

Moreover, he didn't just take a picture with the J-15, he even ran into the cockpit to try it himself!

Forget it, don't talk about it, say it, this guy can't be envious and jealous to death.

He led the apprentices to exchange knowledge and experience in the field of materials science with Professor Du Bochao, and then urged these guys to practice in person, and after doing a few simple small experiments, Liu Feng's trip to the University of Marine Engineering came to an end.

In the following days, Liu Feng came to the Ningbo Institute of Materials of the Chinese Academy of Sciences, listened to Academician Cui's research report on superconducting materials at room temperature, and conducted experiments with Academician Cui to verify some problems.

Since he has studied several general computational materials, the successful development of superconducting materials at room temperature is only a matter of time, and since Academician Cui took over and led the entire Ningbo Institute of Materials, the research speed in this area is quite gratifying.

"Professor Liu, although we have not yet achieved the final room temperature superconductivity, we have recently discovered a very interesting phenomenon. ”

After Academician Cui handed Liu Feng a piece of information, he was very excited to introduce,

"After superimposing two layers of graphene and shifting the carbon atom pattern by an angle of 1.1°, we finally got a material with superconducting properties. Although the system still needs to be cooled to 1.7 degrees above absolute zero, the results suggest that it may conduct electricity like known high-temperature superconductors!"

"Subsequently, we filled in the missing part of the blueprint through a series of experimental activities, and finally proved that we can learn the mechanism of unconventional superconductivity such as lanthanum silicon-copper oxide superconductivity through graphene superconductivity!"

Speaking of which, graphene is a real panacea, it has always been a magical material, and it has even more surprising properties: this sheet material composed of a single layer of carbon atoms extending in a hexagonal shape is stronger than steel and conductive better than copper.

Scientists have studied graphene more thoroughly, and many related studies on graphene are focusing on how to prepare stable and high-quality graphene in large quantities, and it has also been found that when in contact with other materials, it shows superconductivity, but this behavior can be explained by conventional superconductivity, so it has not been paid attention to by scientists.

But Academician Cui is 'whimsical' and wants to use graphene to study unconventional superconductivity!

It's a 'madman' idea!

However, the results were very encouraging.

The so-called unconventional superconductivity phenomenon is a superconducting phenomenon summarized by Liu Feng.

Mainly refers to complex materials such as lanthanum silicon copper oxide, which can still conduct electricity at 133 degrees above absolute zero, but even with a general calculation program, the underlying mechanism of this lanthanum silicon copper oxide superconductor remains a mystery.

But in fact, the superconductivity of this lanthanum-silicon-copper oxide has always seemed simple, but it is difficult to understand and calculate correctly!

As a result, Academician Cui, who intuitively contains a big secret here, has found a unique way to develop an unconventional superconducting mechanism for learning lanthanum silicon-copper oxide superconductivity through graphene superconductivity.

He really deserves to be an academician-level boss!

The accuracy of scientific research intuition and the unbridled imagination of thinking made him, a person who has opened a hanging, have to bow down.

"We compared the relationship between the transition temperature and the carrier concentration in the superconducting state of the spin bilayer graphene, and found that the superconducting pairing strength in the spin bilayer graphene is even greater than that of unconventional superconductors such as lanthanum silicon-copper oxide and heavy fermions, and is closer to the BEC-BCS transition line. So, even if its superconductivity mechanism is not exactly the same as that of lanthanum silicon-copper oxide, it also establishes a new theory for why such a strong superconducting pair exists in such a seemingly simple graphene system. ”

Talking about this new discovery, Academician Cui was ecstatic,

"In the end, the hard work paid off, and we completely unraveled the relationship between the graphene system and the superconductivity of lanthanum-silicon-copper oxide! Thanks to this, we have developed a new superconducting material - very unique, very interesting, and very close to room temperature superconductivity!"

"Oh?" Liu Feng was also intrigued, "What is the material?"

"Weyl semimetal-niobium arsenide nanoribbons!" Academician Cui's eyebrows fluttered, and he handed Liu Feng another piece of information, "This is the Weyl semi-metal material with the highest electrical conductivity in the two-dimensional system known so far-niobium arsenide nanoribbons! Its electrical conductivity is 100 times that of copper thin films and 1,000 times that of graphene! It can be applied at tens of degrees below zero or ultra-low temperatures, and it still has a certain effect even at room temperature." ”

"We used three elements, niobium chloride, arsenic and hydrogen, and put them together for a chemical reaction to make this niobium arsenide nanoribbon, so the material allows electrons to pass quickly on the surface, so to speak, we have created a green channel, so that we can let the electrons pass through quickly and reduce energy consumption. ”

Liu Feng nodded.

Although he does not know much about Weyl semi-metal-niobium arsenide nanoribbons, and the material still does not meet the conditions for superconductivity at room temperature, it is clear that this discovery also provides a new direction for materials science to find high-performance conductors, and even has great value in reducing the energy consumption of electronic devices.

The reason why materials science is a basic discipline is because in the process of studying the target material, it is very likely to get some unexpected gains, although these unexpected gains are far from the nature of the target material, but they can often play a significant role in other directions, and even far more valuable than the target material!

This is the case of the Weyl semimetal-niobium arsenide nanoribbon material researched by Academician Cui.

Liu Feng only took a few glances at the specific parameters of this material and understood its specific application value: On the one hand, it can be used to make new types of electronic equipment; electronic appliances made of this material can detect weak magnetic fields and infrared radiation, and can even detect distant targets, such as the activities of airplanes, submarines, and tanks, which can make correct judgments and provide a direct basis for military command, and can also provide highly sensitive information for air defense early warning.

On the other hand, in addition to its role in the military, this material also has very broad prospects in civilian use.

In fact, there are two main reasons why our mobile phones and computers generate heat: the heat of the transistor itself and the heat of the current, and now the new conductive materials can solve the problem of heat generation of current flowing through the wire, which plays a great role in this regard.

At the same time, you can also use this superconducting material to make computer parts and accessories, which can greatly reduce the volume of the computer, and the energy consumption is also significantly reduced, and even the data processor made of this superconducting material can make the computer obtain high-speed processing power, and its speed is 15 times the computing speed of the existing large-scale electronic computer!

With this material alone, the hundreds of millions of scientific research funds allocated by antimatter engineering to the Ningbo Institute of Materials Engineering have not been in vain at all.

"Academician Cui, you have worked hard!" Liu Feng nodded with satisfaction, "The effect of this material on the military's radar detector is immeasurable, I believe they will be very interested." By the way, do you have any contact with the military?"

Academician Cui shook his head: "No." After all, this material is part of the antimatter engineering project, and without your permission, we can't call the shots. ”

Liu Feng was even more satisfied.

No one will like people who eat inside and outside, and it is naturally impossible for Academician Cui to make such a low-level mistake.

Although they both serve the country, they and the military belong to two departments after all, and their brothers still have to settle accounts, and it is absolutely impossible to empty the white wolf from them, let alone take the initiative to be trapped.

This product is already thinking about exchanging benefits from the military with this superconducting material: money? No, no, no, not to mention that there is no shortage of money for antimatter projects at all, and the army's 'poor ~ forced' will not be able to come up with much money!

So, what should I change for?

When I think of the bunch of professional and technical experts in the Naval University of Engineering, this product is full of gluttony......

In the following days, in addition to telling Academician Cui to make persistent efforts to develop the superconducting electromagnetic stone material of the super collider as soon as possible, Liu Feng, who couldn't help but be curious, also made a detailed test of the specific parameters of this new material.

The result naturally made Professor Liu very satisfied, so he directly took this material and ran to the Naval University of Engineering.

I went directly to the door to find President Lian Hanfei, because this President Lian is the dean of the School of Electrical and Information Engineering of Marine University of Technology!

The School of Electrical and Information Engineering is a star college under the University of Marine Engineering, not much worse than Academician Ma's School of Electrical Engineering, and there are three major majors in electrical engineering and automation, radar engineering, and navigation engineering.

"What, is there really such a material?"

It can detect the 'weak' magnetic field and infrared radiation, and even detect 'distant' targets, and even underwater submarines can't escape detection, so good?

"Quick, show me the parameters!"

Excited and puzzled, Principal Lian couldn't wait to get the parameters of this new material from Liu Feng's hands.

"No!" Liu Feng hugged the folder in his arms, as if he was protecting the mother of the calf, lest the traffickers snatch the child, "You must promise me a condition." ”

Principal Lian took a deep breath, calmed down the urge to slap this guy to death, and said helplessly: "What conditions?"

Showing the triumphant smile of the little fox, Liu Feng: "I want to borrow a few people from you." ”

"Borrow someone's hand?" Lian Hanfei stared at Liu Feng suspiciously, "Aren't you engaged in antimatter? Our electrical and information engineering are all engaged in communication equipment research, what is the use of you borrowing it?"

Liu Feng smiled, he only needs people who are engaged in these aspects of research: "You don't care, I have my own great use." ”

"No, you don't even say what you're going to do, what am I going to do to convince those people?" even the headmaster's head shook like a rattle.

"Well, anyway, you know about antimatter engineering, so I might as well tell you first. Liu Feng looked at Principal Lian meaningfully, thinking that since we already know about the antimatter project, we may even swallow Principal Lian in the future!

Leaned into your ear and whispered softly.

"What?" President Lian was very puzzled, "You should directly invite Professor Peng Chengzhi of USTC for this kind of thing, or simply report it directly to the state, and then rely on the power of the state to organize research, how can you ......?"

Liu Feng shook his head: "Professor Peng's side is an independent research department, so it is impossible to follow my arrangement, and, so far, this is just my conjecture, and I must find someone to verify it first." ”

Principal Lian raised his eyebrows: "And then you found me?"

Liu Feng pretended to be helpless: "Didn't this happen to catch up? Besides, this is a transaction, a transaction!"

Lian Hanfei stroked his chin with his hand, sighed and said, "But, it's a bit difficult to do......"

Liu Feng pouted: "Then forget it, if it really doesn't work, let's go to the Air Force, I believe people will be very interested." ”

"Don't, don't!"

After all, people are swordsmen and I am fish and meat, although I knew that this guy was deliberately bargaining, but even the principal still planned to pinch his nose and admit it, rolled his eyes and said,

"Tell me, how many people do you want?"

The corners of Liu Feng's mouth hooked up a smile of victory: "Actually, it's not much, a small team is enough." ”

Even the principal nodded, he was still sure of a small team.

Stretched out his hand: "Since it's a deal, then you have to let me see if your material is worth a team, right?"

"Give ......" Liu Feng very generously handed the information to Principal Lian.

After a while, he browsed through the information handed over by Liu Feng in detail, only to see that even Hanfei's hands were a little trembling, and after taking a deep breath, he stared at Liu Feng with a complicated expression - why couldn't their school develop this material?

Shaking his head, he said with a serious face: "Who else has seen this superconducting material except you?"

"What do you say?" Liu Feng patted his sleeve lightly and said easily, "As soon as I got the data of this material, I contacted you directly." ”

"Okay, very good!" Even the principal breathed a sigh of relief, and it was not in vain that he took the initiative to come up and make friends with Liu Fengpan before, this Professor Liu can always give people unexpected surprises!

You must know that they are not the only unit in the field of radar research, and even in terms of strength, there is CLP 14, known as the first radar institute and the largest in Asia!

There are also CLP 29 electronic countermeasures, CLP 38 radar machine institute, 23 institutes of the Second Aerospace Academy, and so on.

The above is known as the four major radar institutes of Huaguo!

Although their offshore engineering university is strong, it is still a step worse than the above four units.

Moreover, in addition to these units, there are also dozens of units such as CLP 10 Shuchuan, 22 Qingdao Tianbo Radar, 27 Zhengzhou, AVIC 607 Wuxi, 615 Qingdao, CSSC 723 Jinling, 724 Yangzhou, Chang'an Ordnance Industry Group and so on.

It can be said that they are engaged in radar, and the competition is very fierce!

Once they have this superconducting material, it is very likely that they will be alone in the radar field!

Said gratefully: "Professor Liu, I owe you a favor for this matter. ”

Liu Feng smiled, our favor is not so good.

"So, a pleasure to work with?"

"Happy ...... cooperation"
