You say you have an iron will, are you serious?

Chapter 366 Room temperature superconducting materials?

"It turns out to be a very conventional graphene material~ Just the material ratio and structure?"

Looking at the report, Zhao Mo felt strange at first. Because it was very ordinary, it really did not match the identity of the "mysterious fragment". This was rewarded by the system~

But soon, when he turned to the material ratio calculated by Zhao Bufan and the scanned structure, his face immediately showed a hint of interest.

In the three-dimensional image, you can see that this material has a very strange twisted structure, but it is very elegant, a bit like a curved corner formed by a donut.

Appearance represents strength, which is true in industry and academia.

Those with good looks are usually very powerful, such as the Veyron fighter jet and the 055 Daejeon.

This is actually the same as what Professor Qiu said yesterday about how it is possible for an elegant structure not to be recognized by nature.

"This material has excellent corrosion resistance, oxidation resistance and other properties, and is easy to process... Today I am going to test its electrical properties. I suspect that this special structure will perform very well in terms of electrical properties..."

While Zhao Mo was reading the information, Zhao Bufan also gave a brief introduction.

After listening to Zhao Bufan's words, Zhao Mo quickly expressed his approval and said with a smile: "Okay, I will test it with you today~"

Any material needs to be tested repeatedly during the development and production process. This is a necessary process, and it is also an extremely boring and time-consuming process.

After this mysterious fragment came down from outer space, its volume has not changed, and it has not changed due to changes in gravity.

Zhao Mo smiled, walked over and patted him on the shoulder.

At noon, when it was time to eat, Zhao Mo got up on time and prepared to eat.

Zhao Bufan said quickly, thinking that Zhao Mo had opinions about his work.

Half an hour later, Zhao Bufan, who was in the experiment, made his first surprised sound.

"This material has very good diamagnetic properties~"

Zhao Bufan was startled for a moment, then came to his senses and responded quickly: "Okay~"

So, under Zhao Mo's guidance, Zhao Bufan made a list of parameter conditions, and then started testing one by one according to this list.

Zhao Mo has been watching, and naturally he can see clearly that the tested diamagnetism has actually reached the negative fourth power of 10, which is similar to the diamagnetism of van der Waals crystals and ionic crystals, and one to two orders of magnitude stronger than metal substances. .

"I can handle it, so I won't bother you, right?"

Zhao Mo watched from the side, thinking of his own.

"With such strong diamagnetic properties, if you go up two more, you will reach Type II superconductor~"

Zhao Mo suddenly felt something in his heart and said, "Test a few more sets of performance data under different parameter conditions."

Zhao Bufan smiled sheepishly and said, "I'm used to it~"

"People are as good as steel. If you don't eat one meal, you will be hungry. Let's go, eat first, don't miss this little time~"

Zhao Mo also joined in and tested together.

When he turned around, he saw that Zhao Bufan was still working hard, and it seemed that he didn't intend to have lunch.

Zhao Mo was very surprised and at the same time confirmed his guess: "It seems that the missing part is unusual. Wudaokou's equipment cannot detect it~"

Zhao Mo patted his shoulder and said, "I happened to be fine today~"

Zhao Bufan stopped talking, then smiled, took the materials, and started further testing.

However, even though he said this, when Zhao Mo spoke, he immediately stood up and walked to the canteen with him.

The two were walking and chatting, and Zhao Mo asked about the "Yutu" battery: "How is the research and development going?"

Zhao Bufan smiled and replied: "It has passed the verification. I am going to transfer the current development work to Chief Engineer Zhang. Chief Engineer Zhang talked to me not long ago to start developing the Mars rover battery. It's just that you haven't come back, so I haven’t promised him yet.”

"Oh?"

Zhao Mo glanced at him in surprise, and then said happily: "You don't need to ask me about this, just agree. Come on, do your best."

Zhao Bufan nodded seriously: "Thank you, I know~"

With the successful development of the Long March 5 high-thrust rocket, the construction of manned moon landings and lunar bases has been advanced, and the work of Mars exploration and sample return has also been put on the agenda and must be advanced.

In fact, as early as 2004, the Mars exploration mission began its demonstration work, and the person in charge was Commander Zhang.

After Zhao Mo became deeply involved in aerospace work, he realized that the success of "Zhurong" did not happen suddenly, but after nearly two decades of research, it was a success.

It is often said that one minute on stage can take ten years off stage. The moment Zhurong landed on Mars, many astronauts, including Chief Engineer Zhang, had been working hard for nearly two decades. You can imagine how hard the work was.

How many twenty years are there in life?

There are only four in total. Many astronauts, including Commander Zhang, went straight from youth to old age!

Just for that moment!

Zhao Mo participated in the planning of this generation's manned moon landing and lunar base construction missions, but he did not participate in the planning of the Mars exploration plan. He only gave a suggestion to complete the detection and sample return in one go.

Of course, the country adopted this suggestion.

The reason why we just went for detection in the previous life was that in addition to immature technology, insufficient rocket capacity was the most important constraint. If the transportation capacity is insufficient, it will be impossible to launch large-mass spacecraft to the Earth-fire transfer orbit, which will limit the scope of the mission. Now that the transportation capacity is sufficient, we can directly launch large-mass spacecraft, including Mars probes, Mars sampling vehicles, return vehicles, etc., all of which can be packed in to complete multiple tasks at once.

Zhao Mo just didn't expect that Chief Zhang would also find Zhao Bufan for the Mars rover's battery.

This time, he was not involved.

After eating and taking a short rest to digest their food, Zhao Mo and Zhao Bufan returned to testing work.

After that, Zhao Bufan stayed in the laboratory for three consecutive days.

Because Zhao Mo has classes and other research work, he takes time to go into the laboratory to follow up personally when he has free time.

On the afternoon of the fourth day, when Zhao Mo returned to Wudaokou from the construction site of Beijing's fourth-generation synchrotron radiation light source and entered the laboratory, Zhao Bufan suddenly exclaimed.

"Fuck! Zero resistance, superconducting!"

Zhao Bufan's voice was full of shock, excitement, and uncontrollable joy.

"Superconducting?"

Zhao Mo looked shocked, and immediately quickened his pace, jogged to Zhao Bufan, and asked, "What's going on now?"

The excited Zhao Bufan was startled by the sudden sound, but when he turned around and saw it was him, an excited smile suddenly appeared on his face again. He grabbed his hand and said loudly: "Zhao Shen, this material is a superconductor. Ah, when the critical temperature is as high as -9°C, it approaches zero resistance and has a diamagnetic performance close to -1!"

While speaking, he even jumped up, which showed how excited he was.

"Let me take a look first~"

Zhao Mo is also very excited. A superconducting material with a critical temperature of -9°C is an unprecedented material. This material is not much different from a real room temperature superconductor.
-

9℃, which is undoubtedly much higher than the negative one or two hundred degrees required for the most cutting-edge materials in the field of superconducting material research.

If this material were released, it would undoubtedly cause a storm, shaking the whole world and even going crazy.

However, he still suppressed his excitement and calmly watched the test data and test video that Zhao Bufan had just recorded.

Sure enough, under normal pressure, once the temperature dropped to -9°C, the expanded mysterious fragments immediately showed zero resistance characteristics and completely antimagnetic characteristics, and were steadily suspended on the magnet, even if pressed by hand. Afterwards, it will levitate again the moment you release your hand.

Judging from the phenomenon, this material does indeed look like a superconducting material, but whether it is or not cannot be finalized.

So after getting excited, Zhao Mo quickly regained his composure and said in a deep voice: "Continue the test, and we will conduct experimental verification after the test is completed. It may not necessarily be a superconducting material, and there may be other impurities that affect the test results. "

As soon as he said this, although Zhao Bufan didn't believe that this behavior was not a superconducting material, he thought that he must have a reason for saying this, so he calmed down and started to continue testing.

Later, Zhao Mo and Zhao Bufan personally tested the characteristics below the critical temperature of -9°C on site.

Seeing the resistance of the material plummeting from a very high level until it approached zero, Zhao Mo couldn't help but take a deep breath. It was indeed very possible.

After getting off work in the afternoon, Zhao Mo returned to his office with the test data of the past few days and the report made by Zhao Bufan on the first day.

He began to conduct in-depth research on this material, combined with the results of experiments done in space.

He had a hunch that this "mysterious fragment" contained huge secrets. It was not just a simple superconducting material, but might also contain deeper mysteries. It was not ruled out that the solution to the Yang-Mills equation was contained in it.

Since the discovery of superconductivity in 1911, no real superconducting mechanism has been studied, that is, no real theory has been formed to guide it.

The BCS theory, which won the Nobel Prize in Physics in 1972, is a superconducting theory based on electron-phonon coupling interaction. It cannot explain the microscopic mechanism of unconventional superconductors, and this theory gave birth to a theory proposer, MacMillan. The named "McClelland limit" states that the critical temperature of a superconductor will not be higher than 40K.

40K, which is -233.15℃.

In fact, in 1987 after the BCS theory, the critical temperature exceeded 40K and reached 93K, achieving the superconducting critical temperature in the liquid nitrogen temperature region.

Of course, this does not mean that the BCS theory is not worthy of the Nobel Prize. After all, although this theory is not comprehensive, it also reveals part of the mechanism of superconductivity. Later, the GL theory, which won the Nobel Prize in Physics in 2003, proposed the concept of surface energy K and established the physical basis of type II superconductors. It is a phenomenological superconducting theory and a small supplement to the BCS theory.

As for high-temperature superconductivity, the theory is even less clear.

The so-called high temperature is relative to the low temperature in physics, which is actually more than minus 100 degrees.

"Concepts really kill people. Minus one hundred degrees is also a high temperature, and the mysterious fragment's minus 9℃ is an ultra-high temperature... At high temperatures, particles move faster and move irregularly. The temperature rises even more, and the resistance also increases, so , is this the reason why the structure of the mysterious fragments is very special?”

Zhao Mo drew casually, and a twisted crystal structure appeared on the manuscript paper, with corresponding expression numbers and formulas constantly appearing on the edge~
