The night is low and the stars are shining brightly.
A night flight pierced the night sky, sailing quietly and firmly towards the dimly lit imperial capital. Everything outside the window was completely silent, with only the occasional flash of city lights, like a distant lighthouse, guiding the way home.
As the plane slowly descended and passed through the thin clouds, the outline of the imperial city gradually became clear in the night.
"Chief, the plane is about to descend."
The accompanying secretary reminded softly.
Wang Shan said "hmm" with his eyes closed. In the three hours after boarding the plane, he actually didn't sleep.
It's not that he doesn't want to sleep, but that he doesn't dare to sleep at all. His right hand is holding the transparent plastic bag tightly and he doesn't dare to loosen it at all.
-
96 low-temperature superconducting material...
He didn’t even expect that what Chen Xing was going to give him was a low-temperature superconducting material, and said that it could be realized Room temperature superconductivity.
What are room temperature superconducting materials?
To put it simply, it is a material that maintains superconducting properties at room temperature.
Currently, materials with superconducting properties, such as niobium, NbZr alloy, and NbTi alloy, require ultra-low temperature environments to exhibit superconducting properties, and are not very practical.
But if room-temperature superconductivity is achieved, generally speaking, mobile phones will not generate heat when charging, because there is no energy leakage, and there is no conversion of electrical energy into heat energy.
Let’s put it this way, as long as room-temperature superconducting materials are successfully developed, everything from maglev trains and polymerization to Dyson spheres and interstellar travel may become a reality.
-
Although 96 degrees is still far away from normal temperature, it is the superconducting material closest to normal temperature known to modern science.
Because of this, Wang Shan did not dare to sleep, and could not sleep. He was afraid that he would lose this piece of low-temperature superconducting material when he fell asleep.
As the plane landed smoothly at the Capital International Airport, secretary and guard Rong Zhengjun reminded again: "Chief, we have arrived in the imperial capital. Are we going back to the compound now?"
"No."
Wang Shan shook his head, unbuckled his seat belt and said, "I have to go to the Dragon Academy of Sciences first. You call Qin Long and tell him that Wang Shan is visiting late at night and ask him to forgive me."
"Okay, chief."
Rong Zhengjun quickly took out his mobile phone. Because he was Wang Shan's secretary, he basically had all the contacts in Wang Shan's mobile phone address book.
“Beep——”
After several busy tones, the call was connected.
"Hello, Chief, Dean Qin has just gone to bed. Do you have any instructions?"
As we all know, when one reaches a certain position, there will be a secretary around him, responsible for answering phone calls and processing documents.
At certain times, the secretary can even represent the principal.
"Hello comrade, please tell Dean Qin that Wang Shan is coming to the Academy of Dragon Science and has something to discuss."
"Understood."
< br>
After the secretaries on both sides connected, Rong Zhengjun also put down his mobile phone and quickly followed Wang Shan's steps to get off the plane, then walked through the empty arrivals hall. When he walked out of the airport, there were already three Red Flag cars waiting on the road.
Wang Shan looked at Chiqi Car thoughtfully, looked sideways at Rong Zhengjun and said: "In the future, my distribution car will be changed to pilot car. To support the development of new energy vehicles, we must not fall behind again."
Because the Dragon Kingdom was hundreds of years behind in industrialization, its modern history has been extremely humiliating. Now that it has finally improved, it must support its development.
This is just like the fact that a college student finally appeared in the village. Regardless of whether he has a bachelor's degree or a junior college degree, everyone has to raise money for him to study.
This is the case with Liu Dongzi. The whole village raised money for him to go to college, and he lived up to expectations. Relying on Wang Dong Company, he became a well-known rich man. Nowadays, his village distributes large sums of money during holidays.
“I understand.”
Rong Zhengjun nodded.
A biting night wind blew towards his face. Wang Shan felt the temperature on his face drop sharply. He did not continue to stroll around and got directly into the red flag car in the middle.
……
And on the other side.
The apartment area of Longke Academy.
After receiving the call, Qin Long's secretary Yan Tinghao hesitated for a few seconds, walked out of his room resolutely, came to Qin Long's door, and knocked three times with courage.
A few seconds passed, but there was no response from the room.
Yan Tinghao knew very well that Qin Long had just slept for less than an hour. Two hours ago, he was still improving the structure of nanomaterials in the laboratory, trying to find a new balance point.
You may not even know it’s thundering, let alone knocking on the door after just one hour of sleep.
"Dean."
"Dong dong dong——"
Yan Tinghao increased his intensity and shouted again, and finally there was a reaction in the room.
"What's wrong?"
The voice was tired and confused.
Qin Long had specifically told him that he had an academic conference to attend tomorrow and there was nothing particularly urgent, so he should not disturb his rest.
"Dean, the secretary of Chief Wang Shan just called and said that Chief Wang Shan is coming and has something important to discuss with you."
Yan Tinghao quickly told the story.
"It's already this hour, and the old chief still comes to see me. The matter must be particularly important." Qin Long didn't dare to delay, quickly dressed up, then opened the door and walked to the living room.
"Make me a pot of tea, make it stronger."
"Okay."
Yan Tinghao quickly followed suit.
After a short wait, a pot of strong tea with fragrant aroma will be brewed.
Qin Long picked up the tea. He could only drink the scalding hot tea cautiously. In the process, his brain gradually became clearer.
When the pot of tea was completely drunk, Qin Long continued: "This time, make a pot of tea with normal concentration to entertain the old chief."
"I understand."
Yan Tinghao still did as he was told.
After the second pot of tea was brewed, Yan Tinghao's cell phone rang in his pocket. He quickly took it out. After seeing the caller ID name clearly, he looked at Qin Long and said, "It's the secretary of Chief Wang Shan."< br>
"They should have arrived, Xiaohao, go pick them up." Qin Long said in a deep voice.
“Okay.”
Yan Tinghao answered the phone as he walked out.
In the past ten minutes or so, footsteps were heard outside the door of the apartment building. The moment Wang Shan walked in, Qin Long quickly stood up and said: "The old chief is driving late at night, please come in quickly."
< br>"It's not that I want to disturb your dream, Dean Qin, but there is really no way. If this matter doesn't come to a conclusion, I won't be able to sleep all day." Wang Shan walked into the living room with a troubled face.
“What is it?”
Qin Long’s heart contracted violently.
He was a little confused. He didn't understand what could actually affect a top boss like Wang Shan. What kind of explosive content was this?
"You can go out first." Wang Shan did not rush to talk, but looked at Yan Tinghao and Rong Zhengjun and gave the order to expel the guests.
"Okay, old chief."
"Copy that."
The two exited the apartment and closed the door.
Wang Shan's move aroused Qin Long's interest. Seeing the door to the apartment being closed, he quickly asked: "What is it? It makes you so nervous."
" Don't be nervous, this is about room temperature superconducting materials."
As soon as Wang Shan finished speaking, Qin Long's hand trembled suddenly, and his pupils flickered. It was incredible, even the expression management was out of control.
“Normal temperature superconducting materials?”
"You said it's a material that exhibits superconducting properties at room temperature?"
He had tried very hard to restrain himself, but his body still couldn't help but tremble due to excitement, and his heart was already in turmoil.
"Yes, but it has not been fully realized yet. According to the material Chen Xing gave me, it only needs -96 degrees to exhibit superconducting properties." Wang Shan sat down on the sofa and held the The low-temperature superconducting material was placed on the table for nearly four hours.
"Chen Xing?"
Qin Long was stunned and asked: "Is this what Chen Xing gave you?"
"Yes, he asked me to transfer it to You also asked us to help you." Wang Shan did not ask Qin Long for help, but used the word "we".
“I really underestimated Chen Xing and Longxing Group. I didn’t expect that they were not only involved in fast charging technology, energy storage, information networks, and semiconductor chips, but they even had a presence in the field of superconducting. This is simply unbelievable.”
Qin Long swallowed.
“I didn’t expect Longxing Group to have such a deep layout. This far exceeded everyone’s expectations. But then again, this material has not been proven to have superconducting properties. I don’t know, Dean Qin. If you have time, let’s test it so that my hanging heart can settle down.”
Wang Shan visited Qin Long overnight. In addition to delivering the message for Chen Xing, he also wanted to see with his own eyes whether this was the case. superconducting materials.
If it is a material with superconducting properties, then the technological foundation of the Dragon Kingdom will be much stronger. The day it completely explodes will be the day it returns to the "Celestial Kingdom".
“That’s what I meant.” Qin Long picked up the transparent sealed bag and expressed his thoughts.
The two hit it off immediately, and walked straight out the door without caring about the newly brewed tea.
When the door opened, Yan Tinghao and Rong Zhengjun were stunned for half a second. They only talked for less than two minutes. Is this the end?
Is something that can be discussed in two minutes worth Wang Shan’s late night trip and Qin Long’s getting up late at night to receive it?
The two of them don’t understand.
Just when they were about to speak, Wang Shan waved his hand and said, "Just stay here, Dean Qin and I will go back."
"Yes, we are very Come back soon."
Qin Long agreed.
Because inside the Dragon Academy, they are not worried about any danger. After all, the sentries on guard are armed with live ammunition and have the privilege of shooting. No one is stupid enough to break in.
Even if someone sneaks in secretly, they must be able to sneak in. You must know that the security level of the Dragon Academy is the highest level in the world. Even a fly cannot fly within half a meter as long as it is ordered not to enter.
Looking at the backs of Qin Long and Wang Shan leaving, Yan Tinghao and Rong Zhengjun looked at each other and chose to obey the order.
But as soon as the two of them left, Yan Tinghao couldn't help but ask: "Secretary Rong, what is it that makes things so mysterious? Is there some new technology?"
Being in the same circle of secretaries, they are no strangers and visit each other during holidays.
"To be honest, I don't know. I only know that the chief and Chen Xingxiao got together for a while, and then the chief's expression changed."
"What changed?"
Before Rong Zhengjun finished speaking, Yan Tinghao couldn't help but ask.
“Nervous, even panicked.”
“Panic?”
“Yes, panicked.”
Rong Zhengjun nodded and recalled the scene at that time: "This is the first time I have seen a panicked look in my more than ten years as secretary to the chief minister. Even during the economic crisis in 2008, he never showed such a look."
"..."
Yan Tinghao was completely shocked.
He also did not expect that Wang Shan and Chen Xing would look panicked after talking. What on earth did they say between them?
The economic crisis in 2008 was not as shocking as a conversation with Chen Xing. Yan Tinghao took a deep breath and said in a deep voice: "I feel that this matter is not trivial. It is better that we talk less about it today. It's better to keep things in the stomach late, and no one can say anything about it."
"That's natural."
Rong Zhengjun agreed.
Although they didn’t know exactly what Chen Xing said to Wang Shan, the fact that he could make Wang Shan rush to the Academy of Dragon Science without stopping and wake up Qin Long already showed the seriousness of the matter. As secretaries, the two of them also knew what to say and what not to say.
……
Materials Research Institute.
While Yan Tinghao and Rong Zhengjun were thinking deeply, Wang Shan and Qin Long had already arrived at the laboratory building of the Institute of Materials and called Zhang Zhongchun, an academician who specializes in room temperature superconducting materials.
"Long time no see, old chief. Are you feeling well?" Zhang Zhongchun greeted Wang Shan warmly with a smile in his eyes.
"You are still strong. Let's talk about old times later. Let's get down to business first."
As soon as Wang Shan finished speaking, Zhang Zhongchun also knew how to watch people's words and quickly echoed: "Yes, yes, you guys What do you want from me?”
“Test some materials”
Qin Long spread his hands.
“What is this?” Zhang Zhongchun’s eyes widened but he didn’t know why. The structure of such small pieces of black coal could not be seen with the naked eye.
"Are you mentally prepared?" Qin Long first gave him a vaccination.
Superconducting materials may be something that changes the world for others, but for people in related fields, it is a lifelong dream.
This is like Fan Jin, who passed the national examinations and failed repeatedly in the exams. He was over fifty and suddenly became a successful candidate in high school. His long-standing wish came true. It is reasonable for him to be so excited that he goes crazy.
Zhang Zhongchun is one of the few academicians in the field of superconducting materials. Qin Long had to be cautious just in case.
“Huh——”
“Say it.”
Zhang Zhongchun took a deep breath and made enough mental preparations.
"Low temperature superconducting materials can have superconducting properties at -96 degrees Celsius."
"What???"
"Super..."
When Zhang Zhongchun finished speaking, Qin Long covered his mouth and said, "Keep your voice down. The less people know about this, the better. Any research needs to be conducted in secret. Do you understand?"
Zhang Zhongchun nodded.
Qin Long let go of his hand, but Zhang Zhongchun's heart still stirred up waves. He had no idea that he would be unable to find anything after breaking through the iron shoes. It took no effort to obtain the low-temperature superconducting material.
-
Low-temperature superconducting materials at more than 200 degrees Celsius may not be of much use, but there is room for application at -96 degrees Celsius, such as in the field of space exploration.
“You came to me so late, you shouldn’t just talk about this matter, right?”
Zhang Zhongchun glanced at the two of them.
"There is indeed one more thing." Wang Shan nodded and continued in a deep voice: "Now we are not sure whether this material has superconducting properties. We also ask Academician Zhang to come to the instrument for testing."
“Not sure?”
Zhang Zhongchun was confused.
Is your happiness in vain just thinking about him?
He thought Qin Long had someone test it, or that it was the work of an academician, but he didn't expect it to be a three-no product.
"Not sure."
Wang Shan nodded again.
"Harmful." Zhang Zhongchun smiled helplessly and moved his steps: "Then follow me. It's easy to test, just use liquid nitrogen to cool down."
"Old Chief, please .”
Qin Long made a first gesture.
Enter the laboratory building, they took the elevator to the negative floor, walked several hundred meters along the corridor, passed several verifications, and finally arrived at Zhang Zhongchun’s superconducting materials laboratory.
"Then I tested it directly?"
Zhang Zhongchun asked.
"Well, please." Wang Shan nodded, his eyes full of expectation.
Qin Long quickly handed over the materials.
Zhang Zhongchun took the transparent sealed bag, first went to the storage area to get a pack of brand new experimental cube magnets, and then came to the experimental bench.
I saw him opening the package, taking out the magnets and laying them on the experimental bench. Then he opened the transparent sealed bag, clamped the superconducting material with tweezers, and placed it on the magnet block.
After doing all this, he looked at Wang Shan and Qin Long and said: "I will use liquid nitrogen to cool it now. If there is no diamagnetism, it means it is not a superconducting material."
Whether it is a normal temperature superconducting material, a low temperature superconducting material, or a high temperature superconducting material, it is diamagnetic.
If it does not have diamagnetism and achieves zero resistance, it is a new type of superconducting material, which is beyond the cognitive scope of modern science.
“Well, pay attention to safety.”
Wang Shan reminded.
"Do you want my help?" Qin Long asked, liquid nitrogen is a dangerous job, and if the operation is incorrect, life may be injured.
“No, just watch.”
Zhang Zhongchun smiled lightly. He came to the liquid nitrogen storage tank, took off the nitrogen long-neck scoop, and opened it without taking any protective measures. I took a quick scoop from the mouth of the jar.
Don't think he doesn't take safety seriously. When operating liquid nitrogen, it is safer to operate with bare hands than with gloves.
This is because even if liquid nitrogen accidentally drips onto the skin, according to the Leidenfrost effect, when a liquid with an extremely low boiling point encounters skin that is much higher than its boiling point, it will quickly boil and produce a layer of The insulating layer of gaseous nitrogen and bounce other liquid nitrogen droplets away.
If you wear gloves, it is not as safe as bare hands.
Of course.
The premise is not to touch a large amount of liquid nitrogen.
If you try to die by putting your hand into the liquid nitrogen tank, let alone the Leidenfrost effect, it will be useless even if Ultraman comes.
After scooping a ladle of liquid nitrogen, Zhang Zhongchun carefully walked back to the experimental platform, and then slowly poured it into the low-temperature superconducting material.
1 second.
3 seconds.
5 seconds.
In about 10 seconds, the fingernail-sized piece of low-temperature superconducting material finally reacted and began to float above the magnet.
“Is it really diamagnetic?”
Zhang Zhongchun was overjoyed.
Both Wang Shan and Qin Long held their breath, waiting for Zhang Zhongchun's further confirmation.
“With diamagnetism, it has the first element of a superconducting material. Let’s lower its temperature to avoid being affected by room temperature.”
Zhang Zhongchun said Do it as you go.
After another ten seconds or so, he began to prepare tools and use the four-probe test method to measure the resistance value of the material.
The so-called four-probe test method is to use four probes to pass current through the sample, measure the voltage at both ends of the sample, and then calculate the resistance value through the resistance formula R=U/I.
“It’s really zero!”
After completing the operation, Zhang Zhongchun couldn’t help but exclaimed.
"Look at the current temperature."
Qin Long reminded.
Zhang Zhongchun picked up the low-temperature detection gun and saw -174 degrees written on it. He also explained truthfully: "-174 degrees has superconducting properties. This is indeed a new low-temperature superconducting material."
"Wait a minute."
Qin Long wanted to know whether -96 degrees is zero resistance. If it is really zero resistance, then Chen Xing's Longxing Group's foundation is a bit too strong. There are even low-temperature superconducting materials.
Due to the influence of room temperature, the temperature of low-temperature superconducting materials continues to rise.
-
151-
133-
111
"Hurry up and test again."
"Okay!"
Zhang Zhongchun continued the test, and the final result was still zero resistance.
"It's really a low-temperature superconducting material at -96 degrees. Old chief, Dean Qin, where did you get the material from?"
Zhang Zhongchun was puzzled.
Qin Long looked at Wang Shan, he didn’t know too many inside stories.
Wang Shan: "Chen Xing gave it to me."
"Chen Xing? Which Chen Xing? Does our Academy of Dragon Science have such a person?"
No, Zhang Zhongchun untie.
Most academicians spend their entire lives in laboratories and have no contact with outside information. It is normal for them not to know Chen Xing.
This is just like the training of some special forces. They need to be isolated from the outside world for one to three years so that the soldiers can fully adapt to the original environment and cope with sudden battles. Not to mention that they don’t know Chen Xing, even if Lao Mi replaces him in the election, they will Won't know.
"The CEO of Longxing Group." Wang Shan reminded again.
“It turned out to be him.” Zhang Zhongchun suddenly realized it and remembered it. He said with surprise: “I heard Academician Qu Cheng mention it last time. I didn’t expect that Longxing Group is not only deeply engaged in semiconductor chips, but also involved in super... "What is the value of this material?"
Wang Shan asked.
“You can’t buy it for a thousand pieces of gold.” Zhang Zhongchun gave his evaluation and pointed out its scope of application: “-96 degrees can already be used in special fields, such as space exploration equipment. The low temperature on the back can be fully activated. Superconducting properties. "
"-96 degrees, it can also be used in some special areas or special laboratories." Qin Long looked at Wang Shandao.
Both of them had excitement in their eyes, and their emotions were a little excited. You must know that this is a witness to another breakthrough in human technology.
Seeing the expressions of the two people, Wang Shan also understood the value of low-temperature superconducting materials, and told Chen Xing’s conditions:
“In addition to using low-temperature superconducting materials, Chen He handed me the materials and asked me for one more thing, that is, he wanted to borrow experimental equipment from the Dragon Science Academy.”
"Borrow equipment?"
"You don't want to borrow superconducting materials, right?"
As soon as Zhang Zhongchun finished speaking, Wang Shan smiled and said: "Yes, that's what he thinks. He said that he would borrow the experimental equipment from the Dragon Academy to solve an urgent need and wait two months before returning the equipment."
Zhang Zhongchun: "..."
Qin Long. : "..."
Return the equipment?
Is it possible to return the loaned equipment?
Even if there is repayment, it will not be two months, at least two years, or even twenty years. What will the Academy of Dragon Science use then?
"This..."
Zhang Zhongchun hesitated for half a second, looked at Wang Shan and said: "Old chief, with a new breakthrough, I feel that our Dragon Science Academy can also explore in depth, there is no need Lend out the experimental equipment.”
"You also know that experimental equipment has always been our shortcoming. It took a lot of effort to get these together."
"I know, but he gave me Made a guarantee." Wang Shan's tone suddenly became serious, and he lowered his voice a little and continued: "He said that as long as there is a three-beam pulse laser deposition system, a vacuum smelting furnace, and a superconducting quantum interferometer..."
“Longxing Group is confident that it will turn room-temperature superconducting materials into a reality within one year. I thought of our Longxing Academy at that time and wanted to coordinate the experimental equipment.”
一Within a year, room temperature superconductivity will be achieved.
It is no exaggeration to say that Zhang Zhongchun and Qin Long have stopped breathing now, and even their hearts have stopped for half a second. This is really too confident!
Normal temperature superconductivity is achieved in one year, while others have been standing still for hundreds of years!
Wang Shan could see the dull expressions of the two people, but in fact, it was Wang Shan who took the initiative to coordinate the experimental equipment of Longxing Academy, and wanted to do his best to help Longxing Group.
As for Chen Xing’s request for help, it will take time to realize it slowly.
