International students returning to 90

The scientific research circle in the United States is so big, Zhuang Cheng quickly got the information he wanted.

"Zhuang, you have to admit that there are really geniuses in this world." Nick was amazed when he handed him the information.

"During my master's degree in physics, I explained the new application of 'Topological Theory', which was put on the cover page of Science at that time. Zhuang, do you remember how long you worked hard to get this treatment? Five papers, a total of five papers The accumulation of papers!"

"Professor Horn has publicly stated more than once that after Master Lin's graduation, he will be invited to join his current research. Professor Horn's current project is locked in the Nobel Prize. What a temptation to participate in the Nobel Prize project. , He actually refused." Nick was amazed.

"A gifted idealist, proud and clean-spirited. Zhuang, this is not an easy person to get along with."

Zhuangcheng and Nick are old friends. When Zhuangcheng first came to the United States, his host family was Nick's.Now that the two are working together at Stanford, the relationship is naturally good.

"Proud, clean eyes..." Zhuang Cheng repeated these two words in a low voice, and Lin Yi's words, "You are really a scholar I respect very much", couldn't help being dumbfounded.

"How is your cooperative laboratory finding? To be honest, Zhuang, your requirements are too high. Theory is theory, practice is practice. There are many theories in physics, but how many can be applied to practice. I suggest you Take your time, as long as your theory can be proven, there will always be a practical application."

Nick half leaned on the table, looking at his Chinese friend.Many people say that Zhuang Cheng is a genius, but as a friend, Nick clearly sees how Zhuang Cheng got to this point.

The lights in Zhuangcheng's study room never went out before twelve o'clock, and the books he flipped through were always filled with dense notes, over and over again, and he hardly had time for rest and entertainment. In Nick's impression, Zhuangcheng was always They are all meticulous, either in the laboratory or on the way to the laboratory.

God will never forget a hardworking person, as much as he puts in, he will reap as much. Nick thinks that Zhuangcheng is the best example of this sentence.

"Nick, thank you." Zhuang Cheng naturally understands Nick's kindness. The success of the theoretical prediction can bring him enough glory, but this is not his original intention to engage in physics research.

He wants to do something for his country, not just in theory, but something that can actually benefit one billion compatriots. Maybe some people will think that he is overconfident, but the education Zhuangcheng has received since he was a child That's it.

Nick sighed, his friend is good at everything, but he is too stubborn, just like the ancient oriental country described by the American media, conservative and stubborn.

When he walked to the door, he suddenly seemed to remember something, turned his head and said, "Zhuang, if you really want to create miracles, maybe Lin Yi would be a good choice." After stacking the documents, he waved his hand and turned to leave.

As of this evening, thirteen new material laboratories, large and small, have contacted Zhuangcheng and expressed their desire to cooperate.Screening out those small laboratories that are just for luck, there are six remaining, and Lin Yi's new energy center is barely among the six.

But except for Lin Yi's lab, all the labs' promises are willing to realize Zhuang Cheng's prophecy, not practice it.Just one word difference, but the meaning is very different.

The experimental designs given by other laboratories are all limited to the laboratory. Only Lin Yi's experimental design combines the actual situation of the current power grid in the United States. He really wants to put his theory into practice.

Zhuang Cheng contemplated Lin Yi's experimental design for a long time, and finally put it down silently, picked up the experiments from other laboratories and looked at them.

As Nick said, Zhuangcheng has an extremely conservative side in his temperament, and he is a person who will not be impulsive.

On the other hand, Lin Yi has never been a person who sits and waits for death. If the mountain does not come, I will go to the mountain. There is no news from Professor Zhuang for two days. Carried away.

If Lin Yi’s friends in his previous life heard about his mental activities, they would definitely say, hey, I also “disdain” your experimental design. Others have blind eyes, and Professor Zhuang has become prudent and cautious. The filter is thick enough.

"Researcher Lin, everything has been brought up." He Qun wiped the sweat from his brow, and put the two large boxes in his hand on the table in front of Lin Yi.

"What about barium lanthanum copper oxide?"

"Here. Researcher Bryce has processed it. The vial in the box is liquid nitrogen for cooling."

A day ago, Lin Yi suddenly gave him a list and asked him to go back to Berkeley to prepare materials.

Because of the stimulus of one hundred thousand dollars, He Qun has been very motivated these days, wishing to show his loyalty to Lin Yi, so he drove back to Berkeley without even asking. Tidy things up.

"Well done." Lin Yi praised him in a rare way. He Qun felt great satisfaction when he heard that, as if there were countless pink bubbles flying in front of his eyes. He called this feeling happiness.

Lin Yi's idea is very simple. As a scholar, he understands Zhuang Cheng's concerns very well. Zhuang Cheng cherishes his experimental results and tries his best to minimize the chance of experimental failure. The blueprint on Lin Yi's paper may make his heart move , but definitely not enough to make a person accustomed to conservatives choose to take risks.

After all, even with the big banner of Simpson, Lin Yi's new energy center is indeed just an empty shelf right now.

Lin Yi can't change the status quo of the new energy center overnight. What he can do is to prove to Zhuangcheng that his blueprint is not just on paper.

In January 1986, Bernoz and Müller, scientists at the International Business Machines Laboratory in Zurich, Switzerland, first discovered that barium lanthanum copper oxide was a high-temperature superconductor. In the second year, almost all new material laboratories around the world participated in the superconductor. In the development of guiding technology.

Theoretically, high-temperature superconducting technology has been able to be applied on a large scale, but it has not been promoted due to limitations of the current industrial level, cost and other factors.

And Zhuangcheng's high-temperature superconducting theory focuses on practice, that is, the application on high-temperature superconducting cables-DC superconducting cables.

What Lin Yi wants to do now is to make a simple superconducting cable and realize electricity in a liquid nitrogen tank.

A complete cable system should include DC cable energized conductors, refrigeration systems, terminals, and online monitoring systems. Lin Yi's current experimental conditions are poor, and the initial thing he can do is DC superconducting cables.

He had participated in the superconducting cable design of the State Grid in his previous life, and he knew the structure of the superconducting cable very well, including the stainless steel bellows skeleton, insulator, five layers of electric conductor layers, and a set of cryogenic containers.

Because only a small-scale feasibility experiment is planned, the low-temperature container can be replaced by a simple processed liquid nitrogen tank, and the stainless steel bellows skeleton, Lin Yi has asked Tony to carry out simple processing.

The insulator is divided into thermal insulator and electrical insulator. The thermal insulator is made of coaxial double-layer metal bellows, which is also ready-made. The electrical insulator uses the shielding layer on the outside of the usual cable. Lin Yi finally added a protective layer to make a second Protect.

The rough version of the high-temperature superconducting cable he completed in two afternoons looks like an upside-down funnel, with layers of unknown metal in the middle, and it really doesn't look like something with any technological content.

"Liquid nitrogen and direct current preparation."

Although Lin Yi is confident, looking at this crude gadget in front of him, it is impossible for him to be honest. After all, when he was in his position in his previous life, he rarely did a full set of experiments by himself.

He Qun swallowed, "Researcher Lin, we are in the hotel now."

He wanted to remind Lin Yi that they were in a hotel instead of a laboratory. If something happened, it would be bad if they were arrested as terrorists.

"Don't worry, it's just a small experiment, you just need to look at the numbers on the current monitor."

One hundred thousand dollars, one hundred thousand dollars, He Qun thought to himself, took out the instrument hesitantly, and connected it to one end of the superconducting cable.

"Discharge!"

"Received." He Qun gritted his teeth and pressed the switch.

One second, two seconds... No response?

Lin Yi frowned, "No electricity? Why did you bring a broken machine here!"

The machine is broken?He Qun was nervous at first, then he breathed a sigh of relief in his heart, it's fine if it's broken, it's fine if it's broken.

But before he could breathe out, Lin Yi set his eyes on the socket of the room lamp.

Anyone who studies physics has never studied circuits. As a science student, I am ashamed to say that I have studied physics without taking circuits in the university dormitory.

Lin Yi took out a screwdriver from the toolbox and walked to the switch.

"Is there a rectifier?" The electricity connected to the circuit is alternating current, and a rectifier is needed to convert it into a direct current that can be used in experiments.

Unfortunately, there are.

Nothing in the world can stop a researcher who wants to see results immediately. Lin Yi pulled out a wire very smoothly and connected it to the rectifier.

"cable."

"Okay." He Qun handed the simple cable interface to Lin Yi.

The port access went smoothly, and He Qun stared at the numbers on the instrument without blinking, access and output...

"Successful, Researcher Lin, the difference between incoming and outgoing current is within the standard range, and the resistance is almost negligible..."

"Peng" seemed to be the sound of something exploding, and a burning smell entered the nasal cavity of the two, followed by the exclamation of the residents on the same floor, and the sound of people running.

Lin Yi was silent for 2 minutes, "Turn off the machine. There is still waiting for compensation, you use my card to go to the front desk to swipe..."

"OK……"

But before He Qun finished packing the instruments in the dark, Lin Yi's door was violently opened.

"Don't move, you are surrounded!"

The author has something to say: Police: Be honest, what other accomplices do you have here!

Lin Yi: Yes, Zhuang Cheng, associate professor of Stanford Department of Physics

Policemen:……
