Scholar’s Advanced Technological System

Not far from the university town of Jinling City, in the newly planned high-tech park of the city government, the factory of Baosheng Group is located.

In the center of the spacious workshop, there is a large-scale production equipment.

From the appearance, the appearance of this device is still a little weird, or rude, or even a bit like a product of patchwork.

If it were not introduced, I am afraid no one would think that this seemingly sci-fi stuff is actually the core equipment in the production process of graphene wires with a width of several thousand nanometers. Nor would anyone think that the thin silver wires connected between the slowly opened and closed metal plates are SG-1 wires that are comparable in price to gold of equal weight.

Of course, this is only for now.

When the production process and equipment are improved and the production scale goes up, the cost will naturally come down.

Just then, footsteps came from outside the plant.

I noticed the sound from the outside. Several engineers in the factory building looked towards the doorway and saw a group of people walking towards the factory building under the leadership of Manager Sun and Cao Gong.

Wiping the sweat from his face, looking at the young man who made Manager Sun's face full of laughter, an engineer couldn't hold back the curiosity in his heart, and asked a colleague next to him.

"Who is that person?"

"Which?"

"The one next to Manager Sun."

"Lu Zhou, don't you watch the news?"

"Lu Zhou? The one who won the Nobel Prize?"

"if not?"

"Amazing ... Nobel laureate came to our factory to investigate. Is this the news tomorrow?"

Not to mention the news, maybe even the stock price has to go up.

Although superconducting materials are not a popular subject matter in A shares, the meaning is completely different when they are put together with the name Lu Zhou.

After all, how popular the lithium battery market is, it is obvious to the whole world.

After whispering a few words, when Manager Sun and his party came over, several engineers stopped speaking.

At the same time, under the leadership of Cao Gong, he walked to the equipment in the center of the factory building. Several German experts finally saw the legendary graphene nanobelt capable of mass production of several thousand nanometers.

With a hint of contempt and suspicion from the bottom of his heart, Simson Eugene looked up and down the device without mechanical beauty.

From a subjective point of view, he really can't believe that this simple device can do nano-level finishing.

But soon, his gaze became more and more dignified, and he was finally stuck on the device, completely unable to move.

Thin silver wires were connected in the middle of the two metal plates, as if planted on them. One side of the thinner metal plate is connected with a sieve-like ring, and the growing thin wire is guided to one side, and it is bundled in the ring with the thumb.

Even though the two metal plates are opening and closing as slowly as a snail crawls, it is indeed producing ...

Just looking at the appearance, he couldn't imagine how they did it.

Standing next to Eugene, Ulic, with a slightly older face, asked seriously: "Is that all?"

Lu Zhou smiled and introduced easily: "This is the core part of the entire production process. You can understand it as the drawing machine in the cable production line ... although the two things are completely different in principle. thing."

Eugene couldn't help but asked, "Are you sure this guy ... produces graphene wires that are only a few thousand nanometers wide?"

Lu Zhou glanced at him and continued: "Just listening to me alone is a little less persuasive. In that case, you can take a section from the product and let us take a test together."

Hearing Lu Zhou's words, Eugene was unpretentious, walked to the machine, and with the help of another Huaguo engineer, took a short piece of SG-1 wire from the equipment and put it into the sample prepared in advance. In the bag.

When he came to the product quality inspection room, looking at the tunnel scanning electron microscope, the red-haired German engineer asked for help.

"Can you let me come?"

Lu Zhou gestured please: "Of course."

Stepped forward and inspected the equipment carefully. Eugene loaded the sample into the equipment and skillfully operated a very fine probe through a computer, aiming at the side of the SG-1 wire with a diameter of only a few thousand nanometers.

Soon, the probe fed the collected data back to the computer screen.

When you saw the data collected by the tunnel scanning electron microscope and the three-dimensional atomic structure diagram processed by the graphic simulation technology, it was not only Eugene, including the leading professor Ulrich, the look on the faces of the six German experts could not help but slightly Move.

I ca n’t believe everything in front of me, like grabbing the last straw, Eugene asked hard: “What about superconductivity?”

"I guess you probably want to ask this question," Lu said, looking at the researcher standing next to the scanning electron microscope, and instructed, "show them to them."

The wires were removed from the tunnel scanning electron microscope and transferred to another experimental device.

Keithley's 2182A nanovoltmeter and 6220 current source, as well as pipes and temperature controllers for introducing liquid helium were installed on this experimental equipment.

The final measurement results are also obvious. The "resistance / temperature" curve that quickly drops to the floor after approaching the transition temperature is exactly the same as the picture that Professor Kreiber originally saw at the Jinling Institute of Advanced Studies.

Even if he didn't want to believe it, Eugene must not be gravely convinced at this moment.

They did it ...

"Inconceivable ... how did you do it?"

Lu Zhou: "Simply speaking, it is to stack monoatomic rhodium metal sheets, then punch holes on it, adjust the overlap angle, and then use the principle of chemical vapor deposition to deposit SG-1 material in the pores. The obtained longitudinally stacked graphene nanoribbons are as if grown in a specific form ... The general process is like this. As for more specific technical details, in the future, engineers from Baosheng Group will Give you detailed instructions. "

Dr. Ulrich frowned, and asked an academic question: "Monatomic layer metal flakes? How do you guarantee its monoatomic layer structure?"

The non-directional nature of metal bonds can easily form a three-dimensional close-packed structure. In theory, such single-atom-thick metal flakes are difficult to prepare. And even if it is prepared, it is difficult to guarantee this kind of monoatomic layer characteristics.

Lu Zhou smiled and said, "Nothing special is needed."

Ulrich stunned slightly. "Nothing needs to be done?"

Lu Zhou nodded: "Yes, there is a special delocalized large π bond in the monoatomic layer of rhodium metal flakes, which helps stabilize its single layer structure."

This is a research result that has only come out in the last two years.

In fact, this is why he chose rhodium.

Although the price of rhodium is a bit more expensive, because of the extremely difficult to oxidize rhodium metal, this kind of monoatomic flakes can be used repeatedly as a mold for a long time, so the cost is generally acceptable.

As for how to prepare single-atom-thick metal rhodium flakes, as he mentioned earlier, it was prepared by reducing the weak ligand polyvinylpyrrolidone with formaldehyde.

Later, this group of German experts asked a lot of questions, and Lu Zhou was able to answer all of them and answered them one by one. As for the part beyond the theoretical scope he understood, he was given to Chief Engineer Cao to answer.

Stayed in the high-tech park until the evening.

When leaving, Yang Xu, who was in the same car as Lu Zhou, couldn't help feeling a sigh.

"I didn't expect that one day we would also ~ www.readwn.com ~ be able to conquer the Germans technically."

Lu Zhou smiled and said in a chatty tone: "German industrial technology is very strong, especially in the field of finishing and automation, we still have a big gap to catch up with. But they are not gods, and there is no need to transition to mythology. "

There isn't much to say about where you've lost at the starting line, but at least in the area of ​​new technology, everyone is searching for ways to find out, and the starting line is naturally similar.

With the help of Jinling Institute of Computing Materials, Baosheng Group was fortunate to place the starting line in front of other people. If nothing else, relying on the blood transfusion of domestic controllable fusion project orders, as long as it is not dead, There is not much problem in continuing to lead in carbon-based superconducting materials.

As for the more distant future, and even the overall strength of the country's manufacturing ...

Those things are not things that Lu Zhou can control.

What he is interested in is just research.

...

In the evening, I returned to the villa of Zhongshan International, sat on the boat in the study, and Sheng Xianfu, who had already arrived in Germany, made a phone call.

"You have arrived safely?"

Sheng Xianfu: "I arrived in Berlin yesterday evening and we have now arrived in Greifswald."

"Is WEGA in Greifswald?"

Lu Zhou recalled his last trip to Greifswald and did not seem to see the WEGA installation there.

Sheng Xianfu: "That's not true, it's just that the first phase of training will take place at the Spiral 7-X laboratory."

After hearing this, Lu Zhou joked, "The training fee is 500 million yuan, so you have to work hard."

Professor Sheng, holding the phone, nodded seriously.

"Absolutely!"
