Scholar’s Advanced Technological System

Not far from the Jinling City University City, the municipal government's newly planned high-tech park is located in the Baosheng Group's factory.

In the middle of the spacious factory, there is a huge production facility.

From the appearance, the appearance of this device is still somewhat weird, or rather rudimentary, and even a bit like a patchwork.

If it wasn’t for someone to introduce it, I’m afraid no one would have thought that this seemingly sci-fi-free thing would be the core equipment in the process of producing thousands of nanometers of graphene wire. No one would have thought that the silver thread that was connected between the slowly opening and closing metal plates was comparable to the sg-1 wire of equal weight.

Of course, this is only for the present.

The production process and equipment have been improved, and the production scale has gone up, and the cost has naturally come down.

At this time, footsteps came from outside the factory.

I noticed the sound outside. Several engineers in the factory looked in the direction of the door. I saw a group of people walking under the leadership of Sun and Cao Gong.

Wiping the sweat on his face and looking at the young man who made Sun’s manager full of laughter, an engineer couldn’t stand the curiosity in his heart, and asked the colleague next to him.

"Who is that person?"

"Which?"

"The one next to Sun’s manager."

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

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

"if not?"

"It's amazing... Nobel Prize winners come to our factory for research. Is this afraid of getting news tomorrow?"

Not to mention the news, and not sure that the stock price has to go up.

Although superconducting materials are not a hot topic in a-shares, the meaning of Luzhou is completely different.

After all, the market for lithium batteries is hot, but the world is obvious to all.

I whispered a few words and saw that Sun’s team came over and several engineers stopped talking.

At the same time, under the leadership of Cao Gong, he walked to the equipment in the center of the factory. Several German experts finally saw the legendary nanometer-sized graphene nanobelts capable of mass production.

With a glimpse of suspicion and suspicion from the bottom of his heart, Simson Eugene looked up and down the device with no mechanical beauty.

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

However, soon his vision became more and more dignified, and he was finally glued to the device and could not move completely.

A pair of silver thin wires are connected in the middle of the two metal plates as if they were planted on them. One side of the thinner metal plate is connected to a sieve-like ring, and the thin wire that grows is directed to one side and is converged in a large ring of thumb.

Even if the speed of opening and closing the two metal plates is as slow as the snail crawling, it is indeed producing...

Looking at the appearance alone, he couldn't imagine it, how they did it.

Standing next to Eugene, Ulic, who looked a little old, asked seriously: "Only these?"

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

Eugene couldn't help but ask: "Are you sure this guy... is producing a graphene wire with only a few thousand nanometer widths?"

Lu Zhou glanced at him and continued: "It’s just to listen to me alone. It’s really less convincing. If that’s the case, you can take a break from the product and we will take it together for a test.”

After hearing Lu Zhou say this, Eugene did not have any sentimentality. He walked to the side of the machine. With the help of another Chinese engineer, he took a small sg-1 wire from the equipment and put it into the prepared sample. In the bag.

Came to the product quality testing room, looking at the tunnel scanning electron microscope, the red-haired German engineer took the initiative to ask.

"Can you let me come?"

Lu Zhou made a gesture of asking: "Of course."

Going forward, carefully inspecting the equipment, Eugene installed the sample on the device, and expertly operated a very fine probe through a computer, aligning the side of the sg-1 wire with a diameter of only a few thousand nanometers.

Soon, the probe feeds back the collected data on the computer screen.

When I saw the data collected by the tunnel scanning electron microscope and the three-dimensional atomic structure diagram processed by the graphic simulation technology, not only Eugene, including the leading Professor Ulic, the faces of these six German experts could not help but look down. Moving.

I can't believe everything in front of me, like grabbing the last straw, Eugene asked hard: "What about superconducting performance?"

"I guess you probably want to ask this question," he said, and Lu Zhou looked at the researcher standing next to the scanning electron microscope and told him, "Show them to them."

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

The Keithley Model 2182a Nanovoltmeter and Model 6220 current source were installed on this experimental equipment, as well as piping and temperature controllers for introducing liquid helium.

The final measurement is also obvious. The “resistance/temperature” curve that quickly falls to the floor after the transition temperature is exactly the same as that seen by Professor Kreb at the Jinling Institute of Advanced Studies.

Even if you don't want to believe it, Eugene can't be too heavy to be convinced at this moment.

They did it...

"Unbelievable... How did you do it?"

Lu Zhou: "In simple terms, the monocrystalline layer of tantalum metal is stacked, then perforated, and the overlap angle is adjusted. Then, the principle of chemical vapor deposition is used to deposit sg-1 material in the pores, macroscopically. The resulting longitudinally stacked graphene nanoribbons are like the ones that grow in a specific form... The rough process is like this. As for the more specific technical details, in the future, the Baosheng Group’s engineers will Give you a detailed explanation."

Dr. Ulic frowned and asked a partial academic question: "Single-atomic layer metal foil? How do you guarantee its monoatomic layer structure?"

The non-directionality of the metal bond is very easy to form a three-dimensional close-packed structure. Theoretically, such a single-atom thickness metal foil is difficult to prepare. And even if it is prepared, it is difficult to guarantee this monoatomic layer property.

Lu Zhou smiled and said: "No need to do anything special."

Ulics sighed slightly: "What do you need to do?"

Lu Zhou nodded: "Yes, there is a special delocalized large π bond in the enamel metal sheet of the monoatomic layer, which helps to 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 base metals.

Although the price of niobium is expensive, the monoatomic sheet can be used as a mold for a long time because of the extremely difficult oxidation properties of the niobium metal, so the cost is generally acceptable.

As for how to prepare a monocrystalline thickness of the metal ruthenium, as in the method he previously mentioned, it is obtained by reducing the weak ligand polyvinylpyrrolidone with formaldehyde.

Later, this group of German experts asked a lot of questions, and Lu Zhou could answer them one by one. As for the part of the theoretical scope that he understood, he gave it to Chief Engineer Cao to answer.

In the high-tech park has been waiting for the evening.

When leaving, Yang Xu, who was on the same car as Lu Zhou, couldn’t help but feel a word.

"I didn't expect that we have such a day, we can conquer Germany in technology."

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

There is nothing to say about the place that has already lost on the starting line, but at least in the field of new technology, everyone is looking for ways to find out, and the starting line is naturally similar.

With the help of Jinling Institute of Computational Materials, Baosheng Group is fortunate to put the starting line in front of other people. Without accident, with the blood transfusion of orders for domestic controllable nuclear fusion projects, as long as it does not kill, There is not much problem with continuing to lead on carbon-based superconducting materials.

As for the farther future, and even the overall strength of the national manufacturing industry...

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. Lu Zhou, who was sitting in the study room, and Sheng Xianfu, who had arrived in Germany, had a phone call.

"You have arrived safely?"

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

"Wega in Greifswald?"

Lu Zhou recalled the last experience of going to Greifswald, and did not seem to see the wega installation there.

Sheng Xianfu: "That is not the case, only the first stage of training will be carried out at the spiral stone 7-x laboratory."

After hearing this, Lu Zhou made a joke and said: "The training fee is 500 million yuan. You can get well."

Professor Sheng holding the mobile phone, seriously pointed to the next.

"That's a must!"
