497 Conquer The Germans With Technology (2/3)

Chapter 497 Conquering the Germans with technology (23)

Not far from the University City of Jinling City, the factory of Baosheng Group is located in the new high-tech park planned by the city government.

In the center of the spacious workshop, there is a huge production equipment.

From the appearance, the appearance of this device is somewhat strange, or crude, and even a bit like a product of patchwork.

If it hadn't been introduced by someone, I am afraid no one would have thought that this seemingly non-sci-fi thing is actually the core equipment in the production process of the graphene wire with a width of several thousand nanometers. No one would have thought that the thin silver wires connected between the slowly opening and closing metal plates are the SG-1 wires whose price is comparable to that of gold of equal weight.

Of course, this is only for now.

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

At this moment, footsteps came from outside the factory building.

Noticing the sound outside, several engineers in the factory looked towards the door, and saw a group of people walking towards the factory under the leadership of Manager Sun and Cao Gong.

Wiping the sweat off his face, looking at the young man who made Manager Sun smile all over his face, an engineer couldn't hold back his curiosity, and asked the colleague next to him.

"Who is that person?"

"Which one?"

"The one next to Manager Sun."

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

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

"if not?"

"It's amazing...the Nobel Prize winner came to our factory for research. I'm afraid it will be on the news tomorrow, right?"

Not to mention it's on the news, maybe even the stock price has to go up a bit.

Although superconducting materials are not a hot topic in the A-share market, but together with the name Lu Zhou, the meaning is completely different.

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

After whispering a few words, seeing Manager Sun and his party approaching, the engineers stopped talking.

At the same time, under Cao Gong's leadership, they walked to the equipment in the center of the factory building, and several German experts finally saw the legendary graphene nanoribbons capable of mass-producing thousands of nanometers in width.

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

From a subjective point of view, he really couldn't believe that this crude equipment could achieve nanometer-level finishing.

However, soon, his gaze became more and more serious, and finally he was firmly glued to the device, unable to move away at all.

Thin silver lines are connected between the two metal plates, as if planted on them. One side of the thinner metal plate is connected to a sieve-like ring, which guides the growing thin wires to one side and gathers them in the thumb-sized ring.

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

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

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

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

Eugene couldn't help asking: "Are you sure this guy... is producing graphene wires that are only a few thousand nanometers wide?"

Lu Zhou glanced at him, and continued: "It's really not convincing just to listen to me alone. If that's the case, you can intercept a section from the product and let's take it for a test together."

Hearing what Lu Zhou said, Eugene didn't show any pretense, and walked to the machine. With the help of another Huaguo engineer, he sampled a short section of SG-1 wire from the equipment and put it into the prepared sample. in the bag.

When I came to the product quality inspection room, looking at the tunnel scanning electron microscope, the red-haired German engineer volunteered.

"Can I come?"

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

Going forward and carefully inspecting the equipment, Eugene installed the sample on the equipment, skillfully manipulated the extremely thin probe through the computer, and aimed at the side of the SG-1 wire whose diameter is only a few thousand nanometers wide.

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

When they 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, but also Professor Ulrich who led the team, the expressions on the faces of the six German experts could not help but be slightly Moved.

Really unable to believe everything in front of him, as if grabbing the last straw, Eugene asked with difficulty: "What about superconductivity?"

"I guess you probably want to ask this question," Lu Zhou said, looking at the researcher standing next to the scanning electron microscope, and ordered, "Let's demonstrate it to them."

The wires were removed from the tunneling SEM and transferred to another experimental device.

Keithley Model 2182A nanovoltmeter and Model 6220 current source are installed on this experimental equipment, as well as pipelines and temperature controllers for introducing liquid helium.

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 Kleiber saw at the Jinling Institute for Advanced Study.

Even if he didn't want to believe it, at this moment Eugene couldn't help being unsure of it with a heavy heart.

They did...

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

Lu Zhou: "To put it simply, it is to stack single-atom-layer rhodium metal sheets, then punch holes on them, and adjust the overlapping angle, and then use the principle of chemical vapor deposition to deposit SG-1 material in the pores. The obtained vertically stacked graphene nanoribbons seem to be grown in a specific form... The general process flow is like this. As for more specific technical details, in the future, the engineers of Julius Baer Group will I will explain it to you in detail."

Dr. Ulrich frowned and asked an academic question: "Monatomic layer metal flakes? How do you ensure its single atomic layer structure?"

The non-directionality of metal bonds can easily form a three-dimensional close-packed structure. Theoretically, it is difficult to prepare such a single-atom-thick metal flake. And even if it is prepared, it is difficult to guarantee this single atomic layer characteristic.

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

Ulrich was slightly taken aback: "No need to do anything?"

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

This is the result of a study that came out in the last two years.

In fact, that's why he chose rhodium.

Although the price of rhodium is a bit expensive, because of the extremely difficult oxidation of rhodium metal, this single-atom sheet can be used repeatedly as a mold for a long time, so the overall cost is still acceptable.

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

Later, the group of German experts asked a lot of questions, and Lu Zhou answered everything he could answer. As for the part beyond the theoretical scope he understood, he gave it to Chief Engineer Cao to answer.

I 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 but sigh with emotion.

"I didn't expect that one day we would be able to conquer the Germans technically."

Lu Zhou smiled and said in a chatty tone: "Germany's industrial technology is very strong, especially in the fields of finishing and automation. We still have a lot to catch up with. But they are not gods, so there is no need to transition to mythology. "

There is nothing to say about the places that have already lost at the starting line, but at least in the field of new technologies, everyone is groping for a way, and the starting line is naturally similar.

With the help of Jinling Institute of Computing Materials, Julius Baer Group was lucky to put the starting line ahead of others. If there is no accident, relying on the blood transfusion of domestic controllable nuclear fusion project orders, as long as it does not waste or die, There is no big 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 industry...

Those things are beyond Lu Zhou's control.

What he is interested in is just research.

...

In the evening, after returning to Zhongshan International's villa, Lu Zhou, who was sitting in the study, had a phone call with Sheng Xianfu who had already arrived in Germany.

"Have you arrived safely?"

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

"Is WEGA in Greifswald?"

Lu Zhou recalled the experience of going to Greifswald last time, but he didn't seem to see the WEGA device there.

Sheng Xianfu: "That's not true, it's just that the first stage of training will be conducted at the spiral stone 7-X laboratory."

Hearing this, Lu Zhou joked, "The training fee is 500 million, you guys have to work hard."

Professor Sheng, who was holding the phone, nodded seriously.

"That's a must!"
