Not far from Jin Ling University, Baosheng Group's factory was located in the high-tech zone newly planned by the municipal government.
In the middle of the spacious factory, there was a huge production equipment.
From the outside, the appearance of this device was somewhat strange, or perhaps it could be said that it was simple and crude, even a little like a product that was pieced together.
If someone didn't introduce it, no one would have thought that this thing that didn't look like science fiction was actually the core equipment in the production process of graphene wires that were thousands of nanometers wide. No one would have thought that the thin silver wires connected between the metal plates were the SG-1 wires, which were comparable to the price of gold.
Of course, this was only for the time being.
Once the production process and equipment were improved, the production scale would increase, and the cost would naturally decrease.
Suddenly, footsteps came from outside the factory.
Several engineers in the factory heard the noise outside, and they looked in the direction of the door. They saw a group of people led by General Manager Sun and Engineer Cao walking into the factory.
An engineer wiped the sweat off his face and looked at the young man who made General Manager Sun smile. He couldn't help but be curious, and he asked his colleague next to him.
"Who's that?"
"Which one?"
"The one next to General Manager Sun."
"Lu Zhou, don't you watch the news?"
"Lu Zhou? The one who won the Nobel Prize? "
"What else?"
"Amazing … A Nobel Prize winner coming to our factory for research, this will probably be on the news tomorrow, right?"
Not to mention appearing on the news, even the stock price might rise.
Although superconducting materials weren't a popular topic in the A-share market, when it was put together with the name Lu Zhou, the meaning was completely different.
After all, the lithium-ion battery market was very popular, and everyone in the world knew that.
The engineers whispered to each other and saw General Manager Sun and the others walk over. They stopped talking.
At the same time, Engineer Cao led them to the equipment in the middle of the factory. The German experts finally saw the legendary graphene nanoribbons that could be mass-produced thousands of nanometers wide.
With a trace of contempt and suspicion that came from the bottom of his heart, Simson Eugene sized up the device that had no sense of mechanical beauty.
From a subjective point of view, he really couldn't believe that this simple equipment could achieve nano-level precision processing.
However, very quickly, his gaze became more and more serious. In the end, his eyes were glued to the device and he could not move them away at all.
Thin silver lines were connected between the two metal plates, as if they were planted on them. One side of the thinner metal plate was connected to a sieve-like ring, guiding the thin lines to one side and binding them into the thumb-sized ring.
Even though the speed at which the two metal plates opened and closed was as slow as a snail's crawl, it was indeed producing …
Just by looking at it, he couldn't imagine how they did it.
Standing next to Eugene, the slightly aged Ulic asked solemnly, "Is that all?"
Lu Zhou smiled and said in a relaxed tone, "This is the core of the entire production process. You can think of it as the wire drawing machine in the cable production line … Although the two things are completely different in principle."
Eugene couldn't help but ask, "Are you sure this guy … is producing the kind of graphene wire that is only a few thousand nanometers wide?"
Lu Zhou looked at him and said, "It's not convincing if I'm the only one saying it. Since this is the case, why don't you take a snippet from the product, and we can test it together."
When Eugene heard Lu Zhou say this, he didn't argue. He walked next to the machine and with the help of another China engineer, he took a small section of the SG-1 wire from the device and put it into a sample bag prepared in advance.
When they came to the product quality testing room, the red-haired German engineer looked at the scanning electron microscope and volunteered.
"Can I do it?"
Lu Zhou made an inviting gesture and said, "Of course."
Eugene walked up and carefully inspected the device. He installed the sample into the device and skillfully operated the extremely thin probe through the computer. He aimed it at the side of the SG-1 wire with a diameter of only a few thousand nanometers.
Soon after, the data collected by the probe was fed back to the computer screen.
When the six German experts saw the data collected by the scanning electron microscope and the three-dimensional atomic structure diagram processed by graphic simulation technology, not only Eugene, but even Professor Ulic, who was leading the team, couldn't help but be moved.
Eugene couldn't believe what was happening in front of him. He asked, "What about the superconductivity?"
"I knew you guys would probably ask this." Lu Zhou looked at the researcher standing next to the scanning electron microscope and said, "Show them."
The wire was removed from the scanning electron microscope and transferred to another piece of experimental equipment.
This experimental device was installed with a Keithley 2182A nanovoltmeter and a 6220 current source, as well as a pipeline and temperature controller for the liquid helium.
The final measurement result was obvious. The "resistance/temperature" curve quickly fell to the floor when it approached the transition temperature. It was exactly the same as the picture Professor Keriber saw at the Jinling Institute for Advanced Study.
Even though Eugene didn't want to believe it, he couldn't help but believe it.
They did it …
"Unbelievable … How did you do it?"
Lu Zhou: "Simply put, it's stacking the monolayer of rhodium metal sheets, then drilling holes on them, adjusting the overlap angle, then using the principle of chemical vapor deposition to deposit the SG-1 material in the pores. On a macroscopic level, the longitudinal stacked graphene nanoribbons are like they are grown in a specific form … This is the general process flow. As for the more specific technical details, Baosheng Group's engineers will explain them to you in detail."
Dr. Ulic frowned and asked an academic question, "Monolayer metal sheet? How did you ensure its monolayer structure? "
The directionless nature of the metal bond made it easy to form a three-dimensional close-packed structure. In theory, it was difficult to prepare this kind of monolayer metal sheet. Even if it was prepared, it was difficult to guarantee this kind of monolayer characteristics.
Lu Zhou smiled and said, "You don't have to do anything special."
Ulic said, "You don't have to do anything special?"
Lu Zhou nodded and said, "Yes, there is a special delocalized large π bond in the monolayer of rhodium metal sheet, which helps to stabilize its monolayer structure."
This was a research result that came out in the last two years.
In fact, this was the reason why he chose rhodium metal.
Even though rhodium was a bit expensive, because rhodium was extremely difficult to oxidize, this kind of monolayer could be used as a mold for a long time. Therefore, the overall cost was still acceptable.
As for how to prepare the monolayer of rhodium metal sheet, just like the method he mentioned before, he used a weak ligand, polyvinyl pyrrolidone, to reduce it with formaldehyde.
Afterward, this group of German experts asked a lot of questions, and Lu Zhou answered them one by one. As for the parts that were beyond his theoretical understanding, Chief Engineer Cao answered them.
They stayed in the high-tech zone until the evening.
When they left, Yang Xu, who was sitting in the same car as Lu Zhou, couldn't help but sigh.
"I didn't think we would have a day where we would be able to conquer the Germans in technology."
Lu Zhou smiled and said, "The German industrial technology is very strong, especially in the field of precision processing and automation. We still have a big gap to catch up to. But they aren't gods, so there's no need to be mythical. "
There was nothing to say about losing at the starting line, but at least in the field of new technology, everyone was trying to find a solution, so the starting line was naturally the same.
With the help of the Jinling Institute of Computational Materials, Baosheng Group was lucky enough to have a head start in the carbon-based superconducting materials industry. If everything went well, with the help of the domestic controllable nuclear fusion project, as long as it didn't do anything stupid, it wouldn't be a problem for it to continue to lead the carbon-based superconducting materials industry.
As for the future and the overall strength of the country's manufacturing industry …
Those things weren't something that Lu Zhou could control.
The only thing he was interested in was research.
…
At night, Lu Zhou returned to his Zhongshan International mansion. He was sitting in his study room when he called Sheng Xianfu, who had already arrived in Germany.
"You guys have arrived safely?"
Sheng Xianfu: "We arrived in Berlin yesterday evening. We're now in Greifswald."
"Is WEGA in Greifswald?"
Lu Zhou recalled his last trip to Greifswald. He didn't remember seeing the WEGA machine there.
Sheng Xianfu: "Not exactly, it's just that the first stage of training will be conducted at the Wendelstein 7-X laboratory."
Lu Zhou joked and said, "The training fee is 500 million yuan, you guys have to work hard."
Professor Sheng, who was holding his phone, nodded seriously.
