Chapter 496: Conquering the Germans with Technology (2/3)
Not far from the university town of Jinling City, in the newly planned high-tech park of the municipal government, there is a factory of Baosheng Group.
In the center of the spacious factory building is a bulky production facility.
From the outside, the appearance of this device is still somewhat eccentric, or rather shabby, and even a bit like a patchwork product.
If someone hadn't introduced it, I'm afraid no one would have thought that this thing that doesn't seem to have a sense of science fiction is actually the core equipment in the production process of graphene wires with a width of thousands of nanometers. No one would have thought that the thin silver wires connected between the slowly opening and closing metal plates were SG-1 wires that cost as much weight as gold.
Of course, that's just for now.
When the production process and equipment are improved, and the scale of production goes up, the cost will naturally come down.
At this moment, footsteps were heard outside the factory.
Noticing the sound outside, several engineers in the factory looked in the direction of the door, only to see a group of people walking towards the factory under the leadership of Manager Sun and Cao Gong.
Wiping the sweat from his face, looking at the young man who made Manager Sun smile all over his face, an engineer couldn't hold back the curiosity in his heart, and asked a colleague next to him.
"Who's that guy?"
"Which one?"
"The one next to Manager Sun."
"Lu Zhou, don't you watch the news?"
"Lu Zhou? The one who won the Nobel Prize? ”
"Or else?"
"Awesome...... Nobel laureates come to our factory for research, I'm afraid it will be in the news tomorrow, right? ”
Not to mention being on the news, maybe even the stock price will have to go up.
Although superconducting materials are not a hot topic in A-shares, when put together with the name Lu Zhou, the meaning is completely different.
After all, how hot the lithium battery market is, it is obvious to the whole world.
After a few words, they saw Manager Sun and his party coming over, and several engineers stopped talking.
At the same time, under the leadership of Cao Gong, they walked to the equipment in the center of the factory, and several German experts finally saw the legendary graphene nanoribbon that can be mass-produced with a width of several thousand nanometers.
With a hint of contempt and suspicion from the depths of his heart, Simson Eugene looked the device up and down a few times.
Subjectively, he couldn't believe that this rudimentary machine could do nanometer finishing.
Soon, however, his gaze became more and more solemn, and finally he was stuck to the device, unable to move away at all.
Thin silver wires are attached between the two metal plates, as if they were planted on them. On one side of the thinner metal plate, a sieve-like ring is attached to guide the thin threads that grow to one side and bundle them in a thumb-sized ring.
Even though the two metal plates open and close as slowly as a snail, they are actually producing......
Just looking at the appearance, he couldn't imagine how they did it.
Standing next to Eugene, Ulich, with a slightly old face, asked solemnly, "Is that all?" ”
Lu Zhou smiled and introduced in a relaxed tone: "This is the core part of the entire production process, and you can understand it as a wire drawing machine in the cable production line...... Although the two things are completely different things in principle. ”
Eugene couldn't help but ask, "Are you sure this guy ...... Is it the kind of graphene wire that is only a few thousand nanometers in width produced? ”
Lu Zhou glanced at him and continued: "Just listening to me alone is indeed a little less convincing, in that case, you can take a screenshot from the product, and let's take it for a test together." ”
Hearing Lu Zhou say this, Eugene did not pretentiously, walked to the side of the machine, and with the help of another Huaguo engineer, took a small section of SG-1 wire from the equipment and put it into the sample bag prepared in advance.
When I came to the product quality inspection room and looked at the tunnel scanning electron microscope, the red-haired German engineer took the initiative to ask for help.
"Can you let me come?"
Lu Zhou made a gesture of please: "Of course you can." ”
Walking up and carefully inspecting the equipment, Eugene loaded the sample onto the device and, skillfully manipulating the extremely fine probe through the computer, aimed at the side of the SG-1 wire, which was only a few thousand nanometers in diameter.
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 Ulich, who led the team, couldn't help but be slightly moved on the faces of these six German experts.
Unable to believe what was in front of him, as if grasping at the last straw, Eugene asked with difficulty, "What about superconductivity?" ”
"I guess you're probably going to want to ask," Lu Zhou said, looking at the researcher standing next to the SEM and instructing, "Show them it." ”
The wires were removed from the tunnel SEM and transferred to another experimental device.
On this experimental equipment are Keithley Nano 2182A nanovolt meter and 6220 current source, as well as piping and temperature controller for liquid helium induction.
The final measurement is also obvious, the "resistance/temperature" curve that falls quickly to the floor after approaching the transition temperature is exactly the same as the picture that Professor Kreber saw at the Jinling Institute for Advanced Study.
Even if he didn't want to believe it, Eugene couldn't help but be unconvinced of it at this moment.
And they did......
"Incredible...... How do you do that? ”
Lu Zhou: "To put it simply, the rhodium metal sheets of the single atomic layer are stacked, then punched holes on them, and the overlap angle is adjusted, and then the SG-1 material is deposited in the pores using the principle of chemical vapor deposition...... The general process flow is like this, as for the more specific technical details, in the coming period, the engineers of Baer Group will give you a detailed explanation. ”
Dr. Ulic frowned and asked a more academic question: "Monoatomic layer metal flakes?" How do you guarantee its monoatomic layer structure? ”
The non-directional nature of metal bonds is very easy to form a three-dimensional tightly packed structure, and it is theoretically difficult to prepare such metal sheets with a thickness of a single atom. And even if it is prepared, it is difficult to ensure this single-atomic layer characteristic.
Lu Zhou smiled and said, "There is no need to do anything special." ”
Ulic was slightly stunned: "Don't need to do anything?" ”
Lu Zhou nodded: "Yes, there is a special delocalized large π bond in the rhodium metal sheet of the monoatomic layer, which helps to stabilize its monolayer structure. ”
This is a study that has only been published in the last two years.
In fact, this is why he chose rhodium metal.
Although the price of rhodium is a bit more expensive, because rhodium metal is extremely difficult to oxidize, this kind of single-atom sheet can be used as a mold for a long time, so the overall cost is still acceptable.
As for how to prepare metal rhodium flakes with a single-atom thickness, as he mentioned earlier, it is prepared by using the weak ligand polyvinylpyrrolidone and formaldehyde reduction.
Later, this group of German experts asked a lot of questions, and Lu Zhou answered everything he could answer, and as for the part that was beyond the scope of the theory he understood, it was handed over 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.
"I didn't expect that we would be able to conquer the Germans one day."
Lu Zhou smiled and said in a casual tone: "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 either, and there is no need to transition to mythology. ”
There is nothing to say about the places that have 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 about the same.
With the help of the Jinling Institute of Computational Materials, Baosheng Group is fortunate to put the starting line in front of others, and if nothing else, with the blood transfusion of domestic controllable nuclear fusion project orders, as long as it does not waste or die, it will not have much problem 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 not something that Lu Zhou can control.
He was only interested in research.
……
In the evening, I returned to the villa of Zhongshan International, and Lu Zhou, who was sitting in the study, had a phone call with Sheng Xianfu, who had arrived in Germany.
"You've arrived safely?"
Sheng Xianfu: "We arrived in Berlin yesterday evening, and we have now arrived in Greifswald. ”
"Is EGA in Greifswald?"
Lu Zhou recalled the last time he went to Greifswald, and he didn't seem to see the EGA device over there.
Sheng Xianfu: "That's not really, it's just that the first phase of training will be held at the Spiral Stone 7-X Laboratory. ”
Hearing this, Lu Zhou made a joke and said: "The training fee is 500 million, you have to work hard." ”
Professor Sheng, who was holding his mobile phone, nodded seriously.
"That's a must!"
