In the history of science, graphene was discovered in 2004 by the geim research team of the University of Manchester in the UK. Its characteristics, as Qin Hai said, are a single atomic layer graphite crystal film.＠,ww↙w.23w○x.c＄om
At that time, Geim and others used a "tear-off tape method" to obtain graphene. They first cut the graphite into thin slices, and then used a special tape to stick to both sides of the slice. After tearing it in reverse, the slice became one piece.
Two are glued to the tapes on both sides respectively. By repeating this process, you can get thinner and thinner graphite sheets, until you finally get a sheet with only one atom thickness, which is graphene.
After the discovery of graphene, it quickly attracted the attention of the materials science and condensed matter physics circles. Research on the properties of graphene became the most popular topic for a while, and research on corresponding preparation methods also made breakthroughs one after another, making the application of graphene
become possible.
Graphene has excellent mechanical properties, electrical properties, thermal properties and optical properties, and can be used to construct various high-performance nanodevices. Due to its monolayer structure, graphene can also be used to prepare unique chemical and electrical properties.
Chemical carbon-based materials, such as various film materials, aerogels, carbon foam, etc.
Businessmen have the sharpest vision. Once graphene came out, it attracted widespread attention in the economic field and was known as a "universal material." Many countries have invested in the development of the graphene industry, competing for this technology that may generate huge benefits.
peak.
As a time traveler, how could Qin Hai not know the value of graphene? However, due to technology and his own economic strength in the past few years, he had no time to take into account this material with huge potential. This time, he was ridiculed by Jing Jing
Enlightenment, he suddenly realized that the time should have been ripe for research on graphene.
Seeing that Qin Hai was serious, Jing Jing put away his teasing expression and said, "Qin Hai, are you sure there is such a material? In my impression, several professors from the University of Tokyo in Japan tried it a few years ago.
They tried to make single-layer graphite sheets, but failed. The single-layer graphite sheets they made could not exist independently at all. They quickly decomposed. There was a conclusion in the condensed matter physics community that "a perfect two-dimensional crystal structure cannot exist in a non-absolute state".
Stable existence below zero', do you want to break this law?"
Qin Hai smiled and said: "All judgments are meant to be broken, and this law you mentioned is no exception. But, don't worry about this matter for now, just study your iron-based superconductivity in a down-to-earth manner.
For the best. You can't do two things at once, so don't waste your time on other things."
"You're still talking about me, tell me how much you have used up your own concentration?" Jing Jing scolded.
"No, no, my whole heart is with you. There is absolutely no second use." Qin Hai confessed with a smile.
"Bah, who knew you..." Ning Jing was very dissatisfied with Qin Hai's deliberate confusion of concepts, and then retorted. But halfway through her words, she stopped talking. The topic of Qin Hai's multitasking seemed a bit sensitive.
It would be better for her to avoid it as much as possible.
After an encounter in the jewelry store, the two of them had no intention of continuing shopping. Ning Jing was thinking about his keynote speech tomorrow. He was anxious to rush back to the hotel to discuss it with his mentor Chen Zongze. Qin Hai, on the other hand,
Because I suddenly thought about the problem of graphene, I felt itchy and wanted to go back to the hotel quickly to discuss it with my subordinates.
The two took a taxi back to the hotel, went upstairs together, and then went their separate ways to do their own things. Ning Jing went back to the room to get the manuscript, and went to Chen Zongze's room to make the final touches with the instructor. Qin Hailian's room
Without replying, he went straight to the room of Nie Sen, an expert from the School of Materials.
Nie Sen is an expert recruited by Qin Hai from Pujiang. He has made some achievements in the research on the properties and preparation methods of nanomaterials. This time, he brought an article "Preparation of tin/private 3n4 ceramic nanocomposites by chemical vapor deposition"
" came to Paris to participate in the annual meeting of materials. Several ceramic nanocomposites he studied have been put into production at Quwu Ceramics Group, and are widely used in automobile engines, electronic components, etc., and have achieved good economic benefits.
, and precisely because of this, he is highly valued by Qin Hai.
When Qin Hai came to Nie Sen's room, Nie Sen was sitting at his desk looking through some academic books he had just bought on the street. Seeing Qin Hai's arrival, he was a little surprised. He quickly stood up and gave up his seat. At the same time, he asked with a smile: "Qin Hai
Boss, why are you here... Everyone was saying just now that you and Xiao Ning must have a candlelight dinner outside."
"Haha, I'm not that romantic." Qin Hai sat down on the sofa and said with a smile, "By the way, Professor Nie didn't tell me, I really ignored it. Next time we go out for a meeting, we should encourage everyone to bring their families.
, so that you, the great professors who have drunk foreign ink, can take your wives to have some romance."
Nie Sen studied abroad in his early years, so he was one of those people who drank foreign ink. Hearing what Qin Hai said, he smiled and said: "My wife and I are an old couple, so what's the point of being romantic?"
You and Xiao Ning are still young, so you should be more romantic. We all say that Mr. Qin and Xiao Ning are really a golden couple, a match made in heaven. Xiao Ning is so talented and has made such achievements in superconducting research at such a young age.
A great achievement, and Mr. Qin is thoughtful and financially powerful. Together, you two are a perfect match, both in life and career."
Qin Hai waved his hands and said with a smile: "That's all, I found that our School of Materials Science is really a place to train people. A scholar like you, Professor Nie, who is rigorous in his studies and unsmiling, has become eloquent in the School of Materials Science and Technology, and even teases me.
It’s really unexpected that such a junior is joking.”
"Haha, I also found that I have become younger after arriving at the School of Materials Science and Technology." Nie Sen said, "The last time I went back to Pujiang, my old colleagues said that I am very different from the past. Not only have I gained weight,
My mentality is also younger, which is all influenced by the atmosphere of our School of Materials Science.”
"It's better to be younger. Only when you have a young mind can you be energetic." Qin Hai said.
The two of them joked for a while, and Nie Sen asked: "By the way, Mr. Qin, you haven't told me what's going on here. You're not here just for a visit, are you?"
"It's not a bad idea to drop by. Don't Professor Nie welcome me to drop by?" Qin Hai asked.
Nie Sen said: "That's not true. I can't help but ask for Mr. Qin to come to visit me. You can go to the School of Materials and ask if there is anyone who doesn't welcome Mr. Qin to visit you? However, Mr. Qin is busy with everything, so there is nothing he can't do.
Will you drop by casually? Do you want to give us some instructions related to tomorrow's meeting?"
Qin Haidao: "I don't dare to accept the order, but I do have something that I want to discuss with Professor Nie. I don't know if Professor Nie has time."
"I have time, Mr. Qin, just tell me if you have anything to do." Nie Sen closed all the books on the table, sat upright and faced Qin Hai and said.
"Professor Nie, your previous research on ceramic nanocomposites has achieved some results. I would like to discuss with you whether you can leave the subsequent research to your assistant and open up a new research field.
." Qin Hai changed his expression to a serious one and asked.
"Absolutely," Nie Sen said without hesitation. What he was researching was actually quite valuable. If done well, he could produce several very good papers and produce some profitable patents.
However, when Qin Hai asked him to give up, he agreed without saying a word. Based on his experience, he knew that since Qin Hai made such a request, there must be a more important task for him to do, and this task
It is certain that greater achievements can be achieved.
"Mr. Qin, if you have anything to do, just tell me. As long as it's something I can do, I won't hesitate," Nie Sen said.
Qin Haidao: "I have an idea, but I'm not sure whether it can be realized. I want to find an expert with extremely solid theoretical and practical skills to try it. I don't know if Professor Nie is interested. The idea is like this..."
As he spoke, he introduced his ideas about graphene to Nie Sen in detail. Of course, he did not make his words very certain. He just said that he had this conjecture. Based on previous experience, it should be
It can be made. In terms of specific methods for preparing graphene, he also put forward some ideas, including the tape tearing method once used by Geim and others, and the crystal surface epitaxial growth invented by later scientists.
method, chemical vapor deposition method, etc.
While Qin Hai was telling the story, Nie Sen remained silent and immersed himself in taking notes in his notebook. From time to time, he would write down some questions that came to his mind next to the notes. The material preparation methods that Qin Hai mentioned were all Nie Sen's.
Nie Sen was very familiar with it, but he had never thought of using it in the preparation of graphite materials. Qin Hai explained the problem very clearly, and Nie Sen also understood it clearly. He vaguely felt that Qin Hai's idea was very reasonable.
, following this idea, the single-atom graphene material mentioned by Qin Hai is likely to be produced.
As for what kind of properties this material has, Nie Sen couldn't guess yet, but he knew that as long as he had a sample of graphene, performance testing was just a routine operation.
Stable two-dimensional crystal material, this is Qin Hai's definition of graphene, and Nie Sen certainly knows what this means. If this material can be prepared, it means that a law of condensed matter physics will be overturned.
This is an epoch-making discovery. Such a discovery can find a place in top international academic journals such as science or nature, and even winning the Nobel Prize for it is not an extravagant expectation.
Qin Hai placed such a big pie in front of him, how could this not make Nie Sen excited. (To be continued, please search Piao Tian Literature, the novel is better and updated faster!
