Vol 2 Chapter 511: Give you 1 big pie

In the history of science, graphene was discovered in 2004 by a research group at the University of Manchester in the United Kingdom. Its characteristics are, as Qin Hai said, a single-atomic layer of graphite crystal thin film. ＠ dǐng ＠ ǎn ＠ Xiao Xiao said, ↙. ○. ＄ o At that time, etc. used a "tear tape method" to obtain graphene. They cut the graphite into thin sheets, and then used a special tape to stick the two sides of the sheet. After tearing it back, the sheet was divided into two and stuck to the tape on each side. By repeating this process, thinner and thinner graphite sheets can be obtained, until finally a sheet with only one atom thickness is obtained, which is graphene.
After the discovery of graphene, it quickly attracted the attention of the material science and condensed matter physics circles. The research on the performance of graphene has become the hottest topic for a while, and the research on the corresponding preparation methods has also made breakthroughs, making the application of graphene become possible.
Graphene has excellent mechanical, electrical, thermal, and optical properties, and can be used to build a variety of high-performance nanodevices. Due to the characteristics of its monolayer structure, graphene can also be used to prepare carbon-based materials with unique chemical and electrochemical properties, such as various film materials, aerogels, carbon foams, and so on.
The merchant's vision is the most acute. Once the introduction of graphene, it has aroused widespread attention in the economic field and has been hailed as a "universal material". Many countries have invested in the development of the graphene industry, competing for this technology peak that can generate huge benefits.
As a traverser, how could Qin Hai not know the value of graphene, but was limited by technology and his economic strength in the past few years, and he had no time to take care of this material with great potential. This time, inspired by the ridicule of serenity, he suddenly realized that the time for graphene research should have matured.
Tranquil saw Qin Hai speak seriously. He also put a smile on his face and said, "Qin Hai, are you sure there is such a material? In my impression, several professors at the University of Tokyo in Japan tried to make a single-layer graphite sheet a few years ago, but Without success, the single-layer graphite flakes they made could not exist independently. It quickly decomposed. There has been an assertion in the condensed matter physics community that 'the perfect two-dimensional crystal structure cannot exist stably at non-absolute zero degrees'. Do you Want to break this law? "
Qin Hai laughed: "All the judgments are used to break, this law you said is no exception. Well, you don't have to worry about this matter first, you should still study your iron-based superconductivity Good. You ca n’t dual-purpose. Do n’t waste time on other things.

"Also talk about me, how much use do you have to focus on yourself?" Serenity reprimanded.
"No, I have all my heart on you. Absolutely no use." Qin Hai confessed with a smile.
"Well, who knows you ..." Quietly disapproved of Qin Hai's intentional confusion, he later refuted. However, at the halfway point, she didn't say any more. Regarding Qin Hai's use of this topic, it seemed to be a bit sensitive, so she still avoided it as much as possible.
After some encounters in the jewellery store, the two also lost their minds to continue shopping. Serenity remembered his keynote speech tomorrow. Anxious to rush back to the hotel to discuss with the mentor Chen Zongze. Qin Hai felt itchy because of the sudden thought of graphene. I also want to hurry back to the hotel to talk with my subordinates.
They called a taxi back to the hotel, went upstairs together, and then split up to do their own work. Quietly returned to the room, took the paper, and went to Chen Zongze's room for the final touch-up with the instructor. Qin Hai didn't even return to the room, and went straight to the room of Nie Sen, an expert at the School of Materials.
Nie Sen is an expert that Qin Hai has recruited from Pujiang. There are some achievements in the study of nanomaterial properties and preparation methods. This time, he came to Paris to attend the annual material conference with a research paper entitled "Preparation of n / s3n4 ceramic nanocomposites by chemical vapor deposition". Several ceramic nanocomposites he studied have been put into production in Quwu Ceramics Group, and they have been widely used in automobile engines, electronic components, etc., and have achieved good economic benefits. It is precisely because of this. He is highly valued by Qin Hai.
When Qin Hai came to Nie Sen's room, Nie Sen was looking at several academic books that he had just bought on the street when he was at his desk. He was a bit surprised when he saw Qin Hai coming, and he asked quickly with a smile: "Qin Anyway, why are you here ... everyone said 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, "Yes, Professor Nie didn't say, I really ignored it. We will come back to the meeting next time. We should encourage everyone to bring their families. "Let your great professors who have been drinking western ink take your wife to romance."
Nie Sen had studied abroad in his early years, so he was the group who had drank foreign ink. Hearing Qin Hai saying this, he smiled and said, "My wife and I are old wives and wives, what are they romantic. It ’s you and Xiao Ning who are still young, so they should be more romantic. We all say that Qin and Xiao Ning are really Jin Tongyu girl, a born pair. Xiaoning is so talented that she has achieved such great achievements in superconductivity research at a young age, and President Qin has thought and economic strength. You two are together, no matter Whether it is life or business, it's a marriage. "
Qin Hai repeatedly waved his hands and laughed: "No more, I found that our School of Materials is really a place to train people. A rigorous and unsmiling university student like your professor, Nie, has become able to speak at the School of Materials, and will still take me. Such juniors are joking, it's really unexpected. "
"Haha, I also found that I became younger after I entered the School of Materials." Nie Sen said, "Last time I went back to Pujiang, my old colleagues said that I was very different from the past, not only did people gain weight, The mentality is also young, which is all influenced by the atmosphere of our materials college. "
"It's good to be young, you can have energy if you have a young mindset," Qin Hai said.
The two joked and laughed a little, and Nie Sen asked, "Yes, President Qin, haven't you said anything about me yet? You wouldn't just come here casually?"
"It's not bad to be in the door, isn't Professor Nie not welcome me to go in?" Qin Hai asked.
Nie Sen said: "That's not true. President Qin is willing to come and go. I can't wait for it. You go to the School of Materials to ask who is not welcome to go to the door? I'll come here casually. Is there something related to tomorrow's meeting that you want to tell us? "
Qin Haidao: "Don't dare to take the order, but there is something, I want to discuss with Professor Nie, I don't know if Professor Nie has time."
"I have time, President Qin, you can talk about anything." Nie Sen closed all the books on the table and sat face to face with Qin Hai.
"Professor Nie, the ceramic nanocomposite research you did previously has achieved some results. I would like to discuss with you whether you can leave the follow-up research to your assistants and open up a new research area. "Qin Hai asked with a serious expression.
"Exactly," Nie Sen said without hesitation. What he is studying is actually quite valuable. If done well, he can produce several very good papers, and can also generate some profitable patents. However, when he heard Qin Hai tell him to give up, he agreed without saying a word. Based on his experience, knowing that Qin Hai made such a request, there must be a more important task to him, and this task It must be possible to achieve greater success.
"General Manager Qin, if you have anything, just say it. As long as it is what I can do, there will be no other words." Nie Sen said.
Qin Haidao: "I have an idea, I am not sure if it can be realized. I want to find an expert who has a very solid theoretical and practical skills to try it. I don't know if Professor Nie is interested. This idea is like this ..."
Then, he introduced Nie Sen's ideas about graphene 151. Of course, he didn't say what he was very sure about, but just said that he had such conjectures, which should be able to be made based on previous experience. He also mentioned some specific methods for the preparation of graphene, including both the tape tearing method used by others and the crystal surface epitaxial growth method and chemical vapor deposition method invented by scientists later. Wait ~ EbookFREE.me ~ In the course of Qin Hai's remarks, Nie Sen kept silent and kept a record in his notebook. From time to time, he also wrote some questions that he thought of in a flash of light. Qin Hai said that Nie Sen is very familiar with the preparation methods of these materials, but he never thought that they would be used in the preparation of graphite materials. Qin Hai made the problem very clear, and Nie Sen also heard it very clearly. He faintly felt that Qin Hai's idea was very reasonable. Following this idea, Qin Hai said that the single-layer atomic graphene material It is likely to be manufactured.
As to what kind of properties this material has, Nie Sen couldn't guess at the moment, but he knew that as long as there are samples of graphene, performance testing is just some routine operations.
The stable two-dimensional crystalline material is Qin Hai's definition of graphene. Of course, Nie Sen knows what this means. If this material can be prepared, it means that a law of condensed matter physics will be overturned, which is an epoch-making discovery. Such a discovery can hold a place in international academic journals such as sn or nar, and it is not a luxury to even win the Nobel Prize for it.
With such a big pie, Qin Hai put it in front of himself, how could this not make Nie Sen feel excited. (To be continued ...)
