CC, the fastest update material empire!

In the history of scientific history, graphene was found in 2004 from the Geim topical group of Manchester University, and its characteristics are like Qin Hai said that it is a single atomic graphite crystal film.

At that time, GeIM et al. Used a "torn tape method"

To obtain graphene.

They first cut the graphite into thin slices, then stick to both sides of the sheet with a special tape. After the reverse tear open, the sheets are divided into two, and the tape is attached to the two sides.

This process can be repeated, and a thinner graphite sheet can be obtained until a sheet having only one atom thickness is finally obtained, that is, graphene.

After the graphene was discovered, it quickly caused attention to the attention of the materials science and the coagulation physics. About the performance of graphene has become the most popular topics, and the corresponding preparation method research has also achieved breakthroughs, so that the application of graphene become possible.

Graphite has excellent mechanical properties, electrical properties, thermal properties, and optical properties that can be used to construct a variety of high-performance nani devices.

Due to its characteristics of its single-piece structure, graphene can also be used to prepare a carbon-based material having a unique chemistry and electrochemical properties such as various thin film materials, airgel, carbon foam, and the like.

The eyes of merchants are the most kerst, and the graphene has attracted extensive attention in the economic field and is known as "universal materials".

Many countries have invested in developing graphene industries and striving to grab this technology peak that can produce huge benefits.

As a traveler, how can Qinhai not know the value of graphene, but it is only necessary for technology and its own economic strength, and he has no significant potential.

This time, he was attacked by a quiet sentence. He suddenly realized that the timing of graphene research should be mature.

Quiet see Qinhai said serious, and also collapsed the expression of laughter, said: "Qin Hai, do you believe that there is a such material? In my impression, a few professors of Japan, Japan, a few professors have tried After manufacturing single-layer graphite, but did not succeed, the single-layer graphite film they made is completely unable to exist independently, and it will be decomposed soon.

The condensed physics school community has an argument that the 'perfect two-dimensional crystal structure cannot be stabilized at an absolute zero, is you want to break this law? "

Qin Hai smiled: "All the arguments are used to break, you said this law is no exception.

However, you will do this first, or it is good to study your iron-based superconducting.

You can't use it, you don't waste time on other things.

"Still talking to me, do you talk about how much you use it?"

I would rather.

"No, I am in your body, there is absolutely no two.

Qin Hai laughed with a white road.

"Hey, who knows you ..."

Tranquility is very unreasonable for Qin Hai intentional confusion, and then refutes.

But the words were half, she didn't say anything, and the Qin Hai used this topic, it seems sensitive, she still tried to avoid it.

After some encounter in the jewelry store, two people did not continue to go shopping.

Quietly remembered his next day's theme, anxious to go back to the hotel and talk to the mentor Chen Zong again.

Qin Hai is because of sudden thinking of graphene, it is very difficult, and I want to hurry back to the hotel and negotiate with my ministry.

The two called a taxi back to the hotel, together on the building, then their own things are busy.

The tranquility returns the tutorial, and the room to Chen Zongzu went to the final moistener with the tutor.

Qin Hai did not return, and it came to the room of Niesen, the Materials College.

Nie Sen is an expert in Qinhai from the Pujiang, which has some construction trees in the research of nanomaterial performance and preparation method.

This time, he is a "chemical vapor deposition method for preparing Tin / Si3N4 ceramic nano-composite"

Research thesis comes to Paris to participate in the year of materials.

Several ceramic nanocomposites he studied have been invested in production, which has been widely used in automotive engines, electronic components, etc., which have achieved good economic benefits, but also because of this, he is quite Qinhai Visit.

When Qin Hai came to Niesen's room, Nie Sen looked at the academic books that had just bought in the street. He saw that Qin Hai arrived. He was a little surprised, and he quickly got up and smiled. Totary, how come you ... Just now, you are still saying, you and Xiaoning must have a candlelight dinner outside.

"Haha, I can not be so romantic.

Qin Hai sat down on the sofa, smiled and said, "Yes, Nie said, I'm too ignored, the next time we come out again, you should encourage everyone to bring your family, let you drink foreign ink. Professor can take a lady to romance.

Nie Sen has been studying abroad in the early years, so it is a batch of people who have been drinking ink.

I heard Qin Hai said that he smiled and said: "I and my wife is old wife, and romantic.

It is still young and you should be romantic.

We all said that Qin summale Xianing is really a golden child yu, a born one.

Xiaining is so angry, and you will be able to achieve such a big achievement in superconducting research, and Qin has thought of thinking, and there is economic strength. You are together, whether it is life or a career, is a bead joint.

Qin Hai lid said: "For a stop, I found that our Materials College is really a place to exercise, like Professor Your Nie Xi's rigorous, unsmiling university, to the Materials Academy have become said, and will take me This kind of late generation is joking, it is really not to think.

"Haha, I also found that I have gotten it to the Materials Academy.

Nie Sen said, "Last time I went back to the bus, the original colleague said that I have a big difference, not only people are fat, but the mentality is also young, this is the air of our Materials College.

"It's good, you are young, you can have a vitality.

Qin Hai said.

Two people said a few words, Nie Sen asked: "Yes, Qin, you haven't said that I have something here, do you always come casually?"

"The string door has not been tasted, is Did Nie not welcome me?"

Qin Hai asked.

Nie Sen said: "That is not, Qin always willing to come to the door, I have to ask.

You go to the Materials Academy asked, who doesn't welcome Qin to go to the door? However, Qin is always like this, there is nothing, I am afraid that I will not come to the door, is it related to tomorrow's conference, to tell us? "

Qin Haidao: "The command can not dare to be, but it is true that I want to negotiate with Professor Nie. I don't know if Nie teaches.

"I have time, Qin, I have something to say."

Nie Sen took all the books on the table, and the Qin Hai was in danger.

"Professor Nie, the research of ceramic nanocomposites you did now, I have made some results, I want to discuss with you, can you give you a subsequent research to your assistant to do, then open a new research area .

Qinhai changed a serious expression and asked.

"absolutely okay.

Nie San did not hesitate.

What he is studying is actually quite valuable. It is good to make a few very good papers, and can produce some patents.

However, I heard that Qin Hai called him to give up, he didn't say that he had agreed. In his experience, he knew that since Qinhai proposed such a request, it would necessarily have a more important task to give him to do, and this task It must be a greater achievement.

"Qin always, what do you have, just talk, as long as I can do, there is no two words.

Nie Sen Road.

Qin Haidao: "I have an idea, uncertain can not be realized, I want to find an expert in the same theory and practical skills to try it, I don't know if Nie Professor is interested.

This idea is like this ... "

Said, he made a introduction to Nnisen's thoughts on graphene.

Of course, he did not say something very certain, but he said that he had such a conjecture, according to the experience of the former person, it should be possible.

In the specific graphene preparation method, he also mentioned some ideas, including both the tear tape method used by GEIM and others, and also included the crystal surface epitaxial growth method of the later scientists, chemical gas phase accumulation and many more.

During the process of Qin Hai, Nie Sen did not say, burying his head on the notebook, and wrote some questions that he was watching himself next to the record.

The preparation method of these materials said by Qin Hai is Niesen very familiar, but never thought of using it in graphite materials.

Qin Hai said very clearly. Nie Sen also understood that he felt that the imagination of Qin Hai was very reasonable. He died in this idea, Qinhai said the single-layer atom graphene material It is likely to be manufactured.

As for this material, Nie Sen can't guess, but he knows that as long as there is a sample of graphene, the performance test is just some routine operations.

Two-dimensional crystalline materials existing stable, this is the definition of Qin Hai for graphene, Nie Sen certainly knows what this means.

If this material can be prepared, it means that a law of condensation physics will be overthrown, which is the discovery of epoch-making.

Such discovery is to have a place in the international top academic publication such as Science or Nature, and even the Nobel Award is not expected.

Such a big piece of pie, Qin Hai is in front of himself, how can this not let Niens are excited.
