Chapter 1308

Yun Fei saw that Luo Weilin and Mi Wanqing were here.

Yun Fei is very clear about the virtues of these two guys. They have always wanted to develop Guocheng into an industrial city like Chengdu and Shancheng. At present, Jiuyi materials and Jiuyuan have become their development support.

Therefore, these two guys even have an almost flattering attitude towards Yun Fei.

Yun Feidao also understands this matter. After all, Guocheng does not have the unique geographical conditions as other coastal cities, and various location factors are not too obvious. Although it is close to the Jialing River, the water transportation conditions are not very good.

This year, only when the economy develops can officials have political achievements.

The settlement of such a huge enterprise as Jiuyi material factory in Guocheng has a huge role in promoting and driving the economy of the whole Guocheng.

"Secretary Luo and mayor MI are so idle?" Yun Fei's words are not without ridicule. He is really not very cold about such a situation. In particular, Luo Weilin and Mi Wanqing have nothing to do with their cooperation this time.

Luo Weilin naturally knew Yunfei's temper. They had the cheek to come here, so there was no embarrassing reaction when they heard Yunfei's words. The 91 materials should cooperate with the Chinese Academy of Sciences and military scientific research institutions. These things are a very good opportunity for them in Guocheng.

As long as these cooperation results, they will definitely invest in the construction of factories in the end. As long as they can win it, how big a political achievement must it be?

After the two sides exchanged greetings, they didn't chat too much and went straight to the Jiuyi material factory.

"This is the most top constant temperature and dust-free laboratory in China with the best environment built by our company with an investment of 180 million in the first half of last year. The equipment inside is the top equipment from Europe. At present, there is no better material laboratory in China than ours... "Guo Chuan had no opinion on the arrival of the delegation from the Chinese Academy of Sciences and the Commission of science, technology and industry for national defense, and calmly introduced the situation in the laboratory.

"Director Guo, I heard that you have been studying graphene for several years. I wonder if you can introduce it to us now?" Huaqing naturally wants to go straight to the theme. The high-temperature alloy production workshop of Jiuyi materials and the production of various cutting tool materials and even the post-treatment process workshop are not attractive to them.

What they need to know is the situation of graphene, a two-dimensional material that the outside world believes cannot exist independently.

This thing is so useful. It plays a very powerful role in promoting a country's science and technology system. Only by knowing the progress of 91 materials in this regard, the people brought by Huaqing and Zhao Xingbang will know where they should start.

"It has been carried out for several years, but theoretical research has been carried out before. Due to improper methods, graphene in complete form has not been obtained. At the request of our boss, Mr. freight, we peel the graphite sheet from the graphite according to the method provided by him, then stick both sides of the sheet to a special tape, tear off the tape, and then we can divide the graphite sheet into two. They kept doing this, so the flakes became thinner and thinner. Finally, they got a flake composed of only one layer of carbon atoms, which is graphene... "Guo Chuan said here, staring at Yun Fei with admiration.

He really can't figure out how Yunfei, who basically doesn't know much about materials, put forward such a simple method in this regard and made them achieve great results. If such a thing is said, no one will even believe it.

"Director Guo, this is modesty. I just said it casually. I don't understand anything at all. " Yun Fei was a little embarrassed when he saw that everyone had focused on him.

This is also due to his interest in these advanced technologies when he wandered around the Internet. Although he can't know the detailed processes and methods, he can probably write them down. For him, these things are a material that can boast to people. But for professional researchers, such a simple thing is absolutely enlightening!

With some brief memories provided by Yunfei, Guo Chuan's team has made rapid progress in this regard, and even has not been far from entering the field of industrial production.

"After the development of graphene, we began to look for the preparation method of large-scale industrial production and carried out research in the application field with colleagues from the Institute of electronics. A month ago, we successfully manufactured graphene planar field effect transistors and observed the quantum interference effect. Based on this result, we developed circuits based on graphene... "Guo Chuan said to the giants of various disciplines while slowly moving forward in the laboratory with everyone.

Hearing Guo Chuan's words, those who have studied materials science are shocked.

The research of Jiuyi material factory in this field has completely reached the stage that it is about to enter the field of industrial production. They have joined in at the moment. They have nothing to do except to conduct large-scale application and Development Research on this material that does not exist abroad.

"So your research on this has been a success?" Hua Qing was followed by an old man with gray hair and thick eyes like the bottom of a beer bottle. He asked incredulously.

This is incredible.

This is a newly built laboratory!

In such a short time, what means did they use to produce circuits based on graphene? Are you kidding?

"This is far from success. This is just the beginning. Besides, it is impossible to apply this material to the field of chip production. Our research equipment limits our research progress. Fortunately, the boss has solved these problems for us... "Tax Ruijun flattered Yunfei and introduced them to the public.

The laboratory is not a concrete building, but a huge factory building. It is made of light steel structure. It has two floors. The lower floor belongs to material research, while the upper floor belongs to electronic research laboratory. The most important cutting tool materials of 91 materials are not here except the nano materials used for coating. This building is an independent research and experimental building.

Due to the heavy graphite dust, it is easy to pollute the air. Therefore, in the research area of graphene preparation process, many places are divided into small areas by transparent glass.

"So far, according to the boss's description, whether it is prepared by mechanical or chemical methods, the cost is very high, and the production efficiency can not reach the degree of large-scale production. At present, we mainly use silicon carbide particles as raw materials to obtain high-quality unsupported graphene materials through high-temperature pyrolysis. The structure and size of graphene can be controlled by controlling the raw silicon carbide particles, pyrolysis temperature, rate and atmosphere. At present, this process is not very mature, and the graphene produced in the laboratory every day is not enough for us to study and use... "Every time Guo Chuan said, the old experts behind him turned black.

That also means cooperation.

People have reached this level. How can they be so kind and brazen to talk about cooperation here? Even if they are experienced, they are absolutely unfamiliar with new materials such as graphene. Can people agree to learn from scratch?

Seeing those transparent graphene sheets in the laboratory, even thinner than ordinary plastic bags, and those chips only the size of fingernails, these are not finished products, not even semi-finished products. They can only be regarded as failed test products. What else can they do except stunned?

In particular, most of the researchers here are young people in their twenties and thirties. They can't imagine that this is the birthplace of the world's top materials!

Moreover, they can't imagine that the work being done by these young technical researchers will affect the whole world and even replace silicon-based chips!

How crazy the world is!

"Mr. Yun, your 91 materials are going to surpass the rhythm of your group company! When can these technologies be invested and built? How much land do you want? We are ready to prepare in advance... "After the visit, the leaders of Guocheng, who didn't say a word all the way, hurried to make a statement to Yun Fei.

They didn't understand Guo Chuan's professional introduction at all, but they listened to the comments of old experts from the Chinese Academy of Sciences and the military.

Nine one materials are going to fly.

How can such an opportunity not stay in Guocheng!

Even if future generations come to enjoy the cool, others will remember that they left this project in Guocheng.

"These eight characters haven't been written yet. Don't worry, Secretary Luo. If I really want to invest in building a factory, I won't mind bothering you. I hope you won't bother me too much at that time. Moreover, granting me land now has a great risk... "Yun Fei smiled and said to Luo Weilin.

"Dean Hua, what do you think?" Zhao Xingbang's heart was very heavy. He didn't expect that Yunfei's confidentiality work was so good. Now they are a little cheeky if they want to join in. They really can't do these things.

Even if they join, they will not have a strong driving effect on this material in a short period of time
