Chapter 385: Cao Yuan's Ultrasound Preparation Method with Big Brain Hole!

Out of the main building, Luo Jia went to the Material Science Research Center and talked excitedly along the way. There seemed to be many things to say. Recently, he stayed at home to take care of his wife and children. Not too light.

Outside the Materials Research Center, Luo Jia met Ji Ming and Ling Feng who were standing in the corridor and smoking.

"I'm so nervous. We haven't made any major breakthroughs in a long time since the supramolecular carbon materials." Ji Ming quickly smoked two cigarettes and muttered: "If Cao Yuan's graphene preparation process can be achieved Well, it is difficult to learn materials. The company has invested so much money, but it will take an average of four or five years before we can produce a new type of material. "

Ling Feng laughed after listening, "You are not satisfied with this yet? Before that, the materials were the famous dismissal majors of universities and colleges. It was your own efforts to turn the tide and completely change the prospects of students for materials. It is recognized that without high-molecular carbon materials, there would be no company today. "

Luo Jia nodded. "The harder the specialty is, the more valuable it is. Without the material science laboratory, we can't even mount the shelves of the Carmen Vortex Street Array, and the structure of the ultrasonic motor cannot reach the predetermined rigidity. , Your materials department has always been the best, and everyone knows this very well. "

An Ran interfaced: "Don't be under pressure. The materials have always been like this. After ten years of hard work, the sword will be born and the world will be cut!"

Everyone laughed, Enron's words were quite knight-like, and if you think about it, materials science is the most basic and most important discipline of the company.

Imagine the high-molecular carbon materials developed under the leadership of Ji Ming at that time. Once they came out, the world ’s astoundingly complex multi-link structure of the Carmen Vortex Street Array used carbon materials, ultrasonic motors, and solid honeycomb tires. All products use derivatives of high-molecular carbon materials.

Taking advantage of the leading in carbon materials, Xingchen Technology has taken the lead in the field of electrical and machinery, and graphene, which is about to be tested, will make the company's material foundation a qualitative leap.

This is like the gap between the Bronze Age and the Black Iron Age. Materials have changed, and productivity and the entire civilization have changed dramatically.

决 The decisive battle between East and West science and technology. Although it is already on the battlefield, the people who come to the laboratory today look relatively relaxed. They are the company's main management, the heads of the major research centers of electricity, optics, mathematics, chemistry and so on.

Cao Yuan's graphene preparation test will be carried out under the eyelids of these super big cows, and accept everyone's harsh questions and questions. Even if Cao Yuan passed this review, the brainstorming team will also have to choose from various fields and various aspects. Direction to thoroughly verify the possibility of mass production of graphene.

"Sure enough, it is the waves behind the Yangtze River that push the waves forward. Cao Yuan is only 25 years old this year, and he has already achieved such achievements."

"Chao Anbang of the Superconductor Lab is 26 years old, and he is also a little guy. Lao Ji's side is superb. It is good for another research center to have a successor. He has two."

"Did you miss President Luo? By this summer, President Luo will be 24 years old."

Oh ha ha ha ~

Everyone laughed again. Star Technology can be as it is today. It depends on talents. The company has nothing but talents!

Through the huge floor-to-ceiling window of the laboratory, we can clearly see that Cao Yuan is taking everyone to prepare. He is sitting in the center of the town, has a good schedule, and directs the researchers to check the equipment and data.

"Raman spectroscopy imaging test is ready!"

"Yes, let's check the light diffuser."

Seeing Luo Jia, Enron, Li Moran, Zhang Yuechuan, Ling Feng, Zhang Dongning, Wen Chengling, all the bulls in the scientific research community came to the scene. Cao Yuan did not wake up with a trace of panic, or the one who did not wake up It looks like a check mark on the Raman spectrum with an ink pen, indicating that you are ready.

Raman spectroscopy is a non-destructive analysis technique based on the interaction of light and chemical bonds in materials. It can provide accurate information about the chemical structure, phase and morphology, crystallinity, and molecular interactions of a sample.

Cao Yuan will perform a live demonstration today. It may be the most important material science breakthrough of this century. The large-scale graphene preparation technology will be verified by Raman spectroscopy to determine whether it is up to standard.

Cao Yuan checked one by one without hesitation. The general appearance of not waking up was not because of insomnia, but he always did. In the eyes of genius, there was nothing to be nervous. Before going to bed last night, Cao Yuan also played for two hours. Taige determined to pass on a bowl of Master Kong instant noodles.

In addition to Cao Yuan in this laboratory, there is another one that makes Luo Jia remember and is pleasantly surprised. He is Ge Quan.

Ge Quan, fourteen years old, from Jilin Tonghua. Because of his amazing talents in materials science, he, together with Shen Lang, Gu Beiyin, Chen Qingyue, and others, has become the super genius in the first phase of Xingchen University. .

At this moment, this secret experiment that is about to disrupt the global field of materials science is hosted by Cao Yuan, who later became known as the King of Materials, and Cao Yuan's assistant is Ge Quan, who is only 14 years old.

As time flies, Star University is growing fast at an unbelievable speed.

Elsewhere, 14-year-olds are still studying in junior high school, and at Xingchen University, geniuses have begun to emerge. They are attacking postgraduate courses in a small grade. The best of them are also deeply involved in the company. Among major research topics.

Shen Lang is special. He studied under Luo Jia himself. He didn't focus on his studies. He learned a lot of mess. The remaining 12 super geniuses now have their own majors and mentors.

Tong Yinghui started the life science research path. His teachers were the brothers Wen Chengfeng and Wen Chengling, who are known as fierce scientists. Zhu Xinhong chose the particle physics and nuclear physics majors that are difficult to overcome. He taught the company's two super big cows, Xilan Lan and Xiong Ningyuan.

Anyway, other children are still agitated during their thirteen years. The geniuses of Xingchen University have clear goals for the future and work hard for the rise of the Chinese nation. It is by no means empty talk here, and they will The achievements are equally limitless.

Luo Jia touched his chin slightly and looked proudly at 25-year-old Cao Yuan, with 14-year-old Ge Quan, and watched Cao Yuan Mo Mochi finish the pre-examination inspection, then grabbed a mess He looked forward to the many gazing and expectant eyes outside the laboratory.

"What we are doing today is a large-scale preparation test for graphene." Cao Yuan sounded lazily: "As we all know, graphene is an epoch-making good material, but unfortunately it is not an egg. There is no way to make this thing on a large scale. According to the current process It takes more than a thousand yuan to extract one gram of imperfect graphene finished product. "

"Please note that this is an imperfect finished product. It's like you bought a pair of pants, the crotch is torn apart, the wind blows, the eggs are very cold, but the merchant still asks you to pay more than one thousand yuan, not because the merchant's heart is dark, It's because he costs so much. "

Oh ha ha ha ~

Everyone was amused by Cao Yuan's funny language and laughed a lot, and Enran could not help but said: "This is noisy, my teacher and brother have always been serious, how to come to the company, they also learned to joke, hey, it seems that this is unruly, really Is contagious. "

The biggest feature of Xingchen Technology is that it is free and casual, wear slippers, COS anime characters, and toss as much as you want, as long as the task given to you by the company is completed, Cao Yuan has been a good-looking child. He has been in the company for a long time, and it has become ancient. The spirit blame, revealing the nature of the heart.

"I had a headache this time, too." Cao Yuan continued: "The graphene produced by mechanical peeling has excellent performance, but the size is too small, and the brain can only reach 100 microns at most."

"The SIC epitaxial growth method can make large sizes, but it requires a growth temperature of 1400 Baidu. The graphite oxide reduction method does not require high temperatures, and the production is simple, but the finished product has huge defects, both in electrical and mechanical properties. It's completely substandard for the next generation of super materials. "

"So, we had to look at the most promising preparation method, the CVD chemical meteorological deposition method."

When I heard this, everyone suddenly lighted up and discussed quickly.

"Is plasma CVD enhanced to grow graphene at relatively low temperature and non-metallic substrate conditions?"

"If plasma enhanced vapor deposition is used to prepare graphene, the cost should be reduced a lot?"

"Cao Yuan Niubi! Transfer the reactants to the CVD reactor, use the gas precursor to react the active species in the gas phase, and then transfer the precursor and the carbonized active species produced by the reaction to the substrate by surface adsorption. At this time, the precursor will undergo a surface interface reaction, accompanied by decomposition and the generation of the final active species, the active species diffuse, collide, and combine on the surface, and finally overcome the energy barrier and start nucleation! "

"Oh, I see what you mean. It is a genius idea to decompose the growth into several element steps, first introduce the precursor, then decompose, then nucleate, and finally grow into a continuous graphene sheet. "

默 Li Mo was embarrassed. He was stupid. He was a brainstorming team. Cao Yuan just opened his head. Did these guys make up for so much?

Also, as a transfer expert, she has professional knowledge in chemistry and materials science ~ EbookFREE.me ~ Li Moran also does not understand at all, as if listening to Tianshu, she is unclear.

Uh…

Cao Yuan was also dumbfounded, he quickly motioned to everyone to stop.

"Teachers and colleagues, this is not the case." Cao Yuan explained: "In the beginning, I did expect great things about the CVD chemical vapor deposition process. However, as the experiment progressed, I gradually discovered that The vapor deposition method can only produce some products at the highest level, but it is far from perfect. "

"Just when I was at a loss, the company suddenly started research on ultrasonic motors. The start of this super project reminded me that we were unable to manufacture graphene on a large scale before. Is it a tool? Ultrasonic motors can achieve nanoscale Precise control. If this ultrasonic tool is introduced into graphene preparation technology, will it produce a fully automatic production line? "

This guy abandons chemical deposition and uses ultrasound as a tool?

曹 After Cao Yuan said this, everyone inside and outside the laboratory was silent, and everyone seemed shocked.
