Walking out of the main building, Luo Jia and they went to the materials science research center, talking excitedly along the way, there seemed to be a lot to say, recently, he stayed at home to take care of his wife and children, did not participate in the company's experiments and operations, it seems that he was not lightly suffocated.

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

"I'm so nervous, it's been a long time since we made any major breakthroughs since supramolecular carbonaceous materials." Ji Ming quickly took two puffs of cigarette and muttered: "If Cao Yuan's graphene preparation process can be accomplished, 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 come up with a new type of material." ”

Ling Feng laughed when he heard this, "You're still not satisfied?" Prior to this, materials are a well-known major in major colleges and universities, and it is you who have turned the tide and completely changed students' understanding of the future of materials science. ”

Luo Jia nodded, "The more difficult the profession, the more valuable, without the materials science laboratory, we can't even build the shelves of the Kármán vortex street power generation array, and the structure of the ultrasonic motor can't reach the predetermined stiffness, in the whole company, your materials department has always been the best, and everyone knows this very well." ”

An Ran said: "Don't be pressured, materials have always been like this, ten years of hard work to forge a sword, once born, cut the world!" ”

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

I think that the polymer carbon-based materials developed under the leadership of Ji Ming, once they came out, broke the earth, and the shocking complex multi-link structure of the Carmen vortex street power generation array used carbon-based materials, ultrasonic motors, solid honeycomb tires, these epoch-making products, all use derivatives of polymer carbon-based materials.

Relying on its leadership in carbon-based materials, Xingchen Technology is rampant in the electrical and mechanical fields, and the graphene that is about to be tested will make a qualitative leap in the company's material base.

It's like the gap between the Bronze Age and the Black Iron Age, where materials change, productivity and civilization as a whole change dramatically.

Although the Armageddon of Eastern and Western science and technology has come to the city, the people who come to the laboratory today seem to be relatively relaxed, they are the main management of the company, the heads of electrical, optical, mathematical, chemical and other major research centers.

Cao Yuan's graphene preparation test will be carried out under the noses of these super bulls, and accept everyone's harsh questions and questions, even if Cao Yuan passes this audit, next, the brainstorming team will thoroughly verify the possibility of large-scale preparation of graphene from various fields and directions.

"Sure enough, it is the back waves of the Yangtze River that push the front waves, Cao Yuan is only twenty-five years old this year, and he has already achieved such an achievement."

"Chao Anbang of the Superconductor Laboratory is twenty-six years old, and he is also a little guy, Lao Ji is awesome here, it would be good for other research centers to have a successor, he has two."

"Did you leave Mr. Luo behind? It won't be until this summer that Mr. Luo will be twenty-four years old. ”

Hahaha~

Everyone laughed again, Xingchen Technology can have today, relying on talents, the company has nothing, that is, there are many talents!

Through the huge floor-to-ceiling windows of the laboratory, it can be clearly seen that Cao Yuan is preparing with everyone, sitting in the center, scheduling well, and directing the researchers to check the equipment and data.

"Raman spectroscopy imaging test ready!"

"Got it, check the light diffuser below."

Seeing that Luo Jia, An Ran, Li Moran, Zhang Yuechuan, Ling Feng, Zhang Dongning, Wen Chengling, these big bulls in the scientific research community came to the scene, Cao Yuan did not have a trace of panic on his face, he still looked like he hadn't woken up, and used an ink pen to put a check mark on the Raman spectrum, indicating that he was ready.

Raman spectroscopy is a non-destructive analysis technique that provides precise information about the chemical structure, phase and morphology, crystallinity, and molecular interactions of a sample based on the interaction of light and chemical bonds within a material.

Cao Yuan is going to demonstrate today, which may be the most important breakthrough in materials science this century, the large-scale preparation technology of graphene, and when graphene is manufactured, it will be verified with a Raman spectrometer to determine whether it meets the standard.

Cao Yuan checked them one by one unhurriedly, and the general appearance of not waking up was not because of insomnia, but because he had always been like this, in the eyes of geniuses, there was nothing to be nervous about, before going to bed last night, Cao Yuan also played for two hours Taige Lizhichuan and ate a bowl of Master Kong's instant noodles.

In addition to Cao Yuan in this laboratory, there is another existence that makes Luo Jia worry and surprised, he is Ge Quan.

Ge Quan, fourteen years old, a native of Tonghua, Jilin, has an amazing talent for materials science, so together with Shen Lang, Gu Beiyin, Chen Qingyue and others, he became a super genius in the first phase of Xingchen University.

At this moment, this secret experiment, which is about to subvert the global field of materials science, is presided over by Cao Yuan, who was later known as the king of materials, and Cao Yuan's assistant is Ge Quan, who is only fourteen years old.

Time flies, and Star University is growing at an unimaginable super speed.

Elsewhere, fourteen-year-olds are still in junior high school, but at Etoile University, the geniuses are already beginning to emerge, and they are pursuing graduate courses at a young age, and the best of them are deeply involved in the company's major research projects.

Shen Lang is special, he studied under Luo Jia himself, he didn't have a focus on learning, and he learned a lot of messy things, while the other twelve super geniuses now have their own majors and mentors.

Yinghui opened the road of life science research, its teachers are known as ruthless scientists Wen Chengfeng and Wen Chengling brothers, Zhu Xinhong chose the difficult particle physics and nuclear physics majors, under the supervision of the company's two super bulls, Xi Zilan and Xiong Ningyuan.

Anyway, other children are still in their restless adolescence at the age of thirteen or fourteen, and the geniuses of Xingchen University have a clear goal for the future, and work hard for the rise of the Chinese nation.

Luo Jia touched his chin slightly, looked at the twenty-five-year-old Cao Yuan proudly, took the fourteen-year-old Ge Quan, watched Cao Yuan finish the pre-test inspection work slowly, and then scratched a messy hair, looking at the many worried and expectant eyes outside the laboratory.

"What we are going to do today is a large-scale preparation test of graphene." Cao Yuan said in a lazy voice: "As we all know, graphene is an epoch-making good material, but unfortunately, this thing cannot be manufactured on a large scale, according to the current process, it takes more than 1,000 yuan to extract a gram of imperfect graphene." ”

"Please note that this is an imperfect finished product, just like if you buy a pair of pants, the crotch of the pants is torn open, the wind blows, the balls are very cold, but the merchant still asks you to pay more than 1,000 yuan, not because the merchant is black, but because his cost is so high."

Hahaha~

Everyone was amused by Cao Yuan's witty language, and laughed loudly, An Ran couldn't help but laugh: "This trouble, my junior brother has always been very serious, how come he came to the company, he also learned to joke, hey, it seems that there are no rules, it will really be contagious." ”

The biggest feature of Xingchen Technology is that it is free and casual, wearing slippers, COS cartoon characters, as long as the task given to you by the company is completed, Cao Yuan is such a serious good boy, after coming to the company for a long time, he has become eccentric, revealing his inner nature.

"Originally, I also had a headache about this." Cao Yuan continued: "Graphene made by mechanical exfoliation has excellent properties, but the size is so small that it can only be achieved at most 100 microns. ”

"The SIC epitaxial growth method can make a large size, but it requires a high growth temperature of 1,400 degrees, and the graphite oxide reduction method does not require high temperature, and the production is simple, but the finished product has huge defects, and the electrical and mechanical properties are completely unable to meet the standards of the next generation of super materials."

"So, we had to set our sights on the most potential preparation method, CVD chemical meteorological deposition."

Hearing this, everyone's eyes suddenly lit up, and they quickly discussed.

"Could it be that the plasma technology is used to strengthen CVD and grow graphene at relatively low temperatures and non-metallic substrates?"

"If plasma-enhanced vapor deposition is used to prepare graphene, the cost should be much lower, right?"

"Cao Yuan is awesome! The reactants are transferred to the CVD reactor, and the gas precursor is used to react the active species in the gas phase, and then, the precursor and the carbonized active species produced by the reaction are transferred to the substrate by surface adsorption, at this time, the precursor will undergo a surface interface reaction, accompanied by decomposition and the production 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's a genius idea to break down growth into several elemental steps, first the precursor introduction, then decomposition, then nucleation, and finally further growth into continuous graphene sheets."

Li Moran looked embarrassed, he was already stupid, it was worthy of a brainstorming group, Cao Yuan just made a start, these guys have made up so much?

And as a transfer expert, Li Moran couldn't understand the knowledge of chemistry and materials science at all, as if he was listening to a book from heaven, and he didn't know it.

Belch...

Cao Yuan was also dumbfounded, and he hurriedly motioned for everyone to stop.

"Dear teachers and colleagues, that's not the case." Cao Yuan explains: "At the beginning, I did have great expectations for the CVD chemical vapor deposition preparation process, but as the experiment progressed, I gradually found that the vapor deposition method can only make some products at best, but it is far from perfect. ”

"Just when I was at a loss, the company suddenly started the research of ultrasonic motors, and the launch of this super project reminded me that we could not manufacture graphene on a large scale before, could it be the reason for the tool? Ultrasonic motors can achieve nano-level precise control, if this ultrasonic tool is introduced into graphene preparation technology, will a fully automatic production line be made? ”

This guy ditched chemical deposition and used ultrasound as a tool?

When Cao Yuan said this, there was silence inside and outside the laboratory, and everyone seemed to be shocked.
