Technological Supremacy Chapter 385: Brain-opening Cao Yuan’s ultrasonic preparation method!

Out of the main building, Luo Jia and the others went to the Material Science Research Center. Anran talked excitedly along the way, and seemed to have a lot to say. Recently, he stayed at home to take care of his wife and children, and did not participate in the company's experiments and operations. It's not easy to be held back.

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

"I'm really nervous. We haven't made any major breakthroughs since supramolecular carbon materials." Ji Ming took two quick puffs of his cigarette and muttered, "If Cao Yuan's graphene preparation Craftsmanship can be achieved, but materials are difficult to learn. The company has invested so much money, but it takes an average of four to five years before we can produce a new type of material."

Ling Feng laughed loudly after hearing this, "Are you still not satisfied with this? Before that, material was a well-known persuasion major in various colleges and universities. The understanding of the future of materials science, without polymer carbon materials, the company would not be where it is today.”

Luo Jia nodded, "The more difficult the major is, the more valuable it is. Without a materials science laboratory, we can't even build a shelf for the Karman vortex street power generation array, and the structure of the ultrasonic motor can't reach the predetermined rigidity. In the whole company, your materials department has always been the best, and everyone knows this very well."

An Ran interjected: "Don't be stressed, the material has always been like this. After ten years of hard work to forge a sword, once it is born, it will kill the world!"

Everyone laughed. An Ran's words sounded like a chivalrous man. Thinking about it carefully, materials science is the most basic and most important subject in the company.

Thinking about the polymer carbon material developed under the leadership of Ji Ming back then, once it came out, it was earth-shattering. The shocking complex multi-link structure of the Karman vortex street power generation array used carbon materials, ultrasonic motors, and solid honeycomb tires. , These epoch-making products all use derivatives of polymer carbon materials.

A new trick, eating all over the world, relying on its leadership in carbon 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 foundation.

This is like the gap between the Bronze Age and the Black Iron Age. When materials change, productivity and the entire civilization will also change dramatically.

Although the decisive battle between East and West in science and technology has come to an end, the people who came to the laboratory today seem relatively relaxed. principal.

Cao Yuan's graphene preparation experiment will be carried out under the noses of these super experts, and will accept everyone's harsh questions and doubts. In all fields and directions, the possibility of mass production of graphene has been thoroughly verified.

"Sure enough, the waves behind the Yangtze River push the waves ahead. Cao Yuan is only twenty-five years old this year, and he has already achieved such achievements."

"Chao Anbang of the superconductor laboratory is twenty-six years old, and he is also a little guy. Old Ji is awesome. It would be nice if other research centers have a successor. He has two."

"Did you miss Mr. Luo? Mr. Luo won't be twenty-four years old until this summer."

Hahaha~

Everyone laughed out loud again, Star Technology is able to achieve what it is today, relying on talents, the company doesn't have many things, it just has a lot of talents!

Through the huge floor-to-ceiling windows of the laboratory, one can clearly see Cao Yuan leading everyone to make preparations. He sits in the center, dispatches well, and directs the researchers to check equipment and data.

"The Raman spectroscopy imaging test is ready!"

"Got it, let's check the light diffuser."

Seeing that Luo Jia, An Ran, Li Moran, Zhang Yuechuan, Ling Feng, Zhang Dongning, Wen Chengling, all the big names in scientific research came to the scene, Cao Yuan didn't show a trace of panic on his face. As if waking up, I put a check mark on the Raman spectrum item with an ink pen, indicating that I was ready.

Raman spectroscopy is a non-destructive analytical technique based on the interaction of light and chemical bonds within materials, which can provide precise information on the chemical structure, phase and morphology, crystallinity, and molecular interactions of samples.

Cao Yuan is going to demonstrate on-site today, which may be the most important breakthrough in materials science in this century. Up to standard.

Cao Yuan unhurriedly checked them one by one. The appearance of not waking up was not due to insomnia, but he has always been like this. In the eyes of a genius, there is nothing to be nervous about. Before going to bed last night, Cao Yuan played After two hours of Taiko's determination to pass on the story, I ate a bowl of Master Kong's instant noodles.

Besides Cao Yuan, in this laboratory, there is another person that Luo Jia misses and is surprised by, he is Ge Quan.

Ge Quan, 14 years old, from Tonghua, Jilin Province, because of his amazing material science talent, together with Shen Lang, Gu Beiyin, Chen Qingyue and others, became a super genius in the first phase of Xingchen University, known in history as Xingchen Thirteen Taibao.

At this moment, this secret experiment that is about to subvert the global field of materials science is hosted by Cao Yuan, who was later called the King of Materials, and Cao Yuan's assistant is Ge Quan, who is only fourteen years old.

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

In other places, fourteen-year-olds are probably still in junior high school, but at Star University, geniuses have already begun to emerge. They are attacking graduate courses at a young age, and the best of them are still deeply involved in To the company's major research topics.

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

Yinghui started the road of life science research. His teachers were brothers Wen Chengfeng and Wen Chengling, who are known as ruthless scientists. Zhu Xinhong chose the extremely difficult major of particle physics and nuclear physics. Xiong Ningyuan.

Anyway, other children are still in restless adolescence at the age of thirteen or fourteen, and the geniuses of Xingchen University have clear goals for the future, and they are working hard for the rise of the Chinese nation. And their future achievements are equally limitless.

Luo Jia rubbed his chin slightly, looking proudly at 25-year-old Cao Yuan and 14-year-old Ge Quan, watching Cao Yuan slowly complete the pre-test inspection work, and then grabbed Grabbing her messy hair, she looked out of the laboratory with many apprehensive and expectant eyes.

"What we are going to do today is a large-scale preparation test of graphene." Cao Yuan said lazily: "As we all know, graphene is an epoch-making good material, but it is a pity that this thing cannot be mass-produced. With the current technology, it takes more than one thousand yuan to extract one gram of imperfect graphene."

"Please note that this is not a perfect finished product, just like you bought a pair of pants, the crotch was torn apart, the wind blows, the **** are very cold, but the merchant still asks you to pay more than 1,000 yuan, not because the merchant The heart is dark, but his cost is so high."

Hahaha~

Everyone was amused by Cao Yuan's witty words, and they all laughed. An Ran couldn't help laughing and said, "What's the trouble, my junior brother has always been very serious, why did he learn to joke after he came to the company? Hey, it seems that this is not the case. The rules are really contagious."

The biggest feature of Xingchen Technology is that it is free and undisciplined, wearing slippers, COS anime characters, you can do whatever you want, as long as the tasks given by the company are completed. He became weird and weird, revealing his inner nature.

"I was also very troubled by this matter." Cao Yuan continued: "Graphene produced by mechanical exfoliation has excellent performance, but its size is too small. After racking my brains, I can only achieve a maximum of one hundred. Microns."

"The SIC epitaxial growth method can produce large sizes, but it requires a growth temperature of 1400 degrees. The graphite oxide reduction method does not require high temperature, and the production is simple, but the finished product produced has huge defects, whether electrical or mechanical. The performance is not up to the standard of next-generation super materials.”

"So, we had no choice but to focus on the most potential preparation method, CVD chemical vapor deposition."

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

"Is it possible to use plasma technology to strengthen CVD to grow graphene at relatively low temperature and non-metallic substrate?"

"If graphene is prepared by plasma-enhanced vapor deposition, the cost should be reduced a lot?"

"Cao Yuan is awesome! 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 through surface adsorption On the substrate, 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 will diffuse, collide, and combine on the surface, and finally overcome the energy barrier and start nucleation!"

"Oh, I understand what you mean. It is indeed a genius to decompose the growth into several elemental steps. First, the precursor is introduced, then decomposed, then nucleated, and finally further grown into continuous graphene sheets. ideas."

Li Moran showed embarrassment, he was already dumbfounded, as expected of a brainstorming group, Cao Yuan just made a start, and this group of guys have brainstormed so much?

Moreover, as a transfer expert, the knowledge of chemistry and materials science ~IndoMTL.com~ Li Moran also can't understand it at all, as if he doesn't understand it like listening to the scriptures.

Uh...

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

"Teachers and colleagues, things are not like this." Cao Yuan explained: "At the beginning, I did have great expectations for the CVD chemical vapor deposition preparation process. However, as the experiment progressed, I Gradually, I found 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 launch of this super project reminded me that we were unable to manufacture graphene on a large scale before. Could it be because of tools? Ultrasonic motors can To achieve nanoscale precise control, if this ultrasonic tool is introduced into graphene preparation technology, will a fully automatic production line be created?"

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

After Cao Yuan finished speaking, there was complete silence inside and outside the laboratory, and everyone seemed shocked.
