Technological Hegemony

Walking 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. He seemed to be suffocated. It's not light.

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 cigarettes and muttered, "If Cao Yuan's graphene preparation process can be achieved Well, materials are difficult to learn, and the company has invested so much money, but it takes us four or five years on average to produce a new type of material."

Ling Feng laughed loudly after hearing this, "Are you still not satisfied with this? Before that, materials were a well-known major in colleges and universities, and it was you who turned the tide with your own efforts and completely changed students' outlook on materials science. Without high-molecular 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. , your materials department has always been the best, 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 forging a sword, once it is born, it will kill the world!"

Everyone laughed. An Ran's words were quite chivalrous. Thinking about it carefully, material science is the most basic and most important subject in the company.

Thinking back to the polymer carbon material developed under the leadership of Ji Ming, 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 The products of the company all use the derivatives of high molecular 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 is approaching, the people who came to the laboratory today seem to be relatively relaxed. They are the main management of the company, the heads of major research centers such as electrical, optical, mathematical, and chemical.

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. direction,

Thoroughly verify the possibility of mass production of graphene.

"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 from the superconductor laboratory is twenty-six years old, and he is also a little guy. Lao 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 again, Star Technology is able to achieve what it is today, relying on talents, the company does not have many things, but it has many talents!

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

"The Raman spectroscopy imaging test is ready!"

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

Seeing that Luo Jia, An Ran, Li Moran, Zhang Yuechuan, Ling Feng, Zhang Dongning, Wen Chengling, all the big names in the scientific research field came to the scene, Cao Yuan didn't show a trace of panic on his face, he was still sleepy. Look, put a check mark on the Raman spectrum item with an ink pen, indicating that it is 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, the large-scale preparation technology of graphene, and when graphene is produced, it will be verified with a Raman spectrometer to determine whether it meets the standard.

Cao Yuan unhurriedly checked them one by one. The appearance of not waking up was not because of insomnia, but because he had always been like this. In the eyes of a genius, there was nothing to be nervous about. Before going to bed last night, Cao Yuan played for two hours. Taige aspired to pass it on, and ate a bowl of Master Kong instant noodles.

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

Ge Quan, 14 years old, from Tonghua, Jilin. Because of his amazing talent in material science, together with Shen Lang, Gu Beiyin, Chen Qingyue and others, he became a super genius in the first phase of Star University. .

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 14 years old.

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

In other places, fourteen-year-old children 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 also deeply involved in the company's management. among 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, and learned from two super masters of the company, Xi Zilan and Xiong Ningyuan.

Anyway, other children are still in restless adolescence at the age of thirteen or fourteen. The geniuses of Xingchen University have clear goals for the future and work hard for the rise of the Chinese nation. Achievements are also unlimited.

Luo Jia rubbed his chin slightly, looking proudly at 25-year-old Cao Yuan, and with 14-year-old Ge Quan, watching Cao Yuan slowly complete the pre-test inspection work, and then scratched his messy head. Hair, looking 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, according to the current technology , It takes more than one thousand yuan to extract one gram of imperfect graphene finished product.”

"Please note that this is not a perfect finished product. It's like you bought a pair of pants, the crotch was ripped open, and when the wind blows, the balls are very cold, but the merchant still asks you to pay more than 1,000 yuan. It's not because the merchant has a bad heart. 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: "This is troublesome, my junior brother has always been very serious, how come after coming to the company, he also learned to joke, hey, it seems that there are no rules, really It's 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 company gives you the task is completed, Cao Yuan is such a serious and good boy, he has been in the company for a long time, and he has become old-fashioned. The elf became strange, revealing his inner nature.

"I also had a headache about this." Cao Yuan continued: "The graphene produced by mechanical exfoliation has excellent performance, but the size is too small. After racking my brains, it can only be a hundred microns at most."

"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, regardless of electrical or mechanical properties. It is completely not up to the standard of next-generation supermaterials."

"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 immediately, and they started discussing quickly.

"Is it possible to use plasma technology to enhance 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, right?"

"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 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 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 really a genius idea 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. "

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 just made up so much brainstorming?

Moreover, as a transfer expert, Li Moran couldn't understand the knowledge of chemistry and materials science at all, as if he didn't understand it like listening to the scriptures.

Uh…

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

"Dear teachers and colleagues, this is not the case." Cao Yuan explained: "At the beginning, I did have great expectations for 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 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 achieve nanoscale Precise control, if this ultrasonic tool is introduced into graphene preparation technology, will a fully automatic production line be created?"

This guy ditched 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.
