Black Technology Refresher Manual

Among the preparation methods of graphene, redox chemical vapor deposition is the most widely used method, but there are few researches on the preparation of graphene by plasma technology.

Sheng Ming'an's team can refer to very few approaches and materials. They almost start from scratch. There are no redundant precedents for reference. They must find suitable and available materials from the vast sea of ​​scientific research materials.

One month after the start of the project, the research progress was stagnant, and many attempts to start ended in failure.

The atmosphere of the team was a bit sluggish. Although they had long been used to failure in scientific research, the difficulty of this challenge was too high, which caused them a lot of psychological pressure.

Repeated failures and no progress in the project really hit their confidence, made them doubt whether the plan was feasible, and questioned whether Sheng Mingan was too stubborn.

Pantry.

The team sat around and discussed, "Actually, I don't? I understand why the boss uses arc plasma to prepare graphene. The thermal plasma generated by arc discharge shows high energy concentration and small volume. How to solve it?"

The person who asked the question was a middle-aged man named Jiao Yuguo.

He is one of the two high-profile talents introduced by Zhang Chao. He has a doctorate from Capital University and has worked on several scientific research projects. His talent and experience are not inferior to Lu Yin's.

He has never read Sheng Mingan's complete plan, so he is quite puzzled.

"The project is too big. In fact, there is no need to go directly to the scale of industrial production. Isn't it better to realize the technology of 12 cm graphene preparation that is not available in the market and master certain skills and proficiency?"

Sun Cheng, one of the former members of Luyin's team: "Dr. Jiao has never heard of Sheng Gong?"

Jiao Yuguo frowned: "I know that Shenggong has conquered the light source technology of high-end lithography machines. He is a genius, isn't he? Fake, but the lithography machine has more than 20 years of national reserves of your technical research, as well as foreign advanced scientific research technology for reference, no? Like graphite ene, which is still a completely new and unexplored field."

Although it is not stated clearly, the meaning is obvious. A new field is in the stage of being explored. Others are carefully exploring step by step. Sheng Mingan is greedy to directly cross to the end.

Sun Cheng: "Dr. Lu is in favor of Shenggong's plan."

Jiao Yuguo shook his head in disbelief how good the plan was: "You don't know the difficulty of industrialized graphene preparation technology."

Sun Cheng was a little uncomfortable hearing this. They didn't have Jiao Yuguo's high education and rich experience, but they had worked in the graphene production industry for several years. How could they not know the difficulty of graphene production technology?

Saying this is too disrespectful to them, as if telling programmers that their job is to fix bugs all day, it is infuriating!

Sun Cheng: "Our previous scientific research project was to overcome the 12 cm graphene preparation technology. Because of the contract signed when we left the company, we could not study this project for at least one year."

Jiao Yuguo expressed regret when he heard the words: "It is also possible to conquer 50 cm graphene."

Another member of the former Lu Yin team couldn’t see it? He pointed it out directly: “Our scientific research project is to industrialize the preparation of graphene, and there are no other miscellaneous goals! You? My job is to complete the work assigned to us by Shenggong. Complete the data records he requested, don't you? You don't need to question Sheng Gong's decision, let alone you? Question the scientific research projects in the laboratory!"

Jiao Yuguo was embarrassed when he heard the words: "I don't? It's a question..."

He pushed another high-profile talent who was also recommended by Zhang Chao, and that person was Fang Zuo.

Fang Zuo is taciturn, and compared to Jiao Yuguo, he looks dull.

He received Jiao Yuguo's hint, and silently turned his head to look at Sun Cheng.

Sun Cheng spread his hands: "If the project leader is your mentor, do you still have so many questions?"

Jiao Yuguo: "How can it be the same—"

Sun Cheng: "The mentor is the boss, and Shenggong is also the boss. What's the difference?" His eyes suddenly became sharp: "In the end, you? Just don't trust Shenggong because Shenggong is young? Or Shenggong's qualifications and education are not enough. , you can't see it in your heart?"

Jiao Yuguo choked, unable to refute.

He really relied on his seniority and the highest academic qualifications, no? Trust Sheng Mingan.It is true that Sheng Mingan is a physics genius, but not to the point of being deified, at least many people in the academic circle are not convinced.

Niu Ruizhi was one of them, and so was Jiao Yuguo.

No? Contrary to Niu Ruizhi's narrow prejudice, Jiao Yuguo was a little in awe of Sheng Ming'an at first, but the lack of scientific research for a month drained his little awe.

Jiao Yuguo: "Anyway, I don't agree with Shenggong's approach. The direction is fundamentally wrong! The international mainstream ideas are radio frequency sputtering and microwave plasma enhanced CVD, and no one uses arc plasma at all. Because the disadvantage of arc plasma is its small size , The parameter gradient is large, and these defects happen to be the bottlenecks that cannot be overcome by the current graphene preparation technology... Fang Zuo, you? Am I right?"

Fang Zuo said slowly, "I think it's better for me to listen to the boss."

Jiao Yuguo almost brought it up in one breath? Come up, he rolled his eyes at Fang Zuo, the idiot is just stupid, and he saw the opportunity to agree at this time? Him!

After Jiao Yuguo's awe of Sheng Ming'an disappeared, he found that Lu Yin's experience and qualifications were not as good as his, so he developed an ambition to seize the dominance of the laboratory.

As long as more than half of the people support him, he dares to take action for his ambition.

Anyway, Sheng Ming'an has already invested tens of millions in this laboratory, and now it's a loss to suspend work for a day. I don't think he dared to bear the risk of brain drain leading to aborted projects, but he didn't expect that Sun Cheng and Lu Yin would be so loyal to Sheng Ming'an !

Jiao Yuguo thought darkly, this group of people are so loyal, but in fact, they are protecting Sheng Ming'an for the sake of money.

Seeing Jiao Yuguo's strange intentions, Sun Cheng became defensive at the moment, and told Lu Yin about it afterwards.

Lu Yin said: "You? Did you do it right? Wrong, I will tell Shenggong later."

After going to work in the afternoon, Lu Yin told Sheng Ming'an about it in the laboratory: "Jiao Yuguo has a lot of thoughts, so we have to guard against him."

Sheng Mingan: "Fire him sometime."

Lu Yin: "There is a shortage of manpower now, can you find a substitute?"

Jiao Yuguo's character is not good, but his ability is worthy of recognition.

Sheng Ming'an: "So wait until we find a substitute, Zhang Chao is still looking for someone."

Lu Yin was silent for a while, and asked, "How about? Explain and stabilize people's hearts?"

Sheng Mingan observed the movement of the graphene, and after thinking about it, he explained what they were researching this month.

"Plasma is the fourth state of matter. Its generation methods include radio frequency sputtering, microwave and arc discharge. Arc discharge generates plasma to prepare graphene..."

The forms of matter are solid, liquid, gas?gas and plasma. Plasma has higher energy than gas?gas and is also a good conductor. Many physical sciences, material synthesis, energy development, etc. It can be realized in the way that the body produces a reaction.

The principle of graphene preparation technology involves plasma. Radio frequency sputtering, microwave and arc discharge are all methods to generate plasma discharge. The first two are the mainstream ideas in the world, and the third method has little related research.

Sheng Ming'an's plan is to choose arc discharge, which will generate a large area of ​​uniform plasma to synthesize graphene.

The 'arc' here is a gas discharge phenomenon, in which electrons and ions are generated, which can also be called thermal plasma, which is widely used due to its advantages of high temperature, high enthalpy, and high chemical activity.

But it is rarely used in graphene preparation.

Because arc plasma has problems such as small volume and large parameter gradient, it limits the development and application of chemical deposition, material preparation and other fields, and cannot realize the preparation of large-area and high-stability graphene.

In other words, the defect of arc thermal plasma happens to be the biggest bottleneck of graphene preparation technology at present!

Hearing this, Lu Yin raised a question: "The thermal plasma generated by arc discharge shows high concentration of energy and small size, which leads to easy burnout of the preparation device, low energy utilization rate, and poor craftsmanship of the finished product, which limits production efficiency. , while affecting the uniformity and stability of the product, how to solve these problems?"

Sheng Mingan raised his eyes: "This is what we have been doing this month."

"...!" Lu Yin suddenly realized: "It turns out that the data you have been collecting has been applied to the arc discharge device. I know you? What do you want to do? I always thought that the data you collected was directly used for graphene preparation!"

Didn't she laugh? Already.

"I suddenly remembered the draft seized by Niu Ruizhi. Even if the data is 100% correct, it is absolutely impossible to realize the technology for the industrialization of graphene."

Because those data are not for graphene preparation technology at all, but for improving the arc plasma device, so as to obtain large, uniform and stable thermal plasma, and indirectly overcome the bottleneck of graphene preparation technology!

Lu Yin rubbed his nose and bowed, "Sheng Gong, your plan is quite roundabout."

Ordinary people will never think of it, but as long as they are awakened, they will find out what a genius the idea is!

Looking at the experiments in her hand and the collected data and images, she sighed in her heart that she had studied graphene for more than ten years, and it was not like a flash of genius.

Sure enough, physics is the domain of geniuses.

With a flash of genius, a world is born.

Lu Yin's melancholy lasted less than a few minutes, and he quickly started collecting the next round of experimental data.

At the same time, Niu Ruizhi of Heijin Technology borrowed ideas from Sheng Mingan's draft, used some data, improved it, and carried out simulation modeling through laboratory software. The result surprised him.

The assistant didn't understand: "Boss, the simulation failed, why are you happy?"

Niu Ruizhi was ecstatic: "You? Didn't you understand? The failure of the simulation is a problem with the data!"

The assistant was surprised: "You mean if the data is correct, the plan is correct?"

Niu Ruizhi expressed ecstasy: "Yes! As long as I find the correct data, I will conquer the industrial graphene preparation technology!"

He is the only one in the world who has mastered the technology of large-scale production of graphene, a technology he has conquered by himself and through untold hardships!

Once he registers the patent and discloses the news, all eyes from the outside world will look at him.At that time, what will fame and fortune and academicians count?Everything is in the bag.

The assistant hesitated while being happy: "What if Sheng Mingan discovers the problem and exposes us instead?"

Niu Ruizhi's face was gloomy immediately, and he stared at him coldly. It was not until his assistant was terrified that he said, "I am the designer of the scheme. I am the one who filled in the wrong data. It is I who conquered this complicated technology. It has nothing to do with Sheng Ming'an." .”

The assistant was shocked: "Boss, I understand!"

Seeing his interest, Niu Ruizhi turned his gaze away, and then worried that Sheng Mingan would realize the value of the plan, and worried that the other party would be the first to disclose the technology, so he hurriedly turned around to find Vice President Huang, and told him his idea of ​​conquering industrialized graphene technology , with excellent eloquence to persuade Vice President Huang to invest.

With the money, Niu Ruizhi started research in a hurry, and with a guilty conscience, in the initial stage of the project, he used the incomplete data obtained and combined with Sheng Mingan's draft to sort out a paper and submit it first.

The paper was published in "PRL (Physical Review Letters)" two months later. Because of the novel idea, it attracted a small amount of attention in the field of physical materials.

At the same time, Applied Materials has also received considerable attention.

Niu Ruizhi, who has not produced any results for a long time, has left his name in the field of material physics with the novel ideas in this paper. King University attaches great importance to the impact of this paper, and will write this paper into Niu Ruizhi's selection of this year's national The academician's personal achievement list becomes one of the bargaining chips.
