Chapter 1140 The Birth of the Academic Emperor

At this moment, a hint of understanding flashed across Emperor Yun's eyes. He nodded, then bowed slightly and finally said, "Hello, Teacher Liu."

There is no lack of courtesy, but no respect.

Liu Liu was not stupid, and he quickly said, "Mr. Xiaoqing, actually, we are of similar age, only a few years apart, and we are both young people. From now on, you can just call me Lao Liu."

Well, I’ve already knelt, what’s the point of being taller?
It seemed that the little bastard in front of him was very satisfied with his attitude. A smile appeared on the corner of his mouth, and then he turned his body to the side.
"Brother Liu, you are too polite. Just call me Xiaoqing. Come in and talk."

Liu Liu breathed a sigh of relief, knowing that at least he had not completely messed up in the initial contact.

As soon as he entered the laboratory, Liu Liu felt the charm of money.

Not to mention the huge laboratory space, not to mention the leather sofas and luxurious refrigerators that shouldn't be in a laboratory.

What made Liu Liu drool was that the laboratory was filled with the latest domestic and foreign instruments, some of which he couldn't even name.

In one word, expensive!

Two words: rare!
Three words, very valuable!

Four words: rich and inhumane!
But he still remembered the important things.

Taking out his carefully prepared experimental records, Liu Liu smiled and said, "I have successfully reproduced your data in the experiment of improving the purity of silane by distillation and analysis in the tower bottom of trichlorosilane disproportionation, proving that your theory is correct."

The letter of allegiance must be submitted.

Qing Yun took the experimental record, his eyes quickly scanned the data, and a smile appeared at the corner of his mouth.

He flicked his fingers on the notebook and sighed, "Finally, there's someone who's not so stupid."

Well, he did this on purpose.

I spent more than twenty days working in those laboratories, not for any reason other than to build my own image and enhance my scientific research status.

Even though he has Chen Yiquan, a leading figure in the country's important weapons, standing behind him, and even though he has the scientific research funds to make weapons, it is still wishful thinking for Qing Yun to establish his dominance in this field in a short period of time.

Scientific research has its golden age, scientific research has its genius, scientific research has its young heroes...

However, scientific research status is based on sect relationships, seniority, and who has the whiter beard.

Then the question arises, how does he explain his academic foundation?

No one is a fool, and it cannot be explained. Others will only think that this is the power of capital, and that there is a big boss or big bosses who are willing to do wedding dresses for him under the magic of money.

How can we convince the people like this?

How to do?
We can only take a multi-pronged approach.

The character of a genius and the character of a hard-working person are indispensable.

The most important part is to do things that others cannot do, and to keep doing things that others cannot do.

Use one breakthrough after another to numb others and make them shut up.

Therefore, in this experiment, if Liu Liu had not come to help him prove it, he would have woken up that cheap eighth senior brother Shen Jun in the end.

But Liu Liu's reproduction was even better, saving him a lot of trouble.

On the other side, Liu Liu was left in a state of confusion by Qing Yun's comments.

He knew that his image in Qingyun's heart still needed to be improved.

Although Qingyun's words sounded a bit frivolous, Liu Liu could feel the satisfaction in Qingyun's words.

Well, it is indeed a bit out of place, but when he thought about the fact that more than a dozen laboratories had not been able to replicate this experiment, Liu Liu had to admit that this guy was qualified to say that.

But he also understood that this was a good start. At least Qing Yun gave him a chance to prove his ability.

Liu Liu decided not to dwell on Qing Yun's evaluation, but to focus on the work at hand and demonstrate his professional ability.

Just think of it as listening to a turtle chanting sutras.

Qing Yun didn't seem to notice Liu Liu's psychological drama. He casually threw a notebook to Liu Liu and said, "Record the parameters on the mass spectrometer now."

There was a hint of command in his voice, and he pointed at several other machines in the laboratory.
"Record those parameters at the same time. I need you to process them simultaneously."

Liu Liu's face looked a little ugly. He felt like he was being treated as a handyman in the laboratory.

But he also knew why.

He had been reluctant to look for Qing Yun, probably because he had offended this young master and was now angry with him.

If it were in the past, he would have offended people, so what? Hasn’t he offended enough people?

But after seeing a little bit of Qing Yun's strength, Liu Liu felt that he had to give in.

When it comes to scientific research, it's about talent as well as funding.

No one can predict how outrageous the future achievements of a young man with absolute talent, without any financial constraints and with a bunch of big guys helping him.

Character is shit. Talking about character at this time is sheer stupidity.

The right thing to do is to quickly hold on to this obviously strong thigh and ensure that you have no worries about your research funding.

Liu Liu did everything honestly, just like he did when he was a slave for his supervisor in the laboratory.

He began to carefully record every parameter. Although this work was a bit boring for him, he knew that this was the best opportunity to understand Qing Yun's experimental process.

Qing Yun seemed satisfied with Liu Liu's obedience. He immersed himself in his work, cutting polysilicon with full concentration.

Although Liu Liu was somewhat dissatisfied, he had to admit that he admired Qing Yun's work attitude and professional ability.

It would be impossible to achieve such smooth silicon cutting without twenty years of practice.

Could this guy be some kind of innate holy body?
Half an hour later, Qing Yun threw another pile of data to Liu Liu, "Sort it out and publish a paper in the next few days."

Liu Liu took it and looked at it, looking at him speechlessly: "These... are all process flow parameters."

He actually wanted to curse, what is the scientific significance of this paper? Where is the innovation?
Qing Yun did not stop the work in his hands. He said without turning his head.

"The significance lies in the standard. In the future, the country will uniformly follow this test method for testing."

Liu Liu was stunned for a moment when he heard this.

He wanted to say, what a big face!

But if you think about it carefully, you will understand.

This guy really has a big face.

I heard that all well-known laboratories in the country have received funding from the Semiconductor Development Fund jointly initiated by the Yanhuang Group and the state.

Although this fund is managed by CICC, a central enterprise under the State-owned Assets Supervision and Administration Commission of the State Council, it can ensure the greatest fairness as the fund manager.

However, Yanhuang Group is the largest investor, and anyone with a discerning eye knows that this is why Xiaoqing is always trying to avoid suspicion and give others a reason to criticize him.

At this time, Qing Yun raised his head, looked at Liu Liu and said solemnly, "By the way, publish it in Materials Science and Technology, don't publish it anywhere else."

Liu Liu was stunned when he heard this. He thought for a long time before he remembered what this journal was. Then he asked uncertainly, "Northern Core? Fourth District? What kind of operation is this?"

Qing Yun explained, "It was sponsored by the Ministry of Industry and Information Technology and the Materials Research Society."

At this point, he sneered, "Why should we send our Chinese standards to the international community? Are we going to let them learn from us?"

Apart from anything else, at least in the polysilicon preparation path under the chlor-alkali industrial system, he is the king of this world.

However, these words made Liu Liu speechless.

He is not stupid, his expertise is also in this area, so he knows very well that the method proposed by Qing Yun is indeed world-leading.

But... District 4...

Liu Liu's face turned red.

He wanted to say, he couldn't afford to lose face with this guy!
When he was studying for his doctorate, if he dared to publish an article in Zone 4, his legs would be broken by his supervisor.

Qing Yun squinted at him and asked, "Why, do you think District 4 is embarrassing?"

Well, if Shu University’s “SusMat” or Huating Jiaotong University’s “Nano-Micro Letters” had not been established at that time, he would not want to publish in Zone 4.

It's indeed a bit embarrassing.

But unfortunately, the two domestic journals ranked ahead of "Materials Science and Technology", "Materials Engineering" and "Materials Guide", are only in the third zone, and both have backgrounds in commercial companies, so he is too lazy to get involved.

It is true that Materials Science and Technology is a bit rotten, but it is a national journal with a good pedigree and is suitable for publishing this kind of standard.

What's more...

He said calmly, "Why don't we just carry it to Area 1?"

Anyone who does scientific research knows that if you are unlucky, the journal will be downgraded, and if you are lucky, the journal will be upgraded. The divisions are adjusted dynamically every year.

Liu Liu was so shocked by his words that he was speechless.

But think about it, if all the papers of this so-called Qingyun Laboratory are published in this journal in the future, then it will definitely be ranked first.

Liu Liu continued to work in the laboratory in cooperation with Qingyun, and Qingyun's work efficiency improved a lot because of Liu Liu's assistance.

In fact, Qing Yun was waiting for Liu Liu's arrival. Unlike Liu Liu who knew very little about him, Qing Yun had a much deeper understanding of Liu Liu.

Last year, Fudan University underwent an epic strengthening, absorbing part of the forces from Zhijiang University's School of Semiconductor Materials.

Liu Liu is an associate professor in this college, and his research direction is actually similar to that of his previous life.

There are only slight differences in that his research focuses more on chemical engineering applications, while Liu Liu focuses on chemical engineering theory.

But in the final analysis, the major of chemical engineering is applied science.

Chemical engineering is just chemistry if we take a step back, but if we take a step forward, there is so much more. Chemical engineering is one of the basic industries of modern industry.

In the industrial classification of the industrial structure, the chemical industry is often separated from the heavy industry and listed on a par with the light and heavy industries.

In this way, the industrial structure consists of three major parts: light industry, heavy industry and chemical industry.

Some people often put heavy industry and chemical industry together, calling them heavy chemical industry, as opposed to light industry.

All modern industries with high capital and knowledge content are supported by chemical industry.

Such as electricity, petrochemicals, metallurgy, semiconductors, automobiles, shipbuilding and repair, etc., its products cover a wide market, providing production means and equipment for various industrial sectors of the national economy. It is the "backbone" of a regional economy and a strong material foundation for the modernization of the national economy.

Therefore, if Emperor Yun wants to find someone to assist him in scientific research, Liu Liu's background is the most suitable.

Why not look for other people, or directly find a team of academicians, such as your own school, where those cheap senior brothers are ready-made?

Because Qing Yun couldn't control this group of people.

Because this is scientific research.

We have to explain why we do something, refute theories, and discuss simulations...

This is such a waste of time.

The answer was in his mind. He just needed to reproduce the industry research results of his previous 20 years.

Seniors or other teams who were too old were naturally eliminated by him.

The reason for choosing Liu Liu was, first of all, the relationship. I don’t mean the relationship with the old principal, but his research must be controlled within his own core team.

Academic inbreeding is pure sour grapes. It is an internal tradition and its logic is valid wherever it goes.

High school education is not compulsory, let alone scientific research.

Another reason is human resources or cattle and horse resources.

Even the cheap eighth senior brother Shen Jun couldn't do this.

Because of the job title.

Liu Liu, who holds the title of associate professor, can legitimately conduct research on animals, but Shen Jun, who has not even been promoted to associate researcher through the researcher sequence, does not have this qualification yet, so he can only borrow research animals.

If it’s borrowed, it won’t be very obedient.

In other words, Qing Yun can completely throw a lot of things to Liu Liu's team.

This was the main reason for choosing Liu Liu. Not long after, a voice came from the intercom inside the laboratory, which startled Liu Liu who was sorting out the data.

"Chairman, it's a quarter to ten. You have an appointment with Academician Wang and others for a meeting at ten o'clock."

Qing Yun responded, stopped, turned to look at Liu Liu, "Old Liu, you should go back and rest first, you must have been enduring for a few days."

It would have been better if he hadn't said this. As soon as he said this, Liu Liu's whole body was filled with fatigue. He yawned and shook his head, "If I sleep now, my days and nights will be reversed. Do you have anything to eat? I'll eat something and then stay up late. I'll try to sleep until tomorrow and adjust my schedule."

Qing Yun was also surprised and laughed when he heard this. All scientific researchers are of the same moral character and they did not say anything more about how adjusting to jet lag is harmful to the body.

He knew that Liu Liu was also a single man, and there was nothing wrong with him staying alone since he would be of no use anyway.

He took Liu Liu directly to the lounge next to the laboratory, pointed at the things inside and told him to eat as he pleased. If he didn't like snacks, there was a menu next to him. He could just make a phone call and the kitchen would deliver them.

When Liu Liu saw it, he was happy. He originally wanted to make a bucket of instant noodles.

There are fruits, biscuits, sausages, luncheon meat, beef jerky, all kinds of nuts, and a lot of drinks and snacks, and they are all high-end products.

With all this stuff, who would eat?

He took some as well, "It will be a meeting later, can I listen to it?"

From Qingyun’s attitude today, Liu Liu also understood his position, which was now Qingyun’s scientific research assistant.

This job... Anyone who has studied for a master's or doctoral degree knows what it is about. Liu Liu naturally asked actively with ease.

Just think of it as re-studying for a PhD.

Seeing that he was so sensible, Qing Yun was not polite either, "If you have time, come and listen. It will be good for you."

In a narrow sense, a research assistant is a secretary, but in a broad sense, he is the second boss of the laboratory.

Liu Liu nodded and quickly opened the biscuits and started eating.

Lemon flavor is the fastest to eat.

He is not stupid. In this laboratory, he will have the opportunity to come into contact with the most cutting-edge scientific research trends, and all the people there are big names.

This is undoubtedly a huge opportunity for his career development.

Qing Yun smiled and told him to eat slowly and not to choke. It didn't matter if they went later and it would be okay to let the old men wait for a few minutes.

Liu Liu was just about to say what a shame, but after thinking about it carefully, it seemed to be true.

As a relatively successful young man, he is very clear that he has to protect the face of his old comrades. This is the first iron rule in the workplace. However, he cannot give his old comrades face completely, otherwise he will be taking advantage of his seniority.

As the director of the 'Qingyun Laboratory', Qingyun should respect the old comrades, but it is also understandable that he asks the old comrades to wait when he is busy occasionally.

Well, in this laboratory structure, academicians are not that rare.

A place with dozens of academicians in charge is indeed grand, but when there are too many of something, there is no way to talk about any special status.

But something happened that Liu Liu never expected.

He originally thought that Qing Yun's meeting was a seminar or exchange meeting with academicians.

But now sitting here, he felt like he was in a dream.

How can this be considered a discussion or exchange?
This is just like the 'weekly' irregular group meetings he had when he was doing his doctorate!

Moreover, his cheap student Qing Yun was sitting at the top of the long table in the conference room, like the boss of the laboratory.

Well, he is indeed the big boss. Qing Yun’s title is laboratory director.

But when he saw the academicians reporting their progress of the week to Qingyun one by one, he still felt that this world was too absurd.

All that’s missing is the PPT.

This model is that each academician regards himself as a junior director of the laboratory, and Qing Yun is the senior director who points out the direction.

What made him feel even more unbelievable was that both Qing Yun and the respected academicians in front of him took it for granted.

Not to mention the semiconductor aspect, he could tell that Qing Yun’s direction was very clear.

The development of each link is progressing in a forward sequence, which means that there is foreign advanced experience to refer to.

But this little bastard could meddle in anything related to shipbuilding, which made Liu Liu's eyes twitch.

Qing Yun on the stage concluded at this moment, "Dean Zou, silicon carbide materials have excellent high voltage, high frequency, and high temperature resistance characteristics. I think we can arrange it early and let the people from the Naval Technology Research Institute participate in advance.

These are our fastest and most direct end users, and their needs come first.”

Dean Zou, who was named, smiled happily when he heard this, "No problem, I'll contact Lao Zhang and the others right away.

According to what you said, the bandgap width of silicon carbide material is 3.26eV, compared with 1.12eV of silicon, which allows silicon carbide devices to operate stably at higher temperatures and ensure that our devices will not break down under high-frequency electromagnetic attacks. This will indeed play a huge role in the electronic instrument systems of warships. "

Mr. Wang Yangming, who was sitting on the other side, also nodded and said, "Silicon carbide has a saturated electron drift rate that is twice that of silicon, which results in no current tailing during the shutdown process of its devices, and can increase the switching speed of the components, which is 2-3 times that of silicon.

This makes silicon carbide an excellent choice for electronic devices that require high-speed switching, such as radar systems and communications equipment on warships.”

However, materials science guru Yan Dongsheng frowned at this time, "Silicon carbide is good, but it is very difficult to prepare.

The growth rate is slow, only 2 cm can be grown in a week. The material crystal form is diverse, with more than 200 similar crystal forms. Precise material ratios, thermal field control and experience accumulation are required to prepare defect-free, usable silicon carbide substrates that are all 4H crystal forms at high temperatures.

However, the surface properties of silicon carbide substrates are not sufficient to directly manufacture devices. It is necessary to deposit an additional layer of high-quality epitaxial material on the single crystal substrate and manufacture various devices on the epitaxial layer.

The quality of the epitaxial layer has a great impact on the performance of the device, and the control of defects in the high-voltage field is a huge challenge, and post-processing is very difficult. Silicon carbide is a material with a hardness second only to diamond. The subsequent slicing, grinding, polishing and other processes of the crystal rod are significantly more difficult, and we lack such processing equipment in our country.

Moreover, since the diffusion temperature of silicon carbide is much higher than that of silicon, the diffusion process cannot be used, and only high-temperature ion implantation can be used.

However, after high-temperature ion implantation, the original lattice structure of the material is destroyed and needs to be repaired by high-temperature annealing. The annealing temperature of silicon carbide is as high as 1600°C, which poses great challenges to both equipment and process control. "

The old man kept talking, and after a while he sighed, "It all comes down to the cost issue. I personally think you are too optimistic, Xiaoqing. It will be hard for it to leave the laboratory in three to five years."

As soon as these words were spoken, the whole audience began to talk. Yan Dongsheng's concerns aroused widespread discussion among those present.

Emperor Yun was very pleased that, under his subtle influence, the academicians now looked at issues from a more pragmatic perspective.

However, he would not accept any rebuttal to the question at hand.

In the field of electronic warfare, every tiny technological advantage may become the key to determining the outcome of the battle.

The high temperature and high voltage resistance of silicon carbide materials enable it to withstand extreme electromagnetic environments in electronic warfare and maintain stable operation of electronic equipment.

The time to break through this material must be advanced.

His appearance has accelerated the development of the semiconductor industry.

However, if a country does not have a strong army to back it up and only climbs the technology tree unilaterally, then it will be easiest to be slaughtered like a fat sheep.

What happened in 16 may happen earlier.

If we don't prepare in advance, the one who withdraws might not be America.

National strength must develop in sync with military strength. Sometimes, there is nothing wrong with resorting to aggressive military tactics.

If you can't hold on, everything is just empty talk.

Qing Yun said firmly: "Academician Yan, I understand your concerns. The preparation and processing of silicon carbide are indeed difficult.

But we must see that these difficulties are not insurmountable.

The cost issue needs to be solved iteratively.

Now that we have confirmed its prospects, and through your team, Academician Yan, we have also made certain progress in the preparation technology of silicon carbide, then we will move forward with determination.

I believe that as our industry’s own technology continues to advance, these problems will be solved one by one.”

"As for equipment, the Ministry of Industry and Information Technology is currently investigating the situation. I believe that the public still has some wisdom. At the same time, we are also introducing some high-end equipment from abroad through the glass industry.

But I still say that if domestic products can be used, use them. It doesn’t matter if the performance is slightly worse, as long as we can iterate, and within our capabilities, we will provide soil for the growth of domestic products.”

"Silicon has a high theoretical specific capacity and low lithium insertion potential, which is close to the theoretical specific capacity of lithium metal anodes. According to the calculation of forming Li3.75Si alloy, its theoretical gram-specific capacity reaches 3579mAh/g, which is close to 10 times the theoretical capacity of commercial graphite anodes.

In addition, silicon exhibits a lithiation/delithiation voltage of approximately 0.4 V, which is lower than most other alloy-type anodes and can provide higher energy density.

At the same time, its working potential is slightly higher than the lithiation potential of graphite, which can greatly avoid lithium precipitation and improve cycle life and safety.

It will inevitably become the negative electrode material."

"Professors Wang Juan and Zhang Xianglan from our School of Chemical Engineering have conducted in-depth research in this area. At the same time, Gong Jun and others from the School of Mechanical and Electrical Engineering of Hubei University of Science and Technology have also conducted some research on silicon-based negative electrode silicon source materials for lithium-ion batteries and their preparation processes.

We should have a consensus on this. Silicon-based negative electrode materials are considered to be one of the promising negative electrode materials for the next generation of lithium-ion batteries due to their high specific capacity, but they also face commercial barriers such as cost and volume expansion, which prevent them from leaving the laboratory. "

"Money is meant to be used. The development fund can support these two teams..."

"If one way doesn't work, try another. Since the rigid strategy doesn't work, why not switch to viscoelastic? Wouldn't that solve the problem of stability of the high expansion negative electrode?"

"There's no buts. I don't want you to prove whether my theory is feasible. I want you to realize it. It's that simple!"

Liu Liu was stunned by the way Qing Yun got along with the academicians.

He knew very well that these academicians were not kind-hearted old men with white beards.

The principle of 'a kind man cannot command an army' is also applicable to the management of scientific research teams.

However, at this moment, Qing Yun behaved like a tyrant in the laboratory, and his words were filled with unquestionable decisiveness.

"I don't need you to tell me this plan won't work, I need you to find a way to make it work!"

Qing Yun's voice echoed in the conference room, and his eyes were firm and sharp, as if he could see through the soul of every participant.

“If everyone only does the obvious things, then what is the difference between us and those mediocre labs? What we want to do is breakthrough, innovation, and be at the forefront of science and technology!”

Every word Qing Yun said was like a hammer, hitting everyone's heart hard.

No one dared to object as long as it was Qing Yun's rebuttal, even if what Qing Yun said seemed a bit too much in his ears. Although those academicians looked unhappy, they still maintained an attitude of respecting the decision.

This left Liu Liu puzzled.

But as the meeting progressed, Liu Liu gradually understood.

This is not the power of money, but the authority of academics.

All the ideas proposed by Qingyun in previous group meetings have achieved gratifying interim results, and he has proved his correctness with facts.

The academicians respect Qing Yun not only because of his title, but also because of his talent and vision.

They saw the potential and possibilities behind the plan proposed by Qing Yun, and they were willing to follow and invest in this potential and possibility.

As the meeting continued, Qing Yun put forward specific and clear requirements for each project. Each of his questions hit the nail on the head, and each of his suggestions was constructive.

The academicians took notes and discussed seriously, their eyes filled with enthusiasm for their common cause.

Liu Liu sat aside, observing all this silently, his heart filled with complicated emotions.

It seems so unreasonable!

It is impossible for people to be born with knowledge. How can a teenager who is only three months away from turning 19 have his own unique insights in so many chemical fields and be so well aware of the direction of cutting-edge technology?

The most amazing thing is that he can always find the most suitable path among the complicated technical routes.

You have to know that many routes are not right or wrong, but whether they are suitable for the current productivity.

How could he see through the essence at a glance?

But Liu Liu couldn't clearly explain what was unreasonable.

Qing Yun's various characteristics make all these unreasonable things reasonable in the end.

Talent, hard work, energy, practice...

There is also the power of capital.

Almost all the route disputes were resolved by Qing Yun's prodigal behavior of skipping the simulation test and going directly to the experimental test.

Sitting on a chair in the outer circle, looking at the young man at the top of the long table, Liu Liu felt as if he was witnessing the birth of an academic emperor who was unprecedented and would never be succeeded in ancient and modern times, both in China and abroad.
