It is simply impossible for one person to complete this kind of knowledge. If only the people with this kind of knowledge are nothing to Xia Guo, a large number of people can be transferred in minutes.

But the key difficulty is that the aero-engine cannot give a detailed description theoretically. This is like Schrödinger's cat. Before opening the box, the cat may be dead or alive. Only after you open the box can you know the cat. Is dead or alive.

Aeroengines are like this, which can only be verified through a large number of experiments.

It takes at least several decades for an engine to go from project approval to mature application. The F22 engine took 32 years from project approval to operational capability, of which it took 31 years for the experiment and cost nearly [-] billion dollars.

The Taihang engine took 27 years, and the Emei time was even shorter.

To be able to get the engine under the conditions of not being rich and industrially backward decades ago is already so awesome that it has taken off.

Even though Chen Nuo has a system now, he never thought of researching aero-engines, it's too fucking time-consuming.

The second difficulty is to operate under the conditions of high speed, high temperature, high pressure and complex force, and also to take into account the requirements of light weight, small volume, long life and reusability. These conditions have multiplied the difficulties geometrically. .

But Chen Nuo's alloy steel has basically solved this problem, even far surpassing foreign countries. After all, the melting point of alloy steel is 2800 ℃, and the temperature of the engine combustion chamber is 1700 ℃, which cannot cause any damage to alloy steel at all. Damage, in theory, can be used forever.

Moreover, the density of alloy steel is much lower than that of titanium alloy, nickel-based alloy, chromium-molybdenum-vanadium alloy steel, etc. Under the same thrust, the speed will be faster and more flexible.

I suggest that you take three steps side by side. The first is to use the current alloy steel to replace the J10 and 20 that are already in service to improve the performance of the fighter.

The second is to build a part of the entire fighter with alloy steel;

The third is to fully promote the Tiangong project. Resources can be more inclined. High-precision machine tools are the foundation of all industries. High-precision machine tools plus my alloy steel can more than double the performance of both Taihang and Emei. .

As long as the pilot's physical fitness can keep up, he can hang the F22.

Speaking of this, Chen Nuo became a little excited. He really wanted to see the J20 made of alloy steel.

Chapter 471 One thought of heaven, another thought of hell

Chen Nuo mercilessly rejected Zhou Zhengfeng.

If he wasn't still in the car, he would have kicked the guy down.

Professor Chen, I'll be back in the city soon and I'll treat you to dinner!

No, I'm afraid you'll sell me out.

Chen Nuo responded firmly.

He was really afraid that this guy would make any more demands that would make him tremble with fear.

But he still wanted to find some time to go to Chengfei and wait for a few aviation research institutes to check in and see if he could get information on aero engines. This could be considered a tricky way.

After returning from the garrison area, Chen Nuo had nothing to do.

During the day, I guide students to do research in the Huaqing office, and go home to spend time with my family after get off work.

What made him happy was that Luo Qingshi's fractured left arm had almost recovered, and it would be almost healed in a week.

Professor, my research topic has produced the first phase of results!

On this day, when Chen Nuo was instructing Shen Min and Jiang Shuai on their projects in the office, the door suddenly opened.

Wei Feng walked in.

So fast?

Chen Nuo asked in surprise, and then said: Show me.

Wei Feng's research is on the subject of nano-dot perovskite, which is half of the reason why he recruited Wei Feng.

Nanodot perovskite has the characteristics of giant magnetoresistance, high ionic conductivity, and catalytic effect on oxygen evolution and reduction.

It can be used in catalysis, storage, sensors, light absorption and other fields.

Wei Feng took out a stack of documents from his backpack and handed them over. Chen Nuo took the documents and opened the cover.

[Application of perovskite nanocrystals/quantum dots in solar cells]

This topic was determined after they started the topic together.

Chen Nuo looked slowly, while Shen Min poured Wei Feng a glass of water to calm his excitement, and Jiang Shuai pointed out.

The two of them slowly retreated outside.

Jiang Shuai looked at Wei Feng: Crazy, awesome, waiting for your treat.

Brother Feng, you are about to gain both fame and fortune.

Shen Min was also chatting at the side.

I'm so envious, why don't you transfer to the Department of Materials Science and Technology, the professor will agree, and I, Senior Brother He and Xiaoxiao can give you extra lessons, and three Ph.D. tutoring lessons, you will make a lot of money.

Wei Feng is no longer as dull as usual because of the results.

Forget it, I'm also a big brother of Professor Chen's line of mathematics, what to say if you go to the line of materials!

Jiang Shuai, didn't you agree that I'm the elder sister?

Shen Min at the side was a little dissatisfied.

The three communicated in low voices.

In the office, Chen Nuo flipped through Wei Feng's thesis, which was divided into three parts.

The first is to describe the crystal/electronic structure, optoelectronic performance and stability, and the synthesis method of CHPNCs/QDs, followed by the application as active layer, interfacial layer, additive and energy transfer layer in solar cells.

The third part is the stability challenge of CHPNCs/QDs, and a simple outlook on the possible development direction of CHPNCs/QDs in future solar cell applications.

Because it was guided by Chen Nuo, it seemed very fast. After more than half an hour, he finished reading the paper.

Then I turned to the data statistics part of the thesis. After looking at the assembly of perovskite photodetectors, the light multiplication coefficient was as high as 10 to the fifth power, and the photoelectric conversion rate reached 34%, I was full of emotion.

The photoelectric conversion rate is 5 percentage points higher than that of materials currently on the market. 5 percentage points may not seem like much, but it would be terrifying if used in the country's photovoltaic power generation.

Last year's photovoltaic power generation accounted for 2.2% of the total power generation, totaling about 1700 billion kwh, and an increase of 5% was an increase of 85 billion kwh.

According to the cost of 0.5 yuan/kWh, this is 42.5 billion yuan.

But photovoltaic power generation is far more than just power generation. It saves a lot of coal resources and reduces a lot of emissions, which is immeasurable to the environment.

He is very happy that the students are promising.

Come in!

Chen Nuo shouted towards the outside.

The three who heard Chen Nuo's cry entered the office, and seeing Chen Nuo sitting at the tea table, Shen Min hurried forward to make tea.

Sit down!

Chen Nuo greeted him, and then said, "Wei Feng, it's very good to be able to do this in a short period of time."

After everyone sat down, he took the tea from Shen Min and said, "Wei Feng, I read the paper, it's very good, I'll polish it up, it's fine to publish it on Nature Materials."

Professor, let me publish it in the material section of the origin journal!

Wei Feng quickly responded.

you sure?The original journal materials section is just my few papers, and the current impact factor is not as good as NatureMaterials.

It's okay, with the professor here, sooner or later it will surpass Nature.

Wei Feng didn't have any doubts about this, Shen Min and Jiang Shuai also nodded in unison.

OK, then publish it in the origin journal.Chen Nuo smiled very relieved.

The second question, based on the results of your thesis, you can graduate. If you want to go to the future technology laboratory, you can go directly. If you want to go to other domestic laboratories or companies, I can also arrange for you.

With his contacts and status, plus Wei Feng's achievement, he is always eager to get it wherever he goes.

Professor, I don’t want to graduate yet. It’s been five years since I got my Ph.D., and I’ve only had half a year, which is still very early. I want to continue to study this, and my ultimate goal is more than 70%.

Wei Feng's eyes were full of determination.

They all remembered Chen Nuo's kindness to them. Although Chen Nuo was often not in the office, he was not picky in any way whether it was academic guidance or concern for life.

Moreover, staying here with Chen Nuo does not have any pressure for scientific research, and they can always listen to Chen Nuo's teachings. Every time Chen Nuo returns to the office to give them advice, they can suddenly see the light.

He has a very strong intuition that if he studies by himself, it may take him a lifetime to reach 70%, but under the guidance of Chen Nuo, it may only take 10 years or even less.

It's okay, if you want to stay, you can stay. You can mention it at any time when you want to graduate, and I will give you an answer at any time.

Chen Nuo is also very happy to have such a student.

Seeing that Chen Nuo agreed, Wei Feng also breathed a sigh of relief.

The third question, the patent in your thesis is very good, what do you want to do about the patent issue?

Professor, you call the shots!

Mess around, do your own research, what am I doing master.

Chen Nuo was a little speechless. Did he, a student, be stupid for doing research?

Wei Feng was silent, Shen Min and Jiang Shuai next to him looked at Wei Feng nervously, waiting for his decision.

The decision at this time is to think of heaven and hell.

Chapter 472 They don't need it, but we can't give it up

In the Huaqing Mathematics Office, the atmosphere is a bit delicate.

Chen Nuo was drinking tea leisurely, Wei Feng was expressionless, Jiang Shuai and Shen Min both looked at Wei Feng nervously.

No matter what decision Wei Feng made, Chen Nuo would never interfere.

These patents may be important to others, but they don't matter to me. Any patent I take out by myself is awesome.

He very much hopes that one day Wei Feng can increase the photoelectric conversion rate to 70%, or even higher.

If the photoelectric conversion rate is more than 70%, it is really possible that new energy vehicles do not need to be charged and discharged, and some thermal power plants can also be turned off.

Although Chen Nuo has BECCS and DACCS technologies, which can capture and store carbon dioxide in organisms and air, there are always dangers and unpredictability in storage, such as the release of gas by earthquakes and so on.

Solar energy is currently the purest form of energy.

Professor, this scientific research achievement, I just carried out and a small part of thinking, most of it was completed under the guidance of your thinking, and your credit accounted for more than 60%, so, this patent has 60% of yours, 5000 million RMB, I will transfer all this patent to you!

hiss!

Both Shen Min and Jiang Shuai gasped, only 5000 million echoed in their minds.

Hearing this decision, Chen Nuo couldn't help but look at Wei Feng more.

This decision exceeded his expectations.

Wei Feng, do you know what your decision means?

Last year, our photovoltaic power generation was 1700 billion kWh. According to a 5% increase, it was 85 billion kWh. Calculated at 0.5 yuan/kWh, the total benefit was 42.5 billion yuan.

This is only Xiaguo’s photovoltaics. Last year, the world’s photovoltaic power generation was 50000 trillion kwh, which is at least not much. According to this calculation, it can be 2500 billion kwh more, and the benefit is 1250 billion RMB.

Now the world's photovoltaic power generation only accounts for 2.7% of the total power generation. Xia Guo proposed that photovoltaic power generation account for 2030% of the total power generation by 40. Do you know what this concept is?Will you still make this decision?

Cough

Jiang Shuai and Shen Min, who had just been awakened by Chen Nuo's voice, were stunned again by Chen Nuo's series of numbers.

Professor, this is an ideal state. It only increases the photoelectric conversion by 5%. It is impossible for these photovoltaic companies to replace equipment in large quantities. If the photoelectric conversion rate is above 40%, I think those capitalists will definitely pay a lot of money to buy it. .

Wei Feng shook his head and continued: This technology will continue to be iteratively updated, and the capital is not stupid. As long as I apply for a patent for this technology, those big companies will definitely organize scientific researchers to conduct research on my basis. One person The power of a company cannot be faster than a company's research speed, and it will be easier for them to produce results if they accumulate.

Instead of making these companies cheaper, it is better to sell the patents to you directly. With you, the capital will not be too ugly;

If I personally hold the patent, they have a lot of ways to let me sell the patent, or directly block me. No unit will want me. Without funds and scientific research equipment, no matter how capable I am, I will not be able to make results.

I just want to be quiet and be a pure scholar, and I don’t want to be entangled by those right and wrong. Besides, this is my research for the benefit of mankind. 5000 million is enough to make me and my family worry-free in this life. So, I stand by my decision.

Unexpectedly, Wei Feng, who is usually dull, would utter such a big statement, and see the whole thing very clearly.

Is it more than 5000 million?

Not much really.

If the patent is spread, there is not even a fraction of the income.

Chen Nuo thought for a while, and said: How about this, Let Future Technology apply for the patent for you, the patent is yours, after the application is approved, sell it to Future Technology, and give you [-] million, how about it?

One billion?

Although Wei Feng was calm, he was shocked when he heard [-] million, and said quickly: Professor, this is too much.
