Start with a blacksmith shop

I heard such a term that is not very unfamiliar. It has become very popular in the past two years.

He looked towards Li Zhenhua and motioned for him to continue.

"Hey, that's right, it's graphene. What I have now, batteries, superchargers, motors,

This is the basis of everything. Everything is developed on the basis of graphene. "

While he was talking, Wang Yuesheng opposite him kept nodding.

“I still know a little bit about graphene, the basic material.

This concept has become very popular in the past two years. Please tell me in detail. "

He did not immediately answer this question.

"Chief, come with me. I will take you to see the real thing. After seeing the real thing, I will explain it to you in detail."

As he said that, he took Wang Yuesheng and Liu Qian who had regained consciousness and walked to the shelf against the wall of the laboratory.

The black-looking roll on the shelf is the graphene he prepared.

Pointing to the items on the shelf, he spoke again.

"Chief, look at this rolled object, which is graphene. This is the multi-layer graphene I prepared.

The application prospects of graphene are very broad, and the direction I choose now is just one of the applications.

There are many directions that I know so far. I will tell you in detail,

First of all, this material can be made into chemical sensors, especially when used in medicine. It is an ideal electrochemical biosensor.

Secondly, I think this material is still a material that can achieve overtaking in corners in semiconductors. It can completely replace silicon, a traditional material for manufacturing transistors.

Relatively speaking, the raw material of graphene is also an easily available substance. It is just an upgraded material prepared from graphite.

In essence, graphene is actually carbon.

Moreover, the performance of transistors made of it is even better than that of silicon. However, transistors made of silicon,

In my research, when you reach 10 nanometers, you lose stability, and graphene is different.

And one of the most important characteristics of graphene is that electrons respond extremely quickly to external fields.

Therefore, this allows transistors made from graphene to reach extremely high operating frequencies and exceed transistors of the same size. "

After talking about these applications, he paused. He knew that the other party would have questions to ask him.

"Are you saying that transistors made of graphene can enable us to overtake us in semiconductors?"

Sure enough, just as he thought, Wang Yuesheng immediately grasped the key points of what he just said.

He nodded to Wang Yuesheng with a smug look on his face, and then explained to him in detail.

"Well, although our current photolithography machines are not that high in accuracy, we can start from another direction.

Since we can't make transistors smaller, we can definitely increase the operating frequency of a single transistor to the highest level.

In this way, we can also get the same result. The purpose is to improve the computing speed and achieve the same goal through different paths! "

After his explanation, Wang Yuesheng also learned about the important role of this material in semiconductors.

Li Zhenhua finished speaking and then continued speaking.

“In fact, it’s not just these application directions. There is also great development in manufacturing flexible screens.

Although this flexible screen is not of much use in increasing national strength, the application of this concept screen

Being able to squeeze the share of foreign screens can play a big role in the economy.

I have already made a new energy battery, as I have just said, and it can also be used in biological batteries, which will be of great help to the medical field.

Graphene can also effectively desalinate seawater. I think if this technology makes great progress, in terms of overall strategy, it can make our relationship with coastal desert countries closer.

It can also be used on photosensitive components, which is also an important part of the camera.

It can also play a major role in the aerospace field and manufacturing of materials. "

He gave Wang Yuesheng a clear explanation of what he knew about the application directions of graphene, and this was only what he knew.

Wang Yuesheng only had a concept of this material before, but now for him, the impact this material can have is simply too huge.

“In the past, because the preparation of graphene was not easy, there were not many actual products in this area.

And now I have been able to prepare high-quality graphene materials in large quantities. Whether it is a single layer or a double layer, a few layers or multiple layers, I can prepare it in large quantities.

Excellent quality and large quantity! "

After saying this, he couldn't help but fall into the memories of the graphene preparation equipment.

There are many methods for preparing graphene, including mechanical exfoliation, redox, silicon carbide epitaxy...

There are many methods with their own advantages and disadvantages, and the method he chose is the orientation epiphysis method.

The mechanical stripping method still uses physical means. It is a method that uses extremely advanced differential centrifugation technology to finally obtain graphene.

However, the production efficiency of this method was too low to achieve mass production, so this method was abandoned.

As for the redox method, although it can produce high-quality graphene, the cost will remain high.

Various electrode solutions are used, and during the redox process, a large amount of nitric acid and sulfuric acid will be produced, which poses huge safety risks and can easily cause pollution.

After various methods were eliminated, the final choice was the oriented epiphysis method.

This is a kind of graphene grown using the atomic structure of the growth matrix. This method can prepare graphene in large quantities.

However, the graphene prepared in this way is in the form of thin sheets, but often has different thicknesses, and it will bond with the matrix, thus hardening the properties of the carbon layer.

So after he solved these bad things, he also produced the equipment,

Various high temperature and high pressure equipment form a complete set of preparation equipment.

After hearing what he said, Wang Yuesheng became a little excited. This material can be prepared in large quantities, just like what Li Zhenhua just introduced, and it will have a huge impact on some industries.

After he finished speaking, several people present fell silent at the same time, especially Wang Yuesheng. For him, this trip was indeed not in vain.

The guy opposite has really great R\u0026D capabilities, and it seems like some difficult problems can't be difficult for him at all.

And this guy also knows how to report to his superiors. If he rushes to market it, who knows what big trouble it will cause!

Looking at him who had finished speaking and was standing aside, Wang Yuesheng looked at him with an indescribable expression.

"Very good, Comrade Li Zhenhua, good job. I understand everything you said. I will report it immediately after I return.

As for what to do next, let’s wait until the higher-ups make up their minds before making a decision! "

Li Zhenhua's purpose is also very simple. It is to find someone who can directly access Tianting and report what he has found.

It was impossible to get an answer or a promise on the spot, so everything was as he expected.

After chatting about all the serious matters, Wang Yuesheng also began to look at the automotive laboratory.

Everything was normal, but when he was looking around, a corner of the laboratory caught his attention.

In fact, it was difficult not to attract attention. Before, because I had serious things to talk about, I didn’t pay too much attention.

However, in the relatively tidy workshop, a mound of soil suddenly piled up in the corner, and no one would be able to attract their attention.

Out of curiosity, Wang Yuesheng walked towards the mound, and Li Zhenhua saw that the half-dug tunnel in the corner was discovered, and felt a little panicked for no reason.

When he got closer to the mound, he discovered that it was not just a mound, but a deep circular pit with a diameter of two meters in the middle of the mound.

The surrounding soil formed a crater-like appearance around the pit. Looking into the pit, he could not see the bottom due to light problems.

Looking at the pit and then at Li Zhenhua standing beside it, Wang Yuesheng was a little confused.

Liu Qian, who had followed, finished looking at the pit, turned to Li Zhenhua, and said something in a joking tone.

"What are you doing? Are you planning to dig to the center of the earth to see if there is an inner earth world in the center of the earth?

Have you read too many Verne novels? "

After Wang Yuesheng finished speaking to Liu Qian, he also asked him doubtfully.

"Uh, what are you..."

Li Zhenhua looked at the two people who were asking him questions at the same time, scratched his head in embarrassment, and smiled sheepishly.

"Hey hey hey, this, um~,

Okay, I’m telling you, don’t laugh at me when I say it.

In fact, this is not a research project, and I don’t want to dig to the center of the earth.

This is because after I experienced the gangster incident last time, I wanted to protect myself.

This is an underground tunnel I dug, and the other end leads directly to my house.

My thinking was, since I'd be a target if I walked up there, why not go underground,

So after I had the idea, I started digging the tunnel. "

After listening to his words, the two people who listened fell into self-doubt at the same time. Is this world abnormal? The boy opposite is not normal!

Who in the right mind would think so cunningly and dig a tunnel directly to work? Isn't this typical of someone who is full of food and has nothing to do?

For a moment, neither of them knew what to say. In silence, Wang Yuesheng looked from Dakeng to Li Zhenhua without saying a word.

At this moment, he saw Wang Yuesheng being very curious about the big hole he had dug, and for a time he thought that the other person wanted to go down and have a look.

"Chief, are you admiring my fantastic ideas?

Are you curious about the tunnel I dug below? Just wait, I'll take you down to have a look. "

As he said this, before Wang Yuesheng could react, the switch beside the runway wall was closed.

Then the equipment that pumped air into the tunnel started to operate, and the deep pit that had been dark just now and couldn't see anything started to light up.

It was also at this time that Wang Yuesheng discovered that the walls of the deep pit were not original soil, but a treated wall.

At this time, Li Zhenhua came over with a remote control in his hand, pressed it, and soon a round plate lowered from above his head, suspended by four wire ropes.

When the plate is lowered into the circular pit, except for the vertical ladder on the wall on one side of the circular pit, the two-meter-diameter pit is perfectly covered.

He walked up, not forgetting to ask the two old men to come up with him.

The two old men were both skilled and brave, so they stepped onto the simple lift.

Then the elevator took the three people down. The height of 20 meters was converted into a floor of six or seven floors. It took just over 20 seconds to reach the bottom.

A horizontal tunnel was revealed in front of them. Wang Yuesheng did not walk into the tunnel, but was very interested in the walls of the tunnel.

With a trace of curiosity, he stretched his hand towards the wall and touched the hardened wall, but it still looked like dirt on the outside.

"What's wrong with your wall? It looks like dirt to me, but it feels almost like stone!"

Wang Yuesheng asked him curiously, but Li Zhenhua didn't take it seriously and returned casually.

"Oh, the wall you are talking about is an application of graphene, right?

I invented a gel-like adhesive based on graphene, and through the automated equipment on the shield machine,

The excavated soil is subjected to high-frequency vibration, extrusion and compression, and graphene binder is added.

In the end, you can get what this kind of wall looks like. Don't underestimate this thing. In some properties, this thing is no worse than high-grade cement, and it is also waterproof and moisture-proof. "

He had tricked him again. This was the most real thought in Wang Yuesheng's heart at present. He didn't want to get entangled with this thing that deserved a beating anymore.

He finished speaking to Wang Yuesheng, but there was no exclamation from the other party, which made him feel a sense of loss.

Somewhat dejectedly, he led the two of them into the horizontal tunnel. After walking forward for hundreds or thousands of meters in the tunnel, the three of them finally reached the end.

This tunnel also gave the old man Wang Yuesheng a sense of powerlessness. The source of this feeling was the Li Zhenhua who led him down carelessly.

Looking at the cylindrical machine with a diameter of two meters and an unknown length at the end of the tunnel, it should be the shield machine that Li Zhenhua just mentioned.

"Xiao Li, this tunnel has come to an end. I'll listen to your explanation first, and then I'll tell you something. You go first!"

Wang Yuesheng's words really confused him and he didn't know what they meant.

But the other party asked him to introduce it, and he still explained it to him.

"Oh, okay, Chief,

Look at the orange-red equipment at the end of the front. This is the electric shield machine I made.

A total of four 480kw motors are used as power, with a diameter of 2 meters, a length of 3.5 meters, and a total weight of 4 tons.

High-frequency vibrations can be generated during excavation. These vibrations will harden the soil excavated during the excavation and the graphene adhesive into a hardened wall.

Completely automatic and integrated operation. During work, in addition to paying attention to whether the adhesive is sufficient, you must also pay attention to whether the cable is long enough.

We can dig forward about 10-50 meters every day, depending on the soil structure encountered. Now we have dug a total of 1,500 meters, and the construction period is more than a month.

This is how I dig the tunnel, how about it? Advanced, as long as this shield machine passes through, this kind of finished tunnel will be formed.

And not much useless soil will be produced. The soil on the ground is the soil that has not been used during the excavation of the 1,500-meter tunnel. "

The equipment he got out and the things used in the operation of the equipment were all explained to the two of them one by one, and they were explained in great detail.

After listening to this, Wang Yuesheng had to say that the boy in front of him was really a genius.

But sometimes, this kid will show off some foolishness. I feel that this may be related to the fact that the other party devotes all his brainpower to research and development.

After Li Zhenhua finished speaking, the smile on Wang Yuesheng's face disappeared and became serious.

"Comrade Li Zhenhua, first of all, I admit that you are very smart, extremely smart.

But what I want to say is not your clever brain. What I want to say this time is that when you dig this tunnel, you have already violated the law.

Because the tunnel you are digging now is making use of underground resources, and underground resources belong to the state, and it can also be regarded as illegal mining.

This is one of them, but the most important point is not this.

Do you know the nature of the factory we are in now? "

Without Wang Yuesheng, he really would not have thought about this aspect. He always thought that this was just a private behavior and would not violate any laws.

Then the other party asked him about the nature of the factory. He knew this without even thinking about it. It already produced J-36s, so what kind of nature could it be.

"Chief, I really don't know if it is illegal for me to dig this tunnel. Is this serious?

In addition, our factory is now a private military enterprise and can produce military and civilian equipment. "

After saying this, he also knew that something was wrong, and then he said nothing more.

"You also know that your factory is a factory that produces J-36s. The factory's security work is very strict.

But after your operation, the loophole has appeared, and loopholes are being plugged in other places.

As for you, you dug a loophole manually. If you hadn't developed the J-36, this tunnel alone would have charged you with espionage. "

The serious expression on Wang Yuesheng's face, combined with the tone of his words, gave him an indescribable feeling.

"Chief, I really don't know. I didn't think about it that much before!"

"Of course I know you haven't thought that much. You need to think more about some things in the future, and think about them from many aspects.

Whatever you can't think of is what you think, and you should think twice before you act.

Okay, let’s not talk about this anymore. You’d better block this tunnel when you have time. "

At this moment, after Wang Yuesheng finished speaking, he became a little downcast, as his plan, which had not yet been formed, was aborted.

But just backfilling it like this, Li Zhenhua was still a little unwilling, his mind started to work quickly, and after thinking of something, he looked at Wang Yuesheng uncertainly.

"Chief, tell me, I only backfilled the 1,500-meter horizontal tunnel. Can I keep the 20-meter-deep shaft? I plan to dig an underground laboratory in the space under my workshop."

He looked at Wang Yuesheng with hope, but the other party did not disappoint him.

"I think it's possible, but you have to go to the relevant department to make a record. I don't know anything about this. Anyway, you can just handle it yourself!"

After receiving such a reply, I suddenly felt that it was not so bad.
