Chapter 181 Show off...

Hearing such a term that is not very unfamiliar, this term has been very popular in the past two years,
He looked at Li Zhenhua and motioned for him to continue.

"Hey, that's right, graphene, what I have now, batteries, superchargers, motors,
This is the basis of everything, and everything is developed on the basis of graphene. "

While he was talking, Wang Yuesheng on the opposite side kept nodding his head.

"I still know a little about the basic material of graphene,

In the past two years, this concept has been very popular, please tell me about it in detail. "

For this question, he did not immediately answer.

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

As he spoke, he brought Wang Yuesheng and Liu Qian, who had come to his senses, to the shelf next to the wall of the laboratory,
The one on the shelf is black in appearance, and the roll is the graphene he prepared.

Pointing to the things on the shelf, he said again at this time.

"Chief, look at this roll of objects 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 them.
There are many directions that I know so far, so let me tell you in detail.
First of all, this material can be made into a chemical sensor, especially in medicine, it is an ideal form of electrochemical biosensor.

Secondly, I think this material is still a material that we can achieve cornering overtaking on semiconductors. It can completely replace silicon, the traditional material for manufacturing transistors.
Relatively speaking, the raw material of graphene is also an easy-to-obtain substance. It is just an upgraded material prepared from graphite.
In essence, graphene is actually a simple substance of carbon.

And transistors made of it perform better than silicon, but transistors made of silicon,
In my research, when you get to 10 nanometers, you lose stability, and graphene is different.

And one of the most important features of graphene is that electrons respond super fast to external fields.
So this allows transistors made of graphene to achieve extremely high operating frequencies, which can exceed transistors of the same size. "

After talking about the application, he paused, knowing that the other party should have questions to ask himself.

"You mean that the transistors made of graphene can allow us to complete the corner overtaking in semiconductors?"

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

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

"Well, although our current lithography machine is not that high in precision, 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.

In this way, we can also get the same result, the purpose is to improve the calculation speed, and the goal is the same! "

After his explanation, Wang Yuesheng also knew the important role of this material on semiconductors,

After Li Zhenhua finished speaking, he continued to speak.

"In fact, it is not only these application directions, but also has great development in the manufacture of flexible screens.

Although this flexible screen is not very useful for strengthening 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, which I have just mentioned, and it can also be used in biological batteries, which is of great help to the medical field.

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

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

It can also play a significant role in the aerospace field and in the manufacture of composite materials. "

He explained clearly to Wang Yuesheng what he knew about the application direction of graphene, and this was only what he knew.

Wang Yuesheng only had an idea of ​​this material before, but now for him, the impact this material can have is simply too great.

"Since the preparation of graphene was not easy before, there were not many actual products in this area.
And now I have been able to prepare a large number of high-quality graphene materials, whether it is single-layer or double-layer, few-layer or multi-layer, I can prepare in large quantities.

Excellent quality and large quantity! "

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

Many methods of preparing graphene have been studied, such as mechanical exfoliation method, redox method, silicon carbide epitaxy...

Many methods have their own advantages and disadvantages, but the method he chooses is the method of orientation epigenesis.

The mechanical exfoliation method still uses physical means, and it is a method to obtain graphene using extremely advanced differential centrifugation technology.
However, the production efficiency of this method is too low to form mass production at all, so this method was abandoned.

As for the redox method, although high-quality graphene can be obtained, the cost will remain high.
Various electrode solutions are used, and a large amount of nitric acid and sulfuric acid will be produced during the oxidation-reduction process, which poses a huge safety hazard and is likely to cause pollution.

After all kinds of methods are eliminated, the final choice is the method of orientation epigenesis,

This is a kind of graphene grown by using the atomic structure of the growth substrate. This method can produce graphene in large quantities.

However, the graphene prepared in this way is in the form of flakes, but the thickness is often different, and there will be adhesion between the substrate and the hard carbon layer.

So after he solved these bad things, the equipment he made was also produced by him,
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 kind of material can be produced in large quantities, just like Li Zhenhua's introduction just now, and the impact on some industries is really too great.

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

The research and development ability of the kid on the opposite side is really amazing, it seems that some difficult problems are not difficult for him at all.

Moreover, this kid also knows how to report to the higher authorities. If he pushes it to the market rashly, he doesn't know what big troubles will be caused!
Looking at him who had finished speaking and stood aside, Wang Yuesheng looked at him with an indescribable look.

"Very well, Comrade Li Zhenhua, well done, I understand what you said, and I will report it immediately when I go back.
As for what to do later, 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 go straight to the heavens, and report what he got out,

As for getting an answer or promise on the spot, it was impossible, so everything was within his expectations.

After talking about all the business matters, Wang Yuesheng also began to look at this automobile laboratory,

Everything was normal at first, but when he was looking at it, a corner of the laboratory caught his attention.
In fact, it is difficult not to attract attention. Before, because I had a serious matter to discuss, I didn't pay too much attention.

However, in the fairly tidy workshop, a mound of dirt suddenly piled up in the corner, and no one would draw their attention to it.

Curious, Wang Yuesheng walked towards the mound, and Li Zhenhua saw that the half-dug tunnel in the corner was found, and he was a little flustered for no reason.

When he got close to the mound, he realized 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 couldn't see the bottom due to light problems.

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

And Liu Qian, who followed, looked at the deep pit, turned his head to Li Zhenhua, and said something in a joking tone.

"What are you doing? Are you planning to dig into the center of the earth to see if there is a 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 suspiciously.

"Uh, you are..."

Li Zhenhua looked at the two people who were asking him questions at the same time, scratched their heads in embarrassment, and smiled embarrassedly.

"Hey hey, this one, um~,

Okay, let me say, don’t laugh at me when you say it,

In fact, this is not a research project, and I did not intend to dig into the center of the earth.

This is because last time after I experienced the gangster incident, for my own protection,
This is an underground tunnel I dug that leads to my house at the other end,
My thought was, since I'd be a target walking up there, why don't I go underground,
So after I had an idea, I started digging the tunnel. "

After listening to his words, the two of them fell into self-doubt at the same time. Is this world abnormal?Or the kid on the opposite side is not normal!

Who in a normal person would think so trickily about a problem and just dig a tunnel to go to work?Isn't this a typical person who is full and has nothing to do?
For a moment, neither of them knew what to say. In the silence, Wang Yuesheng looked at Dakeng to the right and Li Zhenhua didn't say a word.

At this moment, he saw that Wang Yuesheng was very curious about the big hole he dug, and thought that the other party wanted to go down and have a look.

"Chief, are you admiring my whimsy?

Are you curious about the tunnel dug under me, wait a minute, I'll take you down to have a look. "

Before Wang Yuesheng could react, the switch on the side of the runway wall was closed.

Then the equipment that delivered air to the tunnel started to work, and the deep pit that was still dark and couldn't see clearly lit up.

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

At this time, Li Zhenhua came over with a remote control in his hand, pressed it, and quickly lowered a round plate from the top of his head, which was suspended by four wire ropes.

When the plates were lowered into the round pit, except for the vertical ladder on the wall on one side of the round pit, the two-meter-diameter pit was covered perfectly.

He stepped up and did not forget to call the two old men to come up together.

The two old men were bold and skilled, and followed them to the simple lift.

Then the lift took the three of them down, and the height of 20 meters was converted into a floor of six or seven floors, and it fell to the bottom in just over 20 seconds.

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

With a hint of curiosity, he stretched his hand towards the wall, touching the hardened wall, but it still looked like mud on the outside.

"What's the matter with your wall? It looks like mud to me, but it feels almost like a stone to the touch!"

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

"Oh, the wall you're talking about, it's an application of graphene, right?

I invented a glue-like adhesive based on graphene, and through the automation equipment on the shield machine,
The excavated soil is squeezed and compressed by high-frequency vibration and then added with graphene adhesive,

In the end, you can get the appearance of this kind of wall, but don't underestimate this thing. In some properties, this thing is no worse than high-grade cement, and it also has waterproof and moisture-proof functions. "

Being pretended by him again, this is the most real thought in Wang Yuesheng's heart at present, and he doesn't want to be entangled with this thing that needs beating anymore.

He finished speaking to Wang Yuesheng, but he didn't wait for the other party's exclamation, which made him feel a sense of loss.

Some dejectedly led the two of them into the horizontal tunnel, and walked hundreds of kilometers forward in the tunnel before the three of them came to the end.

And this tunnel also gave the old man Wang Yuesheng a sense of powerlessness. The source of this feeling was Li Zhenhua, who brought him down carelessly in front of him.

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.

"Little Li, this tunnel has come to an end. I'll listen to you first and then I'll tell you something. You talk first!"

Wang Yuesheng's words made him a little confused, and he didn't know what it meant.

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

"Oh, yes, sir,

Look at the orange device at the end of the front, this is the electric power 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.

It can generate high-frequency vibrations during the excavation, and these vibrations will beat the soil dug out during the excavation, together with graphene adhesive, into a hardened wall surface,
Fully automatic and integrated operation, in addition to paying attention to whether the adhesive is enough, you must also pay attention to whether the cable is long enough.

It can be excavated about 10-50 meters forward every day, depending on the structure of the soil layer encountered. Now these excavations have totaled 500 meters, and the construction period is more than one month.
This is how I drill this tunnel, how about it?Advanced, as long as the shield machine passes by, this kind of finished tunnel will be formed,

And there will not be much useless soil. The soil on the ground is the unused soil in the 1500-meter tunnel excavation. "

He explained all the equipment he got out and the things needed for its operation to the two of them one by one, and the explanation was very detailed.

After Wang Yuesheng listened, he had to say that the kid in front of him was really a genius.
But sometimes, this kid will show some stupidity, and I feel that this may have something to do with the other party putting all their brainpower into research and development.

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

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

But I'm not talking about your bright brain, I'm talking about you breaking the law when you dig this tunnel.

Because the tunnel you are digging now is using underground resources, and underground resources belong to the country, so it can be regarded as stealing ore mining.
This is one of them, and the most important point is not this,

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

Without Wang Yuesheng, he really didn't want to think about it. He always thought that this was just a private act and would not violate any laws.

Then the other party asked him about the nature of the factory. You don't need to think about it. It already produces J-36. What kind of nature could it be?

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

Also, our factory is now a private military enterprise, capable of producing both military and civilian equipment. "

He also knew that something was wrong when he said this, and then he didn't say anything more.

"You also know that your factory is a factory that produces J-36, and the security work of the factory is still very strict.
But after your operations, the loopholes will come out, and the loopholes are being plugged in other places.

As for you, you manually dug a loophole yourself. If you hadn't developed the J-36, this tunnel alone could give you the crime of espionage. "

The serious expression on Wang Yuesheng's face, combined with his tone of voice, made him feel indescribable.

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

"Of course I know that you haven't thought about it that much. In the future, some things need to be thought about more, from many aspects,
What you can't think of is what you think, and you will think twice before you act.

Alright, let's not talk about this, you should block this tunnel when you have time. "

At this moment, after Wang Yuesheng finished speaking, he became a little downcast. This unformed plan just died.

But just filling it back 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'm just backfilling the 1500-meter horizontal tunnel. Can I keep the 20-meter-deep vertical shaft? I plan to dig an underground laboratory out of the space under my workshop."

He looked at Wang Yuesheng expectantly, and the other party did not disappoint him.

"I think it should be possible, but you have to go to the relevant department to file a record. I don't know anything about this. Anyway, you can do it yourself!"

When I got this answer, I suddenly felt that it wasn't too bad.
