Hearing such a term that is not very unfamiliar, this word has been very hot in the past two years,

looked at Li Zhenhua and motioned for him to continue.

"Hey, that's right, it's graphene, I'm here now, batteries, superchargers, motors,

It's the foundation of everything, and everything is based on graphene. ”

As he spoke, Wang Yuesheng on the other side kept nodding.

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

This concept has been very hyped in the last two years, you can tell me more about it. ”

He did not immediately answer this question.

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

Saying that, with Wang Yuesheng and Liu Qian, who came back to his senses, he walked to the top of the shelf against the wall of the laboratory.

The shelf on top of the shelf is black in appearance, and the roll is the graphene he prepared.

Pointing to the things on the shelf, he said again.

"Chief, you see that this roll of objects is graphene, and this is the multi-layered graphene that I prepared.

The application prospect of graphene is very extensive, and the direction I choose now is just one of the applications.

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

First of all, this material can be made into chemical sensors, especially in medicine, and is an ideal form of electrochemical biosensors.

Secondly, I think this material is also a material that we can overtake in corners on semiconductors, and it can completely replace silicon, the traditional material for manufacturing transistors.

Graphene, the raw material, is also an easily available substance, and it is just an upgraded material prepared from graphite.

Essentially, graphene is carbon element.

And the transistors made from it perform better than silicon, but transistors made of silicon,

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

And one of the most important characteristics of graphene is that the electrons react super fast to the external field.

So this allows the transistors made of graphene to reach very high operating frequencies and exceed transistors of the same size. ”

After saying this, he paused, he knew that the other party should have questions to ask him.

"Are you saying that 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 point of what he had just said.

nodded at Wang Yuesheng with a smug face, and then explained in detail to the other party.

"Well, although our current lithography machine is not so high in accuracy, we can start from another direction.

Since we can't make the transistor smaller, we can increase the operating frequency of a single transistor to the maximum.

In this way, we can also get the same result, which is to increase the speed of computing, and the opposite goal is the same! ”

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

And Li Zhenhua finished speaking, and then continued to speak.

"In fact, it's not just these application directions, there is also a great development in the manufacture of flexible screens.

Although this flexible screen is not of much use for the enhancement of national strength, the application of this conceptual screen,

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

New energy batteries, I have made it, I have just said this, and it can also be used in biological batteries, which is of great help to the medical field.

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

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

It can also play an important role in the aerospace field and in the manufacture of materials. ”

He explained 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 that 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 I am now able to prepare high-quality graphene materials in large quantities, whether it is single or double layer, few layers or multiple layers, I can prepare large quantities.

Excellent quality, large quantity and full! ”

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

There are many kinds of preparation methods for graphene, such as mechanical exfoliation, redox method, silicon carbide epitaxy method...

Many methods have their own advantages and disadvantages, and the method he chose was the method of orientation epiphysis.

The mechanical exfoliation method still uses physical means, and it is a method that uses extremely advanced differential centrifugation technology to finally obtain graphene.

However, the production efficiency of this method is too low to form mass production, so this method is abandoned.

The redox method, although this can obtain high-quality graphene, but the cost will remain high.

In the redox process, a large amount of nitric acid and sulfuric acid will be produced, which has huge safety hazards and is easy to cause pollution.

Various methods are excluded, and the final choice is the orientation epiphytic method.

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

However, the graphene prepared in this way is in the form of a thin sheet, but it often has different thicknesses, and it will cause adhesion to the matrix, resulting in hard carbon layer characteristics.

So after he solved these bad things, he also made the equipment out of him.

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

After getting what he said, Wang Yuesheng became a little excited, this material can be prepared in large quantities, just like Li Zhenhua's introduction just now, and the impact on some industries is really huge.

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

The kid on the other side has really great research and development ability, as if some problems can't stop him at all.

And this kid also knows how to report upwards, if he rushes to the market, he doesn't know what kind of mess he will make!

Looking at him who was standing aside after speaking, Wang Yuesheng looked at him with an indescribable look.

"Very good, Comrade Li Zhenhua, good job, I understand what you said, I will report it immediately when I go back,

As for what to do later, let's wait for the above to make up our minds! ”

Li Zhenhua's purpose is also very simple, it is completely to find someone who can go directly to the heavens and report what he has come up with.

As for getting an answer or a promise on the spot, it was impossible, so everything was expected by him.

After chatting about all the business, Wang Yuesheng also began to look at the automobile laboratory.

Everything was normal, but just as he was looking, a corner of the laboratory caught his attention,

In fact, it's hard not to attract attention, because I had something to talk about, so I didn't pay too much attention to it.

But in the fairly neat workshop, a mound suddenly formed in the corner, and no one would attract their attention.

With curiosity, Wang Yuesheng walked towards the mound, and Li Zhenhua saw that the half-dug tunnel in the corner had been discovered, and he was a little flustered for no reason.

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

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

looked at the deep pit, and then looked at Li Zhenhua standing on the side, Wang Yuesheng was a little confused.

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

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

Isn't Verne's too much! ”

Wang Yuesheng finished speaking in Liu Qian, and then asked him suspiciously.

"Uh, you're here..."

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

"Hey, hey, hey, this, uh~,

Okay, I said, don't laugh at me when you say it,

Actually, this is not a research project, and I don't want to dig into the center of the earth.

This is because the last time I experienced the bandit incident, for a protection of myself,

This is an underground tunnel that I dug to lead to my house at the other end.

My thought was, since I'm going to be the target when I walk on it, why don't I go underground,

So after I had the 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? It's still not normal for this kid on the other side!

Who would be a normal person to think about the problem so trickily and dig a tunnel to work directly? Isn't this typical of people who have nothing to do to do it?

For a while, neither of them knew what to say, and in silence, Wang Yuesheng looked at Dakeng and Li Zhenhua didn't say a word.

At this moment, he looked at Wang Yuesheng and was very curious about the big pit he had dug, and once thought that the other party wanted to go down and take a look.

"Chief, are you admiring my whimsy?

Are you curious about the tunnel dug under me, you wait, I'll take you down to see. ”

Without waiting for Wang Yuesheng to react, the electric switch on the side of the runway wall closed.

Then the equipment that sent air to the tunnel was activated, and the inside of the deep pit, which had just been pitch black, and it was impossible to see anything clearly, lit up.

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

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

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

walked up, and did not forget to beckon the two old men to come up together.

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

Then the elevator took the three of them downward, and the height of twenty meters was converted into six or seven floors, and it only took more than twenty seconds to drop to the bottom.

In front of their eyes, a horizontal tunnel was revealed, and Wang Yuesheng did not enter the tunnel, but was very interested in the walls of the tunnel.

With a hint of curiosity, he reached over to the wall, touching the hardened wall, but it still looked like dirt.

"What's the matter with your wall? I look like it's still dirt, but it feels like a stone! ”

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

"Oh, the wall you're talking about, this is a kind of use of graphene, right?

I invented a gelatinous adhesive based on graphene, and after the automation equipment on the shield machine,

The excavated soil is extruded and compressed by high-frequency vibration and graphene binder.

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

was pretended by him again, this is the truest thought in Wang Yuesheng's heart at present, and he doesn't want to be entangled with this unbeaten thing 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 in his heart.

Some of them walked into the horizontal tunnel with their heads down, and walked hundreds of kilometers forward in the tunnel before the three of them came to the end.

And this tunnel also gave Wang Yuesheng, the old man, a sense of powerlessness, and the source of this feeling was the one in front of him, Li Zhenhua, who had no heart or lungs to bring him down.

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

"Xiao Li, this tunnel has also come to an end, I'll listen to you explain first, and then I'll tell you something. You speak first! ”

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

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

"Oh, yes, chief,

Look at the orange device at the end of the front, this is the electric shield machine I made.

It is powered by four 480kw motors 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 tunneling, which will harden the wall with the graphene binder of the soil excavated during the tunneling.

Fully automatic integrated operation, in the work out of the work to pay attention to whether the adhesive is enough, but also to pay attention to whether the cable is long enough,

It can excavate about 10-50 meters per day, depending on the soil structure encountered, and now these tunnels have been excavated for a total of 1,500 meters, and the construction period is more than one month.

This is how I excavate this tunnel, how? Advanced, as long as this shield machine passes, this finished tunnel will be formed.

And there won't be much useless dirt on the ground, which is the soil that hasn't been used up in the 1,500-meter tunneling. ”

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

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

But sometimes, this kid will be a little stupid, and I feel that this may have something to do with the other party's putting all of their brainpower into research and development.

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

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

But I'm not talking about your clever brain, I'm going to say that you broke the law when you dug this tunnel.

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

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

You know what the nature of the factory is now! ”

Without Wang Yuesheng's words, he really didn't want to think about this aspect, he always thought that this was just a private act, and it wouldn't break any laws.

Then the other party asked him about the nature of this factory, which you don't need to think about to know, it is all producing J-36, what kind of nature can it be.

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

In addition, our factory is now a private military enterprise, which is capable of producing military and civilian equipment. ”

He knew something was wrong with that, and then he didn't say anything more.

"You still know, your factory is a factory that produces J-36, and the security work of the factory was originally very strict.

But after your operation, the loopholes will not come out, and the loopholes are being plugged elsewhere.

As for you, you have manually dug a loophole, if it weren't for the J-36 developed by you, this tunnel alone can give you a crime of espionage. ”

The serious expression on Wang Yuesheng's face, and the tone of his speech made him feel indescribable.

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

"Of course I know that you don't think about it so much, and there are some things that you have to think about more in the future, and think about it from many aspects,

You can't think of what it is, and think twice about it.

Okay, let's not talk about this, you still have time to plug this tunnel. ”

At this moment, after he finished Wang Yuesheng's words, he became a little depressed, and the plan that had not yet taken shape died like this.

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

"Chief, you said, I just backfill the 1,500-meter horizontal tunnel, the twenty-meter-deep shaft, can I stay, I plan to dig a laboratory under the space under my workshop."

looked at Wang Yuesheng with a look of hope, and the other party did not disappoint him.

"I think it should be possible, but you have to go to the relevant departments to make a record, I don't know anything about this, anyway, you can handle it yourself!"

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