Boss, I recommend you to do a medical check-up, after all, frequent nosebleeds for two months in a row can be a sign of leukemia......"

Thinking of Chen Chen's situation in the past two months, Qian Wenhuan looked worried, "You are only twenty-two years old this year, and you still have a lot of time to squander, don't become ill, after all, you have laid down such a large area of the country, if you fall, the country will be handed ......over."

"Don't worry, didn't I just have a blood test some time ago?"

Chen Chen waved his hand, "I'm just angry, it's okay." ”

"Okay......"

Seeing this, Qian Wenhuan had no choice but to nod, and took out the iron box instead, "This is what you want." ”

"Is it functional graphene obtained by oxidation?" Chen Chen asked.

"It seems to be ......"

Qian Wenhuan scratched his head, "I heard Professor Farah say that this thing is harder and tougher than ordinary graphene flakes, but in order to maintain this strength and toughness, Professor Farah stacked this graphene to 100 layers, he said that this thing is very dangerous, and you should use it carefully." ”

"100 layers of functional graphene?"

Chen Chen nodded, stretched out his hand to take the iron box and said, "It's okay, it's almost enough." ”

After sending Qian Wenhuan away, Chen Chen relocked the door of the laboratory.

As the opening date of the Life Science City approached, Qian Wenhuan was very busy preparing for the opening ceremony of the Life Science City, but even so, every time Chen Chen had any instructions, Qian Wenhuan came in person.

That's a thought.

Chen Chen shook his head, it seems that he can compensate for Qian Wenhuan's promotion if he is free in the future.

But after thinking about it, Qian Wenhuan was already the general manager of the African region, and he couldn't be promoted, so he gave up the idea of compensating Qian Wenhuan.

Thinking of this, Chen Chen took out the iron box and opened it gently, and suddenly, pieces of almost transparent flakes appeared in the iron box.

Graphene is extremely light transmitted, and although there are many layers stacked on top of each other, it is like glass, and the light penetrates through the bottom of the box.

As for Qian Wenhuan saying that this thing is dangerous, this is really true.

What is graphene after all? It is simply a layer of carbon atoms, and a layer of carbon atoms is called a layer of graphene, and the thickness of a single carbon atom is only 0.34 nanometers.

At this time, in Chen Chen's hand, there was a 100-layer structure of graphene, which was 34 nanometers thick and only one-second of the thickness of a hair.

Moreover, this graphene layer is specially oxidized, which means that the edges of this substance will be very sharp.

The serrations on the edge of graphene can easily pierce the cell membrane of the human body and drill into the human body, which has a very great lethality to humans and other animals.

Graphene, on the other hand, was first isolated from graphite by two physicists at the University of Manchester in Europe: Andrei Geim and Konstantin Novoselov.

The two were awarded the 2010 Nobel Prize in Physics.

Since then, the physics community has developed graphene, a two-dimensional crystal, the strongest substance known to man, and harder than diamond.

It is both the thinnest and strongest material, with a breaking strength more than 200 times stronger than steel.

A laboratory in North America once conducted an experiment that graphene particles could withstand a pressure of about 2.9 micronewtons per 100 nanometers before they began to break up, which is equivalent to applying 55 N of pressure to break 1 meter of graphene.

If this graphene material is made into the thickness of ordinary food plastic packaging bags, then a pressure of 20,000N is required to tear off this packaging bag.

In other words, if a bag is made of graphene, it can withstand an item weighing about two tons.

And at this time, how powerful should this hundred-layer graphene sheet in Chen Chen's hand be?

Thinking of this, Chen Chen's heart moved, and suddenly a thin sheet that was almost transparent floated up from the box, Chen Chen looked at it, but saw that this thin slice was indeed about the same size as a playing card.

But unlike playing cards, the sheet was almost completely transparent, and he could barely detect it unless he paid special attention.

It's just that although this graphene is very thin, it is very tough, and it is not much different from playing cards, Chen Chen thought about it, and simply picked up a book and opened it from the middle, and stood it on the table.

Then, Chen Chen controlled the graphene in front of him, and used the poker technique to exert a little force, and suddenly, the graphene flakes in front of him flew out silently.

Swish!

An almost inaudible tearing sound came, Chen Chen looked fixedly, but found that the middle pages of the book were directly cut off!

Chen Chen carefully picked up the book, but saw that in the center of the book, there was a ten-centimeter-long gap that was transparent from front to back.

The cut of the notch is even smoother, as if books are born like this......

This is an attack at the atomic level.

Chen Chen looked back in the direction of the book, but saw that behind the book was a pen holder, and the thin graphene layer was embedded in the pen holder, only a small part of the outside was exposed.

This power ......

Chen Chen was secretly dumbfounded, if he used this method to attack a person, what kind of result would it cause? I'm afraid that even if that person died, he didn't know how he died.

And because it's too thin, I don't even feel pain, at most, I feel a little itchy in my neck, and then I reach out and scratch it, and the adhesive force of the flesh and blood completely fails, and the whole head falls off with a snap......

Chen Chen did not touch it with his hands, but continued to use the power of the "field" to take out the graphene sheet, but saw that the corner of the graphene sheet had completely broken apart.

Seeing this scene, Chen Chen also confirmed one thing.

In other words, although a 100-layer graphene sheet can cut through objects with low strength, it still cannot cut objects with high hardness.

It's still too thin after all.

If you want to cut the metal, unless it is hundreds of times thicker, it is about the same thickness as the blade.

However, although it was impossible to cut the metal, this power was enough to satisfy Chen Chen.

Thinking of this, Chen Chen once again aimed the "field" at the iron box and brought out all the pieces of graphene inside, only to find that there were a total of 100 graphene "playing cards" inside.

Nodding, Chen Chen took back these graphene flakes and put them into the iron box.

These graphene flakes are too lethal, if you grab them with your hands, it is easy to hurt yourself, and because they are too thin, they are easy to shatter when you use force, except for Chen Chen, no one can use this kind of thing as a weapon.

Just when Chen Chen had just finished the experiment, Xiao X reminded again, "Your Excellency Godfather, the German Meyer Shipyard has just sent a message that your customized Black Light cruise ship has been built and is ready for acceptance!" ”
