"Boss, I suggest you do a physical examination. After all, frequent nosebleeds for two consecutive months may be a sign of leukemia..."
Recalling that this happened to Chen Chen two months ago, 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 get sick from overwork. After all, you have made such a big movie If you fall, your country will be handed over to others..."
"Don't worry, didn't I just take a blood test some time ago?"
Chen Chen waved his hand, "I'm just angry, it's okay."
"All right… "
Seeing this, Qian Wenhuan could only nod his head and took out the iron box, "This is what you want."
"Is it functionalized graphene obtained through oxidation reaction?" Chen Chen asked.
"seems like it… "
Qian Wenhuan scratched his head, "I heard Professor Farah say that this stuff is harder than ordinary graphene sheets and has much higher toughness. However, in order to maintain this strength and toughness, Professor Farah used this kind of graphene to When it reached 100 layers, he said it was very dangerous and should be used with caution."
“100 layers of functionalized graphene?”
Chen Chen nodded, reached out to take the iron box and said, "Okay, it's almost enough."
After sending Qian Wenhuan away, Chen Chen locked the door of the laboratory again.
As the opening date of the Life Sciences City approached, Qian Wenhuan was extremely busy preparing for the opening ceremony of the Life Sciences City. But even so, Qian Wenhuan came in person every time no matter what Chen Chen ordered.
This can be regarded as a sincere intention.
Chen Chen shook his head. It seemed that he could compensate Qian Wenhuan for his promotion when he had time in the future.
But then I thought about it and realized that Qian Wenhuan was already the general manager of the African region and could not 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. Suddenly, pieces of almost transparent flakes appeared in the iron box.
Graphene is extremely light-transmissive. Although there are many layers stacked together, it is like glass and the light penetrates directly through the bottom of the box.
As for Qian Wenhuan saying this thing is dangerous, that's true.
What is graphene after all? That is basically a layer of carbon atoms. 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, Chen Chen held in his hands a graphene with a 100-layer structure, which was 34 nanometers thick and only one-thousandth of the thickness of a human hair.
Moreover, this graphene layer has been specially oxidized, which means that the edges of this material will be very sharp.
The jagged edges of graphene can easily pierce the cell membrane of the human body and penetrate into the human body, which is very lethal to humans and other animals.
Graphene was first isolated from graphite by two physicists at the University of Manchester in Europe: Andre Geim and Konstantin Novoselov.
The two also jointly won the 2010 Nobel Prize in Physics.
Since then, the world of physics has added materials like graphene, which is a two-dimensional crystal that is the strongest substance known to mankind and is harder than diamond.
It is both the thinnest material and the strongest material, with a breaking strength that is more than 200 times stronger than steel.
A laboratory in North America once conducted an experiment. Before graphene particles begin to fragment, they can withstand a pressure of about 2.9 micronewtons per 100 nanometers. This is equivalent to applying a pressure of 55N to make 1 Meter-long graphene breaks.
If this graphene material was made into the thickness of an ordinary food plastic packaging bag, a pressure of 20,000N would be needed to tear the packaging bag.
In other words, if a bag was made from graphene, it could hold an item weighing about two tons.
At this time, how powerful should the graphene sheet with a hundred-layer structure in Chen Chen's hands be
Thinking of this, Chen Chen's heart moved, and a thin, almost transparent sheet suddenly floated up from the box. Chen Chen looked closely, and saw that the sheet was indeed about the same size as a playing card.
But unlike playing cards, this sheet was almost completely transparent. If he didn't pay special attention, he could hardly detect the existence of this sheet.
Although this piece of graphene is very thin, it is very tough, not much different from playing cards. Chen Chen thought for a while, then simply picked up a book, opened it from the middle, and stood it on the table.
Then, Chen Chen controlled the graphene in front of him and used a poker technique to exert some force. Suddenly, the graphene flakes in front of him flew out silently.
Uh-huh!
There was an almost inaudible tearing sound. Chen Chen looked closely, only to find that several pages in the middle of the book were cut off at the waist!
Chen Chen carefully picked up the book, only to see a ten centimeter long, transparent gap in the middle of the book.
The cut surface of the gap is extremely smooth, as if books were born like this...
This is an attack at the atomic level.
Chen Chen looked back in the direction of the book and saw that behind the book was a pen holder, and the thin graphene layer was embedded in the pen holder, with only a small part of the outside exposed.
This power...
Chen Chen was secretly dumbfounded. If he used this method to attack someone, what would be the consequences? I'm afraid that even if that person dies, he doesn't know how he died.
And because it was too thin, I didn't even feel pain. At most, I felt a little itchy on my neck. Then I stretched out my hand to scratch it, and the adhesive force of flesh and blood completely failed, and the whole head fell off with a pop...
Chen Chen did not touch it with his hands, but continued to use the power of the "field" to take out the graphene sheet, only to see that one 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 objects with lower strength, it still cannot cut objects with higher hardness.
After all, it's still too thin.
If you want to achieve the level of cutting metal, unless it is hundreds of times thicker, it will be almost as thick as the blade.
However, although it cannot cut metal, this power is enough to satisfy Chen Chen.
Thinking of this, Chen Chen pointed the "field" at the iron box again and pulled out all the pieces of graphene inside. Only then did he discover that there were a total of one hundred graphene "playing cards" inside.
Nodding, Chen Chen took back the graphene sheets and put them into the iron box.
These graphene flakes are too destructive. If you hold them with your hands, you will easily hurt yourself. Moreover, because they are too thin, they will easily break with force. No one except Chen Chen can use such things as weapons.
Just when Chen Chen was finishing the experiment, Little
