I Have A Super USB Drive

"Boss, I suggest you take a physical examination. After all, frequent nosebleeds for two consecutive months may be a sign of leukemia..."

Reminiscing that this happened to Chen Chen two months ago, Qian Wenhuan looked worried, "You are only 22 years old this year, and you still have a lot of time to waste, so don't overwork yourself, after all, you have made such a big movie. Jiangshan, if you fall, Jiangshan will be handed over to others..."

"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."

"All right……"

Seeing this, Qian Wenhuan could only nod his head, and then took out the iron box, "This is what you want."

"Is it functionalized graphene obtained through an oxidation reaction?" Chen Chen asked.

"seems like it……"

Qian Wenhuan scratched his head, "I heard from Professor Farah that this thing is harder and much tougher than ordinary graphene flakes, but in order to maintain this strength and toughness, Professor Farah made this graphene Stacked to 100 layers, he said this thing is dangerous, use it carefully."

"100-layer functionalized graphene?"

Chen Chen nodded, reached out to take the iron box and said, "It's fine, 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 Science City approached, Qian Wenhuan was extremely busy preparing for the opening ceremony of the Life Science City, but even so, Qian Wenhuan would come in person every time no matter what Chen Chen ordered.

This is also a thought.

Chen Chen shook his head. It seems that he can compensate Qian Wenhuan for his promotion in the future when he has time.

But after thinking about it, Qian Wenhuan was already the general manager of the African region, and there was no room for promotion, so he gave up the idea of ​​compensating Qian Wenhuan.

Thinking of this, Chen Chen took out the iron box and gently opened it. Immediately, almost transparent sheets appeared in the iron box.

Graphene is extremely light-transmitting. Although there are many layers stacked together at this time, it is like glass, and the light penetrates directly through the bottom of the box.

As for Qian Wenhuan's claim that this thing is dangerous, that's true.

What is graphene after all? That is simply 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, in Chen Chen's hands was 100-layer graphene, which was 34 nanometers thick, only one-two thousandth the thickness of a hair.

Moreover, this graphene layer has been specially oxidized, which means that the edges of this material will be very sharp.

The serrations on the edge of graphene can easily pierce the cell membrane of the human body and penetrate into the human body, which is extremely lethal to humans and other animals.

Graphene was first separated 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 physics community has produced more materials such as graphene, which is a two-dimensional crystal and is the strongest substance known to mankind, harder than diamonds.

It is not only the thinnest material, but also the strongest material, with a breaking strength even more than 200 times stronger than steel.

A laboratory in North America once conducted an experiment. Before the graphene particles start to break apart, they can withstand a pressure of about 2.9 micronewtons per 100 nanometers, which is equivalent to applying a pressure of 55N to make 1 Meter-long graphene fractures.

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

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

And at this moment, how powerful should the hundred-layer graphene sheet in Chen Chen's hands be?

Thinking of this, Chen Chen's heart skipped a beat, and a thin, almost transparent sheet suddenly floated out of the box. Chen Chen looked intently, but saw that this sheet was indeed about the size of a playing card.

But unlike the playing cards, this sheet is almost completely transparent, and if he didn't pay special attention, he would hardly be able to detect the existence of this sheet.

It's just that although this piece of graphene is very thin, it is very tough, not much different from a playing card. After thinking about it, Chen Chen 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 exerted a little force with poker techniques, and immediately, the graphene sheet in front of him flew out soundlessly.

Swish!

There was an almost inaudible tearing sound, and Chen Chen looked intently, only to find that a few pages in the middle of the book were directly cut off in the middle!

Chen Chen picked up the book carefully, but saw a gap of ten centimeters long, transparent from front to back, in the middle of the book.

The cut surface of the gap is even more smooth, as if books are born to be like this...

This is an attack at the atomic level.

Chen Chen looked back in the direction of the book, but saw a pen holder behind the book, 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 silent. If he used this method to attack a person, what would be the result? I'm afraid that even if that person is dead, he doesn't know how he died.

And because it's too thin, I don't even feel pain. At most, I feel my neck is a little itchy, and then I stretch out my hand to scratch it, and the adhesion of the flesh and blood fails completely, and the whole head falls off with a snap...

Chen Chen didn't touch it with his hands, but continued to use the power of the "field" to take out the graphene sheet, only to see that a corner of the graphene sheet had been completely shattered.

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 is still too thin.

If you want to achieve the level of cutting metal, unless it is a few hundred times thicker, it is almost the same thickness as the blade.

But even though he couldn't cut metal, this power was 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 to find that there were a total of one hundred pieces of graphene "playing cards" inside.

Nodding his head, Chen Chen took back these graphene flakes and put them in an iron box.

These graphene flakes are too lethal. If you hold them with your hands, you will easily hurt yourself. Moreover, because they are too thin, they will easily shatter if 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, the Meyer shipyard in Germany has just sent a message that your customized cruise ship Black Light has been built and is ready for acceptance!"
