Chapter 292 The Hardest Substance in the World

In fact, Wang Fengfeng cannot be blamed.

He is engaged in computer information extraction, simply put, he is a hacker. Although I deal with information all day long, it is mostly due to task requirements.

Like the previous investigation of Lin Fan's information, it was John Woo's request.

After Lin Fan became one of her own, her information was encrypted.

In addition to basic personal information, higher-level information requires permission to view. For example, her special skill only has the word "transformation" in her personnel file.

Although everyone knows that she can transform into a star because of her special nature. But that’s because the previous video went viral and spread through word of mouth.

The information actually entered into the register is not visible to most people.

Except for a few relevant people at this meeting, no one else has access rights.

The detailed data information of the stars can be said to be top-level encrypted information.

Even John Woo only knows a rough idea. After all, those professional data are difficult for ordinary people to understand.

Jin Sichen has seen some. Although he has a high IQ, he can't understand the data even if the lines are separated by a mountain.

The information in Wenji's hands only included Lin Fan's personal information, and he also only had rough information about Xingchen.

He had little interest in things other than medicine. If Xingchen wasn't closely related to Lin Fan, he wouldn't even pay attention to it.

If the stars in the later period had nothing to do with Lin Fan's body, he would not apply for extra permission to view them.

Therefore, in the Special Office, apart from Zhu Cunjun, only Quan Yingdong and Ban Hai had all the information about Xingchen.

They are the ones who really understand. In addition to them, the research team prepared for the stars by the Special Branch will also become the group of people who know the stars best.

Wang Fengfeng did not have the habit of prying into people's privacy. Although he was concerned about Lin Fan's situation, he would not investigate in private. So it's normal that he doesn't know the true situation of Xingchen.

Quan Yingdong pulled the person aside to explain, and then Wang Fengfeng realized what stupid thing he had just said.

How hard are stars? Existing machines cannot measure it at all.

There was a bastard who could break her defense before. But since the upgrade, the gun is no longer useful and bends when touched.

So now we only know that the shell hardness of stars is the highest among known substances in the world.

How high exactly? have no idea.

"Harder than diamonds?" Wang Fengfeng has always believed that diamonds are the hardest material in the world.

Merchants use its strong and stable characteristics as gimmicks and make a lot of money.

Good-looking, really good-looking. But it’s also expensive!

"Diamond? That's not the hardest material to begin with." Quan Yingdong chuckled.

"Isn't it?" Wang Fengfeng has been a hacker for so many years. He thought that his knowledge reserve was sufficient, but he didn't expect that he would become a frog in the well today.

"The raw stone of a diamond is called a diamond, and it becomes a diamond after being polished with laser or diamond powder." Quan Yingdong saw everyone looking at him and smiled to popularize knowledge. "Maybe it's because we see diamond jewelry more often in life, so most people think diamonds are the hardest."

"In fact, before stars appeared, diamond was only the third hardest. It also had graphene and carbyne on it."

"Graphene?" Wang Fengfeng knew this. It is a new type of material that has emerged in recent years.

He also has several pieces of clothing that are said to be made with graphene fiber, which is antibacterial and warm. But didn’t he know that graphene turns out to be harder than diamond? Not a clothes maker?

"Yes, graphene. Sounds familiar, right? It is also a kind of carbon substance, which was first separated from graphite. Its chemical properties are exactly the same as diamond, but its physical structure is different. Its hardness is 20 times that of diamond. "

"Its uses are much wider than diamond. It is usually used in high-tech directions such as new energy batteries, biomedicine, and aerospace. In daily life, graphene is included in the display screens we use..."

"What's in the clothes? I bought several pairs of graphene underpants years ago..." Wang Fengfeng said, suddenly realizing that Lin Fan was sitting next to him, he stopped a little embarrassed.

"It is also added to clothes. But it is usually used as a heating material and added in the whole piece." Quan Yingdong replied, "Graphene has good thermal and electrical conductivity. But you are talking about underpants..."

He pondered for a moment and said, "Currently, the cost of preparing graphene is very high, and the purer it is, the better the effect. It is mostly used in industrial production of electronic technology. I don't know how much your pants cost, but If it does contain graphene, the price will definitely not be cheap."

"If you use a single layer of graphene to make a pair of pants." He made a triangle-sized gesture with his hand, "it would cost hundreds of millions of dollars. So if the clothing on the market does contain graphene, most of it will not have a high content. It should still have a multi-layer structure. , that is, the purity is not that high.”

"Ah..." Wang Fengfeng bought it from Xixi for 30 yuan and five pieces, and it also comes with free shipping.

Quan Yingdong continued, "I speculate that most of the current graphene clothing products have graphene powder added to the textile fibers. There is some, but the content is very small. Graphene does have antibacterial and antibacterial effects, but that It needs to be of high purity. I guess the amount of powder is useless."

Well, he was deceived... Wang Fengfeng was dejected for three seconds, but quickly recovered. At this price, what kind of graphene do you want?

"The hardest material is carbyne..."

"What's missing?" Wenji asked.

"Quickly or slowly, replace the word "vertical" next to the word "fire" and read quē. Carbon acetylene." Quan Yingdong knew that everyone would not come into contact with these things every day, so he explained it very carefully. "This is currently recognized as the hardest substance known in the world. It is more than forty times harder than diamond."

"It is also a carbon substance, a composite carbon chain composed of carbon atoms in the form of trivalent bonds. Its special structure creates such a high hardness. Currently, it can only be produced in relatively rare quantities in the laboratory. As far as I know As you know, the shell of 800’s bionic armor is made of this material.”

"It seems to be all carbon..." Lin Fan sighed.

Carbon does not seem to be hard, but it is a material that can be easily burned for heating. How come the top three hardest substances in the world are all made of carbon?

"That's because carbon can change into various forms and form many different chemical bonds. Likewise, it is also the basis of our life." Wen Ji explained to Xingchen's big head, "Don't we often call ourselves carbon-based life? That's right. Because the organic matter in our body is a combination of carbon atoms as the main chain and hydrogen, oxygen and nitrogen as additives."

"Oh..." I seem to understand, but I don't seem to understand.

Lin Fan nodded. That's right.

"So after Xingchen's hardness test broke the table, they gave Xingchen a carbyne plate to test." Quan Yingdong was also quite surprised when he saw this. "Three centimeters thick, one meter square carbyne plate, the stars can be ripped as effortlessly as paper."

Lin Fan remembered that there was such a test. She didn't know what she was doing, so she just followed the instructions.

The back panel was getting thicker and thicker, and the surface was getting bigger and bigger. She felt it was effortless, and she felt like poking tofu with her finger. After a few times, the test was not repeated.

It turns out that it is carbyne! It does feel effortless.

800 people know that they may faint from crying in the toilet.

Because carbyne is not very stable, it is not easy to refine. It took the whole institute so many years to create so many, and they were all used in forging the shell of the bionic armor.

Before the formal forging, I just gave it to Xingchen to test its hardness and strength. After a long time, I realized that it was of little significance, and no matter how much material I used, I couldn't measure the upper limit, so I stopped doing it.

Unexpectedly, Lin Fan still disliked it!

It’s simply unreasonable!

People with super powers are really...

It’s so annoying, eh eh eh eh…

I always thought that diamonds are the hardest, as if taught by a teacher. Fortunately, Baidu, otherwise it would be misleading.

I bought the graphene pants, but they turned out to be useless. Hahaha, I was fooled.
