Chapter 394

The first is the mechanical properties of graphene

After several hours of research, Ni Guangnan was shocked to find that graphene is likely to be one of the strongest materials known, and its strength even far exceeds that of diamond. It is the hardest material on earth.

But the terrible thing is that graphene, as the material with the highest strength, also has good toughness and can be bent, which is something that diamond can never do.

There are many other tests on mechanical properties. The laboratory has no time to prepare, so they have not been done. However, the strength exceeding that of diamond alone is enough to make graphene stir the world and change the structure of the whole material industry.

Then the thermal properties of graphene

Graphene has very good thermal conductivity. The thermal conductivity of pure defect free single-layer graphene is as high as 5300wmk. It is the carbon material with the highest thermal conductivity so far, and it is also one of the best thermal conductivity materials in the world.

After all, the thermal conductivity of copper tubes now widely used is only 480, less than one tenth of that of graphene.

In addition, graphene has unimaginable excellent properties in terms of optical, solubility and chemical properties. Ni Guangnan said that the value of graphene in any characteristic is enough for him to stand at the peak of the same material.

When so many excellent properties are all concentrated on one substance, the prospect of graphene is almost unlimited.

"I'm afraid this is the material God gave us. He will become the fire of Prometheus and change the whole human technology!" finally, Ni Guangnan made such a judgment.

"Damn it, if I'm only 30 years old now, no, even if I'm only 35 years old, I won't study electronic technology and computer technology. I'm going to study graphene, which is enough for me to win 10 Nobel prizes!" Ni Guangnan gasped.

"Teacher, please calm down!" although Jia Yapeng has long known that graphene has these characteristics, he doesn't know much about the importance of graphene. He didn't feel that he underestimated graphene until he knew these things from Ni Guangnan.

"Boy, do you know what is the most important characteristic of graphene?" suddenly, Ni Guangnan asked again.

"I don't know..." Jia Yapeng shook his head.

"You guy, didn't you experiment with the conductivity of graphene and say that he has a chance to achieve superconductivity at room temperature?" Ni Guangnan scolded.

"Oh, I don't remember very clearly!" Jia Yapeng stuck out his tongue and said, "why, teacher, have you realized superconductivity?"

Hearing Jia Yapeng's question, Liu Nian pricked her ears in an instant.

"Fart, if I had achieved superconductivity, I would have won the Nobel Prize now!" Ni Guangnan rolled his eyes and said "Graphene does have unimaginable advantages in the conductive system, but it is still a little less than superconducting. In addition, if you really want to conduct superconducting experiments, you have to give me at least hundreds of millions of dollars of equipment. Now these equipment can't do material experiments!"

"Oh!" Jia Yapeng answered, feeling is to spend money on equipment.

"But our laboratory can test the carrier mobility. As you saw just now, the carrier mobility of graphene at room temperature is 15000. Do you know what this means?"

"I don't know..." Jia Yapeng shook his head.

"You pig, I told you about this a few days ago!" Ni Guangnan stamped his feet angrily and said, "I tell you, the reason why monocrystalline silicon is the best material for making chips is that it is the material with the highest carrier mobility among the materials that can be manufactured in large-scale industrial production, and its mobility is only 1500."

"If we can use graphene to make chips in the future, in terms of the material properties of graphene, it can increase the speed of single crystal silicon chips by one million times than that of single crystal silicon chips of the same grade. Any chip made of single crystal silicon is slag in front of graphene. This is the best chip material in the world. All previous chip related technologies and technologies, as well as special technology Li, after the birth of graphene, it will be all invalid and meaningless! "

"It's like the cold weapon civilization and war history that lasted for thousands of years after the emergence of semi-automatic rifles will be thrown into the history museum!" Ni Guangnan looked at the graphene crystal in the laboratory as if he were a beauty.

"There's such a thing!!" Jia Yapeng was stunned. He didn't pay attention to this in his previous life, so he didn't know that graphene could replace monocrystalline silicon and become a material for chip manufacturing.

"Teacher, how long will it take us to make a chip made of graphene?" Jia Yapeng asked curiously.

"This..." speaking of this, Ni Guangnan sighed and shook his head. "It's difficult, because graphene is too thin. In addition, in some other characteristics, it can't meet the needs of current chip technology. We must abandon all the original chip technology and develop a new set of chip technology according to the characteristics of graphene material."

"At the same time, large-scale production technology should be developed on the materials of graphene itself. This may be a new technology that can't be seen in 10, 20 years, or even when I die! So everything depends on the will of God. Maybe only when an Einstein comes down, I can see the birth of graphene chip in my lifetime!" Ni Guangnan sighed, Jia Yapeng silently glanced at Liu Nian behind him and found that Liu Nian was spread in front of the electron microscope and looked at the beautiful graphene crystal like dementia.

——————————

Under Jia Yapeng's mandatory order, two security guards took Ni Guangnan home to sleep, while Liu Nian stayed in the laboratory and continued to look at graphene. As for Jia Yapeng, he gave immediate orders to his personal bodyguard and Li Xu, who has been promoted to security minister, to see him.

"Boss!" Li Xu soon came to Jia Jiapeng.

"I ask you, how is the security system of the research center upgraded?" Jia Yapeng asked.

"Don't worry, boss. I'm sure there's no better place in China than the security of the Research Institute, except for some special places in imperial capital and magic capital, as well as your chairman's office!" Li Xu patted his chest.

He said this with confidence, because boss Jia invested US $10 million at one go, made a full set of security equipment, and carried out the most detailed and meticulous security work for the whole laboratory under the strict arrangement of Li Xu.

Although not to the extent that a fly can't fly in, at least a dog can't run in.

We should not believe too much that some pictures in the film and the defense systems of various research institutes are useless in front of those non thieves. As long as we crack the security system with a computer and avoid the infrared alarm system, we can steal things smoothly.

In fact, it's just a movie. At this time, unless the institute uses violence to break through, or buys some security guards to break through with the cooperation of insiders, there is no possibility to enter the Institute.

"Very good!" Jia Yapeng nodded and said, "this is just external defense. How are you doing with internal defense?" Jia Yapeng suddenly asked again.

"Ah?" Li Xu was stunned. He didn't know what Jia Yapeng meant.

"Listen, from today on, you must monitor all the researchers here. Not only their work in the Institute, but also all their behaviors when they leave the Institute and return home."

"Including who they met, what you said, and even every letter they sent and every network communication after connecting to the network in the future, you must monitor me. If they have any illegal actions, they must report to me at the first time. Especially when they go abroad, no one is allowed to leave the border without my permission and approval ！”

"At the same time, if some researchers have misdeeds, which will soon lead to the disclosure of major laboratory secrets, I allow you to do it directly, cheat, catch, or even kidnap directly, get it back to me!"

"Boss, is this necessary?" Li Xu looked at Jia Yapeng in horror. He suddenly found that he didn't know the boss.

"Of course, I tell you, there are things that can make China surpass the world for 10 years. If any words leak out, we will both become sinners of the nation and history!" Jia Yapeng said faintly. "No secrets shall be leaked out for at least ten years, at least ten years!"

Why ten years?

Because in ten years, graphene will be studied by foreigners.
