"Any other surprises?"

Su Yan smiled happily, jumped on Fang Chen, hugged Fang Chen and said excitedly.

"Seeing that you are happy, it seems that I usually treat you badly, Graphene, do you know?"

Fang Chen fondly shaved Su Yan's straight nose.

"Okay, of course, you are the best to me in this world!"

Since there was no one around, Su Yan was not afraid of people laughing. She pulled Fang Chen's neck and shook her gently, her soft and waxy voice even more vivid and vivid in her coquettish and cute expression.

Fang Chen glanced at Su Yan helplessly and said, "I said, do you know about graphene?"

"Of course I know about graphene. As a future Ph.D. in materials science, if you don't even know about graphene, it is simply a failure of Chinese education and even the global academic community. But why do you suddenly ask about graphene?"

Su Yan looked at Fang Chen and asked curiously.

Fang Chen was not surprised by Su Yan's answer. After all, it would be too sad if Su Yan really didn't even know about graphene.

Graphene, as the thinnest, strongest, and most electrically and thermally conductive new nanomaterial discovered so far, is also known as black gold and is the king of new materials.

Scientists even predict that graphene will completely change the 21st century. It is very likely to set off a disruptive new technology and new industrial revolution that will sweep the world.

The carrier mobility of graphene at room temperature exceeds 10 times that of silicon materials, and unlike many materials, the electron mobility of graphene is less affected by temperature changes.

This property of graphene can be used to create graphene batteries.

Graphene batteries are not only compact in appearance, but also charge 1,000 times faster than ordinary batteries. They can charge mobile phones and even cars within seconds, and can also be used to manufacture smaller devices.

Graphene also has the so-called quantum Hall effect. This important Nobel Prize-level effect used to be visible at extremely low temperatures, but graphene can bring it to room temperature.

Using this property, graphene can be used to make transistors, which are the main components of CPUs.

Due to the high stability of graphene's structure, this transistor can still operate stably at a scale close to that of a single atom.

In contrast, the silicon-based transistors currently taking the lead will lose stability at a scale of about 10nm.

In addition, flexible and bendable mobile phone screens can also be manufactured using graphene.

This knowledge is already familiar to people of later generations and is a treasure in every household. Many people have even used foldable mobile phones and batteries containing graphene.

But for people at this time, the knowledge and characteristics of graphene are still only spread among scientific researchers.

The reason is also very simple, because until now, scientific researchers have not been able to separate graphene from stone grinding, let alone mass manufacturing and industrialization.

The existing graphene is extracted by the miraculous work of nature.

The lack of raw materials has caused all research on graphene to be at a standstill. At most, it is just a side drum and some theoretical research.

As for why it is still impossible to peel graphene out of stone mills with today's advanced technological level, it is because graphene is really small and a bit abnormal.

Graphene only exists in a single atomic layer, and the thickness of a layer of graphene is only 0.335 nanometers.

It is equivalent to graphite that is only 1 mm thick and contains approximately 3 million layers of graphene. When a pencil lightly scratches the paper, the traces left behind may be thousands or even tens of thousands of layers of graphene.

Such a tiny crystal size cannot be separated out by the current level of technology.

"Don't worry about my reasons. If you ask about graphene, just tell me. Is graphene popular in your materials science?"

Fang Chen suddenly said with a smile.

"It's so hot. It's not an exaggeration to say it's so hot that it turns red and purple. There are already countless scientific research institutions in the world studying graphene, but the problem now is that we don't even have stable channels to obtain graphene, let alone

Industrialized it.”

"So now, all the world's first-class powers, even second-tier powers, and countless top materials scientists in various countries are actively developing graphene in order to break through the current dilemma."

"It can be said that the development of graphene is definitely a red sea among the red seas in academia, breaking new ground."

She has been with Fang Chen for nearly ten years. How could Su Yan not know that Fang Chen was hiding evil in his smile? But I have to say that Fang Chen successfully aroused her curiosity. After all, no matter how you look at it, Fang Chen is like

Graphene cannot match it.

"Then do you think, if someone can isolate graphene, can she win a Nobel Prize?"

Fang Chen continued to ask.

"The Nobel Prize? It is a big project that is crowded around the world. If someone can separate it first, the Nobel Prize will definitely not escape!"

Su Yan insisted and said decisively.

Are you kidding? How can we not win a Nobel Prize for a project where dozens of countries, hundreds of research units, and tens of thousands of individual researchers around the world are competing and working hard?

"But the problem is that no one has come up with a good solution yet. As far as I know, scientists have used methods such as oxidation, pure hydrazine solution, potassium manganate and sulfuric acid, and are also considering it.

By using other elements, such as ruthenium, to produce graphene."

"But unfortunately, the progress of scientific research is still stuck at being able to successfully decompose 10,000 layers of graphene. There is still a long way to go before we can achieve single-layer graphene."

Su Yan said regretfully.

Although graphene is good, its application is too difficult. Even just how to decompose it is difficult and suffocating.

And precisely because it is too difficult to decompose single-layer graphene, until now, there is no serious research on the decomposition of graphene in China, which can be said to be a backwater.

There is no way. Although China is not completely impoverished now, all scientific research tends to be projects that have been studied by Western developed countries in order to reduce the time and cost of their own exploration.

The other is to lean toward projects that can actually generate economic value.

In other words, those basic disciplines that cost a lot of money will not see any results for 30 to 50 years, and the investment is very small.

"That means that if you can decompose graphene, you will never win a Nobel Prize."

Seeing the expression on Fang Chen's face becoming more and more mean, Su Yan rolled her eyes at him and said angrily: "There is nothing wrong with what you say, but the problem is, where can I decompose graphene!

"

Who wouldn’t want to decompose graphene and win the Nobel Prize? But the problem is, I can’t do it!

"I will definitely be able to win the Nobel Prize. I will be relieved."

The smile on Fang Chen's face could already split dimensions and cut through time and space.

He had a clear idea of ​​whether he could win the Nobel Prize for successfully decomposing graphene, and what he just said was just a primer.

In a previous life, two British physicists successfully separated graphene from graphite using micromechanical exfoliation in 2004, and therefore jointly won the 2010 Nobel Prize in Physics.

It only took a total of six years from the emergence of the research results to the award of the Nobel Prize. This is a much shorter time than the 20 to 30 years waiting period for the award of the Nobel Prize.

"What do you mean? You should have mastered how to decompose graphene?"

After staying there for two full minutes, Su Yan finally came to her senses. She couldn't believe it and said overjoyed.

The meaning behind Fang Chen's words could not be more obvious, let alone someone like Su Yan who has been with Fang Chen for so long.

"That's probably what I mean." Fang Chen said with a smile.

"Then this is probably the biggest news in global materials science and even physics this year. I really want to congratulate this researcher who figured out how to separate graphene, and our Qingtian will also leave a mark in human history because of this. I

Now I want to see how graphene is decomposed, what an amazing and strange idea this is."

Although she had already guessed it, after it was confirmed by Fang Chen, Su Yan said ecstatically.

In particular, she feels extremely honored to be the first witness to artificial single-layer graphene.

"I can agree with the first few sentences, but not the last sentence, because graphene has not been decomposed yet, and you need to do it yourself."

Fang Chen pretended to be serious.

"It hasn't been decomposed yet and you need me to come? What does this mean?"

At this time, Su Yan was completely confused by Fang Chen and had no idea what Fang Chen meant.

If graphene has not yet been decomposed, how could Fang Chen say that graphene has been decomposed? Based on her understanding of Fang Chen, Fang Chen would not tell such a lie.

Moreover, why do you need her to come?

If she knew how to decompose graphene, she would have done it herself, and she would have had to wait until today.

"How should I put it? Except for the people in this room, no one knows how graphene decomposes, including Qingtian, and it is true that no artificial graphene has been born, so if you want to see graphene, you can only see it yourself.

Let’s take action.”

Fang Chen spread his hands and said calmly.

But Su Yan was obviously stunned by Fang Chen's words. She covered her head and stared at Fang Chen, thinking in confusion for a long time.

Then he said uncertainly: "You mean, you discovered the method of decomposing graphene yourself, and it has nothing to do with Qingtian."

"I didn't notice it. To be precise, you did."

Fang Chen waved his hand and quickly denied it.

"Let's stop making trouble. It's my birthday today. Let's go have a nice meal and I'll treat you. My supervisor just gave me a research subsidy of 200 yuan yesterday."

With that said, Su Yan took Fang Chen's arm and prepared to go out.

She accepted Fang Chen's kindness in trying to make her happy. As for the fact that Fang Chen discovered graphene by himself, if such a dog doesn't believe it, then forget it.

If graphene was discovered by Qingtian's scientific researchers, there is probably a third chance. After all, Qingtian's materials science laboratory is no less than the materials research of any top university.

But if it’s Fang Chen himself, haha!

It's not like she didn't know who Fang Chen was. He was pretty good at studying in high school, and who knows what happened, he even surpassed her in the college entrance examination and ranked first in the city.
