Chapter 321 Points, whoever opposes me, who is in a hurry!
"what?"

"Did you really find something?"

"Student Jiangnan, this... what is this?"

As Jiang Nan picked up the graphene from the ground, the teachers at the door immediately swarmed up.

Even Huang Ting and Fang Guoping couldn't stop them.

But if you find something, you don't need to stop it.

In this regard.

Jiang Nan didn't mind either.

Instead, he just tossed what was in his hand, "This is the result of my experiment, a perfect graphene crystal!"

Whoa whoa whoa!
When the words came out, everyone was shocked.

There was one person present, all of them stared wide-eyed and opened their mouths wide, with expressions of disbelief.

Not because of the word graphene.

after all!

Graphene is precious though.

It is a new type of nanomaterial with the thinnest, hardest, and strongest electrical and thermal conductivity found so far.

In terms of value, it is far above carbon fiber, light alloy carbon nanotubes, superconducting materials, semiconductor materials, etc.

It is said to be ten times more expensive than gold.

Known as "black gold" and "king of new materials".

But graphene was discovered by two potatoes and two scientists as early as [-], and won the Nobel Prize in Physics in [-], and then the production methods emerged in endlessly.

The common ones are mechanical stripping method, redox method, SiC epitaxial growth method, and chemical vapor deposition method.

so……

Graphene is not hard to see these days.

But the reason why they are still so stunned is the word "perfect" in front of graphene.

Perfect graphene.

It has never appeared so far!
Not to mention perfect.

Even ultra-high-quality graphene is difficult to produce, which is why graphene has been difficult to popularize although it is good and has many functions.

Although graphene has been discovered for more than ten years, and there are so many production methods, the real progress is very slow, because these production methods have great defects.

Mechanical peeling method.

The operation is very simple, but the controllability is poor, and the size of the graphene produced is small and there is a large uncertainty. At the same time, the efficiency is low and the cost is high, so it is not suitable for large-scale production.

redox method.

The same operation is simple, and the cost is also low, and the output is high, but the product quality is low, and a large amount of concentrated acid will be used, which will pollute the environment very much and cannot be produced on a large scale.

SiC epitaxial growth method.

This can produce high-quality graphene, but it is not only costly, but also requires the creation of an ultra-high vacuum high-temperature environment, which places extremely high requirements on the quality of mechanical equipment.

and so……

This method is also not universal.

As for the last one, chemical vapor deposition method.

Although it is currently the most effective way to make graphene, and the quality is good, it is also expensive.

Moreover, what this method produces is a graphene film, which is too thin to be used in a large area.

In a word.

At present, graphene has invincible efficacy and can be applied to all fields such as composite materials, textile fields, electronic information, energy conservation and environmental protection, biomedicine, chemical industry, and aerospace.

However, due to various factors such as the high cost of its manufacturing process and the low quality of the product, its development is not fast.

same.

It is not fast in theoretical research.

Because so far, no perfect graphene has been produced, so various theories cannot stand in practice.

For example, the magic-angle graphene that Wang Xuan is studying.

It is absolutely established in theory, and it is at the forefront of all graphene researchers in the world.

But there is no super-high-quality, or even perfect, graphene to prove his theory in practice.

So many people think that magic-angle graphene is just a scam, and there are many people who belittle Wang Xuan.

however……

If it is so easy for Jiangnan to produce super-perfect graphene, it will definitely overturn an era, promote the fourth industrial revolution of mankind, and change the world pattern.

"impossible!"

"This is absolutely impossible!"

"I have also paid attention to your experiment in Jiangnan, although it used the combination of materialization and explosion.

"But the actual operation is not complicated, and it takes a very short time, and it only takes a few hours to die!"

"How can you make such a large and perfect graphene in such a short time?"

"..."

Alex was the first to retort.

Not only him.

There are still many people who don't really believe it.

after all!

They are all experts and professors in physics.

Even if the research is not on graphene, it does not mean that they know nothing about graphene.

Several current techniques.

Making graphene is not only of poor quality, but also takes a long time, usually more than ten hours.

Even if a single-layer graphene is produced at an ultra-high speed, it cannot be formed in an hour.

Even if it is formed.

The thickness of single-layer graphene is less than one nanometer, and it cannot be seen or touched by the naked eye. Only 20 pieces of graphene are added together to be as thick as a hair.

But what about the graphene in Jiangnan's hands?

It's the size of a thumb.

And it's perfect graphene.

This is going to crush their cognition!
but……

No matter how much they don't believe it, it's useless.

Because soon they will have to believe it.

If there is anyone present who is most excited about the appearance of perfect graphene, it is definitely Wang Xuan.

At the same time, there is no shortage of experts and professors who have researched graphene in the physics organizing committee, and they immediately judged the graphene in Jiangnan's hands.

First of all, it is certain that this is definitely graphene.

As for the quality.

They first used several simple methods.

First, although the general point of graphene is also colorless, its light transmittance is only 90.00% 100, which is not [-]% transparent, but theoretically perfect graphene can do it.

This is well verified.

Everyone took the graphene crystal in Jiangnan's hand to verify it, and immediately came to a conclusion that the light transmittance was [-]%.

Second, all substances in the world have electrostatic reactions, and the electrostatic reactions of general graphene are very small, so small that they can be ignored, but they cannot 100% isolate static electricity.

however……

In theory, perfect graphene can.

Wang Xuan took Jiangnan's graphene crystal and rubbed it against his clothes dozens of times, then pulled a strand of hair and put it together, and found that there was no reaction at all.

This is the end.

The faces of all the people present changed.

Because these two simple test methods do not 100% prove that the graphene produced by Jiangnan is perfect graphene, but it is enough to prove that it is of extremely high quality.

Much higher than the graphene produced by the previous production process, it has reached the point where it is difficult to distinguish with the naked eye.

And next.

Wang Xuan and several physics teachers who have experienced research on graphene also verified the basic properties of this piece of graphene, such as strength, toughness, electrical conductivity and thermal conductivity.

Ordinary graphene is already the strongest, toughest, and most conductive and thermally conductive thing in the world.

The perfect graphene is even better, and can even achieve 100% electrical and thermal conductivity.

after verification.

This piece of graphene in Jiangnan meets the theoretical standards.

Some don't even give up.

Microscopic method, spectroscopic method, mechanical performance test, thermal performance and thermal effect analysis were carried out on it in turn...

Anyway, this is Harvard's physics experiment building.

All the necessary instruments are available.

In short, it was a fierce operation, until everyone finally concluded that this is the perfect graphene.

"Hahaha!"

"The perfect graphene can finally be produced in this world, so I can finally conduct the magic-angle graphene experiment!"

"I can finally prove to the world that the magic-angle graphene theory is feasible, and this is not a hoax!"

Wang Xuan burst into tears.

That's because he was too excited.

And Alex, those who had misunderstood Jiangnan before, lowered their heads one after another, "Student Jiangnan, I'm sorry, your experiment was successful, you really improved the manufacturing method of new materials, and even created a perfect Graphene!"

"It can be said……"

"Your actions will change the world!"

"Our organizing committee made a mistake, and I would like to express my sincerest apologies to you, and hope to obtain your forgiveness!"

"..."

"I don't forgive you, put it aside for now. In this physical competition, are you going to give me the points you should have?"

"Give, must give!"

"How many?"

"48 points, it must be 48 points!"

Alex's eyes widened, and he said with certainty: "Score 24 in the science test, and the experimental part, with this perfect piece of graphene, must also be 24 points. Anyone who dares to object to me is in a hurry!"
