Chapter 186 Tearing up the Nobel Prize

According to the academic paper "Majorana Fermions", Song Nanfeng gave Wu Bin several key opinions.

First of all, don't rush to do experiments before you understand and deeply understand the physical laws of the problem you want to study.

Many people only spend 20% of their time thinking and designing experimental plans, but spend 80% of their time in the laboratory.

However, as far as some senior scientists he knew, they spent 80% of their time thinking and designing experimental plans. After everything was straightened out, they spent 20% of their time doing experiments to prove their theories.

"Okay, let me tell you this first. The tutor you choose will naturally teach you the rest of the article writing stage."

Wu Bin: "Professor Liu?"

"Well, just go to him after you finish the preparations I mentioned, but I'm still curious, why are you suddenly interested in graphene?"

"Because... I think it can change the world."

"..."

Song Nanfeng: "Are you serious? This material was indeed popular when it was first discovered, but after many years, there is still no good practical application method, although this is a normal phenomenon."

"My sixth sense told me this was it."

"..."

After hearing this, Song Nanfeng decisively made a move to drive Wu Bin away: "Go, go, go and study it quickly. If you talk to me about the sixth sense next time you come here, I'll see if I don't slap you with the book!"

"Okay, goodbye Professor Song."

After saying that, Wu Bin quickly slipped away.

As for the material graphene, Wu Bin is almost certain that it must have some extraordinary function. Of course, it is definitely not a sixth sense, but a system that has been silent for nearly half a year. When he became interested in this material, he immediately climaxed. Sent him a mission.

You must know that Wu Bin has learned about many materials before, but he has never seen any other material that can make the system react like this. Therefore, graphene, a material recognized by the system, must have its special features.

With great curiosity, Wu Bin dove into the library.

Probably because it is a new material, there are not many books on graphene, so Wu Bin had to go to VIP to check it out for a while.

After a few days, Wu Bin had a relatively preliminary understanding of graphene, and he firmly believed that if this material was fully developed successfully, it would indeed have the ability to change the world.

Graphene is essentially a two-dimensional carbon nanomaterial composed of carbon atoms with sp hybrid orbitals forming a hexagonal honeycomb lattice. It is the thinnest, strongest, most conductive and thermally conductive new nanomaterial currently found on the earth. .

It itself is only one layer of atoms thick, but is 200 times stronger than the best steel in the world.

It is also very simple to understand its origin.

[Graphite] I believe everyone has come into contact with it. The pencils used for writing are made of it.

And this graphene, which is only atomically thick, is peeled off from it. One millimeter of graphite contains almost 3 million layers of graphene.

In addition, the process of its birth can be said to be very "legendary"

Its nickname is "super material ripped out of tape."

That's right, graphene is stuck from graphite with tape.

Of course, this is only what it looks like on the surface.

In fact, the graphite used is very particular in the way it is adhered, and the tape used is not an ordinary tape, but a conductive tape.

This seemingly simple and crude method, but actually very clever, was discovered by Andre Geim, a physicist at the University of Manchester in the UK.

The principle used is that a single layer of graphite has strong exfoliation properties.

Why do we say the method is brilliant? That is because many scientists have actually thought about peeling off this layer of graphene, and have also used various high-tech methods to polish the graphite.

But the result is that the thinnest graphite sheet is still 1,000 carbon atoms thick. You must know that graphene with a thickness of more than 10 carbon atoms is considered a defective product. A sheet with a thickness of 1,000 carbon atoms can naturally be said to be a "waste product."

After Andre Geim carefully thought about the characteristics of this expected material for a long time, he came up with this method of sticking a single layer of graphene with tape.

And this tear resulted in a Nobel Prize.

The material containing the Nobel Prize was naturally hyped by all media.

It is said that it has important application prospects in terms of optical, electrical and mechanical properties, materials science, micro-nano processing, energy, biomedicine and drug delivery.

It is a super material that can change the 21st century.

In fact, the media is not completely boasting. An almost omnipotent material like graphene does have very good application prospects in various fields.

But now there is a very troublesome threshold blocking this material, that is, it cannot be mass-produced cheaply.

Take graphene batteries, which are currently the most popular, as an example. Graphene plays a role as a conductive agent and as an electrode lithium-embedded material.

But its "competitors" are graphite and conductive carbon respectively.

The price of the latter is not expensive even if it is sold per ton, but what about graphene? This is the material that Lun Ke comes to sell! There's also a hell of a lot of competitiveness.

So now graphene can only be studied in various possibilities in the laboratory. If it wants to be completely popularized, the bottleneck of mass production must be broken through first.

"Is it still one step away from changing the world?" Wu Bin closed his eyes and fell into deep thought after reading another paper on the research and development of graphene semiconductor optoelectronic devices.

While he was deep in thought, Wu Bin felt his phone vibrating in his pocket. He took it out and saw that the message was from Lin Ziqi, asking him if he wanted to go to the next big class with him.

Wu Bin replied "Go" to her and walked out of the library with questions.

…

"It's rare to see you absent-minded in class. What are you thinking about?"

After class, Lin Ziqi asked Wu Bin, who was still frowning.

Wu Bin: "Oh, I have been studying graphene recently and have been thinking about entry points."

Lin Ziqi: "Graphene? Aren't many people saying this is just a big bubble, thrown out to cut leeks?"

Wu Bin couldn't help but roll his eyes at Lin Ziqi and said: "What kind of research is there to follow what others say? Plastic was questioned for a long time when it first came out. Although it has many problems now, it does not affect the fact that it is indeed omnipotent."

"Okay." Lin Ziqi stuck out her tongue after being scolded, "How is your research going?"

"At the beginning, I saw that there is still a lot to learn. I am going to ask Professor Liu tomorrow. I heard Professor Song say that he is an expert in this field."

"Then...can I go and listen together?"

"Huh? Are you also interested in graphene?" Wu Bin was a little surprised.

Lin Ziqi couldn't help but sigh, and said helplessly: "Yes, I became interested after hearing what you said!"

"Okay, I'll go to the library later and I'll show you some papers that I've read and think are valuable. I guarantee you'll like them!"

Lin Ziqi kept nodding her head and said, "Yes, yes, I like to read the paper you gave me the most."

"That's right, when has the paper I introduced to you not been a top-notch one? Go quickly, go quickly."
