Xueba's Sea of ​​Stars

Chapter 186
According to the academic paper of [Majorana Fermions], Song Nanfeng put forward several key opinions to Wu Bin.

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 knows, they spend 80% of their time on thinking and designing experimental plans, and when everything is straightened out, they spend 20% of their time doing experiments to prove his theory.

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

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 hyped when it was first discovered, but after many years, there is still no good practical application method, although this is also a normal phenomenon."

"My sixth sense told me this was it."

"..."

After hearing this, Song Nanfeng resolutely made a gesture of repelling Wu Bin: "Go, go, study it quickly, you will tell me about the sixth sense when you come next time, and see if I don't beat you with a book!"

"Okay, goodbye, Professor Song."

After Wu Bin finished speaking, he 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. Send him a mission.

You must know that Wu Bin has known a lot of materials before, but he has never seen any other material that can make the system respond like this, so graphene, a material recognized by the system, must have its special features.

With great curiosity, Wu Bin plunged 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 for a while.

After a few days, Wu Bin has a relatively preliminary understanding of graphene, and he firmly believes that if this material is fully developed, it does have the ability to change the world.

Graphene is essentially a two-dimensional carbon nanomaterial composed of carbon atoms with sp hybridized orbitals to form a hexagonal honeycomb lattice. It is a new type of nanomaterial with the thinnest strength and the strongest electrical and thermal conductivity found on the earth. .

It itself is just one atom thick, yet 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 pencil used for writing is made of it.

And this atom-thick graphene is peeled off from it, and one millimeter of graphite contains almost 300 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 glued from graphite with tape.

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

In fact, the graphite used is very particular about the sticking technique, and the sticky tape is not ordinary tape, but conductive tape.

This seemingly simple and crude method is actually very clever. It was discovered by Andre Game, a physicist at the University of Manchester in the United Kingdom.

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

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

However, the thinnest graphite sheet still has a thickness of 1000 carbon atoms. It is necessary to know that graphene with a thickness of more than 10 carbon atoms is a defective product, and a sheet with a thickness of 1000 carbon atoms can naturally be said to be "waste".

After thinking about the characteristics of this envisioned material for a long time, Andre Geim came up with this method of sticking out single-layer graphene with adhesive tape.

And this tearing, tore out a Nobel Prize.

The material containing the Nobel Prize background is naturally hyped by the media from all sides.

It is said that it has important application prospects in optical, electrical, and mechanical properties, as well as in 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 exaggerating. Almost all-round materials like graphene do have very good application prospects in various fields.

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

Take the most popular graphene battery as an example. Graphene plays a role in it as a conductive agent and as an electrode lithium intercalation material.

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

The price of the latter is not expensive even if it is sold by ton, but what about graphene?This is the material sold on grams!There is also a ghostly competition.

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 meditating, Wu Bin felt the phone in his pocket vibrate. He took it out and saw that the message was from Lin Ziqi, asking him if he would like to go to the next big class together.

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

……

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

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 it's just a big bubble, thrown out to cut leeks."

Wu Bin couldn't help giving Lin Ziqi a blank look, and said, "What research is there to follow others' advice? When plastic first came out, it was questioned for a long time. Although it has many problems now, it does not affect the fact that it is indeed omnipotent."

"Okay." Lin Ziqi, who was being trained, stuck out her tongue, "Then how is your research going?"

"At the beginning, I still have a lot to learn. I'm going to ask Professor Liu tomorrow. I heard that Professor Song said 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 sighing, and said helplessly, "Yes, I'm interested after hearing what you said!"

"That's fine, I'll go to the library later and I'll show you a few papers that I've read and thought were valuable, I'm sure you'll like them!"

Lin Ziqi kept nodding and said, "Yes, yes, I like reading the papers 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."
