Scholar’s Starry Sea

According to [Majorana Fermion]’s academic paper, Song Nanfeng gave Wu Bin several key opinions.

First of all, don't rush to do experiments before you have understood and deeply understood the Physics law of the problem to be studied.

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

However, as far as some senior scientists he knows are concerned, they spend 80% of their time on thinking and designing experimental plans. After all, they are straightened out, and then 20% of their time is used to prove the experiment. His theory.

"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 Is it?"

"Well, wait until you finish the preparations I said before going to him, but I am still curious, why are you suddenly interested in graphene?"

p>

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

"..."

Song Nanfeng: "Are you serious? This material was just discovered It was really blown up at the time, but for many years, there is still no good practical application method, although this is also a normal phenomenon."

"My Sixth Sense told me that it was it. ."

"..."

After listening, Song Nanfeng decisively made a drive away to Wu Bin: "go go go, hurry up and study it, you come next time When you talk to me about Sixth Sense, let me see if I take the book to smoke you!"

"Okay, Professor Song, goodbye."

After talking about Wu Bin, he quickly slipped away. .

For the material of graphene, Wu Bin is almost certain that it must have an extraordinary effect. Of course, it must not rely on Sixth Sense, but the system that has been silent for nearly half a year. When he was interested, he immediately sent him a task as if he had a climax.

Be aware that Wu Bin has also learned a lot of materials before, but there is no other material that can make the system have such a reaction, so graphene, a material recognized by the system, must have its special Place.

With great curiosity, Wu Bin plunged into the library.

Probably because of the new material, there are not many books about graphene, so Wu Bin had to go to Weipu to check it for a while.

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

Graphene is essentially a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp² hybrid orbitals. It is currently the thinnest, strongest, and most conductive and thermally conductive material found on Earth. A strong new type of nano material.

It is only the thickness of an atom, but its strength 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, and the pencil used for writing is made of it.

And this atomic-thick graphene 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 torn out with tape."

Yes, graphene is glued from graphite with tape.

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

In fact, the graphite used is very particular about the sticking method, and the sticky tape is not a normal tape, but a conductive tape.

This seemingly simple and rude, but very brilliant method was discovered by Andre Gaim, a Physics scientist at the University of Manchester in the United Kingdom.

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

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

As a result, 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. A sheet with a thickness of 1000 carbon atoms is naturally fine. Said it is "scrap"

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

And this tear, tear out a Nobel Prize.

The material containing the Nobel origin is naturally a hype by various media.

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

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

Actually, the media is not completely bluffing. An almost all-round 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 is impossible to mass produce cheaply.

Take the graphene battery that has been blown the most at present. Graphene plays a role as a conductive agent and as an electrode lithium intercalation material.

But its "competitors" are graphite and conductive carbon.

The price of the latter is not expensive per ton, but what about graphene? This is the material that Lun Klai sells! There is also a ghostly competitiveness.

So now graphene is still a part of various probabilities that can only be studied in the laboratory. If you want to completely popularize it, mass production of this bottleneck must first break through.

"Is there one step away from changing the world?" Wu Bin, who finished reading another graphene semiconductor optoelectronic device research and development paper, closed his eyes and fell into contemplation.

While contemplating, Wu Bin felt the phone in his pocket tremble, and took a look. The message was sent by Lin Ziqi, asking him if he would go with him for the next big class.

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

……

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

When class is over, Lin Ziqi asks Wu Bin who is still browsing tightly knit .

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

Lin Ziqi: "Graphene? Not many people say this is a big bubble. , I threw it out to cut the leeks."

Wu Bin couldn't help Lin Ziqi with a white look, and said, "Yiyun still does some research. When plastic first came out, it has been questioned for a long time. There are also many problems, but it does not affect the fact that it is indeed very versatile."

"Okay." The trained Lin Ziqi stuck out his tongue, "Then how is your research?"

"At the beginning, there are still many places to learn. Tomorrow I am going to ask Professor Liu and I will hear Professor Song say that he is an expert in this area."

"That …Can I go and listen together?"

"en? Are you also interested in graphene?" Wu Bin was a little strange.

Lin Ziqi couldn't help sighed then said, and said helplessly: "Yes, I'm interested after listening to you!"

"That's OK, wait a moment I went to the library to show you a few papers that I had read and thought they were valuable, and I promise you would like them!"

Lin Ziqi kept nodded and said, "Yes, yes, I like to see you the most. Give me the paper."

"That is, which of the papers I introduced to you is not a high-quality paper, hurry up and go."
