According to the academic paper of Majorana Fermion, Song Nanfeng put forward several key opinions to Wu Bin.

First of all, don't rush to experiment until you understand and deeply understand the physical laws of the problem you are studying.

Many people spend only 20% of their time thinking and designing protocols, but 80% of their time in the lab.

However, as far as some senior scientists he knows, they spend 80% of their time thinking and designing experimental plans, and when they are all straightened out, they spend 20% of their time doing experiments to prove their theories.

"Okay, let's talk to you about this first, and the mentor you choose will naturally teach you the rest of the article writing stage."

Wu Bin: "Professor Liu?" ”

"Well, just wait until you're done with the pre-preparations I said, and then go to him, 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 blown into the sky when it was first discovered, but for many years, there is still no good practical application, although this is a normal phenomenon. ”

"Probably a sixth sense."

“……”

After hearing this, Song Nanfeng decisively made a driving action towards Wu Bin: "Go and go, hurry up and study you." ”

"Okay, goodbye, Professor Song."

For the material of graphene, Wu Bin can almost be sure that it must have some extraordinary effect, of course, it is definitely not the sixth sense, but the system that has been silent for nearly half a year immediately sent him a task as if he was interested in the material.

You must know that Wu Bin has also learned a lot of materials before, but he has not seen any other materials that can make the system react like this.

With great curiosity, Wu Bin plunged into the library.

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

After a few days, Wu Bin has a specific understanding of graphene, and is more determined that if this material is successfully developed, it does have the ability to change the world.

Graphene is essentially a two-dimensional carbon nanomaterial composed of carbon atoms with sp² hybrid orbitals, hexagonal and honeycomb lattice.

It is a new type of nanomaterial with the thinnest, strongest, and strongest electrical and thermal conductivity found on the earth.

It is only one atom thick, but it is 200 times stronger than the best steel in the world.

It's also easy to understand where it came from.

I'm sure everyone has come into contact with it, and the pencils used for writing are made of it.

And this graphene, which is only atomically thick, is stripped from it, and 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"

"Super material torn out with duct tape."

That's right, graphene is glued from graphite with adhesive 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 adhesive tape is not a general tape, but a conductive tape.

This seemingly simple and crude method, but in fact very clever, was discovered by physicist Andre Geim at the University of Manchester in the United Kingdom.

The principle of utilization is that graphite has strong peeling properties in a single layer.

The reason why the method is clever is that in fact, many scientists have thought about stripping out this layer of graphene, and have also used various high-tech means to polish graphite.

However, the thinnest graphite flakes obtained still have a thickness of 1000 carbon atoms, and graphene with a thickness of more than 10 carbon atoms is a defective product, and a flake with a thickness of 1000 carbon atoms can naturally be said to be a "waste product"

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

And this tear tore out a Nobel Prize.

contains materials from the Nobel Prize, which are naturally blown up by the media from all sides.

It is said that it has important application prospects in optical, electrical, 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 blowing, and almost all-round materials such as 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 graphene battery, which is currently the most blown, for example, graphene plays a role in it as a conductive agent and as a lithium intercalation material for electrodes.

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

The price of the latter is not expensive in terms of tons, but what about graphene? This is the material that Lunke is selling! There's also a ghost competitiveness.

Therefore, graphene is still a part that can only be studied in the laboratory with various possibilities, and in order to be completely popularized, the bottleneck of mass production must be broken through first.

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

While pondering, Wu Bin felt the mobile phone in his pocket vibrate, and when he touched it, he saw that the message was sent by Lin Ziqi, and asked him if he wanted to go with him in the next big class.

Wu Bin replied to her with a "go", and walked out of the library with questions.

"It's rare to see you absent-minded in class, what do you think?"

At the end of class, Lin Ziqi asked Wu Bin, who was still frowning.

Wu Bin: "Oh, I've been researching graphene recently, and I've been thinking about the entry point. ”

Lin Ziqi: "Graphene? It's not like a lot of people say it's a big bubble, thrown out to cut leeks. ”

Wu Bin couldn't help but glance at Lin Ziqi and said: "What else do people do to research, plastic was also questioned for a long time when it first came out, and now although it has a lot of problems, it is indeed very versatile." ”

"Okay." Lin Ziqi, who was trained, stuck out her tongue, "Then how are you studying?" ”

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

"That'...... Can I go and listen together? ”

"Huh? Are you also interested in graphene? "Wu Bin is a little strange.

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

"Okay, I'll show you a few papers I've read and think they're valuable."

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

"That is, which time is the paper I introduced to you that is not a good product, go quickly."
