Scholar’s Starry Sea

"You are so comfortable..."

Professor Liu Yubo, who is in charge of the condensed matter Physics class, squinted after listening to the question asked by Wu Bin. a smile.

University of Science and Technology has the richest resources in the school. Correspondingly, the difficulty of the course is also the highest in the school. Many students in the school will choose a course called [Tea and Health] class, or some simply turned to philosophy halfway.

But the one in front of him is not good. The grades of professional courses have not fallen. There is still time to ask him about the materials that he is only interested in.

"Are you the same as him?" Liu Yubo asked, looking at Lin Ziqi behind Wu Bin.

"Um...I am also interested." Lin Ziqi firmly nodded.

Liu Yubo squinted nodded, showed a smile from the person who came by, looked at Wu Bin and said: "You are now in doubt about the preparation method and difficulty of graphene, right?"

Wu Bin: "Yes."

"Okay, then you go back first, and each write a paper report on the preparation method of graphene to me. If you write well enough, let you join me The experimental team is not bad."

"Huh?" Wu Bin was taken aback after listening, "Write a copy of what I understand?"

"Of course." Liu Yubo nodded, "It's a topic I gave you."

"Okay, then I will go back and write now."

Although I don’t know why, Wu Bin Liu Yubo just said that there is a feeling that he has earned it.

Lin Ziqi behind Wu Bin has a dazed look. She obviously just wants to hear the magic of this material, why unfathomable mystery has one more assignment! ?

But before she was relieved, Wu Bin called out of the office.

"Hey, I was taken by him as a tonic when I dismissed Mawei..."

Liu Yubo actually didn't expect Wu Bin to answer so simply, he was originally I want to let Wu Bin bargain, and educate him myself to make him understand that material science is far from simple as he thought.

"This kid really can't handle it with common sense..." Liu Yubo took a sip of tea with emotion and continued to do his own thing.

……

"Do you really plan to write a thesis report?" Lin Ziqi stopped Wu Bin and asked as soon as he went out of teaching.

"Yes." Wu Bin nodded.

"Have you written?"

"No."

"..."

Looking at Lin Ziqi's speechless expression, Wu Bin comforted: "This thing is going to be written sooner or later. In fact, I study graphene to write a thesis."

Lin Ziqi: "But I don't know how..."

"I teach you, read two more papers, it is easy to learn."

sighed then said, glanced at Wu Bin, Lin Ziqi nodded, "Well, then please Wu Professor Lin Ziqi is very relieved of Wu Bin’s teaching level. In fact, after she calms down, she thinks carefully, if she can finish a thesis by her freshman year, or even join Professor Liu's experimental team, that was a very good experience.

In this way, Wu Bin will spend a lot more time together.

'Fortunately, I came with me! '

Lin Ziqi became proud for a while.

As a strong girl, Lin Ziqi also went to the library with Wu Bin the next day, and read various academic papers on graphene with Wu Bin.

In terms of professional courses, even if she is sometimes confused or unable to keep up with the progress, Wu Bin will patiently help her explain, and the learning efficiency can be said to have increased compared with before.

With the passing of such enriching days, Wu Bin has his own insights on the preparation of graphene and started to work on the thesis part.

[Preparation methods and research progress of graphene]

[Abstract: In recent years, graphene has been improved due to its unique structure and excellent material properties

It is widely used in the fields of Physics, Chemistry and materials science. With reference to the latest reference materials, the preparation methods of graphene, such as epitaxial growth, vapor deposition, mechanical exfoliation, redox, etc., are reviewed, and the research progress and future development directions of various preparation methods are discussed]

……

Wu Bin, the four most mainstream graphene preparation methods at present, has read a lot of literature, and finally reached a relatively superficial conclusion.

Not all graphite is called graphene.

Take the oxidation-reduction method as an example.

Refer to Hummers’ modified oxidation-reduction method, the preparation sequence is graphite→graphite oxide→graphene oxide→graphene

graphene oxide is also graphene, but the quality is the same as real graphene The gap is huge, and the same is true in terms of price.

Many promotional words that claim that graphene can be mass-produced at low cost are actually referring to materials similar to graphene oxide, comparable to Li Kui and Li Gui.

"Call...Wu Bin, do you think that the schematic diagram of RGO's molecular structure is drawn like this?"

Lin Ziqi asked Wu Bin in a low voice.

Wu Bin turned his head and glanced at Lin Ziqi's screen, and said: "I want to."

"Stingy..."

Since Lin Ziqi started to write After the thesis report, Wu Bin's help to her was drastically reduced. The purpose was naturally to exercise her own abilities, otherwise it would become Wu Bin's thesis instead of hers.

Ignoring Lin Ziqi’s aggrieved face, Wu Bin continues to look up more graphene preparation methods, including DaTo in a microwave environment under normal pressure and without using argon. The method of making graphene from atomic strikes and ethanol droplets made Wu Bin very interesting.

But if you want to get specific data, you have to go to the laboratory to test it.

……

About another week later, Wu Bin's first edition of the paper was finally completed.

At the end of the paper, Wu Bin wrote some of his own feelings, that is, according to the different application ranges and fields of graphene thin-layer materials, the preparation methods are also different.

But the new preparation methods are all moved towards the same direction, namely simple, safe and efficient preparation process and easy-to-apply preparation products. Only by meeting these requirements, can graphene be more widely used and move towards industrialization.

"Huh...The rest is to write down the references."

A paper report of about a thousand words, Wu Bin referred to more than 80 documents, It can be said that scientific research is really the power of everyone.

Without the foundation accumulated by so many people, how about a breakthrough!

"How is your progress?" After saving his paper, Wu Bin whispered Lin Ziqi next to it.

"wu~" Lin Ziqi looked at Wu Bin's face and felt like crying.

"Well, let me give you three chances to ask questions, how about the scope not too big?"

After listening, Lin Ziqi immediately stretched out five fingers and said:'Five times ! '

"Just three times, don't bargain." Wu Bin decisively refused.

Lin Ziqi thought about it after listening, then pointed to his thick dark circles and said, "Five times!"

"Just three times." Wu Bin still shook his head.

"Okay..."

Lin Ziqi doesn't continue to make more efforts. After all, she has known it a long time ago. For Wu Bin, whether it is cute or poor, Useless, this guy never thought of herself as a poor and helpless little girl!
