"You're really at ease......"

Professor Liu Yubo, who was in charge of the condensed matter physics class, squinted and smiled after listening to Wu Bin's question.

Many students will take a course called "Tea and Health" in the second semester or sophomore year, or some simply switch to philosophy halfway.

But this is a good thing in front of him, he didn't fall behind in the professional course, and he still has time to ask him about the materials he is just interested in.

"You're like him?" Liu Yubo looked at Lin Ziqi behind Wu Bin and asked.

"Hmm...... I'm also interested. Lin Ziqi nodded firmly.

Liu Yubo squinted and nodded, showed a smile from the past, and then looked at Wu Bin and said, "You have doubts about the preparation method and difficulty of graphene now, right?" ”

Wu Bin: "Yes. ”

"Okay, then you go back first, and each of you will write a paper report on your graphene preparation method to me, if the writing is good enough, it is not impossible for you to join my experimental team."

“？” Wu Bin was stunned for a moment after hearing this, "Do you write a copy that I understand?" ”

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

"Okay, then I'll go back and write it now."

Although I don't know why, Wu Bin was told by Liu Yubo that he had earned it.

Lin Ziqi behind Wu Bin was confused, she obviously just wanted to hear the magic of this material, why did she have an extra homework for some reason!?

But before she could calm down, she was called out of the office by Wu Bin.

"Tsk, I'm being taken by him as a tonic this time......"

Liu Yubo actually didn't expect Wu Bin to answer so simply, originally he wanted to let Wu Bin bargain and educate him again, so that he could understand that materials science is far from being as simple as he imagined.

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

……

"Are you really going to write a dissertation report?" As soon as the teaching hug came out, Lin Ziqi grabbed Wu Bin and asked.

"yes." Wu Bin nodded.

"You wrote?"

"Nope."

“……”

Looking at Lin Ziqi's speechless expression, Wu Bin comforted: "There is such a thing as a paper, which has to be written sooner or later, in fact, I research graphene just to write a paper." ”

Lin Ziqi: "But I don't know ...... at all."

"I'll teach you, read two more papers, and it's easy to learn."

Sighing and glancing at Wu Bin, Lin Ziqi nodded, "Okay, then ask Professor Wu for more advice." ”

Lin Ziqi is still very relieved about Wu Bin's teaching level, in fact, after she calmed down, she thought about it carefully, if she could complete a paper independently in her freshman year, or even join Professor Liu's experimental team, it would be a very good experience.

And in this way, Wu Bin will spend a lot more time together, it's like killing many birds with one stone!

'Good thing I came along!' ’

Lin Ziqi became proud for a while.

As a strong girl, Lin Ziqi also followed Wu Bin to the library 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 be unabated compared with before.

As such fulfilling days passed, Wu Bin had his own opinions on the preparation method of graphene and began to work on the thesis part.

【Preparation method and research progress of graphene】

[Abstract: In recent years, graphene has been known for its unique structure and excellent material

Material properties are widely used in physics, chemistry and materials science and other fields. Referring to the latest bibliographic references, the preparation methods of graphene, such as epitaxial growth, vapor deposition, mechanical exfoliation, redox and other methods are reviewed, and the research progress and future development direction of various preparation methods are discussed.

……

Wu Bin has read a lot of literature on the four most mainstream graphene preparation methods, and finally came to a relatively superficial conclusion.

Not all graphite is called graphene.

Take redox as an example.

The modified redox method preparation sequence of Hummers is graphite → graphite oxide→ graphene oxide →graphene

Graphene oxide is also graphene, but the quality is very different from real graphene, and the same is true in terms of price.

Many promotional words that claim to be able to mass-produce graphene cheaply are actually talking about materials similar to graphene oxide, comparable to Li Kui and Li Ghost.

"Whew...... Wu Bin, are you right when you look at the schematic diagram of the molecular structure of RGO? ”

Lin Ziqi asked Wu Bin in a low voice.

Wu Bin turned his head to look at Lin Ziqi's screen and said, "Think for yourself." ”

"Stingy ......"

Since Lin Ziqi started writing her dissertation report, Wu Bin's help to her has decreased sharply, and the purpose is naturally to exercise her own ability, otherwise it will become Wu Bin's thesis, not hers.

Ignoring Lin Ziqi's aggrieved face, Wu Bin continued to consult more preparation methods of graphene, among which there was a method of preparing graphene by bombarding ethanol droplets with argon atoms in a microwave environment under atmospheric pressure and without using the base material, which Wu Bin found very interesting.

But if you want to get specific data, you have to go to the laboratory and conduct experiments.

……

After another week or so, the first version of Wu Bin's paper was finally completed.

Finally, in the conclusion of the paper, Wu Bin wrote some of his feelings, that is, according to the different application scope and field of graphene thin layer materials, the preparation methods are also different.

However, the new preparation methods all work in the same direction, that is, 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 the road to industrialization.

"Whew...... All that's left is to write down the references. ”

In a paper report of about 1,000 words, Wu Bin has referred to more than 80 literatures, and it can be said that scientific research is really a collection of people's strength.

Without the foundation accumulated by so many people, how can there be a breakthrough!

"How's your progress?" After archiving his paper, Wu Bin whispered to Lin Ziqi next to him.

"Woo~" Looking at Wu Bin's face, Lin Ziqi wanted to cry a little.

"Well, I'll give you three chances to ask questions, and the scope shouldn't be too big, how about it?"

After hearing this, 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 hearing this, and then pointed to her thick dark circles and said, "Five times!" ”

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

"Okay......"

Lin Ziqi didn't continue to work harder, after all, she already knew that for Wu Bin, whether it was cute or pitiful, it was useless, and this guy didn't think of himself as a poor and helpless little girl! 2k reading web
