Chapter 187 Let’s Write a Paper First

"You are really at ease..."

Professor Liu Yubo, who is in charge of the condensed matter physics class, narrowed his eyes and smiled after listening to Wu Bin’s questions.

The resources of the School of Physics at HKUST are the richest in the school. Correspondingly, the courses are also the most difficult in the school. Many students in the School of Physics will take a course called "Tea and Health" during the first half semester or sophomore year, or some simply I turned to philosophy halfway.

But the one in front of him was good. He didn't fail in any of the professional courses, and he still had time to ask questions about materials that he was simply interested in.

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

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

Liu Yubo squinted his eyes and nodded. He looked at Wu Bin with an experienced smile and said, "You are now confused 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 your graphene preparation method for me. If the writing is good enough, it is possible for you to join my experimental team."

"Huh?" Wu Bin was stunned after hearing this, "Write one that is within the scope of my understanding?"

"Of course." Liu Yubo nodded, "This is a topic I gave you."

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

Although he didn't know why, Wu Bin felt like he had earned it after being told by Liu Yubo.

Lin Ziqi, who was behind Wu Bin, looked confused. She obviously just wanted to hear the magic of this material, but why was there an additional homework for no reason! ?

But before she could recover, Wu Bin called her out of the office.

"Tsk, he took my power as a tonic..."

Liu Yubo actually didn't expect Wu Bin to answer so simply. Originally, he wanted to let Wu Bin bargain for a while, and then educate him himself to make him understand that materials science is far from being as simple as he imagined.

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

…

"Are you really going to write a thesis report?" Lin Ziqi grabbed Wu Bin and asked as soon as he came out of the teaching room.

"Yes." Wu Bin nodded.

"Have you ever written?"

"No."

"..."

Looking at Lin Ziqi's speechless expression, Wu Bin comforted him: "You have to write a paper sooner or later. In fact, I study graphene just to write a paper."

Lin Ziqi: "But I don't know how to do it at all..."

"I'll teach you. Read two more papers and you'll learn it easily."

Sighing and looking at Wu Bin, Lin Ziqi nodded, "Okay, then I'll ask Professor Wu for more advice."

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

And this way, Wu Bin will spend a lot more time together, killing two birds with one stone!

‘Fortunately, I came with you! ’

Lin Ziqi felt proud for a moment.

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

In terms of professional courses, even if she was sometimes confused or couldn't keep up with the progress, Wu Bin would patiently help her explain. It can be said that her learning efficiency has increased compared to before.

As such fulfilling days passed day by day, Wu Bin had his own insights into the graphene preparation method and began to work on the thesis part.

[Graphene preparation methods and research progress]

【Abstract: In recent years, graphene has attracted much attention due to its unique structure and excellent materials.

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

…

Wu Bin read a large amount of literature on the four most mainstream graphene preparation methods, and finally came to a relatively rough conclusion.

Not all graphite is called graphene.

Take the redox method as an example.

Referring to Hummers' modified redox method, the preparation sequence 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 slogans claiming that graphene can be mass-produced cheaply are actually talking about materials similar to graphene oxide, comparable to Li Kui and Li Gui.

"Huh...Wu Bin, do you think this is the correct diagram of the molecular structure of RGO?"

Lin Ziqi asked Wu Bin in a low voice.

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

"mean……"

Ever since Lin Ziqi started writing her thesis report, Wu Bin's help to her has decreased sharply. The purpose is naturally to train her own abilities, otherwise it will become Wu Bin's thesis, not hers.

Ignoring Lin Ziqi's aggrieved face, Wu Bin continued to look up more graphene preparation methods. Among them, DaTo produced graphene by bombarding ethanol droplets with argon atoms in a microwave environment under normal pressure and without using base materials. Wu Bin found the method very interesting.

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

…

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

In the conclusion of the paper, Wu Bin wrote some of his own feelings, that is, depending on the application scope and field of graphene thin-layer materials, the preparation methods are also different.

However, new preparation methods are all working in the same direction, that is, simple, safe, efficient preparation processes and easy-to-use preparation products. Only by meeting these requirements can graphene be more widely used and move towards industrialization.

"Huh... all that's left is to write down the references."

For a paper report of approximately 1,000 words, Wu Bin referred to more than 80 documents. It can be said that scientific research is really a collective effort.

Without the foundation accumulated by so many people, how can we talk about breakthroughs!

"How is your progress?" After archiving his paper, Wu Bin asked Lin Ziqi next to him in a low voice.

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

"Okay, how about I give you three opportunities to ask questions, but the scope shouldn't be too large?"

After hearing this, Lin Ziqi immediately stretched out five fingers and said: ‘Five times! ’

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

After hearing this, Lin Ziqi thought for a while, then pointed to her thick dark circles and said, "Five times!"

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

"All right……"

Lin Ziqi didn't continue to make more efforts. After all, she had known for a long time that for Wu Bin, no matter how cute or pitiful he was, it had no effect. This guy didn't regard himself as a pitiful and helpless little girl!
