Xueba's Sea of ​​Stars

Chapter 187 Let's write a paper first
"You are really capable..."

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

The resources of the School of Physics of HKUST are the most abundant in the whole school. Correspondingly, the difficulty of the courses is also the highest in the school. Many students of the School of Physics will take a course called "Tea and Health" in the second half of their freshman semester or their sophomore year, or simply I turned to philosophy halfway.

But the one in front of him is good. He hasn't failed in any of his professional courses, and he still has time to ask him about materials that he is simply interested in.

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

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

Liu Yubo squinted his eyes and nodded, looked at Wu Bin with a smile from someone who had come here, and said, "You are now doubtful 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 to me. If the writing is good enough, it is not impossible for you to join my experimental team."

"Huh?" Wu Bin was taken aback after hearing this, "Will you write something that is within my understanding?"

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

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

Although I don't know why, but Liu Yubo insisted that Wu Bin felt that he had earned it.

Lin Ziqi behind Wu Bin was in a daze. She obviously just wanted to hear about the magic of this material, so there was an extra homework for no reason! ?

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

"Tsk, he took me as a tonic..."

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 material science is far from as simple as he imagined.

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

……

"Are you really planning to write a thesis report?" Lin Ziqi asked Wu Bin as soon as she left the classroom.

"Yes." Wu Bin nodded.

"You wrote it?"

"No."

"..."

Looking at Lin Ziqi's speechless expression, Wu Bin comforted him: "Sooner or later, papers are written. In fact, the reason I study graphene is to write papers."

Lin Ziqi: "But I can't at all..."

"I'll teach you, read two more papers, and you can learn it easily."

Sighing, looking at Wu Bin, Lin Ziqi nodded, "Okay, then I'll ask Professor Wu for 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 can complete a thesis independently in her freshman year, or even join Professor Liu's experimental team, it will 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 followed along! '

Lin Ziqi became proud for a while.

As a strong girl, Lin Ziqi followed Wu Bin in the library from the next day, reading 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 to before.

With the passing of such fulfilling days, Wu Bin had his own insights on the preparation method of graphene, and began to work on the part of the thesis.

【Graphene preparation method and research progress】

【Abstract】In recent years, graphene, with its unique structure and excellent material

It is widely used in the fields of physics, chemistry and materials science.Referring to the latest reference materials, the preparation methods of graphene are reviewed, such as epitaxial growth, vapor deposition, mechanical exfoliation, redox and other methods, and the research progress and future development direction 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 that of real graphene, as is the price.

Many promotional words that claim to be able to mass-produce graphene cheaply actually refer to materials similar to graphene oxide, comparable to Li Kui and Li Gui.

"Huh...Wu Bin, do you see the schematic diagram of the molecular structure of RGO drawn like this?"

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 prepared graphene by bombarding ethanol droplets with argon atoms in a microwave environment under normal pressure and without using substrate materials. The method made Wu Bin feel very interesting.

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

……

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

In the conclusion of the thesis, 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.

However, the new preparation methods are all working towards the same direction, that is, simple, safe, efficient preparation process and easy-to-apply preparation products.Only when these requirements are met, can graphene be more widely used and move towards industrialization.

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

For a thesis report of about 80 words, Wu Bin referred to more than [-] literatures. 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?" Wu Bin asked Lin Ziqi next to him in a low voice after filing his thesis.

"Woo~" Looking at Wu Bin's face, Lin Ziqi felt like crying.

"Well, I'll give you three chances to ask questions, and the scope should not be too large, how about it?"

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

"Only three times, don't bargain." Wu Bin resolutely refused.

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

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

"All right……"

Lin Ziqi didn't continue to make more efforts, after all, she already knew that for Wu Bin, it was useless to be cute or pitiful, this guy didn't think of himself as a poor and helpless little girl!
