Starting from a top student and marching towards the sea of ​​stars

Chapter 69 You may not believe it
Hearing that Ning Chen would not help him with the experiment today, Sui Feng felt a little disappointed.

But after all, this is Sui Feng's own experiment. It is out of love for Ning Chen to help him, and it is his duty not to help him. Besides, with Ning Chen's ability, he will definitely not keep helping others.

"Well, Mr. Xu is in the office next door, you can go find him."

Ning Chen came to the office next door, knocked on the door a few times, and after getting a response, opened the door and walked in.

"Ning Chen, you're here. How do you feel about being an intern in the laboratory these days?"

"I feel very good. I learned a lot of things that I couldn't learn in the textbooks. Now I can conduct some experiments independently. Thanks to Teacher Xu and Senior Brother Sui for their careful guidance."

Xu Zhouxin said that in fact, he didn't teach Ning Chen too much. As for Sui Feng... he almost used Ning Chen as free labor.

But from Ning Chen's point of view, this can indeed help Ning Chen get familiar with various experimental operations faster.

"Well, that's good. Ning Chen, tell me what you want from me."

"It's like this, Mr. Xu, I have some new ideas during the experiment these days. I don't know if it is theoretically valid. I want to discuss it with you."

Hearing Ning Chen's words, Xu Zhou also frowned.

This kind of feeling is a bit like a player who has just participated in the youth training and suddenly wants to participate in the competition. It makes people feel that the span is too big.

But after all, this is not the first time Xu Zhou has come into contact with Ning Chen. He knows that Ning Chen is an exceptionally gifted student, so he must not be viewed with the eyes of an ordinary person.

"Well, if you have any ideas, just tell me, I just happen to have time now."

Xu Zhou asked Ning Chen to sit on the seat opposite to him. After Ning Chen sat down, he took out the things recorded last night and handed them to Xu Zhou.

"Mr. Xu, I wrote it in a hurry, so let me explain it to you in detail."

Ning Chen moved the chair to Xu Zhou's side, and explained to the structure diagrams, reaction equations, and various calculation formulas on the draft paper.

"The one on the far left is the ordinary silicon atomic structure. The one in the middle is the silicon nanoparticle structure. The picture on the right is my hypothetical porous silicon nanoparticle structure."

Ning Chen first explained the structural diagrams of the first three types of silicon particles. Xu Zhou was no stranger to the first two structural diagrams, but it was the first time Xu Zhou had seen the third diagram.

"The porous silicon nanoparticle structure... looks interesting."

Xu Zhou didn't know how Ning Chen imagined such a structure, but just looking at the structure diagram, it still has some aesthetic feeling of material structure.

Xu Zhou made some rough calculations based on this structure, and was a little surprised to find that this structure is indeed reasonable in theory.

At least, it does not violate the laws of material science that Xu Zhou can think of now.

It's just that Xu Zhou still couldn't figure out how Ning Chen could get such an inspiration, and whether this material could really be prepared, and whether it had any practical application value.

"Ning Chen, first tell me how you came up with the structure diagram of such a silicon particle."

"This... I don't know too well. Maybe it's because I like to think wildly. Once by chance, I thought of a structure similar to this. After I thought about it deeply, I found that this structure is still theoretically possible. possible."

Ning Chen's reason sounds a bit forced, but Xu Zhou didn't doubt anything, after all, the way of thinking of a genius is hard for ordinary people to understand.

"Judging from the basic particle structure theory, your silicon particle structure is indeed possible. Now we have to consider how to prepare it."

Xu Zhou knew that just having an imaginary particle structure diagram was not enough.

But if Ning Chen can really prepare it, it will be enough to publish a good result.

"Mr. Xu, I also have some ideas about the preparation of this material."

"Huh? Let's talk about it." "First, we need to choose silicon nanoparticles as the initial raw material. In the selection of silicon nanoparticles, try to choose silicon nanoparticles with a particle diameter of less than 200nm."

Nano-silicon is a raw material that can be bought on the market, and it is also a kind of raw material that is not uncommon in various material experiments.

"Directly processing silicon nanoparticles will certainly not allow them to form a porous structure. But if some boron is added to it, and then an etchant is added to etch it, it is theoretically possible to make it produce a porous structure... "

Listening to Ning Chen's explanation, Xu Zhou frowned and his brain kept thinking.

"That's right! According to your method, it is theoretically possible to make silicon nanoparticles produce a hole structure. The step of adding boron is theoretically to convert the intrinsic silicon nanoparticles into p-type. After etching, the silicon nanostructures The other ions are removed and what is left is naturally a porous structure..."

Xu Zhou was surprised to find that the entire preparation process of the material could be explained smoothly with theory, and there were no obvious problems in it.

"Ning Chen, you really have a brilliant mind. Why don't the other students in our experimental group think of these unconstrained hypotheses like you?"

Ning Chen didn't dare to be proud of Xu Zhou's face-to-face praise.

"It's just that there are no major problems in theory. In practice, there are still many problems to be solved."

As an associate professor of materials at Shengzhou University, Xu Zhou naturally knows the difficulties.

"Yes, when we really want to start experiments, there are still many problems that need to be solved. For example, what is the particle size of the silicon nanoparticles, what is the proportion of boron added, what is the material used for the etchant, and so on. This is a problem that we can think of immediately, and when we actually start experiments, we will only encounter more and more problems..."

At this time, Xu Zhou suddenly changed the subject.

"However, I think this topic can be tried. Once some results are achieved, maybe it can be posted to the first district. Ning Chen, if you want, I can help you apply for this topic. We will then start preparing for the experiment.”

Ning Chen was waiting for Xu Zhou's words. Seeing Xu Zhou's willingness to apply for this project, Ning Chen became excited.

"Thank you, Mr. Xu, I also want to start the experiment earlier. In the field of materials science, I haven't published a paper yet." Ning Chen said with a smile.

Xu Zhou didn't know whether to laugh or cry when he heard the words. You are an undergraduate student who hasn't even entered the sophomore year. Normally, you haven't even touched professional courses. Why are you so anxious to publish your paper so early.

But considering that Ning Chen has already published two papers in the field of mathematics, Ning Chen's words are really not just casual talk.

"Then it's settled. After the project application is completed, you will be fully responsible for the relevant experiments, and I will be your instructor. You may not be able to handle some experiments by yourself, so I will ask Sui Feng to help you."

Ning Chen also suddenly understood the meaning of Xu Zhou's words. Anyway, Ning Chen has been helping Sui Feng a lot these days, so it is natural for him to help Ning Chen again.

I just don't know what kind of mood Sui Feng will feel when he experiences this change of identity.

……

After Ning Chen finished chatting with Xu Zhou, Xu Zhou helped Ning Chen apply for this subject as promised.

Normally Ning Chen's grade does not meet the requirements for applying for the experimental project, but Ning Chen is not an ordinary student after all, the school deliberately applied for the project according to the standards of senior students, and gave Ning Chen a certain amount of funding for the project .

Even though the school specially gave Ning Chen the green light to make the application process of the whole project much faster, but the necessary procedures still need to be gone through.

Ning Chen couldn't help sighing in his heart, it would be easier to do research on mathematical problems, at most he would use a computer, and sometimes a few scraps of paper might be enough.

Fortunately, Xu Zhou asked Ning Chen to start the experiment ahead of time without waiting for the formalities to be completed. Anyway, the raw materials used in the early stage of the experiment are available in the laboratory, and at worst, he can buy a batch later.

Before the experiment started, Xu Zhou called Ning Chen and Sui Feng together to arrange the future experiment plan.

Sui Feng knew that Ning Chen was going to start his own experimental project, and Sui Feng was also a little surprised about this matter. After all, Ning Chen had only been in the laboratory for a few days, and the jump was too big.

Of course, Sui Feng also noticed Ning Chen's talent. If Ning Chen wants to develop in the direction of materials, sooner or later he will have to carry out his own research project.
