Chapter 69 You may not believe it if you tell me
Hearing that Ning Chen would not help him with the experiment today, Sui Feng felt a little disappointed.
But this is Sui Feng’s own experiment after all. Ning Chen helps him out of love, but not helping him out of duty. Moreover, with Ning Chen’s ability, he will definitely not keep attacking others.
"Well, Teacher Xu is in the office next door, you 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 your recent internship in the laboratory these days?"
"It feels good. I learned a lot of things that I couldn't learn from textbooks. Now I can I have conducted some experiments independently. Thanks to Teacher Xu and Senior Brother Sui for their careful guidance."
Xu Zhouxin said that he actually did not teach Ning Chen much. As for Sui Feng... he almost regarded Ning Chen as free labor. used.
But from Ning Chen's perspective, this can indeed help Ning Chen become familiar with various experimental operations faster.
"Well, that's good. Ning Chen, tell me what you want from me."
"That's right, Teacher Xu, I have some new ideas during the experiment these days. I don't know if they are theoretically valid. I want to discuss them with you."
Hearing Ning Chen Xu Zhou also frowned.
This feeling is a bit like a player who has just participated in youth training and suddenly wants to participate in the competition. It makes people feel that the span is too big.
But after all, this was not the first time that Xu Zhou came into contact with Ning Chen. He knew that Ning Chen was a gifted student and he should never be viewed with ordinary eyes.
"Well, if you have any ideas, just tell me. I happen to have time now."
Xu Zhou asked Ning Chen to sit across from him. After Ning Chen sat down, he took out what he had recorded last night and handed it to Xu Zhou.
"Teacher Xu, I wrote a little hastily, so I'd better explain it to you in detail."
Ning Chen moved the chair next to Xu Zhou and looked at the draft The structural diagrams, reaction equations, and various calculation formulas on the paper were explained.
"The one on the far left is an ordinary silicon atom structure. The one in the middle is a silicon nanoparticle structure. The picture on the right is a porous silicon nanoparticle structure I imagined."
Ning Chen first explained the structural diagrams of the three previous silicon particles. Xu Zhou was no stranger to the first two structural diagrams, but it was the first time for Xu Zhou to see the third diagram.
"The structure of porous silicon nanoparticles... looks quite interesting."
Xu Zhou didn't know how Ning Chen imagined such a structure, but judging from the structure diagram alone, , and also has some aesthetic feeling of material structure.
Xuzhou made some rough calculations based on this structure, and was somewhat surprised to find that this structure is indeed reasonable in theory.
At least, it does not violate the various laws of materials science that Xuzhou can think of now.
It’s just that Xu Zhou still can’t figure out how Ning Chen could get such inspiration, whether this material can really be prepared, and whether it has any practical application value.
"Ning Chen, first tell me how you came up with the structural diagram of such a silicon particle."
"This...I don't know very well. Maybe it's because I usually like to think wildly. By chance, I thought of a structure similar to this. After thinking about it deeply, I found that this structure is still possible in theory. "
Ning Chen's reason sounds a bit forced. , but Xu Zhou didn't doubt anything. After all, the genius's ideas are difficult for ordinary people to understand.
“Judging from the basic particle structure theory, your silicon particle structure is indeed possible. Now what we have to consider is how to prepare it.”
Xu Zhou knew that just having an imaginary particle structure diagram was not enough.
But if Ning Chen could really prepare it, it would be enough to publish a good result.
"Teacher Xu, I also have some ideas about the preparation of this material."
"Huh? Let's talk about it." "First, we must choose silicon nanoparticles as the initial Raw materials. 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 purchased on the market, and it is also a variety of materials. A raw material not uncommon in experiments.
"Direct processing of silicon nanoparticles will definitely not allow them to form a porous structure. But if you add part of boron to them and then add an etchant to etch them, it is theoretically possible to create a porous structure... ”
Listening to Ning Chen’s explanation, Xu Zhou frowned and his brain was constantly thinking.
"Yes! According to your method, it is theoretically possible to create a hole structure in silicon nanoparticles. The step of adding boron is actually to convert the intrinsic silicon nanoparticles into p-type in theory. After etching , other ions in the silicon nanostructure will be removed, and what is left is naturally a porous structure..."
Xu Zhou was surprised to find that the entire material preparation process can be explained smoothly by theory, among which There are no obvious problems.
"Ning Chen, you are really smart. Why don't any of the other students in our experimental group be able to think of these wild hypotheses like you?"
Being praised by Xu Zhou in person, Ning Chen didn't dare to be proud.
“This is just a big problem in theory. In practice, there are still many problems to be solved.”
As an associate professor of materials science at Shengzhou University, Xu Zhou naturally also Know the difficulties.
“Yes, when we really want to start the experiment, 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, and what etchant should be used? What is matter, etc. This is still a question that we can think of at once. When we actually start the experiment, we will encounter more and more problems..."
At this time, Xu Zhou suddenly changed the subject. .
"However, I think this subject direction can be tried. Once we really achieve some results, maybe we can publish it in a district. Ning Chen, if you are willing, I will help you apply for this subject. We will start preparing to carry out the experiment.”
Ning Chen was waiting for Xu Zhou’s words. Seeing Xu Zhou’s willingness to apply for this project, Ning Chen suddenly became excited.
"Thank you, Teacher Xu. I also want to start experiments early. In the field of materials science, I haven't published a paper yet." Ning Chen said with a smile.
Xu Zhou was dumbfounded when he heard this. You are an undergraduate who has not yet entered your sophomore year. Normally you have not even taken professional courses. Why are you in such a hurry to publish your paper so early?
However, considering that Ning Chen has published two papers in the field of mathematics, Ning Chen’s words are really not just casual remarks.
"Then it's settled. Once the project application is completed, you will be fully responsible for the relevant experiments, and I will be your instructor. There are some experiments that you may not be able to handle alone, 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 how Sui Feng will feel when he experiences this change in identity.
......
After Ning Chen and Xu Zhou finished chatting, Xu Zhou helped Ning Chen apply for this project as promised.
Normally, Ning Chen's grade does not meet the conditions for applying for experimental projects. However, Ning Chen is not an ordinary student after all. The school deliberately applied for Ning Chen's project according to the standards of senior students and gave Ning Chen a certain amount of funding for the project. .
Even if the school specifically gave Ning Chen the green light, making the entire application process much faster, the necessary procedures still need to be completed.
Ning Chen couldn't help but sigh in his heart, it is easier to do research on mathematical problems. At most, he can use a computer. Sometimes a few pieces of scratch paper may be enough.
Fortunately, Xuzhou asked Ning Chen to start the experiment in advance without waiting for the formalities to be completed. Anyway, the raw materials used in the early stage of the experiment are all in the laboratory. At worst, they can just buy a batch later.
Before the experiment started, Xu Zhou called Ning Chen and Sui Feng together to prepare the next experimental plan.
Sui Feng knew that Ning Chen was going to start working on his own experimental project. Sui Feng was also a little surprised by this matter. After all, Ning Chen had only been in the laboratory for a few days, so the jump was a bit too big.
Of course, Sui Feng also noticed Ning Chen's talent. If Ning Chen wanted to develop in the direction of materials, sooner or later he would have to carry out his own project.
