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

Chapter 74 Maybe there is more than one kind

Ning Chen will keep this journal in his study as a souvenir.

"Brother Chen, what have you been up to lately? I haven't been to our laboratory for a long time."

"Recently, I'm busy doing experiments on materials, and I haven't studied mathematics yet."

"Experiments on materials? Do you really want to develop in the direction of materials?"

Tong Yicheng didn't quite understand this. After all, Ning Chen had already demonstrated an unparalleled talent in mathematics, so there was no need to focus on other subjects.

"Yes, because I am studying a double degree in materials and mathematics. I happened to have some ideas on the direction of materials, so I started to do a project. If there is any good direction in mathematics research, I will continue to do it Research."

"As expected of Brother Chen, you can do it with ease while taking two degrees at the same time. After a while, you will publish a paper in the field of materials again, right?"

"Brother Tong's good words." Ning Chen said with a smile.

Arriving at a restaurant off campus, the two ordered a few dishes and chatted while waiting.

"Brother Chen, there have been some changes in our mathematics department recently. The teachers are going to go outside for further study in batches. There is also a new professor who is said to be recruited from Jinda University. It seems that the mathematics department of Shengzhou University, It is really planned to develop well.”

Among the various majors at Shengzhou University this year, the one with the largest score increase was the Department of Mathematics.

Ning Chenxin said that the promises Dean Liu made at the dinner were really not just words.

"Well, this is a good signal. I believe that Shengzhou University will emerge more outstanding talents in the future."

Ning Chen recalled some recent changes in the school, and found that Shengzhou University is indeed developing in a good direction.

The materials laboratory has also newly purchased some cutting-edge equipment, which can support many high-end experiments and greatly improve the measurement accuracy of the experiments.

In terms of the campus environment, some old buildings have started to be repaired, and roads that have not been repaired for several years have been repaired. Even the various minor problems in the student dormitory have begun to be taken seriously by the school.

Ning Chen didn't know how much influence he had on Shengzhou University's changes, but Ning Chen sincerely hoped that his alma mater would become better and better.

"Brother Chen, would you like a drink?"

"I won't drink, I still have some work to do at night."

Ning Chen hoped that he could keep a clear mind, so he politely declined Tong Yicheng's invitation.

"Okay, then I'll drink two bottles by myself, and I'm happy to finally publish the paper."

"Okay, then I'll accompany you with a drink."

After several glasses of beer, Tong Yicheng's face turned rosy.

"Ning Chen, in fact, I am really grateful to you for being able to inspire me in my most difficult times. Before you guided me, I was already on the verge of collapse. I feel that I have a certain research ability. But I still can't break through that bottleneck..."

Tong Yicheng was a little excited, but Ning Chen could also understand Tong Yicheng's mood.

"Senior Brother Tong, these are all normal things. I haven't made any breakthroughs in the material experiments I've done recently. I think you are indeed one of the more capable students in the Mathematics Department of Shengzhou University. Sometimes We may be one step away from success, as long as we get through the most difficult moments, everything will suddenly become clear."

Listening to Ning Chen's tone of voice, Tong Yicheng didn't look like a younger student at all, but rather like his teacher.

But Ning Chen's words made Tong Yicheng very touched after listening to them.

Ning Chen didn't try to comfort Tong Yicheng deliberately, Tong Yicheng gave Ning Chen the feeling that he was a top student who liked to solve difficult problems.

When other people encounter difficulties, they may choose to skip and do other simpler topics, but Tong Yicheng is not. It is this kind of character that made Tong Yicheng fall into the predicament at that time.

"Ning Chen, I hope that my next research project can be completed by myself." "Well, this is definitely the best. Of course, there is no problem with normal academic exchanges between us. Senior Brother Tong, you can often Thinking of some good research directions, I have to learn from you in this regard."

"Hey, don't be humble with me. Come on, let's go!"

This meal did not take too long. Tong Yicheng knew that Ning Chen still had work to do, so he was sorry to delay Ning Chen for too long.

After returning to the dormitory, Ning Chen found out all kinds of experimental data from the previous experiments and started to study them seriously.

"There are still some problems in the synthesis of porous silicon nanoparticles."

After summarizing the statistical experimental data, Ning Chen couldn't help sighing.

Although the synthesis success rate of standard samples has been slightly improved through process improvements, it is still far from meeting Ning Chen's requirements.

Normally, if the synthesis method of the sample is correct, the success rate of synthesis must be at least 90.00%, not to mention [-]%.

But now, the success rate of standard sample synthesis is only over 30.00%.

"No...Maybe in some part, there are some fundamental problems."

Thinking of this, Ning Chen first found out the TEM (transmission electron microscope) images of silicon nanoparticles at various stages that he had done before.

"According to the theoretical assumption I made at the beginning, the reason why boron particles are added to nano-silicon is to convert intrinsic silicon nanoparticles into p-type..."

Ning Chen analyzed the entire research topic from scratch and gradually found a new direction of thinking.

"So, in fact, there is not only one kind of porous structure of silicon nanoparticles? If the addition ratio of boron is changed, can new porous silicon nanoparticles be formed?"

At the beginning of the experiment, Ning Chen subconsciously controlled the addition ratio of boron within a fixed range, because Ning Chen felt that only within this range would it be possible to generate the corresponding porous silicon nanoparticles.

Now it seems that if the range of boron addition ratio is expanded at the beginning, maybe there will be new discoveries.

Ning Chen didn't feel upset about these things. After all, it was very normal to take some detours when exploring new things.

After determining the new direction, Ning Chen felt a little excited and wanted to go to the laboratory immediately to start experiments.

However, Ning Chen immediately suppressed the excitement and tried to calm down.

Only after adequate rest can we have a better working condition.

The next day, Ning Chen came to the laboratory early, put on a lab coat and started the experiment.

After staying in the laboratory for a long time, Xu Zhou gave Ning Chen the key to the laboratory, because Ning Chen was always the first to come and the last to leave.

This time, Ning Chen adjusted the proportion of boron added, breaking through the previous limit range.

For other conditions, Ning Chen has not made any adjustments for the time being.

In this way, Ning Chen conducted another two days of experiments, taking the finished samples to the measurement center for TEM measurements.

TEM works well here, as it is easier to show the porous structure of the material.

In the first few sets of measurements, Ning Chen did not find the ideal TEM image, but after all, Ning Chen extended the range of boron addition to a large range, and it is very normal that there is no synthetic standard product.

It wasn't until Ning Chen measured the dozens of groups of products that he suddenly discovered that an image of a product with holes appeared on the computer screen.
