Start as a top student and move towards the stars and the sea

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

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

"I've been busy doing experiments on materials recently, and I haven't studied mathematics for the time being."

"Experiments in 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 shown an unparalleled talent in mathematics. Logically speaking, there was no need to focus on other subjects.

"Yes, because I am currently studying a double major in materials and mathematics. I happened to have some ideas in the direction of materials and started working on a project. If there are any good mathematics research directions in the future, I will continue to do so. Research."

"As expected of Brother Chen, you can study two degrees at the same time with ease. Will you publish a paper in the field of materials again in a while?"

"Thank you for your kind words from Senior Brother Tong," Ning Chen said with a smile.

When they arrived at a restaurant outside the school, 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 study abroad in batches. There is also a new professor who is said to have been hired from Jinda University. It seems that our mathematics department at Shengzhou University, We really plan 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 more than just words.

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

Ning Chen recalled some of the recent changes that had taken place in the school and found that Shengzhou University was indeed developing in a good direction.

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

In terms of campus environment, some old buildings have begun to be repaired. Roads that have not been repaired in several years have begun to be repaired. Even minor problems in student dormitories have begun to be taken seriously by the school.

Ning Chen didn't know how big an impact he had on the changes he made to Shengzhou University, but Ning Chen sincerely hoped that his alma mater would become better and better.

"Brother Chen, would you like to drink something?"

"I won't drink. I still have some work to do in the evening."

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

"Okay, then I'll just drink two bottles by myself. I'm happy that I finally published my paper."

"Okay, then I'll get you a drink."

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

"Ning Chen, I am actually very grateful to you for being able to inspire me when I was in the most difficult time. Before you guided me, I was already on the verge of collapse. I feel that I have certain research capabilities. 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, but as long as we get through the most difficult moments, everything will suddenly become clearer.”

When Tong Yicheng listened to Ning Chen's words, he didn't sound like a junior fellow student at all, but rather like his own teacher.

But Ning Chen's words made Tong Yicheng very emotional after hearing them.

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

When other people encounter difficult problems, they may choose to skip and do other simpler questions, but not Tong Yicheng. It was this character that put Tong Yicheng 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 think 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!"

The meal didn't 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 various experimental data from previous experiments and studied them carefully.

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

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

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%, not to mention 100%.

But now, the success rate of synthesizing standard samples is only over 30%.

"No... maybe there are some fundamental problems in some part."

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 hypothesis I made at the beginning, the reason why boron particles are added to nano-silicon is to convert the intrinsic silicon nano-particles 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 adding 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 could it be possible to generate corresponding porous silicon nanoparticles.

Now it seems that if the range of boron addition ratio is expanded from the beginning, new discoveries may be made.

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 you have a better working condition.

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

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

This time, Ning Chen adjusted the boron addition ratio and exceeded the previous limit.

Ning Chen has not made adjustments to other conditions for the time being.

In this way, Ning Chen conducted experiments for another two days and took the prepared samples to the measurement center for TEM measurements.

TEM will work very well here, making it 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. However, after all, Ning Chen extended the range of boron addition to a wide range, and it was very normal that he did not synthesize a standard product.

Until Ning Chen measured the dozens of groups of products, he suddenly discovered that a hole-shaped product image appeared on the computer screen.
