After all, Ning Chen can already be called a "god"-like existence in Shengzhou University.
Before the defense began, the three review teachers came to the classroom and sat down, making final preparations before the defense.
One of the teachers is Professor Yang Lianhua, whom Ning Chen is very familiar with.
Perhaps because Yang Lianhua and Ning Chen were familiar with each other, Yang Lianhua did not specifically greet Ning Chen, hoping to score each student's performance more objectively.
After the defense began, Ning Chen was the first to come to the podium.
This was also the order of defense specially arranged by the school before. Ning Chen could finish his defense earlier and leave earlier. After all, Ning Chen had to complete the defense of two majors and the task was heavier than that of other undergraduate graduates.
"Hello teachers, I am Ning Chen from Materials Class 0901. My defense topic is - "New Exact Solution to the Sine-Gordon Equation with Variable Coefficients"."
Hear Ning The other students in the classroom could not help but breathe a sigh of relief.
This is at least a research topic that they are likely to understand. If Ning Chen really talks about Qiu Chengtong's conjecture here, all the students will probably be confused.
The expressions of the three review teachers, including Yang Lianhua, were also slightly relaxed at this time.
After all, the research topic of Qiu Chengtong's conjecture is too complicated. Looking at the entire world of mathematics, there are only a handful of people who dare to say that they can fully understand the entire proof process of Ning Chen's Qiu Chengtong's conjecture.
Ning Chen’s defense process was very fluent. He explained the key points of his research content very well, and at the same time, he also controlled the speaking speed within a very appropriate range.
After experiencing many big events, Ning Chen did not feel any nervous about an undergraduate's graduation defense.
After Ning Chen finished describing his research results, the three defense teachers asked Ning Chen several questions about the research results, and Ning Chen also answered them fluently.
This forced the three review teachers to give Ning Chen the highest score.
"Okay, classmate Ning Chen, you still need to prepare for the defense of materials science, so you can leave first."
After thanking the three teachers, Ning Chen left the defense classroom .
With Ning Chen leaving, other students preparing for their defense felt even more nervous.
The defense that Ning Chen just conducted undoubtedly raised the standard of the entire defense to an extremely high level.
The second student who took the stage to answer the question clearly felt a lot of pressure.
Before this, he would never have believed that the person defending in front of him would be a Simmons Scholar Award winner.
As soon as he took the stage, he was so nervous that he almost forgot which class he was in.
This created a very strong contrast between him and Ning Chen.
……
After coming out of the mathematics defense classroom, Ning Chen did not rest, but immediately came to the materials major defense classroom.
Ning Chen's appearance once again attracted everyone's attention. Ning Chen was somewhat used to this situation, so he just found a place to sit down and waited quietly.
Since Ning Chen was participating in the undergraduate graduation defense as a sophomore and had to participate in the defense of two subjects in succession, the teacher did not make Ning Chen wait any longer.
After the last student’s defense, a review teacher said:
“Ning Chen, you will be the next one to defend.”
Ning Chen was very happy with this arrangement. He wouldn't gain much from watching other undergraduates' defenses.
Ning Chen’s defense process this time was still very smooth. After all, Ning Chen was very familiar with the content of his research process.
Coupled with several exercises before the defense, Ning Chen controlled his time very accurately.
After Ning Chen finished presenting his research results, a review teacher asked:
“Ning Chen, I am very interested in your research on porous nano-silicon materials. Interested. Can I ask, apart from the content shown in the PPT, is there any application space for this material?" Ning Chen was not sure whether the teacher really didn't know, or was just asking himself questions according to the process.
“When I studied this topic, I did not determine the application direction of this material. However, after that, I continued to conduct more in-depth research on the properties of this material.
Improving this material into a battery negative electrode and putting it into a lithium battery will make the lithium battery have a higher energy density.
Of course, at the same time, lithium batteries using this material as the negative electrode will also have a higher energy density. The lifespan will also be reduced, which is a problem that has not yet been solved.
Well... If you want to know more specific information, you can check the 18th issue of the main issue of "Nature" last year. That journal.”
Because the time to answer the questions was limited, Ning Chen was not able to give a specific and comprehensive answer.
After listening to Ning Chen’s answer, the three judges looked at each other and couldn’t help but smile.
You can ask a few questions at will, but you have to mention the application part. Isn't this forcing Ning Chen to come up with the research results of the paper published in "Nature".
None of these three reviewers have published "Nature" yet.
What they don’t know is that Ning Chen and Xu Zhou have actually solved the problem of low life of silicon-based lithium batteries.
Just because they signed a confidentiality agreement with Piati, the relevant results cannot be published publicly for the time being.
In the end, the three review teachers from the materials major also gave Ning Chen the highest defense score.
……
After completing the task of defending his undergraduate degree, Ning Chen continued to focus on research on superconductivity.
The results for the undergraduate graduation defense came out soon. Not surprisingly, Ning Chen ranked first in both the mathematics major and the materials major.
This allowed Ning Chen to win two more outstanding graduation thesis awards. Of course, for Ning Chen now, such awards would not make Ning Chen take it seriously.
However, Ning Chen took some time to attend the undergraduate graduation ceremony, wore bachelor's uniform and took some graduation photos.
There still needs to be a necessary sense of ritual, otherwise life will seem too monotonous.
Ning Chen’s three roommates acted as Ning Chen’s photographers. While they were happy that Ning Chen graduated from undergraduate school early, they were also a little sad about it.
After all, from now on, Ning Chen will no longer be a member of dormitory 208 and will enter the postgraduate stage.
"Brother Chen, we are only sophomores, and you have already graduated with a bachelor's degree. Alas...what will we do without you?"
Ning Chen heard this and said with a smile:
"Why, I'm a sophomore too, right? It's just that you have to go on to your junior and senior years, so I won't have a chance."
"Brother Chen, you are really murderous and heart-wrenching. But say Really, you graduated alone, and we still feel empty in our hearts."
"Yes, you will really not go back to dormitory 208, and you will no longer belong to the material class 0901."< br>
Looking at the expressions of Chen Tianpeng, Yang Yan, and Yuan Shuai, Ning Chen knew that they were really feeling a little sentimental.
After all, we have been roommates for two years, and the relationship between everyone is very sincere and pure.
Ning Chen is not sentimental. Really counting, these three people have been his roommates for six years.
“Hey, actually you don’t have to be like this. I just changed from an undergraduate to a graduate student, but I am still a student at Shengzhou University, and my major is still materials. We will definitely meet often in the future. .”
