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

Abi Moyle felt that because this paper was submitted with Shengzhou University as the communication unit, Qiu Chengtong should not have read this paper before.

As long as the name of the author of the paper is hidden and Qiu Chengtong is used as a reviewer, there won't be much of a problem.

After all, you can't just pass the paper just because other reviewers can't understand it.

But Abi Moyle never expected that Qiu Chengtong would directly guess the author of this paper.

When something like this happens, the next step of review work becomes even more difficult.

In desperation, Abi Moyle had to report the situation to the editor-in-chief of the Journal of the American Mathematical Society.

After learning about this situation, the editor-in-chief of the journal also felt a little overwhelmed.

After thinking for a while, the editor asked:

"Abi, has Qiu Chengtong read this paper before, or did you guess the author's identity from the content of the paper?"

"Well... the author's identity should be guessed from the paper. Otherwise, there is no need for him to ask us if the author of this paper is Ning Chen."

"If this is the case, it is still an acceptable result. Since Professor Qiu Chengtong asked this question, it means that at least he has not read this paper before, and he does not want to affect the review because of his relationship with Ning Chen fairness."

"Then... we should let Professor Qiu Chengtong continue to review this paper?"

"Yes, it is not easy to find people around the world who can understand this paper. Abi, just reply to Professor Qiu Chengtong like this. You don't need to care about who the author of this paper is, just evaluate it. The content of a paper is enough.”

Anyway, there are at least three reviewers for a paper. Even if the relationship between Qiu Chengtong and Ning Chen may affect the fairness of the review of this paper, the opinions of other reviewers can be given priority for reference.

And they also believe that with Qiu Chengtong's character, he will definitely review this paper normally.

"Okay, editor-in-chief, then I will reply according to your opinions."

When he received another reply email from the Journal of the American Mathematical Society, Qiu Chengtong also felt a little confused about the idea of ​​​​the journal.

"It seems... I have to review this paper."

In fact, in the past few days, although Qiu Chengtong has given up being a reviewer of this paper, Qiu Chengtong has been studying the content of this paper.

Qiu Chengtong did not go to confirm with Ning Chen, because once it was confirmed that the paper came from Ning Chen, Qiu Chengtong would really not be able to review the manuscript completely objectively.

Qiu Chengtong felt that he might as well not care so much and just treat it as a paper written by someone he didn't know at all.

In the days that followed, Qiu Chengtong put a lot of his energy into the research of this paper.

In fact, the complexity of this paper does not just lie in the mathematical part.

In addition to various obscure mathematical theories, the paper also involves a lot of advanced physics knowledge.

If you are not a reviewer who is very good at mathematics and physics, it is indeed difficult to fully understand the theories in the paper.

Fortunately, Qiu Chengtong himself is an expert in mathematics and physics, and Qiu Chengtong has done some research on the Navier-Stokes equation before, so he will not be unable to understand the content of the paper.

Finally, after days of review, Qiu Chengtong came to his conclusion.

"There are no problems with all the theories and proofs in the paper. This is an excellent paper!"

Although this paper has not completely solved the problem of existence and smoothness of the Navier-Stokes equation, it has solved an important classification of the problem, which can be regarded as a review of the Navier-Stokes equation. A very successful exploration.

Qiu Chengtong even felt that the research value of this paper was even comparable to the sum of Ning Chen's three previous papers that solved Qiu Chengtong's conjecture.

After sending his review comments to the Journal of the American Mathematical Society, Qiu Chengtong leaned back on his chair and exhaled heavily.

If this paper can be successfully published, Qiu Chengtong will know whether the author of this paper is really Ning Chen.

Shengzhou University, Materials Laboratory.

Ning Chen took the experimental plan he had compiled and handed it to Xu Zhou.

After these days of research, Ning Chen has found some new ideas for studying TiO2 nanotube arrays, which can theoretically improve some properties of TiO2 nanotube arrays.

After seeing Ning Chen's experimental plan, Xu Zhou asked in surprise:

"Ning Chen, do you want to add Ag+ again this time?"

Ning Chen had used a similar experimental plan before when studying porous silicon nanostructures.

"Yes, Teacher Xu, this is the experimental plan I predicted after analyzing the material structure. Of course, this is not directly related to that research topic, and the role Ag+ plays in it is completely different. .”

Next, Ning Chen continued to explain to Xu Zhou why he designed the experiment in this way.

"After Ag+ is introduced into the TiO2 photocatalytic system, Ag+ can capture photo-generated electrons, thereby acting as a receiver, prompting the photo-generated electrons to accumulate on the metal surface, while holes remain on the TiO2 surface, reducing the recombination rate of photo-generated electrons and holes At the same time, it also improves the photocatalytic activity of the TiO2 nanotube array..."

After listening to Ning Chen's explanation, Xu Zhou gradually understood Ning Chen's thoughts.

"I see. In fact, other precious metal ions should have the same role as Ag+ in this, right?"

"Yes, this is a change caused by the difference in Fermi level. But compared to other precious metal particles, Ag+ is cheaper, so it is more suitable as a dopant for TiO2 nanotube arrays."

If Au ions or Pt ions are used, although the experimental cost is within an acceptable range, the application cost is too different.

After confirming that Ning Chen's idea was feasible, Xu Zhou said with appreciation:

"Ning Chen, I didn't expect you to come up with such a great idea so quickly when I just gave you a research topic. Next, you can prepare for the experiment. If you are willing, I also want to participate in this research topic with you. "

The research of nanomaterials is one of Xu Zhou's key research directions. Compared with the research of iron-based superconducting materials, Xu Zhou is also more interested in this research direction.

"Of course, Teacher Xu, you are better at nanomaterials. It would be great if you could participate."

In materials science, material design is not the only difficulty. The synthesis and preparation of materials is also very particular.

Ning Chen did not have any experience in the preparation of TiO2 nanotube arrays. With the addition of Xu Zhou, the progress of the experiment will definitely be much smoother.

After deciding on the experimental plan, the experiment officially started.

In addition to Xu Zhou, Sui Feng was also drawn into the project by Xu Zhou, because nanomaterials may be Sui Feng's research direction during his future doctoral period. Xu Zhou did not want Sui Feng to miss such a good opportunity to participate in the experiment.

After the subject experiment started, Xu Zhou first took Ning Chen and Sui Feng together to prepare the TiO2 nanotube array.

"At the current stage, our main methods for preparing TiO2 nanotube arrays include anodization, hydrothermal method, module synthesis, etc. We will be more familiar with these methods first, and then prepare Ag+-doped TiO2 nanotube arrays. , should also be changes based on these methods.”

Under the guidance of Xu Zhou, Ning Chen and Sui Feng tried to prepare TiO2 nanotube arrays through these methods.

Although Ning Chen and Sui Feng had no relevant experimental experience before, their experimental operations soon opened up a very obvious gap.

Sui Feng didn't have any psychological gap. Sui Feng had long since learned to lie down beside Ning Chen.

After practicing for a few days, Ning Chen felt that he had the ability to start the next experiment.

After making a specific plan for the next step, Ning Chen found Xu Zhou and said to Xu Zhou:

"Mr. Xu, next I want to use anodization to prepare Ag+-doped TiO2 nanotubes."

Hearing Ning Chen's words, Xu Zhou nodded and replied:

"Well, I also think it is possible to prepare Ag+-doped TiO2 nanotubes based on the anodizing method. But Ning Chen, do you want to directly apply the anodizing method used to prepare TiO2 nanotube arrays before, or based on this? What about making some changes?”
