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

Chapter 71 You can’t say this to your mistress.
"It worked... I really succeeded!"

For so many days, Ning Chen has never felt so excited like this moment.

Even though the original intention of studying this topic is to find breakthroughs from the fragments of information provided by the system.

But most of the work was done by Ning Chen alone.

This full sense of accomplishment is indeed extremely enjoyable.

With the sample picture of the scanning electron microscope, Ning Chen found Xu Zhou and shared the good news with Xu Zhou.

"Ning Chen...did you really succeed?"

Looking carefully at the image of the sample scanned by the scanning electron microscope, Xu Zhou determined that this was the porous silicon nanoparticle that Ning Chen had imagined before.

You know, from when Ning Chen first entered the laboratory to when he finally produced the ideal product, it took just over a month.

At the same time, many students may only have a relatively preliminary understanding of the laboratory. Being able to complete their own experimental content step by step is already a good performance.

However, in such a short period of time, Ning Chen achieved results that many graduate students could not achieve, which was enough to shock Xu Zhou.

"Judging from the samples obtained so far, it can be considered a success. However, this is only the first time I have successfully made this standard sample. I don't know if this is an accident."

Xu Zhouxin said that regardless of whether it was accidental or not, as long as it is successfully made once, it is already a very good result.

The synthesis success rate of many materials is not very high. This is because the synthesis environment of these materials is relatively harsh. There may be a slight difference in humidity, temperature, or concentration of raw materials, which will affect the final experimental results.

In addition, there are many other factors, even the experimenters themselves may not be able to explain clearly, and they may even be dubbed "metaphysics".

"So, Ning Chen, let's go back and do a few more experiments to see how successful the material synthesis is."

Ning Chen also had the same idea as Xu Zhou. If it was true that the standard sample was made by accident, then there must be some problems with the synthesis conditions.

After going back, Ning Chen repeated the previous experiment again, because this experiment was more important, Xu Zhou also asked Sui Feng to join in, and used the same experimental conditions as Ning Chen to conduct the experiment.

After repeated experiments many times, Ning Chen summarized the success rate of the experiments and found that on average, only two or three times out of ten experiments could successfully prepare standard samples.

The success rate of Sui Feng's experiment is even lower, only one out of every ten times can be successful.

For such a result, Sui Feng expressed some puzzlement.

"It's strange. I strictly followed Ning Chen's experimental conditions, and I didn't make any mistakes during the experiment... Why is the success rate of the final experiment so much lower than Ning Chen's."

Xu Zhou was not surprised by such a result.

"This situation is normal. Experiments with materials are sometimes difficult to reproduce. If you use the same recipe, wouldn't the taste produced by different chefs be different?"

Hearing what Xu Zhou said, both Ning Chen and Sui Feng couldn't help laughing.

"So, Teacher Xu, I am the chef who is not good at cooking?"

"You can't say that. The same chef cooks a dish many times, and the taste may be different. Just like my wife's cooking, the same dish is sometimes made salty and sometimes bland... Hey, this is not a good idea Tell your mistresses."

Xu Zhou explained this matter in a joking tone. Of course, Ning Chen knew that there were many very detailed things in it.

For example, how to stir the sample when mixing the sample.

During the annealing process, the temperature and annealing time are precisely controlled.

Control of speed during centrifugation, various precautions when adding etchant, etc.

Every detail here may seem trivial and will not have much impact on the final experimental results.

But when all the details are put together, it is likely to make a qualitative difference.

At this time, Ning Chen felt a little fortunate that he didn't ask Sui Feng to help him with the experiment because he wanted to speed up the progress of the experiment.Otherwise, Ning Chen might not be able to make a standard sample right now.

"Okay, Sui Feng, go ahead and get busy with your experiments. I will discuss the current experimental phenomena with Ning Chen."

The progress of Sui Feng's experiments was indeed relatively fast. When Xu Zhou let him go, he didn't refuse.

"Okay, then I'll go over there first. If you need anything, come find me."

After Sui Feng left, Xu Zhou said to Ning Chen:

"Ning Chen, based on the current experimental results, it is enough to write a good paper. Of course, the research on this topic is far from complete. Now do you want to write a paper first, or continue to carry out the experiment? ?”

Ning Chen thought for a while and said:

"Mr. Xu, with my current achievements, what level of paper can I publish?"

"A journal at the level of "Nature" is probably not good enough. Although a new material has been synthesized, this material is relatively not so prominent. I am afraid it will not arouse the strong interest of their journal editors. Of course, I think that as long as the paper is written enough Excellent, posting an article in the first district is still very promising."

After all, Ning Chen synthesized a new material in a completely new way, and its academic value is self-evident.

"Teacher Xu, if I submit this paper, will the academic value of the subsequent research results decrease?"

"Well... this is also discussed on a case-by-case basis. I think there is no problem with your research direction. The current research results can focus on material synthesis, and subsequent research results will focus on properties and applications. If in the future In the experiments, the properties in your theory can really be realized, and based on these alone, it is very promising to publish a top journal."

"Okay, Teacher Xu, I understand. Then I will write a paper based on these results first, and then continue my own research."

Because there are systematic tasks, Ning Chen still hopes to write a paper first, submit it to an academic journal in a district, and continue to carry out the next experiment at the same time.

If not, then consider adding more research results to the paper.

"Okay, then let's start writing the thesis by hand. You have had two thesis writing experiences before. Although both are mathematics-oriented papers, there are similarities in them. I don't have anything to worry about when writing the thesis. .”

Xu Zhou only explained to Ning Chen some things that needed special attention when writing materials and papers, and left the rest to Ning Chen himself.

Ning Chen has long been ready to write a thesis. He has sorted out the relevant theories before and consulted enough literature.

This allowed Ning Chen to write the thesis very quickly. In a few days, he had already finished the first draft of the thesis and showed it to Xu Zhou.

"Ning Chen, your speed is okay."

Sighing at how fast Ning Chen wrote the paper, Xu Zhou continued to look at the contents of the paper.

Ning Chen's thesis was written very smoothly, highlighting the key content and innovative content of Ning Chen's research results, and the entire structure is also very complete.

Even though Xu Zhou had been mentally prepared before, he never expected that Ning Chen's thesis could be written at such a high level.

"Yes, I took a look at the key content and the general framework. It is indeed very well written, and I have not found any problems for the time being. Then I will look at the detailed content and formatting problems. If there are no problems, it will be OK. Start translating and selecting journals.”

"Ms. Xu, can you recommend some suitable journals for me to submit first? I want to see the paper format above, and I will directly follow this format when translating."

"Well, that's fine. Let me think about it... your article belongs to the research scope of nanomaterials. I think it is more appropriate to submit it to the journal "ACS Nano"."

""ACS Nano"? Teacher Xu, what is the approximate level of this journal?"

"A journal in the first SCI area, the impact factor in recent years is probably more than 13 points. The main research directions involved include chemical synthesis, physical chemistry, nanotechnology, etc. This journal is one of the largest in the world in the field of nanomaterials research. One of the top journals."

After listening to Xu Zhou's introduction, Ning Chen also felt that it would be more appropriate for him to submit to this journal.

"Okay, Teacher Xu, then I will translate it according to the format of this journal first. If you find anything that needs to be revised in my paper, please contact me again."

"No problem, we'll be in touch anytime."
