Xu Chuan was stunned for a moment, and he didn't understand why this came to him again.

He is now a physics student who has only achieved a little in mathematics, and he doesn't know anything about materials, so ask him what he does.

After thinking about it, he said, "I'm not familiar with the material, but from a mathematical point of view, I might be able to give a suggestion." ”

"Of course, it's just advice."

Chen Zhengping raised his eyebrows, glanced at his disciple, and said, "Just say it." ”

"I think that when the mathematical model is complete, the experimental process in all aspects has reached the optimal point, and in this case, if there are still defects, it may not be that there is a problem with the experimental process."

"It could be the raw material, or the reducing agent, or the catalyst, something might be wrong."

"I remember that you said a few days ago that hydrogen reducing agent is indeed the most suitable reducing agent for tungsten diselenide at present, but this data source is not so rigorous, and it may not be applicable to your new research and development method of tungsten diselenide."

Hearing this, Chen Zhengping pondered for a moment and said, "You mean to replace the hydrogen reducing agent?" ”

Xu Chuan nodded and said, "Well, it's not necessarily a problem with the reducing agent, maybe it's a hot solvent, but anyway, now that the mathematical model has been made, the experimental process has reached the optimum, and it doesn't take too long to experiment with a new reducing agent or hot solvent." ”

"And after you have a certain amount of data, you can use mathematical models to analyze and analyze the best results, so why not give it a try?"

"If the hydrogen reducing agent doesn't work, then what reducing agent should be replaced?"

Chen Zhengping thought about it, as if he was talking to himself, and as if he was asking Xu Chuan.

Hearing the inquiry, Xu Chuan was a little embarrassed, and said, "I don't know about this, so I won't bother you, teacher, I have to go back and prepare for the Princeton Math Conference in February." ”

He didn't lie, he really didn't know what kind of reducing agent was the most suitable for the synthesis of tungsten selenide nanosheets.

However, based on his past experience in material research and development, he can speculate that one or two reducing agents will be a little better than hydrogen reducing agents.

But he can't say it, after all, he doesn't have any experience in material research and development now, and a mentor who casually says that he guesses himself will not necessarily believe it.

Without evidence, no one will do this without any data support, after all, every experiment is to burn money.

And with Chen Zhengping's ability, he has already come to this point, and with the assistance of mathematical models, it is not too difficult to solve the impact caused by van der Waals.

At most, it's a matter of taking the time to try it out.

It may not be perfect, but it can certainly solve some problems.

In addition, the yield of 80% is of some value for tungsten diselenide.

Because the countries that have mastered the synthesis of tungsten diselenide are basically synthesized by CVD tube furnaces.

Although the yield rate will be higher, reaching more than 90 percent, the price of the top CVD tube furnace is not cheap, that thing is more than 100,000 units in China, and German, the casual one in small island countries is hundreds of thousands, and the more expensive one can even break through seven figures.

This new thermosolic synthesis does not require a top-of-the-line CVD tube furnace, and in this regard, it is enough to demonstrate its great advantages.

If the mentor finally solves the impact caused by van der Waals, the yield of tungsten selenide nanosheets can be increased to 90% without the need to be very high, and the market can be directly smashed through.

At that time, not to mention that the West monopolized tungsten diselenide materials and sold them to China at a high price, even if they fought a price war with China, there were no pants left that could be compensated.

.......

Hearing Xu Chuan's words, Chen Zhengping woke up, looked at Xu Chuan and sighed: "Well, this research and development experiment of tungsten diselenide materials is thanks to you." ”

"In fact, more than a month ago, when the hot solvent synthesis method had been stuck at 60% efficiency, I had a vague idea of giving up this project."

"Because the delay is too long, every experiment is burning money, but there is almost no progress."

"I didn't think about this before you suggested that the peaks affected the raw materials, and I had someone to analyze the data before, but I didn't get any useful information."

"So I had a vague feeling that this project might not work, so I was ready to give up after the Chinese New Year if there was no progress."

"But now, 80 percent of the yield is worth enough, and I'll try my best to try to improve it and solve the Van der Waals effect."

Smiling, Chen Zhengping continued: "No matter what, I really have to thank you this time, after the project is completed and submitted, your bonus will not be less, after all, this is a project related to the market value of billions of meters." ”

"In the future, if you have the opportunity, you can come with me to learn materials, and you can also be a side hustle."

By now, the haze in Chen Zhengping's heart has almost dissipated.

Don't look at him, as an academician, he has reached the top of the domestic scientific community, but the pressure will not be less than any professor, or even greater.

On the other side, Fan Pengyue, the senior brother who heard the words of the mentor, was shocked.

Mentor wants to cancel the project? He had never heard the teacher tell him about it.

If the project is canceled, he will most likely have to postpone it.

It's dangerous.

Fortunately, the little junior brother saved his life.

Gotta find a chance to thank you.

Do you want to soak your feet or do a big health care?

I just don't know which one the little junior brother likes?

.......

Coming out of the material research and development building, Xu Chuan looked up at the blue sky and stretched.

The mentor's material experiment is basically over here, and the rest has nothing to do with him, he can wait for the bonus after the project is completed and submitted.

As for the next thing, it is to prepare for the Chinese New Year to go to Princeton.

It's January 15, 2016 in the solar calendar, and there are two or three days left for the winter vacation, and the math club in Princeton starts on February 16, and this year's Chinese New Year is February 7.

In other words, he had to leave home on the eighth day of the lunar calendar at the latest.

"In the blink of an eye, a year has passed." Looking into the distance, Xu Chuan sighed.

But this past year, he has not wasted time.

IMO + IPO double gold medal, participate in the information war to solve the information security crisis for the country, two papers + solve a world-class mathematical conjecture, although the mathematical conjecture is only a weakened form, but it is also a world-class problem.

On top of that, he learns new math and helps his mentor solve a project that is about to be abandoned.

Thinking about it, life is still quite sufficient.

Of course, in addition, he has earned millions of dollars in academic papers and achievements in this year, not to mention, in terms of academic performance, this is not worth mentioning.
