Xu Chuan was stunned for a moment, wondering why this happened to him again.
He is now a physics student with only some achievements in mathematics, and he knows nothing about the material. Why do you ask him?
After thinking for a while, he said: "I'm not familiar with the material, but from a mathematical point of view, I may be able to give you a suggestion."
"Of course, it's just a suggestion."
Chen Zhengping raised his eyebrows, glanced at his disciple, and said, "Just say it."
"I think that when the mathematical model is complete, all aspects of the experimental process have reached the optimal point. In this case, if there are still defects, maybe there is no problem with the experimental process."
"There may be something wrong with the raw materials, the reducing agent, or the catalyst."
"I remember that the teacher said a few days ago that the hydrogen reducing agent is indeed the most suitable reducing agent for tungsten diselenide at present. However, the source of this data is not so rigorous and does not necessarily apply to your tungsten diselenide.
New research and development methods for tungsten.”
Hearing this, Chen Zhengping thought 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. It might be a hot solvent. But anyway, the mathematical model has been made and the experimental process has been optimized. Experimental one
It doesn’t take too long to get a new reducing agent or hot solvent.”
"And after we have certain data, we can use mathematical models to analyze and analyze the optimal results. Why not give it a try?"
"If the hydrogen reducing agent doesn't work, what kind of reducing agent should be replaced?"
Chen Zhengping thought deeply, as if talking to himself or asking Xu Chuan.
Hearing the inquiry, Xu Chuan felt a little ashamed 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 Mathematical Society in February."
He wasn't lying. He really didn't know what reducing agent was most suitable to use in the synthesis of tungsten diselenide nanosheets.
However, based on his past experience in material research and development, he can speculate on one or two reducing agents that are better than hydrogen reducing agents.
But it's impossible for him to say that, after all, he doesn't have any experience in material research and development, and even a mentor who says it's his own guess may not necessarily believe it.
It is unfounded and without any data support. No one will do this. After all, every experiment costs money.
Moreover, with Chen Zhengping's ability, he has already reached this step, and with the assistance of mathematical models, it is not too difficult to solve the impact caused by van der Waals forces.
The most you can do is spend some time trying more.
Maybe it can't be perfect, but it can definitely solve some of the problems.
In addition, with a yield of 80%, this synthesis method is already of certain value for materials such as tungsten diselenide.
Because countries that have mastered the synthesis of tungsten diselenide now basically use CVD tube furnaces for synthesis.
Although the yield rate will be higher, reaching more than 90%, the price of top-level CVD tube furnaces is not cheap. Domestic products cost more than 100,000 units, and those from Germany and small island countries can easily get one.
It can cost hundreds of thousands, and the more expensive ones can even exceed seven figures.
This new hot solvent method synthesis does not require a top-notch CVD tube furnace. At this point, it is enough to demonstrate its huge advantages.
If the instructor finally solves the impact of van der Waals forces and can improve the yield of tungsten diselenide nanosheets, it does not need to be raised to a very high level. It can be raised to 90%, and this market can be directly penetrated.
.
By then, let alone the Western monopoly on selling tungsten diselenide materials to the country at high prices, even if they start a price war with the country, they will lose their pants.
.......
Hearing Xu Chuan's words, Chen Zhengping woke up with a start, looked at Xu Chuan and sighed: "Well, this research and development experiment of tungsten diselenide material is thanks to you."
"Actually, for more than a month before, when the thermal solvent synthesis method had been stuck at 60% efficiency, I had a vague idea of giving up on this project."
"Because the delay is too long, every experiment is burning money, but there is almost no progress."
"Before you suggested that the peak segment affects the raw materials, I had not considered this issue. Regarding the data, I had asked someone to analyze it before, but I did not get any useful information."
"So I had a vague feeling that this project might not work, so I was ready to give up if there was no progress after the New Year."
"But now, the 80% yield is already valuable enough. I will try my best 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 with a market value of billions of meters."
project."
"If you have the opportunity in the future, you can come with me to learn materials, and you can also do it as a side job."
By now, the haze in Chen Zhengping's heart has almost dissipated.
Although he has reached the top of the domestic scientific community as an academician, the pressure is no less or even greater than that of any professor.
On the other side, Senior Brother Fan Pengyue was shocked when he heard his mentor's words.
The instructor wants to cancel the project? He has never heard the teacher reveal this.
If the project is cancelled, he will most likely have to delay its completion.
so close.
Fortunately, his junior brother saved his life.
I need to find a chance to thank you.
Should I take a foot bath or go for a general health care treatment?
I just don’t know which one my junior brother likes?
.......
After coming out of the materials research and development building, Xu Chuan looked up at the blue sky and stretched.
The instructor's material experiment is basically over here, and the rest has nothing to do with him. He will just wait for the bonus after the project is completed and submitted.
As for the next thing, that is preparing to go to Princeton after the New Year.
It is already January 15th, 2016 in the Gregorian calendar, and there will be winter vacation in two or three days. The Princeton Mathematical Society will start on February 16th, and this year the Chinese New Year is on February 7th.
In other words, he would have to leave home by the eighth day of the lunar calendar at the latest.
"In the blink of an eye, another year has passed." Xu Chuan sighed as he looked into the distance.
But he didn't waste time in the past year.
imo ipho double gold medal, participated in information warfare to solve the information security crisis for the country, two papers solved a world-class mathematical conjecture, although the mathematical conjecture is only in a weakened form, it is still a world-class problem.
In addition, he also learned new mathematical knowledge and helped his tutor solve a project that was about to be abandoned.
Thinking about it, my life has been quite fulfilling.
Of course, in addition to this, he earned several millions from academic papers and achievements in this year, not to mention it. In terms of academic achievements, this is not worth mentioning.
