Great Country Academician

From noon to evening, from sunset to bright lights, in the dormitory, Xu Chuan stretched himself.

After eight or nine hours of busy work, he finally finished sorting out the experimental data in his hands.

Glancing at the programming modeling software such as MATLAB, Lingo, Cplex, and python being downloaded on the computer, seeing the 68.3Kb/s and 72.1Kb/s traffic jumping on it and less than ten percent of the progress, Xu Chuan I just feel like a pain in the ass.

Can this campus network be broken a little more?

It's been almost ten hours, and the progress has only gone so far.

Looking at the time in the lower right corner, it was past nine o'clock in the evening. After rubbing his stomach, he got up to eat.

Another day of irregular work and rest, if this continues, he will get stomach problems sooner or later, and then eat soft rice.

Shaking his head, Xu Chuan went straight to the No. 2 canteen of Nanda University. At this point, the No. 2 canteen is still open.

After ordering two dishes at random, Xu Chuan sat in the corner and started eating. Suddenly, a figure came into his eyes.

The part-time girl I met at the last meal, will really come out from the back door of the cafeteria, holding a rag and a bucket of water in her hand

At first Xu Chuan didn't pay attention to it, but after taking two mouthfuls of food, he felt that something was wrong.

He raised his head suddenly, stared at the girl who was cleaning the dining table, and a sense of familiarity welled up in his heart.

"Isn't this Professor Zhou Hai's student, the senior who gave him medicine?"

Xu Chuan was stunned for a moment and reflected. No wonder the senior sister always felt a little familiar when delivering medicine to him before. It turned out that she was here part-time.

"Hi, senior."

Xu Chuan said hello.

On the opposite side, Liu Jiaxin, who was cleaning the table, couldn't help shaking when she heard the voice. She had been working part-time here for a year, and this was the second time someone greeted her.

The first time was her teacher Professor Zhou Hai.

Carefully raising her head, she searched for the source of the voice, and a bright smiling face came into her eyes.

Seeing that it was a familiar person, Liu Jiaxin was slightly relieved.

"Yes, it's you."

After saying hello in a low voice, her face turned red, and she was a little embarrassed to be bumped into by a familiar person to work here as a part-time job.

"Do you have to work part-time here every night? Sister." Xu Chuan asked casually after taking a bite of the food.

He didn't think so much, it's just a part-time job, and it's not like he hasn't done it before.

In his previous life, his family was far less wealthy than in this life. His parents were farmers, and they had to provide for a son and a daughter to go to school, and they both went to prestigious schools in the provincial capital. It only got better after a big bonus.

In the past, in order to subsidize his life, he also worked part-time when he was in college, distributing leaflets, tutoring and so on.

Liu Jiaxin nodded, and continued to lower her head to wipe the dining table and arrange the tables and chairs.

Xu Chuan didn't care either. After he finished eating, the second canteen was almost closed.

The next day, Xu Chuan took the data calculated yesterday afternoon to find his mentor Chen Zhengping who was in the material research and development building.

"You mean that the concentration of the hydrogen reducing agent has no effect on the synthesis and collapse of tungsten diselenide nanosheets?"

Chen Zhengping asked again in astonishment, took the manuscript paper half-believingly, and flipped through it.

Xu Chuan nodded and said: "From the data calculation point of view, it does not have much impact. I calculated the data of three samples yesterday, and the deviation of the synthesis and collapse of tungsten diselenide nanosheets is 0.03%. To about 0.05%, this deviation can be said to be very small."

On the other side, Fan Pengyue from Master Xiong who came over to listen quickly retorted: "How is this possible? The concentration of the reducing agent cannot have no effect on the synthesis and collapse of tungsten diselenide nanosheets."

"After dissolving sodium borohydride in an organic solvent, sequentially adding selenium powder and sodium tungstate to prepare a mixed solution, and then using a hydrogen reducing agent can effectively increase the production rate of tungsten diselenide."

"If there is no effect or even a small effect, what is it called a reducing agent, and we don't need to add a hydrogen reducing agent."

Xu Chuan shrugged, and didn't mind Fan Pengyue's rebuttal. He knew that Master Xiong had always had such a straightforward personality.

"But the result I calculated is like this. Maybe this violates common sense, but mathematics can't lie."

"That may be a problem with your calculations."

"No, there is nothing wrong with Xu Chuan's calculated data. The problem may really be in the hydrogen reducing agent."

On the side, Chen Zhengping suddenly interrupted Fan Pengyue, and continued: "Maybe the concentration of the hydrogen reducing agent is too high? Then it is saturated in the hot solvent, which will also cause no matter how we change the concentration of the hydrogen reducing agent, it will not be effective. Increase the production rate of tungsten diselenide."

Fan Pengyue frowned, and said: "But the concentration of the hydrogen reducing agent was obtained through our previous experiment. There can be no problem with it. If there is a problem, we should have discovered it in the previous experiment."

"And in the past, other laboratories, including the United States, Germany and other countries, have published hydrogen reduction papers on tungsten diselenide, and according to experimental data, hydrogen reducing agents are the most suitable for the generation of tungsten diselenide."

Hearing this, Chen Zhengping smiled and said: "Perhaps it is these things and our experience that have harmed us. We only experimentally confirmed the effect of the hydrogen reducing agent on selenium powder and sodium tungstate, but did not completely affect the entire Experimental procedures for new tests."

"And this time we used a new method and method to synthesize tungsten diselenide nanosheets by the hot solvent method. The previous experience and data may not be applicable, so problems may occur."

"Xu Chuan, what do you think?"

Changing the subject, Chen Zhengping suddenly asked Xu Chuan.

Caught off guard, Xu Chuan almost uttered his previous experimental theory, but he held back halfway.

Slowing down his thoughts, he said, "I'm not sure about this, after all, I'm not familiar with the material."

"However, I think it may be possible to establish a mathematical model to simulate the effects of temperature, pressure, reducing agent concentration, time and other parameters on the collapse and rolling of tungsten diselenide nanosheets?"

"You can still model? Have you learned?"

Hearing this, Chen Zhengping looked at Xu Chuan in surprise.

Just as Xu Chuan was about to nod, he thought of something, shook his head and said, "I'm not very familiar with this, but I can recommend someone."

"Who?" Chen Zhengping asked.
