I Have a Research Support System

Not long after, Xu Qiu heard the sound of the door lock turning.

He looked up and saw that it was Han Jiaying.

It's just that her shape is a little bit unique.

He carried Xu Qiu's large schoolbag on his back, and a small black leather backpack hung in front of him.

Looking at her like this, is she planning to stay here and do experiments with him?

Xu Qiu took the schoolbag handed over by the junior girl, and tentatively said, "You are..."

"I'm here to help the senior brother with the experiment, so that the senior brother can concentrate on writing articles." Han Jiaying said.

"okay."

It was just a random thought just now, but I didn't expect it to come true.

Xu Qiu thought for a moment and asked:

"You just watched the operation once, have you learned it? Do you want me to teach you again?"

"To be honest, I'm not familiar with the experimental operation yet."

Han Jiaying picked up the operation manual next to the computer, shook it and said:

"However, there is an operation manual here, you can study it again, besides, isn't the senior brother here, if you have any questions, you can always ask you."

After speaking, she glanced at the computer screen and found that the first batch of samples had not been tested, so she began to read the operation manual carefully.

Xu Qiu murmured in his heart, does this school girl belong to Nougaty?

He went to Zhangjiang and followed Zhangjiang, and he went to Xiancai to follow Xiancai.

I can't guess what she really thinks.

Did he just come here to help him, or did he come to improve his favorability, or was he a third or fourth author who planned to make an article?

It can't be because of his appearance.

Xu Qiu thinks that his charismatic personality has not reached the point where his sister is obsessed with it.

After thinking for a long time, I still can't figure it out.

In this case, then no longer entangled, just accept it.

Anyway, if someone came to help, at least it would be no loss for him.

However, he was still a little worried about the experimental ability of the junior. If she was the second senior, a laboratory killer, the situation would be different.

After observing for a while, Xu Qiu found that Han Jiaying's self-study ability is not bad.

After reading the manual, she was able to change samples and test independently without asking him for help.

Seeing this, Xu Qiu felt relieved and concentrated on writing the article.

This is a treasure.

...

The surroundings have been very quiet, only the sound of instruments, the occasional footsteps outside the corridor, and the noise made by the school girl when changing samples.

After finishing a paragraph of the thesis, Xu Qiu raised his head and looked to the side.

I saw Han Jiaying wearing earphones, holding a book of "Semiconductor Physics" in her hand, and reading it seriously.

After thinking about it, he felt that it was better not to disturb each other, so he continued to write articles.

After an unknown amount of time, he suddenly felt something hard poke his shoulder.

After recovering, Xu Qiu found Han Jiaying sitting beside him, staring at him.

She probably poked me with something just now.

"Brother, I'm hungry, let's go have lunch." Han Jiaying said.

Xu Qiu glanced at the time on the bottom right corner of the computer.

Before I knew it, it was past twelve noon.

"Sorry, I forgot the time when I got busy, I kept you waiting for a long time."

"It didn't take long, I just changed the DSC sample."

"Let's go, please eat in the cafeteria."

Before leaving the laboratory, Xu Qiu looked at the computer screen of DSC.

Judging from the shape of the curve, it took about ten minutes to run.

...

There is a cafeteria next to the Xiancai building, and it is only two steps away. It is very convenient to eat.

Unlike the material first floor, there are three cafeterias "nearby".

However, the three canteens are almost exactly on a circle with the first floor of the material as the center.

This time is not the peak period for dining, and there are not many people in the cafeteria.

The two finished their meals and found a place to sit down.

"Just now I saw you were reading "Semiconductor Physics". I remember that you are as talented as I am, so you shouldn't need to take this course." Xu Qiu took the initiative.

"It doesn't need to be repaired, mainly because there are solar cells here," Han Jiaying said:

"But I don't even know the basic principles of the photoelectric effect and semiconductors, so I try to teach myself."

"Well, then you can read this book, and you can ask me any questions you encounter."

"Okay, thank you brother."

Xu Qiu thought that he had also experienced such a stage at the beginning, and his eyes were dimmed to the basic principles of organic photovoltaics.

He didn't read "Semiconductor Physics" systematically, but he read a lot of related literature, and gradually understood everything.

After all, the documents Mr. Wei showed them were not all about synthetic materials and device performance, but also a lot about theoretical research.

In fact, the content of "Semiconductor Physics" is more based on inorganic semiconductor materials, such as silicon, III/V compounds, copper indium gallium selenide and the like.

The theory in it cannot be fully applied to the field of organic photovoltaics, but it can still be used as a reference in the general direction.

This book is also a good choice for getting started, and I will show her the literature later.

...

After lunch, return to Xiancai 528.

The instrument is running normally, and the DSC curve of the current sample will be measured immediately.

Xu Qiu took a closer look and found that when he left, it was still a flat curve, but now there are ups and downs.

Moreover, the undulations are not small, which indicates that the crystallinity of this sample is very good.

Thinking of this, he hurriedly asked, "Which sample is this?"

"Sample No. 4."

Senior sister's samples are from No. 1 to No. 3, and from No. 4 onwards are his samples.

That being said, it was an unexpected discovery that our own material has high crystallinity.

If this is the case, will this discovery help to improve the performance of my device?

Xu Qiu fell into deep thought, while Han Jiaying stood beside her, not daring to breathe for fear of disturbing him.

Suddenly, Xu Qiu clenched his fists tightly.

I see……

ghost.

He felt that inspiration came into his mind, but it seemed to leak out from his fingers.

I stood still and thought for a long time, but still got nothing.

Xu Qiu shook his head.

Forget it, let's continue to code the paper.

After five o'clock in the afternoon, the test is completed, copy the data, turn off the instrument, clean up the garbage, lock the door, return the key, and return to Material 1.

...

"It's all over, what's the result?" Chen Wanqing asked.

"Senior sister, your three samples have no obvious DSC signals, but the DSC crystallization peak signals of my five samples are all very strong," Xu Qiu said:

"The crystallization performance of my sample should be good."

"High crystallinity, no wonder, that makes sense." Chen Wanqing said.

"Sister, what are you referring to?" Xu Qiu asked curiously.

"It's like this. When I tested the light absorption curve for you earlier, one of the curves shifted," Chen Wanqing said.

"If your polymer material is crystalline, then I guess I didn't heat the solution before applying it."

After listening to the senior sister's words, Xu Qiu settled in place and murmured:

"Temperature, crystallinity, blend morphology, I understand..."

The inspiration that slipped away, after a while, came back again.
