I Have a Research Support System

Because today is most likely to be the last class meeting during the undergraduate period, the counselor Yu Qiang has a strong desire to talk.

He started at 5:30 and talked for almost half an hour, and he still didn't finish the first thing.

'Looking at him like this, this class will have to last two hours at least. ’ Xu Qiu shook his head, thinking to himself.

‘Fortunately, I had the foresight to leave a little earlier, finish dinner in advance, and bring my computer with me, so I’ll take the time to write a review. '

Tao Yan was sitting next to Xu Qiu, his eyes glazed over, seeing him take out his computer, open a Word document, and casually asked, "Are you writing an article again?"

Xu Qiu hummed, "It's a review, and I wrote it together with the two seniors who are organic in the group."

Tao Yan glanced at the computer screen a few times, then turned his gaze back, propped his head up on the table with his hands, and said weakly: "When will the class meeting end? Yu Qiang doesn't talk about the main points, just talk nonsense."

Seeing his state, Xu Qiu guessed something, "Didn't you have dinner?"

"That's right," Tao Yan complained as if he had opened up the conversation box, "I paddled the whole afternoon this afternoon, but before I got off work, my boss ran over and arranged a job for me, and I hurriedly finished the work. It's almost 5:30, there is no time to eat, hey, if Yu Qiang has ten minutes to go, and the first thing has not been finished, I will run away."

ten minutes later.

"I slipped away."

"Well, if there's anything important, I'll let you know on WeChat."

The seats of the two of them were closer to the back, and Tao Yan quietly left through the back door while Yu Qiang turned his head.

Tao Yan's departure did not cause any disturbance, and the class meeting continued as usual.

In the end, the whole class meeting lasted for two and a half hours before it finally ended.

It's really nothing important. Yu Qiang has notified some important matters in the email before.

Today is not so much a class meeting, but some life advice from the counselors. Compared with the counselors who are graduate students, this kind of college teacher in his forties has richer life experience and wider knowledge.

For students who are about to leave the ivory tower, it is still a little bit useful.

...

Xu Qiu packed up the computer and went back to Caiyi 216 again.

The device that I asked my sister to prepare before has been completed, and she is currently testing it.

However, judging by her expression, it seems that things are not going well.

Sure enough, as soon as he put down his schoolbag, he heard his senior sister complain, "Hey, my batch of devices is still not good."

"How efficient is it?" Xu Qiu walked into the laboratory quickly after hearing the words. He was more concerned about his own data, whether it reached about 4%.

"My C1 system currently has a maximum efficiency of 0.91%. I tested a piece of your system for you, and the efficiency is 3.58%." %, I will not measure the rest."

"Well, senior sister, have you thought about how to optimize it?" Xu Qiu asked. The result of this experiment is considered normal, at least it shows that senior sister's batch of devices is not a problem, but the upper limit of the material is there.

"I've thought about it," Chen Wanqing nodded, "I plan to make C2, C3, and C4 based on the structure of C1 in the future, but now C1 has only started less than 1%, so I'm a little bit uncertain."

"Hmm..." Xu Qiu pondered and began to think.

There is a high probability that he will also do the A-D-A system in the future. Now helping the senior is helping himself, but he focused on the PDI system before. Now that the senior is a new system, he has to go through the relevant literature again.

Forget it, the greater the ability, the greater the responsibility. Thinking of this, Xu Qiu said, "I have time to help you analyze and see if there are any good ways to improve."

"Really, that's great." Chen Wanqing smiled, recalling the few articles she had published before, which more or less had the shadow of Xu Qiu, and she immediately felt relieved when she heard what her junior said.

Immediately, she tilted her head, "By the way, my part of the review has been finished."

"So fast..." Xu Qiu paused, "That's right, senior sister, you pass the pillars less frequently, so we can discuss it later." In fact, the progress between him and Han Jiaying didn't drop much, almost 80% of the time was completed. about.

"Okay." Chen Wanqing nodded and continued the test.

After that, the senior sister tested three C1 devices continuously, and the efficiency fluctuated between 0.6% and 0.9%, so she gave up the glove box.

Xu Qiu connected seamlessly, spent some time, and finished testing his remaining five devices. The efficiency fluctuated between 3.4% and 4.1%.

This result fluctuates a bit more than the results obtained in Simulation Lab II.

The reason is that Xu Qiu did not conduct repeated experiments for this kind of exploratory experiment. There is only one device for each condition, so the fluctuation will naturally be great.

Back at the desk, Chen Wanqing learned of the results of Xu Qiu's device, and casually mentioned: "4% efficiency, 3D-PDI system, should be able to be published in the second district, I remember the last JACS review It's only 4%."

"Try to improve and improve, it's too wasteful to send directly to the second district now."

"That's right, your foundation is so high, you can go higher."

After chatting for a while, Chen Wanqing opened the word document of the summary, and the two sat together and started discussing.

The senior sister's overall writing ideas did not deviate, so Xu Qiu directly copied her part to his computer for use, and then polished the whole after the part he and the junior were responsible for was completed.

Previously, the three of them had divided the work on the second part of the review. Now that the senior had finished her part ahead of schedule, Xu Qiu asked her to write the third part first.

The third part also has three sub-themes, namely "light absorption performance", "charge transport" and "film microstructure". Qiu is in charge of "light absorption performance", and senior sister is in charge of the latter two.

Now that there is one more person, each person can just be responsible for a theme.

Xu Qiu connected with Han Jiaying who was still in Zhangjiang, and the three discussed it.

In the end, it was decided that he was still in charge of "light absorption performance", the senior was in charge of "charge transport", and the junior was in charge of "microscopic morphology of thin film".

...

After the discussion, Xu Qiu went to Teacher Wei's office to report the results.

I still remember that when he first came to the research group, he was quite cautious when he went to Office 218.

Half a year has passed in a flash, and looking for Teacher Wei now is like visiting.

Seeing that it was Xu Qiu, Wei Xingsi put on a smiling face, "How is it?"

Xu Qiu took two steps forward and came to Teacher Wei's desk. The two faced each other, "3D-PDI devices have a maximum efficiency of 4.1%."

"That's right, find a way to make it higher," Wei Xingsi nodded, "I used the sample from the company in Shencheng, right? Have you contacted them to buy the materials?"

"I bought 200 mg of P3TEA, and it should arrive within this week." Xu Qiu thought for a while, but didn't mention the price, it's still a bit expensive after all.

"Okay, do you have any experimental plans in the future?" Wei Xingsi asked casually.

"The main idea is to further optimize the molecular structure of 3D-PDI," Xu Qiu thought for a while and said, "The methods I think of temporarily include fused ring formation, N-position modification, N-position side chain engineering, and the introduction of heteroatoms."

"Okay, let's do it according to your idea first." Wei Xingsi didn't ask about the specific experimental steps, and suddenly said earnestly: "But don't always do experiments with tension, you must know how to combine work and rest, such as the gap between experiments, You can also write a review to relax, how is the review writing now?"

‘How do you feel that the combination of work and rest we understand is a little different? ’ Xu Qiu complained inwardly, and coped with it, "Now I'm writing the second part of the review, and it's almost 80% complete."

"As long as there is progress," Wei Xingsi nodded, then remembered something, "By the way, are you in Handan tomorrow?"

"Is there anything going on tomorrow?" Xu Qiuming asked knowingly. His plan for tomorrow is to do some basic characterization of 3D-PDI molecules in Handan, such as light absorption, energy level tests, etc. But looking at this, Mr. Wei probably If you want to arrange a job for him, it's better to ask clearly first, if it doesn't work, you can go to Zhangjiang for refuge.

"That's how it is," Wei Xingsi tapped on the table with two fingers, and said, "Qiu Heming from TRPL is coming to install the equipment for us recently. We initially planned to come tomorrow and Wednesday. If you are not free tomorrow, I will Make another appointment with him."

"I originally planned to go to Zhangjiang to do synthesis tomorrow, so I will do some basic characterization of 3D-PDI in Handan tomorrow." Xu Qiu said nonsense, and the various experiences after joining the group also made him tactful. Quite a few, TRPL is the instrument he is in charge of, and there is no way to hide from it, so it is better to get rid of it as soon as possible.

"Okay, then I'll send him a message to confirm this matter." After Wei Xingsi finished speaking, he edited a message to Qiu Heming, then returned and took out a can of Helaoji herbal tea from the refrigerator, and handed it to Xu Qiu.

...

Returning to 216, Xu Qiu prepared a few solutions, read a little about TRPL-related documents, and finished handling other matters in the laboratory, and sent a message to Han Jiaying to confirm when she would return by school bus.

Then, he waited ahead of time at the school bus stop, but he didn't tell her.

A few minutes later, the school bus full of students slowly drove into the main gate of the school, made a big circle, and then stopped slowly.

Han Jiaying got off the school bus slowly, with two white earphone cables still plugged into her ears.

Just as she was about to move towards the school gate, she suddenly saw a familiar figure under the street lamp, so she rubbed her eyes uncertainly, and realized that she had read correctly, and rushed over in surprise, "Why are you here?"

Xu Qiu hurriedly hugged her, "Are you surprised, are you surprised?"

"Hmm..." Han Jiaying was stunned for a moment, 'It's time to say "I miss you" so it's appropriate... Well, it's not important. '

The two hugged each other for a long time, feeling each other's warmth, and then they held hands and pressed the road while chatting, and then lingered downstairs in the dormitory for a while before parting reluctantly.
