I Have a Research Support System

At around five o'clock in the afternoon, Caiyi 216, Xu Qiu and other four people sat around the desk, while Sun Wo tested the device in the inner laboratory.

Wu Feifei's phone screen suddenly lit up. She glanced at the phone, her expression changed slightly, and then she said to everyone: Teacher Wei has a message and asked us 'how'?

After a pause, she added: Everyone, report to me a summary of today's work in words. Xu Qiu, please ask those two from Zhang Jiang for me.

You don't need to ask, I know what the two of them are doing, Xu Qiu answered calmly, and said, Han Jiaying is synthesizing her 3D-PDI molecule, and at the same time testing whether the newly arrived microwave reactor works well, and Chen Wanqing is synthesizing her 3D-PDI molecule. The A-D-A molecules, CH1 and CH2, are today post-processed in the last step of the reaction.

Okay, I've made a note, Wu Feifei nodded and asked, What about you?

Xu Qiu tested the TEM in the morning, and tested the energy level structure with the CV method in the afternoon, so let's write it like this. Xu Qiu thought for a while.

Next, Wu Feifei counted the work of several other people, wrote a long paragraph of text, and sent it to Teacher Wei after confirming that there were no omissions.

Soon, the screen of her mobile phone lit up again. Xu Qiu rolled her eyes and saw Teacher Wei replied with an emoticon package [received]. It was two large three-dimensional characters that were rotating, and there was a red flower beside it embellishment.

By the way, is it morning with Teacher Wei? Xu Qiu asked casually.

Madou is about 7 hours faster than Sweden, so five o'clock in the afternoon here is almost... Chen Wanqing calculated for two seconds, Ten o'clock in the morning.

That's it. Xu Qiu nodded. He was good at science, but not so good at liberal arts. When he was in his first year of senior high school, he had an average score of 90 in science and 60 in liberal arts. Of course, he was also in the liberal arts class. The reason for writing science homework is related.

Everyone chatted for a while, Wu Feifei walked into the laboratory to discuss with Sun Wo, and could vaguely hear:

How efficient are these tin-based devices?

It's 1%, and I don't know how they achieved 6% in the literature. Obviously, the experimental steps are exactly the same.

Maybe there are some key steps hidden, and we can't completely refer to the literature, we have to find the conditions for optimization by ourselves.

Okay, next time I'll try the thermal spin coating method.

Tian Qing and Duan Yun started to pack their schoolbags, intending to leave early. Generally, after Teacher Wei has checked the post, there is a high probability that they will not look for them again, let alone Teacher Wei is abroad now.

Xu Qiu was not in a hurry to leave. He had to wait for Han Jiaying to come back from Zhangjiang. He had received news that they were on the school bus at five o'clock, but this time period happened to be the evening rush hour, so it was estimated that they would arrive at school at six o'clock.

He originally planned to start a new article today and sort out the context first.

As a result, as soon as I created a new WORD file and was ready to start working, I found a problem—there was no Nat. Common. contribution history in the group, that is to say, there was no corresponding template.

He had to manually make a template based on the commonly used Wiley template and compare it with the articles published by other researchers on NC.

While Xu Qiu was making the template, other people left one after another, and the last one to leave was Sun Wo.

It wasn't until the early six o'clock that Xu Qiu finished the template. At this time, he was the only one left in the office. He looked at the time and muttered, They should be here soon.

As soon as the words fell, Han Jiaying and Chen Wanqing appeared at the door of the office together, Brother, we are back~

The junior went to Xu Qiu and sat down. The senior took out a garbage bag from her schoolbag and walked to the inner laboratory.

Xu Qiu took advantage of the situation and grabbed the junior girl's little hand, and asked with concern: How does the microwave reactor work?

The effect is good, Han Jiaying said excitedly: Using a microwave reactor, under the same reaction conditions, the yield is close to 70% in 6 hours, and the yield of the previous control group was only 40% in 24 hours.

However... The junior girl pouted, and changed the topic: I don't have enough time today, and I haven't finished processing the product completely.

It's good that the microwave reactor is easy to use. You can save the product and process it slowly, Xu Qiu comforted at first, and then said: Next time, you can try the effect of microwave reactors for other reactions. In theory, most For synthetic reactions, microwave heating can be used to increase the reaction rate, especially those reactions that require 24 hours or even 48 hours, which can save a lot of time.

Yeah, Han Jiaying nodded in agreement, And I think some reactions with low yields can also be tried with microwave reactions. Maybe it can greatly increase the yield like this reaction.

This is also a good idea. Xu Qiu praised, it is a good thing that the school girl has learned to draw inferences from one example.

At this time, Chen Wanqing came out of the inner laboratory and said to Xu Qiu: Finally, CH1 and CH2 have been synthesized. This time there are about 50 mg of the product. I put it in my lock box in the glove box.

Xu Qiu understood the meaning of the senior sister's words in an instant, and responded, Okay, if I make devices on Sunday, I will send you a batch of devices.

Sister, shall we have dinner together? Han Jiaying suggested.

Chen Wanqing smiled and waved her hands, carrying her schoolbag, I won't bother you, let's go first.

...

After dinner, Xu Qiu sent Han Jiaying back and returned to the dormitory alone. When he entered the door and saw that his two roommates were not there, he turned off the light and lay down on the bed.

I wonder if there are any surprises? Xu Qiu muttered, and then entered the simulation laboratory II.

At this time, the simulation experimenters have stopped working, which means that six new solvent systems have been arranged in the morning, and the preliminary exploration work has been completed.

Xu Qiu checked the data saved in the system, and among the six new solvent systems, the chloroform/dichlorobenzene system stood out.

The dichlorobenzene here represents o-dichlorobenzene o-DCB, and it has two brothers, m-dichlorobenzene and p-dichlorobenzene, where the ortho-middle pair refers to the two chlorines on the benzene ring The relative positions of each are separated by 0, 1, and 2 carbon atoms, respectively.

Dichlorobenzene is also a common processing solvent used in the field of organic photovoltaics. However, due to its relatively high boiling point, it must be used with a high-concentration solution during spin coating, which is a waste of material. Xu Qiu only tried the traditional P3HT system at the beginning. , used dichlorobenzene as a processing solvent, and then mainly used chloroform and chlorobenzene.

In the final result, based on the chloroform/dichlorobenzene mixed solvent, the highest efficiencies of the two best systems by Xu Qiu and Xuemei were 8.02% and 7.15%, respectively.

Finally broke through 8%!

I didn't expect the use of dichlorobenzene as a solvent additive to be so effective.

Moreover, there is still hope for further improvement, after all, it was only a preliminary exploration before.

Excited, Xu Qiu quickly formulated a new set of experimental conditions based on the existing data and handed them over to the simulation experimenters for testing.

At the same time, he also arranged to explore the performance of the device with the CH1 and CH2 materials he just copied from his senior sister.

After the arrangements were made, he carefully looked at the data again, and found that not all solvent additives were helpful to improve the performance of the device.

For example, another system added with chloronaphthalene, the performance of the device decreased instead, not as good as the pure chloroform system without additives.

Finally, Xu Qiu looked at the data of the chloroform/dichlorobenzene system again, stared at the 8 for a long time, and then left the simulation laboratory satisfied.

A world record! Xu Qiu exclaimed excitedly.

What world record? In the darkness, a voice suddenly sounded faintly.

Xu Qiu was startled and shivered. When he came out, he saw that there were no lights around him. He thought there was no one there. After carefully recalling the voice just now, he probed, Tao Yan?

It's me, Tao Yan said weakly, I participated in a quarter-horse long-distance race in the afternoon, and went back to the laboratory to work until after six o'clock. I'm exhausted today.

Faculty, school, or club activities? Xu Qiu asked, and he instantly made up the picture in his brain. Tao Yan must have planned to rest for a while when he came back. Seeing him lying on the bed, he simply turned off the light.

Usually, sophomores and juniors participate in the activities organized by the Student Union of the Department of Materials Science and Technology. This time, if there are no people, I will be recruited. Tao Yan changed the subject, Don't talk about me, I just heard you say something about a world record.

Oh, Xu Qiu said calmly, Recently, I have made a small breakthrough in my work, breaking the world record in the field of PDI non-fullerene acceptors.

You call this a small breakthrough? You have broken the world record! Tao Yan exclaimed, and after a while he said, It's still you boy NB, you have published four or five articles in silence.

Almost, four articles have been published, and one more is on the way. Xu Qiu responded.

Amazing, I don't know when I will be able to publish an article, and it is hard to read the literature now. After a pause, Tao Yan suddenly said: By the way, you still remember the senior sister Zhao Anqi who graduated from our department last year.

I have a little impression, what's the matter? Xu Qiu asked curiously, he had heard about Zhao Anqi, after all, she was from the same school and department, and the other party just happened to be one year older than him.

When Zhao Anqi was about to graduate, she suddenly became popular on the Internet. She was probably a student from Shanghai University, Mensa member, one SCI work with 5 undergraduate articles, and finally graduated and went to Harvard University.

However, Xu Qiu thinks that she can get out of the circle mainly because of her appearance. If she looks crooked, it's useless to give her ten SCI articles.

After all, in the academic circle, there are quite a few who can publish SCI, but not many who can post SCI and are beautiful, and in terms of public opinion, girls have an advantage over boys.

Xu Qiu prides himself on the fact that he has a lot of articles, including the review on the road, and now he has five SCI articles, and the articles he published are not parallel imports. AM, AEM, and ACS Energy Letter are all very high-quality SCIs. But I haven't seen it reported anywhere.

Having said that, it is indeed rare for undergraduates to publish five articles and one for SCI.

I think you are quite a good match, why don't you make a CP with her? Tao Yan suggested, Maybe you will be a 'scientific research god' tomorrow.

Xu Qiu scolded with a smile: Fuck you, why don't you change your career as an entertainment reporter after graduation, and besides, I have a girl.

This time it was Tao Yan's turn to be surprised: Huh? I don't know when it happened.

A few days ago, the junior girl in our research group, Han Jiaying. Xu Qiu said, anyway, the group has made it public, so there is no need to hide it from the roommates, and besides, he and Tao Yan's laboratory is in Caiyi, sooner or later He will also find out.

It turned out to be her, Tao Yan suddenly said, When I first met you two, I thought there was something wrong with you, but I didn't expect Xu Qiu, with your thick eyebrows and big eyes, to eat weeds.

Hehe, Xu Qiu fought back not to be outdone, You still have the face to criticize me, how much have you caused trouble to our girls from the materials department?

You can't talk nonsense, Tao Yan said with an innocent tone, I'm looking for good friends from outside departments.

By the way, why have you stopped recently? Xu Qiu answered casually.

Wait for someone who is destined. Tao Yan pretended to be devout.

speak English.

Let's talk about it slowly after being promoted to a graduate student. It's not convenient to start during the graduation season.
