I Have a Research Support System

Wei Xingsi's face immediately flushed red, and the previous exhaustion seemed to be swept away.

He sat in front of the computer and said loudly: Have you got the USB drive, show me the article!

Xu Qiu handed over the USB flash drive, walked behind Teacher Wei, pulled a chair and sat down.

Afterwards, the two started discussing the text on the computer screen.

First of all, a new type of 3D-PDI molecule was developed, involving three molecular structure optimization methods: three-dimensional, fused ring, and introduction of selenium atoms...

Secondly, using DFT simulations, analyze the impact of these three-step optimizations on the molecular structure, and how this impact affects the light absorption properties of the acceptor molecule, the blending morphology with the donor material, and the photoelectric performance of the device...

Again, through TRPL, and the TAS test that has not yet been carried out, the impact of the changes in the molecular structure of the three generations of 3D-PDI on the charge transport kinetics of organic photovoltaic devices...

In the end, an efficiency as high as 8.4% was obtained, breaking the current highest photoelectric conversion efficiency of the PDI system and even the entire non-fullerene system...

It was a discussion, but Xu Qiu was talking and Wei Xingsi was listening.

It took a total of more than ten minutes, and Xu Qiu roughly explained the main writing ideas and highlights of his work.

Overall, the writing is good, and NC has a good chance. Wei Xingsi rested his chin on one hand, nodded slightly, let out a breath, and said in a low voice, Okay, let's do this today, and we'll talk about it on Sunday.

Okay. Xu Qiu agreed, and he could see that after the discussion, Teacher Wei's condition was not good enough.

It's like after taking medicine, you can maintain a moment of bravery, but after the climax, you become more decadent.

Although it is not so appropriate to use this metaphor to describe the current Teacher Wei, it generally means that.

Wei Xingsi waved his hand and said, By the way, I brought you the two boxes of chocolates on the coffee table. Take them and share them.

Okay, Xu Qiu walked to the coffee table and asked casually, Do you need to call other people over?

As soon as he finished asking, he regretted a little, isn't this a scam...

Fortunately, Wei Xingsi wasn't that interested either: I'm going home, the other Sunday groups will talk about it later.

Xu Qiu nodded, heaving a sigh of relief, and then took a general look at the gift boxes in front of him. It felt like they were bought directly from the duty-free shop at the airport.

The one with the chocolates was quite obvious, so Xu Qiu picked it out from the inside, picked it up and left without being polite.

As for the other few gift boxes, I can't tell what they are from the outer packaging, but he guessed that they might be gifts for the principal and deputy deans of the department. Teacher Wei brought them special products when he came back from several business trips. It's tea, ornaments or something.

Back at 216, as soon as Xu Qiu put the gift box on the table, Wu Feifei immediately came over and asked, From Teacher Wei? What have you been talking about for so long?

Xu Qiu gave a hmm and then said: At first he talked about his experiences abroad, and then he talked about NC articles, which wasted a lot of time.

That's right, Wu Feifei nodded, For him, posting an NC is more important than posting an AM, EES and other top-level materials. After all, it starts with N, and the meaning is different.

While speaking, Wu Feifei had already unpacked the gift box, took out a chocolate candy from it, peeled off the outer candy wrapper, put it in her mouth, and chewed, The taste is not bad, not very bitter, and there is a filling inside, you one comes?

Xu Qiu casually took the two candies from Wu Feifei, returned to his seat, and continued to work. Just now, Teacher Wei made a few comments, and he just changed them while the comments were hot. forgot.

After a while, Xu Qiu heard the sound of the door slamming in the direction of room 218 next door. In this old school building, the door locks are more or less problematic, and they cannot be closed without force.

Teacher Wei should have left directly through the back door. Wu Feifei said suddenly.

Xu Qiu waited for more than ten seconds, but did not see Teacher Wei appearing at the door of 216, so he asked curiously, How did you know?

Hearing the footsteps, it's obvious that he went downstairs from the other side. Wu Feifei explained.

Okay. Xu Qiu didn't hear footsteps at all just now. In fact, if Teacher Wei didn't deliberately make a da da da sound, it would be difficult for most people in the laboratory to notice him in advance.

But Wu Feifei is an exception. She is like a human-shaped radar, and can detect Wei Xingsi's whereabouts from a long distance. Therefore, when she is paddling, she is almost never caught by Teacher Wei. Of course, this is also related to her paddling. Relatively low frequency.

Speaking of the back door on the first floor of the material, it is an emergency escape passage with a six-digit combination lock. No one knew the combination before, and it has always been closed.

Later, a student in room 319 of Caiyi came to the department to ask for the password. The reason was if you don't know the password, how can you evacuate in case of an emergency? The department seemed to think that what he said made sense, and then gave He approved a note asking him to go to the security office in charge of the school's access control.

In the end, he successfully obtained the password of the back door, and pasted the note with the six-digit password next to the combination lock. Although he could only exit but not enter, it was also much more convenient.

...

On Sunday, after nearly two weeks, seven members of the research team gathered in 218 again.

At this time, Wei Xingsi had recovered his usual energy. He sat at the desk, glanced at the seven people sitting in a row with piercing eyes, and said, Let's start the meeting.

As usual, Feifei Wu made the first report. She said a few words, saying that she had been writing a review of Research Progress in Perovskite Thin Films and Single Crystal Preparation Methods last week, and she is currently finishing it.

Xu Qiu was a little surprised. He remembered that Wu Feifei seemed to have just started writing this review last Monday. Now it's only two weeks, and it's basically done?

You know, his previous review was a joint effort by three people, and it took a month to complete.

But after he thought about it, it was normal for her to be able to write so fast.

On the one hand, it’s because Wu Feifei didn’t do other work during this period, and she just used it to write articles, while Xu Qiu and the others probably only spent an hour on the review every day on average. Not the same.

Xu Qiu's article is a large review of the entire subdivision of non-fullerene acceptors, and hers is a small review that only focuses on the preparation methods of perovskite materials.

Therefore, the length of her review is not long, and she does not need to be as comprehensive as Xu Qiu, citing all perovskite-related articles, only needing to cite classic literature involving various preparation methods.

Speaking of it, it is relatively easy to write a review in emerging hot fields such as perovskite photovoltaics. As long as you grasp the hot spots and write a small review, not only is it effortless, but you can also publish a good journal.

Unlike Xu Qiu's current field of non-fullerene acceptors, which belongs to the unpopular subdivision of the less popular field of organic photovoltaics, if you want to write a review, you can only write a large review. If you write a small review, others may not understand it. I will buy it and send your article to the third and fourth districts.

Duan Yun's work on silver nanowire-doped PVDF substrate thermoelectric devices was basically completed two weeks ago, but the article has not been moved.

Now, after spending two weeks and making up a few experiments, I finally got the initial framework of the article out.

Although Xu Qiu looked at these experiments that Duan Yun rushed out on Thursday and Friday, at least the results were good, and Teacher Wei's ideological education work before leaving was not in vain.

Tian Qing also brought good news.

The in-depth research on the perovskite charge transport mechanism that she cooperated with Wu Feifei has obtained the core experimental data and conclusions, and listed five pages of PPT, mainly related to under different perovskite systems, charge transport The trap state during the process, the ratio change of deep traps to shallow traps, and the impact of this change on the optoelectronic performance of the device.

In fact, Wu Feifei didn't help much in this job. She mainly provided relevant perovskite research systems, and then Tian Qing made devices or samples for various tests and analysis.

Tian Qing intends to vote for JPCL, which is a journal in the field of physical chemistry. In fact, it can be seen from the abbreviation, J stands for journal, P stands for physics, C stands for chemistry, and L stands for letter.

At present, the JPCL impact factor is around 8, which is a journal in the first category and the second category. It is hard to say in the future. If the impact factor can break through 10, then it may be able to stabilize in the first zone. If the impact factor falls to 6 or 7, it may slip. For a thorough second district journal.

Xu Qiu did not expect Tian Qing to come up with so much data at the group meeting, because during the period when Teacher Wei was away, he often had to wait until the afternoon to see Tian Qing's people. After all, Teacher Wei was far away abroad, even if Checking the post can only be done in the afternoon, so it is very safe in the morning.

Xu Qiu reckoned that she should have kept a few hands on Mr. Wei...

After three waves of good news, Wei Xingsi laughed so hard that he couldn't close his legs. He sat down on the back of the chair triumphantly, and crossed his legs where Xu Qiu and the others couldn't see.

Then, Sun Wo came out and began to report.

He has been making devices for the past two weeks. Based on the tin-based perovskite battery, he has evaporated a total of eight batches of devices. He is already very familiar with the entire set of cleaning substrates, spin coating, evaporation, and testing processes.

The final test results are condensed on one page of PPT.

The good news is that the device is finally working, and it is no longer as efficient as before.

The not-so-good news is that the efficiency is a bit low, the highest is only 1%, while the literature value is 6%, and the target given by Mr. Wei is 5%.

After Sun Wo finished speaking, he turned his body sideways and stopped talking. Wei Xingsi stared at the image projected by the projector and tapped lightly on the table.

He looked at Sun Wo, then at Han Jiaying, and finally his eyes stayed on Xu Qiu for a while, before he said lightly:

Let's put the device away. Wu Feifei, after you finish writing the review, take him through all the characterizations that need to be done. Most of the testing laboratories can do it. The outside ones are mainly XRD and SEM. Finish the graduation project first. .”

With Xu Qiu and Han Jiaying in front, Wei Xingsi almost forgot that Sun Wo is what undergraduates should be like.
