Chapter 255: She should have left a few hands with Teacher Wei

Wei Xingsi's face was immediately red, and the exhaustion before it seemed to be wiped out.
　　 He sat in front of the computer and said loudly, "Is the USB flash drive brought, show me the article!"
　　 Xu Qiu passed the USB flash drive, walked behind Teacher Wei, pulled a chair and sat down.
　　 After that, the two began to discuss 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-dimensionalization, fusion, and introduction of selenium atoms..."
　　 "Secondly, using DFT simulation methods, analyze the impact of these three-step optimization on the molecular structure, and how this effect affects the light absorption performance of the acceptor molecule, the blend 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, analyze the changes in the molecular structure of the third-generation 3D-PDI and the impact on the charge transport dynamics of organic photovoltaic devices..."
　　 "Finally, an efficiency of up to 8.4% was obtained, breaking the current highest photoelectric conversion efficiency of the PDI system, and even the entire non-fullerene system..."
　　 said it was a discussion, mainly Xu Qiu was talking and Wei Xingsi was listening.
　　 It took a total of more than ten minutes, and Xu Qiu gave out the main writing ideas and the highlights of the work in general.
　　 "Generally speaking, the writing is good, NC has a good chance." Wei Xingsi put his cheek in one hand, nodded lightly, exhaled, and whispered: "Okay, let's do this today, and wait until Sunday."
　　 "Okay." Xu Qiuying made a peace. He could see that after the discussion, Mr. Wei's state was no longer good.
　　 is like being able to maintain a temporary bravery after taking a medicine, but after the orgasm, it becomes more decadent.
　　 Although using this metaphor to describe the current teacher Wei is not so appropriate, it is basically the same.
　　 Wei Xingsi waved his hand and said, "By the way, I brought you the two boxes of chocolates on the coffee table. Let's share them with you."
　　 "Okay," Xu Qiu walked to the coffee table and asked casually, "Do I need to call someone else over?"
　　As soon as he finished asking, he regretted it a little. Isn’t this a cheating...
　　 Fortunately, Wei Xingsi didn't have that interest: "I'm going home. The other Sunday teams will talk about it."
　　 Xu Qiu nodded, heaved a sigh of relief, and then took a look at the gift boxes in front of him. It felt like he had bought them directly from an airport duty-free shop.
　　The one with the chocolate is quite obvious. Xu Qiu picked it out from the inside. He was not welcome, picking it up and leaving.
As for the other gift boxes, I couldn’t tell what they were from the outer packaging, but he guessed that they might be gifts for the dean and deputy dean of the department. Mr. Wei brought them special products after several business trips before. It's tea, ornaments and so on.
　　 Back to 216, Xu Qiu put the gift box on the table, and Wu Feifei immediately leaned in and asked, "Ms. Wei sent it? What have you talked about for so long?"
　　 Xu Qiu let out a "hmm", and then said: "At first he talked about his experiences abroad, and then talked about NC articles, which took a lot of time."
　　 "Yes," Wu Feifei nodded, "For him, posting an NC is more important than posting a top magazine like this. After all, it starts with N, and the meaning is different."
While talking, Feifei Wu had already unpacked the gift box, took out a chocolate candy, peeled off the candy wrapper on the outside, put it in her mouth, chewed it, "The taste is not bad, it is not very bitter, there is still filling inside, you one comes?"
Xu Qiu took the two candies handed over by Feifei Wu, returned to her seat, and continued to work. Mr. Wei just made a few comments, which happened to be changed while the comments were hot. Otherwise, it will take a long time. Forgotten.
　　 After a while, Xu Qiu heard the sound of closing doors in room 218 next door. This kind of old school building has some problems with the door locks, and it can't be closed without force.
　　 "Ms. Wei should have left directly from the back door." Wu Feifei said suddenly.
　　 Xu Qiu waited for more than ten seconds, but did not see Teacher Wei showing up at door 216, so he curiously said: "How did you know?"
　　 "Listen to the footsteps, it is obvious that he has come down from the other side." Wu Feifei explained.
　　 "Okay." Xu Qiu just didn't hear the footsteps at all. In fact, if Teacher Wei did not deliberately make a "da da da" sound, it would be difficult for most people in the laboratory to notice him in advance.
But Feifei Wu is an exception. She is like a humanoid radar. She can detect Wei Xingsi's whereabouts from a long distance. Therefore, she was almost never caught by Teacher Wei when she was paddling. Of course, this was also the same as her paddling. Relatively low frequency.
　　 Speaking of the back door on the first floor of the material, it was an emergency evacuation passage with a six-digit code lock. No one knew the code before, and it was always closed.
Later, a student in Room 319 of Caiyi went to the department to ask for the password. The reason was
I don’t know the password. If there is an emergency, how can you evacuate urgently?
The department seemed to think that what he said was reasonable, and then gave He approved a note and asked him to go to the security office in charge of the school's entrance guard.
　　 In the end, he successfully got the password for the back door, and pasted the note with the six-digit password on the side of the password lock. Although he could only go out and not enter, it was a lot more convenient.

　　On Sunday, nearly two weeks later, the seven members of the research group gathered again at 218.
　　At this time, Wei Xingsi had recovered his usual spirit. He sat at his desk, glanced at the seven people sitting in rows, and said, "Let's start the meeting."
　　 As usual, Wu Feifei’s first report, she said briefly, saying that she had been writing a review of "Research Progress in Perovskite Thin Films and Single Crystal Preparation Methods" last week, and it is now being finalized.
　　 Xu Qiu was a little surprised. He remembered that Wu Feifei seemed to have just started writing this review last Monday, but now it's basically done in just two weeks?
　　 You know, his previous review was a joint effort by three people, and it took a month to complete.
　　 But he changed his mind, she can write so fast, it's normal.
On the one hand, it was because Feifei Wu did not do other work during this time, and only used it to write articles. At that time, Xu Qiu and the others might only spend an hour on reviews every day. On the other hand, it was also due to the type of reviews written by Feifei Wu and their Not the same.
　　 Xu Qiu’s article is a general review of the entire subdivision of non-fullerene receptors. She is a small review focusing only on the preparation methods of perovskite materials.
　　 Therefore, the length of her review is not long, nor does it need to be as comprehensive as Xu Qiu. All perovskite-related articles are quoted once, and only classic literature involving various preparation methods is required.
　　 Speaking of which, it is relatively easy to write reviews for emerging hot fields such as perovskite photovoltaics. As long as you catch the hot spots and write small reviews, it is not only effortless, but also good journals.
Unlike Xu Qiu’s current field of non-fullerene receptors, which is an unpopular sub-field in the less popular field of organic photovoltaics, you can only write a large review if you want to write a small review. Others may not Will buy it and call your article to the third and fourth districts.
　　Duan Yun Two weeks ago, the work on "Silver Nanowire Doped PVDF Substrate Thermoelectric Device" was basically completed, but the article has been silent.
　　 Now I have spent two weeks, made up a few experiments, and finally got the preliminary framework of the article.
　　 Although these experiments, Xu Qiu's eyes were all made by Duan Yun on Thursday and Friday, but anyway, at least the results were good, and the ideological education work of Teacher Wei before leaving was not wasted.
　　 Haru Tian also brought good news.
She and Feifei Wu collaborated on in-depth research work on the "perovskite charge transport mechanism". The core experimental data and conclusions have been obtained. Five pages of PPT are listed, mainly related to "charge transport under different perovskite systems. The trap state during the transport process, the change in the ratio of deep traps to shallow traps, and the impact of this change on the photoelectric performance of the device."
　　 In fact, Wu Feifei did not help much in this work. She mainly provided relevant perovskite research systems, and Tian Qing made devices or samples for various tests and analyses.
　　 Haru Tian intends to vote for JPCL, which is a journal in the field of physical chemistry. In fact, it can be seen from the abbreviations. J stands for journal, P stands for physics, C stands for chemistry, and L stands for Letter.
At present, JPCL has an impact factor of around 8, and it is a journal in the first category and the second category. It is hard to say in the future. If the impact factor can exceed 10, it may be able to stay in the same area. If the impact factor drops to 6 or 7, it may fall. For a thorough two-zone periodical.
Xu Qiu didn’t expect that Tian Qing could 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 abroad, even if Check posts can only be checked in the afternoon, so the morning is very safe.
　　 Xu Qiu guessed, she should have left a few hands with Teacher Wei...
　　 Three waves of good news in succession~EbookFREE.me~Wei Xingsi couldn't close his legs with a smile, and lay down on the back of the chair behind him triumphantly, raising his legs in a place where Xu Qiu and the others could not see.
　　 Then, Sun Wo came out and started to report.
　　 He has been making devices for the past two weeks. Based on the "tin-based perovskite battery", he has vapor-deposited eight batches of devices. The entire set of cleaning substrates, spin coating, evaporation, and testing procedures are already very familiar.
　　 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 Teacher Wei is 5%.
　　 After Sun Wo finished speaking, he turned sideways and stopped talking. Wei Xingsi stared at the image projected by the projector and tapped the table lightly.
　　 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, Wu Feifei, after you finish writing the review, take him to go through all the characterizations that should be done. Most test laboratories can do it. The main thing outside is to complete the graduation design first."
　　 With Xu Qiu and Han Jiaying in front, Wei Xingsi almost forgot that Sun Wo is what an undergraduate should look like.
