Chapter 189: Eve of winter vacation

After spending another day, Xu Qiu integrated the outlook part into the review plan, and the senior sister converted all references into Wiley format and sorted them in order of citation.
After completion, the two checked each and corrected several text errors.
Since then, the final version of the draft plan was officially released.
As for the author, the two are tentatively set to be one. He is in the front and the senior sister is in the back. Han Jiaying mixes three works, and Wei Xingsi four works.
Afterwards, they handed the plan to Teacher Wei for review.
Teacher Wei only slightly changed the next few words and formatting issues, and saved the file to his computer, and then asked:
"From the beginning of the next semester, the non-fullerene system will be implemented. Where do you plan to start and do you have a plan for future research?
Obviously, he is more concerned about Xu Qiu's future scientific research results in experiments than a review article.
At his level, simply stacking the number of articles has made it difficult to improve his status in the field of scientific research.
Wei Xingsi pays more attention to masterpieces that can be shot, or highly cited articles, similar to the AM by Xu Qiufa and the CM by Feifei Wu.
Review articles, unless they can be published in the top issue of Chem. Rev., or even if they are published in ordinary journals, it is still not enough.
"We plan to..." Xu Qiu retelled with Teacher Wei the thoughts he had previously discussed with the senior sister.
Then he introduced his next idea, which is "the space in the review plan is too small to be written", "multiple PDI molecules..."
As soon as he said it, Teacher Wei beamed his eyes and showed great interest: "It sounds good, have you considered the difficulty of synthesis?"
"I have considered that the difficulty of synthesis is somewhat high, and the final yield may be relatively low, but this needs to be done specifically to know." Xu Qiu said.
Afterwards, the two discussed this idea for more than ten minutes. In the process, his idea improved a lot.
Xu Qiu estimated that if it wasn't for the holiday now, Teacher Wei would definitely let him start the experiment immediately.
It seems that he has a deep obsession with the PDI series.
He also found that even though Mr. Wei did not conduct experiments on the front line, his theoretical foundation was still very solid. At least the two of them had no communication barriers when discussing.
There is no such a situation where I say a proper noun, you think about it for a long time, and finally ask "what does the replacement of ortho position mean".
After that, Chen Wanqing made a report.
When Wei Xingsi learned that she was planning to "challenge the A-D-A series of small molecules alone", he shrank his neck back and his eyes widened in surprise.
Then, when she heard that "there is no specific experimental idea yet", he nodded, changed his expression, and made an expression of "it is true".
Xu Qiu smiled inwardly, and after getting acquainted with Teacher Wei, he found that he was a man of love, not many twists and turns, and he would say everything face to face or reflect on his expression.
The elder sister hurriedly finished the report. Teacher Wei didn't say much, and only said one sentence: "When I come back from the New Year holiday, show me the specific scientific research plan."
...
The review of the plan was over, and Xu Qiu didn't take time off, so he went to help Han Jiaying change the article.
She has two jobs in her hands. The first one is the relatively high-performance P3T system, with an efficiency of over 7%, and the target journal is JMCA.
Xu Qiu found that there were too many articles, and the journals that went back and forth were just these. Most of them were old journals, and new ones were relatively few.
In recent years, many new journals have been published. Perhaps in the future, academic journals will flourish.
Although it was the first time for the younger sister to write an essay, it was much less effort to change it than for him.
No way, the skill of English is very important for people doing scientific research, especially when writing SCI papers.
In reality, there are even specialized SCI paper editing companies. When the author's English expression skills are poor, he only needs to write out the general meaning and hand it over to a specialized company for editing.
Xu Qiu has not participated in specific, and the charging situation is not very clear. It may cost hundreds or thousands of dollars for one article. Now the language and chart editing of SCI papers have formed a large industrial chain.
However, such cases are more common in medical-related research fields.
Maybe the research group for medical research is sufficiently funded, not bad?
In addition, it is worth mentioning that although the molecules of P3T and P5T are similar to PCE11, that is, P4T.
But their difference lies in the number of thiophene units on the main chain, and it is generally believed that the modification of the main chain of the molecule is more innovative than the modification of the side chain.
Therefore, in terms of novelty alone, these two jobs of her are higher than the job that Xu Qiu invested in AEM before.
However, due to the poor photoelectric performance of the P3T and P5T materials themselves, the efficiency is too low, and they can only be used in the second zone. There is no need to think about the first zone, which is almost impossible.
Unless this work has other bright spots besides efficiency, such as large-size, one-square-centimeter-sized devices prepared and tested in the air, the efficiency reaches 7%, and it can be compared to standard industrial production, then there is still some possibility Sex.
But to do this, based on the existing fullerene system, it may be much more difficult than simply breaking through 8% or 9% efficiency.
Therefore, few people can find another way.
...
Before the official vacation of the research group, similar to the summer vacation, Mr. Wei called all the students to have a group meeting.
He mainly asked the students about their winter vacation plans, whether they had bought tickets, and reminded students to pay attention to safety during the holidays.
Afterwards, he also raised a mouthful of Cheng Mingbo, the junior undergraduate who had joined the group with Han Jiaying, saying that he was "very dissatisfied with his performance and decided to officially expel him from the research group" and asked Feifei Wu to contact Cheng Mingbo, tell him the news.
After talking about Cheng Mingbo, Teacher Wei praised Han Jiaying by the way,
I will post an article soon after joining the group, and there are still two jobs. Keep working hard.

Wu Feifei looked depressed and asked her to inform Cheng Mingbo, which was simply salting her wound.
There are Xu Qiu, Chen Wanqing, and Han Jiaying's Iron Triangle, but what about her?
She is also responsible for the general direction of the team, but she has only one and a half people fighting, Tian Qing barely counts as half a perovskite person.
After finally waiting for a junior, he was paddling every day, and now he has been directly expelled.
Ms. Wei noticed Wu Feifei’s discomfort, and proactively said,
Next time an undergraduate or graduate student, I will give priority to recommending the perovskite field. I will definitely help her find a good helper.
Feifei Wu's face has improved a little now.
After Wei Xingsi finished speaking, he signaled everyone to report on the recent experimental progress.
Wu Feifei first reported that she repeatedly bumped into the wall when making perovskite single crystals and tried several times without success. Now she is in an indefinite stranded state.
However, she and Tian Qing’s collaborative work on
research on calcium chloride additives
and
analysis of the similarities and differences of the effects of ammonium chloride and calcium chloride additives on perovskite batteries from the perspective of charge transport mechanism.
Both studies have made preliminary progress.
Duan Yun's new work turned to research on thermoelectric devices based on N2200.
The N2200 series can be used in the field of all-polymer organic photovoltaics. It is an n-type semiconductor and can also be used in the field of thermoelectricity.
In the thermoelectric field, the status of n-type semiconductor is much higher than that of p-type. Organic donor materials usually correspond to p-type semiconductors, and acceptor materials correspond to n-type semiconductors.
Therefore, after his work report was over, Duan Yun suggested that "Xu Qiu and the others will develop new receptor materials later, which can be given to him to test the thermoelectric properties of the materials."
Xu Qiu naturally readily agreed.
...
The next day, the laboratory was cleaned, the laboratory was closed, and the holiday was officially entered.
Xu Qiu returned to the bedroom, and his two roommates had gone home.
Tao Yan’s research group has a relatively early vacation, and the teacher’s supervision is relatively loose. Their graduate students have two weeks to one month vacation, which is allocated by the students. If they choose a two-week vacation, they can get half a month’s subsidy for the research group. There are thousands of dollars.
However, most of the students chose a one-month holiday, and Tao Yan was also on this list, and he slipped back home early.
Before he left, he had an exchange with Xu Qiu. After entering the group for half a year, he had already figured out the general situation in the group. The research in the group was more applied, and the projects were mostly horizontal.
His plan is to learn more skills during graduate school, and directly ask his tutor to find a company to push it after graduation, or to enter Warwick with his status as a graduate student of Mordu Comprehensive University~EbookFREE.me~ No matter how big a factory is, it’s okay to find a friend’s company to transition through the family relationship.
In short, many choices are very comfortable.
Ren Bin left school on January 20 two days after the exam.
The graduation project will be done next semester. He has not yet found a research group.
At present, 60% of the students who are undergraduate in the Department of Materials Science and the students who go abroad have basically found the research group and started to work on the project. The remaining 40%, and almost half of the more clever students, enter the group early. Occupying the pit can relieve some of the pressure on finishing the next semester of the senior year.
On Teacher Wei’s side, no senior undergraduates came to contact him in advance this year to do the final design. This is not because of Xu Qiu. There are still cases where a teacher instructs three or four students in the graduation project, mainly because he is in the department. The wind evaluation is relatively strict. Generally, those who are mixed are not likely to choose this type of teacher. They all like the type of topic group that can paddle.
However, Ren Bin's performance is still not irritable. According to his words, "the department will always arrange for him a tutor, and I will talk about it next semester."
It's true that this kind of thing is about graduation, and the department may be more anxious than the students.
If there is a situation where students fail to graduate in batches due to graduation design problems, this can be regarded as a serious teaching accident. If it is in the news again, the impact will be even worse.
Therefore, although there are students who fail to pass the graduation design and affect the issuance of graduation certificates and degree certificates every year, the number is not large.
In this case, hard indicators such as the paper has not been checked repeatedly, the number of words in the paper is not enough, and the hard indicators such as not participating in the defense are not up to the standard.
The department wanted to pull them, but they didn't get a chance.
