Chapter 235: The world is impermanent, the waves are too hot

"I have a scientific research support system novel ( to find the latest chapter!
In the evening, Wei Xingsi took Tang Yunkun to go happily without knowing where to go.
Xu Qiu returned to 216 and learned that the device results of the senior sister today, the highest efficiency is 1.11%.
On the way to the cafeteria, Xu Qiu and Chen Wanqing walked side by side, and the senior sister looked like she didn't want to talk.
But this time she didn't feel as lost as she was when synthesizing C1 before, and she seemed rather calm.
Maybe there is not much hope in it, or is it used to it?
"Senior sister, what do you plan to do next?" Xu Qiu asked casually.
Chen Wan gave him a clean look, her mouth opened and closed, but there was no sound.
"The efficiency of 1% is not the worst in ADA. I have seen some articles made of organic photovoltaic materials, but I dare not even release the efficiency. I only made field effect transistor devices, saying the material mobility It's not low, it can still be published." Xu Qiu tried to cite an example to comfort the senior sister. Seeing that there was no effect, he continued to analyze:
"Senior sister's system is at least a new structure. If the characterization data is completed, there should be a chance to vote for a three-zone Macromol.Chem.Phys."
Seeing that she still didn't say a word, Xu Qiu said to herself: "It's just the title of Senior Sister. It needs to be changed. It used to be the'Second District Killer', but now it is the'Second District Killer'."
Chen Wanqing chuckled, then glared at Xu Qiu, "If you can speak, talk more."
After that, she sighed lightly, "Besides, if you really want to write an article, every intermediate product must be supplemented with a bunch of nuclear magnetic, elemental analysis and other data. For a three-zone article, it feels not worth it."
"That's true." Xu Qiu nodded in response. The senior sister now has four articles in District 2 and she is naturally reluctant to spend a semester on one in District 3.
In fact, the four second-division articles of the elder sister are conservative estimates. Like the JMCA she posted, they are not strictly second-division articles, but are in a superposition of first and second districts.
Because domestic journal divisions are usually divided according to the Chinese Academy of Sciences, each journal has a major division and several sub divisions according to its positioning, and the major and sub divisions are judged independently, and there may be differences.
Take JMCA as an example. In the big category, it is the first area of ​​engineering and technology, and it is the top of the first area, and in the sub-category, it is the material science: comprehensive second area, physical chemistry second area, energy and fuel first area.
Some schools divide journals according to major categories, so JMCA is one area;
Some are based on the sub-categories closest to the department. For example, in the case of the Department of Materials, according to the Materials Science: Comprehensive category, then JMCA is the second district.
There are also journals that belong to the research group that have paid for themselves. Regardless of the major categories and subcategories, they are all based on the highest one, that is, regardless of the major category one area, the small category two area, or the small category one area, large category two area journals, all It can be claimed to be a district.
Obviously, this kind of journals with inconsistent large and small categories, even if they are classified as one district, will still be the bottom in one district, and the probability is not better than that of journals in the same district.
For example, Xu Qiufa’s article on AM and AEM are both the top of the major engineering technology category and the first area in the five or six sub-categories. This kind of journal is a real-world journal. The kind that doesn't go wrong.
In addition, the influence of journals will change over time, so the zoning is not static. It will be re-evaluated every year according to the influence of the journal, and it will increase or decrease.
For example, the journal Macromolecules, a long-established journal founded in 1968, was once the top journal in the polymer field, but its influence is now declining very seriously. At present, the major category is Top Chemistry in the second district, and the subcategory is the first district in Polymer Science. .
For another example, the polymer "Polymer" journal, also founded in 1960, has now been reduced to the third major category of chemistry, and the second category of polymer science.
It stands to reason that such names with a single word are usually very NB existences, such as the top CNS, "Cell", "Nature", and "Science". However, with the passage of time, a generation of new publications is replaced by an old one. , There are always some old journals whose godheads are shattered and fall from the supreme position to the world.
It can only be said that the world is impermanent, and the late waves are too fierce.
After dinner, Wu Feifei, Tian Qing, Duan Yun and the others returned to the dormitory to rest. Xu Qiu, Chen Wanqing, and Sun Wo returned to 216.
Chen Wanqing adjusted her mentality and determined to temporarily put down the C1 and C4 systems to prepare for the subsequent experiments.
She took the initiative to find Xu Qiu and asked: "I plan to redesign the molecular structure of A-D-A and re-plan the synthetic route. Besides introducing strong electron-withdrawing groups such as cyano and fluorine atoms, do you have any other opinions?"
Xu Qiu was originally using the computer WeChat to chat with the school girl. Hearing the girl’s call, he did a dual purpose, typing and expressing the love package while thinking. After a while, he raised his head and said:

Leave aside the problem of poor photoelectric performance of the material for the time being. I think the main problem of the elder sister is that the previous synthesis path is too long. It takes six or seven full days to complete the synthesis once, and once the synthesis fails halfway, I have to start from the beginning, so I I feel it is necessary to shorten the reaction steps."
"It's true. I didn't know what to think at the time. I came up with more than a dozen synthetic steps." Chen Wanqing shook her head, and then said:
"I already have a preliminary idea about this. After I plan to design the structure of the A unit, I will search at the major reagent vendors to see if there are any useful intermediates that can be bought directly to reduce the synthesis steps. ."
"That's the truth," Xu Qiuying said: "Just like the 3D-PDI system I am doing now, there are only 568 series, but no 7 series. The reason is very simple. The corresponding side chain amine is out of stock by the manufacturer. It’s too difficult."
"Hmm," Chen Wanqing nodded and asked, "Any other suggestions?"
"After discussing with Tang Yunkun today, I also had some inspiration," Xu Qiu paused:
"When designing an ADA acceptor molecule, we must also consider the degree of adaptation of its HOMOLUMO energy level structure to the donor material. As far as I understand it, the energy level structure of the final acceptor material is mainly determined by the central D unit. The stronger the electron-withdrawing ability of unit A, the narrower the band gap, and the deeper the HOMOLUMO energy level.
I think this is also the core advantage of A-D-A molecules. The band gap and light absorption range can be easily adjusted. "
"I will consider this," Chen Wanqing nodded thoughtfully, "You can use DFT to simulate it before doing it."
After a while, she asked expectantly: "Scholar, are there any more?"
"No, no, your inspiration has been squeezed dry," Xu Qiu said in a huff: "Would you like me to draw the molecular structure directly for you."
"Then dare to love it." Chen Wanqing answered.
"Is there any kind of senior sister?" Xu Qiu shook his head, helplessly said: "Wait for you to design the synthesis route, let me see."
"Okay, it's a deal." Chen Wanqing's eyes lit up.
...
Friday.
The first and fourth parts of the review article have been integrated by Xu Qiu and Chen Wanqing, and the abstract part has been written.
Since a review usually does not have supporting information (SI) and a pictorial abstract (TOC), it is equivalent to the main text part has been basically written.
It is still short of reference ordering, CoverLetter, and the unique copyright application (Copyright) and personal profile (CV) of the review article.
The sorting of references was handed over to Han Jiaying, who was far away in Zhangjiang;
CoverLetter wrote it once when writing the summary plan before, so it can be changed directly. Xu Qiu completed it in less than half an hour;
Chen Wanqing assumed the task of applying for copyright use.
All pictures appearing in the review and citing other documents must be copyrighted.
The three major journal companies, RSC, ACS, and Wiley, have different application procedures for copyright use, but they are generally similar.
Fill in the self-service online, including information such as the journal, year, volume number, issue number, and page number of the cited literature, as well as the title, author, contact information, publisher and other information of the reviewed literature.
The webpage is automatically reviewed, and the copyright file of the PDF version can be obtained directly after passing.
Finally, integrate all the PDFs into one large PDF file and upload it as a separate attachment when submitting.
In the personal profile section, there are usually review articles, and some Article type articles will also be included, that is, all or part of the author’s personal profile, including a color photo, is added to the article.
In the profile section of this review, there are only three places and five authors.
Xu Qiu, Chen Wanqing, and Han Jiaying worked together in one work, four for Tang Yunkun's newsletter, and five for Wei Xingsi's newsletter. Under normal circumstances, for double-communication or multi-communication articles, the last corresponding author is the first corresponding author.
Obviously, of the three places, Wei Xingsi and Tang Yunkun would each have one place, and the last place naturally fell on Xu Qiu.
As for Xu Qiu, Chen Wanqing, and Han Jiaying each taking a place, it is of course impossible.
This is the default rule in the academic circle.
Because both Tang Yunkun and Wei Xingsi are professors, they have both posted reviews before, and there is a ready-made version of their personal profiles, so they can be used directly or modified and supplemented slightly.
For example, Mr. Wei's personal profile:
"In XX, Wei Xingsi obtained a doctorate degree in polymer science from the Department of Materials Science and Engineering of Pennsylvania State University. From XX to XX, he was a postdoctoral fellow at Cambridge University... In XX, he joined the Department of Materials Science at Mordu University. Now, the main research direction of Professor Wei Xingsi's research group is organic and perovskite solar cells and organic-inorganic hybrid thermoelectric materials."
Teacher Tang’s personal profile is similar, including his education and scientific research experience starting from his doctorate, as well as his current work unit and main research direction.
Xu Qiu originally planned to apply his template directly ~EbookFREE.me~ but think about it carefully. He hasn't even graduated with a bachelor's degree, and he hasn't got a bachelor's degree yet, so he can't include his junior and senior high school experience.
After much deliberation, he only wrote three sentences: "Xu Qiu, an undergraduate of Magic University University, is now a student of Professor Wei Xingsi, and his main research field is organic solar cells."
No experience, quite easy.
After getting his personal profile, Xu Qiu continued to perfect the review article.
This time it is a double-correspondence author, which involves multiple work units. It is necessary to fill in teacher Tang’s personal information and work units.
In addition, at the end of the article, thank you for the National Natural Science Foundation number that sponsored Mr. Tang, and the same should not be omitted.
The organic trio worked together and finally finished the full draft version of this review before leaving work in the afternoon.
