I Have a Research Support System

Neither Duan Yun nor Tian Qing had PPTs, and each spoke a few words orally.

Duan Yun's work on "silver nanowire doped PVDF-based thermoelectric materials" was submitted to the Small journal last Thursday, and this week he intends to "use the previous PVDF matrix material and replace silver nanowires with nickel nanowires to prepare thermoelectric devices".

Tian Qing's in-depth research work on "perovskite charge transport mechanism" was submitted last Friday, and the target journal is JPCL.

Two articles by the two of them, plus Wu Feifei's Adv. Sci., Mr. Wei submitted three articles in a week, which was very productive.

The next job Wei Xingsi assigned to Tian Qing was to co-author a review with Professor Feng Shengdong from Lund University in Sweden. He aimed at the very hot research on perovskite materials in recent years, but people's main attention is focused on new In the research and development of materials, as well as the sprint photoelectric conversion efficiency, the kinetics of charge transport is rarely summarized.

After their discussion, they chose a more foreign-style title, tentatively set as "Carrier Dynamics of Organometallic Halide Perovskite: From Thin Films to Solar Cells", and are currently writing a review proposal, which is what Mr. Wei said The harvest when going abroad for the first time.

Of course, Tian Qing and Feng Shengdong are the main contributors to this review, with at most one Wu Feifei as an assistant, Wei Xingsi and Tnu, one is in charge of coordinating, and the other is an academician who is responsible for being a mascot and promoting manuscripts Probability of being submitted for review and acceptance.

This time Mr. Wei recruited academician Tnu, so his ambition is very big. A top journal of materials such as AM and EES can no longer satisfy him. He plans to hit a wave of Chem. Soc. Rev.

This is the masterpiece of review journals under RSC. Its status is similar to Chem. Rev. under ACS Journal Company, with an impact factor of about 40. In principle, only reviews are accepted. The number of articles per year is very small, less than 200. Journals The H-factor is around 250, that is, the number of articles with more than 250 citations exceeds 250.

In short, if you can publish a Chem. Soc. Rev., you can blow it for a year.

Speaking of it, this is also related to Tian Qing's previous intention of "not wanting to do perovskite quantum dot synthesis experiments". Teacher Wei fully referred to her wishes and arranged this new task for her. Tian Qing happily accepted it. up.

Sun Wo reported the test data of various characterization data last week. He did not make devices, so there is no efficiency data.

Wei Xingsi didn't pay much attention to Sun Wo's experimental results, because it wasn't important to him, and now he placed the lowest expectations on Sun Wo, and his thoughts were "There are already two undergraduate generals, Xu Qiu and Han Jiaying, Accepting Sun Wo is just a comprehensive review of character", anyway, as long as you know all the basic experimental operations and can help Wu Feifei do experiments.

Therefore, Wei Xingsi only asked, "Have you learned how to operate the new instruments?" After receiving affirmative answers from the other party, he nodded in satisfaction and casually gave a few words of encouragement.

Then, Chen Wanqing reported that she had a lot of experimental work last week, and she prepared six pages of PPT.

Although she was affected by the "Nature·Materials" article in the morning, she was a little worried about gains and losses, but as a second-year doctoral student, she still has the basic ability to regulate emotions.

At least on the surface, she has regained her usual composure.

However, it was revealed as soon as he opened his mouth.

The senior sister talked to the PPT view picture without emotion: "I tested..., and the result showed..., and tested..., and the result showed..., and tested..., and the result showed..."

After "testing..., the results show..." seven times, Chen Wanqing finally finished the report.

Seeing her in this state, Wei Xingsi had nothing to do with it. He was a mentor, not a counselor, let alone a psychiatrist.

When Chen Wanqing first came here, she hadn't been able to achieve results, and he could still "enlighten and enlighten" her with a black face, but now that she has achieved results, the previous methods are not very easy to use.

Wei Xingsi said, "That's right, hurry up and write the article," and then waved his hand to let Xu Qiu take over.

Xu Qiu first reported the photoelectric performance of the device he made for his senior sister last week, with the highest efficiency reaching 5.86%. Teacher Wei already knew this result, so he just mentioned a few sentences and directly mentioned it.

Then there is the data of the light source, and it is explained according to the ideas in the article, "...the weak crystallinity of 3D-PDI molecules...consistent with the TEM and DSC data...".

The last thing is the highlight, which is the TAS result of the sample test sent to Mr. Feng Shengdong.

In order to understand the results of this experiment and a picture drawn by Mr. Feng Shengdong, Xu Qiu also had a voice chat with Mr. Feng for nearly half an hour on Sunday night.

But the mechanism is the same as the exam review of "Advanced Mathematics". I forgot half of it when my head was in the examination room, and I finally scored 59 points.

Therefore, after waking up on Monday morning, Xu Qiu specially reviewed it, but when he went to the office, Teacher Wei was called urgently, which caused him to lose his train of thought.

However, when Xu Qiu operated the laser pointer to turn the page to the TAS result page, he suddenly found that the familiar feeling had returned, so he coughed lightly and began to talk incessantly:

"Using monochromatic lasers with wavelengths of 415nm and 670nm to respectively excite a single donor, a single acceptor, and a donor-acceptor blend film, using two excitation light sources with different wavelengths, it is possible to excite only the acceptor material and simultaneously excite the donor material. The effect of body, receptor material..."

"Charge dynamics of transient light absorption at 415 nm for monochromatic excitation at 415 nm and intercept at 555 nm for single acceptor films... and monochromatic excitation at 415 nm and intercept for 555 nm for blended films and charge dynamics of transient light absorption at 680 nm..."

"...bleaching bands...singular value decomposition distribution...global variable fitting..."

"The TAS results show that, unlike the fullerene derivative system, the non-fullerene system based on 3D-PDI, no matter the donor or the acceptor, will generate electron/hole pairs after being excited by light, which has great influence on the photocurrent. Contributing to the formation of..."

"After the photoelectric material in the blend film is excited by light, there are three processes, and the time scales are 1 picosecond, 240 picoseconds and 3.7 nanoseconds, corresponding to..."

After speaking the whole result smoothly, Xu Qiu felt that he had sublimated himself. Before, he was always worried that he would forget about it. Now that he gave the speech in front of everyone, he instantly felt that the data analysis and spectrum interpretation ability of TAS had been upgraded to a higher level.

Sure enough, frequent trips to give lectures in academic circles are still useful. Not only can you travel at public expense, but you can also sublimate your academic level.

Gathering his mind, Xu Qiu looked around.

Han Jiaying stared at him with wide eyes, as if saying, "Brother, although I don't understand, but I think it's amazing." Chen Wanqing was also dumbfounded, resting her chin with one hand and holding a black fountain pen with the other. , I kept writing words in the experiment notebook, and at a glance, hundreds of "Chen" characters took up a full page.

Tian Qing seemed to understand a little bit. After all, she was mainly doing mechanism research, and when she started preparing the review last week, she took some documents from Mr. Feng Shengdong, and she had a preliminary understanding of TAS methods, but she didn't say anything wishes.

Teacher Wei opened his mouth, as if he wanted to say something, but he didn't say it. He paused for a few seconds before saying, "Well, that's pretty good."

Finally, Han Jiaying appeared on the stage, and she reported the GIWAXS data. Because the structure is similar to Xu Qiu's, the conclusion is also similar.

At the same time, she also said that she completed the synthesis of her four 3D-PDI molecules last week, highlighting the workload.

...

One thirty in the afternoon.

The simulation laboratory II lasted more than four hours, and the optimization conditions of the senior sister system have been obtained, and the efficiency has broken through 6%, reaching 6.12%.

Xu Qiu mixed two suboptimal conditions into the optimal condition, and recommended it to the senior sister as a direction for further optimization.

At the same time, Xuemei's new system, the third-generation B4T-8 series, is a system with an efficiency of 9.17% obtained in the simulation laboratory last Friday, because the optimal device processing conditions are very similar to Xu Qiu's third-generation system , so he didn't directly report the optimal conditions, but asked the juniors to refer to his system and play freely.

After arranging for the seniors and juniors, Xu Qiu went to Teacher Wei's office with a USB flash drive to revise the article.

For Mr. Wei, as the corresponding author of the article, if there are any problems or mistakes in the text that are not found, and the article is discovered by other researchers after the article is published, it will be his face. The article is very energy-intensive, but Teacher Wei is very serious every time.

During the period, Mr. Wei discovered an omission in Xu Qiu, which did not list the division of labor of each author.

For the "Nature" series of articles, there are more requirements than when publishing AM before. In the article, not only the specific division of labor of each author must be indicated, but also many other additional rules, such as uploading original data and so on.

This is not difficult to write, and Xu Qiu finished it quickly:

"Xu Qiu designed, synthesized, and prepared small-molecule acceptor materials. Xu Qiu, Han Jiaying, and Chen Wanqing prepared and tested solar cell devices. Xu Qiu carried out UV-vis, PL, DSC... and other characterization methods and data analysis. Shengdong Feng performed TAS, TRPL testing and data analysis. Jiaying Han and Wanqing Chen revised the draft paper. Xingsi Wei revised the draft paper and guided the progress of the entire project. All authors discussed the experimental results and commented on the draft paper.”

It took an afternoon to modify three versions, and finally the revision was completed. Xu Qiu sent the final version to the seniors and juniors for final verification.

After 8:30 p.m., the article was submitted smoothly.

"It's finished, the fourth article," Wei Xingsi let out a long breath, "Your work is still very solid, and there is a high probability that NC will be fine, but the page fee for this article is really expensive."

"How much does it cost?" Xu Qiu asked curiously. He only knew that NC was a purely online open-source journal, and any reader could read every article on it for free. The journal company passed on the reading fee that should have been charged to readers. The author has greatly increased the page fee for the article, but he really doesn't know how much it is.

"Here, see for yourself," Wei Xingsi pointed to the computer screen, and said, "There are three tariff standards."

I saw the display on the computer screen: "3790 pounds (United Kingdom of Great Britain and Northern Ireland), 5380 dollars (American countries, florists, neon countries), 4380 euros (Europe, other countries and regions)"

Xu Qiu silently "fucked" in his heart, and the fee for posting an NC page would be 30,000 to 40,000.

You must know that NC receives about 5,000 papers a year. For this journal alone, there are two small goals in the account without rounding up...
