Chapter 263: There are 2 small goals in the account without rounding 4 to 5

Both Duan Yun and Tian Qing did not have PPT, and each spoke a few words.
　　 Duan Yun’s work on
silver nanowire doped PVDF-based thermoelectric materials
was submitted to the Small journal last Thursday. This week he plans to
use the previous PVDF matrix material and replace silver nanowires with nickel nanowires to prepare thermoelectric devices
.
　　 Haru Tian’s in-depth research on the "perovskite charge transport mechanism" was published last Friday, and the target journal is JPCL.
　　 Two articles by the two of them, plus Feifei Wu's article. Teacher Wei contributed three articles in one week, which is very productive.
Wei Xingsi handed over Tian Qing’s next job to write a review in collaboration with Feng Shengdong from Lund University in Sweden. He aimed at the very hot research of 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, few summarize the mechanics of charge transport.
After they discussed it, they took a more western title, tentatively scheduled to be "Study on Carrier Dynamics of Organometallic Halide Perovskites: From Thin Films to Solar Cells", and they are currently writing a review plan, which is also from Teacher Wei The gains during my trip abroad.
Of course, in this review, Tian Qing and Feng Shengdong are the main contributors, plus at most one Wu Feifei assistant, Wei Xingsi and T?nu, one is responsible for coordinating, and the other is an academician who is responsible for mascots. Increase the probability of manuscripts being submitted for review and acceptance.
　　 This time, Mr. Wei has attracted Academician T?nu, so he is very ambitious. A top publication of this kind of material can no longer satisfy him. He intends to hit a wave. 　 Rev.
This is the leading work of RSC's review journals. Its status is similar to that of ACS Journals. Its impact factor is about 40. In principle, only reviews are accepted. The number of articles per year is very small, only less than 200. The journal's H factor Around 250, that is, more than 250 articles have been cited more than 250 times.
　　 In short, you can post a .　Rev., you can play for a year.
Speaking of it, this is also related to Tian Qing’s previous intention of "unwilling to do perovskite quantum dot synthesis experiments." Teacher Wei fully referred to her wishes and arranged this new task for her. Tian Qing was very happy to accept 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 was not important to him. He now has the lowest expectations for Sun Wo. His thoughts are "Xu Qiu and Han Jiaying already have two undergraduate generals. If you accept Sun Wo, you should integrate your character." Anyway, as long as you know all the basic experimental operations, you can help Feifei Wu do experiments.
　　 Therefore, Wei Xingsi only asked, "Have you learned the operation of those new instruments?" After getting the affirmative answer from the other party, he nodded in satisfaction and casually encouraged a few words.
　　 Next, Chen Wanqing reported that she did a lot of experimental work last week, and she prepared a six-page PPT.
　　 Although she was affected by the article "Nature·Materials" in the morning, she had some troubles, but as a second-year doctoral student, she still has basic emotional control skills.
　　 At least on the surface, she has regained her usual composure.
　　 However, it was revealed as soon as he opened his mouth.
　　 The elder sister spoke to the PPT without feelings: "I tested..., the result showed that..., I tested again..., the result showed..., I also tested..., the result showed..."
　　 A total of "test..., the results show..." Seven times, Chen Wanqing finally finished the report.
　　 Wei Xingsi saw her in this state, nothing happened. He was a tutor, not a counselor, let alone a psychologist.
　　 Chen Wanqing has been unable to achieve results when she first came here, and he can still "enlighten and enlighten" her with a black face, but now she has achieved results, the previous set is not easy to use.
　　 Wei Xingsi said "Yes, hurry up and write the article", and then waved his hand for Xu Qiu to take over.
　　 Xu Qiu first reported on the photoelectric performance of the device he helped the senior sister made last week, and the highest efficiency was 5.86%. Teacher Wei already knew the result, so he said a few words directly.
　　 Then there is the data of the light source. I said it again according to the idea in the article, "...the 3D-PDI molecule is weakly crystallized...and the data is consistent...".
　　 The last thing is the highlight, which is the TAS result of the sample test sent to Teacher Feng Shengdong.
　　 In order to understand the results of this experiment and a picture drawn by Feng Shengdong, Xu Qiu also had a voice chat with Feng for nearly half an hour on Sunday night.
However, the mechanism is the same as the review of the "Advanced Mathematics" exam. After reviewing the day before, I felt that I could do it. I even had the illusion of "I can test 100 points because I only have 100 points", but the next day I forgot about half of the test room and finally got 59 points.
　　 Therefore, after waking up on Monday morning, Xu Qiu also specially reviewed it, but then he went to the office when Mr. Wei was urgently summoned, which caused him to lose his mind.
　　 However, when Xu Qiu turned the laser pointer to the page of the TAS results, he suddenly realized that the familiar feeling had returned, so he coughed slightly and began to talk endlessly:
"Through monochromatic lasers with wavelengths of 415 nm and 670 nm, separate donors, single acceptors, and donor-acceptor blend films are excited separately. Using two excitation light sources of different wavelengths, it is possible to excite only the acceptor material and simultaneously The effect of body and receptor material..."
"For a film with a single receptor, excited by monochromatic light at 415 nanometers, and intercepting the charge dynamics process of transient light absorption at 555 nanometers..., for a blended film, excited by monochromatic light at 415 nanometers and intercepting 555 nanometers And the charge dynamics process of transient light absorption at 680 nanometers..."
　　 "...bleaching zone...singular value decomposition...global variable fitting..."
"The TAS results show that, different from the fullerene derivative system, the non-fullerene system based on 3D-PDI, regardless of the donor or acceptor, will generate electron/hole pairs after being excited by light. Contribute to formation..."
　　 "After the optoelectronic material in the blended film is excited by light, there are three processes, the time scales are 1 picosecond, 240 picosecond and 3.7 nanosecond, respectively, corresponding to..."
　　 narrated the whole result smoothly. Xu Qiu felt that he was sublimated. Before, he was always worried about forgetting. Now he gave a speech in front of everyone, and instantly felt that the ability of TAS data analysis and spectrum interpretation had improved to a notch.
　　 Sure enough, it’s a bit useful for academic circles to go out often to give reports. Not only can you travel at public expense, but you can also actually sublimate your academic level.
　　 settled down, Xu Qiu looked around.
Han Jiaying stared at him with big eyes, as if saying, "Brother, although I don't understand, but I think it's amazing." Chen Wanqing was also dumbfounded, holding her cheek in one hand and a black pen in the other. , I kept writing words on the experimental record book, and at a glance, hundreds of "Chen" characters took up a full page.
Tian Qing seems to understand a little bit. After all, she is mainly doing mechanism research, and when she started preparing for a review last week, she brought some documents from Feng Shengdong, and she had a preliminary understanding of TAS methods, but she did not speak. Willingness.
　　 Teacher Wei opened his mouth, as if he wanted to say something, but didn't say anything. He paused for a few seconds before saying, "Well, it was pretty good."
　　 Finally, Han Jiaying made her debut. She reported the GIWAXS data. Because the structure is similar to Xu Qiu's, the conclusion is similar.
　　 At the same time, she also said that she completed the synthesis of her four 3D-PDI molecules last week, highlighting the workload.
　　……
　　 1:30 in the afternoon.
　　 The simulation laboratory II lasted more than four hours, and the optimized conditions for the school sister system have been obtained, and the efficiency has exceeded 6%, reaching 6.12%.
　　 Xu Qiu mixed two sub-optimal conditions into the optimal conditions, and recommended them to the seniors as a direction for further optimization.
At the same time, Xuemei’s new system, the third-generation B4T-8 series, is the 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 did not directly report the optimal conditions, but let the schoolgirls refer to his system and play freely.
　　 arranged for the school sister and school girl, Xu Qiu took the USB flash drive to Teacher Wei's office to modify the article.
For Teacher Wei, as the corresponding author of the article, if there are any problems or mistakes or omissions in the main text, other researchers found that after the publication of the article, it was his face, so although he changed The article is very energy intensive, but Teacher Wei is very serious every time.
During the 　　 period, Teacher Wei discovered an omission of Xu Qiu, not enumerating 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, but also many other additional rules, such as uploading raw data, etc.
　　 This is not difficult to write, Xu Qiu quickly finished:
"Xu Qiu designed, synthesized, and prepared small molecule receptor materials. Xu Qiu, Han Jiaying, and Chen Wanqing prepared and tested solar cell devices. Xu Qiu conducted tests and data analysis of characterization methods such as DSC...~www.mtlnovel. com~Feng Shengdong conducted testing and data analysis. Han Jiaying and Chen Wanqing revised the draft of the paper. Wei Xingsi revised the draft of the paper and guided the entire project. All authors discussed the experimental results and commented on the draft."
　　 It took an afternoon to change the three versions, and finally the revision was completed. Xu Qiu sent the final version to the school sister and school girl for final verification.
　　 After 8:30 in the evening, the article was posted smoothly.
　　 "Completed, the fourth article," Wei Xingsi exhaled, "Your work is still very solid, and NC has a high probability of no problem, but the page fee for this article is really expensive."
"How much does it cost?" Xu Qiu asked curiously. He only knew that NC is a purely online open source journal. Any reader can read each article above for free. The journal company passed on the reading fee that should have been charged to readers. The author has greatly increased the page cost of 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 on the computer screen: "3790 pounds (United Kingdom of Great Britain and Northern Ireland), 5380 dollars (American countries, flower growers, neon countries), 4380 euros (Europe, other countries and regions
　　 Xu Qiu said silently in his heart, sending an NC page fee of 30,000 to 40,000.
　　 You need to know that NC collects about 5000 papers a year. For this journal, there are two small goals for one year without rounding up...
