Chapter 168: There is a school sister on the left and a school **** the right

　　 One group meeting every week.
　　 Wu Feifei's article on "lead thiocyanate additive" has been completed.
　　 Originally she planned to vote on Sunday, but yesterday Chen Wanqing moved a step faster and found Teacher Wei in advance.
　　 Then, Teacher Wei changed the article until the evening. After all, he was in his forties, unlike a young man in his twenties.
　　After working hard for a day, my energy has been drained, and finally I can only edit Wu Feifei's article on Monday.
　　 Wu Feifei’s work, I plan to submit a paper to Chem.Comm., CC for short.
　　CC is a second-district journal under RSC. Although the impact factor is only about 6, the level of the journal is still good.
　　 It is relatively oriented towards chemistry, with short length and quick review of manuscripts. It can be regarded as a lower-level journal of JACS and German Application.
　　 In the process of reading the literature, Xu Qiu discovered that in the field of organic photovoltaics, there are not many articles published in the journal CC.
　　 Therefore, when he wrote the article before, he didn't think about voting on this in the past.
　　 After all, regardless of the underlying rules or other reasons that caused this phenomenon, when an old journal does not receive a lot of manuscripts in a certain field, it is better not to be hard-headed.
　　 If it is a new journal, it may also be because of its low popularity, or because researchers are concerned about its lack of division.
　　 Submit an article and choose a journal with a large number of manuscripts in the relevant field. The probability of the article being published will increase a lot.
　　 In addition, after listening to the report for nearly a semester, Xu Qiu now has a good understanding of the routines in the field of perovskite photovoltaics.
　　 He feels that "I can do it on me".
　　The materials are all ready-made. They are bought and mixed, then applied, then steamed, and finally tested.
　　 High efficiency, supplement other data, organize data, and post articles.
　　The efficiency is not high. It depends on whether it can be optimized. If it can, add data and post articles. If it can’t, change to the next system and repeat the cycle.
　　 But, he just thought about it.
　　 Now, he has a senior sister on the left and a senior on the right, so he is really reluctant to leave.
　　 Duan Yun's work has also improved, and Mr. Wei rarely smiled at him.
　　 From the tone of his chat with Teacher Wei, Xu Qiu can roughly infer that he can't post a big article in this work. It is estimated that it is the level of ACSAMI in the second area of ​​the crane.
　　 Anyway, it is a job. If it is published successfully, Duan Yun will be one step closer to graduation.
　　 He doped n-type and p-type bismuth telluride powder in the commercial PH1000, and the prepared thermoelectric materials showed high power factors, reaching 70 and 40 microwatts per meter per square Kelvin, respectively.
　　Like the photoelectric conversion efficiency in the photovoltaic field, the power factor is an important indicator for evaluating the quality of materials in the thermoelectric field.
　　 Of course, the higher the power factor, the better.
　　 But because there is no uniform international standard for its measurement methods, unlike the photovoltaic field, which can be calibrated with standard silicon cells, the values ​​measured by different research groups may vary greatly under the same experimental conditions in the thermoelectric field.
　　 Therefore, in the field of thermoelectricity, data of the same order of magnitude are generally considered to be not much different.
　　 It is also difficult to set a threshold with an absolute value of a physical quantity like the photovoltaic field.
　　 For example, in the current organic photovoltaic field, an efficiency of 10% is a threshold. The thermoelectric field cannot be compared. If the power factor exceeds XX, it is a zone.
　　 At this time, if you want to publish a big article in the thermoelectric field, in addition to the experimental data itself, you must also tell the story well, which will test the author's writing skills.
　　 After Duan Yun ended, Wei Xingsi asked:
　　 "Tian Qing, do you have anything to say?"
　　 "No, I was writing an article last week, and I can almost finish it this week."
　　 "Where are you Chen Wanqing?"
"No."
　　 "Xu Qiu?"
"No."
　　 There are three "no"s in a row, including Wu Feifei who only briefly said a few words at the beginning, only Duan Yun said more.
　　It is mainly because the small partners in the research group have concentrated on writing articles recently.
　　 Although Xu Qiu has experimental data, he does not need to talk about it himself.
　　 In the past two weeks, the results of organic experiments in the group were basically reported by Han Jiaying, and she was also "exercising" her abilities.
　　 "Han Jiaying?"
　　 "Yes, I have."
　　 The school girl hurriedly responded, got up and inserted the U disk into the big office computer.
　　The content of her report consists of two parts.
　　 Part of it is her own work. Currently, she is still in the stage of optimizing the device performance, making about two batches of devices per week.
　　 Currently, the highest efficiency of her two systems is 6.27% and 6.74% respectively.
　　 Working hard again, there is a certain possibility that Xu Qiu can reach the target set by Xu Qiu, 6% and 7%, and there will be hope for two chapters.
　　 The other part is the job Xu Qiu arranged for her, which is to help him do supplementary experiments.
　　 Judging from the current progress, the data can be completely filled when the light source ends this week.
　　 Besides, there are only four experimental data left, so I don’t have to be too rushed. If I can’t say this week, I can still paddle properly.
　　 During the report, Teacher Wei asked:
　　 "How about the molecular weight of the material P3T? How much is it? Is it high?"
　　 "Probably..." Han Jiaying couldn't answer, and looked at Xu Qiu for help.
　　" This is the latest synthesis, and GPC has not been tested yet, but from the perspective of the product morphology, yield, and post-processing process, the number average molecular weight should not be less than 20,000 ~ EbookFREE.me ~ Xu Qiudao.
　　 "Well, let's test GPC if you have time."
"it is good."
　　 Although there should be no time to test this week, Xu Qiu still responded first.
　　 Anyway, when the group meeting is held next week, Mr. Wei probably forgot about it.
　　 In fact, this is also a habit left by Mr. Wei in his early scientific research. When he was doing synthesis, after he got the polymer, he liked to go through the characterization of nuclear magnetism and GPC first.

After the 　　 group meeting, Chen Wanqing found Xu Qiu and asked, "Are you free?"
　　 "What's the matter?" Xu Qiu asked in confusion.
　　 "I want to discuss with you about my next job." Chen Wanqing said.
　　 "Your new job, isn't it about testing the light absorption spectra of P4T-2OD materials under different temperature processing conditions?" Xu Qiu asked.
　　 "But is this kind of data a bit thin?" Chen Wanqing said.
　　 "The highlight is this unique experimental phenomenon. A unique feature that is different from the traditional system was discovered on high-performance materials. I think it is enough to post a small article on the second district."
　　 Xu Qiu thought for a while, and said casually:
　　 "In addition to measuring the thin film, then measuring the solution at different temperatures?"
　　 "Yes, this idea is feasible." Chen Wanqing took a note, and then asked expectantly:
　　 "Boy, do you have any other ideas?"
　　 Xu Qiu stared at her for a while, the senior sister stared at him without flushing and heartbeat.
　　 I'm really scared of you, Xu Qiu turned away his eyes helplessly, thinking for a moment, the "school sister style" inspiration spurted out:
　　 "You can use TEM assistance, you can also study P4T with different side chains, even if you want, P3T, P5T are both possible..."
