Chapter 483: Chen Wanqing and Duan Yun's graduation preparations

I have the text volume 483 of the scientific research support system. Chen Wanqing and Duan Yun's graduation preparations will be held on Monday, March 21.
　　 In the past two weeks, because the experimental resources of the research group have been given priority to the organic photovoltaic team, the number of device preparations by the perovskite team has been relatively small.
　　 Wu Feifei took Sun Wo, Yu Ya, and Deng Hu to make only two batches of devices. As a result, based on the two-dimensional lead-tin mixed perovskite system, the efficiency has increased from the previous 6% to 6.6%.
　　 The efficiency value is quite auspicious, but the truth is a bit low, it is still more difficult to submit a good journal.
　　 However, although the perovskite team cannot make devices, now the perovskite also has a separate spin-coated glove box, and it is still possible to do a basic characterization test.
　　 Therefore, during this time, Feifei Wu and others have supplemented the characterization data of the two-dimensional perovskite system based on 75% lead and 25% tin.
　　 Next, they plan to make more batches of devices to see if the efficiency can be further improved.
If you can improve, you still have a chance to post a better article; if you can't continue to improve, you can only sort out the article according to the current experimental results, tell a good story, and then vote for an ACSAMI or the like The second district periodical.
　　 Chen Wanqing and Duan Yun, their recent appearance in the research group office has increased significantly.
　　 Because they are busy with graduation, including submitting thesis, waiting for thesis review, preparing for the defense and so on.
　　 Graduated from graduate school is also a problem that Xu Qiu will encounter afterwards, so he took the time to find his senior sister to learn more about the situation.
　　 It turns out that the last semester before graduation is basically full.
　　 is not always busy, but there will be some time nodes, and the corresponding tasks must be completed within the specified time. The specific timetable is:
　　 "Before March 30, complete the operations of maintaining and confirming basic personal information, uploading papers, and uploading blind review papers."
　　 It is more important to maintain basic personal information. If the information is wrong, such as the wrong ID number, it will affect the subsequent receipt of graduation and degree certificates.
　　 In addition, the paper must be submitted before the end of March. If the paper is not written until the last semester of the third year of graduate school, from the perspective of time, there is a high probability that it is too late.
　　 Therefore, I usually have to spare a year to deal with graduation.
　　 In other words, the time for graduate students to truly devote themselves to scientific research is the second year of graduate school.
　　 At the beginning of the first research, you should be familiar with the laboratory and the research field, and the last research third should find a job and write a paper.
　　 "Before April 4th, the tutor completed the online review of the paper."
　　Because Wei Xingsi and Xu Qiu will go to the beautiful country to participate in the MRS meeting in April, the elder sisters must settle these matters before Wei Xingsi leaves.
　　 Otherwise, when Teacher Wei is in a beautiful country, it is not convenient to communicate. In case of emergency, he may not be able to deal with it in time.
　　 "Before April 5, the department will conduct similarity testing based on the uploaded blind review papers, and the full text of the paper with more than 10% of the citation copy ratio shall not enter the submission process."
　　 Xu Qiu found that graduate students' requirements for double checking of papers have increased a lot.
　　 The repetition rate is no more than 30% for undergraduates, and no more than 10% for graduate students.
　　 Of course, if the text is written out by yourself, or translated into English SCI papers published by yourself, there is basically no need to worry about the problem of failing to pass the check.
　　 In fact, the school gives a repetition rate of 10%, which is quite benevolent.
　　 If the essay is written entirely by myself, it would be difficult for the repetition rate to exceed 5%.
　　 For example, when Xu Qiu graduated, he wrote an undergraduate graduation thesis equivalent to a doctoral graduation thesis, completely translated his published work, and did not refer to the Chinese literature, and the repetition rate was only 1.2%.
　　 "Before April 10th, the paper will be sent to review experts for review. All doctoral students will be blindly reviewed, and some of the masters of science degree will be selected for blind review, and there is no need to send review experts."
　　 Now the school's graduation requirements for graduate students are becoming stricter and stricter.
　　 It is said that in the past, doctoral students were partially reviewed blindly and all master students were reviewed explicitly.
　　 Now, all doctoral students are blindly reviewed, and some master students are reviewed blindly. Every year, a part of the graduation thesis of graduated students is randomly checked. Once plagiarism or other academic misconduct is found, the degree will be cancelled.
　　 Xu Qiu estimated that the probability will be more stringent in the future, and perhaps a blind review of all masters and doctoral students will be implemented, and the proportion of random inspections will be increased. Even undergraduate thesis will be blindly reviewed and randomized.
　　Actually, from the perspective of reviewers, whether the papers are reviewed directly or blindly, the energy they put in is not very different.
　　 The reason why blind review was not implemented much before was probably because there were too few graduate students in China at that time, and the school did not want to prevent students from graduating.
　　 And now, on the one hand, the number of graduate students has increased, and on the other hand, the moisture of graduate students is indeed a bit high, so it is slowly increasing the difficulty of evaluation.
　　 The full implementation of blind review of papers will undoubtedly bring great pressure to graduate students.
try{mad1('gad2');}catch(ex){}　　 In blind review, the review teacher usually tends to give a fairer score.
In the case of an open review, the experts sent for review are basically the acquaintances of the instructor, unless the instructor does not want the student to graduate, or the graduation thesis is too hip, which is the kind that can’t bear to look directly at it, otherwise, most of them will give a comparison. good grade.
　　 "Before June 5, complete the thesis defense work."
　　 From April 10th to June 5th, there are nearly two months of defense time.
　　 This preparation time is still quite long, Xu Qiu guessed, mainly to prevent various accidents from happening:
　　 For example, if the paper fails to pass the review, the paper needs to be revised, the defense fails, and the paper needs to be revised or a second defense.
"On June 6, submit materials to the Academic Affairs Office of the Department of Materials, including 2 paper dissertations, 1 degree application, dissertation review book, dissertation grading sheet, dissertation grading sheet, defense committee votes, and defense Meeting minutes and resolutions, training manual..."
　　 There are still a lot of materials submitted, and most of them have to be put in the file, so hand-written materials are required, which is more troublesome.
　　 Next, Tian Qing reported on her work. Her own experiments did not come to any useful conclusions.
　　 However, the samples were sent to the Ronald team in Finland and made good progress.
The Ronald team successfully constructed the correlation between the device structure, interface charge recombination and device performance of the laminated device through the new CELIV test method, and found the correspondence between the choice of transport layer material and the interface charge recombination, and The impact of this correspondence on the performance of the final device.
　　 Based on these conclusions, it is enough to tell a story.
　　 So Tian Qing began to sort out the article, planning to vote for "Nature·Photoelectric" to give it a try.
　　 Although her submission to the "Nature" Dazi Magazine is a "investment in the high," anyway, there is a certain chance that the manuscript will be hit.
　　 After all, this work is backed by Xu Qiu's previous "Science" article, and it can be regarded as a hot spot in my research group.
　　 The Matthew effect in the scientific research circle is also very obvious, stressing that the winner takes all.
　　 For example, after the fields of perovskite and graphene become popular, even a very simple discovery can publish high-level articles.
　　 Now, Xu Qiu has already made the enthusiasm in the field of organic photovoltaics, and the cross-working with it will also increase its status.
　　 Xu Qiu has done almost no experiments in the past two weeks. He concentrated on writing articles for two weeks and finally got the first draft of the article "Nature".
　　 There are still ten days before the end of the month. Before going to the beautiful country to participate in the MRS meeting, I corrected this "Nature" article and it was no problem to vote it out.
At the 　　 group meeting, Xu Qiu used PPT to show four pictures of the text in the article "Nature" that were polished by Tian Qing, and described his own writing ideas.
　　 The other people in the organic photovoltaic team have basically assisted Xu Qiu in experiments for the past two weeks, and have not started their own work.
　　 Han Jiaying and Xu Xinjie are mainly responsible for device preparation. After repeating experiments on ten batches of devices from different batches, the highest efficiency of the binary single junction L6-Cl:Y20 system has reached 18.27%.
　　 At the same time, Xuemei was also responsible for the preparation of various conceptual devices, including flexible, large-sized, translucent, and scratch-coated devices, and took some pictures of real objects, and put them into Xu Qiu's body after the stitching was completed.
　　 Wu Shengnan took Yin Houlang, Fan Wentang and others, mainly responsible for various characterization tests, including CV, GPC, NMR, TEM, AFM, etc...
　　 Although most of the pictures and descriptions of the characterization test cannot be put into the main text of "Nature", the test still must be tested.
　　 Because higher-grade journals have higher requirements for completeness and repeatability of data, it is normal for some articles to have more supporting information than the main text.
　　 For example, in this "Nature" article, Xu Qiu's content in the supporting information contains a total of 27 pictures and tables, more than 5,000 words of description, and 12 additional references...
　　 The text is only five pages long, and there are more than ten pages of supporting information...
　　Mo Wenlin first ran NIM and got the results of third-party testing. The highest efficiency calibration value is 18.0%, which is equivalent to the results tested in the laboratory, indicating that the data tested in the laboratory is very reliable.
　　 At that time, the NIM brother who was in charge of the test was stunned when he saw the test results, and said on the spot: "Your research team is riding on a rocket. The performance improvement is so exaggerated?!"
　　 A few days ago, Mo Wenlin brought the early Y series materials calibrated by NIM, and the efficiency was only in the early 15%. Now only a month has passed, and it has directly rushed to 18%, which is really compelling.
After the group meeting, Wei Xingsi left Xu Qiu and Wu Feifei and said: "I just received a notice from the department in the morning. We need to do a safety information card for the laboratory and an inventory of fixed assets... I will forward the email to you. Up."
　　 Xu Qiu and Wu Feifei looked at each other, nodded and replied: "Okay."
　　 Then, the two returned to room 401S and checked their emails together.
try{mad1('gad2');}catch(ex){}　　 If you are a safety information card, you must first fill in a lab safety information card of Mordu University, including the name of the laboratory, the person in charge of the research group & contact information, and the experiment Person in charge of laboratory safety & contact information, laboratory safety officer & contact information, emergency telephone number on campus.
　　 Then, you need to reply the filled out EXCEL form to the department. The department will print out the information card, and you can hang it at the door of the laboratory after receiving it.
　　 The head of the research group and the person in charge of laboratory safety must be Wei Xingsi.
　　Laboratory safety officer, usually a student, is currently in a blank state, and this person needs to be determined.
　　 So Feifei Wu turned around and asked: "Security officer, who will be?"
　　 Xu Qiu thought for a while and replied: "We two, one for each? There are two laboratories. I am in charge of the organic laboratory of 520, and you are in charge of the device laboratory of 522."
　　 Wu Feifei has no comment: "Yes."
　　 After filling out the EXCEL form and sending it to the department, the two continued to look at another fixed asset inventory work, which was relatively more complicated.
　　 It is necessary to count all the furniture, instruments, and equipment in the laboratory and check them separately.
　　 The content of the statistics is very detailed, including serial number, asset number, name, model, total price, building, department, custodian, campus, storage location, precautions, etc...
　　Because all the equipment, equipment, and furniture in colleges and universities are owned by the department, school, and state, the requirements for this aspect are relatively strict.
　　Each instrument, equipment, and furniture has a corresponding fixed asset number. If it is scrapped, there will be a more complicated process to go.
　　 The reason why Wei Xingsi had packed all the furniture in the Handan office and brought it to the Jiangwan office was because it was troublesome to scrap these old furniture.
　　 As for the fume hoods and furniture in Zhang Jiang's laboratory and office, we negotiated with the department at that time, and packaged them all back to the department, so there was no relocation.
　　 The inventory of fixed assets will be carried out every once in a while. Wu Feifei had an inventory operation two years ago, and now it needs to be supplemented and revised.
　　 The workload is still quite a lot.
　　 Because the entire laboratories of Handan and Zhang Jiang have been moved to Jiangwan, the campus and storage location have been changed, so basically all the information needs to be changed again.
　　 Xu Qiu gave the first draft of the "Nature" article to several other authors in the group, including Wu Shengnan, Mo Wenlin, Han Jiaying, Chen Wanqing and others for revision, and he participated in this inventory work.
　　 On the one hand, Xu Qiu wrote two weeks of articles, and he was a little tired and wanted to change his taste;
　　 On the other hand, he is also curious about how many "family backgrounds" Wei Xingsi has.
　　 After all, if Xu Qiu chooses to stay in school in the future, he must work together with Wei Xingsi. These "family backgrounds" are also part of him.
　　 Of course, if Xu Qiu chooses another path, such as studying abroad, looking for a teaching position abroad, and returning to China after completing his studies, then Wei Xingsi's accumulation has nothing to do with him.
　　 However, these are all things in the future, far from the present Xu Qiu.
　　 After an investigation, Xu Qiu found that the fixed assets in Wei Xingsi's research group were still quite valuable.
After Wei Xingsi returned to China, all the scientific research funds added up to more than 300W, which were basically converted into fixed assets, including fixed assets provided by some departments, such as fume hoods, which were not reimbursed by Mr. Wei himself. .
　　 Specifically, there are 21 pieces of furniture. Com mainly includes fume hoods, reagent cabinets, laboratory benches, etc., with a total value of 107,470 soft sister coins.
　　 is like Zhang Jiang’s fume hood before, and one is worth 8300 soft sister coins;
　　 A large experimental platform with two sinks in the center, one worth 6680 soft sister coins;
　　A chemical reagent cabinet with explosion-proof function, a value of 6,200 soft sister coins.
　　 are all full of premium prices.
　　 It can also be seen that no matter what it is, as long as it is connected to scientific research, there is nothing cheap.
　　In the case of equipment, there are a total of 81 pieces, with a total value of 2,464,400.58 soft sister coins.
　　 is a full 246W, and there are zero and full ones.
　　 More expensive instruments, including:
　　Single-chamber thermal evaporation vacuum coating machine, 27W;
　　 Solar simulator, 22.9W;
　　 Solar cell quantum efficiency tester, 21.9W;
　　Fluorescence spectrometer, 20W;
　　 Apple portable computer, MacBookPro, 17551.5 soft sister coin.
　　 There are also cheaper ones, such as:
　　 Circulating water vacuum pump, 1050 soft sister coins;
　　 refrigerator, 1050 soft sister coins;
　　 liquid nitrogen container, 1200 soft sister coins;
　　 Semi-automatic coffee machine, 1490 soft sister coins.
　　 Something seems to have been messed up...
　　 After Xu Qiuchang has seen it, the computer is no more. The refrigerator and coffee machine can also be regarded as fixed assets...
　　PS: Short and weak, another change.
