Chapter 277: Create the strongest undergraduate graduation thesis

On Monday, the group will meet as usual.
This time the group meeting was very brief, and it was over in less than half an hour.
Feifei Wu and Wo Sun took a few minutes to report on the progress of the experiment last week: "With...characterization, the efficiency of the two-dimensional perovskite system of isobutylamine has increased to 7.5%."
Teacher Wei said:
You will work hard to achieve the efficiency above 8%. I contacted Feng Shengdong of Lund University in Sweden, and you sent a batch of 2D perovskite samples to him and asked him to help with the measurement. See if we can dig out some mechanism. Light source testing is also done. This time we will try to produce a big article and make more efforts to rush AM."
Because of the poor stability of 3D perovskite materials, Mr. Wei never thought about leaving the laboratory for testing. The current 2D perovskite materials have good air stability. As long as they are sealed, cross-border testing and light source testing are good. No problem.
Duan Yun sent back the nickel nanowires that were suspected to be problematic to the manufacturer, and the test report has not yet been issued. As for his new idea, that is, to study PVDF-based thermoelectric materials doped with one- and two-dimensional materials, there is no result yet.
Tian Qing steadily wrote the review, and the review plan she submitted has not yet come out. But there should be results soon, because this kind of plan is not reviewed by the reviewer, but by two journal editors, which is relatively faster.
Chen Wanqing and Han Jiaying have been doing synthesis in Zhangjiang last week, and they have not yet obtained the final product. The younger sister is because the synthesis path is relatively long, while the younger sister is doing the polymerization reaction and the post-processing process is longer. Neither of them had any experimental data, so they each reported orally.
Xu Qiu wrote articles for N days in a row, and just cast them on Sunday, and did not experiment.
In the end, Wu Shengnan was the one who talked the most.
"Last week, based on my previous research work, I invested in two polymerization reactions, trying to synthesize two conjugated polymer materials with the same π-conjugated main chain and different side chains, namely P() and P(TCEC). ), they are all conjugated systems based on the triphenylamine structure."
Xu Qiu looked up and glanced at her synthesis route at random. He was a little puzzled. Why were the reaction conditions so familiar. Upon closer inspection, he found that Wu Shengnan used the common Suzuki coupling reaction of Xu Qiu and the others for polymerization. He couldn't help feeling: "For the synthesis of conjugated polymer materials, the versatility of Stille and Suzuki reactions is still very strong."
"At the same time, I repeated the method of preparing MAPbI3 quantum dots by the solution method in the literature, dissolving MAI and PbI2 in DMF solvent, and adding a certain amount of oleic acid surfactant to form a precursor solution, and then taking an appropriate amount of the precursor solution Adding the poor solvent ethanol to form perovskite quantum dots, but the experiment failed..."
Tian Qing gave a snicker next to her. This is the experiment she failed before. She completely repeated the literature at the time, but did not repeat it.
Wu Shengnan didn't believe in evil, so he tried again. As expected, it failed. No way. The perovskite material itself hasn't been long since the rise of perovskite materials. The research on quantum dots has just started, and everyone is crossing the river by feeling the stones.
Wu Shengnan continued to report: "The introduction to the first part of the literature review has been completed, and the second part is about half completed."
"This week I plan to try the thermal injection method to prepare perovskite quantum dots, and then react the two polymers cast last week to process them, test the UV-vis spectrum of the product, confirm its light absorption range, and test the fluorescence emission through PL. Performance, and finally TRPL combined with integrating sphere to test the absolute fluorescence quantum yield."
"However, the integrating sphere has not arrived yet..."
"Xu Qiu, when will the integrating sphere arrive?" Wei Xingsi asked.
"Qiu Heming said to come over this Friday." Xu Qiu replied.
"Well," Wei Xingsi thought for a while and said, "Wu Shengnan, you will prepare a few more samples this week, including P3HT in the organic field and simple PDI molecules that can be used as standard samples to verify the accuracy of the integrating sphere test data."
After lunch, Chen Wanqing, Han Jiaying and Wu Shengnan rushed to Zhangjiang.
Xu Qiu started to write his graduation project. He opened the fund's annual project summary report written at the end of last year, which contained the Chinese versions of his four SCI articles last year.
Seeing this, Xu Qiu had an idea.
Originally, when he started the topic before, he only reported the title of the AM article, that is, he planned to use the best PCE11 system as the subject of his graduation design.
Now think about it, you can write more abundantly, put all four articles in the undergraduate thesis.
For example, the original PB4T molecule he published on ACSAMI and the side chain regulation strategy published on AEM are strongly related to the PCE11 system of AM. These three articles themselves are a systematic work split. Coming. As for the fourth article, the work of preparing battery devices with flexible substrates published in Macromolecules, although not related to the first three, is not a problem if it is listed separately at the end.
Now the description part in Chinese has been written almost, and if you do one, you will also do it. Doing four will not increase the workload. At most, it will take two or three days.
Moreover, the graduation project is outstanding, maybe you can also get an award by the way, such as "outstanding graduate", "excellent graduation thesis" or something.
Xu Qiu quickly made a decision to create the strongest undergraduate graduation thesis!
Looking at the whole country, there are only a handful of undergraduate students who can post so many high-quality articles like him. Most of these people have gone abroad, because undergraduates show such a level of scientific research, like a beautiful country’s Ivy League school Or top universities such as Cambridge and Oxford are also rushing to get them. The seniors are busy dealing with the affairs of going abroad, and generally don't invest too much energy in the domestic graduation thesis, as long as they can graduate successfully.
And Xu Qiu didn't choose to go abroad, which was regarded as an outlier among them.
After confirming the general direction, Xu Qiu calmed down and began to code.
First of all, he referred to Tian Qing's template and the doctoral dissertation reviewed before. Generally, the reviewed dissertation does not need to be returned to the original unit, so it is left in the public bookcase of the 216 office.
In addition, in the past few days, after returning to the dormitory at night, he would take a few minutes to help Ren Bin look at his graduation design. Tao Yan also came to join in the fun and showed his graduation design to Xu Qiu, so that he even though I haven't started writing yet, but my graduation project writing experience is already very rich.
In less than half an hour, Xu Qiu listed the big frame of his graduation project:
At the top is the cover, Chinese and English abstract, keywords, and table of contents.
Then there is the introduction of the first chapter, including introduction, basic introduction of organic solar cells, topic proposal and research significance.
Next, Chapters 2 to 5 correspond to four articles, including introduction, experimental part, results and discussion, and a summary of this chapter.
After that, Chapter 6 Results and Discussion, summarizing the contents of Chapters 2 to 5.
Then there are references, academic papers and research results published during the degree study, and acknowledgements.
In order to be neatly typeset, a new page needs to be opened every time a chapter is passed. Xu Qiu directly paginated the page in the template. The current number of papers is ten pages.
Next, Xu Qiu took the four tasks he had previously summarized in the project fund year and added them to the text.
The text and pictures are ready-made, just pay attention to the formatting, and add a legend, which is a simple description of the picture.
Hello everyone, our public account will find gold and coin red envelopes every day, and you can receive them as long as you pay attention. Please seize the opportunity for the last benefit at the end of the year. Public Account [Book Friends Base Camp]
The only thing that takes some time is the experimental part. This part was not introduced in detail in the project fund annual summary before. Now you need to use translation software to translate the experimental details in your article into Chinese, and simply modify it and put it into the graduation project.
Fortunately, most of the experimental details are similar. You only need to write the same experimental process once, and the rest can be copied directly, and then modify the name and dosage of the reagents used, and add a sentence such as "Stille in Chapter 3" The reaction method is the same as in Chapter 2".
In the evening, Xu Qiu completed the text of Chapter 2 and Chapter 3. The number of pages in the current paper has directly expanded to as many as 38 pages. The average number of pages in a chapter is about 15 pages. All the pictures he uses are The original picture in the SCI article is the integration of multiple pictures into one, not as exaggerated as Ren Bin, two or three separate pictures fill a page.
For Xu Qiu ~EbookFREE.me~ can be done, but it is not necessary.
Tuesday is another day for writing graduation projects without distraction.
Xu Qiu had been busy all day, and by night, the contents of Chapter 4 and Chapter 5 had been completed, and the number of pages of the paper directly expanded to 72 pages.
This number of pages, together with other parts such as the introduction, is estimated to be about 100 pages, which is more than the number of pages of an ordinary master's thesis and can reach the number of pages of a doctoral thesis.
Moreover, this is only part of Xu Qiu's work. The 3D-PDI series newly invested in NC and the non-fullerene review that has been published on ACSEL are not counted.
However, these two jobs were published late, so they can be written in their future doctoral dissertations without wasting them.
In the process of writing, Xu Qiu also reviewed his work this year, and was still a little proud of it, and she couldn't help feeling:
"The sky does not give birth to me, Xu Qiu, organic photovoltaics are like a long night, article, come!"
