I Have a Research Support System

Monday, as usual group meeting.

The group meeting this time was very short and ended in less than half an hour.

Wu Feifei and Sun Wo spent a few minutes reporting on the progress of the experiment last week: After... and other characterizations, the efficiency of the two-dimensional perovskite system of isobutylamine has increased to 7.5%.

Teacher Wei said: You should work harder and strive to achieve an efficiency of more than 8%. I contacted Feng Shengdong from Lund University in Sweden. You sent a batch of two-dimensional perovskite samples to him and asked him to help test it. Let’s see if we can dig out some mechanism aspects. The light source test is also done, this time we will strive to make a big article, and work harder on AM.”

In the past, the three-dimensional perovskite material was too poor in stability, so Mr. Wei never thought of leaving the laboratory for testing. The current two-dimensional perovskite material has good air stability. No problem.

Duan Yun sent back the nickel nanowires suspected to be faulty to the manufacturer, but 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 is writing the review steadily. She submitted a review proposal to Chem. Soc. Rev., but the result of the preliminary review has not yet come out. However, there should be results soon, because this kind of proposal is not reviewed by reviewers, but by two journal editors, which is relatively faster.

Chen Wanqing and Han Jiaying have been doing synthesis in Zhangjiang last week, and neither of them has obtained the final product. The senior sister is because the synthesis path is relatively long, while the junior sister is doing polymerization reaction, and the post-processing process is relatively long. Neither of them had any experimental data, so they gave oral reports.

Xu Qiu wrote the article for N days in a row, and just rejected it on Sunday, and did not conduct experiments.

In the end, Wu Shengnan talked the most among the few people.

Last week, based on my previous research work, I voted for two polymerization reactions, trying to synthesize two conjugated polymer materials with the same π-conjugated main chain and different side chains, namely P(TPACO) and P( TCEC), they are all conjugated systems based on the triphenylamine structure.

Xu Qiu raised her head and casually glanced at her synthetic route. She was a little puzzled. Why did the reaction conditions look so familiar? After a closer look, she found that Wu Shengnan used the Suzuki coupling reaction that Xu Qiu and the others used for polymerization. The Stille and Suzuki reactions are quite versatile for the synthesis of conjugated polymer materials.

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 precursor solution Adding poor solvent ethanol to form perovskite quantum dots, but the experiment failed...

Tian Qing snickered next to her. This is the experiment she failed in before. She completely repeated the literature at that time, but she didn't repeat it.

Wu Shengnan didn't believe in evil, so he tried again, but as expected, he also failed. There was no way, the rise of perovskite material itself was not long, and the research on quantum dots was just started. Everyone was crossing the river by feeling the stones.

Wu Shengnan continued to report: The introduction of the first part of the literature review has been completed, and about half of the second part has been completed.

This week I plan to try the thermal injection method to prepare perovskite quantum dots, and then process the two polymers submitted last week, 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 an integrating sphere to test the absolute fluorescence quantum yield.

However, the scoring ball has not arrived yet...

Xu Qiu, when will the scoring ball arrive? Wei Xingsi asked.

Qiu Heming said to come over this Friday. Xu Qiu replied.

Well, Wei Xingsi thought for a while, and said, Then Wu Shengnan, you should prepare several more samples this week, including P3HT in the organic field, and simple PDI molecules can be used as standard samples to determine whether the integrating sphere test data is accurate.

After lunch, Chen Wanqing, Han Jiaying and Wu Shengnan rushed to Zhangjiang.

Xu Qiu began to prepare for 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 opened the topic, he only reported the title of AM's article, that is, he planned to use the best PCE11 system as the theme of the graduation project.

Now that I think about it, I can write more abundantly, and put all four articles into the undergraduate thesis.

For example, the original PB4T molecule he published on ACSAMI, as well as the side chain regulation strategy published on AEM, are all strongly related to AM's PCE11 system. These three articles are a systematic work in themselves. here. As for the fourth article, the work of preparing battery devices with flexible substrates published in Macromolecules, although it is not related to the first three, it is not a problem to list it separately at the end.

Now the description part in Chinese is almost finished, and it is easy to write one article, and it will not increase too much workload if you write four articles. At most, it will only take two or three days more time.

Moreover, if the graduation design is outstanding, maybe you can get an award by the way, such as excellent graduate, excellent graduation thesis and so on.

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 publish so many high-quality articles like him. Most of these people have gone abroad, because undergraduates have shown such a level of scientific research, like an Ivy League school in a beautiful country Or top universities such as Cambridge and Oxford are also rushing to get them. Seniors are busy dealing with overseas affairs, and generally don't invest too much energy in domestic graduation thesis, as long as they can graduate smoothly.

And Xu Qiu didn't choose to go abroad, so he was one of the outliers.

After confirming the general direction, Xu Qiu calmed down and began to code.

First of all, he referred to Tian Qing's template, as well as the doctoral dissertation that had been reviewed before. Generally, such reviewed papers do not need to be sent back to the original unit, so they were left in the public bookcase of Office 216.

In addition, in the past few days, when he returned to the dormitory at night, he would take a few minutes to help Ren Bin look at his graduation project. Tao Yan also came to join in the fun and showed Xu Qiu his graduation project, so that although he I haven't started writing yet, but I already have a lot of experience in writing my graduation project.

After spending less than half an hour, Xu Qiu listed the big framework of his graduation project:

The front is the cover, Chinese and English abstracts, keywords, and table of contents.

Then there is the introduction of the first chapter, including the introduction, the basic introduction of organic solar cells, the proposal of the topic and the significance of the research.

Next, Chapters 2 to 5 correspond to four articles, including introduction, experimental part, results and discussion, and a summary of this chapter.

Afterwards, Chapter 6 Results and Discussion summarizes the contents of Chapters 2 to 5.

This is followed by references, academic papers and research published during the degree program, and an acknowledgment section.

In order to arrange the layout neatly, a new page needs to be opened after each chapter. Xu Qiu directly made the pagination in the template. The number of pages in the current paper is ten pages.

Next, Xu Qiu directly took out his previous four tasks in the annual summary of the project fund and added them to the text.

The text and pictures are ready-made, you only need to pay attention to the format and layout, and add a legend, which is a simple description of the picture.

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 I need to use translation software to translate the experimental details in my article into Chinese, and simply modify it and put it into the graduation project.

Fortunately, most of the experimental details are similar. The same experimental process can be written only once, and the rest can be copied directly, and then modify the name and amount of the reagent used, and then mention a sentence such as Stille in Chapter 3 The reaction method is the same as that in Chapter 2.

In the evening, Xu Qiu finished the text of the second and third chapters. The number of pages in the current thesis has directly expanded to as many as thirty-eight pages. The average number of pages in a chapter is about fifteen pages. The pictures he uses are all The original pictures in the SCI article, that is, combining multiple pictures into one, is not as exaggerated as Ren Bin, where two or three individual pictures fill up a page.

For Xu Qiu, it can be done, but it is not necessary.

Tuesday is another day to concentrate on writing graduation projects.

Xu Qiu has been busy all day, and by the evening, he has completed the contents of Chapters 4 and 5, and the number of pages in the thesis has directly expanded to as many as 72 pages.

This number of pages, together with other parts such as the introduction, is estimated to be about 100 pages, which has exceeded the number of pages of the graduation thesis of ordinary master students, and can reach the number of pages of graduation thesis of doctoral students.

Moreover, this is only a part of Xu Qiu's work, the 3D-PDI series newly submitted to NC, and the non-fullerene review published on ACSEL were not counted.

However, these two works were published late, so they can be written in my future doctoral dissertation, and it will not be wasted.

In the process of writing, Xu Qiu also reviewed his work in the past year, and he was still a little proud, and he couldn't help but feel emotionally:

Xu Qiu was not born to me, organic photovoltaics are like a long night, article, come!
