Chapter 251: Maybe too good is also a mistake

On Monday, Caiyi 216.
　　 Xu Qiu received an email from the counselor and needs to submit an interim report of the graduation project before this Friday.
　　 If the previous opening report is similar to the introduction of the thesis, the interim report is a bit like the annual fund report he wrote at the end of last year.
　　 It's probably been a month since the graduation project. I have written some progress for everyone to see.
The 　　 template is uniformly given by the school, with a total of two pages of WORD.
　　 On the first page, the upper few lines are the basic information such as name, student ID, graduation project title, and instructor, and the following is a large blank space to fill in the specific progress of the graduation project.
　　 The second page is the record of the instructor's guidance on the student's thesis, including existing problems and improvement measures.
　　 Xu Qiu flipped through the documents Tian Qing had previously sent him. After reading it, he felt that one head was two big.
The topic of his graduation project is based on the article. On the one hand, the experiment was done last year. On the other hand, he had not discussed this work with Teacher Wei at all. The ideas and work were done independently by himself, most of the school girls and school sisters. Help him do some experiments.
　　 "The specific progress of the experiment" on the first page, he can also use the time shift technique to move the experiment from last year to this year.
　　 But the discussion with Teacher Wei on the second page does not exist at all. How can I write this? It can’t be left blank, which means
I don’t need guidance because of my talent.

　　 Although it actually seems to be the case, there is no need to show it.
　　 Xu Qiu feels deeply at this moment that being too good is also a mistake.
　　 Until now, I can only bite the bullet and use my imagination:
　　 On March 3, I ran into a problem doing the experiment...what's the problem?
　　 Assuming that I was casting the polymerization reaction of PCE11 that day, when the reaction...it seemed to be going well all the time.
　　 By the way, you can imagine that the senior sister is responding.
　　 was inspired in an instant, she did not make a polymerization product once, and got a pot of "soup"-like product.
　　 Then, just write "It is difficult to obtain higher molecular weight products when using Stille coupling reaction to synthesize polymer materials."
　　 Then, after discussing with "Ms. Wei", I got improvement measures.
　　Improvement measures are easy to write.
Strictly control the reaction system to be anhydrous and oxygen-free; use vacuum silicone grease to coat the mouth of the bottle to increase the air tightness of the system; re-evaporate toluene to remove moisture and impurities in the solvent; increase the reaction temperature to 130 degrees Celsius to fully reflux the solvent toluene; strictly control The monomer feed mass ratio; rapid and continuous experiments, etc.
　　 After writing a paragraph, Xu Qiu looked at it and felt that there should be no problem. ‘From the perspective of my enrolling sister, it seems that it’s much smoother to write, you can continue to do this. ’
　　March 13th, the problem encountered: During the evaporation process, the electrode shape obtained is not good.
　　 After discussing with "Ms. Wei", improvement measures were obtained:
During the evaporation process, rotate the sample table with the ITO substrate; control the evaporation rate, and perform evaporation at a lower rate in the initial stage of evaporation; ultrasonically clean the relevant evaporation consumables, such as tungsten wire, before evaporation. Aluminum wire, etc.
　　……
　　 "Finally finished." Xu Qiu worked hard for more than an hour before finishing the interim report. Then he touched his head and felt that a few hairs had fallen out.
　　 Looking at the full content of the WORD document, Xu Qiu nodded with satisfaction, "Very informative, and it feels really the same, I believe it."
　　 However, there is a small problem. Every "Instructor-to-student essay guidance process" must sign the name of the supervisor once.
　　 But now that Teacher Wei is not here, Xu Qiu had to explain the situation to him on WeChat, and then asked Feifei Wu to sign on his behalf.
　　 Teacher Wei should be still asleep at this time. Xu Qiu did not receive a reply immediately, but he was not worried that Teacher Wei would disagree, because there are still many similar sign-on-signing situations on weekdays.
　　 After all, teachers in colleges and universities are also human. It is impossible to stay in the office all the time. Teacher Wei is already very diligent, but occasionally travels or goes to the hospital for treatment.
　　 Moreover, for matters like financial reimbursement, Wei Xingsi is handed over to Feifei Wu on his behalf, and Feifei Wu then hands the errands to the first relevant person for the reimbursement.
　　 Therefore, the reimbursement invoices and appointment reimbursement forms handed over to the Finance Department in the group have the signature of "Wei Xingsi" on behalf of Wu Feifei.
　　Once, Wu Feifei took the reimbursement appointment form signed by Mr. Wei herself and asked the teacher in the Finance Department to reimburse her. She was also complained, "This time it was signed on behalf of me, why is the word so ugly?"
　　 Wu Feifei can only smile in embarrassment, and can't always say "I signed this time, and the previous ones were signed on behalf of me".
　　 After finishing the interim report, Xu Qiu started to fill in another document non-stop, "Completion of the Guidance Study Plan for Material Chemistry."
No way. Near graduation, although the counselor Yu Qiang no longer organizes class meetings, he sends emails such as "This week's work notes" to his classmates every week, and frequently @ all in the WeChat class group, so Xu Qiu Faced with all kinds of complicated affairs, it is necessary to fill in a form and submit a document from time to time.
　　 As for the specific content of this document, it is to fill in the courses I have taken in accordance with the training plan.
　　 At the beginning of the school, the counselor reminded the students once, "If the required courses are not completed, I will quickly make up this semester."
　　 This is now a formal document to be filled in to deal with the graduation review.
Xu Qiu wanted to vomit. It is reasonable to say that these courses are in the school’s information system. It is not enough to directly compile a program and call the data to automatically match. It is okay to open a web page for students to fill out on the Internet. Now it is not. Let students fill it out manually.
　　 However, I cannot fail to do it because it is a prerequisite for the graduation review. If this step is not passed, I will definitely not be able to successfully obtain the diploma and degree certificate.
　　 In fact, Xu Qiu probably understands the school’s practices. For these institutions, abolishing the habits that existed in the past is a thankless task. The benefits will not be seen, and if there is a problem, it will have to be done.
　　 Therefore, many of the habits of the last century have survived to the present.
　　 For example, when filling in the student status file, there is a column of "personal component". When Xu Qiu first saw it, he was confused. What is this?
　　 It is said that the body of an adult contains approximately 70% of water. Is it possible to write H2O on it?
　　 Later, Xu Qiuqian spent a while and realized that this statement has existed for decades. Now, except when it is used when writing files, basically no one mentions it.
　　 Another example is that many organizations like paper documents.
Just like the application for the National Natural Science Foundation of China and the application for the Magic City Light Source, the paper version of the document is the standard. The document must be printed out, bound and mailed. If the deadline is involved, it will be The postmark shall prevail, and the electronic version is submitted only for file retention.
　　 After Xu Qiu dealt with these incidents, he emptied a few effective layer solutions of the chloroform/dichlorobenzene solvent system in the middle, and the whole morning passed.
After 　　, he prepared a batch of devices based on the optimal conditions he found out before.
　　 Test results show that the highest efficiencies of the two systems are 8.32% and 7.17%, which are very close to the highest values ​​in the simulation laboratory, 8.43% and 7.33%.
　　 During the experiment, Xu Qiu took the time to write articles. In addition, he also received two WeChat messages from Teacher Wei:
　　 "I know about the signing, no problem."
　　 "At around eight o'clock in the evening, let's discuss PPT together."
　　 When he saw the second message, Xu Qiu guessed that Teacher Wei should have to make a report, and planned to grind his gun right away.
　　 After all, Teacher Wei is only the corresponding author. He is sure of the general direction of the article, but he is certainly not clear about the specific experimental details and design ideas as the first author Xu Qiu.
Xu Qiu knew that the so-called "discussion" meant for him to talk about it again, so he planned to prepare a little bit, but after looking at the PPT he made, he realized that he didn't need to prepare at all. He just looked at the PPT. If you can catch all the important points, you don't have to spend any more effort.
　　 In the evening, he received a WeChat call from Teacher Wei as scheduled.
　　 As the call came from abroad, the signal was not very good. The two "feed" each other for a few seconds before confirming that the call was connected.
　　 Wei Xingsi first asked briefly "Is the laboratory situation okay?" Xu Qiu said, "Everything is fine, everyone is working hard and conscientiously". As for whether the other party believes it or not, I don't know.
　　—
　　 Xu Qiu heard Teacher Wei laugh in the receiver~EbookFREE.me~ Then the other party said: "How is your device doing?"
　　 "I made two batches, and the current maximum is still about 7.5%." Xu Qiu thought for a while, but he still kept a hand. It's a big deal to wait for Teacher Wei to come back and give him a surprise.
　　 "Well, let's try a few more batches," Wei Xingsi said non-committal: "Are they Zhang Jiang doing synthetics?"
　　 "Chen Wanqing's new system CH3 non-fullerene receptor, the highest efficiency reached more than 2.5%, Han Jiaying tried the microwave reactor, the effect is good." Xu Qiu picked some good news to report.
"That's okay," Teacher Wei paused: "I understand it in general. I'll talk about it when I go back. Let's talk about business first. I will give a report at Lund University tomorrow. I will go through the PPT with you today. , Is your computer PPT open?""
　　 "It's already opened, then I'll just start talking." Xu Qiu responded.
Afterwards, the two of them simultaneously compared the PPT, and Xu Qiu introduced page by page. Wei Xingsi responded with "um" and "um" most of the time, and sometimes asked some questions for Xu Qiu to answer. It looks like a group meeting.
During the period of 　　, the quality of the call is not very good, and occasionally the sound cannot be heard, and I can only hang up the call and reconnect.
　　 There were more than a dozen PPTs related to organic photovoltaics. The two exchanged for more than 20 minutes. After the end, Mr. Wei hung up the call and went to Wu Feifei to continue discussing the perovskite.
