I Have a Research Support System

Monday, material one 216.

Xu Qiu received an email from the counselor and needed to submit the mid-term report of the graduation project before this Friday.

If the previous opening report is similar to the introduction of the paper, the interim report is a bit like the fund annual report he wrote at the end of last year.

Probably the graduation project has been in progress for a month, and I will write down some progress for everyone to see.

The template is uniformly provided by the school, with a total of two pages of WORD.

On the first page, the top few lines are the basic information such as name, student number, graduation project topic, and instructor, and the bottom is a large blank space, which is used to fill in the specific progress of the graduation project.

The second page is the instructor's record of the student's thesis guidance process, including existing problems and improvement measures.

Xu Qiu looked through the documents that Tian Qing sent to him before, and after reading it, he felt that one head and two big.

His graduation project topic is based on the PCE11 AM article. On the one hand, the experiment was done last year. On the other hand, he has never discussed this work with Mr. Wei. His younger sister and senior sister helped him do some experiments.

On the first page of "The specific progress of the experiment", he can also use the time translation technique to move last year's experiment to this year.

But the discussion with Mr. Wei on the second page did not exist at all, so how can I write this, it can't be empty, saying "I am very talented, I don't need guidance".

Although it seems to be true in fact, there is no need to show it.

At this moment, Xu Qiu deeply felt that being too good was also a mistake.

So far, I can only bite the bullet and use my imagination:

On March 3rd, I ran into a problem with my experiment... What's the problem?

Assuming that I was submitting the polymerization reaction of PCE11 that day, when submitting the reaction...it seemed to be going well all the time.

By the way, you can imagine that the senior sister is voting.

Instantly inspired, she failed to make a polymer product once, and got a pot of "soup"-like product.

Then, just write "When using Stille coupling reaction to synthesize polymer materials, it is difficult to obtain higher molecular weight products".

Then, after discussing with "Teacher Wei", I got improvement measures.

The improvement measures are easy to write.

Strictly control the reaction system to be anhydrous and oxygen-free; use vacuum silicone grease to smear the bottle mouth to increase the air tightness of the system; re-steam toluene to remove water and impurities in the solvent; raise the reaction temperature to 130 degrees Celsius to fully reflux the solvent toluene; strictly control The mass ratio of monomer feeding; fast and continuous experiments, etc.

After writing a paragraph, Xu Qiu looked at it and thought there should be nothing wrong with it. 'Put yourself in the perspective of a school sister, it seems that writing is much smoother, and you can continue to do this. '

On March 13th, the problem encountered: During the evaporation process, the electrode morphology obtained was not good.

After discussing with "Teacher Wei", we got the improvement measures:

During the evaporation process, the sample stage with the ITO substrate is rotated; the evaporation rate is controlled, and the evaporation should be performed at a lower rate in the early stage of the evaporation; before the evaporation, ultrasonic cleaning of the relevant evaporation consumables, such as tungsten wire, Aluminum wire etc.

...

"It's finally finished." Xu Qiu spent more than an hour before finishing the mid-term report. Then he touched his head and felt that a few hairs had fallen out.

Looking at the content in the WORD document, Xu Qiu nodded with satisfaction, "It's very informative, and it feels so real, I believe it."

However, there is still a small problem. Every "instructor guides students' thesis process" must sign the supervisor's name once.

But now that Teacher Wei is not here, Xu Qiu had no choice but to explain the situation to him on WeChat, and then asked Wu Feifei to sign for him.

At this time, Teacher Wei should still be sleeping, and Xu Qiu did not receive a reply immediately, but he was not worried that Teacher Wei would disagree, because there are still many similar signings on weekdays.

After all, teachers in colleges and universities are also human beings, and it is impossible to stay in the office all the time. Teacher Wei is already very hardworking, but occasionally he will go on business trips or go to the hospital for treatment.

Moreover, Wei Xingsi entrusted Wu Feifei to handle matters such as financial reimbursement, and Wu Feifei handed over the errands to the first person involved in the reimbursement.

Therefore, 80 to 90% of the reimbursement invoices and appointment reimbursement forms handed over to the financial department by the group, with the signature "Wei Xingsi" on them, were signed by Wu Feifei.

Once, Wu Feifei took the reimbursement appointment form signed by Teacher Wei herself and went to the teacher in the finance department for reimbursement.

Wu Feifei could only smile in embarrassment, she couldn't say "This time I signed it myself, the previous ones were all signed on behalf of me".

After finishing the mid-term report, Xu Qiu non-stop began to fill in another document, "Completion of the Instructive Study Plan for the Major of Materials Chemistry".

No way, as graduation is approaching, although the counselor Yu Qiang no longer organizes class meetings, he will send emails such as "this week's study notes" to his classmates every week, and frequently @Everyone in the WeChat class group, so Xu Qiu Faced with all kinds of complicated affairs, I have 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 that you have taken according to the training plan.

The counselor reminded the students about this matter once at the beginning of the semester, "If the required courses are not completed, you can quickly make up this semester."

Now this is considered to be an official document to be filled out to meet the graduation review.

Xu Qiu really wanted to complain, these courses are supposed to be available in the school's information system, it would be enough to directly program a program to call the data to automatically match, or even open a webpage for students to fill in online, but now it is very difficult. Have students fill it out manually.

However, complaints belong to complaints, but you have to do it, because this is a pre-condition for graduation review. If you fail this step, you will definitely not be able to get your graduation certificate and degree certificate smoothly.

In fact, Xu Qiu probably also understands the school's approach. For these institutions, abolishing the habits that existed in the past is purely a thankless task.

Therefore, many habits of the last century have survived to the present.

For example, when filling out the student status file, there was a column of "personal identity". When Xu Qiu first saw it, he looked confused. What the hell is this?

It is said that an adult's body contains about 70% water. Could it be possible to write H2O?

Later, Xu Qiuqian took a look and realized that this saying has existed for decades. Now, except for writing files, it is used in basic places, and basically no one mentions it.

For another example, many organizations prefer paper documents.

Just like the application for the National Natural Science Foundation of China and the application for the Modu Light Source Machine Time, they are all based on paper documents. The documents must be printed out, bound and mailed. The postmark shall prevail, and the electronic version of the submission is only for keeping files.

After Xu Qiu finished handling these chores, he took time to prepare several effective layer solutions of the chloroform/dichlorobenzene solvent system, and the whole morning passed like this.

Afterwards, he prepared a batch of devices based on the optimal conditions he had explored before.

The 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 simulated laboratory, 8.43% and 7.33%.

During the experiment, Xu Qiu took time to write articles. In addition, he also received two WeChat messages from Mr. Wei:

"I know about the signature, no problem."

"Around eight o'clock in the evening, let's discuss the PPT together."

When he saw the second message, Xu Qiu guessed that Mr. Wei should be giving a report, and planned to sharpen his guns before the battle.

After all, Mr. Wei is only the corresponding author. He is sure of the general direction of the article, but he is certainly not as clear as the first author, Xu Qiu, about the specific experimental details and design ideas.

Xu Qiu knew that the so-called "discussing it" meant asking him to talk about it, so he planned to prepare a little bit, but after looking at the PPT he made, he realized that there was no need for preparation at all. If you can grasp all the key points, you don't need to spend any more effort.

In the evening, he received a WeChat call from Teacher Wei as scheduled.

Since the call was 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 simply asked "Is the situation in the laboratory okay?" Xu Qiu said, "Everything is fine, and everyone is working hard." As for whether the other party believes it or not, I don't know.

Xu Qiu heard Mr. Wei laugh in the receiver, and then the other party said: "How is your device doing?"

"Two batches have been made, and the current highest is still about 7.5%." Xu Qiu thought for a while, and decided to save a lot, at worst, wait for Teacher Wei to come back and give him a surprise.

"Well, let's try making a few more batches," Wei Xingsi said noncommittally, "Where is Zhang Jiang doing the synthesis?"

"Chen Wanqing's new system of CH3 non-fullerene acceptors has a maximum efficiency of over 2.5%. Han Jiaying tried the microwave reactor, and the results are good." Xu Qiu selected some good news to report.

"That's okay." Teacher Wei paused and said, "I understand the general idea. I'll talk about the details when I get back. Let's talk about business first. I'm going to give a report at Lund University tomorrow, and I'll go through the PPT with you today." , Is your computer PPT open?""

"It's already opened, so I'll start talking directly." Xu Qiu responded.

Afterwards, the two compared the PPT simultaneously, 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, the quality of the call was not very good, and occasionally the sound could not be heard, so we had to hang up the call and reconnect.

There are more than a dozen PPTs related to organic photovoltaics. The two communicated for more than 20 minutes. After the end, Mr. Wei hung up the call in a hurry and went to Wu Feifei to continue discussing the perovskite part.
