I Have a Research Support System

After completing the experiment, Xu Qiu and Chen Wanqing began to prepare the PPT for the group meeting on Monday.

Teacher Wei also has format requirements for the PPT of the group meeting, and the content of the report must be in English, which should be a habit he developed abroad.

The first page needs to have a cover, and it needs to put the LOGO of Shanghai University.

If it is a work report, write Work Report in large, black and bold characters in the middle, and center it;

If it is a literature report, write Literature Report.

Below the large characters are the reporter and the date of the day.

Each slide, or slide, should draw a horizontal line on it, and mark the main content of the page, that is, write a title.

In addition, the aspect ratio should be 16:9, the number of pictures per page should not exceed three, and the pictures should be enlarged in equal proportions, generally centered or distributed horizontally.

Appropriately add concise text descriptions or tables next to the pictures.

The format of the text is Arial or Times New Roman.

Doing a good report at the group meeting is to lay a solid foundation for going out to make a report later.

The PPT for the report should show as much information as possible in the limited space.

In academic reports, researchers in other fields are usually confronted.

They may not necessarily understand the content of the report narrated by the speaker, and more get information by watching PPT.

Therefore, the production of report PPT is particularly important.

Xu Qiu didn't make PPT according to the rules in the last group meeting. Teacher Wei reminded him after the group meeting and asked him to learn the format with Chen Wanqing.

He doesn't have much experiment content this week, so PPT is easier to do.

Xu Qiu asked for her previous group meeting report from her senior, copied the first page directly, and then revised the report time and speaker.

On the second page, put the synthetic route map drawn in the Chemdraw software, about PBT4T.

The third page lists the optoelectronic properties of the two batches of devices in the form of J-V curve pictures and tables.

On the fourth page, he writes his outlook on future work.

First, he analyzed the insoluble matter in the second batch of samples, which may be caused by too long reaction time.

Because reducing the content of the reaction solvent toluene can increase the concentration of reactants, thereby increasing the reaction speed, the reaction time of 24 hours may be too long.

The reaction time can be shortened to 12, 18 hours.

Secondly, according to literature reports, the synthesis of crude products by Soxhlet extraction with chloroform is also an effective means to solve insoluble matter, which can be tried.

Finally, the photoelectric properties of PBT4T molecules are acceptable and worthy of further optimization. There are two main directions for the next molecular structure regulation:

One direction is to change the number of thiophene units, such as synthesizing PBT2T, PBT3T, PBT5T, etc.;

Another direction is to change the side chains in PBT4T, or to introduce heteroatoms, such as fluorine atoms.

Xu Qiu personally prefers the second direction, but he still lists both, and he also wants to hear Teacher Wei's opinion.

This is the second time for him to do the PPT for the group meeting, so the progress is relatively slow. When he finished it, Chen Wanqing had already completed it.

The two exchanged group meeting report documents.

After Xu Qiu checked it, she found that the senior sister's content was generally similar to his, but she merged the future content into the previous page because there were too few.

Moreover, the issue of solubility was not mentioned above. It seems that it is intended to avoid the important ones and not to mention it for the time being.

Her subsequent experimental plan is to adjust the molar ratio of the two A units in her ternary conjugated polymer system from 1:1 to 7:3 and 3:7.

Then the photoelectric properties of the three ternary conjugated polymers were compared.

Xu Qiu thought about it, the idea of ​​the experiment of the senior sister was more and more similar to her last job, almost exactly the same.

However, there is not much problem with this line of thinking, and I can still tell a story and publish an article.

It’s just that there are relatively few new ideas, and it is produced purely by workload. If the efficiency is not high, there is a high probability that it will be an article in the second district.

Xu Qiu, you have a good idea. After reading the job outlook on the last page, Chen Wanqing said:

However, I am still a little worried about the dangers of using chloroform for Soxhlet extraction.

I've already considered this point, Xu Qiu said:

The entire reaction device is placed in a fume hood, and the reaction system is in a closed environment throughout the process, so there will be no large amount of chloroform vapor escaping.

Coupled with maintaining good ventilation indoors and wearing a gas mask, under such multiple protections, there should be no major problems.

However, I heard that chloroform will turn into phosgene in the air, and phosgene is extremely poisonous. Chen Wanqing said.

It's true that phosgene is highly toxic, but I checked it on the MSDS before, Xu Qiu said:

Although chloroform will react with oxygen under light and high temperature conditions, and will slowly produce phosgene, commercial chloroform will add about 0.6-1% ethanol as a stabilizer.

Besides, we can use nitrogen atmosphere during Soxhlet extraction, so we don't have to worry about chloroform vapor encountering oxygen.

Seeing that the senior was still hesitant, Xu Qiu said:

How about this, I will operate the first experiment and process both of our samples, if I am fine, then you will process the next batch.

In this way of rotation, there is also a rest period in the middle. Even if the poison is slightly poisoned, as long as there is no long-term exposure, the human body can relieve the toxicity through its own metabolism.

Having reached this level, Chen Wanqing had no choice but to nod in agreement.

...

After getting the senior sister done, Xu Qiu packed his schoolbag and went back to the dormitory.

It's still early today, so you can take a hot shower in the student bathroom.

Unexpectedly, on the way back to the dormitory after taking a shower, he ran into Tao Yan.

What a coincidence, why did you come back from the laboratory so early today?

The experiment ended earlier today.

How's the experiment going?

It's okay, I'm mainly doing synthesis in Zhangjiang for the past few days.

Is there an article coming soon?

It's about the same. I submitted the article when I came back from the summer vacation. Let me think about it, Xu Qiu recalled, and said:

If I remember correctly, it was voted out on August 16, but there is no news yet, and it may take another week or two to receive a reply.

Okay, when the article is published, don't forget to treat the guests. Tao Yan said.

It's not settled yet. Let's talk about it after it's officially published. My senior sister's article was rejected the first time I submitted it. Xu Qiu said:

By the way, how about you, how are you doing in Huo Xu's army? Is he good at publishing articles?

Hey, don't mention it, Tao Yan said with a sigh:

After I joined the group, I realized that it is very difficult to publish articles in my field. Most of the previous master's brothers and sisters had to hold out a core core article just before graduation, and they barely graduated.

But the advantage is that there is usually nothing to do, and it is more suitable for me as a salted fish.

Indeed, he mainly cooperates with enterprises, and there are many horizontal projects, so it is more difficult to publish articles, Xu Qiu said:

But they should be richer, and there may be a way for you to solve your work problems in the future.

It's about the same. After graduating, one of the seniors went to work in a company that cooperates with our group. Others have changed careers.
