I Have a Research Support System

Xu Qiu also looked happy when he heard the news.

Although the research team has not published a cover article before, he is no stranger to it.

With the advent of the Internet age, academic journals have become very electronic, and most papers can be independently retrieved on the Internet one by one.

Despite this, the major journal companies have maintained the tradition of publishing paper journals.

Just like paper magazines such as "Yilin" and "Reader" all have cover illustrations, academic journals such as AM and CNS will also select a representative work from several academic papers, and publish relevant The illustration of the journal was placed on the cover of the journal as a publicity.

The selected article is the cover article of the journal.

If there is any substantive reward for being the cover article, there is actually no such thing as an honor. After all, being able to stand out from dozens of articles in the first issue, at least the level of the article is top-notch in the current issue.

You can take it out to brag or something, such as:

Teacher Wei: "Hey, this year my students posted an AM cover."

A boss: "Hehe, our team just published an article on Science."

Teacher Wei: "Haha, goodbye to you (MMP)."

As for how to become a cover article, the contributor can apply by himself with a picture, or the editor can directly send a letter to invite.

Xu Qiu's article belongs to the second situation. Teacher Wei just received an invitation email from the editor.

Since it is an invitation, it can be accepted or rejected, and the decision is in the hands of the author.

If it is a cover article of a small periodical, Mr. Wei may still hesitate, because there is an additional cover fee, but the other party is a top journal like AM, so naturally there is no reason to refuse.

Wei Xingsi and Xu Qiu greeted each other, and then directly responded to the email to agree, and then said: "Tian Qing, I will leave the drawing of the cover illustration to you. After all, you have also submitted this article four times."

After a pause, he continued: "How to draw specifically, you and Xu Qiu discuss it."

Xu Qiu and Tian Qing nodded in agreement.

"OK."

"no problem."

This kind of cover is usually provided by the author himself, of course, you can also find foreign aid, just like writing and polishing SCI papers, there are also companies that specialize in this aspect.

In fact, there is not much technical content, but many scientific research institutions are not short of money, so just spend money to buy peace of mind. There are many domestic scientific research institutions, and it is not a problem to support several such companies.

After such a small episode happened, Wei Xingsi was in a good mood, and Chen Wanqing was secretly relieved.

The group will continue.

Wu Feifei reported the work of "Calcium Chloride Additive", the data is complete, and she is writing an article and intends to submit it to CC journals.

Duan Yun continued his work on "silver nanowire-doped PVDF substrate thermoelectric devices" last week. According to him, "a breakthrough has been made" and "this work is very promising."

His PPT lists a picture and a table, including thermoelectric parameters such as power factor and Seebeck coefficient.

Xu Qiu is not very familiar with the fields related to thermoelectricity. Hearing Duan Yun's words, it seems to be the case, but he doesn't know the actual situation, just like Duan Yun's previous article about "PH1000 doping of bismuth telluride" The article was also very vigorous at the time, but in the end it was an ACSAMI in the second district.

Tian Qing went to Zhangjiang to make perovskite quantum dots last week, but failed to prepare them;

Later, when the TRPL instrument arrived, she and Feifei Wu cooperated again to further study the charge transport mechanism of perovskite photovoltaic devices, and planned to write an article on this work alone.

She has previously published a related article on ACS Energy Letter, and now it is a more in-depth study.

Sun Wo is still reporting the literature, and he is still a little nervous when speaking, but compared with the previous week, he has made some progress.

At the end of the literature report, he concluded:

"Although perovskite photovoltaic materials have high photoelectric conversion efficiency, there are two problems. One problem is that lead is used, which is highly toxic and will pollute the environment. The other problem is that the perovskite phase is extremely unstable. As long as a small amount of water or oxygen is exposed, the phase transition will occur, resulting in a sharp drop in device efficiency.

Therefore, next, I plan to do research on tin-based perovskite, replace highly toxic lead element with very less toxic tin element, and develop environment-friendly perovskite photovoltaic devices. "

"Tin-based perovskite..." Wei Xingsi repeated, with a strange expression on his face, then nodded with a smile, and asked, "Is this the graduation project topic arranged by Wu Feifei?"

"Yes." Wu Feifei responded instead.

"Okay, tin-based perovskite has just started in the world, and the highest efficiency is only about 6%. There are not many requirements for undergraduate graduation projects. Let's set a small goal for you and achieve an efficiency of 5%."

This time Wu Feifei didn't answer, Sun Wo nodded slightly cautiously, "Okay."

Xu Qiu thought to himself below:

'I don't know how Wu Feifei thought about it. Let Sun Wo directly take over a brand new system. There are no early results for reference in the team. It is very difficult to produce results. '

‘However, having said that, it doesn’t really matter. As long as the data is complete for the graduation project of undergraduates, and they can analyze the pictures, more than half of them will be able to do so. We can’t ask every undergraduate to submit an SCI. '

Then, it was Chen Wanqing's turn to report, and there was only one sentence: "Last week, I made a device for C1, and the efficiency is not high. I am working on C4 later, and it is still being synthesized."

"Keep working hard," Teacher Wei received two good news in succession today, and said without any trouble, lying on the back of the seat, "Next, Xu Qiu."

Xu Qiu got up, inserted the USB flash drive, opened the file, picked up the laser pointer, and shook it on the projection screen, "Last week, we mainly synthesized two 3D-PDI molecules. The first-generation PDI3-B-5 system has a maximum efficiency of 4.1%. The PDI3-BX-5 system modified by the photocyclization reaction has a maximum efficiency of more than 5%..."

"5%, PDI system..." Hearing this data, Wei Xingsi smelled the article, leaned on the armrest, and stood up from the back of the seat, "Xu Qiu, what do you think?"

"I think the molecular structure can be further optimized. Of the four or five optimization schemes mentioned last week, only this one has been tried." Xu Qiu paused, and added: "In addition, there is room for improvement in the device processing technology. "

Wei Xingsi thought about it for a moment, then nodded, "Okay, then don't rush to write an article, just follow your ideas first, is there anything else?"

"No more." Xu Qiu shook his head. Last week, there was a nitrosation reaction that failed in the experiment. It can be said, but it is not necessary. Only when there is no data to report like the senior sister, will this failed The experiment was presented at the group meeting, and he said that he had a workload and was not paddling, so he naturally didn't have to.

"The other characterization data are all on Han Jiaying's side."

"Okay, Han Jiaying, come here."

Han Jiaying came on stage, and first talked about some basic characterization experiments about the two molecules synthesized by Xu Qiu, but there was no important information. The school girl checked her words and saw that Teacher Wei was not interested in these, so she simply said a few words and quickly turned the page.

It wasn't until the last piece of TRPL that she slowed down, first talked about the experimental results, and then threw out a preliminary conclusion:

"The fused 3D-PDI molecule has a higher fluorescence quenching efficiency for the acceptor, indicating that charge splitting is easier to occur between the acceptor molecules."

This conclusion was naturally drawn by Xu Qiu, but considering that Han Jiaying was responsible for the testing, data processing and drawing, he wrote this point in her slideshow.

Wei Xingsi was really interested and asked for some details.

Han Jiaying can handle most of the questions, and Xu Qiu will answer the few questions she can't answer.

"That's right, it seems that this TRPL was bought for nothing." Wei Xingsi smiled and waved to everyone, "Today's group meeting will be like this, as usual, you can order lunch at noon, I won't eat."

At the end of the group meeting, Xu Qiu was not in a hurry to leave. After the others left, he said:

"Mr. Wei, the frequency of organic synthesis in Zhangjiang is very high now. I think it is necessary to buy a microwave reactor."

"For organic synthesis, microwave reactors are indeed very important..." Wei Xingsi lowered his head and tapped his fingers on the table. After thinking for a while, he raised his head and said, "What about the price? Have you done any research?"

Xu Qiu considered his tone and said, "For imports, the most famous one is the DISCOVER series of the CEM brand, which costs about 200,000. many."

Before, he estimated that imports would only cost more than a hundred thousand yuan. Later, he checked the official website and domestic distributors carefully, and found that the minimum configuration was more than 200,000 yuan, and the high configuration was even 400,000 to 500,000 yuan. As for the modification with a microwave oven, he naturally I won't mention it to Mr. Wei, if the other party really asks him to modify it, wouldn't it be him cheating himself.

"Buy imported ones. I have used CEM brand microwave reactors abroad, and they are really good. I can also contact the purchase channel. I just bought TRPL recently, and the equipment funds may not be enough now..." Teacher Wei wrinkled Frowning, he started knocking on the table again, stopped after more than a minute, got up and said, "I'm going to make a call, just wait."

After finishing speaking, Wei Xingsi ran to the utility room alone and closed the door.

'Leave me here and run away by myself, what kind of operation is this, did you go to PY again? ’ Xu Qiu looked strange, found a stool and sat down, thinking to himself:

Mr. Wei has just returned to China, and the project funds in the group are several million. Now, after three years, with the establishment of such a large laboratory, it is estimated that only about one million funds are left.

It is true that the total amount is so much, but it does not mean that all the money can be used to buy equipment.

Because scientific research funds are divided into more than a dozen categories, the purchase of equipment can usually only be reimbursed with the equipment fee in the project, and cannot be used together. For example, it is not feasible to use travel expenses to buy equipment.

Now it seems that the equipment fee is probably not enough, and I don't know what method Mr. Wei can think of.

Xu Qiu sat on the chair and thought wildly for more than ten minutes, and finally heard the sound of the utility room door opening.

Wei Xingsi smiled and said in a relaxed tone, "It's done."
