Chapter 226: Cover text

Xu Qiu also looked happy after hearing the news.
Although the research team has not posted a cover article before, he is no stranger to it.
With the advent of the Internet age, the degree of electronicization of academic journals is very high, and most papers can be retrieved individually on the Internet.
Nevertheless, the major periodicals companies still retain the tradition of publishing paper periodicals.
Just as paper magazines such as Yilin and Reader have cover illustrations, academic journals such as AM and CNS will also select a representative work from a number of academic papers, and compare relevant The illustrations are placed on the cover of the journal as publicity.
The selected article is the cover article of the journal.
To say that there is no substantive reward for being a cover article, it is an honor. After all, it can stand out from dozens of articles in one issue, at least the level of the article is top in the current period.
It can be used to brag or something, such as:
Teacher Wei: "Hey, my students posted an AM cover this year."
A certain boss: "Hehe, our group just posted a science article."
Teacher Wei: "Haha, goodbye to you (MMP)."
As for how to become a cover article, the contributor can apply for it with pictures, or the editor can send an invitation directly.
Xu Qiu's article belongs to the second situation. The invitation email that Teacher Wei just received 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 journal, Teacher Wei may hesitate a bit, because the cover fee is extra, but the other party is a top journal like AM, so naturally there is no reason to refuse.
Wei Xingsi and Xu Qiu greeted them, and directly replied to the email to agree, and then said: "Tian Qing, the drawing of the cover illustration will be left to you. After all, you have also put up four works for this article."
After a pause, he continued: "How to paint specifically, you discuss with Xu Qiu."
Xu Qiu and Tian Qing nodded in response.
"Ok."
"no problem."
This kind of cover is usually provided by the author. Of course, you can also find foreign aid. Just like writing and polishing SCI papers, there are companies that specialize in this area.
In fact, there is not much technical content, but many scientific research institutions are not short of money, so you should spend money to buy it without worry. There are many domestic scientific research institutions, and it is not a problem to feed several such companies.
After such a small episode, Wei Xingsi was in a good mood, and Chen Wanqing also secretly relieved.
The group will continue.
Wu Feifei reported on the work of "Calcium Chloride Additives", the data is complete, and she is writing an article and intends to submit it to CC journal.
Duan Yun continued his work on "Silver nanowire-doped PVDF-based thermoelectric devices" last week. According to him, "a breakthrough has been made" and "this work is very promising."
His PPT listed a picture and a table, including power factor, Seebeck coefficient and other thermoelectric parameters.
Xu Qiu is not very familiar with thermoelectric-related fields. Hearing Duan Yun said it is quite similar, but I don’t know how it actually is, just like the previous article by Duan Yun about "Bismuth Telluride PH1000 Doping" The article, at that time, was also able to blow hard, and finally ended up with an ACSAMI of the second district.
Tian Qing went to Zhangjiang to make perovskite quantum dots last week, but the preparation was not successful;
After the TRPL instrument arrived, she and Feifei Wu collaborated again to further study the charge transport mechanism of perovskite photovoltaic devices, planning to take out this work and write an article separately.
She has previously published a related article on ACSEnergyLetter, and now it is a more in-depth study.
Sun Wo is still reporting in the literature, and speaking is still a bit nervous, but compared with the previous week, there has been a slight improvement.
At the end of the document report, he concluded:
"Although perovskite photovoltaic materials have high photoelectric conversion efficiency, there are two problems. One problem is the use of lead. Lead is highly toxic and pollutes the environment. The other problem is that the perovskite phase is extremely unstable. As long as it is exposed to a small amount of water or oxygen, a phase change occurs, causing a sharp drop in device efficiency.
Therefore, next I plan to do research on tin-based perovskites, replacing the highly toxic lead with tin with very little toxicity, and develop environmentally friendly perovskite photovoltaic devices. "
"Tin-based perovskite..." Wei Xingsi repeated it, his face was a little weird, and then nodded with a smile, and asked, "Is this the graduation design topic arranged by Feifei Wu?"
"Yes." Wu Feifei responded.
"Yes, now the international tin-based perovskite has just started, and the highest efficiency is only about 6%. There are not many requirements for a graduation project for undergraduates. Set a small goal for you to achieve 5% efficiency."
This time Feifei Wu did not answer, Sun Wo nodded slightly, "Okay."
Xu Qiu thought to himself below:
‘I don’t know how Wu Feifei thinks about it. Sun Wo directly took over a brand new system. There are no early results in the team to refer to. It is very difficult to produce results. ’
‘However, having said that, it doesn’t really matter. As long as the graduation design of undergraduates is complete, more than half of them will be able to analyze the picture and speak. It is not necessary to require every undergraduate to issue SCI. ’
Then, it was Chen Wanqing's turn to report, with only one sentence: "I made C1 components last week, but the efficiency was not high. I will do C4 later, but I'm still synthesizing."
"Keep on going," Teacher Wei received two good news in succession today. He didn't get into trouble, lying on the back of the seat, and said, "Next, you come, Xu Qiu."
Xu Qiu got up, inserted the U disk, opened the file, picked up the laser pointer, and shook on the projection screen. "Last week, two 3D-PDI molecules were synthesized. The first generation PDI3-B-5 system has a maximum efficiency of 4.1%. The PDI3-BX-5 system modified by photocyclization reaction has the highest efficiency of over 5%..."
"5%, PDI system..." Hearing this data, Wei Xingsi smelled the smell of the article, holding on to the armrest, and supporting the edge from the seat back, "Xu Qiu, what do you think?"
"I think the molecular structure can be further optimized. I have only tried this one of the four or five optimization solutions mentioned last week," Xu Qiu paused and added: "In addition, there is room for improvement in the device processing technology. "
Wei Xingsi considered for a moment and nodded, "Yes, then don't write an article in a hurry. Do it according to your ideas first. Is there anything else?"
"Nothing." Xu Qiu shook his head. Last week, there was another nitration reaction that failed in the experiment. It can be said, but it is unnecessary. Only when there is no data to report, like the senior sister, will this fail. The experiment was taken at the group meeting, indicating that he had a workload and was not paddling, so he naturally didn't need it.
"The other characterization data are on Han Jiaying's side."
"Yes, Han Jiaying, come here."
Han Jiaying first talked about some basic characterization experiments on the two molecules synthesized by Xu Qiu. There was no important information. The school girl looked at her words and looks and saw that Teacher Wei was not interested in these, so she quickly turned the page after a few words.
It wasn't until the last TRPL piece that she slowed down, first said the results of the experiment, and then threw out a preliminary conclusion:
"The fused 3D-PDI molecule has a higher fluorescence quenching efficiency for the receptor, indicating that the charge splitting between the receptor molecules is easier."
Naturally, Xu Qiu came to this conclusion, but considering that Han Jiaying is responsible for testing, data processing, and drawing, he wrote this in her PPT.
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 that she can't answer.
"Yes, it seems that this TRPL was not bought in vain." Wei Xingsi smiled and waved his hands to everyone. "It's like this for today's group meeting. It's the same. You order lunch for lunch. I won't eat it."
After the group meeting was over, Xu Qiu didn't rush to leave. After the others left, he said:
"Ms. Wei, the frequency of organic synthesis by Zhang Jiang is very high now. I think it is necessary to buy a microwave reactor."
"For organic synthesis, the microwave reactor is really important..." Wei Xingsi lowered his head, tapping his fingers on the table, after thinking for a while, raised his head and said: "What about the price, has it been investigated?"
Xu Qiu deliberated his tone and said: "If you import, the most famous is the CEM brand series, probably more than 200,000 yuan. If it is made in China, there is a local Modu. I contacted the sales customer service of the other party and they quoted more than 80,000 yuan. ."
Previously, he estimated that the import amount would only be more than 100,000 yuan. Later, he checked carefully on the official website and domestic distributors, and found that the minimum configuration was more than 200,000 yuan, and the high configuration even cost 400 to 500,000 yuan. As for the microwave oven modification, he naturally I wouldn't mention it to Teacher Wei, if the other party really asked him to modify it, wouldn't it be that I cheated myself.
"Buy imported ones. I have used CEM brand microwave reactors abroad. They are really easy to use. I can also contact the purchase channels. I just bought TRPL recently. Now the equipment funds may not be enough..." Teacher Wei wrinkled I frowned and started knocking on the table again. After more than a minute, he stopped, got up and said, "I'll make a call~EbookFREE.me~you wait."
After speaking, Wei Xingsi ran to the utility room alone and closed the door.
‘Leave me here and ran by myself. What kind of operation is this? Did you go to PY again? Xu Qiu's face was strange, he found a stool and sat down, thinking to himself:
Teacher Wei has just returned to China, and his team has a project fund of several million. Now, after three years, to set up such a large laboratory, it is estimated that the fund is only about one million.
The total amount is so much, but it does not mean that the money can be used to buy equipment.
Because scientific research funds are divided very carefully, there are more than a dozen categories. The purchase of equipment can usually only be reimbursed by the equipment fee in the project, and cannot be mixed. For example, it is not feasible to buy equipment with travel expenses.
Now it seems that the equipment cost is probably not enough, and I don't know what method Teacher Wei can think of.
Xu Qiu sat in a chair, thinking about it for more than ten minutes, and finally heard the door opening of the utility room.
Wei Xingsi smiled, with a relaxed tone, "It's done."
