I Have a Research Support System

SCI articles of more than 3953,000 authors (for subscription)

On the morning of October 1st, before the holiday.

This year's National Day holiday is still going to the end as usual. This morning, we will organize a meeting, clean up the laboratory in the afternoon, and then have a holiday, and will go to work in the afternoon of October 7th.

Material One 218, a short group meeting.

Feifei Wu continued his research this week based on the two-dimensional perovskite system of the thiophene ethylamine (tea) organic spacer layer, and mainly prepared the optimal system, that is, the device with the n value of 4, and the highest efficiency reached 9.70%.

At the same time, she tested the environmental stability of the two-dimensional device with a constant temperature and humidity box, and the performance was much better than that of the three-dimensional perovskite system, but the obvious hysteresis phenomenon encountered before was still not resolved. This will be her next step. The focus of the research.

Duan Yun continued to organize the work of "cobalt nanowire doped PVDF matrix thermoelectric materials", and the progress was about 60%.

Sun Wo, based on the two-dimensional perovskite standard system of phenethylamine and n-butylamine organic spacers, only made a batch of devices this week, and the device efficiency did not break through, and it was still stuck in the early 8%.

However, he listened to Teacher Wei's opinion and took a group of tems, and found that the photos of perovskite crystals obtained by different processing methods were different, and the differences were quite obvious.

If you want to write an article, focus the analysis on morphology, and build the correlation between processing methods-morphology-device performance. Large articles cannot be published, but there is still a chance for a small sci article.

Tian Qing did not conduct experiments this week. She compiled the exciton binding energy and exciton diffusion distance data of materials including itic, h22, idic, idic-4f, etc., and prepared an article.

The workload of this job is not small, and there are new ideas, but because her work is more of a physical aspect, it is not easy to submit to journals with a biased material such as AM and jacs and chemistry.

In the end, after discussing with Wei Xingsi, she decided to try to develop in the direction of acsel, and there will still be some articles on the mechanism.

Moreover, the current real-time impact factor of acsel has exceeded 10. When the results of the Chinese Academy of Sciences are released by the end of the year, acsel has a high probability of being the top rating of a district. If it is made, it will definitely not lose.

Chen Wanqing has already written the -4cl article, and it was posted yesterday, the target journal jacs.

In addition, the senior sister was assigned a new job by Xu Qiu. She also shared with everyone at the group meeting: "I prepared three kinds of full solution processing, translucent, scratch coating, flexible, The colorful devices are...Among them, the pce10:-4cl system is the best, with an efficiency of 6.17%..."

Immediately afterwards, Xu Qiu reported on the progress of his other work: "Last week, I took Mo Wenlin to prepare a batch of translucent devices with different electrode thicknesses. The strategy adopted was a double-layer electrode structure, which is one layer. About 1 nanometer of gold, and 9 to 19 nanometers of silver, the advantage of this is..."

"The final result is that with a thin layer electrode with a total thickness of 16 nanometers, the device efficiency can reach more than 10%, and the average visible light transmittance avt can reach 30%."

"For this job, my idea is to put five pictures in the text, respectively..."

Wei Xingsi was a bit emotional about Xu Qiu's work efficiency. He just mentioned an idea on Monday and got the results of the experiment on Friday. Even the article structure has been planned and completed. How can it be done quickly.

Diarrhea is not so fast.

Of course, Xu Qiu's two work can progress so quickly, on the one hand because of his high execution ability, on the other hand, it is mainly due to the factors in the direction of translucent devices, and the characterization test is relatively simple.

Obviously, the difficulty of writing and publishing articles in different fields and the working time required are also different. The subdivision of translucent devices is more time-saving.

Therefore, when comparing scientific researchers, in most cases, they are doing pk within the same field.

Otherwise, if you are a perovskite or graphene who is easy to publish articles, you will be able to compare with a high-energy physics researcher.

For high-energy physics, especially research involving large-scale instruments, such as particle colliders, it may take hundreds of thousands of people to conduct a research together for months or even years.

For example, in 2010, there was an article published on prb with 22 pages of body text, 12 of which were lists of authors and units. There were more than 3000 authors and 184 work units...

Together, they used the detector to record the first measurement results of proton-proton collisions on the Large Hadron Collider.

This is also the most authored sci paper published so far.

This kind of experiment is continuously tested. Xu Qiu guessed that they should be tested in a similar form of scheduling, such as three shifts and four shifts. Each group of people is responsible for the test for a few hours. A total of more than 3,000 people participated. In the test, there is no way to distinguish who has contributed more, so everyone's names are listed directly.

The more human society develops, the more difficult it is to explore the boundaries of cognition, and the more it is necessary to integrate the power of all civilizations.

In the direction of scientific research, it has been difficult for a single person to suppress the entire field in the era of Einstein and Newton.

Even in the direction of individual subdivision, there are many research groups in a hundred flowers, and teamwork and international cooperation are becoming more and more important.

Han Jiaying, the work of j3 has been finished. The target journal aem is going to be published this afternoon. With continuous practice, the speed of writing articles by the school girl has gradually increased, and an article has been published in two weeks.

Wu Shengnan, m-itic system articles have been submitted, the target journal jacs.

This is the first article to modify the side chain of the itic system. Only by modifying the position of the side chain, the performance of the device has been increased from 10% to 12%.

In fact, during this period of time, the novelty of postdoctoral sisters may not be able to use jacs. After all, the previous work of idic was also side-chain regulation, but there are no other journals that can be submitted. There are too many am and aem. The journals such as cm and jmca felt that the investment was low again.

In the case of ees, there are relatively few votes in the group. This is because ees of the same grade prefers to collect review articles compared to am and jacs. The editors of their journals want to use the review articles to pull up the impact factor, so if it is wrong For the review work, the difficulty of voting for ees will be slightly higher than that of am.

In addition, the school girl still has an itic-th job, and she plans to collect her leave and organize it. The main method used is side chain optimization. If it is put after the postdoctoral sister, the new ideas will be more lacking. You can only post an article with a weaker grade such as cm, adv.sci. or jmca.

Mo Wenlin is mainly helping Xu Qiu to prepare translucent devices this week, and at the same time writing her h22:itic: system article, the progress is almost 70%.

She is not familiar enough with the field of organic photovoltaics, and the writing speed of the article is naturally far behind Xu Qiu.

If you change to Xu Qiu, this ternary system article is estimated to be completed in less than a week, because it does not involve new materials and the writing difficulty is relatively low.

After the group meeting, Feifei Wu went to order the takeaway. Han Jiaying took the USB flash drive to find Teacher Wei to modify and post the article, and the others returned 216 with stools.

Xu Qiu found that although the organic photovoltaic field in the group has been showing high-light performance in recent months, an average of one or two am-level articles per month, but after this batch of articles in the group is finished, the potential of the itic system has basically been lost. Almost squeezed.

In other words, whether it is Wei Xingsi’s research group or other research groups working on non-fullerene systems to make a good article, they must change their angles. Either the efficiency breaks through a new high, or the structure is very novel, or there are other bright spots. It will become more and more difficult to post AM-level top issue articles.

No way, Xu Qiu led the team in the group to publish a large number of articles. Now the threshold in the field of organic photovoltaics has been raised very high.

When Xu Qiu and Xuemei were working on 3d-pdi before, the 8% efficiency of the non-fullerene system could be regarded as a major breakthrough, and the sci section was properly published.

And now the organic photovoltaic team in the group randomly pulls out a work efficiency that is 10% up, or even 11%, 12%, 13%.

Even the recent work published by follow-ups in the second district periodical, the device efficiency is generally more than 8%.

The current situation is almost the three thresholds of 8%, 10%, and 11%, corresponding to the general second district, the general first district, and the first district top publication.

Of course, there is a premise here, that is, to achieve such an efficient system, the molecular structure must be new. If the novel structure of the structure is average and there is no other bright spot as support, even if the efficiency reaches the standard, it will be 12%. Downshift.

For example, Xuemei’s j3 donor material is very similar to j2, except that there is one more sulfur atom in the side chain of the bdt unit. Therefore, although the device efficiency has reached 12%, it has dropped by half and cast aem.

Another example is the m-itic of the postdoctoral sister, which is a variant of itic, and the side chain modification method has been used in the idic article. Therefore, although the jacs is submitted, the probability of a medium/rejected manuscript is estimated to be 50-50. Even four or six open.

Nevertheless, Xu Qiu was not very panicked because he did a lot of homework in advance.

Now he has stood at the top of the field of organic photovoltaics for a short time. The higher he stands, the farther he can see. Many scientific research ideas pop up in his mind every day.

Xu Qiu will first select these ideas first, and occasionally discuss with Wei Xingsi;

Then provide the more feasible solutions to the simulation experiment system, allowing the simulation experimenters to work uninterrupted for 24 hours. Anyway, there is no "Labor Law" to protect them. Naturally, they will be severely exploited, and it is not even an exploitation. In terms of composition, the simulation experimenter is at best a production tool;

Finally, these data will remain in the simulation system and can be called directly when necessary.

Research on materials is essentially constant trial and error.

Xu Qiu cooperated with the system division of labor, he provided trial and error ideas, the system accelerated and simulated the trial and error process.

Finally, he found a suitable path, and then Xu Qiu gave the suitable path to his sisters to repeat it in reality and organize it into an article for publication.
