I Have a Research Support System

In the next two days, Thursday and Friday, Wei Xingsi submitted five top-level articles in a row.

Among them, there are four AM articles, including Wu Feifei's review of 2D perovskite, Xu Qiu's IDIC system, Chen Wanqing's IEICO-4F system, Wu Shengnan's six-in-one system, and an EES article, Han Jiaying's J2 system.

Obviously, it is impossible to win all five top journal-level articles. After all, peers will fall in love and kill each other. Xu Qiu thinks it would be good to win two or three articles.

Of course, it's impossible to miss all of them.

The reason is also very simple. For example, Xu Qiu submitted a job. This job has both the highlights of "12% high efficiency" and the highlights of "new materials and new ideas". Journals such as ACSAMI and AELM have gone up.

It’s okay if one article is like this. If five consecutive articles are like this, it will form a concept similar to “precedents” in law, that is to say, it will form a reference. Then other similar jobs submitted by peers, If even Xu Qiu's work is not as good as it is, how dare you submit to a higher-level article than ACSAMI and AELM, and you may go directly to the third district.

Therefore, in a sense, peer review is also limited, and it cannot be targeted at will and give bad reviews, which will lead to the collapse of the entire field.

What's more, not all scientific researchers who deliberately make people stumble, there are still many people who focus on academics themselves.

On Friday afternoon, Wei Xingsi appeared at the door of 216, and said happily as soon as they met: "Xu Qiu, I just received an email from the editor-in-chief of AM. The article you voted for AM in the ITIC system before was selected as the cover article again. It will be published directly in the next issue. The publication speed of this article is really fast. I think the electronic version has only been online for about a month..."

For popular journals like AM, after a normal article is included in the electronic version, it usually takes several months or even more than half a year to wait in line before it can be officially published, but Xu Qiu's current article only took more than a month. It was officially published in time, which can be described as the speed of light. There is a high probability that the editor-in-chief saw this work and felt that it had great potential, so he personally shot it and advanced the round.

Similar to the fact that fiction websites have chief editors and general editors, periodical companies also have chief editors and general editors. The chief editors have a very large authority, and they are usually veterans who have been in this industry for more than ten years, and their control over academic papers is also very accurate.

In other words, the editor-in-chief does not engage in research and cannot produce outstanding scientific research work, but the ability to judge whether a job is good or bad is basically MAX.

"What about the cover?" Xu Qiu asked.

"Hmm..." Wei Xingsi turned his head and said, "Tian Qing, will I leave it to you this time?"

"Yes." Tian Qing nodded in response.

"That's all right, get it done by next Monday." After Wei Xingsi finished speaking, he handed over a dozen documents to Xu Qiu: "This is the latest document on organic photovoltaics. Recently, many people have followed the trend of ITIC."

After Teacher Wei left, Tian Qing asked, "Xu Qiu, do you have any instructions on the cover of the article?"

Xu Qiu thought about it for a while, and said: "For the composition, you can refer to the style of our previous cover article, or refer to other people's covers on the journal website. I just make a request to show that ITIC is a flat non-rich Slerene acceptors are different from traditional PCBM materials."

Tian Qing nodded and said: "No problem, I have had the experience of the first time, and now it will be much easier to do the cover for the second time."

After finishing the cover matter, Xu Qiu simply looked through the recent literature, there are more than a dozen, and there are quite a few.

These are all articles published by Wei Xingsi's research group, and all of them are articles from other research groups.

Xu Zhenghong and his IDTBR system have no big voices for the time being. They only published a JMCA. The main structure is still IDTBR, and there are not many innovations.

The number of articles related to ITIC has increased significantly, with a total of five articles.

Most of them follow the trend and use ITIC acceptors, and then find a donor material that Xu Qiu and the others have not used to match, including PPBDTBT, etc., and get 7%-9% efficiency respectively. There is not much new idea, such as involving structural modification. Sex, or bringing up any new perspectives, nothing.

Therefore, the quality of the articles is average compared to AM. The best article was sent to AFM in the first district, and the other three articles were sent to JMCA, ACSAMI and CM.

These systems Xu Qiu could have done before, but he didn't do it. The purpose was to leave it for others to eat. He couldn't break 10% of the system. Now he doesn't like it anymore.

Among these four articles, Xu Qiu had seen three of them before, and they were all manuscripts that he reviewed. Of course, he assigned the specific review tasks to the school girls in the name of "exercising manuscript review skills" With Mo Wenlin and Wu Shengnan, he was in charge of the second review.

The fifth ITIC-related article was published on AM, and it is also the only top-level article in this batch of documents, which is the work of Gong Yuanjiang's research group.

They used the ITIC acceptor in the field of all-small-molecule organic photovoltaics, that is, both the donor and acceptor materials are small molecules, and the efficiency directly exceeded 10%, reaching 10.23%, breaking the world record of the all-small-molecule system.

This is the "benefit" of carrying out multiple research directions in a research group. Once there is a hot spot to rub, you can directly use the ready-made system in the group to apply it. If it is effective, you can publish a good article.

Somewhat similar to interdisciplinary results, one result can be applied in multiple fields simultaneously.

In fact, such as the main journal of CNS, what they like to accept is this kind of work that can have an impact in multiple fields.

For example, materials such as graphene, which have very high performance and potential and can be used in various fields, are not surprising to be listed in the main journal of CNS.

For example, in the field of organic photovoltaics, the materials developed can only be used by themselves, and it is difficult to expand to other fields. Therefore, it is very difficult to reach the top of the CNS top journal, and it is possible to achieve very breakthrough progress. .

And, having said that, it's not that if you can't get a CNS job, it's not important.

For example, CNS hardly accepts purely theoretical articles, so many theoretical physics research, they pay more attention to the top journal in the field of physics——PRL (PHYSICAL REVIEW LETTERS), the impact factor of this journal is only about 8, but The H factor is as high as 200 or more, that is, the number of articles with more than 200 citations exceeds 200.

There are even some researchers who believe that PRL is stronger than "Nature". They think that what is posted on CNS is the kind of "experimental progress full of gimmicks", and there is no pure theoretical research.

In short, different fields in the scientific research circle have different ways of playing, and there is no set of constant standards.

In addition, after becoming famous, some famous scientists also like to publish their important work, that is, the kind of articles that can be published in the main journal of CNS, in the "garbage" journals founded by their own motherland.

This is not very strange, "Science has no borders, but scientists have a motherland".

After reading the literature, Xu Qiu summed up two major trends in the field of organic photovoltaics:

First, the absolute number of articles has increased. In the past, a dozen articles above the second district may be published, but now more than 20 or 30 articles above the second district may be published in a month, which shows that the popularity of this field has begun to increase. .

Second, the proportion of literature related to non-fullerene receptors has increased. Previously, the proportion of articles on non-fullerene receptor systems may have been less than 30%, but now it is close to 50%. This proportion may become larger in the future. After all, the development of the fullerene system is almost stagnant now, and there is nothing new to study, and there are still many places to be explored in the non-fullerene system, not to mention the device performance. It surpasses the fullerene system in an all-round way.

Behind the formation of these two trends, the ITIC system developed by Xu Qiu has taken a lot of credit.

Xu Qiu checked the ITIC work originally published on AM on the web of science (wos) website. Currently, it has been cited 17 times in real time. It is estimated that when the wos website is updated in the future, this work will be selected as a high-level work. There is a very high chance of being cited or even rated as a hot article.

This article, which became Xu Qiu's second Grand Slam article, was basically a nail in the coffin.

The growth rate of the last PCE11 system article has slowed down a lot, and it is estimated that it can only reach the level of 100 citations at most. Now, Xu Qiu feels that the work of this ITIC system is expected to go even further. Far.

For [non-review] work in [non-biological and medical fields]:

It is good enough for an article to be cited more than 10 times.

Most of the work has 0, 1, or 2 citations, and they may still cite themselves. After all, from the perspective of journals, whether the impact factor can break 10 is a watershed. Journals that break 10 are basically in the first district. Journals, specific to each article, are similar.

And the number of citations of the article has exceeded 100, which can be regarded as a representative work.

Even if CNS and the major sub-journals of "Nature" have an impact factor of only 40, most of the work that can be published on it will not be cited more than a hundred times, because the impact factor is an average value, and some articles with a particularly high number of citations , will drive the rise of the overall impact factor, just like "I and the richest man have an average asset of over 100 million yuan".

If the number of citations of an article can exceed one thousand, it is usually a pioneering work leading a subdivided field, which is rare in various journals.

If an academic worker has published such an article, he can basically blow it up for several years.

Because the difficulty of achieving this achievement is even more difficult than publishing the CNS main publication, and it usually takes a long time to ferment.

For example, the main journal of "Nature" has an H factor of about 360, which also means that since the establishment of "Nature", the number of articles with more than 360 citations has exceeded 360.

So since the publication of "Nature", the number of articles cited more than 1,000 times must be below 360, and the number of articles included in "Nature" in a year is about 2644.

Which is more difficult, at a glance.

Xu Qiu felt that his AM article of the ITIC system, according to the current popularity, would undoubtedly have more than 100 citations.

There is even a slight chance that it can reach the level of a thousand citations.

As for whether we can achieve this goal, it depends on the efforts of our peers.

This is a bit similar to the "sauce-flavored technology" of flower growers. The stock market, funds, hot money, and institutions buy a stock together, and the stock price of this stock will rise steadily.

The same is true in the academic circle. Everyone lifts the sedan chair to each other and stirs up the enthusiasm in a field. The boss can publish more good articles, and other followers can also write a few ordinary articles in the first and second districts.

This is hello, hello, hello, everyone, in the true sense, without side effects, unlike the stock market where leeks will eventually be cut.

If an article with more than a thousand citations is a pioneering work in a subdivided field, then it is basically a pioneering work in a large field if the number of citations exceeds 10,000, and it usually takes a long time to accumulate.

For example, almost twenty years ago, in 1995, F Wudl and AJ Heeger and others pioneered the field of organic photovoltaics, and their work was published in "Science", and the number of citations of that paper is now 7000+.

For this level of work, the number of citations has not exceeded 10,000, and it is conceivable how difficult it is for an article to have more than 10,000 citations.

Finally, there are articles with more than 100,000 citations, but there are only three of them at present, and they are all related to biology.

According to the statistical results of relevant statistical agencies, in the past half a century, most of the most cited works in scientific literature are some important biological laboratory techniques.

Among them, methodological researches such as protein quantification, DNA sequencing, PAGE, and Western blot rank among the top 10. Because of their groundbreaking basic research methods, they have become the reference of research standards in a certain subject area, resulting in a large number of citations.

Biologists tend to cite each other's research more often than in many other fields, resulting in an increasing number of biological laboratory techniques being cited.

The most cited work is a 1951 paper - "Protein measurement with the folin phenol reagent", which describes a method for the determination of protein content in solution, which is now more than 300,000 citations.

In addition, at least 12,000+ citations are required to enter the top 100 citations of a paper.

In other words, over the years, the number of articles with more than 10,000 citations is only one or two hundred.

Of course, it is definitely not objective enough to judge the quality of a work based on the number of citations alone.

On the one hand, older papers have had more time to accumulate citations;

On the other hand, some world-renowned papers, because they are truly fundamental discoveries, quickly become part of textbooks and everyday life, becoming familiar terms that don't need citations.

For example, Einstein's special theory of relativity, the determination of the DNA double helix and the discovery of high-temperature superconductors.

Therefore, modern bibliometricians dislike the traditional method of simply counting citations when measuring the value of a paper.

Instead, they prefer to compare the citation counts of papers of similar age and comparable fields.

This is why the two indicators of high citations and hot articles are now used to judge whether a job is good or bad.
