Chapter 378: Welcome to the second Grand Slam

On the following Thursday and Friday two days, Wei Xingsi published five top-ranking articles in a row.
Among them, there are four AM articles, including Feifei Wu's two-dimensional perovskite review, Xu Qiu's IDIC system, Chen Wanqing's -4F system, Wu Shengnan's six-in-one system, and an EES article, Han Jiaying's J2 system.
Obviously, it is impossible to get all the five top-level articles. After all, colleagues will love each other and kill each other. Xu Qiu estimated that two or three articles would be good.
Of course, none of them are impossible.
The reason is also very simple. For example, Xu Qiu voted for a job that has both the highlights of "12% high efficiency" and the highlights of "new materials and new perspectives". As a result, the AM vote was rejected. Journals like ACSAMI and AELM have gone up.
If an article is like this, it's fine. If it is like this for five consecutive articles, a concept similar to the "precedent" in law will be formed, that is to say, a reference is formed. Then other similar work submitted by colleagues, If even Xu Qiu's work is not as good as Xu Qiu's work, why would he be embarrassed to vote for articles with higher grades than ACSAMI and AELM? Maybe he went straight to the three districts.
Therefore, in a sense, peer review is also limited. You cannot target it as you like and give negative reviews, which will lead to the collapse of the entire field.
What's more, not all scientific researchers will deliberately cause trouble, and many people still focus on academics.
On Friday afternoon, Wei Xingsi appeared at the door of 216 and happily said: "Xu Qiu, just received an email from the AM editor. The article you voted for in the ITIC system before was again selected as the cover article. It will be published directly in the next issue. The speed of this article is really fast. I remember the electronic version has only been online for about a month..."
For popular journals such as AM, after a normal article is included in the electronic version, it usually takes a few months or even more than half a year to line up before it can be officially published. Xu Qiu’s current article only took more than a month. It will be officially published in time, which can be said to be the speed of light. There is a high probability that the editor-in-chief sees this work and thinks it has great potential, so he personally shot it and advanced the round.
Similar to novel websites, which have chief editors and general editors, journal companies also have chief editors and general editors. The editors have very large authority, and they are usually veterans who have been in this industry for more than ten years, and they control academic papers accurately.
In other words, if the editor-in-chief does not engage in research, he cannot do brilliant research work, but the ability to judge a job is basically MAX.
"What about the cover?" Xu Qiu asked.
"Hmm..." Wei Xingsi turned his head and said, "Tian Qing, give it to you this time?"
"Yes." Tian Qing nodded in response.
"That's OK, get it done by next Monday." After Wei Xingsi finished speaking, he handed Xu Qiu a dozen documents: "This is the recent organic photovoltaic literature. Recently, many ITIC have followed suit."
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, "If you are composing the picture, you can refer to the style of our previous cover article, or refer to the cover of other people on the journal website. I only make a request, showing that ITIC is a flat, non-rich Leene receptors are different from traditional PCBM materials."
Tian Qing nodded and said: "No problem, I have had the first experience, now it will be a lot easier to do the cover for the second time."
After finishing the cover, Xu Qiu briefly flipped through recent documents. There were more than a dozen articles.
These are all articles published by Wei Xingsi's research group, all of which are articles from other research groups.
Xu Zhenghong and their IDTBR system did not have a big voice for the time being. They only posted a JMCA, the main structure is still IDTBR, there is not much innovation, I don't know if they are holding a big move or are misfired.
The number of articles related to ITIC work has obviously increased, with a total of five articles.
Most of them use ITIC receptors to follow suit, and then find a donor material that Xu Qiu has not used before, including PPBDTBT, etc., and get 7%-9% efficiency respectively. There is not much novelty, such as structural changes. No sex, or any new ideas.
Therefore, the quality of the article is average relative to AM. The best one was posted on AFM in one area, and three others were posted on JMCA, ACSAMI and CM.
Xu Qiu could do these systems before, but they didn't do it. The purpose was to leave the soup for others to drink. He couldn't break the 10% system, and he couldn't see it anymore.
Among these four articles, Xu Qiu saw three of them once before, and they were all manuscripts reviewed by him. Of course, the specific review tasks were assigned to school girls in the name of "training review skills". With Mo Wenlin and Wu Shengnan, he was responsible for the second review.
The fifth ITIC-related article was posted on AM. It is also the only top-issue article in this batch of documents. It is the work of Gong Yuanjiang's research group.
They used the ITIC receptor in the field of all-small-molecule organic photovoltaics, that is, the donor and acceptor materials are small molecules, and the efficiency directly exceeded 10%, reaching 10.23%, breaking the world record for all-small-molecule systems.
This is the "benefits" of conducting multiple research directions in a research group. Once there is a hot spot, you can just use the existing system in the group to cover it. If it works, you can publish a good article.
A bit similar to the results of interdisciplinary studies, an achievement can be simultaneously applied in multiple fields.
In fact, for CNS main journals, 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 even to be listed in the CNS main journal.
In the field of organic photovoltaics, the materials developed can basically only be played with by yourself, and it is difficult to expand into other fields. Then it is very difficult to reach the top issue of CNS, and it is possible to make very breakthrough progress. .
And, having said that, it's not that it's not important that you can't get a job in CNS.
For example, CNS hardly accepts purely theoretical articles, so many who do theoretical physics research, they pay more attention to the top journal in the field of physics—PRL (PHYSICAL REVIEWLETTERS). The impact factor of this journal is only about 8, but the H factor Up to 200 or more, that is, the number of articles with more than 200 citations exceeds 200.
There are even some researchers who think that PRL is stronger than Nature. They think that what is posted on CNS is the kind of "gimmicky experimental progress", and there is no pure theoretical research.
In short, different fields of scientific research have different ways of playing, and there is no set of constant standards.
In addition, some famous scientists, after becoming famous, also like to publish their important work, that is, the kind of articles that can be published in the CNS main journal, in the "junk" journals established by their home countries.
This is not surprising, "Science knows no borders, but scientists have a motherland."
After reading the literature, Xu Qiu summarized two major trends in the current organic photovoltaic field:
First, the absolute number of articles has increased. Previously, a dozen or more articles in the second area may have been published, but now there may be more than 20 or 30 articles in the second area or more in a month, which indicates 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 be less than 30%. Now it is close to 50%. This proportion may become larger and larger in the future. After all, the development of fullerene systems has almost stagnated, and there is nothing new to study. There are still many places to be explored for non-fullerene systems, not to mention that in terms of device performance, non-fullerene systems are already It completely surpasses the fullerene system.
Behind the formation of these two trends, the ITIC system developed by Xu Qiu took a lot of credit.
Xu Qiu checked the ITIC work originally published on AM on the webofscience (wos) website. At present, the number of real-time citations has been 17 times. It is estimated that when the wos website is updated later, this work will be selected as highly cited. , And even have a great chance of being rated as a hot article.
This article, which became Xu Qiu's second Grand Slam article, was basically ironclad.
In the previous PCE11 system article, the growth rate of the number of citations has slowed down a lot, and it is estimated that it can only reach the level of one hundred citations at most, and Xu Qiu feels that the work of this ITIC system is expected to go further. far.
For [non-review] work in [non-biological, medical fields]:
It’s pretty good that an article can be cited more than 10 times.
Most of the work is 0, 1, or 2 citations, and you may still cite yourself. 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 same area. Journals, specific to an article, are similar.
The article has been cited more than 100 times, and it can be considered a representative work.
Even if the CNS and "Nature" major journals have an impact factor of less than 40, most of the work that can be published on it will not be cited more than a hundred, because the impact factor is an average value, and some articles have a particularly high number of citations. , Will increase the overall impact factor, just like "I and the richest man have more than 100 million assets per capita".
If the number of citations of an article can exceed a thousand, it is usually a pioneering work in a subdivision field, which is rare in various journals.
If an academic worker publishes such an article, it can basically be known for several years.
Because the difficulty of achieving this achievement is even more difficult than publishing the CNS main journal, and it usually takes a long time to ferment.
For example, in the main journal of Nature, the H factor is about 360, which means that since the founding of the journal, the number of articles cited by more than 360 has exceeded 360.
So the number of citations of articles over a thousand since the founding of "Nature" must be less than 360, and "Nature" contains about 2,644 articles a year.
Which is more difficult is clear at a glance.
Xu Qiu feels that according to the current popularity of his AM article on the ITIC system, there is no doubt that the number of citations has exceeded 100.
There is even a probability of losing it, reaching the level of a thousand citations.
As to whether this goal can be achieved in the end, it depends on the failure of colleagues.
This is a bit similar to the "sauce-flavored technology" of the flower planters. The stock market, funds, hot money, and institutions buy a stock in a group, and the stock price will rise steadily.
The same is true in the academic circle. Everyone carries each other's sedan chairs and stirs up the enthusiasm of a field. The big guys can post more good articles, and other people who follow the trend can also get a few ordinary 1st and 2nd district articles.
This is hello in the true sense. Hello, everyone. There are no side effects, unlike the stock market that will eventually cut leeks.
If an article that has broken thousands is the pioneering work in a subdivision field, then the number of citations can exceed 10,000, which is basically a pioneering work in a large field, and it usually takes a long time to accumulate.
For example, almost twenty years ago, in 1995, FWudl and AJ Heeger and others pioneered the field of organic photovoltaics, and their work was published in Science. The paper is currently cited 7000+.
For this level of work, the number of citations has not exceeded 10,000, and the difficulty of the number of citations of the article can be imagined.
Finally, there are articles with more than 100,000 citations, but there are only three articles, all of which are related to biology.
According to the statistical results of relevant statistical agencies, most of the most cited work in scientific literature over the past half century has been some important biological laboratory technology.
Among them, protein quantification, DNA sequencing, PAGE, Westernblot and other methodological research ranks in the top 10. Because of their pioneering basic research methods, they have become a reference for research standards in certain disciplines~EbookFREE.me~ Lots of citations.
Compared with many other fields, biologists tend to cite more of each other's research results, which makes more and more biological laboratory techniques be cited.
The most cited work is a paper in 1951-"Proteinmeasurementwiththefolinphenolreagent", which describes a method for determining the protein content in a solution, which has now been cited more than 300,000 times.
In addition, to enter the top 100 cited papers, at least + citations are required.
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 certainly not objective enough to judge the quality of a job just by the number of citations.
On the one hand, earlier papers have more time to accumulate citations;
On the other hand, some world-famous papers, because they are truly fundamental discoveries, quickly become part of textbooks and daily life, and become familiar terms that people do not need to quote.
For example, Einstein's special theory of relativity, the determination of DNA double helix and the discovery of high-temperature superconductors.
Therefore, when measuring the value of a paper, modern bibliometrics do not like the traditional method of simply counting citations.
Instead, they prefer to compare the number of citations in papers of similar age and comparable fields.
This is also the reason why two indicators of highly cited and hot articles are now used to judge the quality of a job.
