Chapter 398: Incarnate "mad dog"

When naming materials in the field of organic photovoltaics, if the original name of the material + number appears, it is usually the original author of a certain material, and it is used for the sake of simplicity.
For example, the donor materials of Xuemei H series and J series are rarely named by others.
Of course, it doesn't matter if it really appears, it's just a name.
Even the same material can have different names.
For example, PCE10 is not uniformly named by different research groups. In addition to the common PTB7-TH, there are also a series of names such as PTB7-Th, PTB7-th, PBDTTT, and PBDTTT-E-T.
Therefore, the name is not important, but the molecular structure that the material name refers to.
So, Xu Qiu turned to the first picture and glanced at the molecular structure. His first impression was: "How can this molecule be so similar to the ITIC-Th we developed?"
Because there are seven conjugated fused rings on the D unit of the ITIC main chain, there are two groups of four conjugated rings on the A units on both sides, and there are four side chains, which is very complicated.
So even if Xu Qiu is the developer of ITIC, he has to look at it a few more times to confirm that its molecular structure is based on ITIC and what changes have taken place.
After carefully observing the molecular structure, Xu Qiu found that this ITIC2 is really ITIC-Th, the molecular structure is exactly the same, but the name is different.
Looking at the device efficiency again, I just barely managed to achieve 10%. No wonder only the JMCA was issued, and the efficiency was not up to standard.
Then, Xu Qiu turned to the homepage and glanced at the author and unit.
Good guy, actually an old acquaintance, the Yanhu research team of the University of Hong Kong, Xu Qiu "robbed" their PCE11 before and took an AM.
Now I don't know if the other party came over and hit the structure deliberately or accidentally, and I can't say for this article.
After all, colliding articles is also very common in scientific research circles.
In particular, there are fixed routines in many fields. There are only a few ways to improve the molecular structure. It is very possible for multiple people to think of the same improvement method to cause the molecular structure to repeat.
Therefore, when there are no obvious hot subdivisions in an industry, large research groups usually form a tacit understanding, each researching a subdivision area, and not easily change, so that collisions between large research groups can be avoided to the greatest extent. Lead to duplication of work.
Anyway, as long as it is not deliberately targeted, it is acceptable to hit the article, and each depends on its own ability.
But if you deliberately target it, it will be more disgusting.
For example, we saw you want to write a big article, and guessed the corresponding molecular structure.
Considering that the preparation time for large articles is usually relatively long, and it is normal for half a year or a year, then we can quickly produce an article with the same molecular structure as yours.
Then the performance may not be very good, and the characterization may not be complete. It doesn't matter, just irrigate it directly on the SCI area 3 and 4, and publish it quickly before you submit your big article.
Once this happens, there is really no way you can do it with others, because you can't prove that others have plagiarized your ideas, and it doesn't necessarily mean that you have plagiarized. It is possible that someone happened to happen.
The final result, although it may not necessarily affect the publication of your big article, because in this case, the two works cannot be exactly the same, and your system performance is better, there is still a chance for the article to be published normally, but if the reviewer Using this to attack the novelty of your article is really a pain point and it is difficult to avoid.
Therefore, in the scientific research circle, it is generally unlikely that you will set up too many "enemies" for yourself. At most, you can't communicate with each other forever, and you usually don't do too much.
In case you really annoy people and become a "mad dog", chasing you all the time, the feeling is really hard to describe.
It is worth mentioning that if it is a paper on physics, mathematics, computer science and biology, it can be posted on the arXiv website in advance, so that this situation can be avoided, while papers related to materials science and chemistry are generally not In doing so, at least in the fields of organic photovoltaics and perovskite, Xu Qiu has not seen such a precedent.
arXiv is a non-profit database operated and maintained by Cornell University.
Because it is free, academic researchers can publish their latest research results on the platform before other top conferences or journals are not accepted, on the one hand to expand publicity and increase their influence; on the other hand, to protect their own research Achievements, because regardless of whether the conferences and journals are submitted to the final retrieval, it takes a long time to wait. It is difficult to guarantee that your results will not be plagiarized by others during the period. arXiv can prove the originality of the paper.
This is similar to "occupying the pit". My article has not been officially included, but there have been key developments or the article has been posted. I will first go to arXiv to declare that this idea is the first that I proposed, so that even Others put forward the same idea, as long as the release time is later than me, I can't shake my status as a starter.
In fields such as mathematics and physics that involve modeling and proof, that is, you can directly copy the results of others, arXiv is still of great significance, because the cost of plagiarism is almost zero, just copy it directly.

But for experiments such as materials science, chemistry, and applied disciplines, if you want to plagiarize, you also need to go through all the experimental procedures. The plagiarism will be very difficult. Otherwise, if someone asks you to get the original data, you will definitely not be able to get it. , Then just show the stuff.
On the other hand, if materials science and chemistry can also "occupy the hole", there will definitely be people who will not do anything, and put up all the molecular structures that can be thought of in the field first, indicating that these structures are mine, then directly Messed up...
Xu Qiu handed the JMCA document to Han Jiaying, and said concisely: "The work of Hong Kong University Yanhu collided with our ITIC-Th."
"Oh?" Han Jiaying widened her eyes in surprise, then took a look at the document, and said: "Really, let's just give up this structure. Anyway, we just synthesized the materials before, and there are no other signs. do."
Said this, the school girl even laughed: "I still have the name of foresight, and I didn't make the characterization of this system in advance, otherwise it would be nothing."
Xu Qiu felt a little helpless, and touched the school girl's head: "You really will make excuses for yourself to paddle."
Han Jiaying smiled: "Then what system should I do next, do you have any specific instructions?"
Xu Qiu decided to take a test for the school girl: "Do you have any ideas?"
"Hmm..." Han Jiaying tilted her head and thought for a while, and said: "There are some ideas, first of all, further improvements based on J2, J3, and H22 donor materials."
After a pause, she continued: "I have communicated with the Shenzhen Optoelectronics Company before. The BDT unit used in J2 and other donor materials contains thiophene units with fluorine atoms and alkyl side chains. This thiophene unit requires five It can be synthesized by only one step reaction, and the synthesis is very difficult. I was thinking about replacing the fluorine atom with a chlorine atom, so that the synthesis step can be directly reduced from five steps to one step, and..."
Xu Qiu said: "Moreover, in the field of organic photovoltaics, although chlorine atoms are introduced in most cases, the photoelectric performance of materials will be inferior to that of fluorine atoms, but it will not decrease too much. For example, the photoelectric performance of -4F and -4Cl is It is basically the same. At the same time, it does not rule out the possibility that the photoelectric performance of the introduction of chlorine atoms will surpass that of the fluorine atom system. If the performance of the material does not decrease but rises after the replacement of chlorine atoms, it is equivalent to winning.
"Yes," Han Jiaying responded with a smile: "I plan to reduce the cost of materials and the reduction of synthesis steps as a major highlight. As long as the performance of the material does not decrease significantly, if the performance of the material can be improved, That would be perfect."
"This idea is good, you can try to do it." Xu Qiu nodded in satisfaction. The research direction proposed by the school girl is not too problematic, and the thinking is very clear and feasible.
At the same time, the idea of ​​the school girl was also in the "Hundred Articles" plan that Xu Qiu had thought of before, so he directly advanced its priority in the simulation laboratory so that he could get the results of the exploration earlier.
If this idea is a dead end, you can turn your head back in time.
After all, being suitable in theory does not mean it is suitable in practice.
Just like drawing a card and drawing a blind box, I don’t know whether it will be a golden legend or a trash before drawing. Even if 99% of the SSR will be issued, 1% will be the N, and the black-faced person will still receive N, reverse SSR understanding a bit.
In the same way, if an idea in scientific research is not actually implemented, it is difficult to know what the final result will be, otherwise there will be no saying that "practice is the only criterion for testing truth".
"I have another idea." Han Jiaying raised her small hand.
"Oh? Let's listen." Xu Qiu came with interest.
Han Jiaying continued: "We can directly call the Blue River ~EbookFREE.me~ the device performance data of several non-fullerene system standard samples prepared by the scratch coating method, that is, using glass ITO substrate, metal electrode Evaporation, the method of only scratching the effective layer, is compared with the device prepared by the normal spin coating method."
Xu Qiu put his cheek in one hand, thought for a moment, nodded, and said in a good way: "This idea is indeed possible. I will take the time to talk to Yang Qin and let him help arrange the experiment."
For companies like Blue River, they generally pursue realizable invention patents, and publishing articles is of little significance to them.
Because posting an article means publicizing your invention/discovery free of charge, and you have to spend time and energy to write an article, and even pay a fee for the article layout, which is not only not profitable, but also a loss.
However, these data are of no use to Blue River, they are useful to Xu Qiu and others. They can be used directly to sort out an article, which is considered "waste utilization".
Not only that, the concept of squeegee coating is rarely mentioned by researchers in the current non-fullerene organic photovoltaic field, which is a big bright spot.
If the work is published early, the performance of the device will be better, and it will be another AM grade article.
