Chapter 402: First exclude 1 correct answer

After finishing the template for "Joule", Xu Qiu started writing articles.
This manuscript article is said to be a review, but strictly speaking, the format is "Perspective", which is literally translated as "Viewpoint", focusing on proposing opinions and prospecting.
Unlike the previous non-fullerene "Review" article written by Xu Qiu, "Review" is literally translated as "review, comment", focusing on summarizing the work done by the predecessors, making a high-level generalization, summary and refinement.
It is also true that at this stage an "view" is more meaningful than a "review, comment".
Because it is now in the embryonic stage of ITIC-type non-fullerene subdivisions, there are not many scientific research results. It is necessary for a pioneer to stand up and guide colleagues on the road ahead, rather than simply sum up the past work.
The forerunner is naturally Xu Qiu, and he deserves it.
At this stage, it can be said that no one understands ITIC better than Xu Qiu, he really understands Wang.
Of course, in actual writing, the content of the two formats of "Viewpoint" and "Summary and Comment" actually have a lot of overlap.
For example, the "Viewpoint" article must also summarize the previous work. Otherwise, it is necessary to talk about the past work, and only talk about the outlook. It is obviously not appropriate, just like a castle in the sky.
Therefore, Xu Qiu intends to write a "view" article according to the idea of ​​"summary and comment" in the previous review, first summarize, and then look forward to a wave.
When the time comes, it is enough to write the contents of the outlook more abundantly, and give your colleagues a good guide.
On the one hand, Xu Qiu intends to write the summary in a parallel format.
The first is the origin of ITIC, that is, how to develop from the IDT-ICIN molecule of the sister to ITIC.
It is necessary to describe the mental process, but Xu Qiu does not have a corresponding mental process, so he plans to compile one now.
In fact, many times there is no reason to do scientific research. It is just that I suddenly thought of an idea, and then tried it. The result was successful and an article was handed.
Scientific research, whether it is a change in material properties or a certain physical or chemical law, is an objective fact, and people's subjective ideas are not important.
But who makes people just want to listen to the story, even if it is a "after-effect", they still have to make up one.
The next few items are:
Improving the D unit of ADA non-fullerene molecules such as ITIC, including changing the conjugate length of the D unit FNIC, changing the IDIC of the D unit side chain, etc., mainly due to the work of Xu Qiu and Wu Shengnan;
Improvements to Unit A, including IT-4F, IT-DM, etc., are mainly Xu Qiu's work;
The molecular structure from ADA to AπDπA, including the system, is mainly Chen Wanqing's work;
The synthesis of wide band gap and medium band gap donor materials, from FTAZ to H22 to H43, from PBDB-T to J1 to J2, is mainly the work of Han Jiaying;
The ternary blend system is mainly Mo Wenlin's work.
The whole small molecule system is mainly the work of Gong Yuanjiang.
In addition, there are fragmentary work published by other research groups. Xu Qiu will also include them in the review article when that time comes, but will not go into too much detail.
On the other hand, Xu Qiu intends to write according to the previous "Hundred Articles" plan.
That is, to list the three improvement paths of donors, acceptors and devices to accelerate the development of this industry.
Among them, translucent, laminated, and the introduction of nitrogen atoms into the ITIC series of molecules are the research Xu Qiu intends to conduct at present and in the near future. It is necessary to consider whether to write it in the review article.
After thinking for a moment, Xu Qiu decided:
Translucent can be mentioned, because this field is of the nature of playing tickets, similar to the previous PDI system, Xu Qiu does not intend to do too deep, so tell others that it’s okay to give them some articles, anyway, he can drink the soup. Great.
Laminate can also be mentioned, because the threshold for preparing laminated devices is relatively high, and it is an open idea. Basically, the peers can also think of it, but there are very few that have the strength to make it. Even if this idea is spoken out, I am not afraid of others. do.
Finally, Xu Qiu does not plan to include the idea of ​​introducing nitrogen atoms in the key project application, because once this idea is included, it may soon be given priority by other research groups.
After all, if a large group of dozens of people is fully fired, the combat effectiveness is still relatively strong.
In fact, now Xu Qiu has put 50% of the "computing power" in the simulation laboratory III on the introduction of nitrogen units, and designed a series of molecular structures, but the difficulty of synthesis is still high and the progress is slow. Did not get very good materials.
However, this kind of thing is really not anxious, just take it slow.
At noon on Tuesday, 11:40.
Xu Qiu, Wu Feifei, and Chen Wanqing had lunch in advance, and came to Caier 401 together, intending to participate in the national scholarship defense.
When they arrived, there were already many students here.
After all, it’s a national award defense. Everyone is very active. If you are disqualified because you are late for the defense, it would be a tragedy.
The person in charge of the on-site guidance is a teacher from the Department of Materials, a tall and thin man with glasses, about 30 years old.
Xu Qiu had only met him a few times and was not very familiar with him. He only knew that this teacher should not be a teaching post, but a civilian post.
Xu Qiu asked the two senior sisters next to him. Chen Wanqing shook her head, and Wu Feifei said: "This is Teacher Gao Xiang, an educational clerk in the Department of Materials, and I will meet him occasionally when going through the procedures and ask him to stamp the official seal of the Department of Materials. ."
Seeing that the number of students at door 401 became more and more crowded, the corridor was almost blocked. Gao Xiang went to the concierge to get the key, opened the door of the next meeting room 402, and arranged for the students to enter and wait.
After Xu Qiu signed in at Teacher Gao Xiang's side and copied the PPT, she and the two senior sisters found a place to sit down, and then scanned the other people on the scene.
Now there are more than a dozen classmates, but apart from the two seniors in the group, he doesn't know any of the others, but Wu Feifei and Chen Wanqing occasionally waved and greeted acquaintances.
Earlier, I received a notice from the counselor, Bao Wei, that there is a direct PhD student and a master PhD student at the same level as Xu Qiu.
Xu Qiu certainly didn't know the postgraduate and PhD student. During the class meeting, he spent most of his time writing articles on "Nature·Energy", and he didn't listen to other people at all.
He also has no plans to meet new classmates, because it doesn't make much sense, and most doctoral students in the same class will not have any intersection.
However, Xu Qiu, the direct Ph.D student, would definitely be able to recognize it, because there were five direct Ph.D students, and he had all met except for himself.
He suddenly became a little curious, who would be his other direct PhD student?
First of all, excluding Mu Xue, who has had a relationship before, she is a direct Ph.D student from Qingbei University, and it will not be her.
Secondly, exclude roommate Sun Yifan. I talked to him before. Sun Yifan only has half a Small article. Such academic achievements will definitely not be eligible for the National Award.
Xu Qiu is not very familiar with the other two cheap roommates.
And I have never heard of a classmate who is very good in scientific research in the same class. Is it possible that this person is more low-key than me?
But anyway, with the method of exclusion, the person who enters the country to defend can only be one of them.
While Xu Qiu was analyzing secretly, he suddenly heard the voice of a slightly familiar girl: "Hello, Xu Qiu~"
He looked up, and it was Mu Xue.
"Hello." Xu Qiu nodded and responded.
He was slightly surprised. This girl has something to do. Undergraduates from Qingbei University went to the Magic City University for direct postgraduate studies, and ended up being admitted to the Freshman National Award defense.
Mu Xue was not very surprised to see Xu Qiu. She is the monitor of the doctoral class, and she knows every doctoral student specifically, and after receiving the email from the instructor, she immediately checked the corresponding student number. Information, naturally know that Xu Qiu was selected to defend.
Originally, after signing in, Mu Xue wanted to sit next to Xu Qiu and have a few words, but she was actually quite curious that there was another direct student who entered the national award defense.
Although it is difficult to defend the National Award for Master and PhD students, there is still a great opportunity. However, direct PhD students and PhD students can also enter the defense. They are basically big-time figures, and there is always nothing wrong with getting to know them.
And Mu Xue knew that she was able to defend the country award, but it was not entirely due to her level of scientific research.
However, when Mu Xue saw Wu Feifei and Chen Wanqing sitting on both sides of Xu Qiu, he did not walk over, but found a corner to sit down.
At 11:50, all the people who were selected for the defense of the National Award for PhD students arrived, and Teacher Gao Xiang began to organize a lottery.
Xu Qiu and the three returned to their seats after drawing lots, communicating with each other.
"I'm No. 1," Chen Wanqing sighed softly, "Hey...I was the first one to play, so what should I do if I am a little nervous?"
"Don't worry, there are only three minutes in total. You just need to talk about two main tasks, and then list the academic achievements." Wu Feifei comforted: "Besides, isn't Mr. Wei sitting below... "
Chen Wan said weakly: "It's okay if you don't mention him, what should I do when I mention him at www.uukanshu.com."
"Um..." Feifei Wu thought for a while, and said: "I teach you a method. You imagine the teachers below as wooden stakes, and then let go of yourself..."
"Will this really work?" Chen Wanqing was suspicious: "Well, I will try."
Xu Qiu can understand the situation where Senior Sister is not nervous when speaking in front of ordinary acquaintances, and when she is nervous in front of strangers, but he can't help much, because to solve such problems, we can only rely on more practice. There is no shortcut. .
Wu Feifei continued: "I'm No. 6, in the middle position. Well, as long as Xu Qiu is not No. 5... What's your number, Xu Qiu?"
Xu Qiu responded: "No. 14, the second to last."
"That's good," Wu Feifei nodded, and then turned around: "It's No. 15. It's a bit miserable. It's behind Xu Qiu."
