I Have a Research Support System

Monday, group meeting.

In the first link, Wei Xingsi sent money to several friends who had recently published articles. This time he prepared cash, which had just been taken out of the bank. Stacks of them smelled like ink.

Han Jiaying and Chen Wanqing's EES and AEM were accepted respectively, and each received 3,000 soft sister coins. Xu Qiu's ACSAMI article also received 1,500 soft sister coins.

Speaking of it, ACSAMI receives as many as 5,000+ manuscripts each year, and the impact factor can still remain around 7 or 8. The division of the Chinese Academy of Sciences is even the first division of the major category and the second division of the minor category, which Xu Qiu did not expect. Because he thinks this journal is very easy to post, and if there are any relatively poor jobs in the group, they are all submitted here, which is equivalent to the manuscript recycling bin...

The pass rate is very high, almost every submission must be a hit.

After distributing the bonus, Feifei Wu began to report: Last week, a two-dimensional perovskite device with a diphenylethylamine organic spacer layer was carried out. The efficiency is not high for the time being, only about 6%, and further optimization is needed. This is the XRD characterization result... ...

Wei Xingsi asked casually, Do you have a preliminary guess as to what caused it?

The possible reason is that the number of layers of the two-dimensional perovskite is too small, Wu Feifei explained: My plan is to increase the n value. I set the n value to 4 referring to the n-butylamine and isobutylamine systems. , the current diamine system, the n value of 8 is equivalent to the n value of the monoamine system 4.

Okay, Wei Xingsi nodded, If you have any samples to test for TAS and THz, you can just contact Feng Shengdong in Sweden.

After a pause, Teacher Wei asked again: Sun Wo has finished his graduation project, when will he come over?

Sun Wo...he said that he probably will wait until after the summer vacation. Wu Feifei responded.

Okay, let him come as early as possible. Wei Xingsi knocked on the table, called his name and said, Duan Yun, tell me.

Duan Yun stood up: The work of nickel nanowires has progressed, and the current power factor can achieve...

Well, the result is not bad, Mr. Wei thought for a moment, then decided: Then start to sort out the data, and write the article according to the direction of JMCA...By the way, what about the other thermoelectric system with one- and two-dimensional materials?

That won't work. Duan Yun replied very simply, and shook his head.

Heh. Wei Xingsi chuckled lightly, said nothing, then nodded towards Tian Qing.

Tian Qing understood, sat on the chair and said: I basically finished the review of Chem. Can finalize.

Subsequently, Chen Wanqing mainly talked about a series of characterization data based on the IEIC system last week, and finally made an outlook, that is, the synthesis of the three materials of IEICF, IEICO and IEICS.

Teacher Wei learned that Chen Wanqing's experiment plan had been discussed with Xu Qiu, so he nodded in agreement without asking any further questions.

Xu Qiu usually communicates with Teacher Wei a lot. Whether it is the current experimental progress or the next synthesis idea, they have already reported, so I just talked a few words casually.

His current status in the group is quite detached. Although he doesn't have the name of a small boss, he has the reality of a small boss. Xu Qiu is basically in charge of coordinating the organic field. Now Teacher Wei basically doesn't take the initiative to find Chen Wanqing and Han Jiaying.

Another special person in the group is Wu Feifei. She is a role similar to the head of the research group, or a scientific research assistant. She is responsible for handling some chores related to the research group, so her monthly labor fee is higher than others. Of course, Xu Qiu's labor fee also exceeded the standard, and he was paid according to the doctor's standard when he was an undergraduate.

This is also because there are more and more people in the group. No matter how energetic Mr. Wei is, it is impossible to cover everything. He can only focus on a few key people to manage.

Like some large-scale research groups where academicians are the big bosses, there may be dozens of students in total. It would be good if the big boss can recognize half of the students. They are all academicians in charge of the professors under the Yangtze River and Jieqing. Then the professors under him stared at a few outstanding postdoctoral and doctoral students. As for the other students, they were basically in a free-range state.

Next, Jiaying Han reported the device performance of the newly synthesized H2x, and at the same time planned the synthesis of the H3x, H4x system, and the PBDB-T system.

As for the synthesis route, Wei Xingsi believed in Xu Qiu's vision and didn't ask too much. Instead, he asked, How is the article on the H1x system going? By the way, where is this article going to be submitted? Now the articles in the group are too Many, Mr. Wei can't remember this kind of small article that is not at the level of AM's top journal...

Han Jiaying replied earnestly: I said before that I was going to vote for CM, and it was written according to the ACS format. Now it's about half done.

Very good. Wei Xingsi praised. In fact, as a third-year undergraduate student, her academic achievements are very impressive. Three papers are written, one for ACSAMI, one for JMCA and one for EES. Now she has to submit another A CM, but Xu Qiu's radiance was even stronger, covering her up.

Finally, Wu Shengnan concluded the report: I did a few experiments with Xu Qiu last week and synthesized the ICIN-DM unit and the FN unit. In the two articles at hand, the work on electroluminescent color change has basically been written, and the summary will probably be written. About halfway.

Okay, Wei Xingsi nodded, If you are free this afternoon, you can bring the article over for me to read. Then today's group meeting will end here, Wu Feifei, go and order lunch...

Wei Xingsi paused for a moment, then suddenly asked: Xu Qiu, what do you think of the new postdoctoral fellow's performance in Zhang Jiang's experiments recently?

Xu Qiu scratched his head, feeling a little puzzled in his heart: Teacher Wei, what's the matter? Now that Wu Shengnan is next to me, can I still make a small report in front of her?

After hesitating for two seconds, Xu Qiu chose to answer truthfully: The performance is very good, and the experimental ability is very strong.

At least, he felt that Wu Shengnan's experimental ability was higher than that of Senior Chen Wanqing...

Wei Xingsi let out a hmm, and then said calmly, Let's end the meeting.

On the way back, Xu Qiu pondered Teacher Wei's intentions. Was it because he was afraid that Wu Shengnan would not cooperate with his work after his postgraduate degree, so he chose to support him?

Xu Qiu shook his head. He had read many officialdom novels before, and knew that many of the leaders' words had deep meaning.

However, most of the people below are guessing and making up their minds, and the things they analyze will deviate from their actual ideas by thousands of miles.

Just like the reading comprehension questions in Chinese in high school, I crackled a paragraph of environmental description, and then asked the students to analyze the emotions conveyed in it.

As a result, the works of living writers were included in the exercise book, and a lot of things were written in the standard answers. As a result, the writer said: I didn't think so much at the time...

Similar is the appreciation of ancient poems, analyzing what kind of emotions the ancients conveyed, what worries about the country and time, what farewell at the pavilion, what life miscellaneous feelings...

Anyway, Xu Qiu didn't have the ability to guess the thoughts of the ancients, so that he often could only get 0 or 1 point for the compulsory ancient poetry appreciation question with a score of about 7 on the Chinese test paper.

However, Xu Qiu really guessed it this time, because at that time Wu Shengnan replied to Teacher Wei very reservedly. The original words were Since it is Teacher Wei's arrangement, I accept it, so Teacher Wei mistakenly thought that Wu Shengnan was not very willing. It is only in the organic field that this is what came out at the group meeting.

As everyone knows, Wu Shengnan is eager to work in the organic field, so that he can hold Xu Qiu's thigh tightly.

In the afternoon, Xu Qiu and Han Jiaying went to Zhangjiang to do synthesis, Chen Wanqing hadn't finished the characterization of the IEIC system, and Wu Shengnan asked Mr. Wei to correct the article, so they all stayed in Handan.

After Xu Qiu and his wife arrived at the A501 office in the microelectronics building, they got bored in it for a while, until the average temperature of the room increased by 0.5 degrees Celsius, and then they came out and entered the next-door laboratory.

Continuing with the synthesis experiment.

Han Jiaying will synthesize the H31 and H32 systems today, which are still derivatives of P-BDT-FTAZ. Both structures introduce fluorine atoms into the BDT unit. Among them, H31 is a linear side chain, while H32 is a dendritic The side chains have the same number of carbon atoms, which is also a commonly used side chain regulation method.

The monomer raw materials of unit D and unit A are purchased directly from the photoelectric company in Shencheng, so it is very easy to synthesize, just put in a Stille reaction directly.

This time, Xuemei used a microwave reactor. According to her previous work experience, the polymerization reaction originally required 12-48 hours. If the microwave reactor is used, it only takes 3-6 hours. Improve experimental efficiency.

The microwave reactor had been used by schoolgirls before, and Xu Qiu didn't use it much. He saw the school girl wearing a radiation-proof bellyband and tinkering with the microwave reactor, so he asked curiously: Is there any difference between the product obtained by the microwave reaction and the ordinary reaction?

There is a difference! Han Jiaying said excitedly, her face turned a little red, she had been asking Xu Qiu for advice before, but today it was the other way around, and the school girl was a little excited.

Han Jiaying continued to explain: I have checked the literature, and there is an article that specifically introduces the Stille coupling reaction, using microwave reactors and not using microwave reactors, and the synthesis of products. The results in the literature show that using microwave reactors will induce new The occurrence of side reactions, such as the formation of side chain reaction sites on the D-A main chain. However, because side reactions also occur in normal reactions, and the microwave reaction time is relatively short, the degree of side reactions in microwave reactions is not necessarily higher than normal The reaction must be serious...

That is to say, the microwave reaction may cause unknown changes to the structure of the product. Xu Qiu concluded: It is unknown whether it is good or bad, right?

That's right, Han Jiaying nodded, and said, During the initial exploration period, in order to quickly obtain products, I always use microwaves for reaction. If the performance of the material is better, I plan to use microwaves or not. Try to synthesize all the methods.”
