Chapter 300: Teacher Wei, where is the trouble?

"I have a scientific research support system novel ( to find the latest chapter!
On Monday, the group meeting.
In the first link, Wei Xingsi sent money to several friends who published articles recently. This time he prepared cash. He just took it out of the bank, piles of piles, exuding the smell of ink.
Han Jiaying and Chen Wanqing's EES and AEM were accepted respectively, and each received 3000 soft sister coins, and Xu Qiu's ACSAMI article also received 1500 soft sister coins.
Speaking of which, ACSAMI receives as much as 5000+ manuscripts each year, and the impact factor can still be maintained at around 7 and 8. The Chinese Academy of Sciences is even divided into the first category and the second category, which Xu Qiu did not expect. Because he felt that this journal was easy to publish, and any relatively poor work in the group was finally posted here, which is equivalent to a manuscript recycling station...
The passing rate is very high, almost every submission must be hit.
After the bonus was issued, Feifei Wu began to report:
Last week, the two-dimensional perovskite device with the organic spacer of diphenylethylamine was performed. The efficiency is temporarily not high, only about 6%, and further optimization is needed. This is the result of XRD characterization... …"
Wei Xingsi asked casually: "Are there any preliminary guesses and what caused it?"
"The possible reason is that the number of layers of the 2D perovskite is too small," Wu Feifei explained: "My plan is to increase the value of n. Before referring to the system of n-butylamine and isobutylamine, set the value of n to 4. In 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 directly contact Swedish Feng Shengdong."
After a pause, Teacher Wei asked again: "Sun Wo has finished his graduation project, when will he come?"
"Sun Wo... he said he would have to wait until after the summer vacation." Wu Feifei responded.
"All right, let him come as soon as possible." Wei Xingsi knocked on the table and said by name: "Duan Yun, you can speak."
Duan Yun got up: "The work of nickel nanowires has progressed, and the current power factor can be achieved..."
"Well, this result is not bad," Teacher Wei thought for a moment, and then said: "Then start to organize the data, and write the article in the direction of JMCA... By the way, what about the thermoelectric system that adds one or two-dimensional materials?"
"That won't work." Duan Yun replied simply and shook his head.
"Heh." Wei Xingsi chuckled lightly, without saying a word, and then made an effort towards Tian Qing.
Tian Qing understood, sitting in a chair and said, "I have basically written the review of Chem.Soc.Rev., and it has now been passed to Lund University in Sweden, letting Feng Shengdong and Professor T?nu help to revise it. This week It should be finalized."
Subsequently, Chen Wanqing mainly talked about her series of characterization data based on the IEIC system last week, and finally made a vision, that is, the synthesis of IEICF and IEICS three materials.
Teacher Wei learned that Chen Wanqing's experimental plan had been discussed with Xu Qiu, so he didn't ask more, and directly nodded in agreement.
Xu Qiu usually had a lot of exchanges with Teacher Wei. Both the current experimental progress and the following synthesis ideas have been reported, so I just said a few words at random.
His position in the group is relatively detached now. Although he does not have the name of a small boss, he has the reality of a small boss. Xu Qiu is basically responsible for the organic field. Now Teacher Wei basically does not take the initiative to find Chen Wanqing and Han Jiaying.
Another special person in the group is Feifei Wu. She is similar to the role of the research team manager, or research assistant, who is responsible for handling some chores related to the research team, so her monthly labor fees are a little more than others. Of course, Xu Qiu's labor fees are also above the standard, and will be paid according to the doctoral standard during the undergraduate period.
This is also because there are more and more people in the group. No matter how energetic Teacher Wei is, it is impossible to cover everything. He can only manage a few key people.
Like some large-scale research groups with academicians as big bosses, there may be dozens of students in total. It would be good for big bosses to recognize half of the students. They are all professors under the supervision of "Changjiang" and "Jieqing". Then the professors under his staff stared at a few outstanding postdoctoral and doctoral students. As for the other students, they were basically in a free range.
Next, Han Jiaying reported on the device performance of the newly synthesized H2x, and planned the subsequent H3x and H4x systems, as well as the synthesis of the PBDB-T system.
As for the synthesis route, Wei Xingsi believed in Xu Qiu’s vision and did not ask too much. Instead, he asked: "How is the article written in the H1x system? By the way, where is this article going to be contributed?" Many, for this kind of non-AM top issue, Mr. Wei can't remember a little...
Han Jiaying replied earnestly: "I said before that I was going to vote for CM, and I wrote it in ACS format. Now it's about half completed."
"Very good." Wei Xingsi complimented. In fact, as a junior undergraduate, her academic achievements are very eye-catching. There are three articles, one for ACSAMI, one for JMCA and one for EES. Now she wants to vote again. A CM, it's just that Xu Qiu's light is even worse, covering her.
Finally, Wu Shengnan finished his report: "Last week I did a few experiments with Xu Qiu and synthesized the ICIN-DM unit and the FN unit. The two articles in hand have basically written the work of electroluminescence. About half of it."
"Okay," Wei Xingsi nodded, "If you are free in the afternoon, you can bring the article over and let me have a look. Then that's it for today's group meeting, Wu Feifei, you go order lunch..."
Wei Xingsi paused, and then asked, "Xu Qiu, how do you think the new postdoctoral queen has performed in Zhang Jiang's experiment recently?"
Xu Qiu scratched his head, feeling a little puzzled in his heart: "Ms. Wei, who is this trouble? Now 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, the experiment ability is very strong."
At least, he feels that Wu Shengnan's experimental ability is higher than that of Chen Wanqing...
Wei Xingsi let out an "um", then said lightly: "Let's end the meeting."
On the way back, Xu Qiu wondered what Teacher Wei's intentions were. Is it because he was afraid that Wu Shengnan's post-doctorate would not cooperate with his work, so he chose to help him support the field?
Xu Qiu shook his head. He had read a lot of officialdom novels before and knew that many of what the leader said had no meaning.
However, the people below spend most of their time guessing and brain supplementing, and the things they analyze will deviate from their actual ideas.
It's like a Chinese reading comprehension topic in high school, crackling an environmental description, and then let the students analyze the emotions conveyed in it.
As a result, the works of some surviving 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..."
Similarly, there is the appreciation of ancient poems, analyzing what kind of emotion the ancients conveyed, what worry about the country, what long pavilion to send off, what life miscellaneous feelings...
Anyway, Xu Qiu didn't have the ability to guess the thoughts of the ancients, so that on the Chinese examination paper, which is about 7 points in the compulsory examination of ancient poetry, he often only got 0 or 1 point.
However, Xu Qiu really got it right this time, because at that time Wu Shengnan was very reserved in replying to Teacher Wei. The original words were "Since it was Teacher Wei's arrangement, I accept", so Teacher Wei mistakenly thought that Wu Shengnan was not very willing. To do the organic field, this is the result of the group meeting.
As everyone knows, Wu Shengnan is eager to go into the organic field, so that he can hold Xu Qiu's thigh firmly.
In the afternoon, Xu Qiu and Han Jiaying went to Zhangjiang to do the synthesis. Chen Wanqing had not finished the characterization of the IEIC system. Wu Shengnan asked Teacher Wei to change the article, so they both stayed in Handan.
After Xu Qiu and the two arrived at the A501 office of the Microelectronics Building, they were tired of it for a while, until the average temperature of the room increased by 0.5 degrees Celsius, and they came out of the inside and entered the next laboratory.
Continue the synthesis experiment.
Han Jiaying is going to synthesize H31 and H32 systems today, which are still derivatives of P-BDT-FTAZ. Both structures have introduced fluorine atoms in the BDT unit. Among them, H31 is a linear side chain, and H32 is a dendritic With the same number of carbon atoms in the side chain, this is also a commonly used side chain control method.
The monomer raw materials for the D unit and A unit are directly purchased from Shenzhen Optoelectronics Company, so it is very easy to synthesize, just throw a Stille reaction directly.
This time, the school girl used a microwave reactor. According to her previous work experience, the polymerization reaction originally took 12-48 hours. If the microwave reactor is used, it only takes 3-6 hours. Improve experiment efficiency.
The microwave reactor had been used by school girls before, but Xu Qiu didn't use it much. He saw the school girl wearing a radiation-proof bellyband and tinkering with the microwave reactor, and asked curiously: "Will the product obtained by the microwave reaction be different from the ordinary reaction?"
"There is a difference!" Han Jiaying said excitedly~EbookFREE.me~ Her face was a little reddened. She had been asking Xu Qiu for advice before, but today it is the other way around. The school girl is 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 a microwave reactor and not using a microwave reactor, and the result of the synthesis. The results in the literature show that the use of a microwave reactor will induce new For example, side chain reaction sites are formed on the main chain of DA. However, because the normal reaction also has side reactions, and the microwave reaction time is relatively short, the degree of the side reaction of the microwave reaction is not necessarily better than the normal The reaction must be serious..."
"In other words, the microwave reaction may cause unknown changes in the structure of the product." Xu Qiu concluded: "Good or bad is unknown, right."
"Yes," Han Jiaying nodded and said: "During the preliminary exploration, in order to get the product quickly, I use microwave reaction directly. After that, if the performance of the material is better, I plan to use microwave and not use microwave. Try to synthesize all the methods."
