I Have a Research Support System

Material one 216, at the desk, everyone exchanged information about the national scholarship.

Wu Feifei raised her head: Just now I received an email from the counselor. I have entered the defense. A total of five of our second-year Ph.D. students have entered the final defense.

Chen Wanqing answered, Wu Feifei, you must be number one.

That's right, Wu Feifei nodded, and explained: Because my article scores are relatively high, with a total of more than 200 points, and the second place is only in the early 100s.

Wu Feifei changed the topic: However, I see that the second place published two first-authored articles on Appl. Surf. Sci. Applied Surface Science. I checked the impact factor of this journal, and it was only 3 a few years ago. Now Slowly rose to around 4 or 5, the major category is engineering technology zone 2, the small category of material science: membrane is zone 1, physics: condensed matter physics and physical chemistry are both zone 3, physics: application is zone 2, and then our materials It is calculated according to one district.

No way, our school counts by sub-category. Chen Wanqing shook her head and said, JMCA, CM, Small, etc. with an impact factor of around 10 are also in the first district, but the fields related to small-category materials are in the second district. , it will be calculated as the second district.

Chen Wanqing continued: I also entered the defense. I ranked second in the class and first in the essay score. There is no way. The grade point is only 3.2, which is a hindrance. A total of seven students from the third and fourth grades entered the defense. Duan Yun took the eighth place...

Duan Yun made a sad face: Don't call me, I want to be quiet...

Wu Feifei turned her head to look at Xu Qiu: You should be the only one in your Boyi defense.

Xu Qiu replied: There are three...

Wu Feifei was surprised: So many? Do you know anyone?

No. Xu Qiu shook his head. When the counselor sent an email, he only showed the student number, without specifying the specific name. Of course, he could check it if he wanted to, but he was lazy.

When I switched to my doctoral degree last year, none of the Ph.D. freshmen at the same level as me entered the defense, Wu Feifei slammed her mouth, It seems that the competition for the National Ph.D. It's over.

Senior Wu Feifei, you must be stable. There are six articles in total, Xu Qiu said.

After all, it's an article I've saved for two years. Wu Feifei explained.

By the way, how many national awards do we have for doctoral students? Xu Qiu asked casually.

Hmm... Wu Feifei thought for a while, and said: It seems that there are nine in total, and then one will go to the Equipment Institute, and the remaining 15 people from the three grades of the Ph. .”

I guess the defense is just a formality, Chen Wanqing added: The time for the defense is only 3 minutes. What can be said may have been pre-determined in advance. The number and grade of the articles are the real thing.

Wu Feifei said, Who knows.

At this time, Tian Qing appeared at the gate of 216, and she was late as usual.

As soon as Tian Qing met, she excitedly said to everyone: Have you received the email, the notification of the scholarship defense.

Wu Feifei took a look at Tian Qing: We are at the same level. I have seen your name on the list. In the master's degree, the grade point is the first, the essay is the first, and the total score is the first.

Yes, yes, Tian Qing said with a chuckle: It seems that you all already know, by the way, how is the situation of your doctoral students this year.

Wu Feifei explained to Tian Qing the result of the discussion just now.

After hearing this, Tian Qing nodded: It seems that the competition for doctoral students this year is quite fierce. A total of three doctoral students in our group have been selected. I wish you all the prizes.

Duan Yun at the table just wanted to plug his ears, I can't hear, I can't hear.

His situation at this time was indeed a bit embarrassing. Sun Wo and Mo Wenlin, who stayed in Handan 216, saw that something was wrong, and they all ran to the inner laboratory to do experiments. Wu Shengnan went to Zhangjiang, and several undergraduates did not come.

Thus, Duan Yun discovered that besides him, five people around him, Xu Qiu, Wu Feifei, Chen Wanqing, and Tian Qing, had all entered the national award defense, and one Han Jiaying had already won the national award...

He is the only one who is unlucky.

After everyone communicated, they returned to the normal rhythm of scientific research.

In the next few days, Xu Qiu continued to write articles, and finally published the semi-transparent AM article on Sunday, and handed it over to other authors to help revise.

He talked to Wei Xingsi, and then put Mo Wenlin in second place, and Wei Xingsi agreed without saying anything.

Because the cooperation with Gong Yuanjiang in the group is now in the honeymoon period, including the few AM articles that Gong Yuanjiang posted later, they all bear the names of Xu Qiu and Wei Xingsi. In this position of Shizuo, none of them have connected to the communication.

For the article in Xu Qiu's hand, he and Mo Wenlin were in the same group, behind them were Chen Wanqing, Wu Shengnan, Han Jiaying and Gong Yuanjiang, and also brought along a new undergraduate Xu Xinjie, because she helped Mo Wenlin complete some experiment.

This work was full of calculations, and it took a total of ten days.

Starting from scratch, it takes ten days to complete an article, and this is an AM-level article, which can be called very fast.

Of course, if you include the experiments done by Mo Wenlin and the time spent in the simulation laboratory in the early stage, it will be about two or three weeks.

However, the repeatability data of the current devices is not enough. Mo Wenlin made about 20 batches of devices before and after the holidays, and there are still more than 10 batches short.

Monday, short group meeting.

Wei Xingsi still did not allow several undergraduates to participate, and planned to investigate them for a while.

Wu Feifei has two undergraduates under her command, and the progress of the experiment is obviously much faster now.

In her system last week, the performance of the device has increased to more than 10%, reaching 10.36%, and after using thermal annealing and solvent annealing, the hysteresis of the device has been significantly improved. Now she is directing undergraduates Help her do experiments while organizing the articles by myself.

For most researchers, without a system, it will be more troublesome when exploring experiments. They need to explore step by step, starting from doing nothing, and then gradually trying various optimization methods.

It's not like Xu Qiu can directly get the best conditions and save a lot of time.

Duan Yun continues to sort out the work of cobalt nanowire doped PVDF matrix thermoelectric materials, and the progress is about 80%.

During this period of time, Duan Yun paddled a lot, and the progress of the article only advanced by 20 to 30% in a week, but Wei Xingsi didn't seem to want to control him.

Sun Wo assigned half of his younger brother Yu Ya from Wu Feifei to help him prepare a two-dimensional perovskite standard system based on phenylethylamine and n-butylamine organic spacer layers.

As a result, Yu Ya made two batches of devices, and the efficiency of the devices actually broke through, from a little more than 8% to 9.37%...

When Sun Wo saw the result, he said directly, Meow meow???

When reporting, Sun Wo was most afraid of Wei Xingsi asking: Did you make this device yourself?

Fortunately, Teacher Wei didn't do that, and encouraged him to say good job.

However, why does it sound so heart-wrenching...

In addition to the device results, Sun Wo took two sets of electron microscopes SEM and AFM, and found some morphological evidence to support the conclusions obtained from TEM.

In fact, if Sun Wo’s system focuses on morphology, as long as the device efficiency can be said, the difference between 8% and 9% is not big, but he still accepts that he can’t compare with an undergraduate student who has just joined the group. .

But when he thought about Xu Qiu and Han Jiaying, Sun Wo felt relieved immediately. The undergraduates of Shanghai Comprehensive University had to give in.

Tian Qing continued to sort out the exciton binding energy and exciton diffusion distance data of several donor and acceptor materials, and drew some cartoon illustrations to explain the conclusions she obtained from the experimental results. The article plans to be submitted to ACSEL.

Chen Wanqing went to Blue River this Saturday, and made another batch of translucent, flexible, colorful, scrape-coated, and full-solution processed devices. The performance of the devices has improved slightly, but it still hasn't broken through to 7% or 8%.

The main problem now is the uneven thickness of the film obtained by scraping. It is necessary to further solve the stability of scraping. She is also discussing with the people at Blue River how to solve this problem.

On the other hand, the senior sister's IEICO-4Cl article has already been submitted, and now she only goes to Blue River once a week, and there is no work at hand for the time being. The rest of the time, the senior sister continues to write her graduation thesis.

Similar to Xu Qiu's previous undergraduate thesis, there are ready-made SCI articles. It is very simple to write a graduation thesis. You only need to translate without thinking, and then make changes, and set a template with a prescribed format.

Xu Qiu reported on the next work plan:

The short-term task is to give priority to writing the review of Joule, because it only involves less than 20 related documents published by the group, so this review does not need to be written too long, and it will not consume too much time...

Mid-term task, complete two tasks, one is the job of the scraping and coating standard sample system proposed by the school girl, and the other is the work assigned to the school sister before...

The long-term task, that is, the two projects Mr. Wei plans to apply for, the main direction of the outstanding youth project and the key project, is to prepare stacked devices and introduce nitrogen atoms into the ITIC series molecules...

Han Jiaying reported the results of her discussion with Xu Qiu, that is, the synthesis of derivatives in which the fluorine atoms in H22, J2, and J3 were replaced by chlorine atoms, which can be regarded as returning to the main business.

Wu Shengnan started writing IDIC-M articles. This is another job with an efficiency of 13%. It is not a big problem to vote for AM. After all, it is the only system that can break the 13% efficiency at this stage.

This is the advantage of staying ahead in a certain field, and it is relatively easy to publish articles.

Similar to the beautiful country, after forming a pattern of one superpower and many powers, even if it does not take the initiative to develop, inertia will push it to run ahead of other countries.

Of course, if you keep relying on your laurels, you will be slowly overtaken by other countries.

For example, in recent years, flower growers have quietly risen.

Mo Wenlin H22: ITIC: The article on the IEICO system has been written.

Originally, the target journal was AM, but later she planned to vote for AEM for the first time, because her writing speed was a bit slow.

Now there are several articles on the non-fullerene ternary system that follow the trend. If she submits this work to AM, there is a high probability that it will be rejected.

It’s better to be more pragmatic, submitting directly from AEM, the probability of passing the manuscript will be higher.

PS: There are only two updates today. During the Chinese New Year, it is too busy. It is difficult to guarantee two updates of 6,000 words+ a day. After a year, there will be a burst of updates.

PS2: Please fill in the associated words in the brackets: () I have not exploded, () I want votes.
