I Have a Research Support System

During the break after dinner, Xu Qiu made a voice call to Han Jiaying.

The two talked about you and me for a while, and Xu Qiuyin vaguely heard the senior sister's voice %￥#狗@*\u0026, so he turned the topic to business:

Today I made a batch of devices, and all the tests have been completed in the afternoon.

Hmm... Han Jiaying asked expectantly, Then how efficient is my device?

Guess. Xu Qiu chuckled.

Bad brother, Han Jiaying snorted, uncertain, it should be more than 1%...

Congratulations, you guessed right, the highest... Xu Qiu paused for a while, 4.4%!

Wow, that's so high! Han Jiaying shouted excitedly, and immediately realized, Didn't you just let me guess, why don't you just tell me.

It's a reward for guessing right. Xu Qiu said casually.

Okay, Han Jiaying didn't get too tangled, and asked, Then I will follow your path to make the second-generation 3D-PDI and carry out condensed rings? Xu Qiu only took her two products yesterday. 15 mg, and more than 30 mg remained in Zhangjiang.

Well, the previous TRPL results show that fused rings will improve the efficiency of exciton splitting, which is beneficial to improve device performance. It may be a general modification method for 3D-PDI series, but not all systems can be fused rings. of……

Han Jiaying interjected: In my system, the external thiophene ring can also form a condensed ring structure with the PDI position. I analyzed it before.

The analysis is indeed correct, but it may be more difficult for your system to use iodine to catalyze the photocyclization reaction, and the experimental conditions need to be changed.

Well, let me check the literature.

I have already found the literature for you, and I will send it to your mailbox later.

Really, senior brother is really reliable~

It's nothing more than a little effort, Xu Qiu said modestly, and then said: The specific conditions are to use ferric chloride and nitromethane as the catalyst, toluene as the solvent, and react at room temperature. I bought nitromethane before and put it in an explosion-proof In the reagent cabinet, it is unstable and there is a risk of explosion, which is relatively dangerous, so you should pay attention when using it, and it is best to read the MSDS instructions first.

Okay, I remember.

By the way, my three products are fine.

Brother, I have separated and purified the three products, and the yield is about 70%. Do you want to proceed to the next reaction?

Leave about 20 milligrams of each, which will be used for various characterizations later, and throw away all the rest. The next step is the nitration reaction, which is not difficult. Just be careful when using fuming nitric acid.

Uh-huh.

...

In the evening, Xu Qiu did not continue to make the second batch of devices. The data he got this time was enough for the time being. He planned to wait for his third-generation 6/8 series products and the second-generation products of Xuemei. Time to make a few more batches of devices.

During the daytime between depositions, Xu Qiu had already finished his part of the review, and at night Chen Wanqing and Han Jiaying also emailed their part, so he temporarily put aside other things and started to integrate the review The third part, so that when he discusses with Teacher Tang tomorrow, he can show Teacher Tang a more complete version.

After copying the content of the senior sister and the junior sister into the template, Xu Qiu saw the number of pages below the WORD, and couldn't help but slammed his tongue, There are 42 pages. Fortunately, I brought in two helpers as a resourceful person. , or I’m the only one, I’m really exhausted.”

Shaking his head, Xu Qiu got rid of distracting thoughts in his heart and quickly entered the working state, his hands fluttering like nimble butterflies.

After an unknown amount of time, Wei Xingsi's voice suddenly rang in his ears:

how?

Ah? Xu Qiu asked subconsciously before he could react.

How is the device doing today? Wei Xingsi patiently explained in a gentle tone.

Devices... Xu Qiu pondered for a while, and decided that his system should be reserved as usual, and the schoolgirl's would not be necessary. My system is up to 5.5%, and Han Jiaying's is up to 4.4%.

That's right, Wei Xingsi nodded in satisfaction, glanced at Xu Qiu's computer screen, and added, Don't forget to discuss it with Teacher Tang tomorrow afternoon.

Xu Qiu shook his head, was interrupted by the sudden cold, and had to concentrate again before he could enter the working state.

But staying in the Handan campus and working under the nose of the boss, there is no other way.

Two hours later.

It's finally finished. Xu Qiuchang exhaled, glanced at the time at the bottom right of the computer, stretched his hands alternately, and there was a sound at the joint of the bones, muttering to himself:

'The integration was easier than expected, and it seems that the time spent discussing with them in Zhangjiang was not wasted. '

'Now the most troublesome parts 2 and 3 have been completed, leaving the introduction of the first part and the conclusion and outlook of the fourth part. These two parts have been written almost when writing the review plan, and only need to be based on the current situation. The text can be fine-tuned. '

'From this point of view, this review should be written and submitted this week, which is not bad. '

After turning off the computer, Xu Qiu went to the laboratory for a stroll, chatted with others, then packed his schoolbag and walked slowly towards the school bus stop.

His time card was just right, arriving almost at the same time as the last school bus, and Han Jiaying and Chen Wanqing got off one after another.

Under the street lamp, a couple and a...

Xu Qiu took the initiative to ask: Senior sister, your C4 molecule has been synthesized, do you need me to help you make the device? In the previous division of labor, he was mainly responsible for making the device.

I'll do it myself, Chen Wanqing shook her head and refused, The original design path is likely to be problematic. Even if I stay in Zhangjiang and synthesize C2 and C3, it doesn't make any sense. Why don't you test the performance of C4 yourself? Once you get the results, you can make future plans earlier.”

That's okay. Xu Qiu nodded, copied the C4 product from the senior sister, and arranged it for the simulation laboratory, which was an insurance for her.

Well, it really doesn't work. I'll listen to your opinion and try to introduce cyano and fluorine atoms. Chen Wan paused, Actually, I'm more optimistic about this direction.

...

The next day, Thursday.

Xu Qiu got the device performance test results of the C4 system from the senior sister, and the highest efficiency is 1.42%.

Because the initial conditions of the experiment used in the C4 system are based on the C1 system, unlike the PDI system used in the original C1 system, the degree of data distortion will not be too high.

In this case, the efficiency value is only 1.42%, which shows that the potential of the system designed by the senior sister is indeed very limited.

Today, only Han Jiaying came to Zhangjiang Synthetic. She was responsible for a total of five reactions, Xu Qiu's three and her own two. The pressure was quite high.

Xu Qiu planned to dedicate today's time to the review. Sitting at the desk, he glanced at Chen Wanqing who was busy preparing the solution in the laboratory, and thought to himself.

Should I tell her the result?

Forget it, you can’t tell her directly, “Senior sister, your device efficiency is at most 1.5%”.

It is definitely impossible for the senior sister to stop the experiment just because of a word of her own, but she will think that I am cursing her.

It's like stabbing a knife, suddenly the white knife goes in and the red knife comes out, it's easy, but when you insert it and stir it, it's painful.

Seems inappropriate...?

In any case, it is better not to interfere indiscriminately.

At two o'clock in the afternoon, Tang Yunkun came on time, Teacher Wei received him in the office, and then called Xu Qiu over.

Tang Yunkun was sitting on the reception sofa drinking tea, and when he saw Xu Qiu, he greeted Xu Qiu with a smile.

Xu Qiu also responded politely, and then looked at Mr. Tang secretly. It was different from what he imagined. Tang Yunkun was white and fat, and his clothes were loosely supported by his body. His weight was estimated to be 180+, and his height was estimated to be 170-. Once at school, I saw a professor with such an unbalanced figure.

Teacher Wei had already explained it to Teacher Tang before, so Tang Yunkun didn't procrastinate, and went directly to the topic, Shall we start?

Okay. Xu Qiu copied the draft review file to the large computer, and briefly explained the idea of ​​writing.

Tang Yunkun nodded while listening, and at the end, he said: I understand roughly, just let me add some organic photovoltaic theory content, right?

That's right, Teacher Wei answered, Try to write as much as possible, and put up the theories you've been working on recently.

That can't be done, Tang Yunkun shook his head, We are still counting on this theory to publish a PRL.

Xu Qiu was surprised. PRL is the top journal in physics. Although the impact factor is not high, less than 10, its status is similar to that of JACS and Applied Chemistry in chemistry, and AM and EES in materials.

hehe.

hehe.

The two teachers laughed one after another, Xu Qiu seemed to understand something.

Afterwards, Tang Yunkun stopped talking, turned his attention to the big computer, operated the keyboard, and started typing.

Xu Qiu sat next to him, slightly surprised. He thought Teacher Tang would finish the discussion before writing, but he didn't expect it to be this way.

But after thinking about it, this is also reasonable. On the one hand, writing in person is easier to communicate, and on the other hand, maybe Teacher Wei has the consideration of preventing the manuscript from being leaked?

After a while, a paragraph appeared on the computer screen.

We want to point out the importance of excited state theory in non-fullerene organic solar cells, (attributive clause) an appropriate model is what we have to consider...

A pervasive question -- what does the electronic structure of an excited state look like?

Concerning the exciton dissociation state, the generally accepted theory states that excitons are locally generated, followed by an ultrafast charge transfer process...

The ensuing charge separation is caused by the delocalization of the electron wave function and/or the entropy-increasing effect caused by the large number of charge-separated states in the acceptor molecular structure...

Xu Qiu secretly sighed, as expected of a theoretical person, the words were twisted and very obscure, but generally he could understand them, after all, the literature in the past year was not in vain.

Tang Yunkun suddenly asked: In materials articles, how do you usually express the transition state of exciton splitting? Even for theoretical research in the same field, the expression of the physical direction and the expression of the material direction will be slightly different.

CT state. Xu Qiu replied subconsciously, and then realized that Teacher Tang seemed to be communicating with Teacher Wei.

Wei Xingsi, you are a good student. Tang Yunkun tapped the keyboard a few times.

That's not true, Wei Xingsi said triumphantly, I didn't tell you before, but Xu Qiu now has one article on AM, one on AEM, and seems to have two articles on District 2, and he's only a senior this semester.

Amazing, Tang Yunkun turned his fat face towards Xu Qiu, and squeezed out a smile, Young man, how about making a theory with me?

Still poaching corners in front of me, Wei Xingsi scolded with a smile, Xu Qiu will come to my direct blog in the future, write an article carefully.

Tang Yunkun smiled, stopped talking, and focused on the computer screen again.

After such an episode, the communication between Tang Yunkun and Xu Qiu increased a lot.

Next, Mr. Tang mainly coded and occasionally asked some questions, Xu Qiu. answer;

Similarly, when Xu Qiu encountered unfamiliar theoretical knowledge, he would also take the initiative to propose it. Tang Yunkun answered patiently and attached relevant references.

In the end, the two discussed for the whole afternoon and added three paragraphs in total, hundreds of words in length, which greatly enriched the content of the review.
