I Have a Research Support System

After hanging up the phone, Mo Wenlin said to Lu Binghui, Mr. Gong is looking for me.

Didn't you ask me to come with you? Lu Binghui asked hurriedly.

No. Mo Wenlin shook her head.

Then I guess you were chosen as an exchange student. Lu Binghui secretly breathed a sigh of relief.

After Lu Binghui's previous master's tutor had an accident, the tutor was replaced by Gong Yuanjiang. Now, a year has passed, and he finally got to know Gong Yuanjiang. In fact, he didn't want to go to Shanghai. There was a feeling that his tutor had an accident again. , plus his undergraduate degree was also studied at Kainan University, so he still has feelings for Kainan University.

However, he is a good-natured baby, and he has been afraid of teachers since he was a child. When Gong Yuanjiang talked to him and asked if he had any intention to communicate with Shanghai Comprehensive University, he subconsciously agreed. After that, he didn't have the courage to be like Teacher Gong. Explain the situation.

You know, although Gong Yuanjiang is more easy-going towards Wei Xingsi and Xu Qiu, he is also stricter in the group. They are basically ruthless people, ruthless to themselves, and ruthless to their students.

In such an introverted society, no matter what field you want to stand at the top, in addition to relying on illusory luck, hard work is basically essential.

Even the masters of success have to work hard to fool around in order to be able to generate a lot of income.

Mo Wenlin looked at Lu Binghui thoughtfully, and said, Then I'll go.

Her situation is different from that of Lu Binghui. She has not been in Gong Yuanjiang's research group for a long time, and the new environment has little impact on her. Moreover, Dongfa University was also in Shanghai when she was a bachelor and master, so her English level is not very good. He felt that it was difficult to get into the Department of Chemistry at Modu Comprehensive University, so he settled for the next best thing and went to Kainan University.

When Gong Yuanjiang talked to her, she didn't agree directly, but thought about it for three days. During these three days, she read the entire website of Wei Xingsi's research group, including all the latest published articles, and finally found After some analysis of the existence of Xu Qiu's thigh, she thought that if she could hold her thigh, her development would obviously be better than now, so she agreed to Gong Yuanjiang's request.

At that time, she originally regarded Lu Binghui as an imaginary enemy, a competitor, but now it seems that the other party has no intention of going to Wei Xingsi's group to communicate, and is very indifferent to Wei Xingsi and Xu Qiu.

Mo Wenlin really wanted to ask: Then why did you agree with Mr. Gong in the first place, and forced a 'competitive election'? Of course, she just thought about this in her heart, and she definitely wouldn't ask it.

Gong Yuanjiang's office.

Mo Wenlin, after that you will go to Teacher Wei Xingsi's group for a two-year exchange. Gong Yuanjiang said straight to the point.

Okay. Mo Wenlin hurriedly responded.

When can you come to Shanghai? Wei Xingsi asked.

Hmm... Mo Wenlin hesitated for a moment, then said, You can do it anytime, I don't have much luggage.

By the way, Gong Yuanjiang interjected: She hasn't got her master's degree certificate yet, and she's renting a house here to live outside. It can be settled at your place. The rent in Shanghai is not cheap.

This is a trivial matter, I will find a way. Wei Xingsi said tentatively, If possible, why don't you come back to Shanghai with us directly after the meeting next Monday?

No problem. Mo Wenlin nodded.

The exchange procedure can only be done after school starts, Gong Yuanjiang reminded: She is still a black household for the time being, so you have to be careful when doing experiments, otherwise something will go wrong and it will be more troublesome.

Of course I know this. Wei Xingsi paused, and said, Since the candidate has been determined, Yuanjiang, let me give you a message. Have you read the AEM article that our team just published?

Oh... That article, I have impressions, I have impressions, Mo Wenlin, tell me about it. Gong Yuanjiang said.

Mo Wenlin said without hesitation: The latest AEM of Teacher Wei's research group is to report an ADA-type non-fullerene acceptor material named IDT-ICIN, combined with FTAZ donor material, the photoelectric conversion efficiency of the device can be increased. Up to 6%...

Xu Qiu secretly murmured that Mo Wenlin must have done her homework in advance, because most people would only remember the general idea of ​​this kind of document that is not her work.

ICIN, this is a new structure, Gong Yuanjiang wondered, Is there anything special about it? Xu Zhenghong's IDTBR has reached 10%, and I heard that it will break through again.

Really? Have their articles been submitted? I don't know about it yet. Wei Xingsi was surprised, and Xu Qiu was also surprised. Since it can be called a breakthrough, it must not be a trivial increase of 0.1% or 0.2%. , with a high probability of an increase of 1% or even higher.

It's still Liang Haoxian's work. I heard from them yesterday, Gong Yuanjiang explained, It seems that the side chain has been changed. The new materials are called IDTBR-EH and IDTBR-O. The efficiency just broke 11%. You voted for EES. Just know it yourself, but don’t spread it outside.”

Okay, keep it secret. Wei Xingsi promised.

By the way, just now you said the structure of your ICIN... Gong Yuanjiang changed the topic back.

Oh, our system has also made a breakthrough, and now the efficiency is more than 6%. Wei Xingsi said calmly, Xu Zhenghong's new IDTBR system, if it only changes the side chain, it will not have a big impact on the ITIC series in his group .

8%? Gong Yuanjiang observed Wei Xingsi's expression, and continued, 9%? More than 10%?

That's right, Wei Xingsi nodded: And it's just a preliminary result, there is room for further improvement.

Gong Yuanjiang looked at Xu Qiu who was next to Wei Xingsi, and said, Is this your job, classmate Xu Qiu?

Well, the ICIN unit is my initial idea. Our team's senior sister Chen Wanqing is in charge of synthesizing it. Recently, the system with an efficiency breaking through 10% was designed and synthesized by myself. Xu Qiu said simply, no The published work does not go into too much detail.

Mo Wenlin looked pleasantly surprised. It seems that now is the right time to join Wei Xingsi's research group. Xu Qiu and the others have just developed a new type of molecular structure. Go in and give her a small idea. Steady, even the article in the first district is not hopeless, as expected, hugging the thigh is the right way, Lu Binghui still doesn't know what opportunity he missed.

Okay, then I have to study the structure of your ICIN. Gong Yuanjiang's expression became serious. This news is also very important to him.

For the field of organic photovoltaics, every system that can achieve double-digit efficiency, that is, more than 10%, is worthy of attention, because there are not many such systems.

Now two types of ADA materials have suddenly appeared in the non-fullerene field, and the efficiency has reached more than 10%. In addition, Wei Xingsi's research group has refreshed the value of the PDI system to about 9.5%. It is estimated that breaking 10% will happen sooner or later.

There are various signs that the field of non-fullerenes is brewing.

Each research group has its own subdivision field that it is good at. Although Gong Yuanjiang's group has dabbled in various systems, it is better at the development of small molecule donor materials. This is a relatively small field with few researchers. The best one is Gong Yuanjiang. In recent years, he feels that some researches are not moving, and he can't break through in efficiency, and he can't see the way forward.

Now Gong Yuanjiang has a choice, which is to change the research focus of his research group and switch to a non-fullerene system.

As the saying goes, a small boat is easy to turn around. A large research group has a series of advantages, but it also has disadvantages. Like Gong Yuanjiang’s group, once the main research direction is changed, many of the advantages brought about by previous accumulation will no longer exist. empirically, does not transfer synchronously to non-fullerene acceptors.

Gong Yuanjiang considered carefully for a while, and made a decision: The main research direction in our group is about to change. Thank you Brother Xingsi for telling me the news.

Don't be polite between us. Wei Xingsi smiled and waved his hands. He told Gong Yuanjiang that the main reason for the news was the exchange student program.

Mo Wenlin came to his group, a bit of a spy. If she is not allowed to get in touch with the core experiment of the research group, then why bring her here, but if she gets in touch with the core experiment, there is a high probability that she will tell Gong Yuanjiang After all, articles published by Mo Wenlin's work must bring communication between the two parties.

After thinking about it, Wei Xing might as well take the initiative to tell the news and get a favor. Although he and Gong Yuanjiang were good friends before, they were just good friends. There was no exchange or bondage of interests. They can be regarded as friends, but now it is different. The two can become hard-core allies, form a cooperative alliance, build a similar system, and exchange experimental plans, at least they will not crash.

Brother Xingsi, let me tell you some news too, Gong Yuanjiang said suddenly:

Zang Chaojun and Lu Changjun's research found that for the fixed-area battery device in the traditional beautiful country, when the light irradiates the entire active layer area, there will be a lateral photo-generated current, which leads to certain differences in the measurement results of the short-circuit current density of the device. error.

Therefore, they promote the preparation of large-scale battery devices, and then use a fixed-size mask to calibrate the effective area, which has many advantages, such as preparing a single device, theoretically, an infinite array of battery devices can be obtained...

I've heard of this... Wei Xingsi pondered for a while, then said, Are they planning to advance in the direction of application?

Yes, if you want to apply in the field of organic photovoltaics in the future, you must take this step. You can't always make battery devices as small as 0.04 or 0.09 square centimeters. Gong Yuanjiang bent his middle finger and gestured for several areas: A device of 1 square centimeter, I think, is just the start.”

The application of organic photovoltaics, can we see that day? Wei Xingsi seemed a little pessimistic.

We always have to work hard in this direction, don't we? Gong Yuanjiang asked firmly.

Well, you're right. Wei Xingsi smiled and nodded.

The ultimate goal of scientific research is application, but in fact, most of the directions are dead ends, and very few fields that can be applied are the results of many years of grinding.

Just like lithium batteries, lithium metal batteries were first proposed and researched by Gilbert N. Lewis in 1912, and they were only commercially available in the 1970s. After the 1990s, they were replaced by lithium-ion batteries due to safety issues. Now lithium-ion batteries are widely used in mobile phones. , computers and other electronic products.

Scientific researchers at the level of Wei Xingsi and Gong Yuanjiang naturally know that the application of organic photovoltaics is likely to be a series in their lifetime, and it may be developed in 50 or 100 years. There are names on the monuments composed of historical documents, but at least for now, if you choose this scientific research path and choose this field, you must take responsibility and cannot shrink back.

Xu Qiu has no idea what the future of the organic photovoltaic field will look like, but he is quite optimistic. After all, he has a system in hand. If more functions can be unlocked in the future, there may be a chance to greatly promote the organic photovoltaic field. process of industrialization.

After the exchange between the two teachers, Wei Xingsi confessed to Xu Qiu: Come to my room at eight o'clock in the evening and sort out the report for tomorrow and Sunday. He was going to visit several other teachers in the afternoon and did not plan to bring Xu Qiu along.

Xu Qiu was also happy to have a leisurely time, and just happened to be able to take a stroll around Jincheng, but there was no one for lunch and dinner, so he had to solve it by himself.

Before parting, Mo Wenlin added Xu Qiu's WeChat, and Xu Qiu conveniently dragged her into the group chat of the research group, and introduced her to other friends.

Everyone expressed their welcome, and Tian Qing joked, Xu Qiu was on a business trip, so he abducted another girl back.

Han Jiaying also sent a hatchet emoji, and Xu Qiu hurriedly explained to her that although she knew that the school girl was not the kind of stingy person, girls were meant to be coaxed, so she still had to show her attitude.

In the afternoon, Xu Qiu casually went out for a stroll, and Mo Wenlin sent him a message saying I want to be a tour guide, but he rejected it. How could he have lived in Shanghai for seven years, and only came to Jincheng for a few days? , as a tour guide for others, Mo Wenlin is not from Jincheng either.

Xu Qiu didn't go too far, so he visited two adjacent universities, Kainan University and Jincheng University, both of which are 985 universities.

Then, he found that the universities were similar, and there was not much difference between the two universities and Shanghai University.

PS: For the first time, I didn't save my manuscript every day, which is worth commemorating...

PS2: The current monthly ticket is 850+, owed 2W7, and 8000+ has been repaid.

PS3: Tomorrow is still the third shift.
