I Have a Research Support System

On Sunday morning, Wu Feifei received a call from Wei Xingsi.

Wei Xingsi: Wait, you go to the airport to pick up Feng Shengdong. He is already on the plane. He is estimated to arrive at Shanghai Pudong Airport at noon today. I have sent you the flight number on WeChat. You can first check to see if the plane is delayed.

Wu Feifei: Okay, where is the pick-up arrangement? Yanyuan Hotel?

Wei Xingsi: Well, yes, I've already booked the rooms at Yanyuan Hotel, just report my name when you go.

Wu Feifei: Oh, yes.

At the beginning, Wei Xingsi contacted Feng Shengdong and Tnu from Lund University in Sweden, mainly to make up for the shortcomings in the research group on the mechanism of organic photovoltaics.

But later, Wei Xingsi found that the TAS, TRPL, THz and other test and characterization methods provided by Sweden were more suitable for the research of perovskite, so he increased the cooperation between the two parties in the field of perovskite.

Now almost every piece of perovskite work in the group is completed in cooperation with Sweden, and the corresponding authors of both parties are linked.

Articles on organic photovoltaics, such as conventional material development work, are mostly done alone in the group, or with Gong Yuanjiang. Only work involving mechanism explanation will bring Feng Shengdong and the others to play together.

In addition to Wu Feifei being assigned a task, Xu Qiu was also summoned to Caiyi 216's office to stand by.

At about 9:40 in the morning, Wei Xingsi appeared at the door of 216, smiled at Xu Qiu and said, Some teachers will come over early today, and I will trouble you to communicate and discuss together.

Okay, no problem. Xu Qiu nodded in agreement. He had already received the news on Friday.

The teachers who came here today basically have a good relationship with Wei Xingsi, so we can maintain the relationship and have private academic exchanges.

In the academic circle, academic exchanges between colleagues are still very important.

Academic papers are the most extensive means of academic communication. After hundreds of years of evolution, scientists circulated manuscripts to each other in the early days, and later the journal company was established and began to publish paper journals, and now electronic journals have basically become popular. .

The general trend is that researchers communicate with each other more efficiently and more conveniently.

Researchers can learn about the variety of different possibilities in a field by consulting other people's published articles.

However, academic papers are limited in length after all, it is impossible to show all the experimental details, and it is also impossible to realize real-time communication between researchers.

In terms of communication efficiency, looking at other people's academic papers is far inferior to direct face-to-face communication.

This is the significance of holding various conferences every year.

Although various conferences are ridiculed by people as public tourism and big bosses bragging, their existence is still very necessary.

In the future, if the scientific research field continues to develop, a better communication model may be born.

For example, bring together all the researchers in the same field, pool their brains and efforts, communicate with each other, and communicate in a timely manner, and even gather scientists from all over the world to jointly tackle a certain problem.

It is similar to building a huge research institution and integrating all the resources that can be integrated.

Of course, this is an idealized situation, which is difficult to realize in reality. After all, everyone has their own interests, and every country also has their own interests, so they cannot be united.

But from the point of view of the entire civilization, only when the great unification is achieved can it develop to the greatest extent.

If the internal friction continues like this, human civilization may be shackled on the blue star forever.

Have you finished reading the literature, come and talk about it? Wei Xingsi asked.

I've finished reading. Xu Qiu replied, then picked up the document, and followed Mr. Wei to 218.

...Ma Weiwei's research group, AEM article, materials purchased from Blue River Optoelectronics, ITIC and IEICO, they used toluene as a solvent to spin-coat the active layer, and at the same time conducted a stability test...Xu Zhenghong's research group, NC article, they Developed a non-conjugated D-unit ITIC-like molecule with high stability... Yan Hu's research group, AM article, they modified PCE11 donor materials and obtained two wide-bandgap donor materials , and combined with ITIC2...

Xu Qiu was eloquently reporting on the literature, and now his way of talking about the literature is very different from when he first started.

When he first started, Xu Qiu didn't have enough understanding of the field of organic photovoltaics, and he couldn't grasp the key points when talking about the literature, so he could only use a rough method, that is, translate the abstract and conclusion with the literature, and then Look at each picture in turn and talk about it.

Using this method, it takes three to five minutes to finish a document, and it takes nearly an hour to talk about a dozen documents at a time, and each lecture is a big project.

Now, Xu Qiu understands the meaning of literature, which is actually to share the core points of an article with others, and he already has the ability to grasp the main points of the article.

Like some small articles, it can be summed up in just one sentence, similar to: Zhang San made an acceptor material Z3, the structure is based on the improvement of their previous Z2 material, combined with PCE10 donor, the device performance is 10.5% .”

If it is a big article, usually there will be more bright spots and the story will be more complicated. Xu Qiu will point out every bright spot and make every story line clear.

If this article is related to what he is currently doing or the work he plans to do in the future, he will also talk about how to apply other people's ideas to his own system.

In this way, the time to talk about a document can be compressed into half a minute, or within one minute, which greatly saves time.

When Xu Qiu was making a document report, Wei Xingsi was not idle either, he was sitting at his desk operating the computer.

Soon the printer started working, humming.

At first, Xu Qiu thought that there was a new document coming out, but he glanced at the printer, only to find that it was the Natural·Energy article just received by the group, which was typed out by Wei Xingsicai.

Every time the research group publishes an article, Mr. Wei will print out the article in color when the article is officially published, that is, after the proof (verification), and when the electronic version comes out, and put it in the office so that you can read it at any time.

This time is quite special. This article Natural Energy was accepted just after being notified on Friday. The editor has not yet arranged the version, and the electronic version has not yet been released.

In other words, other researchers could not find this article on the Internet for the time being.

Xu Qiu didn't quite know the purpose of Teacher Wei printing it out, but he didn't care too much.

As for the articles published by other research groups that the group usually reads, if it is a general second district article, it will be printed in black and white, and if it is a high-end first district article, it will be printed in color.

Of course, the premise is that the corresponding article is published in color.

Many journals will charge authors for color pictures. If you do not pay, the pictures will be black and white.

According to Xu Qiu's observation, most of the electronic PDF files of journals under ACS and RSC are color pictures.

However, for Wiley's journals, such as AM and AEM, many of the pictures in the electronic version of the document PDF files are black and white.

Probably because the cost of color pictures is relatively expensive. It is said that a color picture costs hundreds of dollars, and some even close to 1,000 dollars.

It's a few hundred dollars, not all of them add up to hundreds of dollars. To be honest, this fee is quite exaggerated, and it's not an exaggeration to call it a money grab...

Therefore, few people take advantage of the review articles published on AM, and the pictures are basically black and white.

And review articles will have the author's personal introduction, so every time Xu Qiu reads the AM review, a few black and white headshots hang in the article, there will always be a bad association...

Fortunately, the two reviews published by Xu Qiu, one on ACSEL and one on Joule, were published in color. He didn't know the cost, but it should be free or relatively low.

However, the main color of these two journals is green, which looks green, and there will also be a bad association...

After Xu Qiu finished his last document, he was about to leave and returned to 216 to wait.

At this time, there was a Dangdangdang knock on the door suddenly outside.

Wei Xingsi said angrily, Please come in!

The door was pushed open, and two strange girls walked in.

One of them is about thirty-five years old, a little short, only about 1.6 meters, and has a very capable temperament.

Xu Qiu compared the list of visitors he had learned before, and speculated that this person was probably Wei Xingsi's junior sister, Ma Weiwei.

The other one seemed to be about the same age as Xu Qiu, and looked younger and a little shy. He was probably Ma Weiwei's student and was brought out to see the world together.

Wei Xingsi greeted him warmly, waved his hand and said, Ma Weiwei, you're here, so fast.

As soon as I got off the high-speed rail, I just took the subway and rushed here. Ma Weiwei smiled, and then stretched out her hand gracefully.

After the two shook hands, Wei Xingsi turned around and pointed to Xu Qiu, and introduced to Ma Weiwei, This is the pillar of our organic photovoltaic team, Xu Qiu.

Young and promising, Senior Brother Wei often mentioned you to me before. Ma Weiwei looked Xu Qiu up and down, and reached out to him, and the two shook hands.

Ma Weiwei's hand is not very soft, it's very different from the usual tactile feedback when grasping a schoolgirl's little hand.

Xu Qiu couldn't help feeling in his heart: Time is like a butcher's knife.

Of course, it may also be caused by long-term chemical experiments and exposure to organic solvents. Green pepper scholars of this age will most likely still have to do experiments on the front line.

This is my student, Hu Yaoyao. After returning to China, I only recruited one master student. Ma Weiwei briefly introduced, and then under Wei Xingsi's guidance, she and Hu Yaoyao sat down on the reception sofa.

Wei Xingsi took the initiative to ask: How is the development now, are you still used to it when you return to China?

Ma Weiwei gave a hmm and said, Fortunately, it's just that the laboratory needs to be re-established when returning to China, and the start-up funds are not much, so the conditions are a bit difficult.

Wei Xingsi smiled: Take your time, it's been more than a year on my side, and scientific research has only improved.

Ma Weiwei nodded: Yes, everything is difficult at the beginning.

...

The two chatted awkwardly for a few minutes, Wei Xingsi picked up the hotly printed Natural·Energy article from his desk, handed it to Ma Weiwei, and said happily:

You don't know yet, our group's latest article Natural Energy has just been accepted. The IDIC-4F system made by Xu Qiu has achieved a device efficiency of 13.5%, and has also carried out a very careful theoretical analysis...

Wow, amazing! Ma Weiwei exclaimed, took the document from Wei Xingsi's hand, flipped through it, and responded:

Senior Brother Wei, you have developed well after returning to China. It is also a major sub-journal of Nature and a review of Joule. It is estimated that AM, JACS, and EES have published ten articles.

Wei Xingsi waved his hand and said, You also have an article on AEM recently, we were still discussing your article just now.

Ma Weiwei thought to herself what a coincidence, and then asked curiously: How is my work, and I can catch the eyes of the two of you?

Wei Xingsi turned his head to look at Xu Qiu, motioning for him to answer.

Xu Qiu had no choice but to bite the bullet, squeezed out a polite smile, and responded after a little thought: Mr. Ma Weiwei's article is very good and inspiring. We plan to use environmentally friendly non-halogenated solvents in the future to replace the traditional ones. Chlorobenzene, chloroform solvents.

Although Xu Qiu complained about Ma Weiwei and the others when they changed chlorobenzene to toluene before when they were reading literature, they dared to claim to be environmentally friendly. See you.

Ma Weiwei smiled and shook her head: I still know my own articles. Compared with your work, it's nothing worth mentioning.

After a pause, Ma Weiwei added: Oh, by the way, I think this Nature·Energy is well written, can I take it home?

Wei Xingsi made an excuse gesture: Of course.

Ma Weiwei rolled up the article and put it in the bag she carried with her, and then said: I came here this time, mainly to ask Brother Wei for advice on the choice of non-fullerene systems.

Wei Xingsi tentatively asked, Are you planning to develop a new system yourself?

That's right. Ma Weiwei nodded.

This idea is correct. If you want to have a long-term development, you must build a complete system yourself, and then dig deeper. After a pause, Wei Xingsi asked casually: Hmm...do you have any preliminary plans?

Ma Weiwei responded quickly: I originally planned to make ITIC-related ADA receptor molecules, but later found that there was too much competition in this direction.

I won't talk about it here. I see that many other large groups have started to follow up, especially Xu Zhenghong, who is about to give up his own IDTBR system. The few articles published recently are all about ITIC.

So, I don't really want to squeeze on this track.

Some time ago, I came up with an experimental idea, which was mainly based on the research on PDI and NDI polymer receptors conducted at NREL in the beautiful country. The specific idea is to polymerize ITIC.

It turned out that not long after this idea came into being, I saw your review of Joule, which was mentioned in the prospect section above...so I came over to ask.

That's it. Wei Xingsi nodded, and understood Ma Weiwei's appeal. He was afraid of colliding with the experiment in his group, so he came to find out.

Therefore, Wei Xingsi looked at Xu Qiu and asked, Do you have any plans in this direction?

Xu Qiu considered it for a while, and replied: I don't plan to do it for the time being... But I think this direction is feasible, and it can be done like this...

Ma Weiwei listened very attentively, and interrupted Xu Qiu halfway, took out a notebook from her bag, and wrote down a few notes from time to time.

Xu Qiu had already designed the experimental plan for the ITIC series of polymer receptors, and explored it in the simulation laboratory.

For example, IDIC is polymerized, that is, the ICIN unit on the end group of IDIC is replaced with bromine, and then reacted with bistrimethyltin-substituted thiophene to form a structure of ...-IDIC-T-IDIC-T-... .

The final device efficiency is not low, can reach more than 11%.

This system, if you work hard, you may not be able to post a few articles in the first district, and even AM has a chance.

However, the problem of this system is also obvious, that is, the end group of ICIN cannot be modified, such as the introduction of chlorine atoms and fluorine atoms.

In other words, making ITIC series acceptor materials into polymers has little room for breakthroughs in terms of efficiency, which may increase the stability of the device, and it is temporarily a leftover work.

Therefore, Xu Qiu did not continue.

Moreover, there is a shortage of manpower in the group. Now everyone's work is full, so we can only make a choice and give priority to completing those more artistic-worthy tasks.

In fact, in the prospect section of the review of Joule, Xu Qiu wrote down many feasible ideas that he has explored and found, which is equivalent to BONUS, whoever picks it up will get it.

Xu Qiu can be regarded as a relatively conscience review author.

Many review authors, in fact, simply summarize the work of other people, without their own thinking in it.

Everyone chatted for a while, and the time was close to half past eleven.

Wei Xingsi extended an invitation to Ma Weiwei and said, Have a light meal together at noon?

Ma Weiwei didn't refuse either: Okay.

Xu Qiu didn't plan to follow along. He estimated that if he and Hu Yaoyao hadn't been present, the meeting between Wei Xingsi and Ma Weiwei might not have been so scientific...

Then I'll leave first. Xu Qiu resolutely resigned.

As a result, he retreated a bit slowly, and received a task sent by Teacher Wei: Xu Qiu, help welcome Ma Weiwei's students.

Okay. Xu Qiu had no choice but to agree, and took Hu Yaoyao to the cafeteria, and chose the slightly better WE COFFEE restaurant in the North District.

Hu Yaoyao is a relatively quiet type, not as enthusiastic as Mo Wenlin was at the beginning, and she doesn't take the initiative to speak. Basically, it is Xu Qiu who introduces her.

During the chat, Xu Qiu learned that Ancheng Jiaotong University, where Ma Weiwei was studying, was a member of C9 universities, just like Modu Comprehensive University.

Hu Yaoyao's undergraduate course is a general undergraduate course, and she passed the compulsory postgraduate entrance examination. She passed the entrance examination and entered the interview, and was finally admitted. She is now in the first year of a master's degree.

In Ma Weiwei's AEM, the experiments were basically done by Ma Weiwei herself, and Hu Yaoyao was in charge of helping out and learning various experimental skills along the way.

Hu Yaoyao spoke highly of Ma Weiwei, saying: Her mentor is very good, capable, and very hard-working.

Xu Qiu was not very surprised by this. Few of the girls who can be mixed in the scientific research circle are sheep.

This refers to the girls who can be professors in science and engineering, basically they are all fierce.

After eating, Xu Qiu sent Hu Yaoyao back to Yanyuan Hotel, while he returned to his dormitory.

At 1:30 in the afternoon, Xu Qiu was summoned to Wei Xingsi's office again.

He looked at the newly printed Nature·Energy article on Mr. Wei's desk, thinking.

Not long after, Mo Wenlin led Gong Yuanjiang into room 218.

This time, Gong Yuanjiang also brought a student, who was Cao Si, the big brother who took Xu Qiu and the others out to play board games last time.

They are all acquaintances, so the communication with each other is much more casual, and there is no such thing as a handshake.

Gong Yuanjiang joked with a smile: Mo Wenlin, you're doing okay here, Mr. Wei and the others didn't bully you, right?

No, no, Mo Wenlin quickly waved her hands, Ms. Wei is very kind to me, and the students in the group are also very kind.

However, when speaking the second half of the sentence, Xu Qiu felt that Mo Wenlin seemed to glance at him.

Wei Xingsi picked up the Natural Energy article from the table and handed it to Gong Yuanjiang: The Nature Energy article that was just received this Friday has not yet come out on the Internet. Let me take it for you to take a look first.

Gong Yuanjiang's smile froze: You forgot, I am also one of the authors of this article, and you called me on Friday...

...haha, I've been too busy these days, I forgot. Wei Xingsi smiled awkwardly, and changed the subject abruptly: By the way, we have made new progress in the experiment now.

Gong Yuanjiang became interested: Oh? What aspect?

Wei Xingsi looked at Xu Qiu and said, The development of new materials and stacked devices can just cover the key projects we plan to apply for.

That's pretty good, how much have you achieved now, 14%? Gong Yuanjiang also looked at Xu Qiu, and realized that the high probability was again Xu Qiu's credit.

The current efficiency is 14%, close to 15%, but... Wei Xingsi changed the subject: Xu Qiu said that he is confident that he can achieve 16%!

??? Xu Qiu was stunned, and said in his heart: When did I tell you that I can achieve 16%? Oh... It seems that I mentioned a sentence 'hopefully 15%, or even 16%', but it didn't So sure, okay...

Really, this is the rhythm of nature. Gong Yuanjiang exclaimed, Cao Si and Mo Wenlin were also a little surprised.

Mo Wenlin is actually fine, she is almost superstitious towards Xu Qiu now, and she may not necessarily believe the 16% that others claim, but if Xu Qiu said this, it seems to be the truth, there is no doubt about it.

Cao Si is the most emotional. He has been in the industry for nearly five years and has been working on the small molecule donor system, and the efficiency has been kept within 10% all year round.

This year, I finally encountered ITIC-type non-fullerene acceptors, and broke through the device efficiency of the whole small molecule system to more than 10%. I am very happy to write an AM.

Now I heard that people are already 14%, and they are hitting 15%, 16%...

Why is there such a big gap between people?
