I Have a Research Support System

What is a higher mountain?

The answer is obvious, the major sub-journals of Nature, and even the main journals of Nature and Science.

Similarly, the difficulty of reaching the top is also obvious, and a major breakthrough must be made. Even if Xu Qiu has the system, it is still not so easy to do.

From SCI District 2 to District 1, although the difficulty of publishing articles has increased a lot, it is only a linear increase. From the top journals of AM and NC in District 1 to the major sub-journals of Nature and the main journal of CNS, The difficulty of publishing is an exponential leapfrog improvement.

A very simple example, if you can publish an article in Nature at the graduate level, after graduation, you can go directly to a foreign university such as Oxford, Harvard, Massachusetts, Cambridge, and find a big team to study for two years. The biggest opportunity is to directly introduce talents as young thousand, and then become specially-appointed professors or researchers in 985 universities.

For domestic professors, if they can post an article on Nature and don't hold back in other aspects, they will basically be awarded the title of Jieqing. In other words, Xu Qiu published an article Natural, Wei Xingsi, who is still a young thousand, will soon be rated as an excellent young, basically he doesn't need to use personal connections, and he can make progress while lying down.

...

Brother, if you don't want to do it alone, then let's work together, Han Jiaying chuckled, I'm on top and you are on the bottom.

What kind of broken road, you can drive. Xu Qiu raised his hand and tapped the junior girl's head, but this time he did not refuse again, It's up to you.

The other B3T-6 system, how about having my brother write an article for you? Han Jiaying suggested again.

No, I don't need it. Xu Qiu shook his head.

No, you want it. Han Jiaying insisted.

Could it be that you don't want to write an article? Xu Qiu thought for a moment and asked suspiciously.

No, it's not... Han Jiaying explained in a panic.

Huh? Xu Qiu's tone was slightly accentuated.

Indeed, part of the reason is like this. After being exposed, Han Jiaying admitted frankly: Writing articles is so boring, but doing experiments is interesting, brother, can you please~

Xu Qiu thought about it for a while, then nodded and said, Okay, anyway, the data is complete, and if you vote for ACSAMI, you don't need to write too seriously. After the EES in my hand is voted out, just spend a week writing it. .However, this is not an example.

Brother is so kind~ Han Jiaying rubbed Xu Qiu's body coquettishly, and said, The food here is so slow. It took more than ten minutes for two cans of Coke to come.

We had dinner at six o'clock, and it's only past nine o'clock now... Xu Qiu complained.

Isn't it because I knew there was a supper at night, so I saved my stomach on purpose. Han Jiaying explained, and then said after a pause: After all our 3D-PDI system articles are published, should we continue to try other PDI systems?

No need, Xu Qiu shook his head and said, It is enough for us to publish all the articles in our hands in this field, and we will not be able to publish more unless we increase the efficiency to more than 10% or come up with some new ideas. Good articles, at most they are weak areas like JMCA and CM.”

After a pause, Xu Qiu continued to analyze: At present, I estimate that the upper limit of the PDI system is about 10%, or if it is further estimated, it can reach 12%, and there is a high probability that it will not be able to surpass the fullerene system. And I want to It is not easy to reach the value of 10%. It must be a lot of material synthesis and device optimization, which requires repeated trial and error. The cost performance is too low. The energy is left for a better direction.

Then shall we also work on the ADA system with my senior sister? Han Jiaying understood the hidden meaning in Xu Qiu's words.

That's right, the focus of our work will be shifted to the ADA field, Xu Qiu nodded, explaining: Just now Xu Zhenghong and his colleagues published an article Nature Materials, raising the upper limit of the efficiency of the non-fullerene field When it reaches 10%, although in the short term, the threshold for publishing articles has been raised, which is especially unfavorable to seniors, but in the long run, it can hype up the popularity of this field and attract other researchers to study together.”

There is indeed a competitive relationship between researchers in the same field, but what is more important is the cooperative relationship. At the current stage of scientific research development, if you want to promote the development of a large field, the power of one person or a research group is not enough Yes, even a big academician needs a group of younger brothers to help.

For example, in the field of organic photovoltaics, some people are responsible for developing donor materials, some are responsible for developing acceptor materials, some are responsible for studying the charge transport mechanism, and some are researching new transport layer materials to optimize device performance from other levels. To a higher level, or to study roll-to-roll processing, environmentally friendly solvents, large size, flexibility and other technologies related to commercialization, which will pave the way for the application of organic photovoltaic devices in the future.

The more researchers there are, the more popular the field will be. The hotter the field, the faster the development. The faster the field develops, the more newcomers will enter the field, thus forming a virtuous circle; Without a major breakthrough to break the vicious circle, it will eventually die out; this is also the embodiment of the Matthew effect, the winner takes all.

Of course, the most critical reason is that I think the future of the field of organic photovoltaics, Xu Qiu paused, and said seriously: It's in the field of non-fullerenes!

Brother, do you have any specific research plans? Han Jiaying asked.

Is it a plan? Xu Qiu rubbed his head in embarrassment, Is it a plan to adapt to changing circumstances?

Responsiveness... Han Jiaying raised her forehead, I thought my brother was already prepared.

Xu Qiu spread his hands and explained: The field of ADA-type non-fullerene acceptors is not like the PCE11 and 3D-PDI systems that we did before. There are existing systems for reference, which means that we can judge in general. But the specific details cannot be known in advance, and we and other colleagues need to continue to explore.

Han Jiaying curiously said: Some preliminary work of Xu Zhenghong's group can also be used for reference.

Well, the synthesis method can be used for reference. After all, many synthesis reactions are of the same type, Xu Qiu changed the subject: However, there is almost no room for reference in terms of molecular structure design. There is no way. Their previous efficiency data is too low. Most of them are within 5%. To give a very simple example, they did some molecular structure optimization, which increased the efficiency from 2% to 3%. This level of improvement may be caused by experimental errors, or The device processing conditions of the low-efficiency system have not been optimized in place.”

What about the Nature Materials they just published? Han Jiaying turned into a curious baby.

Hmm... Xu Qiu thought for a moment, and explained: Although that work has increased the efficiency to 10%, it is only an isolated case. In addition to providing me with an idea to sandwich other units between D/A units, and Except for the idea of ​​stability research, there is not much reference value in other aspects.

Unless we imitate them and develop derivatives of IDTBR, such as changing the side chain on the central D unit, or adding something to B and R...

But this is not what I want to do. I think it is better to use the ICIN unit developed by our group, and the senior sister broke the world record of the ADA system, right? It only lasted for one day.

One day... Han Jiaying chuckled, It's pretty impressive.

Xu Qiu took a sip of iced cola and said, Actually, I don't have any plans at all. The general direction is to synthesize a series of fullerenes with different band gap widths or light absorption ranges based on our ICIN unit. Acceptor molecules, and then based on these acceptor molecules, according to the principle of light absorption complementarity and energy level matching energy, a series of suitable donor materials are synthesized...

I see~ Han Jiaying had an idea: This is called giving and accepting two blossoms!

What two blossoms, it's really easy to cut. Xu Qiu retorted: Obviously, it is grasped with two hands, and both hands must be hard to cut.

I haven't finished talking just now, Xu Qiu continued: My idea is to build a rich donor library and acceptor library, match them in pairs, get the optimal system, and build a theoretical model for receptor adaptation. After that, it can also be developed on the concept of translucent and stacked battery devices.

It sounds like a lot of work. Han Jiaying tilted her head.

Xu Qiu said relaxedly: Take your time, besides us, there are hundreds of peers. However, in the future, it is estimated that Mr. Wei will be troubled a lot to go out for PY transactions. Help us find other research groups and get some materials back.

Han Jiaying asked: Brother, what do you mean by PY? Is that what I think?

Xu Qiu thought for three seconds before explaining: PY, that's a friend. I read it like a friend, a doctor, a friend.

Han Jiaying's difficult pronunciation: Pang, you, you, your friend~

Yes, not um, friends, not friends. Xu Qiu taught patiently.

Poe, um, friend~ Han Jiaying blushed.

Xu Qiu spread his hands, it turned out that the school girl couldn't distinguish the nasal voice from front to back, and he usually didn't notice it.

At this time, the waiter brought two large pots of crayfish and a large bag of disposable gloves, Your crayfish are here, and the side dishes are at the bottom.

It's finally here, I'm so hungry. Han Jiaying couldn't wait to put on the gloves, feel it, and said: I always feel like I'm going to enter the laboratory, but these gloves are compared with the disposable PE gloves in the laboratory. , too thin.

It's cost-saving. After all, even if the glove leaks here, there is no danger. Xu Qiu explained casually.
