I Have a Research Support System

After the group meeting ended, everyone left one after another, Xu Qiu stayed alone, and spent more than ten minutes with Teacher Wei, going through his own article again.

During the discussion, Xu Qiu could tell from Wei Xingsi's expression that Mr. Wei attached great importance to this NC article, obviously more than the AM article he published before.

It is not difficult to understand that if this NC can be published smoothly, it will be Wei Xingsi's first corresponding author for the first journal of "Nature" after returning to China, which is a small milestone event.

You must know that Wei Xingsi has done research abroad for more than ten years. Although there are several first-author articles in the top journals of AM and JACS, such as AM and JACS, none of the articles at the beginning of "Nature" is the first author or the first author. of a corresponding author.

Wei Xingsi did have articles in the big sub-published "Nature" with two, three, four, five, six, seven eight authors, or the second and third corresponding authors, and the number was quite a lot, close to ten.

In general, Teacher Wei's scientific research ability may not be top-notch, but his PY skills are really good.

As a small sub-journal of "Nature", NC is at the same level as AM. The former may be slightly stronger than the latter, but not too much stronger. The initial positioning for NC was to recycle those journals that hit the main issue of "Nature" or A manuscript that failed for a large sub-journal.

People's pursuit of NC is more because it carries the word "nature", just like the so-called "NC second" Sci. Perhaps it is because there is no N on the journal name.

After all, the status of the three top journals of "Cell", "Nature", and "Science" is recognized in the academic circle, and most researchers are eager to publish an article in the three top journals, so as to have the opportunity to mix The top circle of academia.

However, the reality is cruel. Most people in the world are mortals, and most scientific researchers are just ordinary scientific researchers. It is impossible for everyone to achieve shocking results.

They think that they cannot publish the three top journals of CNS, and it is not easy to publish their major sub-journals. Taking the major sub-journals of "Nature", such as "Nature Materials", their impact factors are similar to those of the main journal. Around 40, some are even higher than the main journal, and many articles published on it are not necessarily less influential than articles published on the main journal.

If the main journal cannot be published, neither can the major sub-journals. At this time, NC with the prefix "natural" is a good choice.

Post an NC, and you can also brag when you go out to a meeting.

Pseudo-big brother: "Haha, our research group likes to mention a sub-journal of "Nature" this year." (actually an NC)

True Big Brother A: "Congratulations, come and play when you have time." (I just published an article on "Science" last year)

True Big Brother B: "Boss, cooperation?"

Although others may think in their hearts, "What kind of publication, I don't say the name, it must be NC", but at least I won't lose face.

It can also be regarded as a chain of contempt. People who can post CNS main magazines or major sub-journals will think that NC is like that, but those who can’t even post NCs don’t even have the qualifications to be despised, and it’s hard to get into their circle. middle.

...

After the two discussed, Wei Xingsi looked at the time and said, "It should be past seven o'clock in Sweden. Let me contact Feng Shengdong." After speaking, he searched through his WeChat contacts and dialed a WeChat phone.

Xu Qiuxin said, today is Sunday, why don't you just call someone after 7 o'clock in the morning?

Unexpectedly, after more than 20 seconds, the call was really connected.

Wei Xingsi didn't shy away from Xu Qiu, and directly turned on the speakerphone.

"Hello, Teacher Wei?" Feng Shengdong took the initiative to say hello, speaking in Chinese, his voice sounded young, according to Xu Qiu's deduction, he was estimated to be in his thirties.

"Hey, Teacher Feng, I didn't bother you." Teacher Wei spoke softly.

"No, no, I just finished washing and I'm making breakfast for myself." Feng Shengdong's overall environment is relatively quiet. It should be at home or in the dormitory of the faculty and staff. He can vaguely hear the sound of a kettle boiling water on the receiver. .

"That's good." Wei Xingsi didn't chat too much, and went straight to the topic: "I just finished a group meeting for the students, and we have a job to do NC, which is Nat. Commun. That NC, you know, this journal The requirements for mechanism research are relatively high, and I mainly want to ask you to help me measure the data of TAS and TRPL, and then write some analysis and put it in the text.”

The main thing that needs to be tested by the other party is TAS. Through this test, the charge transport inside the blend film at the time scale of picosecond level can be clarified. As for TRPL, it is only incidental. After all, the samples required for the two tests are the same, except for white Never mind.

"Okay, no problem," Feng Shengdong's tone suddenly became brighter, "I still have a lot of time left on my machine recently, please send the samples as soon as possible, and I will test them for you personally."

Although Mr. Wei didn't say it in detail, but this level of help in the academic circle is basically equivalent to promising Feng Shengdong to be a corresponding author in the article. Of course, Feng Shengdong's boss Tnu may also come to share a piece of the pie, after all. The instruments and equipment are all under the name of Tnu, and if a student from the other side participates in the test, then the student will also be named as the author, but the ranking will not be too high.

"That's fine," Wei Xingsi also relaxed when he saw the other party agreeing, and further explained:

"Before I went to Sweden, the photoelectric conversion efficiency of the system made by my students was about 7.5%, and now it has broken through to 8.4%, breaking the world record in the field of PDI non-fullerene acceptors. The hope of impacting NC is very great, and The main body of the article has basically been written, but your research on the mechanism is missing, so I want to raise the quality of the work."

"Is it Xu Qiu, the student you told me about when you were here in the fourth year who sent out AMs as an undergraduate, right?" Feng Shengdong asked.

"That's right," Wei Xingsi said in surprise, "I just mentioned it casually at the time, but I didn't expect you to remember it."

"Of course, when I think about it, I didn't know where I was playing when I was a senior. I only published my first article in my second year of research. The current students are really better than the next generation." Feng Shengdong sighed with self-deprecation: "You See, I haven’t posted an AM until now.”

"What kind of AM are you doing theoretical research on physics? Aren't they all PR series?" Wei Xingsi paused and said, "By the way, he's right next to me now, Xu Qiu, say hello to Teacher Feng Shengdong. "

"Mr. Feng, hello." Xu Qiuke greeted politely. Feng Shengdong is an assistant professor. It sounds similar to a teaching assistant. In fact, he can supervise master students and doctoral students. You can transfer to other teaching positions, and you will still have the opportunity to obtain tenure if you work for a few more years and then evaluate as an associate professor.

"Hello, classmate Xu Qiu." Feng Shengdong also responded enthusiastically. Speaking of it, the two are really classmates, but there is a difference of many years.

Wei Xingsi interjected: "Xu Qiu, talk to Mr. Feng about the samples, this needs to be implemented as soon as possible, and send the samples over."

"Okay," Xu Qiu repeated his current writing ideas to Feng Shengdong: "A new type of 3D-PDI molecule has been developed, which involves three molecular structure optimization methods: three-dimensionalization, fused ring formation, and introduction of selenium atoms... ..."

During the narration, Feng Shengdong remained silent. Xu Qiu originally thought that the other party was listening carefully, until he saw a pop-up reminder on WeChat that "the current call signal is poor"...

Xu Qiu complained about the international line in his heart, "Hello" a few times, did not hear the response, hung up the phone and connected again, then he talked again from the middle where he left off, focusing on introducing the TRPL test related content.

Feng Shengdong is also more interested in this aspect, and said: "Let's add WeChat later, and you can send me the experimental results of TRPL."

"Okay," Xu Qiu agreed, and changed the subject, "If we want to prepare samples here, are there any requirements for sample preparation?"

"Hmm..." Feng Shengdong thought about it for a while, and said: "The substrate is made of quartz glass. The size does not need to be too large. A square of 1 square centimeter is fine. Also, the film must be uniform. Prepare three replicates for each system. The sample, the sample is vacuum-sealed and sent directly by courier. By the way, don’t forget to prepare a blank sample.”

"Quartz glass piece, 1 square centimeter in size, three replicate samples, blank sample, vacuum-sealed?" Xu Qiu said the key points he had just remembered in a rhetorical tone.

"That's right." Feng Shengdong said.

"What about the sample system, the three generations of 3D-PDI molecules, do we need to prepare separate components and blended films for each?" Xu Qiu and Feng Shengdong discussed, TAS is a relatively unfamiliar test method for him, he is very excited He wanted to copy Feng Shengdong's skills along the radio wave signal, but he couldn't.

However, this kind of theory-oriented skills is mainly copied from image data related to experimental operations, focusing on model construction and data analysis, and it is difficult to quickly develop them.

"Well, this idea is feasible. Individual and blended samples can be compared and analyzed intuitively, and the three generations of molecules can also be compared with each other." Feng Shengdong smiled and said: "If it doesn't work, you can use everything you can think of. Do all the samples, anyway, it’s always right to do more.”

"Okay." Xu Qiu had no problem, and turned to look at Teacher Wei.

Wei Xingsi had been listening in. Seeing that Xu Qiu and Feng Shengdong had basically reached an agreement, he didn't talk nonsense, and ended the topic directly: "Then let's do this for today, so you can have breakfast without delay. If there is any problem, the three of us will talk about it later."

"Okay, goodbye." Feng Shengdong said.

"Bye." Wei Xingsi took the initiative to hang up the phone, pushed Feng Shengdong's WeChat business card to Xu Qiu, and then said:

"You can add Mr. Feng's WeChat account later, you can chat with him if you have any questions, try to get the results as soon as possible, and submit the article."

Xu Qiu nodded in response, and sent a friend request to Feng Shengdong.

Wei Xingsi said suddenly: "I've worked hard on you during this time, I'll talk to Wu Feifei later to raise your monthly subsidy to the standard of a doctoral student."

"Thank you, Teacher Wei." Xu Qiu thanked him. Now that he has changed from one person to two, the expenses are indeed much higher. 'Could it be that Mr. Wei also knew about him and his junior, so he gave him more subsidies? '

"It should be, your current workload is stronger than that of several doctoral students in the group." Wei Xingsi smiled and said, "Okay, then you can go to work first."

Xu Qiu gave a "hmm", and returned to 216, Feng Shengdong had already approved his friend request.

Turning on the computer, Xu Qiu sent the TRPL data picture and the corresponding description part of the article to Feng Shengdong through the WeChat computer terminal. NC is very caring.

For the sample of transient optical absorption spectrum TAS, the substrate used is quartz glass. Compared with ordinary glass, quartz glass has high spectral transmission and can be used in spacecraft and spectrophotometer optical systems.

For example, in Teacher Wei’s laboratory, the cuvettes used to test the steady-state light absorption spectrum UV-vis of the solution are made of quartz glass. However, Xu Qiu’s main work is photovoltaic cell devices, and the solution test is relatively small, mostly for For the thin film test, the glass substrates used are all ordinary glass cut from glass slides.

Therefore, there is no quartz glass in the laboratory, and it needs to be obtained from the material department.

As soon as Xu Qiu walked out of room 216, he thought that the girls (old aunts) in the material department were on weekends, and today was Sunday, and the material department was closed, so he turned back and muttered: "Let's prepare the solution first. "

He glanced at Han Jiaying at the desk. The junior was busy writing an article. After noticing Xu Qiu's gaze, she raised her head and smiled at him.

Xu Qiu also responded with a smile, and walked into the laboratory by himself without disturbing her.

Chen Wanqing was coming out of the spin-coating glove box. When Xu Qiu was away, she found a sample of FTAZ and prepared a solution of FTAZ: IDT-ICIN, intending to try a wave of devices.

Xu Qiu quickly took over her position, feeling the residual warmth left by her senior, found her Lock Box in the glove box, and checked the stock of various materials.

The first, second and third generation 3D-PDI materials all have reserves of more than 100 mg.

There were a lot of materials, so Xu Qiu didn't save them, and prepared 1ml of solution for each system for use.

A total of seven systems, including three separate components of the 3D-PDI acceptor material, P3TEA, a separate component of the donor material that best matches the third-generation material, and three acceptor materials and the donor material blend solution.

Among them, although the best suitable donor material for the second-generation molecule is not P3TEA, but PCE10, but for data consistency, Xu Qiu uniformly replaced it with P3TEA.

After all, the third-generation molecules are the protagonists.

After preparing the solution, Xu Qiu returned to the desk again, thinking about what to do next.

Then, I realized that I didn't seem to have anything to do.

The article is basically finished, and the experiment can't be done now.

Xu Qiu waved his hands and started paddling.
