I Have a Research Support System

On Friday, the transportation list of hazardous chemicals submitted by Xu Qiu has been reviewed and approved by the department, and the transportation is approved.

It's one o'clock in the afternoon next Tuesday.

The matter at hand was basically dealt with, and Xu Qiu continued to carry out scientific research work, aiming at the two tasks previously entrusted to Chen Wanqing and Han Jiaying, which were "full solution, colorful, translucent devices" and "scratch-coated devices under the standard system". ".

Both of these works are expected to be published in AM-level top journals.

Among them, the work of the junior sister started slower than that of the senior sister, but the progress at this stage is faster than that of the senior sister. The device efficiency has reached more than 10%, and you can start writing articles.

In terms of thinking, it is similar to the AM article on translucent devices written by Xu Qiu before. It does not involve the synthesis of new materials, so it is necessary to look for bright spots from other places. "Scratch coating" is one bright spot, and Xu Qiu plans to choose "stability".

In this way, the five pictures in the article almost correspond to each other: the molecular structure and light absorption performance of the material, the exploration of the molecular stacking structure of the effective layer film by means of GIWAXS, etc., the observation of the morphology of the effective layer blend film by electron microscope TEM and AFM, and the J-V curve , The EQE curve characterizes the photoelectric performance of the device, and the storage stability of the device for a long time.

In addition, the senior sister's work efficiency has reached 7%. Xu Qiu is going to let her continue to optimize the processing technology to see if she can go one step further and reach more than 8%. This will be more secure and the articles that hit the AM level will be more confident Some.

At the same time, Xu Qiu took stock of the articles in his hand.

He found that the number of officially accepted articles in District 1 has reached seven, including three AM articles, two AEM articles, one NC article, one Angew article, and one ACSEL that has not been released yet but is expected to be evaluated in District 1. If so, it is eight chapters and one district.

In addition, there are three articles in the first district that are being submitted, namely "High-efficiency non-fullerene semi-transparent devices" submitted to AM, and "IDIC-4F with a breakthrough efficiency of 13.5%" submitted to "Nature Science". Systems", and "A review of ITIC non-fullerenes" in Joule.

It is very close to completing the system advanced task of "publishing ten articles in one area and one author".

Judging from the articles published by Xu Qiu, the high-end articles are mainly concentrated in AM and AEM.

This is also normal. After all, in the field of organic photovoltaics, the most suitable journals are Advanced Materials (AM) and its sub-journals AEM and AFM under Wiley.

The rate of successful drafts is high, and naturally there will be more submissions.

Each journal has a different acceptance situation for different fields. There is no need to force yourself to increase the difficulty. You must pursue complete averages, as long as they are not all concentrated in a single journal.

Like the 250 non-review articles in the field of organic photovoltaics that Xu Qiu counted in recent years, the specific distribution is as follows:

"Nature" is a major sub-journal level, "Nature Materials" has 1 article, and "Joule" has 2 articles.

There are 32 papers in AM, 15 in JACS, 8 in Nano Energy, 8 in EES, 5 in NC, and 4 in Angew.

There are 27 papers in AEM, 13 papers in AFM, 5 papers in ACSEL, and 4 papers in Adv.Sci.

At the second district/weak first district level, JMCA has 46 papers, ACSAMI has 35 papers, CM has 14 papers, "Macromolecules" has 9 papers, JPCL has 6 papers, Small has 6 papers, CC has 4 papers, and JPCC has 4 papers , Nanoscale has 2 articles.

The division of specific journal levels has Xu Qiu's subjective elements in it, but overall it will not deviate too much.

"Joule" has the potential to reach the level of a major sub-journal of "Nature", but it is a new journal after all, and it is still in the growth stage. Nature" major sub-journal level.

The top journal in a district is the journal with the highest influence in the corresponding field. The four major journal companies ACS, RSC, Wiley, and Elsevier generally have only one journal in the same field that can be called a top journal, and Wiley is somewhat special. , AM and Angew are classified as top journals in the first district, because AM is related to materials, and Angew is related to chemistry.

Ordinary District 1 refers to journals with large and small categories, but they are not the top journals in this field, just like AEM and AFM. The influence is not low, but they are sub-journals of AM after all, so they are classified as ordinary journals. The first district, and although ACSEL has the potential to become a top journal in the first district, its current influence is not enough, and it is also classified as an ordinary first district.

The weak first zone refers to the kind of journals whose grades repeatedly jump between the first zone and the second zone, such as those in the first zone of the major category and the second zone of the small category.

Speaking of this, basically all the journals in the field of organic photovoltaics belong to the weaker region, and the material-related subcategories are all in the second region. The calculation of the scholarship is based on the second region, which is very disadvantageous.

Otherwise, if JMCA and ACSAMI are counted as one area, then Xu Qiu and the others can write articles at will. Every year, they publish five JMCA and ACSAMI articles, and they can win national awards every year.

The documents in the group were checked by Wei Xingsi manually, and there must be some fish that slipped through the net and were not included in the statistics.

However, Xu Qiu estimates that at least 80% or even more than 90% of the articles related to the field of organic photovoltaics in the first and second districts have been counted, and the statistical results are relatively reliable.

It can be clearly seen that among the top journal-level articles in the field of organic photovoltaics, AM publishes more articles, which is almost the same as the combined number of other top journals in the first district.

In addition, the field of organic photovoltaics has not published articles of the type of "scientific research work" at the level of the main journal of CNS for a long time.

The main reason is that the development of organic photovoltaics has been very slow in the past few years. Since PCE10 was developed, there has been no breakthrough.

However, if it is a non-"scientific research" article, such as Perspectives (viewpoint), Letter (letter), News (news) type of article, the bosses can still often post it on CNS, that is, there are only one or two pages The kind on the page, go up and talk about some of their opinions.

This is also the privilege of a big boss.

For example: "Getting Moore from Solar Cells" ("Do solar cells also follow Moore's Law?" Citation: Science 2012, 338, 625-626.)

“Outlook Brightens for Plastic Solar Cells” (“Outlook Brightens for Plastic Solar Cells”, Cited: Science 2012, 335, 162.)

Of course, things are different now.

Following Xu Zhenghong's previous article "Nature·Materials", and Xu Qiu leading Wei Xingsi's research group to continuously publish articles on AM, the popularity of organic photovoltaics has begun to pick up slowly.

Xu Qiu still has two articles at the level of a major sub-journal of "Nature" on the way.

In the evening, Xu Qiu and Han Jiaying continued to help Duan Yun take the online test. These days, they helped Duan Yun participate in the first round of online assessments of many companies.

The topics of the test were similar to those of Exxon Mobil before. During this process, Xu Qiu also learned about the recruitment situation of some companies.

Familiar large companies like Dow Chemical, ExxonMobil, and Warwick have a relatively templated recruitment process, and their wages are relatively standard.

Duan Yun learned from his brothers and sisters at Warwick from the Department of Materials Science and Technology of Shanghai Comprehensive University in previous years that the Ph.

Some little-known "small factories" will pay higher wages instead.

For example, a company in Shencheng that makes organic light-emitting diodes (OLEDs) is said to have very strong capital behind it, and the price is very high. The monthly salary is 30-40K, and there are tens of W of settling expenses, bound to a five-year agreement.

The corresponding threshold is also very high. It is said that 985 doctoral students start. In fact, the main recruiters are recruited from several C9 universities or 985 ranked in the top 20.

The monthly salary of a Ph.D. can be 30-40K, which is already very high in science and engineering.

Although this price is still incomparable with the big companies in the financial IT industry, the same level of conditions, in the financial IT industry, the salary may be doubled, but there is no way, who makes the materials professional in Tiankeng.

Of course, the competitive pressure and work intensity of financial IT may also be stronger, after all, it takes a lot of money.

Having said that, according to Duan Yun's situation, even if he got an offer from this Shencheng OLED company, he might not necessarily go there.

Because his hometown is in Taicheng, Zhejiang Province, and there are still girls waiting for him. After graduation, he is probably planning to get married.

If Duan Yun stayed in Shanghai or developed in the Yangtze River Delta, it would be relatively close, and it would be very convenient to go home by high-speed rail, but if he was going to Shencheng, it would be a little far away, and he would still be bound for five years.

If she really went, the girl would probably run away with other people in a few years.

Saturday afternoon, bedroom.

Because Han Jiaying went back to Sioux City this week, Xu Qiu didn't go out for a while, but chose to rest in the dormitory and read novels in bed.

Sun Yifan was also in the dormitory, rubbing the hearthstone in front of the computer, when he suddenly said, "Xu Qiu, are you free tonight? I'll treat you to dinner."

"Yes, I'm free." Xu Qiu nodded in response, and then asked, "Is there anything you want?"

"Hmm..." Sun Yifan looked hesitant: "It's nothing, it's just a meal, and it's been so long since we haven't gotten together."

"Okay." Seeing this, Xu Qiu didn't continue to ask. He kept guessing Sun Yifan's intentions in his mind, but after thinking about it for a long time, he couldn't think of anything.

Usually, I didn't see anything unusual about Sun Yifan, so I simply stopped thinking about it. Anyway, if there was something wrong, I would know it when I was eating.

Xu Qiu and Sun Yifan are not the kind of extroverted people, so they are usually busy with each other in the dormitory, and generally do not communicate too much.

Most of the science and engineering students are also the type of Xu Qiu and Sun Yifan. The type of extensive communication like Tao Yan is still a minority in the group of science and engineering students.

Especially after being promoted to a graduate student, although everyone is a classmate in name, the relationship between graduate students who are not in the same research group is more like employees of different companies in the same office building.

We may say hello when we meet in normal times, but it’s just a nodding acquaintance. It’s hard to have too many deep acquaintances.

Take the class group for example. Except for the counselors notifying about class matters such as scholarships and physical examinations, generally few people take the initiative to chat in the class group.

PS: Today is the third watch, asking for monthly tickets and recommendation tickets.
