I Have a Research Support System

Monday group meeting.

Wu Feifei's article on "Lead Thiocyanate Additive" has been completed.

Originally, she planned to vote on Sunday, but yesterday Chen Wanqing moved a step faster and found Teacher Wei in advance.

Then, Mr. Wei revised the article until night. After all, he was in his forties, not like a young man in his twenties.

After a day of hard work, my energy has been exhausted, and finally I can only put Wu Feifei's article on Monday for revision.

Wu Feifei's work is intended to be submitted to Chem. Comm., referred to as CC.

CC is a second district journal under RSC. Although the impact factor is only about 6, the level of the journal is still good.

It is relatively biased towards the direction of chemistry, the length is short, and the review is fast. It is regarded as a lower-level journal of JACS and German Yinghua.

In the process of reading the literature, Xu Qiu found that in the field of organic photovoltaics, there are not many articles published in the journal CC.

Therefore, when he wrote the article before, he did not consider submitting to this post.

After all, no matter what causes this phenomenon is unspoken rules or other reasons, when an old journal does not receive many manuscripts in a certain field, it is better not to be stubborn.

If it is a new journal, it may also be because of its low popularity, or researchers worry that it does not have divisions, etc.

If you submit an article and choose a journal with a large number of manuscripts in the relevant field, the probability of the article being published will increase a lot.

In addition, after listening to the report for nearly a semester, Xu Qiu has almost grasped the routines in the field of perovskite photovoltaics.

He feels "I can do it if I go up".

The materials are all ready-made, bought and mixed, then painted, then steamed, and finally tested.

High efficiency, supplement other data, organize data, and publish articles.

The efficiency is not high, see if it can be optimized higher, if it can, add data and post an article, if not, change to another system, and cycle again.

However, he just thought about it.

Now, he has seniors on the left and juniors on the right, and he is really reluctant to leave.

Duan Yun's work has also improved, and Teacher Wei rarely smiled at him.

From the tone of his chat with Mr. Wei, Xu Qiu can roughly infer that his job is not capable of publishing big articles, and he is probably at the end of the crane in the second district, at the ACSAMI level.

But no matter what, it's just a piece of work. If it is successfully published, Duan Yun will be one step closer to graduation.

He doped n-type and p-type bismuth telluride powders in the commercial PH1000, and the prepared thermoelectric materials exhibited high power factors, up to 70 and 40 microwatts per meter per square Kelvin, respectively.

Like the photoelectric conversion efficiency in the photovoltaic field, an important indicator for evaluating the quality of materials in the thermoelectric field is the power factor.

Of course, the higher the power factor, the better.

However, since there is currently no uniform standard for its measurement methods in the world, unlike the photovoltaic field where standard silicon cells can be used for calibration, resulting in the same experimental conditions in the thermoelectric field, the values ​​measured by different research groups may vary greatly.

Therefore, in the field of thermoelectricity, the data in the same order of magnitude are generally considered to have little difference.

It is also difficult to set a threshold with the absolute value of a physical quantity like in the field of photovoltaics.

For example, in the field of organic photovoltaics, an efficiency of 10% is a big threshold, but in the field of thermoelectricity, it cannot be compared. If the power factor is set to exceed XX, it is a zone.

At this time, if the thermoelectric field wants to publish a big article, in addition to the solid experimental data itself, it must also tell the story well, which is a test of the author's writing skills.

After Duan Yun finished, Wei Xingsi asked:

"Tian Qing, do you have anything to say?"

"No, I was writing an article last week, and I can almost finish it this week."

"Chen Wanqing, what about you?"

"No."

"Xu Qiu?"

"No."

Three "no" in a row, including Wu Feifei who only said a few words at the beginning, only Duan Yun said more.

The main reason is that recently the small partners in the research group have been concentrating on writing articles.

Although Xu Qiu has experimental data, he doesn't need to talk about it himself.

In the past two weeks, Han Jiaying basically reported the results of the organic experiment in the group, which was also "exercising" her ability.

"Han Jiaying?"

"Yes, I have."

The school girl hurriedly responded, gave up her seat and got up and inserted the USB flash drive into the large computer in the office.

Her report consists of two parts.

Part of it is her own work, and she is still in the stage of optimizing device performance, making about two batches of devices every week.

Currently, her two systems have the highest efficiencies of 6.27% and 6.74%, respectively.

If he works harder, there is a certain possibility that he can reach the goal that Xu Qiu set for him, 6% and 7%, and there is hope.

The other part was the work Xu Qiu arranged for her, which was to help him with supplementary experiments.

Judging from the current progress, the data can be completely completed after the light source ends this week.

Moreover, there are only four experimental data missing, so there is no need to rush too much. Maybe I can paddle properly this week.

During the report, Teacher Wei asked:

"What is the molecular weight of the P3T material, roughly how much, is it high?"

"Probably..." Han Jiaying couldn't answer, and looked at Xu Qiu for help.

"This is newly synthesized. GPC has not been tested yet, but judging from the product shape, yield, and post-treatment process, the number average molecular weight should not be lower than 20,000." Xu Qiu said.

"Well, let's test the GPC when you have time."

"good."

Although there should be no time to test this week, Xu Qiu still agreed first.

Anyway, when the group meeting is held next week, Teacher Wei will probably forget about it.

In fact, this is also the habit left by Mr. Wei in his early scientific research. When he was doing synthesis, after getting the polymer, he likes to go through the NMR, GPC and other characterizations first.

...

After the group meeting, Chen Wanqing approached Xu Qiu and asked, "Are you free?"

"What's the matter?" Xu Qiu asked suspiciously.

"I want to discuss with you about my future work." Chen Wanqing said.

"Isn't your new job just to test the light absorption spectra of P4T-2OD materials under different temperature treatment conditions?" Xu Qiu said.

"But wouldn't such data be a little thin?" Chen Wanqing said.

"The highlight is this unique experimental phenomenon. A unique characteristic that is different from the traditional system has been discovered in high-performance materials. I think it is enough to post a small article in the second district."

Xu Qiu thought for a while and said casually:

"In addition to measuring the thin film, then measure the solution at different temperatures?"

"Yes, this idea is feasible." Chen Wanqing took a note, and then asked expectantly:

"Student, do you have any other ideas?"

Xu Qiu stared at her for a while, the senior sister looked at him without blushing.

I was really afraid of you, Xu Qiu had no choice but to turn his eyes away, and after thinking for a moment, the "senior sister style" inspiration spewed out:

"It can be assisted by TEM, and P4T of different side chains can also be studied. Even if you want, P3T and P5T are all possible..."

Thanks to ytp121, this damn novel wasted my youth and rewarded 100 starting coins.
