I Have a Research Support System

On Tuesday night, except for Duan Yun, Tian Qing, and Chen Wanqing, the other six people in the research team called a seven-seater car, took the prepared samples, and some food, and headed for the magic city light source together. test.

This time, two tests, GIWAXS and R-SoXS, need to be conducted at the same time.

On the way, the six people completed the division of labor. Sun Wo, Wu Feifei and Wu Shengnan were responsible for the GIWAXS test, while Xu Qiu, Han Jiaying and Mo Wenlin conducted the new R-SoXS test together.

Because the samples used in the two tests are the same, Xu Qiu divided the 138 samples into two. Wu Feifei and the others tested from the 1# sample to the 69# sample, and Xu Qiu and the others from the 138# sample to the 70# sample The samples are tested in reverse order. When either party finishes the test, exchange the samples in each other's hands.

Everyone arrived at the Magic City Light Source, and after completing the admission procedures, Xu Qiu first went to the user office building to submit the application materials for the R-SoXS project. At this time, it was close to nine o'clock in the evening, and the user office staff had already left work. , he delivered the paper materials to the mailbox.

Afterwards, everyone entered the main light source testing building. The R-SoXS test line station is BL12B1, which is not far from the GIWAXS test line station BL14B1 line station, and is closer to the gate.

When the three of Xu Qiu came to BL12B1, the group in front had already finished the test. The teacher on duty was a middle-aged man who looked about 35 years old, wearing casual clothes and black square glasses.

My name is Zhu Shangxing. You are the users who will be testing next. Is this your first time?

Xu Qiu responded with a smile: It's not the first time to come to Magic City Light Source, but it is indeed the first time here. Before that, we have been testing at the BL14B1 line station next door. It has been more than ten times. Then before the summer vacation we After reviewing comments on an article, one of the reviewers asked us to supplement the R-SoXS data, so we applied for an emergency time to come and test it.”

So that's the case, Zhu Shangxing nodded and asked, Are you doing organic photovoltaic?

That's right, they are indeed engaged in organic photovoltaics, Xu Qiu asked suspiciously, How did the teacher know?

Oh, our R-SoXS test line station has just been built not long ago. Among the people who come here to test, researchers in the field of organic photovoltaics account for the majority. After all, this is the only one in China and the only one in the world that can conduct R -The line station for the SoXS test, and the other is the advanced light source ALS of the beautiful country, which is also a new line station that our entire light source team spent more than three months building last year. After Zhu Shangxing finished blowing a wave, he laughed He smiled and said: Not much nonsense, let's debug, the specific test method...

Zhu Shangxing began to teach. The R-SoXS test method is similar to GIWAXS, but the energy of the X-rays used is different. This time the test uses soft X-rays with an energy of 284.8 electron volts.

In addition, the software used for data analysis is the same as GIWAXS, which is FIT2D, but the mode adopted is different.

Xu Qiu copied Zhu Shangxing's skills as usual, and the other party's proficiency reached 10% of the fifth level. It seems that teachers in this kind of research institute, if they specialize in an experiment, usually have a high level of proficiency.

After the commissioning was completed, Zhu Shangxing left a phone number and said, Call him directly if you have anything to do, and then left.

The three of Xu Qiu had a brief exchange and completed the division of labor.

Han Jiaying is in charge of operating the testing computer, Mo Wenlin is in charge of changing the samples, and Xu Qiu is in charge of processing the data, rotating every 20 samples.

R-SoXS mainly characterizes the phase separation morphology in the effective layer, including the purity of the phase, the scale of the aggregated phase, etc. The obtained data is not like a two-dimensional color map of GIWAXS, but a smooth curve with peaks and mountains .

Xu Qiu performs data processing and data analysis in real time, and he is most concerned about the J2:IDIC-4F system.

The results show that the phase purity of this system is relatively high, and the relative purity is 1:0.95, which is a very high value, which can effectively prevent the separated charges from being recombined during transport, and is conducive to achieving high device efficiency.

In addition, the phase domain scale of the aggregation phase is about 30 nanometers, which is higher than the 10-20 nanometers of the conventional high-efficiency fullerene derivative organic photovoltaic system, which can echo the higher exciton diffusion distance of IDIC-4F .

It is more comfortable to get these two results.

Because they can be compared with the results of other test representations, it makes Xu Qiu's work more solid, and the probability of the article being accepted is higher.

When doing a job, it is usually necessary to carry out more than a dozen or twenty kinds of characterization tests. If such conclusions can be confirmed by each other, it is naturally excellent, but in the actual experimental process, contradictions are inevitable.

This is also the situation that every scientific research worker is most afraid of. After a lot of hard work, the conclusions obtained from different characterization tests eventually point to the opposite result.

In this case, there are generally three approaches.

The worst strategy is to directly change the data. This kind of academic fraud may not be recognized by the editors and reviewers when the article was submitted, and the article will be published. Real hammer, basically this person's academic path will come to an end;

The best strategy is to list this data in the text, but this is easy to be discovered by the reviewers. If the reviewers want your article to pass, they may ignore it, or ask you to explain it. This is not bad, but If the other party does not want your article to pass, there is a high probability that they will use this to hang up your article and hammer it, and you can only accept the hammer because the other party did not make a mistake;

The best strategy is to simply hide this data, or put it in the supporting information. In this way, the risk of being caught is relatively small, but relatively speaking, the workload will be reduced by a little bit.

The medium policy and the best policy here are only from the perspective of publishing articles. In fact, burying the problem and pretending to be an ostrich is obviously not the mentality that a qualified scientific researcher should have.

Therefore, there is a fourth approach, which is the best policy.

Based on the current contradictions, a convincing new theory is deduced.

Well, the difficulty can be imagined. For most people, it is basically an option that does not exist.

Therefore, many people choose C.

This time the light source test went smoothly, and the progress of GIWAXS was a little faster. After all, the old experiment was more proficient, and the number of samples was less than that of R-SoXS.

In the end, everyone was busy until four o'clock in the morning, and finally completed the test of all the samples, and took a taxi back to the school together. By the way, they also had an early lunch next to the gate of the dormitory in the North District.

I have to say that it is really hard for those who specialize in breakfast. They need to start preparations at three or four o'clock, steaming steamed buns, steamed buns, making soy milk, etc., after two hours of hard work, business will come around five o'clock, and then Still have to work for another three or four hours.

Of course, the early shops that can continue to open generally have good income, and it is not too difficult to earn 10,000 to 20,000 a month in Shanghai.

Including the Dark Cuisine, which was cracked down before, was caught by the urban management and paid a fine of 500, which may only be the money they earn in a day.

A small business is not like a part-time job, self-employed basically does not pay taxes, and there is no middleman (boss, country) to make the difference.

When Xu Qiu returned to the dormitory, it was already half past five in the morning.

Xing Lin, a roommate in bedroom C next door, has just woken up. When he was washing in the bathroom, he saw Xu Qiu coming back from the door. He was stunned for a moment and asked, Did you go to exercise early?.

Xu Qiu casually explained: I just came back from an overnight experiment.

Xing Lin just gave a thumbs up and cast a look of admiration: Boss, amazing!

Xu Qiu waved his hand, walked lightly into his room A, lay down and fell asleep.

When I woke up again, it was already one o'clock in the afternoon.

Xu Qiu stretched his waist and ordered a takeaway. If he went to the cafeteria now, he would hardly be able to eat anything.

Staying up all night is quite tiring, mainly because it disrupts the biological clock.

If you have been sleeping during the day to form a habit, in fact, the impact will not be great.

Xu Qiu didn't believe popular science articles such as How to detoxify the liver and how to detoxify the kidney that were reposted in the circle of friends and the group chats of Love each other as a family.

A very simple reason, the night in the beautiful country roughly corresponds to the daytime of the flower growers. Is it true that the internal organs of the beautiful country are detoxified during the day.

Moreover, even if this theory of detoxification is correct, it should be that the detoxification time should follow the schedule. Why do billions of people detoxify according to the same time? This makes no sense.

Xu Qiu thinks that in theory, as long as you ensure regular work and rest, enough sleep time, and accurate perception of time to keep your biological clock running stably, there is actually no big difference whether you sleep during the day or at night.

Of course, in fact, there is still a difference between sleeping during the day and at night. During the day, there will be factors such as noise and light that affect the quality of sleep, which makes the quality of sleeping during the day not high enough.

Therefore, the root cause of staying up late for a long time to hurt the body should be low sleep quality, and the difference in sleep time is just a superficial appearance.

On Wednesday, Xu Qiu stayed in the dormitory for a whole day, supplemented the two data of the light source in the AM article of the IDIC system, and completed the final version of the draft paper.

Then continue to write another article on the IDIC-4F system, which is the one aimed at Natural·Energy.

So far, the experimental data of this system has been completed. The progress of the article is really not fast. It is almost 30% to 40%. After that, the text and pictures will be polished, but it should be able to be submitted before the National Day.

PS: In fact, the R-SoXS test cannot be carried out by the Shanghai Light Source in China, and the ALS in the beautiful country is the only laboratory in the world that can carry out this test. In addition, the sample preparation for this test is very troublesome. The sample preparation process is similar to that of TEM, where the polymer film is floated on the water surface, and then silicon nitride is used as a support to remove the film. The silicon nitride support cannot be produced in China and can only be imported. The cost is also high. But because I didn’t check the data carefully when I mentioned this experiment, now in order to avoid bugs in the plot, I changed this experiment to another GIWAXS test with the same test conditions as the light source, including the test site BL12B1 line station , using a line station name that does not exist in reality.
