Chapter 377: No middleman makes the difference

On Tuesday night, six other people in the research team except Duan Yun, Tian Qing and Chen Wanqing called a seven-seater special car, brought the prepared samples and some food, and went to the Magic City Light Source together. test.
This time, both GIWAXS and R-SoXS tests need to be performed at the same time.
On the road, the six people completed the division of labor. Sun Wo, Wu Feifei and Wu Shengnan were in charge of the GIWAXS test, and Xu Qiu, Han Jiaying and Mo Wenlin performed 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 went from 1# sample to 69# sample for positive sequence testing, and Xu Qiu and others started from 138# sample to 70#. The samples are tested in reverse order, and when either party finishes the test, exchange the samples in each other's hands.
After everyone arrived at the Magic City Light Source and completed the admission procedures, Xu Qiu first went to the user office building to submit the application materials for the R-SoXS project. This time, it was close to nine o'clock in the evening, and the staff of the user office were naturally off work. , He delivered the paper materials to the mailbox.
Afterwards, everyone entered the main building of the light source test. The R-SoXS test line was at BL12B1, not far from the BL14B1 line where the GIWAXS experiment was tested, and closer to the gate.
When Xu Qiu and the three came to BL12B1, the previous group of people had already tested. The teacher on duty was a middle-aged male, who looked about 35 years old, dressed in casual clothes and black square glasses.
"My name is Zhu Shangxing. Are you the users who will be testing next? Is this your first time?"
Xu Qiu responded with a smile:
It’s not the first time that the Magic City Light Source has come, but it is indeed the first time. We have been testing at the BL14B1 line station next door. After reviewing comments for an article from, a reviewer asked us to add R-SoXS data, so he applied for an emergency machine and came over for testing."
"It turned out to be like this," Zhu Shangxing nodded and asked, "You do organic photovoltaics?"
"Yes, it does make organic photovoltaics," Xu Qiu asked in confusion, "How did the teacher know?"
"Oh, our R-SoXS test line station has just been built just now. Among those who come here for testing, researchers in the field of organic photovoltaics are the majority. After all, this is the only one in China, and the only two in the world that can perform R -The line station tested by SoXS, and the other is the advanced light source ALS of Beautiful Country. This is also the new line station that our entire light source team took more than three months to build last year." Zhu Shangxing laughed after blowing a wave. He said with a smile: "Don't talk nonsense, let's debug, the specific test method..."
Zhu Shangxing started teaching. The R-SoXS test method is similar to GIWAXS, except that the energy of the X-ray used is different. This time the test uses soft X-rays with an energy of 284.8 eV.
In addition, the software used for data analysis is the same as GIWAXS, FIT2D, but the model is different.
Xu Qiu copied Zhu Shangxing's skills as usual, and the other party's proficiency reached 10% of Tier 5. It seems that if teachers in such institutes specialize in an experiment, their proficiency is usually not low.
After the commissioning was completed, Zhu Shangxing left a phone call, saying "Call him if you have something to do", and then left.
The three of Xu Qiu exchanged briefly and completed the division of labor.
Han Jiaying is responsible for operating the test computer, Mo Wenlin is responsible for changing the samples, and Xu Qiu is responsible for processing the data, rotating every 20 samples tested.
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 data obtained is not like GIWAXS, which is a two-dimensional color image, but a smooth curve like ridges. .
Xu Qiu conducts 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 split charge from being recombined during transport, which is beneficial to realize the high efficiency of the device.
In addition, the phase size of the aggregate 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 correspond to IDIC-4F's higher exciton diffusion distance. .
It is more comfortable to get these two results.
Because they can correspond to the results of other test characterizations, Xu Qiu's work is 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 two kinds of characterization tests. If this kind of conclusion can be mutually confirmed, it is naturally excellent, but in the actual experiment process, conflicts are inevitable.
This is also the situation that every scientific researcher is most afraid of. After a lot of hard work, the results of different characterization tests led to the opposite result.
At this time, there are generally three approaches.
The next policy is to directly modify the data. This is academic fraud. It may not be visible to the editors and reviewers when the article was submitted, and the article was published. But the night is gone, and sooner or later it will be cool, even if it is just a fraud. Real hammer, basically this person's academic path has come to an end;
The central strategy is to list this data in the main text, but this is easy to be found by reviewers. If the other party wants your article to pass, they may ignore it or ask you to explain it. This is not bad. If the other party does not want your article to pass, there is a high probability that you will use this point to hammer your article, and you can only receive the hammer because the other party did not make a mistake;
The best strategy is to hide this data altogether or put it in supporting information. In this case, the risk of getting caught is relatively small, but the workload will be reduced by a relatively small loss.
The middle policy and the best policy here are only from the perspective of article publication. 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 derived.
Well, the difficulty can be imagined. For most people, it is basically an option that does not exist.
Therefore, many people chose C.
The light source test this time was fairly smooth, and the progress on GIWAXS was a bit faster. After all, the old experiment is more proficient, and the number of samples is less than that of R-SoXS.
In the end, everyone was busy until four o'clock in the morning, and finally completed the testing of all samples, and took a taxi back to the school together. By the way, they stayed early next to the school gate in the North District dormitory.
I have to say that it’s really hard to make early breakfasts. They need to start preparing at three or four o’clock, steaming steamed buns, steaming buns, and making soy milk. They work for two hours. By five o’clock, business is almost there. It will continue to work for another three or four hours.
Of course, the income of the early shops that can be opened is generally good, and it is not too difficult to make a monthly income of 10,000 to 20,000 in the city.
Including the dark food that was hit before, and was caught by the city management and paid a fine of 500, it may be just the money people make in a day.
Small business is not like working for people, self-employed, basically not paying taxes, no middlemen (boss, country) to make the difference.
When Xu Qiu returned to the bedroom, it was already five thirty in the morning.
Xing Lingang, a roommate in bedroom C next door, had already got up. When he was washing in the bathroom, he saw Xu Qiu coming back from the door. He was taken aback for a moment and asked, "You went to exercise early?".
Xu Qiu casually explained: "I just came back from the experiment all night."
Xing Lingang gave a thumbs up and cast an admiring look: "Big brother, awesome!"
Xu Qiu waved his hand, gently entered his room A, lay down and fell asleep.
Woke up again, it was already one o'clock in the afternoon.
Xu Qiu stretched out and ordered a takeaway. Now when he goes to the cafeteria, he can hardly eat anything.
The whole night is quite tiring, mainly because it disrupts the biological clock.
If you have been sleeping during the day to form a habit, the effect will actually be small.
Xu Qiu doesn't believe in popular science articles like "How many liver detoxifications and kidney detoxification" forwarded in the circle of friends and the group chat of "Dear and love each other."
A very simple reason is that the night of the beautiful country corresponds roughly to the day of the flower planter. Is it that the organs of the beautiful country detox during the day?
Moreover, even if this set of detoxification theory is correct, it should be the time for detoxification to follow your schedule. Why do billions of people detoxify according to a period of time? There is no such reason.
Xu Qiu believes that in theory, as long as you ensure a regular schedule, sufficient sleep duration, and accurate perception of time, UU reading www.uukanshu.com makes the biological clock run stably. There is actually not much difference between sleeping during the day and sleeping at night.
Of course, in fact, there is still a difference between sleeping during the day and night. During the day, there will be noise and light that affect the quality of sleep, which makes the quality of sleep during the day not high enough.
Therefore, the fundamental reason for staying up late and hurting the body should be low quality of sleep, and the difference in sleep time period is just appearance.
On Wednesday, Xu Qiu stayed in the bedroom for a day, supplementing 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 target "Nature·Energy".
So far, the experimental data of this system has also been supplemented. The progress of the article is really slow. It is almost 30-40%. After that, the text and pictures will be polished, but it should be possible to vote before the National Day.
PS: Actually, the domestic Magic City Light Source cannot carry out R-SoXS test, and ALS of 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. The polymer film is floated on the water, and then silicon nitride is used as a stent to fish the film. Silicon nitride stents cannot be produced in China and can only be imported. The cost is also high. But because I didn’t check the information carefully when I mentioned this experiment, now in order to avoid the BUG 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.
