Chapter 175: Get it done, call it a day

"I have a scientific research support system ( to find the latest chapter!
The previous four questions all asked Xu Qiu to make corresponding changes in the article.
In addition, there are some other questions, no need to modify the text, just answer them in the reply letter.
For example, a reviewer asked: "What is the solubility of this material in conventional solvents?"
Xu Qiu remembers that in the text, he has related introductions about the dissolution properties of materials.
He looked for it, and as expected, in the material synthesis part of the text, he wrote: "P2FBT4T-2OD material has excellent solubility in chloroform, chlorobenzene, dichlorobenzene and other solvents."
Questions of this kind have little value.
The reviewer asked it, and it is very likely that he did not notice the details in the article.
But I can't beat them. Xu Qiu first thanked the other party for their comments, and then quoted the corresponding original text in the article in the reply letter.
...
After dealing with the comments of reviewers, there are also the most efficient updates, and the issue of material renaming. It is also necessary to explain.
Xu Qiu wrote these two points directly at the top of the reply letter to inform the editor:
"During our article submission period, the maximum efficiency of the device was further improved to 88.88% (highlighted), and we decided to name the material P2FBT4T-2OD PCE11."
He hadn't measured the specific value of efficiency in reality, so he simply filled in one at random, highlighted it, and changed it later.
Of course, the text of the corresponding article will also be changed, but he has no plans to change it.
He is going to list the devices to be made today, that is, the efficiency data expected to exceed 11%.
That is to add a new line to the original photoelectric performance parameter table, and fill in the highest efficiency.
At the same time, the statement is the highest result obtained in a single experiment after submission, so there is no need for repeated experiments.
After all, according to AM's requirements, it is difficult to repeat five or more batches of devices in a short time, unless an analog laboratory is used.
But Xu Qiu is more cautious. He thinks it is better to make a clear distinction between simulation and reality. He does not want to use the experimental data obtained in the simulation laboratory directly into reality.
Because you use it once, you will use it a second time.
Too much of this kind of thing, there will be potential risks in the future.
If someone finds an abnormality, explain it, you can't say the experiment you did in your dream.
As for the change of the material name, it is also more troublesome. The main text, diagrams and the like must be changed accordingly and unified into PCE11.
He changed all the parts that could be changed, and highlighted the ones that could not be changed.
...
After roughly writing the reply, Xu Qiu looked at the time and talked with Chen Wanqing about ten minutes before the annealing.
"Senior sister, how about it? After reading the reviewer's comments, do you have any feelings."
"This AM is stable. The comments you received are all very easy to change, and there is also a suggestion in it for direct publication." Chen Wanqing envied: "Think of the articles I voted. They are all ill-fated. "
"Yeah," Xu Qiu touched his head and said with a smile:
"By the way, it's the first time I have seen it. The reviewer comments request to supplement the description of the experimental operation part."
"Hmm..." Chen Wanqing thought for a moment, and said, "Most of them want to do similar research. How did you write the experimental operation part?"
"I just wrote down the entire experiment process, but the specific details, such as spraying and heating the substrate, etc., did not go into detail," Xu Qiu finished, adding:
"I think other people wrote like this."
"Hmm, this is normal," Chen Wanqing nodded:
"If you want to describe the entire experiment process in words, it is not realistic. You can write it in your own way, and be as detailed as possible. If someone is really interested, you will email us to ask later."
"I will still send an email to ask? Has the senior sister ever encountered such a situation?" Xu Qiu asked in surprise.
"Yes, I have experienced it." Chen Wanqing licked her hair and began to mutter:
"I was doing electrospinning during my master's degree. At that time, I saw a document posted on JMCA. I found it inspiring and wanted to imitate their experiment.
But the other party concealed the content of a key additive, and only said a small amount. I tried to guess a few of the content myself, but I couldn't spin the fiber with a diameter of 200 nanometers as they said.
Later, I went to my supervisor and he told me, ‘If other researchers have any questions about an article published in an academic journal, they can directly contact the corresponding author of the article, and in most cases they will reply.’
So, I read that the article was published by a domestic research institute, and I sent an email directly to their corresponding author. "
"What happened later?" Xu Qiu asked.
"Later, I received a reply the same day," Chen Wanqing said:
"Their corresponding author, the big boss in the group, forwarded the email to a small boss in the group, and the small boss forwarded it to a student, probably the first author of this article.
In the end, the student replied to me, saying that their addition amount is 1% quality score. "
"Did the senior sister repeat it last?" Xu Qiu asked.
"No." Chen Wanqing spread her hands helplessly.
"Ah, why?" Xu Qiu asked curiously.
"Because of the 1% condition, I tried it once before sending the letter. I didn't succeed. I tried it again after receiving the reply, but it still didn't work." Chen Wanqing said.
"This..." Xu Qiu said.
The senior sister sighed lightly and said with emotion:
"There has always been a set of sayings in the academic circle, experimental-type articles, researchers themselves do not believe in what they have made, but others who read it do.
For theoretical articles, researchers usually believe in their theories, but others always feel that this theory is flawed everywhere. "
Xu Qiu was speechless.
However, thinking about it carefully, what the senior sister said seems quite reasonable.
After a while, the direction of the laboratory suddenly heard a slight "Didi" sound.
Then, the sound stopped and he heard Han Jiaying's call:
"Brother, the annealing time for zinc oxide is up. I have pressed the stopwatch for you."
"Come, here." Xu Qiu hurriedly responded, and then walked quickly into the laboratory.
Han Jiaying is standing next to the ultrasonic cleaner, processing the monocrystalline silicon wafer used for the light source sample substrate. At present, the wafer has been cut into small pieces and is preparing for the cleaning operation.
Xu Qiu remembered the results of his hard work in the simulation laboratory last night, and said:
"School girl, today I will make a device. By the way, help your system and optimize the experimental conditions."
Han Jiaying stayed for a while, then smiled sweetly and said, "Thank you brother, do you need my help?"
"No, you can concentrate on preparing light source samples." Xu Qiu waved his hand and said.
He suddenly realized that this seemed to be the first time he offered to help her conduct experiments in addition to teaching experiments, and it was usually the other way around.
Mindful of this, Xu Qiu felt that the squeeze on school girls seemed a little bit cruel in the past few months.
I'll treat her better after that...probably?
...
The zinc oxide substrate is annealed in air at 200 degrees Celsius.
The heating station has been turned off by the school girl. Xu Qiu put on special heat-insulating gloves and took off the petri dish with the substrate on it.
After waiting for a minute or so, when the temperature of the petri dish drops below 100 degrees Celsius, he directly transfers it to the transfer compartment of the spin-coating glove box.
There is a very thick layer of thermal insulation coating on the thermal insulation gloves, so there is no need to worry about the risk of burns.
In theory, it is necessary to cool the substrate to room temperature and then transfer it, but from the perspective of work efficiency, his method saves time.
Of course, there is a prerequisite for such an operation, that is, the annealing operation of the zinc oxide substrate does not require the subsequent cooling process.
Because the zinc oxide prepolymer material has formed stable zinc oxide nanoparticles under high temperature conditions, the cooling rate has no significant effect on its performance.
Unlike steel annealing, slow cooling is required, because this process will be accompanied by phase changes such as the release of residual stress, the refinement of grains, and the elimination of defects.
Xu Qiu entered the spin-coating glove box and began planning the experiment.
In the current state, he already knows the optimal conditions, and what he has to do is to make the optimal conditions look like what he found out today.
At the same time, repetitive experiments should be taken into consideration to avoid accidents caused by experiments.
After thinking for a while, he decided to divide the 24 substrates into two groups to prepare two batches of devices.
Among them, the strategy of the first group is to screen the experimental conditions in a relatively large range, using 18 tablets;
In the second group, the experimental conditions are directly locked at the optimal conditions, using 6 tablets, and the three systems can each be divided into 2 tablets.
He also thought ahead about how to deal with the experimental accident, such as one or two pieces of film not coated.
In this case, we can only sacrifice the school girl and cut her system by one or two.
No way, his system currently has the highest priority.
It is better to finalize the article as soon as possible after receiving the revision comments.
Just as Teacher Wei said, Chi has changed.
...
Today, Xu Qiu basically turned around, ordered takeaway at noon, settled lunch between the vapor deposition devices, and went to the cafeteria to eat at night, but it only took half an hour before he hurried back to the laboratory to continue the experiment.
Two batches of devices are made in one day, and all the tests are completed, the pressure of the experiment is still relatively large.
Fortunately, the final experiment results are good, and all the hard work is worth it.
Overall, the results of the simulation laboratory last night were repeated.
His PCE11 system has the highest value of 11.11%, which has increased by 0.01%.
This improvement is negligible, but this number is quite interesting, as if to mock him.
In the two systems of school girls, one has a maximum of 6.63% and the other has a maximum of 7.30%.
At present, it seems that in her work, it is not a big problem to publish two articles of ACSAMI level.
Of course, it must be posted as soon as possible.
As the research progresses, the field of organic photovoltaics as a whole is moving forward, so the threshold of efficiency will continue to increase.
Now in the field of organic photovoltaics, a new donor material is developed for the fullerene derivative system. The photoelectric conversion efficiency of 6%, 8%, and 10% are the three thresholds, corresponding to the second zone, the first zone and the top issue respectively .
It may become 7%, 9%, 10% in a few years.
If there is a breakthrough, it is possible to raise the threshold of the second district to 9% or even 10%.
...
At ten o'clock in the evening, Xu Qiu sent Han Jiaying back first, and then returned to the bedroom.
Only Ren Bin is in the bedroom, Tao Yan hasn't returned yet.
He was surprised to find that Ren Bin was uncharacteristically not playing games, but was seriously doing PPT in front of the computer.
Xu Qiu joked, "Binzi, how did you get the hang of it today?"
"Hey, I was forced to be helpless." Ren Bin sighed and said:
"I have chosen too many courses this semester. It is about to expire now. There are several elective courses for final assessments and reports."
Xu Qiu nodded. It is true that some courses are not suitable for written examinations, and the assessment is carried out in the form of reports. When encountering a large number of students, it is necessary to arrange the students' report time about one month in advance.
"Are you going to talk tomorrow?" Xu Qiu asked tentatively according to Ren Bin's character.
Ren Bin smiled and said, "Yeah, so I'm going to make a surprise tonight."
As expected, Xu Qiu glanced at Ren Bin's progress, and now he has only completed three PPTs.
And like this kind of final assessment report, according to Xu Qiu's habit, he would prepare ten to twenty pages.
"Then you are busy, I'm going to take a bath." Xu Qiu said, it's better not to disturb him.
"Well, good." Ren Bin replied casually.
...
After taking a shower, Xu Qiu returned to his writing desk, thinking for a moment, and felt that the article should be settled as soon as possible.
During the day, he used the gap between experiments to complete about 70% of the modification work, and now there is about 30% left.
So he turned on the computer and started working.
It didn't take long for the door lock to turn in the direction of the bedroom door.
Tao Yan came back. He glanced at his two roommates, they were all busy people, one was doing PPT, the other...
"Xu Qiu, what are you doing?" he greeted.
"Change the article." Xu Qiu said.
"Well, I look at ~EbookFREE.me~ Tao Yan casually hung his schoolbag on the stool, and walked towards Xu Qiu. He glanced at the computer screen and said in surprise:
"AdvanceMaterial, AM? Xu Qiu, are you going to post AM?"
Ren Bin is not very sensitive to the academic circle. After hearing the conversation between the other two, he just raised his head and glanced up, then continued to lower his head to do PPT.
Xu Qiu's words, he generally doesn't work with a computer in the dormitory, so his AM article Tao Yan is unaware of it, mainly because he is afraid of Tao Yan talking nonsense.
However, now that we are only one step away from accepting the article, there is no need to cover up.
Thinking of this, he admitted openly:
"Yes, I just received revision comments for the article today. All three comments are positive. I am writing comments and replies and revising the manuscript."
"Xu Qiu, you are silent, and you have made a big news." Tao Yan sighed, then rubbed his fingers and said, "Don't say anything, you know."
"I understand," Xu Qiu said with a smile: "When the article is published, I must treat you."
"It's pretty much the same." Tao Yan said with satisfaction.
"Ah, a treat?" Ren Bin also reacted and hurriedly said, "Don't forget me, too."
"Don't worry, I won't forget you naturally." Xu Qiu said.
Hey, this article hasn't been published yet, and I owe two meals.
The little friends and roommates in the laboratory, let's treat them separately.
Xu Qiu shook his head, sent Tao Yan away, and continued to work.
After earnestly adding an hour to the shift, I finally got all the related matters related to the article revision completely settled.
Considering that tomorrow is Friday, he has class in the morning.
So he sent the revised draft and comment reply letter file directly to Teacher Wei by email.
Get it done, call it a day.
