I Have a Research Support System

The previous four questions all required Xu Qiu to make corresponding revisions in the article.

In addition, there are some other questions that do not need to modify the text, and can be answered directly in the reply letter.

For example, one reviewer asked, How soluble is this material in common solvents?

Xu Qiu remembered that in the main text, he had related introductions about the solubility properties of materials.

He looked for it, and sure enough, in the material synthesis part of the text, it was written: P2FBT4T-2OD material has excellent solubility in chloroform, chlorobenzene, dichlorobenzene and other solvents.

Such questions are of little value.

The reviewer asked, and it is very likely that he did not pay attention to the details in the article.

But you can't hate others, Xu Qiu first thanked the other party for their opinions, and then quoted the corresponding original text in the article into the reply letter.

...

After dealing with the comments of the reviewers, there is also the most efficient update and the issue of material renaming, which also need to be explained.

Xu Qiu directly wrote these two points at the top of the reply letter, telling the editor:

During the submission of the article, the highest 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 the 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 should also be changed, but he didn't plan to make major changes.

He is going to list the devices to be made today, which is expected to exceed 11% efficiency data, separately.

That is to add a new line in 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 that repeated experiments are not necessary.

After all, according to the requirements of AM, it is difficult to repeat five batches or more than ten batches of devices in a short period of time, unless the simulation laboratory is used.

But Xu Qiu was more cautious. He felt that it would be better to have a clear distinction between simulation and reality, and he didn't want to use the experimental data obtained in the simulation laboratory directly for reality.

Because if you use it once, you will use it a second time.

If you do 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 that you did the experiment in your dream.

As for the change of the material name, it is also quite troublesome. The text part, diagrams and the like must be changed accordingly, and unified into PCE11.

He changed all the parts that could be changed, and highlighted the parts that could not be changed first.

...

After roughly writing the reply, Xu Qiu looked at the time, and it was about ten minutes before the end of the annealing, so he communicated with Chen Wanqing:

Senior sister, how is it? After reading the reviewer's comments, do you feel anything?

This AM is stable. The comments you received are easy to correct, and there is a suggestion in it to be published directly. Chen Wanqing said enviously: Thinking about the articles I submitted, they are all ill-fated.

Really, Xu Qiu touched his head and said with a smile:

By the way, this is the first time I've seen it. The review comments require supplementary descriptions in the experimental operation section.

Hmm... Chen Wanqing thought for a moment, and said, They probably want to do similar research, how do you write the experimental operation part?

I just wrote down the entire experiment process, but I didn't expand on the specific details, such as spraying, heating the substrate, etc., Xu Qiu finished, and added:

I see other people writing that too.

Yeah, that's normal, Chen Wanqing nodded and said:

It's unrealistic to describe the whole experimental process in words. You can write it according to your own ideas and try to be as detailed as possible. If anyone is really interested, they will send us an email to inquire later.

You still send emails to inquire? Has the senior sister ever encountered such a situation? Xu Qiu was surprised.

That's right, I've experienced it before. Chen Wanqing brushed her hair, and began to speak eloquently:

I was doing electrospinning during my master's degree. I saw a document published on JMCA and thought it was very inspiring, so I 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 contents, but I couldn't spin the fibers with a diameter of 200 nanometers they said.

Later, I went to my supervisor, and he told me that ‘for articles published in academic journals, if other researchers have any questions, 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 research institute in China, so I emailed their corresponding author directly.

What happened next? Xu Qiu asked.

Later, I received a reply that day, Chen Wanqing said:

Their corresponding author, that is, 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, who is probably the first author of this article.

In the end, it was the student who replied to me, saying that their addition was 1% mass score.

Did the senior repeat it in the end? Xu Qiu asked.

No. Chen Wanqing spread her hands helplessly.

Ah, why? Xu Qiu asked curiously.

Because of the 1% condition, I tried once before sending the letter, but it didn't work. I tried 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 saying in the academic circles that when it comes to experimental articles, the researchers themselves don't believe what they have done, but everyone who reads it believes it.

As for the theoretical type of articles, researchers usually believe in their theory deeply, but others always feel that this broken theory is full of flaws.

Xu Qiu was speechless.

However, thinking about it carefully, what Senior Sister said seems quite reasonable.

After a while, there was a slight beep beep sound from the direction of the laboratory.

Then, the sound stopped, and he heard Han Jiaying's call:

Brother, it's time for the annealing of zinc oxide, I've already pressed the stopwatch for you.

Here we come, here we come. 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. The silicon wafer has been cut into small pieces and is being cleaned.

Xu Qiu remembered the results of his hard work in the simulation laboratory last night, and said:

Junior girl, I'm going to make a device today. By the way, let's help you with the system and optimize the experimental conditions.

Han Jiaying was stunned for a moment, then smiled sweetly and said, Thank you, brother, do you need my help?

No need, you can concentrate on preparing the 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 with an experiment other than the teaching experiment, and it was usually the other way around.

Thinking of this, Xu Qiu felt that the squeeze on the junior girls seemed a bit ruthless in the past few months.

Let's treat her better in the future... Maybe?

...

The ZnO substrate was annealed in air at 200°C.

The heating stage had been turned off by the junior girl, so Xu Qiu, wearing special heat-insulating gloves, took off the petri dish with the substrate on it.

After waiting for a minute or so, when the temperature of the petri dish dropped below 100 degrees Celsius, he transferred it directly to the transfer chamber of the spin-coating glove box.

There is a very thick layer of heat-insulating coating on the heat-resistant gloves, so you don't need to worry about the risk of burns.

Theoretically, it is necessary to cool the substrate to room temperature before transferring, but from the perspective of work efficiency, his method saves more 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 obvious impact on its performance.

Unlike the annealing of steel, the temperature needs to be lowered slowly, because this process will be accompanied by phase transformation processes 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 to plan the experiment.

The current state is that he already knows the optimal condition, and what he needs to do is to make this optimal condition look like what he found out today.

At the same time, it is necessary to take into account the repetitive experiments to avoid overturning due to experimental accidents.

After thinking for a moment, 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 experimental conditions in a relatively large range, using 18 slices;

In the second group, the experimental conditions were directly locked at the optimal conditions, using 6 slices, and each of the three systems could be divided into 2 slices.

He also thought of ways to deal with experimental accidents in advance, for example, one or two pieces of film were not coated properly.

In this case, the only option is to sacrifice the school girl and make one or two pieces of her system less.

No way, his system currently has the highest priority.

After receiving the revision comments, it is better to finalize the article early.

As Mr. Wei said, late makes changes.

...

Today, Xu Qiu basically kept going. He ordered takeaway at noon, finished his lunch between the vapor deposition devices, and went to the cafeteria to eat in the evening. However, it only took half an hour before he hurried back to the laboratory to continue the experiment.

Two batches of devices are to be made in one day, and all the tests are completed. The pressure of the experiment is still relatively high.

Fortunately, the final results of the experiment were good, and all the hard work was worth it.

Overall, the results from last night's mock lab were repeated.

His PCE11 system has a maximum value of 11.11%, which has increased by 0.01%.

This improvement can be ignored, but this number is quite interesting, as if mocking him.

As for the two systems of Xuemei, one has a maximum of 6.63%, and the other has a maximum of 7.30%.

At present, it seems that it is not a big problem for her to publish two articles of ACSAMI level in the second district.

Of course, it should be sent as soon as possible.

Because with the progress of research, the field of organic photovoltaics is generally 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 is 6%, 8%, and 10%, which are the three thresholds, corresponding to the second zone, the first zone, and the top journal. .

In a few years it may become 7%, 9%, 10%.

If there is a breakthrough, it is also possible to increase the threshold of the second district to 9%, or even 10%.

...

After ten o'clock in the evening, Xu Qiu sent Han Jiaying back first, and then returned to the dormitory.

Only Ren Bin was in the dormitory, and Tao Yan hadn't come back yet.

He was surprised to find that Ren Bin was uncharacteristically not playing games, but seriously doing PPT in front of the computer.

Xu Qiu jokingly said, Binzi, how did you get better today?

Hey, I'm forced to be helpless. Ren Bin sighed and said:

I've taken too many courses this semester, and it's almost the end of the semester. I have a few elective courses for the final assessment, and I have to report.

Xu Qiu nodded. It is true that some courses are not suitable for written examinations, and are assessed in the form of reports. When there are 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? According to Ren Bin's personality, Xu Qiu asked tentatively.

Ren Bin chuckled and said, That's right, so tonight I'm going to make a surprise attack.

As expected, Xu Qiu took a look at Ren Bin's progress, and now he has only completed three PPTs.

According to Xu Qiu's habit, he would prepare ten to twenty pages for a final assessment report like this.

Then get busy, I'm going to take a shower. 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, thought for a moment, and felt that it was better to finish the matter of the article as soon as possible.

During the day, he took advantage of the gaps in the experiment to complete about 70% of the modification work, and now there are about 30% left.

So, he turned on the computer and started working.

Not long after, there was the sound of the door lock turning from the direction of the bedroom door.

Tao Yan came back, he glanced at his two roommates, they are both busy people, one is doing PPT, the other...

Xu Qiu, what are you doing? He greeted.

Changing the article. Xu Qiu said.

That's right, let me take a look. Tao Yan casually hung the schoolbag on the stool, and then walked towards Xu Qiu. He glanced at the computer screen and said in surprise:

Advance Material, AM? Xu Qiu, are you going to send an AM?

Ren Bin is not very sensitive to the academic circle. After hearing the conversation between the other two, he just looked up and continued to do the PPT.

As for Xu Qiu, he usually doesn't use the computer to work in the dormitory, so Tao Yan didn't know about his AM article, mainly because he was afraid that Tao Yan would gossip.

However, now that the article is only close to being accepted, there is no need to hide it anymore.

Thinking of this, he admitted openly:

Yes, I just received the revision comments for the article today, and all three comments are positive, and I am currently writing comments and revising the manuscript.

Xu Qiu, you are so quiet, you have made big news. Tao Yan sighed, then rubbed his fingers, and said: Don't say anything, you understand.

I understand, Xu Qiu said with a smile: When the article is published, we must treat the guests.

That's about 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. Xu Qiu said.

Hey, this article hasn't been published yet, but I owed two meals to go out.

Friends and roommates in the laboratory, please treat them separately.

Xu Qiu shook his head, dismissed Tao Yan, and continued working.

Seriously worked overtime for an hour, and finally finished the related matters of article revision.

Considering that tomorrow is Friday, he has classes in the morning.

So he sent the revised draft and opinion reply letter files directly to Mr. Wei by email.

Done, call it a day.
