I Have a Research Support System

Monday group meeting.

First, Wu Feifei and Tian Qing reported.

Originally, the work of the two of them was planned to be merged together.

After hearing their report, Teacher Wei suggested that the two should split their work.

If there is no way to publish a high-quality paper in the first district together, it is better to split it and publish two articles in the second district.

One work sells perovskite photovoltaic devices without high-temperature thermal annealing by adding volatile additives.

The other is to focus on the use of CELIV and TOF to study the charge transport mechanism of perovskite photovoltaic devices.

After that, Duan Yun reported that the equipment was set up for a week, but the equipment was still not set up.

After Teacher Wei heard it, his face became as dark as Bao Gong's instantly, and his voice became much more severe, asking:

How long will it take to finish?

It is very similar to what Chen Wanqing described before, and it looks weird.

However, Duan Yun was as immovable as a mountain, and said slowly:

It's almost ready, give me some more time, and I'm trying to solve the heat dissipation problem now.

After several years of ups and downs in the society, Duan Yun chose to continue to study for a doctorate. His ability to resist pressure is relatively strong.

In fact, although Duan Yun can paddle, it is only to the extent that others 996 work 12 hours a day, and he works 10 hours a day.

The main reason for the delay in progress is that it is very difficult for one person to build a set of precision equipment from scratch.

There is always a situation where a problem is solved, and then a new problem is encountered.

Xu Qiu doesn't know much about the field of thermoelectricity, but he only knows about its working principle.

Thermoelectric materials are materials that convert temperature differences into electrical energy.

The function of the Duanyun instrument is to heat one end of the thermoelectric material, cool down or maintain a normal temperature at the other end, and test its electrical properties at the same time.

Then heat dissipation and heat insulation are required to be very good. There must be a material that isolating heat conduction between the hot end and the cold end to prevent the temperature from passing through, and at the same time ensure temperature stability.

It is simple in principle, but it is not so easy to implement it on specific instruments.

For example, it is necessary to meet the condition of controlling temperature fluctuation within 0.1 Kelvin for a long time.

In fact, Wei Xingsi also knew the difficulty, but he still had to give it some pressure, but it seemed that his method didn't have much effect on Duan Yun.

Relatively speaking, Chen Wanqing is more like him.

If it weren't for Teacher Wei's constant pressure on her, with her experimental ability, it is estimated that there is no work done yet.

During graduate school, the relationship between tutors and students is more like a state of checks and balances:

On the one hand, the tutor should urge the student to work harder to meet the graduation requirements, and at the same time help him to make more achievements;

On the other hand, it can't be pushed too fast. If the students drop out of school in a fit of anger, it will also cause a great blow to the teachers.

If a student drops out, the teacher will not only lose one student name, but will also have a negative impact on his reputation. If there is news, it will be even worse.

As soon as the news of dropping out comes out, it will definitely spread in the school. Other students will definitely not think that it is the problem of the student who dropped out, and will blame the problem on the teacher.

It will be very difficult for this teacher to recruit graduate students in the school in recent years, so he can only try to trick students from outside the school into the pit.

Just like He Xilan in the Materials Department, the reputation of persuading to quit has spread throughout the school, so all her students are from other schools.

But relatively speaking, between teachers and students, students are still relatively weak.

If encountering a BT tutor, the student's countermeasures are very simple, and basically the only way to go is to drop out of school.

Because whether a student can graduate smoothly or not depends almost entirely on the tutor's whether or not to let you go. In this regard, foreign tutors have more power than domestic ones.

Such as revision of graduation thesis, arrangement of defense, including various graduation-related documents, all require the signature of the tutor to take effect.

It was revealed before that some students met the school's graduation requirements, but the tutors have not let them go.

He first used his tutor's account to pass his graduation request online, and then forged his tutor's signature.

Naturally, it was discovered later, but the matter did not become a major issue, the news was only spread within the department, and the student graduated smoothly in the end.

...

Then, Chen Wanqing reported that her ternary conjugated copolymer donor material had an efficiency of 8.24%.

That's right, 8% efficiency, is there room for further improvement? Wei Xingsi asked.

Chen Wanqing was silent for a moment, then shook her head.

Okay, then add other experiments, make a few more batches of devices, and start writing articles. Teacher Wei said:

When writing an article, pay attention to the language expression. Let Xu Qiu help you read it, especially the abstract and conclusion.

OK.

Is there anything else?

there is none left.

When is the next test of the light source scheduled?

After the National Day, I don't remember the exact time.

Okay, don't forget to ask me to do a safety audit of the light source in advance.

After Teacher Wei finished speaking, he took out an envelope from the drawer and handed it over.

Xu Qiu, I received an email this morning, and your article has been accepted.

Xu Qiu stood up, took the envelope, and weighed it.

It is estimated to be about 1,000 yuan. After all, the impact factor of the journal AELM he published is not high, only 5 or 6.

Everyone, congratulations to Xu Qiu. Wei Xingsi took the lead in applauding.

He also took a special look at Duan Yun, which probably meant, You see that others have achieved results, but what about your achievements?

Duan Yun also had a hard time in his heart, and he knew that he might as well have switched to photovoltaics.

Xu Qiu put the envelope in his experiment notebook and began to report the progress of the experiment last week.

The P2FBT4T system now has an efficiency of 6.97%, and there is still room for further improvement.

In addition, he also mentioned that other research groups may also be working on this system.

Teacher Wei was very happy when he heard the first half, but his expression changed immediately after hearing it.

Xu Qiu thought to himself, could it be that Mr. Wei cared so much because he was robbed of his results when he was doing scientific research?

Wei Xingsi stood up, paced in the room while thinking.

Ten seconds later, he stopped and asked:

Has the newly purchased monomer material arrived?

Judging from the logistics information provided by the other party, it is estimated that it will arrive tomorrow.

How much did you buy before, is it enough?

Two hundred milligrams.

Let's add another 200 mg to each, and now I want to compete with others for time.

Xu Qiu, when the monomers arrive, you should immediately go to Zhangjiang to do the synthesis, and submit two reactions for each to prevent accidents such as experimental failures.

After finishing speaking, Wei Xingsi turned to Chen Wanqing again and said:

Wait for the batch of materials that Xu Qiuxin synthesized, and make a batch of devices quickly. If the efficiency of the device can reach 8%, you should stop the work of your subordinates first and help him first.

Chen Wanqing nodded, feeling in her heart:

Unexpectedly, my dignified doctoral student was also reduced to working for undergraduates.

However, Xu Qiu's comprehensive research strength in the field of organic photovoltaics should be close to or even surpass his own.

It's really scary for young people.

Thanks to Blazing Jianmang for rewarding 1,000 starting coins, and turning around and breaking the city for rewarding 100 starting coins.
