I Have a Research Support System

In supplementary experiments, SEM and GIWAXS are relatively troublesome.

The former is a scanning electron microscope, which is used to characterize the film thickness of the effective layer of the device under optimal performance.

On the one hand, it cannot be tested directly in the laboratory, and needs to be tested in the department.

On the other hand, the devices of these four systems are still in the process of performance optimization, and this experiment cannot be carried out.

Otherwise, it is assumed that the current optimal conditions are the mass ratio of receptors is 1:1, the total concentration is 16 mg/ml, chlorobenzene solvent, 110 degrees Celsius, true thermal annealing, 3000r.p.m., no other post-processing means....

The film thickness was measured to be 105 nm.

After waiting a few days, the experimental conditions were optimized again, and the device performance improved again.

There is a high probability that the film thickness will change, so it is necessary to re-test under the new conditions.

GIWAXS needs to go to Modu Light Source to test.

There is one last test opportunity this year, which is scheduled for next Saturday.

This test is an evening file, that is, from nine o'clock in the evening to nine o'clock in the morning of the next day, and it will last overnight.

...

Han Jiaying has an event for the Boiling Point Club this week, a rehearsal on Tuesday, and an official performance on Wednesday, so she asked for two days off.

On Tuesday afternoon, she sent five tickets to the lab friends, and then left in a hurry.

Compared with the previous main members of the laboratory, it is equivalent to only adding one new student.

As for Cheng Mingbo, I saw him twice a week at the beginning, once a week later, and only once every two weeks now.

Because he is not under Xu Qiu's management, Xu Qiu is not clear about his current situation.

Is it simply because of heavy schoolwork that you can't spare time;

Or for other reasons, choose to run away;

Or find another research group and step on N boats.

No matter what the reason was, apart from Wu Feifei occasionally casting envious glances at Xu Qiu, the existence of Cheng Mingbo had little effect on others.

Standing on N boats also reminded Xu Qiu of a classmate of his, Fang Xiaotong, to be precise, was the number one student in his grades.

The relationship between Xu Qiu and her is roughly between nodding acquaintances and acquaintances. It belongs to the kind of academic masters who occasionally meet, but not many personal friends.

Fang Xiaotong has joined the research group since his sophomore year, and has changed four research groups about every semester.

She has been to several large groups in the Materials Department.

In the end, she chose to join the research group of an academician of the Department of Chemistry, and she also joined the Department of Chemistry as a cross-professional graduate student.

Probably because she felt that the temple of the material department was too small to display her talents.

After all, there are no academicians in the Department of Materials Science and Engineering.

The Equipment Academy and Jiangwan Xiancai each have an academician.

However, those units are listed separately. Although they recruit students together with the Department of Materials, they are not under the control of the Department of Materials in terms of management and have their own factions.

I have to say that there are still two brushes that can be listed separately.

For example, Zhan Yuntao, the boss of the Equipment Institute, has a very high level of scientific research, and has countless proud students. His research direction is bacterial engineering equipment, and there is no shortage of project funds.

In addition, policy benefits will also be tilted towards their research group.

For example, a national award quota is allocated separately every year.

For another example, in other laboratories, students and teachers manage experimental instruments and handle trivial matters such as reimbursement.

Zhan Yuntao's research group hired two administrative personnel separately, one is responsible for the registration and management of instruments in the laboratory, laboratory cleaning, etc., and the other is responsible for project fund management, financial reimbursement and other matters.

Of course, these administrative staff are not staffed, and their income is average, but they are still relatively idle.

These things, after Xu Qiu joined the research group, he only learned about it when he chatted with his brothers and sisters.

And before entering this line of work, these things are very difficult to find out.

Regarding scientific research, laymen see many things as the tip of the iceberg. Only when you really enter the field will you discover how big the world is under the iceberg.

Speaking of which, besides Fang Xiaotong this year, the student with the highest GPA also chose to stay in school for postgraduate study.

As for the electrical major, Xu Qiu is not very familiar with it, so he doesn't know the specific situation.

The person with the highest grade point chose to go to Yuan Shu's research group of Jiang Wan Xiancai.

Yuan Shu is mainly engaged in electron microscopy. Although he is not an academician, he is also a leader in the industry. He has focused on the field of electron microscopy for more than 20 years and is proficient in various electron microscopes. There are several tens of millions of electron microscopes in the laboratory.

...

When the school girl was away, Xu Qiu had no choice but to do experiments by himself.

He planned a little bit and decided to carry out the three characterizations of UV-vis, PL, and CV first.

Although there are three tests, there is no need to prepare the device, just spin coating to prepare the thin film, which will not consume too much time.

With the addition of graphics and simple data analysis, it should be done in two days.

At that time, the school girl will come back, and she can help with experiments in the name of helping her deepen and strengthen her experimental ability.

When Xu Qiu got up and was about to go to the laboratory, Chen Wanqing stopped him:

Student, you want to measure the spectrum, right? Measure two samples for me, okay?

What sample? Xu Qiu asked.

As for my three systems, because the donor-to-receptor ratio was changed later, the earlier test can no longer be used, and the spectrum needs to be measured again. Chen Wanqing said.

These are obviously three samples that are easy to cut, Xu Qiu secretly complained.

Of course, if you help, you will definitely help, after all, you are a senior, and you are using a begging tone.

Okay, where's the solution?

In the glove box, I put all three sets of solutions in glass bottle holders, with dates marked on them, and the December batch is that.

What about the spin coating conditions?

Spray coating, 2500r.p.m., thermal annealing at 120 degrees Celsius for 10 minutes.

Okay, I made a note.

After communicating with her senior, Xu Qiu suddenly discovered that the relationship between them, to be precise, the relationship she thought they had, had changed over time.

When he first joined the research group, the senior sister was his first mentor.

As a mentor, she arranged experimental tasks for him, and both parties would feel that it was reasonable.

But in the end, his scientific research ability improved rapidly, even surpassing his senior sister. In her heart, the relationship between the two had changed and became equal.

Even though Xu Qiu still considers her as a mentor in his heart and thinks that this relationship has not changed, Chen Wanqing doesn't think that way anymore.

For example, now, when helping her with an experiment, she has to speak in a softer tone.

Actually, there is no need for this.

This is also his philosophy, the master-student relationship is mainly maintained by emotion.

If you rely on interests to maintain, you must either keep ahead, or you have to keep a hand in the key points.

Not everyone can do the former, and the latter will definitely be scolded by apprentices behind their backs.

Xu Qiu believes that if he treats people sincerely, at least he will not face the worst result.

Just like him and Han Jiaying, although he said investment and experimental tool man.

But when thinking about problems, he would still stand at the perspective of improving the experimental ability of the school girl, rather than just thinking about himself.
