I Have a Research Support System

The next day, Xu Qiu got up early.

After eating breakfast and doing morning exercises after eight o'clock, it was boring to stay in the dormitory, so I got up and went to the laboratory.

Walking to the door of Caiyi 216, he was surprised to find that the door was ajar, which meant that there were people inside.

Who is it?

Open the door and have a look.

It was Tian Qing.

It was really unexpected, among the group of five in the laboratory, most of the time Tian Qing was the last one to come.

Because Xu Qiu is an undergraduate student, he has relatively free time, so he arrives at the laboratory early and late.

Others, such as Wu Feifei and Chen Wanqing, usually arrive more than ten minutes earlier, and Duan Yun usually gets stuck.

As for Tian Qing, being late is normal for her.

However, Teacher Wei always turned a blind eye to her.

On the one hand, Tian Qing only plans to study for a master's degree, and the other four are all doctoral students, so the standards for master's and doctoral students are naturally different.

Of course, this is not the main reason.

The main reason is that she will complete the work assigned to her by Teacher Wei seriously, and her work efficiency is also high.

Moreover, her recent work has also made great progress and is being compiled into an article.

In addition, her grade point is very high, and her English score is naturally not bad. The speed of writing papers is not slow, and the quality is not low.

Before, Xu Qiu heard Teacher Wei mention that it would be great if Tian Qing could stay and study for a Ph.D.

It's a pity that everyone has their own aspirations and should not be forced.

...

Tian Qing sat at the desk with a PAD on the desk.

She herself is holding a tablet in one hand and a paintbrush in the other, as if she is drawing.

Good morning, Senior Sister Tian Qing. Xu Qiu took the initiative to greet her.

Morning, come and see how my painting is doing. She waved to Xu Qiu.

Xu Qiu walked over to take a look. The cartoon style of big head and small body, isn't this Teacher Wei, the drawing is quite vivid.

This is Teacher Wei. Xu Qiu said.

That's right, my previous digital tablet was broken, and the new one just arrived by courier today, so I tried to use it, and it feels pretty good. Tian Qing said.

Xu Qiu felt relieved, no wonder she came so early, she was here to pick up the courier.

Room 201 on the first floor of the material is the residence of the doorman, who can also help to collect express delivery.

Xu Qiu, I'm going to draw a cartoon picture for every little friend in the lab, Tian Qing said:

Since you came first, let's start painting from you.

Yes, how can I cooperate? Xu Qiu naturally had no reason to refuse.

Well, you just face me, just don't move around, Tian Qing said:

Of course, if you want something like a back view, or have other special requirements, you can also ask for it.

Let's be normal. Xu Qiu said.

The desk in the laboratory is a large square table where everyone sits together.

He found a seat facing Tian Qing and sat down.

Xu Qiu, take it easy.

good.

Why does it feel like a guinea pig.

Tian Qing draws very carefully, while observing Xu Qiu, she writes.

Because it is a simple cartoon, it only took a few minutes to complete.

How is it? Tian Qing asked.

It's quite vivid. Xu Qiu praised after checking it.

It has to be said that Tian Qing's drawing talent is still good, and the illustrations of her undergraduate graduation design were hand-painted by herself.

Besides painting, she has many other hobbies, such as playing the ukulele.

After ten o'clock in the evening, after get off work, when she occasionally got in the mood, she would take it out and play it.

The reason for choosing this time period is that the sound insulation of the corridor is not good, and playing at this time will not disturb the people.

At around 9:20, others arrived one after another.

Chen Wanqing, Wu Feifei and Duan Yun each like to mention a cartoon picture.

However, Han Jiaying did not show up throughout the morning.

The tool man who had just been cultivated and matured just disappeared.

Maybe there is something wrong.

Xu Qiu shook his head and buried himself in writing the article.

...

Around two o'clock in the afternoon.

Han Jiaying walked into the laboratory in casual clothes and carrying a schoolbag.

Why didn't you come this morning? Xu Qiu asked casually.

Oh, I went to the boiling point club's event last night. The rehearsal was very late, so I didn't get up this morning. Han Jiaying said:

By the way, there will be a school-level performance in two weeks' time. It's a student organization's welcome party. Would you like to come and watch it? I can get a few tickets.

Xu Qiu was waiting for a reply when Duan Yun beside him said excitedly:

The party? When does it start?

It should start at six o'clock, and the end time will be around nine o'clock. Han Jiaying said.

That's good. We can go there after dinner, watch for a while, and then rush back to the laboratory before 7:30. Duan Yun said.

Duan Yun meant that he agreed, and Han Jiaying turned to look at Xu Qiu and Chen Wanqing.

I'm fine. Chen Wanqing said.

I'm fine. I heard that you will perform on stage? Xu Qiu said.

Yeah, but I haven't got the program list yet, I'll talk to the person in charge later, and try to put my program at the top.

What kind of show are you, single person or multiplayer? Xu Qiu asked.

Secret, I'll find out when the time comes. Han Jiaying chuckled:

I'll go to the lab and inform Wu Feifei and Tian Qing.

Okay, you can go. Xu Qiu said.

Not long after, Han Jiaying came back with a smile on her face and said:

They also agreed.

Xu Qiu nodded and said:

How is the experiment going? You should also make devices for your three systems this week.

After hearing the device, Han Jiaying's face immediately fell, and she said aggrievedly:

The devices of several systems I made for senior sister Chen Wanqing have good efficiencies, but the highest efficiency of the devices for my own three systems is only 4%.

4%, it's not too low. When I was doing PBT4T before, I started with 4%, and then slowly reached 10%. Xu Qiu first encouraged the juniors.

In fact, the three systems for the school girls use BT units with two fluorine atoms, and the side chains are the same OD side chains as his, which is equivalent to preliminary optimization.

The only difference between their molecular structure and Xu Qiu's system is the number of thiophene units, his is 4, and the junior's are 2, 3, and 5 respectively.

Therefore, the names of these three materials are respectively P2FBT2T-2OD, P2FBT3T-2OD, and P2FBT5T-2OD, which can be abbreviated as P2T, P3T, and P5T.

The system that has been preliminarily optimized has a maximum efficiency of only 4%. If the school girl did not make a major mistake in the experimental operation, it shows that the upper limit of these three materials may not reach 10%.

Even so, the cake that should be painted still needs to be painted, and if there is a miracle, that's not sure.

Xu Qiu continued to analyze:

The performance of your current device is not high, there may be two reasons:

The first is that there is a problem with your experimental operation, or the choice of experimental conditions is wrong. If you can find and correct it in time, the efficiency may be greatly improved.

The other is the reason of the material itself. The upper limit is relatively low, so this problem is more difficult. At this stage, we don’t actually have a good solution.
