I Have a Research Support System

I can give you 82 points for your operation, and give you 666 points for the remaining 18 points. Chen Wanqing said.

She looked at the quotation and found that this page was basically a monomer of the thiophene family.

The difference lies in the number of thiophenes and the kind and position of the branches.

Is he planning to go big and complete?

While Chen Wanqing was thinking, she planned to contact the QQ of the manufacturer's sales, but Xu Qiu snatched the mouse away.

Wait a minute, there is still this page, this and this come in 1 gram, Xu Qiu said:

Except for these three, all other monomers here come with 200 mg each.

Uh...is there any more? Chen Wanqing said helplessly.

Gone.

Okay, I'll try to ask you a question.

Chen Wanqing sent a message to the salesperson to inquire, but did not receive a reply immediately.

Seeing this, Xu Qiu didn't wait.

He headed to the lab to test the stability of the device, which was done twice a day.

After more than twenty minutes, the test was over.

Sister, is there any news? Xu Qiu asked.

Well... At first, they were reluctant, but after seeing that we bought a lot, they reluctantly agreed. Chen Wanqing said:

My system bought a total of three monomers, a total of three grams, and your system bought a total of nearly twenty monomers.

However, we spent about the same amount of money, about 5,000 yuan, with a total budget of 9,800 yuan.

When I designed the molecule, I chose a unit with a relatively simple structure, and it's normal to be cheaper. Xu Qiu said:

In other words, the molecular structure of these monomers is not complicated, can we also synthesize them ourselves?

But I see that more than 80% of the literature does not have steps to synthesize monomers, but only gives a polymerization equation.

If you synthesize it yourself, you can do it, but the synthesis cycle is too long, and reactions such as adding fluorine atoms to the monomer and adding trimethyltin are relatively dangerous.

Therefore, most small research groups buy ready-made monomers from optoelectronic material companies, and then do polymerization.

There are only a small number of large research groups specializing in organic photovoltaics. They have a large number of people and can arrange division of labor and cooperation. Several people specialize in synthesis, a few people do devices, and a few people do optimization. Chen Wanqing said.

Understood, it's like an assembly line. Xu Qiu said.

Basically, for a large research group, most of the graduate students don't actually have too many scientific research ideas of their own, Chen Wanqing said:

They are only trained as 'technical workers' who can perform experiments proficiently and help their mentors realize their ideas.

However, for a small research group like ours, with only one worker, it is impossible to build an assembly line.

Before, I was the only one who silently resisted everything.

But now...

It's even harder for you now, and you have to resist me one more time. Xu Qiu interrupted.

Chen Wanqing: ...

...

In the next few days, Xu Qiu and Chen Wanqing wrote and revised the article together, and he also added two small experiments.

Xu Qiu has plans to synthesize monomers from scratch in the future, after all, there are too many restrictions on buying other people's things.

However, considering the toxicity of the drug and the danger of the experiment, he asked the system:

System, will the use of toxic reagents in the simulated laboratory cause poisoning, or an explosion, will this effect be transmitted to the real world?

[No, the host enters the simulation laboratory in the form of a projection, which has nothing to do with the real host. 】

That's good, it seems that if there is any idea of ​​death in the future, you can also test the water in the simulation laboratory first.

...

Friday afternoon.

The work on the perovskite transport layer is basically completed.

As for the first author of the thesis, the two decided to work together after discussion. Chen Wanqing ranked first, and Xu Qiu ranked second.

From the article level, a total of one shows that the contribution of the two people to this work is equal.

But at the school level, there are a total of the first authors, and in most cases they are considered the first authors.

The marks represented by the paper will be shared equally between the two only at the time of scholarship evaluation.

However, Xu Qiu didn't care too much about the gains and losses. After all, he picked up a lot of skills from his senior sister, and he should return some of them.

...

Saturday.

After working for five consecutive days, it was a rare day off. After Xu Qiu and Tao Yan had lunch together, they returned to the dormitory, lay on the bed, opened the starting point, and read the novel.

After a while, there was a sound at the door. It turned out to be Ren Bin, who was still holding a suitcase in his hand.

Binzi, you're back. Tao Yan said.

Tao Yan, Xu Qiu, you are all here. Ren Bin said.

The two of us returned to school half a month ago, but you failed to fail last semester. Tao Yan said.

Isn't this pre-examination raid effective? I also want to thank you and Xu Qiu, Ren Bin said with a chuckle:

By the way, how do you know that I didn't fail?

The make-up exam started last week. If you didn't come, it means you didn't fail the course. Before every semester, you were counted as early as returning to school, Tao Yan said:

Binzi, are you just saying thanks?

Nothing practical?

Anyway, I also gave you hundreds of megabytes of review materials.

Of course there is. Ren Bin clapped his hands, opened the suitcase, and while taking things out, introduced:

Raisins, almonds, and specialties of our Xinjiang province, cut cakes for a catty.

Brother is not bad, I didn't hurt you for nothing. Tao Yan put down the game console in his hand, jumped off the bed, and said to Xu Qiu:

Xu Qiu, come down to share some snacks.

Xu Qiu had just finished eating, he wasn't very interested in food, and he didn't want to move when he was lying on the bed, so he said:

You can figure it out for yourself, just leave some for me.

After distributing the snacks, Ren Bin said, Are you going to register this Sunday?

Yes, school starts on September 1st, so registration will be on August 31st tomorrow. The location is still the same as usual, in the department office in the east main building of the Twin Towers. Tao Yan said.

The start of school at Modu Comprehensive University starts on the first Monday of March and September every year, and registration is on the Sunday of the previous day.

This year, it happened that September 1st was a Monday. In previous years, school would not start until September 6th.

…………

On Sunday morning, Xu Qiu went to the department office to register.

While waiting for the elevator on the way, I ran into a few acquaintances and classmates.

The registration process is very simple, you only need to swipe the campus card, and then stamp your student ID card.

However, you must be present in person. If you cannot arrive, you need to ask for leave in advance with the counselor.

If you need to buy a student ticket, it will be a little more troublesome. You need to leave your student ID card, and the department will go to the magnetization.

You can buy student tickets four times a year, and if you have not used them up, you can keep the number of times.

If it is used up, it must be magnetized before you can continue to buy student tickets.

Thanks to Shan Weiyong for the 400 point reward.
