I Have a Research Support System

After knowing the basic situation of the two new members, Xu Qiu took them to visit the laboratory.

Because the laboratory is only blocked by a glass wall, the sound insulation effect is almost zero, so Chen Wanqing and Wu Feifei also heard Teacher Wei's introduction just now.

Everyone welcomes new members.

Now, the organic photovoltaic team has expanded to three people, and the perovskite photovoltaic team has also been expanded to three people. Although Tian Qing is doing mechanism research, she is now mainly working on perovskite.

Only Duan Yun, who is still struggling, is working in the thermoelectric field.

"Whether it is an organic or perovskite photovoltaic device, the battery structure is similar, which is a sandwich structure similar to a sandwich.

From bottom to top are substrate, electrode, transmission layer, active layer, transmission layer, electrode.

Among them, the main experimental operations involved include substrate cleaning, spin coating, vacuum coating, device testing and so on. "

"This is the glove box, which is also the place where the effective layer is prepared, and there is a nitrogen atmosphere inside..."

Xu Qiu introduced it eloquently.

Once upon a time, he also changed from the person he was taught to a mentor on the road of scientific research.

"Today I will teach you how to clean the substrate."

Han Jiaying and Chen Mingbo also started their lab chores.

...

At around 5:30 in the afternoon, after Xu Qiu made an appointment with them to come to the laboratory, the two left.

After all, they are still junior students, and there are still many academic courses.

Moreover, Chen Mingbo also studied a second major in economics, so he has even less free time.

This second specialization does not have much practical use, it is purely out of interest.

And the barrier to entry is low.

Generally, you start to apply during the summer vacation after the freshman year. As long as you apply, you can basically pass it.

The second college is two academic years, that is, sophomore and junior, or junior and senior, and needs to take about 36 additional credits, and a tuition fee of 130 yuan is required for each credit.

In addition to the second college, there are also two degrees, such as the second degree in philosophy, which requires a sophomore to a senior year. After completing the three academic years, the courses add up to a total of about 50 credits, and additional tuition fees are also required.

The courses taken are all professional courses, and some courses even have to take classes with students of the same major and take exams together.

Moreover, there are also grade requirements. For example, if the grade point is higher than 2.0, the corresponding second college and second degree certificates will be issued if there is no failure.

...

In the evening, Chen Wanqing transferred the devices prepared today to the vacuum coating machine and started vacuuming.

After finishing, she returned to the desk and sat down, but before the stool was warmed up, Wei Xingsi came to 216 and said to her:

"There is good news, just received the email, the editor agreed to our appeal request, and now we are going to transfer your article to the fourth reviewer for review.

By the way, I read the literature I gave you before, come and tell me about it, Xu Qiu, you can come too. "

Chen Wanqing nodded. She didn't expect the editor to give her another chance, which was a surprise.

Sure enough, we still have to try our best to fight for what should be fought for, and maybe a miracle will happen.

After Teacher Wei left, she rummaged through the literature on the desk and said:

"Wu Feifei, take a look at the evaporation machine for me later."

"good."

"What did Teacher Wei ask me to do?" Xu Qiu asked curiously.

"It's probably to let you understand the general process of the literature, and then let you help me share some literature."

Chen Wanqing sorted out the literature, and there are more than a dozen articles.

She took the document in her hand, brought the experiment notebook and pen, got up and said:

"Let's go, you'll know when you go."

...

The two came to room 218.

Chen Wanqing found a stool and sat down with ease, and Xu Qiu also sat next to her.

"Let's get started." Wei Xingsi said while operating the computer.

"In this article, they synthesized a series of polymer donor materials to optimize the photoelectric performance of the device by regulating the side chain," Chen Wanqing said:

"It turns out that those with thiophene side chains perform best."

"Why is it better to have a thiophene side chain? Have you ever thought about this problem?" Teacher Wei asked casually.

Chen Wanqing was stunned for a moment, and thought: "Yes, why?"

She quickly glanced at the abstract of the thesis, but she didn't seem to mention it, so she continued to read...

At this time, a finger stretched out from the side, pointing to a text in the preface.

"Sister, here." Xu Qiu lowered his voice.

"Oh, the thiophene side chain can form a conjugated structure with the main chain, so that charges can be transported on a two-dimensional scale."

After Chen Wanqing finished speaking, seeing that Teacher Wei was silent, she added another sentence:

"It's explained in the article."

"Well, go ahead."

After that, Teacher Wei didn't ask any more questions, and whenever Chen Wanqing finished speaking, he responded softly.

It seems that at first he just wanted to give senior sister a bad start.

Moreover, Mr. Wei was also busy with his own affairs. The printer behind him was working from time to time, making a humming sound.

...

"I'm done."

"Finished? Then go and put away the documents." Wei Xingsi said:

"Xu Qiu, you have learned how to speak literature, and you can try to speak later, it will be very helpful to improve your speech ability."

After speaking, he pointed to the printer and said:

"Here is the latest batch of documents. You can staple them up with a stapler. You and Chen Wan will separate the documents on organic photovoltaics. Next time, come and tell me a few articles."

"good."

Xu Qiu picked up the paper from the printer and fixed the upper left corner with a stapler.

Each document is printed on both sides, roughly three to five pages of A4 paper.

There are a total of more than a dozen articles, including organic photovoltaics, perovskite, and thermoelectricity, and the journals are all owned by Wiely.

Teacher Wei should visit the websites of major journals regularly, scan through the newly published literature, find literature related to the three fields, download and print them out.

Picking up the bound documents, Xu Qiu prepared to leave.

At this time, he saw the senior standing next to a file cabinet, sorting out the documents just mentioned and putting them into it.

The paper documents went through a cycle and returned to Mr. Wei's office:

First, print it out from Mr. Wei's office, give it to the students, and after explaining it, put it in his filing cabinet.

This is also Teacher Wei's habit of using paper documents. For example, Xu Qiu and Chen Wanqing usually read electronic documents, which are more convenient for retrieval.

...

The next morning, Chen Wanqing received a notification from the drug warehouse that the previously purchased monomers had arrived in Zhangjiang.

Xu Qiu and Chen Wanqing divided the work, he was responsible for the synthesis, and she stayed in Handan to do some basic characterization.

As for how to allocate the new school girl, it depends on her own choice.

Theoretically speaking, it is more appropriate to start with cleaning the substrate, spin-coating the transfer layer, evaporation, testing, etc. that do not require much technology.

Thank you Hu Zhouda and Lan Shiyu for rewarding 1,000 starting coins. This damn novel wasted my youth for rewarding 100 starting coins.
