I Have a Research Support System

At the end of the conference, Gong Yuanjiang got up and said: "This seminar on the development of organic solar cells has come to a successful conclusion. Thank you to all the visiting teachers and students. We will entertain you on the fourth floor of the cafeteria of Kainan University at six o'clock in the evening..."

The participants left the venue in an orderly manner, Wei Xingsi took two steps to the side, came to Xu Qiu, and said, "Xu Qiu, please summarize what you have gained from this meeting, and share it with everyone at the group meeting tomorrow, and help me by the way." Inform Wu Feifei that they will hold a group meeting tomorrow afternoon."

"Okay." Xu Qiu nodded in agreement, and then casually sent a message in the group chat of the research group: "A group meeting will be held tomorrow afternoon", and soon received a row of emoticons, such as covering face, shocked and so on.

Wei Xingsi looked at Mo Wenlin next to him again, and said, "Mo Wenlin, have you bought your high-speed rail ticket tomorrow, and come back with us?"

"Well, I've bought it," Mo Wenlin responded, "The train is G5, and it's the same train as you and the teacher, but the seats are not together."

"It's okay," Wei Xingsi waved his hand, "I'll take a step first, see you later at dinner." After speaking, he left with his briefcase under his arm.

"Lend me the experiment notebook?" Xu Qiu shook Mo Wenlin's notebook in his hand.

"Send it to you," Mo Wenlin said nonchalantly, "It's a new one anyway."

"Okay," Xu Qiu was not polite, took a roll of the notebook, held it in his hand, waved his hand, and said, "See you later."

"Goodbye." Mo Wenlin smiled.

Back at the hotel, Xu Qiu checked the time. It was 5:20, which was still early for dinner, so he went to take a shower.

After a few minutes of resolution, Xu Qiu sat at the table wrapped in a bath towel and turned on the computer. He planned to type the words recorded today into the computer.

Memories are time-limited. He is afraid that the time will be too long, and he will not be able to recognize what he has written. Before, he thought that he had the potential to be a doctor, but that was all an illusion...

Xu Qiu opened the experiment notebook, and a smell mixed with paper, ink and Mo Wenlin's eau de toilette came out.

As for the specific fragrance, Xu Qiu couldn't tell, gardenia, lily of the valley, rose, lavender, or something else?

He only knew that this type of fragrance was either extracted from natural plants or synthesized in an organic synthesis laboratory.

The structures are usually alcohols and ketones, with some unsaturated double bonds and other structures, which can combine with olfactory cells to generate electrical signals, which are transmitted to the brain to form a sense of smell.

In fact, the structure of most cosmetics is very simple. You can buy a ton for a few hundred dollars, but with a little packaging, you can sell dozens or even hundreds of dollars for 100 grams.

For example, Vaseline (translated from vaseline in English) is a long-chain alkane mixture, usually a wax ointment extracted from the residue left after distillation of crude oil at atmospheric pressure and reduced pressure. It is also the main component of some lipsticks in the world. Ingredients, and a paste the size of a finger knuckle can sell for a few dozen soft sister coins.

Because, most of the time, customers buy a brand, and most of the money they spend is spent on brand marketing or advertising.

Of course, part of it will be used for research and development of new products.

Cosmetics companies also have research and development departments, which are somewhat similar to scientific research institutions, which constantly iterate molecular structures, processing techniques, formulas, and so on.

The essential difference between research and development and scientific research is that the former is for industries that have already been applied, in other words, there is money to be made, while the latter is not applied for the time being and may not be applicable in the future. It cannot make money at the moment.

Xu Qiu entered all the contents of the experiment notebook into the computer. It was already 5:50 at this time. Before he had time to make further arrangements, he hurried to the fourth floor of the cafeteria.

It wasn't hard to find the big team. Xu Qiu saw a person with a big bald head from a distance, reflecting the light brightly. He had seen this person in the venue before.

Following the bald head's guidance, Xu Qiu found Wei Xingsi, but Teacher Wei's table was already full of people, and they were all teachers, not students.

Xu Qiu didn't go to join in the fun, and took another two steps. When she saw Mo Wenlin, she specially reserved a seat for Xu Qiu. Xu Qiu greeted her and sat down next to her.

In the past few days, Mo Wenlin was dressed more delicately, and she also wore an unknown perfume, which might be a famous brand. Xu Qiu knew nothing about it, so she couldn't smell it.

For example, the original girls in the group, including seniors and juniors, are usually plain-faced, and I don’t know why Mo Wenlin chose to major in chemistry and put in so much effort to put on good makeup. All makeup removed.

However, Mo Wenlin just came to Gong Yuanjiang's research group, so she didn't have the opportunity to enter the laboratory in the near future.

Speaking of which, Han Jiaying would also put on make-up and dress up on a Saturday date. It is said that girls will show their best side in front of the person they like.

Could it be?

Uh... I can't think deeply about this topic.

After sitting down, Xu Qiu looked around for a while, and felt that the standard of dinner this time was not as high as that on Friday, probably because there were more people eating this time, and the standard dropped when it was average. .

Like Wei Xingsi and the others are special guests, they came two days in advance and were entertained by the host, while most of the other people who came to listen came back and forth on Sundays, or came on Saturdays, and stayed for one night at their own expense. Now these people also came here It's time to eat.

There is no teacher at the table, they are all students, so no one persuades them to drink, so they eat, drink, and chat normally.

On the whole table, Xu Qiu didn't know many people. Except for Mo Wenlin next to him, there was only Cao Si, the big brother in Gong Yuanjiang's group, and Lu Binghui.

Xu Qiu found that Lu Binghui looked at him and Mo Wenlin with complicated expressions. It might be that Gong Yuanjiang mentioned something to their students. Lu Binghui, I can only say that brothers and we are destined for each other.

Cao Si has been enlivening the atmosphere, sometimes organizing everyone to have a toast or something.

Because I didn't drink much, dinner didn't take long, and it ended quickly.

The teachers at the next table didn’t drink much today. Xu Qiu reckoned that some of them were relatively close, in Jincheng or in the next city. After dinner, they probably had to catch the high-speed train back, maybe they could catch up CCTV set at 8 o'clock, watch a drama with my wife or something.

Xu Qiu and Wei Xingsi's schools are far away in Shanghai, so they can only stay one extra night.

After dinner, the teachers still had activities, and the students disbanded on the spot.

Xu Qiu went straight back to the hotel, first made a phone call with the junior girls and chatted, and learned about their test results.

Xuemei is based on the PBDB-T:ITIC system, and the photoelectric conversion efficiency can reach up to 9.2%. The initial test results show that the matching between the two is very good; Wu Shengnan repeated Xu Qiu's system, but the efficiency is slightly lower. It may be due to unskilled experimental operation; Chen Wanqing went to Zhangjiang to continue the unfinished IEICO and IEICS synthesis experiments.

After hanging up the phone, Xu Qiu entered the simulation laboratory and checked the Gong Yuanjiang laboratory copied from yesterday morning.

The medicines in their laboratory are basically useless to Xu Qiu.

On the one hand, even if the drug is copied, others usually will not draw the specific molecular structure of the material on the reagent bottle, and usually use the name code, and the meaning of many code names is known only to the experimenter himself, such as H22, Before this structure was published, other people would not be able to guess what it was. They didn't know the specific molecular structure, and it was useless to get the test data.

As for deducing the structure with materials, it is very difficult to deduce the structure of unfamiliar and simple small molecule materials, not to mention the complex polymer materials in the field of organic photovoltaics. It is almost impossible to deduce the molecular structure through materials. things.

On the other hand, and also the most important reason, Xu Qiu disdained to do things like stealing the fruits of other people's labor.

Copying Gong Yuanjiang's laboratory, Xu Qiu mainly took a fancy to the multiple glove boxes lined up in their group. Using this as a device may have better performance.

Gong Yuanjiang and the others can operate in the glove box throughout the whole process, unlike the two glove boxes in Mr. Wei’s group, which are independent. After the effective layer film is spin-coated, it needs to be transferred in the air, and they focus on organic photovoltaics. Cross-contamination with perovskite devices is avoided.

What Xu Qiu wanted to understand was how much the difference in the glove boxes in the two laboratories would affect the final result.

If the impact is relatively large, we have to find a way to get Mr. Wei to get more glove boxes out.

But objectively, there is a very difficult problem, that is, the area of ​​the Handan laboratory is too small, even if the instruments are in place, there is no place to put them, and there is no spare room in the department.

However, Xu Qiu often heard rumors from the school during his undergraduate years. The old principal has always wanted to let the school's science and engineering departments, including the eight major laboratories of materials, chemistry, physics, biology, and environment, jointly All the postgraduate students moved to the headquarters outside the Handan campus, making the headquarters only a teaching place for undergraduates.

At present, Shanghai Magic City University has four major campuses. The Zhangjiang campus is mainly for the School of Pharmacy, the School of Computer Science, and the School of Software. The Fenglin Campus is mainly for medical students, Linba and Linwu. The Jiangwan Campus is mainly for law students. , Handan campus is the largest, and students of other majors are currently here.

If the laboratory can be moved to other campuses, such as Zhangjiang, then the problem of insufficient laboratory space may be solved.

However, this kind of thing that involves multiple departments, especially the relocation of science and engineering laboratories, will be very, very difficult.

For example, the glove box with the evaporation chamber in Mr. Wei's laboratory weighs several tons and is difficult to move, and similar equipment is available in almost every laboratory.

For another example, precision instruments such as electron microscopes may have a lifespan of ten years. If you move, you will directly subtract more than two years from the lifespan. Some old equipment may directly lose watts when you move there.

In addition, during the relocation of the laboratory, it is definitely impossible to do experiments, and it also involves re-adjustment of equipment. There may be a transitional window of half a year or one year. What if the relevant graduate students cannot complete the experiment? Can the completion be postponed?

Some experiments have to run continuously for several months or even a year or two without stopping, so what should we do, stop them forcibly, or postpone the relocation?

These are all questions.

Because of this, Xu Qiu had been in college for four years, and he had shouted the slogan of moving for four years, but there was still no movement.

However, it is said that the current old principal is about to change his position, and it seems that he has plans to implement this matter before leaving, and the recent slogan has become louder again.
