I Have a Research Support System

After confirming the results of the simulation laboratory, Xu Qiu went to the supplies department to get a bag of balloons and a bag of rubber bands, and then took the school bus to the bend of the river.

Because the people from the gas pipeline company are going to go there this morning, and they require that the person in charge must be present during the installation to conduct on-site acceptance.

At the same time, Xu Qiu also made an appointment with Lao Wang in the fume hood in the afternoon, so that two things could be solved at once.

The main reason is that it is very annoying to procrastinate on the decoration. If it is not done well, you will have to run to the bend of the river every three days. Xu Qiu wants to get rid of this matter as soon as possible.

After getting off the school bus, Xu Qiu arrived at Jiangwan Xiancai more than 20 minutes earlier than the agreed time, entered the 522 device characterization laboratory, and turned on the central air conditioner in the laboratory.

At this time, the nitrogen cabinet of Laboratory 522 was already in place, and Xu Qiu had pasted a circle of black and yellow tape on the ground next to the cabinet to be eye-catching and a warning, and there was a bottle of high-purity nitrogen gas filled inside.

Nitrogen is purchased in schools, and it is bottle-for-bottle exchange, that is, when new nitrogen comes, the old bottle will be taken back. For other companies, a deposit of 50 yuan is required for each barrel of bottled water.

The price of a bottle of high-purity nitrogen here is 100 yuan, and a steel cylinder requires a deposit of 1,000 yuan.

The air conditioner is a new one, and it is quite powerful. Less than ten minutes after it was turned on, the temperature in the room dropped to more than 20 degrees Celsius.

Xu Qiu simply cleaned the two laboratories, and after waiting for a while, the people from the gas pipeline company arrived as scheduled.

They came with a group of four people, including Manager Hu who was in charge of liaison before, a middle-aged man who looked like an engineer, and four young guys with toolboxes and pipeline components in their hands.

This group of people is the most company-like among the companies contacted during the establishment of Jiangwan Lab.

Among them, Manager Hu is wearing a very formal outfit, which belongs to the kind of outfit that can be recognized as a salesperson at a glance, with a white shirt, black trousers, leather shoes, and a tie.

Xu Qiu really wanted to ask him: Aren't you hot?

Manager Hu didn't know what Xu Qiu was thinking, so he stretched out his hand and greeted with a smile: Teacher Xu, shall we start the installation?

Xu Qiu shook hands and nodded in response: Okay, let's start.

After all, the four boys who accompanied them began to disassemble the several rectangular boxes they brought, which contained thin metal tubes, one by one, in addition, there were components such as pressure reducing valves, Ω-shaped clamps, etc. .

After the disassembly was completed, the engineer took the previously planned drawings and directed the four younger brothers to start the installation directly.

The installation process is not too difficult. The lines and locations have been planned in advance, and only need to be assembled on site.

While the others were working, Xu Qiu was chatting with Manager Hu.

Your company's business should be good this year. There must be a lot of cooperative research groups in our school. Xu Qiu said casually.

Actually, it's okay, Manager Hu explained. There are about nine orders in the material department, and there are fewer orders in the polymer department, only seven orders.

Is there only nine orders in the material department? Xu Qiu muttered.

Yes, Manager Hu nodded, The materials department is mainly located on the fifth, sixth and seventh floors here, and many of them share a set of air circuits shared by several rooms.

That's it. Xu Qiu replied that the research group of the Department of Materials for centralized gas supply was much smaller than he expected. He thought there were at least a dozen or twenty orders.

But when he thought about it, it was understandable. Although there are more than 80 teachers in the Department of Materials Science and Technology, there are not many research groups active in the front line of scientific research. Some are lecturers and associate professors who do not do scientific research. They have no laboratory and only one office. , and there are several large research groups, and several teachers under them are combined for centralized gas supply. In addition, there are also some groups that do not need to use gases such as nitrogen and argon, such as metals and composite materials, which do not involve synthesis. No glove box.

Afterwards, Xu Qiu asked again, Where are the chemistry and physics departments?

The Department of Chemistry and the Department of Physics, our company did not win the bid, and another company is in charge. Manager Hu smiled awkwardly.

Well, it seems that the competitive pressure in this industry is not small. Xu Qiu nodded and said.

After the two chatted awkwardly for more than an hour, the engineer took a few younger brothers to complete the installation.

Manager Hu took out an acceptance form and said, Mr. Xu, please start the acceptance check. After the acceptance check is completed, you need to sign here.

Xu Qiu nodded, took out a few balloons, tied them with rubber bands to the gas path of the pressure relief valve, and started testing.

The so-called centralized gas supply, the structure is that there is a main valve on the side of the nitrogen cylinder, and then a dozen lines are separated, which are connected to the pressure reducing valves at each point in turn, similar to parallel connection, as long as there is no problem with the main valve, a single point If a problem occurs, it does not affect the normal work of other sites.

The content of acceptance, on the one hand, is to see if they have been installed according to the previous design plan, and on the other hand, to test whether the pipeline is blocked or whether there will be air leakage.

Twenty minutes later, Xu Qiu carefully checked the main valve and the pressure reducing valves at more than a dozen positions, and found no problems, so he signed his name on the acceptance form, and then sent photos of the installation here to Wei Xingsi.

At noon, Xu Qiu went to the cafeteria to take a look. The second floor was still being renovated, so he ate another meal of braised beef noodles, which still tasted familiar and delicious.

After dinner, Xu Qiu walked around the campus again, and found that there was only one teaching building on the Jiangwan side, which was divided into Blocks A and B.

The decoration is not bad, especially the bathroom, the tiles are shiny, giving people a sense of magnificence, which is almost on par with the bathroom in Zhangjiang Microelectronics Building.

The buildings in the Handan campus are relatively old, so the bathroom design is so-so, especially the first teaching building, where the bathroom is an old-fashioned bathroom.

There is a water reservoir on the far side. Pull down the drawstring of the water reservoir, and water will come out from the side, and then wash each pit in turn. After Xu Qiu experienced it at that time, the first thing that came to mind was the flowing water noodles of the Neon Kingdom...

Speaking of which, buildings in colleges and universities are generally not demolished and rebuilt very much. Except for the dangerous buildings that have to be demolished, most of them will choose to renovate.

The first teaching building was refurbished last year. The method used is to tile and repaint the inside and outside. Although this method is very simple, it is really effective. From the appearance alone, it is not too different from the new building. There are many differences. It is worth mentioning that the bathroom decoration is very good.

When Xu Qiu University first entered the university, I saw someone posting evaluation posts on the Internet on the BBS, evaluating the bathrooms of the teaching buildings and office buildings of Shanghai Comprehensive University. Among them, the first teaching building was the one with the lowest score, and He also claimed to have posted comments to the headmaster's mailbox, saying that students in the first teaching are eager for a new bathroom.

Perhaps the renovation of the first teaching was the credit of that classmate?

In the afternoon, Lao Wang from the fume hood came over, and they made a lot of noise.

Because the fume hoods are relatively large and heavy as a whole, it is definitely unrealistic to lift them manually. It needs to be lifted by a hydraulic forklift first, and then transported to room 520 by a freight elevator.

Lao Wang is not fighting alone. He also has two younger brothers. The three of them dress in a more worker style, and they all wear dirty and wear-resistant coarse cloth clothes.

Xu Qiu didn't have to go off in person, he just stood in the 520 laboratory and instructed them to move the ventilation cabinet to the designated position.

It took nearly an hour to unload this time. The cabinets were moved over, and then the water, electricity, gas, and exhaust devices had to be integrated. Of course, because the ports had been reserved in advance, Xu Qiu didn't need to worry about it.

Among them, the installation of water and electricity is relatively simple, and the installation of fans is a little more complicated, which needs to be connected to the exhaust passage on the ceiling.

During the previous design, it was planned to install three fans, one fan was installed on the ceiling to pump the air in the laboratory, and the other two fans were distributed to eight fume hoods, and a row of four fume hoods shared one fan Of course, it is not impossible to install eight fans in eight fume hoods. The main reason is that it is troublesome to install. It is better to integrate them and use two fans with higher power, which is more cost-effective.

At 7:30 in the evening, the organic photovoltaic team gathered at 216 Caiyi to briefly discuss the recent experimental progress.

Wu Shengnan first reported: I synthesized two kinds of IDIC-4F and IDIC-M acceptor materials, brought them back yesterday, and handed them over to Han Jiaying to prepare devices.

Han Jiaying answered: Today I made J2:IDIC-4F, J2:IDIC-M and other systems, and completed the evaporation before dinner, and I can conduct device performance tests later.

Xu Qiu made a high-profile statement: I hope this time the efficiency can make a breakthrough. How about setting a small target, 13%?

Han Jiaying's eyes lit up: Can I get 13% this time?

Tian Qing said with emotion: Xu Qiu, you are so confident.

Chen Wanqing interjected casually: The previous peak was 12.4%, and it is indeed possible to increase it by 0.6% this time. Hey, my world record has only been maintained for a summer vacation, and it was surpassed by you again. The 12.4% data was yesterday The result of the school girl's J2:IDIC system test.

Wu Shengnan made a rational analysis: The performance of J2 material is much better than that of J1. If IDIC-4F or IDIC-M can also be significantly stronger than IDIC, then 13% may really be achieved.

Ma Wenlin is more certain: I think it is very possible to get to 13%.

Several girls chattered and chattered, and Xu Qiu's head grew dizzy. He hurriedly raised his hand: Let's move on to the next topic, Tian Qing, how is your test?

It's relatively smooth. Mo Wenlin and I have completed the test and data fitting of the IT-4F exciton binding energy. The exciton binding energy is 103 millielectronvolts. The data is here... After Tian Qing finished speaking, she put her The laptop screen moved towards Xu Qiu's direction.

Xu Qiu leaned over, browsed the data, found no problem, and said: It seems that IT-4T is comparable to ITIC and IDIC, both of which are on the order of 100 millielectronvolts.

After a pause, Xu Qiu continued: Well, if the system performance of the two derivatives of IDIC can be further improved in the future, Tian Qing and Mo Wenlin, you two, will be responsible for the exciton binding energy and exciton energy of that system. A test of the diffusion distance.

Although Xu Qiu talked about Tian Qing and Mo Wenlin, he was mainly talking about it for Tian Qing, because there was no need for two people to test these two experiments, and Tian Qing was originally in charge, Mo Wen Lin is also responsible for the preparation of devices and ternary blending systems.

Tian Qing heard Xu Qiu's voice, nodded with a smile, and said in a relaxed tone, No problem.
