I Have a Research Support System

After leaving Wei Xingsi's office, Xu Qiu approached Wu Feifei and Duan Yun to discuss the design of the new laboratory.

Xu Qiu also called Mo Wenlin to take the minutes of the meeting, and Han Jiaying was reviewing for the exam, and even went to Zhang Jiang to do the synthesis, so don't bother her.

Xu Qiu said, "Senior Wu Feifei, please tell me first, you are more experienced."

Wu Feifei didn't go around and said directly: "First of all, we need to establish the ownership of the laboratory. There are two rooms 520 and 522. One of them is an organic laboratory, and the other is a device and characterization laboratory. How should we allocate them?"

Xu Qiu answered: "This is a small problem. The two rooms are about the same size anyway. I think I can give the larger 520 to the organic. How about it?"

Wu Feifei nodded to express that she had no objection.

Xu Qiu looked at Duan Yun and asked for his opinion.

"Sure," Duan Yun said casually, "Anyway, I'm graduating in one year. I guess the new laboratory has little to do with me. Leave the drawing to me, and you can decide on the rest."

Mo Wenlin wrote down "520 organic, 522 device plus characterization".

Wu Feifei continued: "After determining the ownership of the laboratory, the next step is to plan the specific details, mainly including the laying of pipelines for centralized gas supply, the specific placement of instruments and equipment, in addition to contacting the production of experimental benches, fume hoods, Decorate and contact moving companies.

Among them, the centralized air supply pipeline, fume hood, and moving company are arranged by the school system. We can directly contact the designated company, and the expenses incurred will also be paid by the school system, which can be regarded as the school’s compensation for the relocation.

However, several other items, including the test bench and decoration, need to be solved by ourselves. "

"Well, record these points first, and when the final plan is established, then contact several of their companies. We can ask Mr. Wei for the test bench and decoration to see if there is any channel. By the way, I will add something... "Xu Qiu continued:

"When I visited Gong Yuanjiang's research group before, I found that their glove boxes are connected in rows, so I plan to design our group's glove boxes with a similar structure, organic spin coating on the left, evaporation test in the middle, and perovskite on the right. spin coating.

On the one hand, it prevents the substrate from encountering air during the transmission process, on the other hand, it also prevents the organic and perovskite solvent atmospheres from contaminating each other, and only needs to add an additional glove box without increasing the budget too much. "

He has tried this strategy in the simulation laboratory before. Although the triple glove box he proposed is relatively poor, the effect is remarkable. The performance of the obtained device is basically equivalent to that of Gong Yuanjiang's triple glove box.

"This idea is good, so we don't have to grab the glove box for experiments," Wu Feifei joked: "Now there are five of you in the organic direction, and I, a weak woman, can't grab you."

"Senior sister, you are joking," Xu Qiu shook his head and said, "Then let's continue our discussion."

"Well... By the way, there is another problem," Wu Feifei said suddenly: "This time the school attaches great importance to the safety of the laboratory, so the cylinders need to be placed in the designated cylinder cabinets, and no objects can be placed around them. The centralized gas supply proposed by the system is also out of safety considerations.”

Xu Qiu asked suspiciously: "Does centralized gas supply have anything to do with safety, and the pressure vessels have not been reduced..."

Wu Feifei spread her hands and said, "I don't know either. Probably after the pipeline is fixed, the phenomenon of connecting pipelines privately can be reduced. Some old laboratories had similar safety hazards before, and now they have been redesigned uniformly. It can be regarded as an attempt to solve these problems from the source. Anyway, the school has established regulations, and we will abide by them for the time being.

Xu Qiu nodded. The school's starting point is indeed good. As for how much effect it can have, he doesn't know, but doing it is better than not doing it well. It will never be resolved.

Wu Feifei continued: "Now we need to determine the location of the steel cylinder first, and then we can confirm how to lay the pipeline."

"Hmm..." Xu Qiu thought for a moment and said, "Let's put the steel cylinders in the 522 device and characterization laboratory. 522 is a big gas consumer. For example, Handan 216 consumes about 20 bottles per month on average. Nitrogen, Zhangjiang Organic's laboratory just fills a nitrogen balloon, it doesn't consume too much nitrogen, and you can't use a bottle in a month."

"Yes," Wu Feifei nodded, "It's best to store the steel cylinders near the door, so that the two laboratories can be easily connected. Xu Qiu, let's start with the cylinders as a starting point and draw a sketch."

Xu Qiu took the experiment notebook and fountain pen from Mo Wenlin's hand, and began to draw.

Referring to the existing Caiyi 216 and Zhangjiang Microelectronics A502 laboratories, including Xu Qiu's occasional DIY in the simulation laboratory, he already has a rough prototype of the laboratory in his mind.

First, Xu Qiu drew a square and marked the positions of the doors and windows as a bird's-eye view of room 522 from the sky.

The architectural drawings I saw at Mr. Wei’s side showed that the room area is more than 70 square meters, so the side length of the square is temporarily calculated as 8 meters.

Then, at the doorway, draw two square cylinder cabinets covering an area of ​​one square meter side by side.

The steel cylinder cabinet can generally store two gas cylinders. The actual shape is rectangular, but when planning, it is necessary to consider the opening of the cylinder cabinet and the entry and exit of the cylinder, so it should be designed as a square.

Then, next to the right half of the steel cylinder cabinet, Xu Qiu planned to use it for characterization testing, so he planned three large experimental benches in a concave shape, which were used to put various optical and electrical testing instruments, such as UV-vis, PL, TRPL, CELIV, EQE, etc.

In the middle space of the concave characters, add a test bench, which can be used for some experimental operations, such as cutting glass pieces, or unpacking express delivery.

Then, a glass partition was erected on the left side of the concave character, dividing room 522 into two.

Among them, the right half is the characterization laboratory just planned, and the left half is the device laboratory.

In the device laboratory, three glove boxes are placed in a row against the wall. The extension of the room is 8 meters, and each glove box is about 2 meters long. With the transfer cabin in the middle, the space is sufficient.

On the left side of the glass wall partition, there is an experimental bench with a sink, on which some ultrasonic cleaners, ozone generators and other equipment for cleaning substrates can be placed.

Finally, place several medicine cabinets in the empty spaces in the device lab.

"It's finished," Xu Qiu let out a long breath, looked at his masterpiece with satisfaction, and said, "Do you have any comments about room 522?"

"The overall completion is good, but..." Wu Feifei added: "We need to list the pipeline locations for centralized gas supply and report to the department."

"Okay, then let's do the math." Xu Qiu began to mutter:

"Each glove box needs a circulation pipeline, a manual gas supply pipeline, and a cleaning pipeline. The evaporation chamber needs an additional gas supply pipeline, and the glove box with a nitrogen gun also needs an extra pipeline. Three or four Twelve, there is a nitrogen gun outside, and two ports are reserved, that is, there are a total of 15 in room 522.

In Room 520 on the other side, because the fume hood provided by the school is relatively small this time, we calculated as 8 fume hoods, each of which needs 1 interface, plus two reserved interfaces, a total of 10 interfaces. Add up to 25 ports, including 22 nitrogen ports and 3 nitrogen-hydrogen ports for regeneration. "

After finishing speaking in one breath, Xu Qiu glanced at Mo Wenlin's experiment notebook, realizing that she had already recorded everything she said, so she couldn't help but look at her a few more times, this guy has something.

Wu Feifei compared Mo Wenlin's record book, digested it, and said: "That's it, anyway, this time the department pays for it, and we don't need to be too frugal. Once this centralized gas supply pipeline is installed It’s more difficult to modify it later, it’s always good to reserve more interfaces.”

"Then I will continue to design room 520." Xu Qiu picked up the pen again and started to draw.

The organic laboratory is relatively easy to plan, and Zhangjiang Microelectronics A502 laboratory can be directly reduced and copied here.

First of all, eight fume hoods are placed against the wall in groups of four, and then two laboratory benches with sinks are placed side by side in the middle of the room, and finally the positions of the oven, vacuum oven, and several reagent cabinets are planned.

After reading the two sketches, Duan Yun made an opinion: "The specific dimensions of the test bench, glove box, oven, etc. need to be measured in detail, including the partition thickness of the previous glass wall."

"Well, it makes sense." Xu Qiu imagined it for a while. If he patted his head and set the size casually, when the time came to move, the instruments would be moved there, but it would be embarrassing to find that they couldn't fit in. They couldn't be split in half. Set it apart.

Xu Qiu turned his head and said, "Mo Wenlin, you are in charge of measuring the dimensions of the various instruments at Caiyi 216, and I will hand over Zhang Jiang's to Han Jiaying later."

"Okay~" Mo Wenlin nodded in response.

"If there is no problem, let's discuss this sketch with Mr. Wei first." Xu Qiu said to the other three.
