I Have A Research Support System - Chapter 415

On Wednesday morning, Xu Qiu contacted the moving company by phone according to the contact information of the moving company given by the department and made an appointment for Zhang Jiang’s specific moving time next Tuesday.

Before that, they need to pack Zhang Jiang’s equipment, equipment, and medicines first, and then submit the sorted list of hazardous chemicals to be moved to the department for review and filing.

The administrative process in colleges and universities is quite complicated, and many times it needs to be reviewed at different levels. A stamp is placed here and a word is signed there. If the head of the department happens to be absent when the signature is required, it is still very troublesome.

Some teachers have a lot of things because of the division of responsibilities. For example, Fang Guangwu, the deputy head of the Department of Materials in charge of enrollment, often finds no one else in the office.

Especially in the two months before and after the college entrance examination, it was extremely busy, because the teachers responsible for enrollment in each faculty and department of Mordu Comprehensive University were assigned a district, each responsible for the college entrance examination in the corresponding province.

Before the college entrance examination, you must go to various key middle schools in the corresponding provinces to hold publicity meetings, and sometimes you will bring the seniors and sisters of the middle school who are admitted to the Magic University to go there and play an emotional card;

After the college entrance examination scores, they have to call the top-ranked students to inquire about their intent, and compete with Qingbei University, Modu Jiaotong University and other universities, claiming “how is the welfare of our Modu Comprehensive University” and so on. And offer generous terms, including cash rewards, tens of thousands of freshman scholarships, and random selection of majors.

In addition, sometimes the teacher in charge of enrollment will sign a “volunteer registration agreement” with the candidates in advance, that is, the candidates make a promise to fill in with XX University as a volunteer, and the school makes a promise that the corresponding candidates will be admitted.

Of course, this “voluntary filing agreement” has no legal effect. Although it is a written document, it is more like an oral agreement.

Every year, many people sign agreements and even break them.

Some of the candidates broke their contract, that is, they signed the agreement not to register for the corresponding school, and some of the schools broke the contract and fooled the student to fill in the volunteers, but in the end the student was not accepted.

Relatively speaking, in most cases, test takers break their contracts, but the loss to the school is not great. Anyway, as a school, students can always be recruited. It is better than worse.

There are also a few cases where the school breaks the contract. The admissions teacher usually estimates this year’s score line based on the previous year’s score line, and then contacts students who exceed the estimated score line on this basis.

But if there is a black swan incident, such as this year’s high-score candidates get together to fill in the school’s volunteers, causing the school’s score line to be exceptionally high, it may happen that some students who have signed the “volunteer filling agreement” have not passed the score line.

If the student feels foolproof, only fills in a school’s wish and chooses not to accept the transfer, and in the end he is not admitted, it would be more miserable.

After determining the time to move, Xu Qiu directly took Han Jiaying, Wu Shengnan, Sun Wo, Yan Hu, Yin Houlang and others on the school bus to Zhangjiang Laboratory.

Among the people he brought, there were too many boys. After all, this job was considered physical work.

After the school bus arrived in Zhangjiang, everyone first went to the drug warehouse and received eighteen cartons. The size of each carton is roughly 60*50*40, and the unit is cm.

The cardboard boxes here are the kind of cardboard boxes that are pressed together, not the kind of rectangular parallelepiped boxes with ribs. You need to manually make them into boxes. Therefore, Xu Qiu also took a few rolls of box sealing tape.

In addition, Xu Qiu also used bubble paper, foam fillings and other materials to prevent damage to instruments and equipment due to sliding or collision during transportation. After all, a half of the organic laboratory is made of various bottles and cans. Glass instruments are very easy to damage.

After receiving the materials, the group headed to the microelectronics building with the materials.

After everyone sat in the office of A501 and paddled for a while, Xu Qiu began to give instructions to divide the labor: “Wu Shengnan, you take Sun Wo, Yan Hu, Yin Houlang and the others to make cartons and pack the instruments. Pay attention to the packaging. , Use a marker on the box to number the box, and mark the instruments and equipment inside. The box should not be sealed first, and finally sealed uniformly.”

“Han Jiaying and I are responsible for sorting out the medicines and reagents in the laboratory.” Xu Qiu just looked at the list of medicines collected by the school girl before, and had a preliminary judgment, but what medicine should be taken away and what medicine should be treated as waste liquid or solid waste. To deal with it, a second judgment on the spot is needed, and a list is compiled and submitted to the department for filing.

This book is organized and produced by the public account. Follow VX [Book Friends Base Camp~www.mtlnovel.com~ to receive cash red envelopes!

“Okay.” Everyone took orders to start work.

Xu Qiu took the printed sample list and checked the medicine with her school girl.

The first is a class of drugs, that is, high-value drugs.

There are dozens of kinds, including various types of bromine or trimethyltin substituted BDT, BT, FTAZ, BDD, DPP and other monomer units, as well as some PDI intermediates obtained from 3D-PDI materials. Laboratory Suzzki There are fewer reactions, and there are relatively few monomers substituted with borate esters.

Because most of the monomer materials used for organic photovoltaics contain large conjugated structures similar to dye molecules, the colors of these materials are relatively rich. For example, BDT is a yellow powder, BT is a white crystal, DPP is a purple powder, and PDI It’s red powder…

But there is no green material.

Green is relatively common in life, and most higher plants on land are green.

However, in Xu Qiu’s impression, green materials in the laboratory are relatively rare.

He speculated that it might be because the wavelength of green light is in the middle of visible light, which is about 492-577 nanometers.

If it is a pure substance with a single composition, if you want it to appear green, you need to absorb all the light with wavelengths greater than 577 nanometers and less than 492 nanometers, which is more difficult to do.

Therefore, in order to obtain green dyes in industry, a common method is to mix blue and yellow dyes in a certain proportion.

Of course, there are also green dyes developed based on pigments in plants, which are usually complexes containing metal ions such as magnesium and copper.

Natural chlorophyll is a complex containing magnesium ions, but this complex is not very stable. Free chlorophyll will decompose when exposed to light, acid, alkali, oxygen, oxidants, etc. After the plant dies, green leaves It will gradually fade for this reason.

After counting the first class of drugs, Xu Qiu put all the bottles and cans of the drugs into sealed and dry storage tanks, and refilled them with nitrogen protection.

Because of the small volume of the storage tank, Xu Qiu did not use the large box that he had just picked up. Instead, he took the small packing box left behind by buying the oil bath before, and put two layers of bubble wrap on the inner wall of the box before putting it. Put it into the storage tank, and finally fill the corners of the gap with foam padding to provide protection.

Next, the second-category medicines, the unopened medicines, were also organized by Xu Qiu and Han Jiaying, including bottled, barreled solvent and square boxed solid reagents, a total of more than 20 groups.

There was an episode in the middle. Xu Qiu found out that there were 5 unopened bottles of 500ml of toluene in the laboratory, and he said casually: “The usual consumption of toluene is not large…”

Han Jiaying explained embarrassingly: “When we were doing the experiment a few days ago, the toluene was almost used up… Then I ordered two bottles directly online, and later the drug warehouse sent the reagents over, and I found out that the male sister Wu Sheng had also ordered it. Two bottles. Later, we discovered that there were two useless bottles of toluene hidden in the corner of the reagent cabinet, so there were six new bottles in total, one bottle was opened, and five bottles remained…”

“Okay.” Xu Qiu can almost restore the scene at that time.

There are too many cabinets for storing reagents in the laboratory. Although each reagent cabinet has a general classification, over time, the original classification will be messed up, and sometimes he may not find medicine.

Moreover, if the reagents purchased in the laboratory are under the same brand, their reagent bottles are similar in appearance, which is difficult to distinguish from the appearance. The words on the label with the name of the reagent are very small, about The total area of ​​the paper is less than 5%, so you must have the label facing you so that you can see exactly what reagent is.

Xu Qiu has always wanted to design a very simple label, which is simply a piece of white paper, with the largest font size written on the Chinese name of the reagent, and everything else is simplified. Of course, this is just thinking about it, and it is actually impossible to achieve.

In addition, ideally, each drug in the laboratory should be recorded when it is used, so that combined with the purchase data, you can know the real-time inventory quantity in the laboratory. But in actual use, it is difficult to do this.

On the one hand, it is a matter of time cost. An experiment may involve ten kinds of medicines. If two or three experiments are carried out a day, then the consumption of medicines must be recorded 20 or 30 times. If all the statistics are accurate~www.mtlnovel .com~ At least an additional half hour is required.

On the other hand, sometimes it is difficult to figure out how much medicine is actually consumed during the experiment. For example, the solvent used to pass the column is in a 4 liter barrel, and the consumption is very inaccurate by visual inspection. Use a graduated cylinder to measure the amount of solvent consumed.

Moreover, once a person is doing an experiment in the middle of the experiment, for various reasons, he does not count the medicines he consumes, then the final statistics will be distorted.

Of course, you can also check all the medicines every week or every month. This is not impossible, but it takes time. Like the school girl, it took a whole day to sort out the list of Zhang Jiang’s medicines. She didn’t do anything on that day, she just went to count the medicines.

If you are a large research group and you are not short of money, you can hire research assistants to count and manage the equipment and medicines in the laboratory, and take inventory and summary every day. The work of the small research group must be shared among everyone in the research group.

Statistics, such as drugs, do not contribute to the production of scientific research results, so they will be regarded as trivial things.

If the boss doesn’t mention it, everyone’s willingness to take the initiative is not high.
