I Have a Research Support System

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

Before that, they need to pack Zhangjiang's instruments, equipment, and medicines, and then submit the list of hazardous chemicals to be transported to the department for review and filing.

The administrative process in colleges and universities is still relatively complicated. In many cases, it needs to be reviewed layer by layer. There is a stamp here, and a signature there.

And some teachers have a lot of things to do because of the division of responsibilities. For example, Fang Guangwu, the deputy dean of the material department in charge of enrollment, often cannot find others in the office.

Especially in the two months before and after the college entrance examination, it was extraordinarily busy, because the teachers in charge of recruiting students from each department of Shanghai University would be assigned a district, each responsible for the recruiting work of the college entrance examination in the corresponding province.

Before the college entrance examination, you have to go to the key middle schools in the corresponding provinces to hold a publicity meeting, and sometimes you will bring the seniors and sisters from the middle school who have been admitted to the Shanghai Comprehensive University to go there together to play a game of emotional cards;

After the college entrance examination scores, they have to call the top-ranked students to inquire about their intentions, compete with Qingbei University, Shanghai Jiaotong University and other universities, claiming how good are the benefits at our Shanghai Comprehensive University, etc. And offer generous conditions, including cash rewards, tens of thousands of freshman scholarships, and choosing a major at will.

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

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

Every year, there are quite a few people who signed the agreement and then broke the agreement.

Some candidates broke the contract, that is, they signed the agreement and did not apply for the corresponding school, and some schools broke the contract and tricked the student into filling out the application, but in the end the student was not accepted.

Relatively speaking, most of the cases are candidates breaking the contract, but this is not a big loss to the school. Anyway, as a school, it can always recruit students, it is nothing more than better and worse.

There are also a few cases where the school breaks the contract. The admissions teacher usually estimates the score line of this year according to the score line of previous years, and then uses this as a basis to contact the students who exceed the estimated score line.

However, if a black swan event occurs, such as this year’s high-scoring candidates gather to fill in the school’s volunteer application, resulting in the school’s extraordinarily high score, there may be some students who have signed the “volunteer filling agreement” and do not pass the score.

If that student thought it was safe, only filled out one school's volunteer and chose not to accept the transfer, but was not admitted in the end, it would be quite miserable.

After confirming the moving time, 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 leads, there are more boys. After all, this job is considered physical work.

After the school bus arrived in Zhangjiang, everyone went to the drug warehouse and took 18 cartons. The size of each carton was roughly 60*50*40, and the unit was centimeters.

The cartons here are the ones that are pressed together, not the kind of cuboid boxes with edges that need to be made into boxes manually. Therefore, Xu Qiu also used a few rolls of sealing tape.

In addition, Xu Qiu also used materials such as bubble paper and foam fillers to prevent damage to instruments and equipment due to sliding and collision during transportation. After all, a small half of the organic laboratory is full of various bottles and cans. Glass instruments are very easily damaged.

After receiving them, the group headed to the microelectronics building with supplies.

After everyone sat in the office of A501 and paddled for a while, Xu Qiu began to give instructions and divide the work: Wu Shengnan, take Sun Wo, Yan Hu, and Yin Houlang to make cardboard boxes and pack the instruments. , Number the boxes with a marker pen on the top of the boxes, and mark the instruments and equipment inside, don’t seal the boxes first, and finally seal them uniformly.”

Han Jiaying and I are in charge of sorting out the medicines and reagents in the laboratory. Before, Xu Qiu had only read the list of medicines compiled by the school girl, and made a preliminary judgment, but what medicines should be taken away, and what medicines should be treated as liquid waste and solid waste To dispose of it, it is necessary to make a second judgment on the spot, and sort out the list and report it to the department for record.

Okay. Everyone took orders and started to work.

Xu Qiu took the printed sample list and checked the medicines with the junior girl.

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

There are dozens of kinds in total, including BDT, BT, FTAZ, BDD, DPP and other monomer units substituted by bromine or trimethyltin, as well as some PDI intermediates obtained by making 3D-PDI materials before. The laboratory Suzzki The reaction is less, and the borate-substituted monomer is relatively less.

Because the monomer materials used in organic photovoltaics mostly contain large conjugated structures similar to dye molecules, the colors of these materials are relatively rich, such as BDT is a yellow powder, BT is a white crystal, DPP is a purple powder, PDI It's red powder...

Did not see any 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 component, if you want it to appear green, you need to absorb all the light with a wavelength greater than 577 nanometers and less than 492 nanometers, which is relatively difficult to do.

Therefore, to obtain green dyes in industry, the common practice is to mix blue and yellow dyes in a certain proportion to obtain them.

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 it encounters light, acid, alkali, oxygen, oxidant, etc. After the plant dies, the green leaves This is why it fades gradually.

After taking stock of the first class of medicines, Xu Qiu put all the bottles and cans containing the medicines into sealed and dry storage tanks, and refilled them with nitrogen for protection.

Because of the small size of the storage tank, Xu Qiu did not use the big box he had just received, but took the small box left over from the oil bath he bought before, first spread two layers of bubble wrap on the inner wall of the box, and then put it in the box. into storage jars, and finally fill the corners of the void with foam padding for protection.

Next, the second-class medicines, that is, unopened medicines, were also sorted out by Xu Qiu and Han Jiaying, including bottles, barrels of solvents, and square boxes of solid reagents, a total of more than 20 groups.

There was an episode in the middle, when Xu Qiu took inventory and found that there were actually 5 unopened bottles of 500ml toluene in the laboratory, so he casually complained: The usual consumption of toluene is not too big...

Han Jiaying explained embarrassingly: A few days ago when we were doing experiments, the toluene was almost used up... Then I ordered two bottles directly online. Later, the drug warehouse sent the reagents over, and I found out that senior sister Wu Shengnan also ordered them. Two bottles, and later, we discovered that there were still two bottles of toluene hidden in the corner of the reagent cabinet, so there were six new bottles in total, one bottle was opened, and there were five bottles left...

Okay. Xu Qiu could almost restore the scene at that time.

There are too many cabinets for storing reagents in the laboratory. Although each reagent cabinet has a rough classification, the original classification will be messed up after a long time, and sometimes he can't find the medicine.

What's more, if the reagents bought by the laboratory are of the same brand, their reagent bottles are similar in appearance, and it is difficult to distinguish them from the appearance alone, and the words on the label paper with the name of the reagent are very small, accounting for only about 100%. For the area of ​​less than 5% of the total area of ​​the paper, the label must face itself in order to be able to see clearly what reagent it is.

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

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

On the one hand, it is a question of time cost. An experiment may involve ten kinds of medicines. If two or three experiments are carried out a day, it is necessary to record the consumption of medicines twenty or thirty times. If all statistics are accurate, at least an additional Give half an hour of your time.

On the other hand, sometimes it is difficult to calculate how much medicine is actually consumed during the experiment. For example, the solvent that passes through the column is packed in a 4-liter barrel. Use a graduated cylinder to measure the amount of solvent consumed.

Moreover, once someone in the middle of the experiment fails to count the medicines he consumes due to various reasons, the final statistical results will be distorted.

Of course, you can also take stock of all the medicines on a weekly or monthly basis. This is not impossible, but it is time-consuming. Like Xuemei, it took a whole day to sort out the list of Zhang Jiang's medicines. She did nothing that day, but went to count the medicines.

If it is a large research group and there is no shortage of money, it is possible to hire research assistants to make statistics and manage the conditions of instruments and drugs in the laboratory, and carry out inventory and summary every day. The work of the small research group must be shared among everyone in the research group.

Work such as statistics on medicines does not help to produce scientific research results, so it will be regarded as insignificant trivial matters.

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