Chapter 259: "Reverse Money"

With the U disk and the red-covered doctoral dissertation, Xu Qiu went to 218 and proactively reported to Wei Xingsi: "I have finished reviewing this dissertation."
"Oh? So fast, how did he write?" Wei Xingsi took the U disk and inserted it into the computer.
"Four SCI and one work, mainly doing the PDI system," Xu Qiu briefly introduced the other party's four tasks: "First, modify the side chain..."
After introducing the work content, Xu Qiu concluded:
The overall is not bad, and the articles are written systematically. After all, I have published SCI papers. I can’t pick out any major faults. I only found some writing errors and some The font of the picture is too small, and the transition of the introduction part is not round. I have marked the corresponding page number, line number, and revision comments in the review comments."
Wei Xingsi listened and browsed the review comments on the USB flash drive. Finally, he nodded and said, "Yes, it's a hard work."
After that, he picked up an envelope from the table, handed it to Xu Qiu, and explained: "This is the paper review fee they gave. Since you helped the review, I will give it to you."
"Okay." Xu Qiu took it directly. He knew that Wei Xingsi didn't care about money, and that Teacher Wei went straight and didn't play imaginary, so as long as he did his job well, he would take the rewards he should get. , And generally wouldn't be polite with him.
"By the way, how is the sample preparation for TAS?" Wei Xingsi asked casually.
"The solution is prepared, and the quartz glass can be used at the material office tomorrow, and samples can be prepared." Xu Qiu replied.
"Okay, go ahead." Wei Xingsi waved his hand.
Leaving 218, in the corridor, Xu Qiu looked at the envelope in his hand, with an unopened adhesive strip on the edge.
I squeezed it casually, it was still slightly thicker.
Xu Qiu carefully tore open the rubber strip, poured out the banknotes inside, and counted them.
Oh, there are five hundred yuan bills.
More than expected.
Unlike SCI paper review, there is a review fee for this kind of graduation thesis review. Generally, it may be two to three hundred for master's degree and three to five hundred for doctoral degree. Different schools may have different standards, but they will not deviate too much. Usually, you have to wait. After the graduation process is completed, the reviewer will be paid through the school reimbursement.
For reviewers at this level of professors, spending most of a day reviewing a graduation thesis and earning a few hundred yuan can only be described as "hard money".
The key point is that after the evaluation, the money is not settled, and one or two months have to be waited. This is a bit of insincerity. Therefore, some teachers will advance the money in advance and put an envelope directly when mailing the paper. Like this one in Xu Qiu's hands.
This kind of operation is a bit similar to "reverse element money". This year my students graduated, and I will give you a few gifts, and next year your students graduate, you are giving me the same gifts.
Xu Qiu returned to 216, and Han Jiaying, who was in the codeword state, suddenly stopped and said, "Brother, do I need to test TAS for my system?"
"Um..." Xu Qiu thought for a moment, and said, "You can prepare some samples, please ask Feng Shengdong to test it, and I will say hello to him later."
"Okay~" Han Jiaying stretched her waist in the direction of Xu Qiu, "Then I'm going to prepare the solution. After sitting for a long time, I feel stiff."
"Go ahead." Xu Qiu nodded and edited a message to Teacher Feng Shengdong, "Our group has another system, and I also want to test TAS, okay?"
I soon received a reply from Feng Shengdong, "Yes, just send it in batch with your samples, and the address is...".
Then there was another message, "I have read the results of TRPL, the overall analysis is good, but you can add some content, then I will finish the TAS test, and write it to you together. You can integrate it into the text. "
This time is a bit similar to the situation when Tang Yunkun wrote a review before. People in different fields have different expression habits when writing articles, and the written text needs to be revised and polished.
In particular, Mr. Feng Shengdong mainly studies the mechanism of inorganic aspects, and the gap in language style is even greater. For example, they will mention "conduction band" and "valence band" for inorganic, but they usually talk about HOMO/LUMO energy level when changing to organic.
If you don't add any polish, a "conductor band" appears directly in the article, and if you run into a more serious reviewer, it is not impossible to kill the article directly for you.
At this time, Chen Wanqing came out of the inner laboratory, washing her hands, and discussing today’s device results with Xu Qiu:
The PCE10 system still has not broken through 4%. The PTAZ system tested four devices and the highest efficiency was 3.5%...

Xu Qiu compared the preparation conditions of the senior PTAZ system with the best conditions in the simulated experimental system, and suggested: "Senior, you can try hot spin coating and solvent additive DIO." In fact, DIO is the core optimization. The plan, but for the sake of insurance, Xu Qiulalai used the hot spin coating with no improvement effect as a smoke bomb.
"Yes, I'll try it tomorrow." Chen Wanqing shook her hand in the sink, wiped it dry with a roll of paper, and returned to the desk, saying: "I will contact them to buy 200 mg of the material first, and I will almost use up the PTAZ samples. ."
"By the way, the senior sister doesn't plan to develop the next generation of A-D-A materials?" Xu Qiu asked casually.
"Get the data of the IDT-ICIN system first, and do the synthesis while writing the article, just like Han Jiaying is now." Chen Wanqing paused, and continued: "The next step is to optimize the molecular structure and increase the difficulty. Many, whether it is the optimization of the central D unit or the optimization of the ICIN unit, it involves three or four steps, or even five or six steps."
Xu Qiu joked: "I still remember the elder sister's ten-step synthesis in the first place, and she didn't even frown when she did it. Why are you so confused now?"
Chen Wanqing shrugged and said, "Isn't that educated."
...
The next day, Monday.
After Xu Qiu sent Han Jiaying to the school bus, he went directly to the materials department to receive quartz glass sheets, and by the way, he also took a few packs of disposable PE gloves, disposable syringes and other laboratory consumables, and then walked in the direction of the materials.
There is no need to hold a group meeting today. People are quite lazy. When Xu Qiu arrived at the 216 gate at 9:22, he found that he was the first to arrive.
With the supplies in her arms, Xu Qiu took out the campus card in an extremely distorted posture, swiped the entrance guard, and entered the room.
After placing the used consumables in the laboratory cabinet, Xu Qiu took out 45 pieces of quartz glass and installed them on the holder, put them into a beaker containing isopropanol solution, and started ultrasonic cleaning.
After cleaning, Xu Qiu took the quartz glass sheet with tweezers, dried it with a nitrogen gun, treated the substrate surface with ozone, and transported it to the spin coating glove box.
Subsequently, replace the suction table of the small-size homogenizer, spin-coat, put the sample into a plastic bag, mark the number on the plastic bag, and seal it with a vacuum laminator.
A total of 13 groups and 39 samples were obtained.
Including 3 blank samples, Xu Qiu 21 samples, Han Jiaying 15 samples.
During the entire spin coating process, Xu Qiu has been cautious.
After all, this piece of quartz glass with an area of ​​one square centimeter, not as big as a fingernail, costs about 5 yuan to receive it. If it is a piece of scrap, one is more cute than it is.
Fortunately, Xu Qiu's spin coating skills are now very superb, and there are no mistakes. After one time, he netted 78 cute ones, which is enough for him and her for a year.
After preparing the sample, Xu Qiu called Chen Wanqing to hand over the right to use the glove box to the senior sister.
Chen Wanqing began to prepare a new batch of devices, and Xu Qiu called the agent of DHL express company to make an appointment for pick-up in the afternoon.
The four major international express companies are DHL, UPS, TNT and FEDEX. For small samples, it is generally the most cost-effective to take DHL, which can be delivered within 2-5 working days, and the courier fee is not expensive, and charges are based on weight. For a package weighing 0.5 kg to Sweden, the shipping cost is about 104 yuan, and for a 1 kg package to Sweden, the shipping cost is about 120 yuan...
Although Xu Qiu's samples are quite large, there are as many as 39, but they all weigh less than 1 kilogram.
After two o'clock in the afternoon, the courier brother came to pick up the package on time, and Xu Qiu handed the packaged samples to the other party.
"What is this I want to send?" The courier brother observed the buzzing equipment in the laboratory, and suddenly felt that the thing in his hand was not simple.
"It's mainly quartz glass." Xu Qiu answered truthfully. When he saw Feifei Wu sending samples in China, Brother He Shunfeng said that the solid samples she sent were documents, and the other party received them directly, but now his This kind of international express delivery has to go through customs. It is better to tell the truth. Although there is a film on it, it is not deceiving to say that it is mainly quartz glass.
"This thing is not toxic?" The courier brother asked again.
"Don't worry, it's not toxic." Xu Qiu vowed, which is also the truth. The coated film is mainly 3D-PDI molecules and P3TEA. The former is a dye molecule and the latter is a polymer, which is almost non-toxic to the human body. , Unless you die for a bite...
"Okay, let me weigh it." The courier brother didn't suspect he was there, picked up the portable electronic scale he carried, and started weighing ~EbookFREE.me~ Well, a total of 816 grams, and the charge is 150 yuan. "
"The price has increased?" Xu Qiu remembered that the previous inquiry was around RMB 120.
"Well, the price listed on the website is a reference price, which will change at any time." The courier took a photo of the sample, then put the sample in the file bag and said, "Please check the address again."
Xu Qiu didn't care about the price. He looked at the address on the list. After checking, he took out two hundred-yuan bills from his pocket and said, "The address is no problem. I will pay in cash."
"I'm looking for you at fifty." The courier guy pasted the document bag, handed Xu Qiu a receipt, and left immediately.
After asking Teacher Wei to reimburse the courier expenses, Xu Qiu came back to take over Chen Wanqing's device preparation work and began evaporation.
The elder sister was able to take the time to supplement various representations.
In the evening, Xu Qiu finished testing the senior sister's device.
The highest efficiency, 5.19%!
