Chapter 78: Registration

　　 "I can give you 82 points for this operation, and the remaining 18 points will be given to you by 666." Chen Wanqing said.
　　 She looked at the quotation and found that this page was basically a monomer of the thiophene family.
　　The difference lies in the number of thiophenes and the type and position of the branch.
　　 Is he planning to make it big and comprehensive?
　　 Chen Wanqing thought about it, and planned to contact the manufacturer's QQ, but Xu Qiu snatched the mouse.
　　 "Wait, there is this page, this and this are 1 gram," Xu Qiu said:
　　 "Except for these three, all the other monomers are 200 mg each."
　　 "Uh...is there any more?" Chen Wanqing said helplessly.
"Gone."
　　 "All right, I will try to help you ask."
　　 Chen Wanqing sent a message to the sales inquiry, but did not receive a reply immediately.
　　 Seeing this, Xu Qiu did not wait.
　　 He went to the laboratory to test the stability of the device. This experiment was tested twice a day.
　　 After more than twenty minutes, the test is over.
　　 "Sister, is there any news?" Xu Qiu asked.
　　 "Well... At first, they were unwilling. Later, we came to see that we bought a lot of them, and they reluctantly agreed." Chen Wanqing said:
　　"My system bought three kinds of monomers, a total of three grams, and your system bought nearly 20 kinds of monomers.
　　 However, we spent almost the same amount of money, about 5,000 yuan, and spent a total of 98,000 budget. "
　　 "When I designed the molecule, I chose a unit with a relatively simple structure, and it is normal to be cheaper." Xu Qiu said:
　　" In other words, the molecular structure of these monomers is not complicated. Can we synthesize it ourselves?
　　 But I see that more than 80% of the literature does not have a step for synthesizing monomers, but just gives an equation for the polymerization reaction. "
　　" If you synthesize by yourself, you can, but the synthesis cycle is too long, and reactions like adding fluorine atoms to monomers and adding trimethyltin are more dangerous.
　　 Therefore, most small research groups buy ready-made monomers from optoelectronic materials companies and then do polymerization.
　　 There are only a few large research groups specializing in organic photovoltaics. They have a large number of people and can arrange for division of labor. Several people specialize in synthesis, a few people make devices, and a few people make optimization. "Chen Wanqing said.
　　 "Understood, it's like an assembly line." Xu Qiu said.
　　 "Almost, for large research groups, most graduate students don't actually have too many research ideas of their own," Chen Wanqing said:
　　"They are just trained to be skilled in experimenting'skilled workers' to help their instructors realize their ideas.
　　 However, a small research group like ours has only one worker and cannot build an assembly line even if it wants to.
　　 Before, I was the one who silently resisted everything.
　　 But now..."
　　 "Now it's harder for you, and you have to fight one more me." Xu Qiu interrupted.
　　Chen Wanqing:...

A few days after 　　, Xu Qiu and Chen Wanqing wrote articles together and changed the article. He also added two small experiments.
　　 Xu Qiu has plans to start synthesizing monomers from scratch. After all, there are too many restrictions on buying other people's things.
　　 But considering the toxicity of drugs and the risk of experiments, he asked the system:
　　 "The system, will the use of toxic reagents in the simulation laboratory cause poisoning or explosion, will this effect be transmitted to the real world?"
　　 [No, the host enters the simulation laboratory in the form of projection, which is not related to the host in reality. 】
　　 That's good, it seems that if you have any thoughts of death later, you can also try the water in the simulation laboratory first.

　　 Friday afternoon.
　　 This article about the perovskite transport layer is basically written.
　　 Regarding the first author of the paper, after discussion, the two decided to work together. Chen Wanqing ranked first and Xu Qiu ranked second.
　　 From the article level, a total of one shows that the two people contributed equally to this work.
　　 But at the school level, there are a total of first authors, and in most cases they are considered the first authors.
　　Only when the scholarship is evaluated, the two will share the score represented by the paper.
　　 However, Xu Qiu didn't care too much about the gains and losses. In other words, he also picked up a lot of skills from the senior sister, and some of them should be returned.

on Saturday.
　　 After working for five consecutive days, a rare day off, after Xu Qiu and Tao Yan had lunch together, they returned to the bedroom, lay on the bed, opened the starting point, and read a novel.
　　 After a while, there was a noise at the door. It turned out to be Ren Bin, who was still holding a suitcase in his hand.
　　 "Binzi, I'm back." Tao Yan said.
　　 "Tao Yan, Xu Qiu, you are all here." Ren Bin said.
　　 "The two of us returned to school half a month ago, but you, you didn't pass your course last semester." Tao Yan said.
　　 "This is not the result of the pre-examination surprise, but also thank you and Xu Qiu," Ren Bin smiled:
　　 "By the way, how did you know that I didn't pass the course?"
　　 "The make-up exam started last week. If you didn't come, it means you didn't pass the exam. You were back to school early every semester," Tao Yan said:
　　 "Binzi, you just want to say thank you?
　　Is there nothing practical?
　　 Anyway, I also gave you hundreds of trillions of review materials~EbookFREE.me~ of course. "Ren Bin clapped his hands, opened the suitcase, and while taking out his things, he introduced:
　　 "Raisins, almond wood, and specialties of our Xinjiang province, cut a catty of cake."
　　 "Brother is good, it didn't hurt you in vain." Tao Yan put down the game console in his hand, jumped out of bed, and said to Xu Qiu:
　　 "Xu Qiu, come down to share snacks."
　　 Xu Qiu had just finished eating, was not very interested in the food, and did not want to move when lying on the bed, and said:
　　 "You can figure it out by yourself, just leave me some."
　　 After dividing the snacks, Ren Bin said, "Is it necessary to register this Sunday?"
　　 "Yes, school starts on September 1, so register tomorrow on August 31. The location will be the same as usual, at the department office of the East Main Building of the Twin Towers." Tao Yan said.
　　Madu Comprehensive University starts on the first Monday in March and September every year, and register on the Sunday of the previous day.
　　 This year coincides with September 1st, which is a Monday. In previous years, school may not start until September 6th.
　　…………
　　 On Sunday morning, Xu Qiu went to the department office to register.
　　 When I was in the elevator on the way, I ran into some acquaintances and classmates.
　　 The registration process is very simple, you only need to swipe the campus card, and then put a stamp on the student ID.
　　 However, you must be there in person. If you cannot arrive, you need to ask the counselor for leave in advance.
　　 If you need to buy student tickets, it will be a little troublesome. You need to leave your student ID and the department will go to the department to add magnets.
　　 You can buy student tickets four times a year. If you don’t use up, you can keep the number of times.
　　 If you run out, you must go to magnetism before you can continue to buy student tickets.
