Chapter 133: Check the fineness of school girls

　　 At the end of the final defense, Mr. Wei stayed in the venue and continued to listen to the fifth report. After that, there were things like scoring and signing.
　　 Xu Qiu returned to Caiyi 216 directly.
As soon as 　　 entered the door, Han Jiaying greeted him and asked:
　　 "Brother, how are you talking about?"
　　 "It's okay."
　　 "Then shall we go to Zhangjiang for synthesis in the afternoon?"
　　 "Okay, I ate at noon and then took the school bus."
　　 A new round of synthesis experiment has officially started.
　　 It’s just that, in terms of time, today’s past is a bit embarrassing because Xu Qiu will be in class tomorrow morning.
　　 How to choose between experiment and class?
　　 After thinking about it, I'd better choose experiment, then I can only skip class.
　　The main reason is that the degree course of "Nanomaterials" gave almost no help to Xu Qiu.
　　 If you change to courses like "Polymer Condensed Matter Physics" and "Semiconductor Physics", it is worth listening to.
　　……
　　 Nowadays, many colleges and universities are doing curriculum reform, leaving students with more and more independent choices.
　　 Like the Magic City Comprehensive University, it can be regarded as one of the earliest experimental universities for teaching reform.
　　 Including undergraduate enrollment, freshman enrollment is not carried out in accordance with traditional majors, but in the form of a large experimental class, with 500 students in a large class, and the second division is also part of the teaching reform.
　　 In addition, the training plan for each student is also relatively flexible, and there is no fixed timetable.
　　 Except for some compulsory professional courses such as "Mathematical Analysis" and "Organic Chemistry", most of the other courses can be chosen independently, such as six modules, general education courses, and professional elective courses.
　　 Compulsory courses account for less than 50% of the total credits.
　　 Xu Qiu's feeling on this is too unobvious, mainly without comparison, and he doesn't know what it was like before the reform.
　　 On the whole, it's a bit like formal engineering.
　　 But compared to never changing, moving, no matter what the result is, it is a good thing for the development of education after all.
　　 is just frequent changes. For those front-line personnel in charge of educational affairs, it may be more difficult.
　　……
　　 After lunch, the two took the school bus to the Zhangjiang campus.
　　 The next work is more repetitive.
　　 After all, almost all the innovative parts were completed by Xu Qiu.
　　 For innovative work, one more person may not improve work efficiency too much.
　　 For highly repetitive jobs, one more person is a solid labor force, and the work efficiency can be approximately doubled.
　　 Of course, the prerequisite is to train Han Jiaying to become a skilled worker.
　　Because when he did the synthesis experiment before, he always let her watch by the side, but he never let her play.
　　 So now she is doing synthetic experiments, and her experience in this area is almost zero.
　　 As for the preparation of devices in her glove box at the Handan campus, they are all appetizers, which is not very difficult.
　　 Like Xu Qiu, he learned everything in less than two weeks. It can be said that he has a hand.
　　 But doing synthetic experiments is different and more difficult. It is still a test of a person's operational skills and experimental talent.
　　 Han Jiaying’s project is to synthesize PBT2T, 3T and 5T series polymer donors.
　　 Xu Qiu originally planned to let her help him synthesize materials first.
　　 But after thinking about it, this time I plan to dose about 500 mg of monomer at a time, which is three times the amount of the previous experimental dose.
　　 If the school girl loses her hand and messes up, the loss will be too great.
　　Senior sister asked him to synthesize the same material, 500 mg.
　　 After consideration, he finally decided to let the school girl do her own three series.
　　……
　　 The two enter the A502 laboratory.
　　 The experimental process, he has already explained to Han Jiaying, the next step is to directly operate it.
　　 It's time to check the fineness of the school girl.
　　 Wear protective equipment, build equipment, and re-evaporate toluene.
　　While waiting, Xu Qiu began to introduce precautions.
　　 There are still many points to pay attention to. These are all valuable experiences summarized in previous experiments.
　　 For example, to apply vacuum silicone grease to improve sealing, how to control the amount of solvent added, etc.
　　 There are also some laboratory safety details, such as wearing multi-layered gloves, using lab coats with elastic cuffs and so on.
　　 Xu Qiu is going to perform a complete operation of the entire reaction process, as a demonstration for the school girl.
　　Unexpectedly, Han Jiaying took the initiative to say:
　　 "Brother, can I conduct experiments simultaneously with you?"
　　 "Yes, so confident." Xu Qiu said.
There should be no problem.
　　Although he agreed, but I still feel uneasy.
　　 So, he was doing experiments while observing the school girls.
　　 Of course, the main thing is to see if there are any problems with her experimental operation.
　　 For Xu Qiu, this experiment is already very skilled.
　　 As long as it is not a critical step, even if it is one mind and two purposes, it will not affect the overall experimental process.
　　 While the school girl started the experiment, she was very focused.
　　 Xu Qiu looked at it for a while, looked up, and found that her face was still slightly red.
　　 Although it's autumn now, doing experiments is still more stamina, maybe because of heat.
　　 observed for a while, he found a few small problems in the school girl’s experiment, and directly pointed out:
　　"Large rubber gloves are too big for you, and it is not convenient to wear them for experiments. You can wear two layers of small ones, or get a few packs of medium-sized gloves.
　　 Another thing is to stopper the bottle stopper in time after weighing the monomer medicine to prevent dust from falling in, or accidentally overturning the bottle and spilling the medicine. "
　　 "Okay, I understand." Han Jiaying finished speaking, her face seemed to turn redder.
　　 It's just that Xu Qiu didn't notice so much.
　　 While experimenting, he compares his senior sister and senior sister in his mind.
　　 In comparison, considering the experimental speed ~EbookFREE.me~Han Jiaying's experimental ability is stronger.
　　 As for other aspects, such as whether the experimental operation is stable, and the physical fitness, it remains to be observed.
　　……
　　 Xu Qiu’s first response was over. He probably estimated that it was more than ten minutes faster than Han Jiaying.
　　 He did not rush to vote for the second batch, but patiently waited for her experiment to end.
　　 Twelve minutes later.
　　 Han Jiaying finished the reaction and heated the oil bath to 130 degrees Celsius, covering it with aluminum foil.
　　 Then, he asked expectantly:
　　 "Brother, how is my performance?"
　　 "Very good." Xu Qiu encouraged:
　　 "In terms of experimental talent alone, it's about the same as me."
　　 "Really, great, brother is my goal afterwards." Han Jiaying said:
　　 "One day, I will surpass you." After she finished speaking, she shook her fist.
　　 "Haha, then I am looking forward to that day." Xu Qiu smiled.
　　 Next, the two continued to react.
　　 Xu Qiu just voted for the reaction, the target product is PBT4T, and then he plans to help the senior sister vote for her three systems.
　　 And Han Jiaying continued to invest in her other two systems.
　　 As for the other four in Xu Qiu's own system, the equipment is really limited, so I can only do it next time.
　　 However, even if the equipment allows, you can cast eleven responses at a time, and the subsequent post-processing is troublesome, and you can't handle it at all.
　　 After all, this is reality, not in a simulation laboratory.
　　 In the evening, the experiment ends.
　　 Xu Qiu sent Han Jiaying to the school bus and told her to come to Zhangjiang early tomorrow, while he stayed in Zhangjiang as usual.
　　 After the inspection, the school girl's condition is not bad.
