Chapter 135: Mature tool man

　　 The next day, Xu Qiu checked the two reactions of the supplementary shot, and both were normal.
　　 This shows that the failure of the previous experiment is probably caused by accidental factors, rather than a key problem.
　　 In the next experiment, Xu Qiu continued to teach Han Jiaying the post-processing:
　　 includes operations such as dripping methanol solvent, three mixed solvent Soxhlet extraction, chloroform Soxhlet extraction, and rotary steaming.
　　 Except for the chloroform solvent extraction, which was done by him, other experiments were done by the school girls.
　　 The two happily spent three days in the two-person world in Zhang Jiang's laboratory.
　　 By Thursday night, the two batches of synthesized seven materials were all processed.
　　It is good to be happy that the yields of the final products are all good, fluctuating between 50%-70%, and the yields of crude products even reach 80%-90%.
　　 Several reactions of Xu Qiu's synthesis have obtained more than 300 milligrams of materials, which is enough for a period of time.
　　 Moreover, after several days of observation, he found that the overall performance of the school girl is excellent.
　　 It seems that Han Jiaying's amazing performance on the first day of synthesis in Zhangjiang was not a flash in the pan, but sustainable.
　　 That is to say, her experimental ability is still stable, the volatility is relatively small, and it will not get better and worse.
　　 This is a treasure.
　　 Pack two batches of materials and return to Handan campus.
　　 On the school bus, the two were sitting in the back row of seats.
　　 "It's really hard work to do synthesis experiments. It takes seven or eight hours of continuous experiments," Han Jiaying exclaimed:
　　 "By the way, brothers have been in Zhangjiang for two nights, how do you feel?"
　　 "I'm used to it. Anyway, there is a bed with air-conditioning, and living in it is no different from the bedroom," Xu Qiu said:
　　 "It's you. If you chose the second path before, mainly making devices, you only need to be in Handan most of the time. It will be relatively easy."
　　 "Hey, I was tricked into getting on the thief ship." Han Jiaying sighed.
　　 "You can't talk nonsense," Xu Qiu explained quickly:
　　 "You can't rely on me, you choose the path of synthesis.
　　By the way, you have just entered this field now, and the boat is good to turn around.
　　 If you think it’s not appropriate, you can change the direction, or even go and do perovskite with Feifei Wu.
　　 Let me talk to Teacher Wei, he will most likely agree. "
　　 Although he is not willing to be such a talented student girl, he still has to do his responsibilities as a senior, and he still has to give reminders.
　　 "Hey, brother, I'm kidding, you just don't want me to do it with you." Han Jiaying smiled.
　　 "It doesn't mean that, it's just a suggestion for you." Xu Qiu said.
　　 "Hmm... that's good, although the synthesis is hard, the experiment is still very interesting." Han Jiaying said:
　　 "If I can synthesize a new material in the future and name it after myself, it would be very fulfilling."
　　 "Let's work hard together." Xu Qiu encouraged.
The idea of ​​　　 school girl is still quite ideal, and he did not say anything to attack her. It is still very good for the scientific researcher to maintain a passionate heart.
　　 As for the ideal, after she has experienced more, her thoughts may change accordingly.
　　 Just like him, his feelings about scientific research have been changing all the time in just six months.
　　 However, judging by the enthusiasm and talent shown by the school girl now, she does it with herself, at least there is no problem with graduation.
　　……
　　 In the next few days, the main task is to supplement the experimental data according to the requirements of the article.
　　 trained Han Jiaying for more than a month, now is the time to harvest.
　　 Xuemei has basically become a teacher and has evolved into a mature tool person.
　　 Give her an experiment instruction, and you can get the results of the experiment without much care.
　　 Xu Qiu was also able to escape from the repetitive experimental work and concentrate on writing articles.
　　 Ideally, you only concentrate on writing articles. Most articles can be completed in one to two weeks. Even a long review article can be completed within a month.
　　 He currently has two more jobs, so he can complete them in half a month to a month.
　　 Of course, in the real world it is not so ideal.
　　 On the one hand, it is written that the experimental data may be found to be wrong.
　　 Just like when Chen Wanqing tested the light absorption spectrum, there is nothing wrong with taking out each graph and each curve separately, but they don't fit well together.
　　 In this case, a supplementary test is required.
　　 On the other hand, if you write too many articles, there will be refractory periods.
　　 From the perspective of symptoms, it is similar to the refractory period.
　　 put his hand on the keyboard, there seemed to be all kinds of thoughts in his heart, but he just couldn't type a word.
　　……
　　 Time flies by, and in a blink of an eye, the next Monday is the day when the department organizes production internships.
　　 For Xu Qiu, it was quite embarrassing to choose this time. If it was earlier, the gathering would start in the morning.
　　 Then the time of the group meeting can be covered, and he can also ask for leave for the group meeting just as well.
　　 However, the time is set in the department, and it must not be changed.
　　 had to participate in the group meeting first, and then go to catch the bus.
　　 He also hopes that the group will end soon, otherwise it will be delayed until 11 o'clock, and lunch will have to go to the family to buy a rice ball to deal with it~EbookFREE.me~ The group will start.
　　 In Teacher Wei's office, everyone sat in a row and reported in turn.
　　 Wu Feifei: "This week, based on the lead thiocyanate system, I did XRD, DSC and other characterization..."
　　 Wei Xingsi: "Okay, who will talk next?"
　　 Duan Yun: "……"
　　 Wei Xingsi: "Okay, next one."
　　 In the last few group meetings, the atmosphere has always been sunny, and Teacher Wei has also changed a lot of Buddhism.
　　 The reason is also very simple. Xu Qiu and Chen Wanqing's article BUFF are still there. Wu Feifei and Tian Qing have worked very well recently, and Duan Yun's installation has also been successfully built.
　　 I just don’t know when this sunny day will turn from cloudy to sunny.
　　 Maybe, Teacher Wei has a steelyard in his heart.
　　 When should the pressure be given and when should be relaxed, in order to maximize the potential of students.
　　 In addition, with the increase in the number of participations, Xu Qiu has become accustomed to the form of group meetings, and is no longer as rigid as it was at the beginning.
　　 He also somewhat understood why Chen Wanqing was reluctant to participate in the group meeting.
　　 Because in the group meeting, the pressure of the poor progress of the experiment will be amplified with the criticism of Teacher Wei, and it will be transformed into worry about whether it can produce results and graduate successfully.
　　 Of course, Xu Qiu didn't realize this pressure, so he could only guess roughly, but couldn't empathize.

The 　　 group meeting ended relatively early. Xu Qiu and the fellows in the research group hurried to the entrance of the Fangda Gymnasium in the Southern District after having lunch together.
　　 The time is more than 11:40 minutes, and the bus reserved in the department has stopped in the parking lot next to it.
　　 Some time ago, the talented squad leader, who was newly elected at the class meeting, stood at the entrance of the gymnasium and was responsible for signing in and guiding the students to ride.
