Chapter 126: Mystery call

　　 Xu Qiu has in his mind all the experimental data based on the PBFBT4T-2OD system in the past two months.
　　 To write an article is to tell a story. The beginning of the story is probably like this:
　　 They synthesized a series of materials based on PBFBT4T. Through side chain engineering, the solubility and photoelectric properties of the materials can be adjusted. Among them, the best system is PBFBT4T-2OD.
　　 However, this part is regarded as a prequel, and another article can be published. He does not intend to include it in the main text this time.
　　 This time he intends to submit the work to the top magazine AM of the material sciences. He intends to cut directly into the topic, that is:
　　 Xu Qiu and other researchers have developed an efficient polymer donor material, PBFBT4T-2OD.
　　 A variety of characterization methods can prove that this donor material has high crystalline properties. Using spin coating methods, it can form a face-on molecular stacking structure suitable for organic solar cells.
　　Further, by controlling the temperature conditions during spin coating, the microscopic morphology of the blended film can be finely controlled.
　　Finally, the performance of the optimal solar cell device can reach more than 10%, and no solvent additives, thermal annealing and other post-processing methods are required.
　　 "Tick, tick..."
　　 Suddenly, a cell phone ringtone came, interrupting Xu Qiu's thoughts, and he recovered.
　　 If I remember correctly, the ringtone that comes with this rice phone should be Chen Wanqing.
　　 "Ah, it's Teacher Wei's call. It is probably asking about our experiment." Chen Wanqing said in a panic.
　　 "Take it, anyway, today's experiment is still going well, just report truthfully." Xu Qiu said.
　　 She took a deep breath and exhaled it slowly.
　　 was waiting to press the answer button, but found that the phone ringing stopped.
　　 called back and was quickly connected, she turned on the speakerphone.
　　 "Hey, Teacher Wei, I was testing just now and I didn't hear the phone ring."
　　 "Well, how is the measurement?"
"Okay……"
　　 "Senior sister, let me come." Xu Qiu whispered.
　　 He probably guessed what Teacher Wei wanted to ask, so he took the call from the senior sister.
　　 "Ms. Wei, this is Xu Qiu."
"what's the result?"
　　"In the morning, I mainly debugged the equipment. It took more than an hour, and then I tested a few samples. All of them are my system. From the raw data, the signal is more obvious.
　　 I just processed the data of the P2FBT4T-2OD individual components and blended films, and they all show a face-on molecular stacking structure.
　　 This result can be mutually confirmed with the previous DSC and TEM data, and then explain the reason for the high performance of the device. "
　　 "Okay, okay, then you can continue the test." Teacher Wei breathed a sigh of relief and asked:
　　 "By the way, how much is the meal and the fare, and who pays?"
　　 "I paid 60 yuan for lunch and dinner, and more than 60 taxi rides. I paid for it."
　　 "Okay, I will transfer the money to you later."
　　 After speaking, Teacher Wei hung up the phone and Xu Qiu returned the phone to the senior sister.
　　 Chen Wanqing gave him an OK gesture.
　　 "Ms. Wei will still check posts." Han Jiaying said.
　　 "Occasionally," Chen Wanqing said:
　　"If he often does experiments on the Handan campus, he will not call to ask.
　　 But if he stays at the Zhangjiang campus for a long time to do experiments and never comes back, he can't see people, and the experimental data reported by the group meeting is not ideal, he will call to find someone.
　　 Moreover, he is quite a chicken thief, Duan Yun was caught by him once before.
　　 Duan Yun was lazy in the bedroom that day. Teacher Wei called him and Duan Yun said that he was doing experiments in Zhangjiang.
　　 Finally, Teacher Wei asked him to use the landline of Zhang Jiang's A501 office to call back, and he was dumbfounded on the spot. "
　　 "Brother Duan Yun is so miserable."
　　 "Yes, I feel that he has helped me attract a large wave of Teacher Wei's attention, and I am much more relaxed now." Chen Wanqing said:
　　 "However, Mr. Wei is not like Cha Gang this time. He should be more concerned about the results of the experiment. After all, the younger brother is going to post a big article."
　　 "Sister, you laughed," Xu Qiu said modestly:
　　 "Let's continue the experiment. Today's time is tight. If you are tired, Han Jiaying, just tell us. There are three people today and you can take turns."
　　 "Okay." Han Jiaying nodded.
　　 Xu Qiu continued to process the experimental data.
　　 Not long after, he felt the phone vibrate.
　　 Turned on the phone and saw that it was Teacher Wei who transferred 200 yuan to him through ZFB.
　　 This time I spent 130, but I gave 200. Teacher Wei is still quite generous.
　　 Of course, it may also be that he misunderstood, and it became 60 yuan each for two meals.
　　……
　　 A little over two o'clock in the afternoon, a teacher came over to inspect at the station, not the last teacher Luo Yang.
　　 He seems to be in his 40s or 50s. It may be what Meng Ren said before, another teacher on duty.
　　 He saw the test here and everything was working well, and after a few words of advice, he left.
The test after 　　 was fairly smooth, only some samples needed to be placed at different angles, and most samples were completed in one go.
　　Xu Qiu's several systems, the signal is relatively obvious, even in the unprocessed grayscale image, you can see the crystal signal.
　　 After testing more than 30 samples, Han Jiaying and Chen Wanqing exchanged division of labor.
　　 The school girl operates the test software, and the school girl is responsible for replacing the samples.
　　 Xu Qiu is responsible for teaching, including software operation and subsequent data processing. UU reading www.uukanshu.cOM
　　 Time passed slowly, and the test process was rather boring. It was not that hard to rotate three people, and occasionally I would chat.
　　 After dinner, continue to test, Xu Qiu's turn to change samples.
　　 At about eight o'clock, a group of people walked outside the BL14B1 line station. They were like test users from other places.
　　 However, there are a lot of them, four men and three women, a total of seven people.
　　 Someone who looked like the leader took the initiative and said:
　　 "We are the ones to test next, are you almost finished testing."
　　 Chen Wanqing became a diplomatic envoy:
　　 "There are a few more samples. The test will definitely be finished before nine o'clock. Where did you come from."
　　 "We are from Shanda, how about you?"
　　 "Shandong University, come here so far? We are from Magic University."
　　 "The local university in the magic city, envy, we all came here as a high-speed rail, and we have to stay here for one night."
　　 After a few polite greetings between the two, he led the group of seven to the nearby lounge, and did not disturb Xu Qiu and the others.
　　 Continue the test, at 8:40, all samples, including blank silicon wafers and lanthanum hexaboride have been tested.
　　 Meng Ren appeared again, he should have come to change shifts.
　　 After Xu Qiu and the three people signed the registration form, they left Magic City Light Source and took a taxi back to school.
　　……
　　 Chen Wanqing returned to Caiyi. She had to sit in the office for a while, and could not get off work until ten o'clock.
　　 Xu Qiuze and Han Jiaying returned to the bedroom together.
　　 The bathroom was closed, and Xu Qiu had to take a shower in the corridor.
After 　　 came back from the shower, he found a missed call on the phone.
　　 glanced at the caller's note, he picked up the phone and walked out the door.
