Chapter 76: The second group meeting

　　 Monday morning.
　　 Xu Qiu returned to the bedroom after eating early, ready to take another look at the PPT for the group meeting that he did yesterday.
　　 But when he turned on the computer, he was confused and the files on the desktop disappeared.
　　 Could it be deleted by mistake?
　　 Did I make a PPT in a dream?
　　 Wait, it seems that I did it in a dream.
　　 Xu Qiu entered the simulation laboratory and turned on the computer.
　　 As expected, the PPT file was lying quietly on the desktop of this computer.
　　The question is, how should I take out the files inside?
　　 "System, can I take this computer out?"
　　【No. 】
　　 It seems the same as before, all the physical objects that enter the simulation laboratory cannot be taken out.
　　 Xu Qiu changed his questioning method:
　　 "System, can you take out the data in this computer?"
　　【Yes. Currently, a two-way data transmission node can be established. Should the node be set on the host's laptop? 】
　　 "Set it up."
　　【The setting is successful, the host can realize data transmission through the shared folder function. 】
　　 Xu Qiu saw an extra shared folder on the laptop desktop in front of him.
　　He dragged the PPT file of the group meeting into it, and then left the simulation laboratory.
　　 A shared folder also appeared on the real computer desktop.
　　 He tried to drag and copy the file to the desktop.
　　 The progress bar only flashed once, and the copy was successful, and the data transmission speed was very fast.
　　 Open the file for verification, and it turned out to be the PPT made in the simulation laboratory yesterday.
　　 Xu Qiu started brainstorming:
　　 This function looks very powerful, what's the practical effect?
　　 Take an extra hard drive with you?
　　 Or, save some private files?
　　 It seems that there is no other use.

　　 laboratory.
　　 There was a group meeting on Monday morning, and everyone came earlier.
　　 Tian Qing also came here, she just came back from the neon country the day before yesterday, and it seems that she is having fun going abroad.
　　 She brought souvenirs to the little friends in the laboratory. They were all snacks, including white lover biscuits, waffle sticks and so on.
　　 The laboratory was full of laughter, but it didn't take long for everyone to be summoned to 218 by Teacher Wei.
　　 When passing through Room 219, Xu Qiu did not forget to summon the system and copied a server into the simulation laboratory.
　　 However, there is no chance to test its performance right now.
　　 218 room.
　　 Teacher Wei first named Tian Qing.
　　 "Did you have fun in summer vacation?"
　　 "I'm quite happy."
　　 "School is starting, so I have to do some experiments."
"Ok."
　　 "Is there anything to share with us."
　　 "Yes." Tian Qing said excitedly.
　　 She opened the PPT and started speaking.
　　 This is a documentary explanation about MIS-CELIV technology.
　　 Xu Qiu listened carefully for a while, but didn't quite understand it. He only knew that it was an improvement based on the traditional CELIV, involving a lot of theory and calculations.
　　 His gaze floated towards Teacher Wei. Judging by his look, he guessed that Mr. Wei didn't understand him very much. Later, Mr. Wei began to lower his head to operate his computer.
　　 Twenty minutes later, Tian Qing finally ended.
　　 Teacher Wei raised his head and said blankly:
　　 "Good point, who is next, Feifei Wu."
　　 Wu Feifei began to introduce her work. Her ammonium chloride additive system can achieve almost the same efficiency as the standard sample.
　　 It seems that a problem with the circulating water system during the weekend did not affect her experiment.
　　 Then it was Duan Yun. He went to the Zhangjiang campus to do synthesis last week, and prepared quaternary copper-based sulfides doped with different copper content, and planned to go to the Zhou Dagang research group of Tongji University for testing this week.
　　 It's no wonder that I didn't see Duan Yun a few days ago. I met again today, and my tanned complexion seems to have recovered a lot.
　　 followed by the senior sister, she said that she was mainly writing articles this week, and also showed her synthesis plan:
　　"Synthesis of ternary conjugated copolymer based on BDT-TT-BT and BDT-BT-DPP."
　　 Teacher Wei smiled after seeing it, "You plan to do this."
　　 Then he said: "It's not impossible, so what are the advantages of your two systems?"
　　 "If it is good, the binary D-A system has the disadvantage that the various properties of the molecule cannot be controlled," Chen Wanqing seemed to be prepared and talked freely:
　　 "After the introduction of the third unit, its performance can be flexibly adjusted, such as solubility, light absorption performance, energy level structure, molecular stacking structure, blending performance with receptors, etc."
　　 "Okay, as long as you can tell a story, just do it and see." Wei Xingsi immediately looked at Xu Qiu and said:
　　 "Xu Qiu, is this your synthesis plan together?"
　　 "I also have my own plan." Xu Qiuyang raised the USB flash drive in his hand and inserted it into the big computer.
　　 "First of all, I will introduce the experimental work of last week, repeated experiments, the highest efficiency of FAPbCl3 positive structure device reached 10.52%, but it is estimated that 11% will not be reached."
　　 "Forget it if you can't go up, have you done it in reverse?" Wei Xing thought.
　　 "Inverted structure is not good, the highest efficiency is only 8%."
　　 Teacher Wei nodded and signaled Xu Qiu to continue.
　　 "This is a stability test. I have been doing it for a week, and the efficiency can still be stable above 10%.
　　 "This data is good, you can continue to do it first, and then add the latest data until you are ready to submit." Teacher Wei said.
　　 Xu Qiu switched to the synthetic route page ~EbookFREE.me~ and said, "This is the molecular synthetic route I designed."
　　 He stuffed several pictures in a PPT, so the pictures displayed are relatively small.
　　 "The picture will be bigger in the future." Teacher Wei stood up, walked to the white curtain to check carefully, and said:
　　 "Your molecular structure looks very new. Have you done DFT simulation?"
　　 Xu Qiu made only one of the DFTs on Wei’s big computer, and the others were advanced DFTs made in the simulation laboratory, and said:
　　 "Only made one, BT-2T structure, mainly to look at the dihedral angle, the result shows that the dihedral angle between the BT and T unit is close to zero, indicating that the coplanarity is good."
　　 "Well, these two structural units are relatively small. If the side chain is not large, the coplanarity will be good." Teacher Wei said:
　　 "And according to my previous synthesis experience, the general performance of this conjugated system of five-membered and six-membered rings is also good."
　　 Chen Wanqing seemed to be in a good mood when seeing Teacher Wei, and interjected:
　　 "Mr. Wei, you need to buy monomers for synthesis. How much do you think we can buy?"
　　 "What is the approximate price of a single unit?" Teacher Wei's smile quickly faded when he heard the request for money.
　　 "The cheap one is a few hundred to one thousand yuan per gram, if it is more expensive, two to three thousand one gram." Chen Wanqing said.
　　 "Then how much budget do you think is appropriate."
　　 "Two..." Chen Wanqing hesitated and said:
　　 "Ten thousand?"
　　 "Five thousand," Wei Xingsi finalized the budget:
　　"Don’t spend it all at once, buy less of each monomer first.
　　 It is also the same for synthesis reactions. First put one or two hundred milligrams of raw materials to test the water, and make a large batch after exploring the conditions. "
