Chapter 9: The other side of senior sister

　　 In the afternoon, the laboratory.
　　 "Sister, besides you, what about the other brothers and sisters in the laboratory, why haven't I met before?" Xu Qiu asked.
　　 "Oh, there is also a brother Duan Yun of Boyi and Feifei Wu, a senior sister of Yanji. They are basically on the Zhangjiang campus recently." Chen Wanqing said:
"The area of ​​the laboratory here is too small. Teacher Wei and the department applied for a new laboratory, and the department agreed, but there were no free laboratories on the Handan campus, so the new laboratory was assigned to Zhang Jiang. Campus.
　　 The Zhang Jiang laboratory is currently under renovation and needs someone to watch it. It just so happened that both of them were writing reviews recently and there was no need to do experiments, so Teacher Wei sent them two to supervise the work. "
　　 Xu Qiu gossiping: "Brother and sister, are they..."
　　 Chen Wanqing rolled her eyes: "You think too much."
　　 "Then when will they come back here?" Xu Qiu said:
　　 "I haven't seen them."
　　 "It's Sunday, everyone is basically in the laboratory of Handan campus." Chen Wanqing said:
　　" Zhang Jiang's laboratory will be ready before summer vacation, and you will be able to see them often.
　　 By the way, there is also Tian Qing, a senior graduate student in our school. She is preparing for graduation defense in recent days, so she has no time to come to the laboratory to do experiments. "
　　 "I know, Teacher Wei mentioned her to me." Xu Qiu said.
"I heard that there was originally a senior here. When he was a junior, he applied for a school scientific research project on Teacher Wei's side. As a result, he went to Bay Province to exchange for half a year after the project was launched. The research team is finished. This is what I heard from Wu Feifei." Chen Wanqing said.
　　 "So what's the reaction of Teacher Wei?" Xu Qiu said.
　　 "It is said that he was very angry at the time, but it was of no use. He couldn't control the undergraduates, and in the end, he just lost it." Chen Wanqing said.
　　……
　　 After chatting for a while, Xu Qiu took out the literature from the bag.
　　 "I have read the literature, are there any gains?" Chen Wanqing said.
　　 "I went to MedSci to check the journal information first, and then I mainly read the abstract, the conclusion part and the introduction part of this "Chemical Review". The text has not been read yet." Xu Qiu said:
　　 "I feel that the summary and conclusions are not very helpful to me, the introduction is more useful, and the introduction is more detailed. I use a notebook to record all the core points."
　　 "Generally, novices read the literature like reading a book from scratch. Who taught you how to read the literature?" Chen Wanqing said.
　　 "The department has a course called "Document Retrieval". When I helped the teacher download the documents, I tried to read a few articles and then figured it out by myself." Xu Qiu said.
　　 "Teach yourself without a teacher, it's amazing." Chen Wanqing exclaimed.
　　 "I don't dare to be, but I have to ask my senior sister for advice." Xu Qiu smiled.
　　 After that, he handed the notebook to Chen Wanqing.
　　 "It's a good summary, are the areas marked by the highlighter that you don't understand?" Chen Wanqing asked after flipping through it.
　　 "Yes." Xu Qiu said.
　　…………
　　 After communicating with the senior sister, he found that the senior sister was very knowledgeable about the field of organic photovoltaics, and he answered many of his doubts.
　　 This is nothing like that cute elder sister yesterday.
　　 But think about it, most people who can get a Ph.D. at Mordu Comprehensive University still have two brushes.
　　 It is said that the probability of postponing the graduation of a PhD in the Department of Materials is more than 30%.
　　 Many people are reading, and they have changed from Ph.D. to Ph.D.
　　 Then, he proposed to his senior sister to teach him literature reading skills, and Chen Wan readily agreed.
　　 [The reading skill of the literature is detected, whether to record it? 】
　　 "Record."
　　 Xu Qiu glanced at the system interface:
　　【Scientific Research Support System】
　　……
　　【Special category】
　　 Literature reading (first order 57% / fourth order 50%)
　　##
　　 As expected, it is Tier 4, not bad.
　　 In the first few steps, there is little difference between the reading method and the system of the literature.
　　 just she added some details, such as:
　　" The title of the paper is very important to the author, because when the journal editor gets the manuscript, if he sees the title is too bad, he may reject the manuscript without reading the main text.
　　 Therefore, when reading the title, pay attention to how others start the title, especially the key words and sentence structure.
　　 My master's supervisor would sit in the office for an afternoon before submitting an article, picking a good title to increase the probability of submission for review. "
　　……
　　 When it comes to the text, Xu Qiu pricked his ears and listened carefully.
　　"The main text contains a complete argumentation process, which is usually very long, so it is necessary to focus on it.
　　 First look at the pictures and subtitles. Of course, there is usually no subtitles, but this has little effect. The subtitles only play an auxiliary function. The main thing is to look at the pictures. Most of the core arguments will be displayed in the pictures. "
　　 "Then, for example," Chen Wanqing randomly pulled out a document from the nearby document cabinet and said:
"Look at the title first to determine the general content of the article. This article is "Design, Synthesis and Photovoltaic Application of a New Type of Narrow Band Gap Polymer Donor Material". UU reading www.uukahnshu.com can judge that the core of the article is this New donor material.
　　 Next, you can read the summary, conclusion, and preface in the same way as I said before, and if you like me, you will turn to the picture directly.
　　 Picture one is the synthesis route of this new type of donor material called DPP3T, there is nothing to say about it;
　　 Figure 2 shows its electrochemical performance. It can be seen that it matches the energy level of the acceptor material, which is conducive to charge transport;
　　 Figure 3 is its optical performance, you will find that it has very good light absorption performance in the visible light range;
　　 Figure 4 is to mix it with the acceptor material and coat it, and then take a transmission electron microscope, it can be found that the mixing is relatively uniform and has a better blending morphology;
　　 Figure 5 is the core characterization method of solar cells. The voltage-current density curve shows that the photoelectric conversion efficiency of the device based on it can reach 8%.
Then connect these five sentences, that is, we have synthesized a new type of donor material called DPP3T, which matches the energy level of the acceptor material and is conducive to charge transport; it has good light absorption performance in the visible light range; It can form a better blend morphology after being mixed with the receptor. We have prepared organic solar cell devices based on it, with an efficiency of 8%. "
　　 Finally, the senior sister was full of confidence: "Although I haven't read the other parts of this article, I know that its story must be said like this."
　　 Xu Qiu took the literature, looked at the abstract, and found that it was exactly the same as the senior sister said, and couldn't help sighing:
　　 "I, senior sister is amazing!"
　　…………
　　Parting.
　　 "Speaking of senior sister, why didn't you teach me when you gave me documents before."
　　 "I, I'm not going to test you."
　　 "Really?"
　　 "Really."
