At the invitation of Professor Huang Hui, Professor Myung-Han Yoon of Gwangju Institute of Science and Technology, South Korea, gave an academic report on organic electronic devices in the afternoon of November 22, 2019 at 213, the first floor of the Yanqi Lake Campus.

      Organic electronic devices are widely used in our daily life and have become one of the research hotspots in recent years. Professor Myung-Han Yoon gave a brief introduction to the research background of organic electronic devices, expounded the latest research progress and existing problems in this field, and introduced his research work from two aspects. On the one hand, in view of the problems existing in the application of common organic electrolytes such as PMMA and PS in thin-film transistor applications, Professor Myung-Han Yoon proposed the idea of using sulfur-containing polymers as dielectric layers. The sulfur-containing polymer as a dielectric layer exhibits many excellent properties, greatly reducing the leakage current and operating voltage of the device. At the same time, due to the effect of S-S bonds, the device also has the ability of self-healing, which greatly improves the performance of thin film transistors. On the other hand, considering the excellent electrical properties, environmental stability and biocompatibility of PEDOT:PSS Features, Professor Myung-Han Yoon applied it to biosensors. Water-stable electrochemical transistors were fabricated using crystalline PEDOT:PSS films, and the devices exhibited excellent performance, expanding the application of this material in biosensing. Finally, teachers and classmates actively participated in the discussion and exchanged views, which benefited everyone a lot. The report ended successfully with the enthusiastic participation of everyone.

      In the afternoon of Nov. 5, Prof. Zhang Fujun from Beijing Jiaotong University was invited by Prof. Huang Hui from School of Materials to visit our university and gave a lecture entitled "Progress of organic photovoltaic and multiplying organic photodetection research" in the academic garden 2-318. The participants had a lively discussion with Prof. Zhang.

      Prof. Fujun Zhang has been engaged in the research of inorganic and organic electroluminescent devices, organic photovoltaic devices and organic photodetectors, especially he started the research of organic photovoltaic in ternary system earlier and reported the multiplicative narrow response organic photodetector for the first time in the international.

      From October 8th to October 12th, 2019, Mr. Huang Hui, Mr. Shi Qinqin and members of the research group Lv Lei, Wen Kaikai, Yang Haojie and Wenxuan participated in the one-week polymer annual meeting. Mr. Huang Hui made a Wonderful report, on-site teachers and classmates had a heated discussion, and made plans for the research direction of the research group!

      Conference Introduction: The National Polymer Academic Paper Series Report started in 1954. The biennial national report conference has become the most important academic conference in the domestic polymer science community and a grand event in the Chinese polymer community. The 2019 National Polymer Academic Papers Report was held in Xi'an from October 15 to 19, 2019, hosted by the Polymer Discipline Committee of the Chinese Chemical Society and undertaken by Northwestern Polytechnical University. This conference will focus on the important role of polymer science and technology in the national economy and society in the new era, and will focus on displaying the research achievements and development trends in the field of polymer science and materials in my country in recent years. , education, industry workers and young students to provide a broad academic and technical exchange platform to promote the sustainable development and innovation of my country's polymer disciplines, improve the level of cross-disciplinary and cutting-edge research in polymer-related disciplines, meet major national needs, and overcome core key technical problems, and promote the transformation of scientific research results.

      On the afternoon of August 20, Professor Yao Yan from the University of Houston, USA, was invited by Professor Huang Hui from the School of Materials Science and Technology to visit our school for an academic visit, and gave an academic report entitled "Application of Organic Electrodes in Lithium Batteries" at Xueyuan 2-302. Combined with his own research experience, he briefly described the urgency of current energy sources and the research progress of lithium batteries. Huang Hui's research group, Liu Xiangfeng's research group members and Professor Yao had a lively discussion.

      Yao Yan graduated from Fudan University, and then obtained his Ph.D. in Yang Yang's research group at UCLA. After two years of working in Polyera Corp., he entered Stanford to follow Professor Cui Yi to carry out research on electrochemical storage. Joined the University of Houston in 2012 to conduct independent research. His current research interests are the design of organic electrode materials and their applications in electromagnetism.
