Academic report: Prof. Huang Jianbin and Prof. Liu Huan


 On October 14, 2019, Professor Huang Jianbin of Peking University and Professor Liu Huan of Beijing University of Aeronautics and Astronautics visited our university at the invitation of Professor Feng Shi of  the State Key Laboratory of Chemical Resource Engineering, and respectively made wonderful academic reports entitled regulation and control of amphiphilic ordered groups in solution and fiber induced liquid controllable transportation.

     In the report of regulation of amphiphilic ordered compounds in solution, Professor Huang Jianbin proposed that amphiphilic ordered structures have important significance for the development of related disciplines, such as membrane simulation function in the field of life science, catalytic function in the field of core chemistry, entrapment and permeability function in the field of medical pharmacology and template function in the field of material science. Mr. Huang focused on the following aspects: (1) the progress of current work: the research of ordered groups in the system of positive and negative ion surfactants, the characteristics and rules of the formation of ordered structures in new surfactant solutions, the influence of environmental factors (2) temperature induced micelle vesicle transition (3) pH controlled molecular self-assembly behavior (4) additives, surfactants, a **all amount of The regulatory effect of cyclodextrin on ordered compounds.

       In the report of fiber-induced controlled liquid transport, Professor Liu Huan first revealed that the physical and chemical mechani** of controlled and efficient transport of low viscosity liquid by Chinese brush is the limited dynamic equilibrium of liquid under the action of multiple driving forces induced by multi-scale asymmetric microstructure of newborn hair. This paper mainly introduces the following three aspects: (1) using dynamic balance, fiber can realize the controllable transportation of liquid. Through the construction of radial fiber array, it is revealed that the elastic potential energy of fiber is an important driving force for controllable and efficient transportation of liquid, and the theoretical model of fiber transportation of liquid is further established. (2) a new method of patterned surface using fiber controllable transport functional liquid has been developed to realize the controllable transport of various functional molecules and nano materials at the micro nano scale. (3) based on the super wettability of asymmetric fibers, a novel template free direct printing method is proposed to prepare patterned organic nano films.

      At the end of the report, all the teachers and students who participated in the report spoke enthusiastically and asked questions. They discussed and exchanged with Professor Huang Jianbin and Professor Liu Huan in different directions.

       Huang Jianbin, Professor of Peking University. He entered Peking University in 1983. In 1987, 1990 and 1993, he obtained bachelor's degree, master's degree and doctor's degree respectively in the Department of chemistry, Peking University. From 1993 to 1995, the Institute of physical chemistry of Peking University carried out postdoctoral research. In 1995, he stayed at school. He is now a professor and doctoral supervisor of Peking University. A member of the Royal Society of chemistry. Director of China colloid and Interface Chemistry Committee. Deputy editor of soft matter, lamgmuir and JCIS. In 2016, he won the China soft material outstanding contribution award / in 2001 and 2005, he won the China outstanding postdoctoral award. In 1998, 2011, he won the research excellence award of Peking University for three times. In 2003, he won the Teaching Excellence Award of Peking University. In 2004, he was supported by the National Science Foundation for Distinguished Young Scholars. In 2005, the team of physical chemistry won the first prize of teaching achievement of Peking University. In that year, he also won the first prize of excellent teaching team of Peking University as a key person.
        Liu Huan, professor and doctoral supervisor, School of chemistry, Beijing University of Aeronautics and Astronautics. In 2016, he was supported by the National Excellent Youth Fund, the new century talent support plan of the Ministry of education in 2013, the Huo Yingdong Youth Education Fund in 2012, and the special award of the president of the Chinese Academy of Sciences in 2004. In 2005, he graduated from the Institute of chemistry, Chinese Academy of Sciences, with a doctor's degree, and studied with Academician Jiang Lei. Later, he joined the National Center for nanoscience, and in 2007, he joined the research group of Professor Hirohito Hashimoto (now president of the National Institute of materials) of Tokyo University in Japan to engage in postdoctoral research. In May 2011, he was selected into the excellent 100 Talents Program of Beijing University of Aeronautics and Astronautics and joined the school of Beihang chemistry full time. He has been engaged in the research of dynamic behavior and physicochemical mechani** of fiber regulating liquid for a long time, including the physicochemical mechani** of dynamic wettability of fiber, controllable transport and patterning of liquid, self-assembly of nano materials and integrated devices. He has published 70 SCI papers in NAT. Commun., J. am. Chem. SOC., angelw. Chem. Int. ed., adv. mater., ACS Nano, and cited more than 2600 times.
