Research Profile

Liu Wei, male, born in December 1956, currently works as a professor and doctoral supervisor at the Department of Materials Science and Technology, University of Science and Technology of China (USTC). Liu obtained his B.S. in Physics from Northwest University (Sha’anxi) in 1982, and his M.S. in Structural Chemistry and Ph.D. in Condensed Matter Physics from University of Science and Technology of China in 1988 and 1991 respectively. After the completion of his Ph.D. studies, Liu joined the faculty of USTC and worked at the Key Laboratory of Internal Friction and Defects in Solids, Chinese Academy of Sciences. Liu got promoted to lectureship in December 1991, and then became a research associate in October 1993. In January 2001, Liu was promoted to the position of a research professor. From 1997 to 2001, Liu assumed the post of Deputy Director of the Key Laboratory of Internal Friction and Defects in Solids and Member of the Academic Committee of the lab. Liu also went to the University of Twente in the Netherlands in 2002 as a senor visiting scholar on academic exchange missions.
     Liu had been engaged in research on mechanical spectra of materials, preparation and characterization of thin films, as well as defects and transport properties of solids. In recent years, Prof. Liu has been mainly committed to scientific research on solid-state ionic materials as well as moderate and high temperature inorganic membrane materials and technologies widely used in fields of energy and environment. Prof. Liu has presided over two surface projects supported by the National Natural Science Foundation of China, one being “Research and Preparation of Oxide Membrane in Low-Temperature Mixed Conductors” and the other being “Anelasticity Study of Additional Interstitial Oxygen in K2NiF4 Structures”, one exploration project of “Tubular Ceramic Membrane Fuel Cell Preparation Technology” in the field of advanced energy sources supported by the National High Technology Research and Development Program of China (namely, the “863” Program), as well as some other open projects supported by the Knowledge Innovation Program of the Chinese Academy of Sciences. In his capacity as a major participant, Prof. Liu also undertook two research projects supported by the National High Technology Research and Development Program for New Materials of China (namely, the “863” Program), one being “Research on Inorganic Membrane and Catalytic Materials” and the other “Research on Moderate and High-Temperature Ion-conducting Membranes Materials in Clean Energies”. Prof. Liu boasts rich research experience and has made important progress in his research in the field of the preparation, processing, structure, and transport properties of inorganic materials (mixed ionic conductors in particular) as well as their intrinsic relationship. Up to now, Prof. Liu has authored more than 100 research papers published in academic journals both at home and abroad, and two patents.
