Xie Sishen, physicist, has been engaged in the study of synthesis, structures, and physical properties of nanomaterials for decades. Xie graduated from the Department of Physics at Peking University, China, in 1965. He received his Ph.D. in 1983 from the Institute of Physics (IOP), Chinese Academy of Sciences. During 1984–1986, he worked as a post-doctoral research fellow at the Department of Electrical Engineering and Computer Science, Colorado University, USA. He is now a professor at IOP.Prof. Xie has conducted research in several fields of condensed matter physics, including phase diagrams, structures, and properties of rare earth alloys; synthesis, phase relationship, structural determination and properties of High Tc superconductors, and nanoscale materials, especially the carbon nanotube and other one-dimensional materials. He received the first prize of the National Natural Science Awards of China in 1989 for the discovery of High Tc superconductors at liquid nitrogen temperature, the third prize in 1991 for his research on the synthesis, phase relationship, and structure determination of High Tc superconductors, and the second prize for his work on aligned carbon nanotubes.
