Prof. X. Yao, from Shanghai Jiao Tong Univ., got his Bachelor and Master degrees in Dept. Mater. Sci. and Eng., of Shanghai Jiao Tong Univ., and got his Ph.D. at Univ. of Liverpool, in. 1993. He was a research scientist at ISTEC（International Superconductivity Technology Center） in Japan (1993-2001). During work at ISTEC, he has grown the world record, large-sized REBCO single crystals. In his new lab at Shanghai Jiao Tong Univ (from 2002), he has extended the growth of REBCO crystals to the bulks and LPE films, focusing his interests on the phase formation and the growth mode in various RE-Ba-Cu-O systems.
