【Biography】

Shulong Wen, Ph.D. I am mainly engaged in the first principles research of Oxide / Carbide material diffusion reinforced tungsten-based alloys (ODS-W) and the catalytic characteristics of material surfaces. The host projects include the National Natural Science Foundation of China and the university talent launch project. More than 10 articles were published in the Nuclear Fusion journals and Journal of alloys and compounds. Currently, I am a full-time teacher of College of Communication Engineering (College of Microelectronics), Chengdu University of Information Technology.
