Color center and radiation center in Lu2SiO5:Ce crystal秦来顺1,2,陆晟2,丁栋舟2,李焕英2,任国浩21. College of Materials Science and Engineering, China Jiliang University2. Shanghai Institute of Ceramics, Chinese Academy of Sciences摘 要:Radiation damage of Lu2SiO5:Ce (LSO:Ce) crystals was investigated through intense UV light. An absorption band at 435 nm was observed......
objective of present investigation is to introduce the novel aspects of convective mass condition and thermal radiation in the peristaltic transport of fluid. Magnetohydrodynamic (MHD) fluid was considered in a symmetric channel. Heat and mass transfer characteristics were analyzed in the presence of Soret and Dufour effects, and the results were presented via two forms of thermal radiation......
