全校师生:
云顶集团定于2017年3月31日和4月1日举办研究生灵犀学术殿堂——Prof.Mike Reece报告会,现将有关事项通知如下:
1.报告会简介
报告人:Prof.Mike Reece
(1)报告会一:
时 间:2017年3月31日(星期五) 上午09:30(开始时间)
地 点: 友谊校区 公字楼328
主 题: Densification and Microstructural Engineering of Ceramics using Electric Current Assisted Sintering
内容简介:The talk will review the use of Electric Current Assisted Sintering (ECAS) techniques, such as the commonly referred to Spark Plasma Sintering (SPS), for the processing of materials. This includes the potential advantages and disadvantages of the technique. SPS has been widely applied because of its ability to produce nanostructured materials. However, the techniques has other potential advantages, such as the ability to produce non-equilibrium structures. Recent results on the flash sintering (heating rates of > 10,000°C/min) of ultra-high temperature ceramics, and thermoelectrics will be presented. The application of ECAS to functional materials brings additional effects, including the Peltier/Thomson effects. These effects can bring advantages and disadvantages and need to be understood in order to optimise the engineering of the microstructures of materials. Experimental and modelling results will presented to quantify the magnitude these effects.
(2)报告会二:
时 间:2017年4月1日(星期六) 上午09:30(开始时间)
地 点: 友谊校区 公字楼328
主 题: Thermoelectric Properties of Cu-Sb-S Compounds
内容简介: The discovery and design of compounds with intrinsically low thermal conductivity, especially compounds with a special bonding nature and stable crystal structure, is a new direction to broaden the scope of potential thermoelectric (TE) materials. This study was motivated the earth-abundant sulfide tetrahedrite (Cu12Sb4S13), which has intrinsically low thermal conductivity due to the Sb lone-pair electrons and CuS3triangular planes . To further understand the effects of lone pair electrons of Sb and explore new potential thermoelectric sulfides, we report a comprehensive study of all four Cu-Sb-S compounds, including tetrahedrite (Cu12Sb4S13), famatinite (Cu3SbS4), skinnerite (Cu3SbS3) and chalcostibite (CuSbS2).
