【學(xué)術(shù)報告】關(guān)于研究生靈犀學(xué)術(shù)殿堂第125期之Prof.Mike Reece報告會的通知
全校師生:
我校定于2017年3月31日和4月1日舉辦研究生靈犀學(xué)術(shù)殿堂——Prof.Mike Reece報告會,現(xiàn)將有關(guān)事項通知如下:
1.報告會簡介
報告人:Prof.Mike Reece
(1)報告會一:
時 間:2017年3月31日(星期五) 上午09:30(開始時間)
地 點: 友誼校區(qū) 公字樓328
主 題: Densification and Microstructural Engineering of Ceramics using Electric Current Assisted Sintering
內(nèi)容簡介: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)報告會二:
時 間:2017年4月1日(星期六) 上午09:30(開始時間)
地 點: 友誼校區(qū) 公字樓328
主 題: Thermoelectric Properties of Cu-Sb-S Compounds
內(nèi)容簡介: 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).
