应磁学与磁性材料教育部重点实验室（物理科学与技术学院）彭勇教授邀请，荷兰Delft大学徐强博士于4月9日（周三）下午3:00在齐云楼620 报告厅讲学，做客拉斯维加斯0567官方网站学术沙龙2014年第一场主题报告，敬请关注！

报告题目：Seeing is believing: observing kinetics at atomic level

报告时间：4月9日（周三）下午3:00

报告地点：校本部齐云楼620 报告厅

报告摘要：

In situ experimentation in transmission electron microscopes (TEMs) has always been an exciting field of study. Over the years, improving the resolution of a TEM has been driving the research and development in this area, however, now that we have reached sub-angstrom resolution, the application of transmission electron microscope as a tool to study dynamic changes in a specimen is one of the major areas where the future interest lies. These dynamic changes could be induced either by heating, applying a bias, or by creating a reactive environment inside the TEM.

Recently, with the advancements in microelectromechanical systems (MEMS) based technologies, the area of in situ TEM has progressed rapidly over the last decade.

Here, we show the results from a few applications of our MEMS based heating system to investigate commonly studied materials in situ. During the demonstration on TITAN, we will show either the heat treatment of aluminium alloys or core-shell nanoparticles.

报告会结束后，徐强博士将到物理科学与技术学院格致楼透射电镜室演示高分辨率透射电镜原位材料加热作用下结构、形貌实时动态变化过程研究，欢迎感兴趣的老师、同学参加！
