英国伦敦学院大学Gopinathan Sankar教授9月9日下午在化院二楼报告厅为我室师生作了题为“Application of X-ray techniques for the study of nano structured materials”的学术报告,得到在场的师生阵阵好评,整个报告过程中掌声不断。
Gopinathan Sankar教授是英国伦敦学院大学化学系的教授。他在加入伦敦学院大学前曾在英国皇家科学院和印度科学研究所任职。他曾发表225多篇研究成果,目前的H指数是47。他接受邀请在国家和国际会议上做学术报告,并且在世界各地许多大学和研究机构做邀请报告。他的研究领域包括多相催化,纳米结构材料,结构和材料反应活性,这些材料包括沸石型纳米多孔材料和金属纳米粒子,并在同步辐射的X射线技术方面有一定深入研究。他2007年和Johnson Matthe一起获得英国皇家社会产业奖励。Gopinathan Sankar教授目前继续与Johnson Matthe教授一起在多个方面开展合作。
本次学术报告的主要内容如下:
Several nano structured materials are produced using solution processing methods which includes nano metals, oxides and porous materials such as zeolites, aluminophosphates and metal-organic frameworks. While these materials are widely used for a range of applications, it is important to understand the growth processes of these materials and structure at various stages. To understand the reactivity under dynamic conditions, it is necessary to employ techniques that provide sufficient time resolution to determine the structure under operating conditions. X-ray techniques in particular using Synchrotron Radiation offers many such possibilities. A detailed discussion of how the combination of X-ray techniques provide detailed information of size, shape, short, medium and long range structures of nano structured materials by taking examples from metal nano particles and crystalline zeolite systems. Advantages and disadvantages of these techniques will be discussed in detail.
