| Abstract: | The synthesis and applications of nanomaterials have seen great progress in recent years.However,with the limitation of effective characterization techniques,our understanding of many key issues in nanotechnology is still restricted.Synchrotron radiation based techniques provide many advantages in nanomaterial charaterization due to their energy tunability,high brightness,polarization,time structure,coherence,and so forth.With the development of the third generation of synchrotron radiation facilities in China,these techniques will offer unique opportunities to investigate nanomaterials and obtain real time,in_situ and dynamic information.Here we will describe recent developments of some new synchrotron radiation-based techniques for nanomaterial studies,illustrated by various examples. |
