Overview
Microscopic methods play an essential role in nanomaterials characterization. Microscopic and X-ray based characterization of nanomaterials techniques are used for the determination of surface morphology and dispersion characteristics of nanomaterials. This course deals with details of these aspects, and will provide a fundamental understanding of morphological tools, such as instrumentation, sample preparation and different kinds of analyses, etc.
