Description Microscopic characterization methods refer to scientific techniques Which allow determination of both composition and structure of a material. Optical microscopy, scanning probe microscopy and electron microscopy are known as microscopic techniques. This course illustrates how microscopic characterization techniques are used.
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.


Booklet
Description
In this lesson different phases of crystal structure have been investigated. The XRD pattern of a material can be obtained from a single phase material or multi-phase material. The crystallite size can be calculated using X-ray diffraction.

Mental Challenge

Which relation is useful for calculatingthe crystallite size? 



Quizzes and Activities
Activity: Compare the different XRD diffraction patterns of SiO2.
