Talk Abstract

A series of lectures were held which dealt with Electron microscopy techniques. The various aspects of Transmission Electron microscopy, such as sample preparation, placement and focusing of the sample was discussed in detail. Principles of Raman Scattering, Rayliegh Scattering, Stokes and anti Stoke’s  scattering were discussed in depth. The talk also touched upon the basics of Raman Spectroscopy to observe vibration and low frequency modes.
