 Hello everyone, I am Dr. S. Shankaran, a faculty member in the Department of Metallurgical and Materials Engineering IIT Madras. I will be offering the online course on fundamentals of optical and scanning electron microscopy. It is a first course at the undergraduate level on the microstructural characterization of materials. The course will cover the principles and techniques of optical and scanning electron microscopy with demonstrations of instrumentation details and experiments through videos. This course also will cover the sample preparations for optical and scanning electron microscopy and also we will deal with practical examples. This course will be useful if you are pursuing an undergraduate program in basic science or engineering who deals with material characterization or microstructural details or topology of materials in nature. Thank you.
