Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

In the present chapter, brief history, working principle, instrumentation and, recent applications of Scanning Electron Microscopy (SEM) have been enlightened. SEM is a highly sensitive and efficient magnification tool that exploits focused beams of electrons to obtain information allied to topography, morphology, and composition of materials. Utilization of SEM techniques in different fields, like various domains of materials science, forensic investigation, mechanical engineering, biological, and medical sciences has been discussed.
