Newer Avenues: Electron Microscope

NITR has never left a stone unturned when it comes to inspiring its students as well as faculty members to try out every possible scope of research, or experimentation they tap.

An electron microscope is a scientific instrument which uses a beam of electrons to examine objects on a very fine scale. In an optical microscope, the wavelength of light limits the maximum magnification that is possible. As electrons have a smaller wavelength, they can achieve a higher magnification, and can see very small objects - typically around 1,000 times smaller than those seen in an optical microscope. The outline of objects, as revealed by the flow of electrons, is changed into a picture using visible light for people to see.

Experiments based on this field are gaining popularity in recently and have a huge scope of research.

A seminar was held on 6th November 2015, Friday, at 4:30pm in the Ceramic department Seminar Hall. It was of a duration of 20 minutes and saw an audience of 50 plus students. It was in the format of a presentation followed by a brief question and answer round, conducted by Prof. Arvind Kumar. In the seminar, the construction of the electron microscope, its working principle, and the sample preparation methods were discussed elaborately.

This was an initiative taken by NITR, inspired by similar seminars that have been conducted in IIT Roorkee, IIT Kanpur and IISc Bangalore.
