The online workshop was hosted on Google Meet platform. Dr. Raju Panthagani, Associate Professor, Geethanjali College of Engineering and Technology (GCET), Hyderabad was the resource person. Dr. Dhanya Johnson, Assistant professor, Department of Physics, welcomed the resource person and the participants to the workshop. The workshop was aimed at acquainting the faculty and students with online virtual laboratories, which is of great significance nowadays especially in the context of covid-19 pandemic. Dr.Raju Panthagani started the session by introducing the website - www.tinkercad.com wherein one can build virtual circuits and perform experiments on them. He demonstrated these steps by building a simple LED circuit to start with and then moved on to more complex circuits like CE and CB configuration, zener diode, half wave and full wave rectifiers etc. A free plotting software- Magic plot was also introduced. The speaker then introduced a second website www.falstad.com which could also be used for virtual electronic experiments. The session came to an end by 11:15 AM and was followed by a discussion for about 45 minutes in which the resource person addressed the questions posed by the participants. Dr. Regina Jose officially proposed vote of thanks for the entire session.

The webinar was hosted on the Google Meet platform. Due to technical glitches, the webinar started half an hour behind the schedule. The coordinator Dr. Mini Krishna K welcomed the resource person and the participants to the webinar. The speaker started the session by explaining the various criteria for good quality diffraction data. He then discussed in detail the factors affecting the accuracy and precision of results, which includes the contributions from the sample, instrument, sample preparation errors and data analysis errors. The effect of particle size on the diffraction data was discussed and the methods to minimize the errors from sample preparation were suggested. Various diffractometer geometries were introduced and the importance of suitable optics on the characterization process was explained. Data analysis was discussed on the basis of comparison with the standard databases and profile fitting methods. Towards the end the speaker familiarized the participants to the vital parts of a latest good quality spectrometer in their laboratory.
