Hello there!!!
Here is a copy of the presentation that I gave at the Regional Training Institute, Southern Region, C.P.W.D., in a training programme held for Junior Engineers of Civil and Electrical wings of the department on the 13th of February 2015. I had already given a similar presentation in an earlier training programme in the same centre but this presentation improves upon it with applications of nanomaterials in electronics engineering being added to that. hope you find this useful.
