CY6998 : Electrochemical Approaches to Functional Supramolecular Systems

Systems Objectives:

The course embodies a combined approach of supramolecular chemistry with electrochemistry that has produced a wealth of interesting functions and devices and their practical applications in energy conversion technology, advanced materials and diagnostics. The objective of the course is to bring forth the current electrochemical research applied to multi-component chemical systems with a special attention to properties and functions. The course, structured for ~ 40 lectures during an even semester, will cater to Ph. D as well as M. Sc / M. Tech graduate students (in a limited sense to B. Techs) who wish to explore the frontiers of electrochemistry with materials and nanosciences.
