Dr. V. Ganesh is a Scientist at Central Electrochemical Research Institute (CECRI), Karaikudi; working in the area of Electrodics and Electrocatalysis. He obtained his M.Sc (chemistry) degree from The American College, Madurai and Ph.D. (Chemistry) from Raman Research Institute (RRI), Bangalore, India. He did his postdoctoral studies at University of Edinburgh, Scotland (UK) and he is also a visiting researcher at University of Manitoba, Winnipeg, (Canada). He joined CECRI as a scientist in the year 2009.
His core areas of expertise includes Electrochemistry, Surface chemistry, Electro-analytical chemistry, Electron transfer studies across electrode-electrolyte Interface, Surface modification of metals, semiconductors and oxide materials for sensing and catalytic applications, Biosensors and bio-electrochemistry, Electrochemical enzymatic catalysis, Microbial fuel cells, Self-assembled monolayers (SAMs): structural aspects and applications, Supercapacitors, Oxygen reduction catalysis, Electrochemical tools for health care and diagnostics, Template electrodeposition, Magnetoelectrolysis, Electrochemical studies using microemulsion and liquid crystalline phase systems, Scanning probe microscopy.
For the purposes of understanding and analyzing the electrical, compositional, and structural aspects relevant to the electrochemical reactions that occur in electrochemical cells, a brief description of the evolution of the theoretical aspects of the structure of the double layer, as applied to electrode/electrolyte interfaces, across which charge transfer reactions occur, was presented in this lecture.
Helmholtz Model, Gouy Chapman Model, Stern Model and Devanathan Model are the different proposed structures of electric double layers that were discussed in detail. Faraday’s Law and Butler Volmer equation, Faradaic and Non Faradaic processes, charge transfer and mass transfer kinetics and the significance of polarization was explored in depth. Several analytical techniques such as Impedance spectroscopy, Cyclic Voltametry and Microscopic Techniques such as Scanning Tunnelling Microscopy and Atomic Force Microscopy were also discussed. This talk also featured his current work on Quantum dots and Self Assembled Monolayer (SAM) for improved Bio sensors. Electrochemical bio-sensing is an important branch in biosensing as it enables label free detection of metabolites with important applications to many fields of biomedical diagnostics.
