Surfaces, Interfaces and Materials Electrochemistry


  The main focus of our research is to understand interfacial properties involving novel materials and modified surfaces. We use a combination of spectroscopy, electrochemistry and microscopy to understand the interfacial properties. Coupled in-situ techniques based on electrochemical FTIR, Raman electrochemistry are routinely used to understand various aspects.
