Self-healing anticorrosive coatings for corrosion protection of mild steel is one of the major focus areas of our research. In addition we work on development of new processes and chemicals for corrosion prevention and mitigation.Organic corrosion inhibitors and polymeric coatings for corrosion protection of metals is focus my current research interests. We are doing structural modification of polymer molecules by incorporation of corrosion inhibitors in the molecular structure of acrylic monomers. The resultant polymeric corrosion inhibitors provide excellent adhesion and corrosion inhibition efficiency due to chemisorptions of polymer on metal surface. We have successfully developed and commercialized polymeric coatings for copper alloys, Aluminium alloys and silver.  Replacement of toxic chemicals like cyanide and Cr(IV) with environment friendly chemicals for use in metal surface treatment industry is another focus of my research.In addition, we are working on development of a process to prepare coke from non-coking coal using natural product additives without using any coking coal.For my publications, please visit my Google Scholar site https://scholar.google.co.in/citations?user=6-ymYWgAAAAJ&hl=en
