DESCRIPTION :

The research focus of my group is mainly on the development of corrosion resistant coatings of ceramic, polymer, composites, graphene, carbon nanotubes, and tribological coatings, thermal barrier coatings, etc for application in oil and gas, aerospace, chemical and metallurgical industries, hydrophobic/ superhydrophobic coatings, development of Solid Oxide Fuel cells (SOFC) technology as a future energy generation system that will use hydrogen and biogas as fuel thereby minimizing the use of fossil fuels and help in CO2 sequestration. I mainly use Electrophoretic deposition (EPD), High Velocity Oxy Fuel (HVOF) and Cold Spray (CS) coating  for development of advanced coatings for industrial applications. 

My recent research is on synthesis, characterization and application of MXenes, a relatively new class of two-dimensional (2D) transition-metal carbides, carbonitrides, and nitrides, discovered in 2011 in Drexel University, that exhibit exceptionally unique properties such as high electronic conductivity, a wide range of optical characteristics, hydrophilicity, and mechanical stability. MXenes have shown promise in many applications, such as energy storage, energy storage including super capacitors, lithium-ion batteries, oxygen evolution reaction, heavy metal adsorption, water purification, electrocatalysis, medicine, and transparent coatings. We are now working on 2D titanium carbide (Ti3C2Tx) that has the highest electronic conductivity exceeding 10,000 S cm−1.

• 1. Dewatering of radioactive sludge by flocculation This work relates to flocculation and dewatering to enhance solid-liquid separation problem of waste water of fuel processing plant of Bhabha Atomic Research Center. This technology is not licensed, but BARC is using it now for dewatering of radioactive sludges. The waste water from the fuel processing plant contains dissolved radioactive elements like CS137 and Sr90 . They cannot be discharged directly into any water body. These dissolved species are typically co-precipitated onto chemical sludges like copper ferrocyanide, barium sulphate of ferric chloride. However the suspension is very stable and it does not settle. It is essential to increase sedimentation of these sludge and reduce sludge volume so that it can be compacted and encapsulated in containers and buried in the soil for radioactive decay. In this project, we incorporated suitable indigeneous polyacrylamide based flocculants, which not only improved flocculation (increased settling rate and reduced sludge volume) but also adsorbed CS137 and Sr90 ions which was an added benefit. The process is currently being adopted in BARC.
