Research Areas

We are interested in several areas of research, but they may be broadly classified as     

  • Polymer reactions, primarily polymer degradation
  • Supercritical fluids
  • Catalytic Reactions
  • Continuous distribution kinetics for transport processes and separation processes

 To the best of our knowledge of the peer-reviewed published literature, we have developed, for the first time in the world, several new processes and modeling techniques. Listed below is a selected list among them,

·        Degradation of polymers in supercritical benzene/toluene etc.

·        Degradation of polymers with combustion synthesized catalyst under UV exposure

·        Thermal degradation of polymers with combustion-synthesized catalysts

·        Degradation of polymers with combined ultrasound and ultraviolet exposure

·        Simultaneous polymerization and degradation under ultrasound
