Expert in Rubber Chemistry and Technology, Polymer synthesis, Organic synthesis, Nanotechnology, Surface chem.
• Characterization of the raw material using various analytical techniques such as ATR-FTIR, X-Ray Photoelectron spectroscopy, SEM/EDXS(for Morphology Assessment), FTIR- Mass Spectroscopy, Thermogravimetric analysis (Thermal stability) and Differential Scanning calorimetry (glass transition temperature).
• Treatment of Crude rubber (SBR/NR) with Si69 (S Crosslinker) and sulfonyl amide for relative optimization and characterization of the treated sample with the non treated sample using the techniques mentioned above (primarily FTIR) and TGA
• Functionalization of used tire rubber by hydrosilylation by the platinum catalyzed (Kartsteds catalyst) as well as autocatalyzed reactions and supplying these samples after characterization by the above mentioned analytical tools to Michelin for tire formulation, compounding and testing (properties such as uncure /cure properties, shore A test Rheometry, Dynamic Mechanical analysis)
Michelin patented this technology in the year 2006 on increasing the property values in new tires by including this functionalized used tire rubber.
Lehigh Technlogies LLC ( Leading manufacturer of cryogenic ground tire rubber)
• His work with Lehigh illustrated that used tire rubber powder( SBR-NR/ Nitrile Rubber) can be used to increase the property values in most rubber products, including new tires, extending its usefulness beyond just an added
filler. With this study, tire manufacturers worldwide have a viable alternative ingredient that can be used to make ‘green’ tires, while at the same time enhancing the performance of the tire.
• LLDPE films filled with 2.5 wt (%) and 5.0 wt (%) UTR were provided by Lehigh. The objective was to characterize the films to evaluate the possibility of interaction between UTR and LLDPE, if any.
• He along with his PI observed that these specially ground rubber possess enormous potential as a filler and effect the cure kinetic behavior of the epoxy resin. The resulting composites were demonstrated to have higher mechanical properties as compared with the epoxy composites without any rubber in it.
• Most important finding was the identification of stable free radicals present in these used tire rubber using electron paramagnetic resonance spectroscopy (EPR) which was utilized as a free radical source in his research with used tire rubber surface grafting with vinyl containing monomers.
CIVIL ENGINEERING (ASPHALT ARTS AND TECHNOLOGY SERVICES) He worked with a group of civil engineers where he provided them the autocatalyzed used tire rubber to be used in asphalt for pavement applicationSurface grafted recycled used tire rubber (SBR/ NR) and (nitrile rubber) with acrylic acid and did rheology testing on the asphalt-rubber binder for construction and pavement application.

Leading cryogenically grounded recycled ground tire rubber (GTR) particles manufacturers
• He developed a recycling approach to utilize the recycled tire rubbers
• LLDPE films filled with 2.5 wt (%) and 5.0 wt (%) ground tire rubber (GTR) were extruded and provided by Lehigh. The objective was to characterize the films to evaluate the possibility of interaction between GTR and LLDPE, if any.
• He utilized these GTR as a filler material for composite formulations. The resulting composites have higher mechanical properties as compared with the epoxy based resin composites without any rubber in it. Other resins such as polyester resin were utilized as well for the research
•Most important finding during his research was the identification of stable free radicals present in these used tire rubber using electron paramagnetic resonance spectroscopy (EPR) which was utilized as a free radical source in his further research with used tire rubber surface chemical modification/grafting with vinyl containing monomers (acrylates) and F2 gas.
