A brief Account of Research Work

 1) Ph.D. Programme, IPC Department, I.I.Sc.

    Title of Ph.D. Thesis: Mechanistic studies on the combustion and decomposition of solid Composite propellants: Effect of burning rate catalysts.

             Investigation were carried out on a few composite solid propellant systems with a view to understand (i) the role of condensed phase reactions and (ii) the effect and mechanism of action of transition metal oxides on the combustion of propellants.

Post doctoral Research: (i) St. Francis Xavier University Antigonish, Nova Scolia Canada. Studies were solid state oriented involving simple inorganic synthesis, solid-state kinetics construction of phase diagrams and electrical conductivity measurements.

(ii) Department of metallurgy, I.I.Sc. Beneficiation of coal and thermal studies.
