Research Interests Combustion chemistry: The focus is on high temperature gas phase chemical kinetics related to combustion processes with a special emphasis on relevance to environmental impact. A very high pressure single pulse shock tube (a chemical shock tube) is used for these studies. The shock tube when coupled to gas chromatography/mass spectrometry permits the examination of stable species formed during the pyrolysis and oxidation of aromatic compounds such as toluene, benzene and phenol, cyclics such as cyclopentadiene and furan and nitrogen/sulfur containing compounds such as pyrrole and the thiols. Furthermore, soot formation processes, of significance to cleaning burning fuels, resulting from the reactions of species like propargyl radical, hexadiyne and diacetylene can be studied in the shock tube at very high pressures. Combustion synthesis of materials: Non-oxide refractory materials such as titanium nitride, silicon nitride, titanium hydride and various carbides are all amenable to synthesis using self sustaining combustion processes. The high but controllable temperatures of the combustion process often lead to higher purity and better quality products. The fundamental nature of solid/gas combustion synthesis processes especially as it impacts the size, shape and composition of small powder particle products are being examined in variable density fluidized beds of metal articles in reactive fluids such as nitrogen. With the addition of microwave heating, these metal particles form nanolayers that have potential catalytic activity for hydrodenitrogenation and desulfurization, the water gas shift reaction and direct fuel oxidation in fuel cells.
