Research Interest
Materials science and engineering with special reference to ceramic membrane. ( specially Inorganic membrane like alumina and zeolite membranes). Nano powders preparation by sonochemical, hydrothermal, microemulsion etc methods and their processing by tape casting, hydrothermal coating, sol �gel coating are the area of interests. Clean energy related area like production of hydrogen and storage of hydrogen are the newer area of interest.
