The work relates to development of complex Li based phosphates (LiFePO4) and oxides (doped LiCoO2) for rechargeable Lithium ion batteries using solution plasma spray deposition. The same method has been used for deposition of solid electrolytes of Li-Al-Ti-Phosphate for use in solid state and Li air batteries.This new approach makes use of solution precursors to deposit film based cathodes on current collectors. The method offers unique advantages such as direct deposition and large area films in high throughput. The cathodes and solid electrolytes are made of nanoparticulate matrix and exhibit unique electrochemical properties.

Earlier work related to optical properties of carbon nanotubes. By making use of functionalized nanotubes we have demonstarted the biosensing function for sensing of proteins. In the further work immuno assay studies are demonstrated for protein-antibody detection.Also, I have worked on nanotube-silica based optical composite materials.Integration of Si nanowires for electrical charge transport studies.

Worked on nanotube-fullerene hybrid materials. Their unique structural and material properties have been investigated. Effect of electron beam on nanoscale carbon materials (single, double-wall carbon nanotubes, nano peapods) has been investigated. Nanotube material processing and purification.
