We have developed the new hexamethyldisilazane based synthesis of metal sulphide nanoparticles (e.g Ni₃S₄, Cu₂S, CuS, InP/ZnS, CdSe, Bi₂S₃, In₂S₃, Ag and Ag/Ag₂S. The method is simple one pot synthesis and used cost-effective chemicals for the synthesis of various materials. The method yielded the surface/capping agent free nanoparticles ideal for catalysis and other applications.

We prepared the quantum dots for high efficient light emitting diodes. State-of-art CdSe based quantum dots were prepared and size tuned for high efficiency of the LEDs. I have prepared CdSe nanoparticles with defined size, composition with various morphologies with high quantum yield (~84%) and optimised for the high efficiency (64 lm/Watt). As a part of out come, we published scientific reports and ACS applied materials and interfaces.

We demonstrated microcontact printing using silk, water, and common laboratory solvents. It provides a simple, ecofriendly, recyclable, configurable, and biocompat- ible lithographic technique. Silk-ink interactions and lift-off procedure were optimized to generate the functional structures. The present method offers unusual lithographic capabilities that can be utilized for applications ranging from electronics to biological interfaces.

We developed a novel method for the production of a rare stoichiometric form of nickel sulphide (Ni₃S₄) nanoparticles. The newly developed procedure was simple, single step and scalable for bulk preparation. The method yielded nanoparticles with clean surfaces, which was characterized methodically by various techniques. He has demonstrated a novel HMDS-assisted method of synthesis of Ni₃S₄ nanocatalysts.
