| Outline of Annual Research Achievements |
1. Graphene oxide based non-metallic multilayered coatings developed on steel substrates for the coating applications in pressure regulator, flow regulator and stop valves in the hydrogen storage and distribution systems.
2. First time ever, superlubricity (COF < 0.002) is observed for graphene oxide based coatings
3. Onion-Like Carbon (OLC) nanoparticles were found to be generated during sliding of graphene oxide in dry nitrogen and hydrogen, while humid atmosphere destroys the OLC particles.
5. The mechanism or science behind the evolution of nanoparticles during sliding was investigated using DFT simulations.
7. Two journal papers (ACS Applied material and interfaces) and six conference proceedings were produced from this project.
