FTIR studies have confirmed the presence of -C=C at wavenumber of 1652 cm-1 and demonstrates the formation of graphene. It was observed that the quality of exfoliated graphite and yield were improved from the present method of processing of graphene nanosheets. ...It was observed that the quality of exfoliated graphite and yield were improved from the present method of processing of graphene nanosheets. Further, the process time is less when compared with existing conventional methods.

The reaction chamber contains reactants of copper oxides (0.75-0.80 grams) as catalysts and graphene oxide (115-120 grams) as reducing agents in powder form. The reaction has been performed in a closed atmosphere for a period of eight to ten hours and the temperature is maintained at 300°C approximately.

The research on reducing emissions from automotive engines through modifications in the combustion mode and the fuel type is gaining momentum because of the increasing contribution to global warming by the transportation sector. The combustion and emission formation in the advanced low temperature combustion (LTC) engine strategies are susceptible to fuel molecular composition and properties. Ignition timing in LTC strategies is primarily controlled by fuel composition and associated chemical kinetics. Thus, tailoring of fuel properties is required to address the limitations of LTC in terms of lack of control on ignition timing and narrow engine operating load range. Utilizing fuel blends and additives such as nanoparticles is a promising approach to achieving targeted fuel property. An improved understanding of fundamental processes, including fuel evaporation, is required due to its role in fuel-air mixing and emission formation in LTC.
