The carbon atoms recombine into graphene sheets in the hydrogen atmosphere.

The prepared seven samples (BP01- Graphite, BP02- MoS2, BP03- Graphite &MoS2, BP04- Graphene, BP05- Graphene & Graphite, BP06 - Graphene & MoS2, BP07 - Graphene, Graphite & MoS2) were tested in pin and disc machine and compared to investigate the coefficient of friction, wear resistance followed by hardness test and thermal degradation analysis. ...The friction materials were made in the form of cylindrical pin from three different solid lubricants - graphite, molybdenum disulfide (MoS2) and graphene - keeping the other ingredients fixed.

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.

Our aim is to fabricate organic frictional composites of basalt fiber reinforced polymer composites along with three possible combination of nano - solid lubricants like (1) graphite (2) graphene (3) molybdenum disulfide through hot press technique. The outcome of the tribological tests (by varying load and sliding velocity) indicates that these three-organic fiber-based polymer composites have been effectively modified by nano-solid lubricants leading to significant enhancement.

In this article, the dependence of the soot oxidation rate upon nanostructure, namely the length, separation distance and curvature of the graphene segments is shown. Soots possessing graphitic, fullerenic or amorphous nanostructure are used for this comparison.

In a recent joint paper by the Aerospace Technology Institute (ATI) and the National Graphene Institute (NGI) at the University of Manchester, researchers outlined the disruptive impact potential of graphene applications in aerospace. This comes at a time of marked graphene innovation from research teams in Japan and Singapore. ...In a recent joint paper by the Aerospace Technology Institute (ATI) and the National Graphene Institute (NGI) at the University of Manchester, researchers outlined the disruptive impact potential of graphene applications in aerospace.
