1. A method of altering the sedimentation mechanism of a carbon-based nanolubricant, the method comprising:
adding carbon nanoparticles to a base fluid to obtain a mixture;
mixing the mixture for about 5 minutes using a magnetic stirrer to obtain a suspension; and
dispersing the suspension using a bath ultrasonicator for about 60 minutes to obtain the nanolubricant, wherein the bath ultrasonicator comprises a water bath at a temperature of about 25° C.;
wherein the carbon nanoparticles are selected from the group consisting of graphene (GN), single-walled carbon nanotubes (SWCNTs), and multi-walled carbon nanotubes (MWCNTs).
