Abstract: Certain exemplary embodiments can provide a system, which can comprise ink or a rubber object comprising reactive graphene. The reactive graphene comprises a graphene core that is chemically bonded with a reactive shell. The graphene core is a graphene hybrid composite comprising graphene and one or more of nanocarbon, graphene nanoplatelets, graphene oxide, reduced graphene oxide and/or pristine graphene, etc.

Abstract: A heat dissipator for an electric motor includes an impeller having an internal heat transfer mechanism. The heat transfer mechanism provides efficient heat transfer from the motor armature to the surrounding environment without forcing cooling fluids into the motor and without transferring heat through the motor housing. The motor can therefore be encased in sealed, light-weight plastic motor housing having relatively poor heat transfer characteristics without danger of overheating. The impeller is preferably designed to displace fluids without turbulence, thereby reducing noise and increasing efficiency. To this end, the impeller employs annular disks stacked on a shaft which may be rotatably mounted in a specially shaped housing and which preferably is formed from an extension of the motor drive shaft. The disks and a complementary surface cooperate so as to use a combination of surface friction, centrifugal forces, and a venturi effect to propel fluids without turbulence.
