摘要： Newly discovered allotrope of carbon having a multilayered nanocarbon array exhibits among other properties exceptional stability, electrical conductivity and electromagnetic frequency (emf) attenuation characteristics. Members of this new allotrope include nanocarbon structures possessing vast electron delocalization in multiple directions unavailable to known fullerene-characterized materials like carbon nano-onions (CNOs), multiwalled carbon nano-tubes (MWNTs), graphene, carbon nano-horns, and carbon nano-ellipsoids such that stabilizing electron delocalization crosses or proceeds between layers as well as along layers in multiple directions within a continuous cyclic structure having an advanced interlayer connectivity bonding system involving the whole carbon array apart from incidental defects.

摘要： An engine oil additive includes carbon nanotubes and boron nitride particulates dispersed within a fluid. The additive is configured to be mixed with a quantity of oil such that the quantity of oil has a concentration from 0.05 to 0.5 grams of carbon nanotubes and of boron nitride particulates per quart of oil to improve the lubricity of the oil. The additive improves the horsepower and torque of the engine while reducing fuel consumption. The carbon nanotubes have an —OH functionalized exterior surface. The carbon nanotubes have a diameter from 1 nanometer to 50 nanometers and have a length from 1 micron to 1000 microns. The boron nitride particulates are hex-boron nitride structures having an average size from 30 nanometers to 500 nanometers.

摘要： Graphenic carbon nanoparticles that are dispersed in solvents through the use of dispersant resins are disclosed. The graphenic carbon nanoparticles may be milled prior to dispersion. The dispersant resins may comprise a polymeric dispersant resin comprising an addition polymer comprising the residue of a vinyl heterocyclic amide, an addition polymer comprising a homopolymer, a block (co)polymer, a random (co)polymer, an alternating (co)polymer, a graft (co)polymer, a brush (co)polymer, a star (co)polymer, a telechelic (co)polymer, or a combination thereof. The solvents may be aqueous, non-aqueous, inorganic and/or organic solvents. The dispersions are highly stable and may contain relatively high loadings of the graphenic carbon nanoparticles.
