“Grease-based lubricant." "Product type: Surface-reconditioning nano-lubricant grease additives.” "Active material: WS₂multi-layered fullerene solution." "Reducing friction beyond the capacity of other conventional extreme pressure (EP) grease additives."

"The efficacy of inorganic fullerene-like (IF) tungsten disulfide (WS2) nanoparticles as engine oil friction modifier additive was investigated using a high-stroke reciprocating piston ring–cylinder bore bench test system. Frictional characteristics of various IF-WS2 nanoparticle concentrations in mineral oil were experimentally analyzed in simulated engine conditions controlling oil temperature, speed, and normal load. Though the effect of IF-WS2 nanoparticles on piston ring and cylinder bore friction was minor in low concentrations, after a running period in a mixed lubrication regime with 10% additive, a considerable reduction in friction coefficient was observed when the IF-WS2 formulated oil was use." Gullac and Akalin (2010)

"In the past few years, WS2 and MoS2 nanoparticles (IF) with structures closely related to (nested) carbon fullerenes and nanotubes have been synthesized. It was shown before that addition of a small amounts of such nanoparticles to lubricating fluid largely improve the tribological properties of contact surfaces. In the present work, impregnation of the nanoparticles into a porous powder (bronze–graphite) matrix is demonstrated." Rapoport et al. (2001)
