Technology
NIS specialized in commercial manufacturing of nanoparticles of Inorganic Fullerene-like Tungsten Disulfide (IF-WS2). The particles are called Inorganic Fullerene-like (IF), because of the near spherical geometry and a hollow core – similar to carbon fullerenes. The name “fullerenes” or “buckyballs” came from the architectural modeler Richard Buckminster Fuller, who popularized the geodesic dome. Professor Reshef Tenne discovered Inorganic Fullerene-like nanoparticles (IF-MXy where M- is transition metal and X - is chalcogen group) at the Weizmann Institute of Science in 1992. The diameter of the primary particle can range between 20 – 280 nm. IF-WS2 nanoparticles with a hollow sphere (Fullerene-like) morphology, provide extreme lubricity, anti-friction, and high impact resistance (up to 35 GPa).
Unlike standard solids that have platelet-like structures with moderate tribological properties, IF-WS2 particles have tens of caged concentric layers, making these particles excel under extreme pressure or load, thus significantly reducing friction and wear.

Products
IF-WS2 Formulated
In late 2018 APNano and NIS have undergone substantial structural changes, updating the product line and changing the name from “NanoLub” to “IF-WS2 Formulated.” IF-WS2 formulations are designed to lower friction and operating temperature, thereby reducing mechanical wear. At the same time, contact pressure causes submicron spheres of IF-WS2 to release tribofilms that attach to surface, reduce wear and filling asperities and smooth them, improving overall efficiency while extending machinery life.

The company offered industrial lubricant additives and tribological packages based on IF-WS2 particles. The additives were also available as a dispersion in oil, water, and solvent. Possible applications include, but not limited to, lubricants, grease, metalworking fluids, coatings, paints, and polymers used in mining, marine, heavy machinery, power station, space, and military industrial sectors.
