Abstract: System for conducting measurements of friction of a chosen material with reduced errors. The system includes a sample holder, a bushing accommodating such holder while permitting reversible repositioning of the holder along a bushing axis, a horizontal force sensor, a vertical force sensor, a sample holder pusher and a subsystem including a linear vertical bearing (disposed in the bushing and separating the holder from the bushing) and/or a horizontally-sliding element between the rod pusher and the vertical force sensor. The subsystem is structured to reduce a rocking motion of the holder in the bushing caused by a relative motion between the sample and an auxiliary body brought in contact with the sample. The method for performing measurements with such system.

Abstract: A nanocomposite coating that in turn extract self-replenishing (or -healing), superlubricious carbon film directly from natural gas or hydrocarbon gas in mechanical systems. The coating deposits on sealing and sliding surfaces reducing friction and wear. The result is a reduction in inefficiency, machine breakdown, and adverse environmental impact.

Abstract: A lubricant composition includes an oil including a plurality of long-chain hydrocarbon molecules. A quantity of a catalytically active metal-organic additive is mixed with the oil. The metal-organic additive is formulated to fragment the long-chain hydrocarbon molecules of the oil into at least one of dimers and trimers under the influence of at least one of a mechanical loading and a thermal loading. In some embodiments, the metal-organic additive includes a compound of formula II: where: X is Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg or Cn, and R1, R2, R3 and R4 are alkyl or alkyl halide.
