“…4,5 They further improved the tribological performances of the lubricant by surface modications that largely increase the dispersion stability of copper nanoparticle. [6][7][8][9] The existing researches illustrate that copper nanoparticle as an additive could signicantly improve the tribological properties of lubricants, which may achieve the required lubrication of equipment.…”

In the present study, triangular copper nanoplates have been prepared with CTAB as the capping reagent and ascorbic acid as the reductant. This study also provides quantitative analyses on the effects of pH and CTAB on the structural characteristics of the nanoplates. When the reaction takes place at a pH ¼ 7 with a CTAB concentration of 0.06 M, the resulting triangular nanoplates appear to have well-defined and identical structures. As an additive for greases, the nanoplates are responsible for the formation of a film deposit at the interface of the friction pair during friction. The effects of which are a 12% drop in the friction coefficient of the grease and an 82.2% drop in wear loss, which, in turn, significantly improve the tribological properties of the lubricant.

Anatase (TiO 2 ) nanoparticles with an average diameter of 10 nm were synthesized by solvothermal method followed by surface modification with stearic acid (SA). As-prepared, the nanoparticles (SA-TiO 2 ) were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FT-IR), and thermogravimetry (TGA) and differential scanning calorimetry (DSC). The tribological properties of SA-TiO 2 as an additive of liquid paraffin (LP) were evaluated by a fourball tester. The results show that LP with SA-TiO 2 exhibited good anti-wear and friction-reduction properties under the all applied loads. Comparing LP with LP-containing SA, LP-containing TiO 2 , and LP-containing SA-TiO 2 , the LP-containing SA-TiO 2 had the best load-carrying capacity. It was deduced that the boundary lubricating film was mainly composed of TiO 2 deposits and an adsorbing film of SA which contribute to the excellent lubricating effect of SA-TiO 2 in LP.

“…Thus, they easily form boundary layers of low shearing strength at the frictional surfaces, to reduce the friction coefficient and to repair the worn surface through deposition at more severe conditions [104]. Xue et al have proposed the tribochemistry and antiwear mechanism of organic-inorganic nanoparticles, such as the dialkyldithiophosphate coated Cu, Ag, LaF 3 , and the organic acid coated TiO 2 nanoparticles as lubricant additives at different lubricating regimes [105]. The schematic lubricating mechanisms are demonstrated in Fig.…”

Friction exists wherever relative motion occurs and is the main source of energy consumption. Lubrication plays a significant role in improving fuel efficiency, reducing emissions, and prolonging the service life of machines. Surface interactions between two moving solid surfaces or the flow of a fluid (and/or environment) on a solid surface are the primary causes of friction. Apart from the mechanical design of moving parts, surface physicochemistry is of crucial importance to lubrication. This review deals with the frontier research on controlling friction and lubrication, highlights the importance of physicochemistry aspects, and enumerates the state-of-the-art chemistry solutions to tribological issues. It aims at inspiring talented young scientists from different fields to make significant contributions to the area.
