TL;DR: In this article, graphite nanoparticles were used to fabricate nano lubricants with enhanced tribological properties and lubrication characteristics, and the results showed that when comparing fixed plates coated with raw and nano-lubricants, the plate coated with a nano lubricant containing graphite nanarticles had a lower friction coefficient and less wear.

TL;DR: In this paper, the tribological properties of fullerene nanoparticles-added mineral oil were investigated as a function of volume concentration of the nanoparticles, and the results showed that the nano-oil containing the higher volume of nanoparticles resulted in the lower friction coefficient and less wear in the fixed plate, indicating that the increase of nanoparticle additives improved the lubrication properties of regular mineral oil.

TL;DR: In this paper, the friction and anti-wear properties of nano-oil composed of refrigerant oil and fullerene nanoparticles in the sliding thrust bearing of scroll compressors were evaluated.

TL;DR: In this paper, various carbon-based particles such as graphite, carbon black, graphite nanofibers and carbon nanotubes were dispersed in mineral oil to systematically examine the effect of the size and shape of particles on the properties of friction performance.

TL;DR: In this paper, an experimental study was conducted to investigate the chronological performance variation such as pressure drop across a heat exchanger and cooling capacity due to the air-side particulate fouling of fin-and-tube heat exchangers for air conditioner evaporators used.
