Performance of Poly Alpha Olefin Nanolubricant
The viscosity and tribological behavior of nanofluids formed by dispersed nano-diamond particles within Poly-Alpha-Olefin (PAO6) lubricant is studied at different concentrations. The variation of coefficient of friction with nanoparticle concentration is

Lubrication properties of nylon mixed with lubricants.
Plastics are used widely as sliding parts. In order to investigate the effect of the varied lubricants mixed in the nylon rollers, experimental equipment was designed and manufactured. In the experiment on the friction of the nylon roller, a nylon roller was rotated contacting with a steel roller in the same direction.

Numerical Wear Modeling in the Mixed and Boundary Lubrication Regime
The increasing use of low-viscosity lubricants in order to reduce the friction in machine elements such as rolling bearings is leading to increased operation in the mixed or boundary lubrication regime.
