Recent development in understanding the role of lipids in cartilage lubrication

open access: yesFriction
Lubrication deficiency in articular cartilage (AC) triggers irreversible and progressive degradation of AC, termed osteoarthritis (OA). Bio-lubrication-based strategies have been proposed as effective ways to restore temporary cartilage lubrication for ...

Effects of magnetic ionic liquid as a lubricant on the friction and wear behavior of a steel-steel sliding contact under elevated temperatures

open access: yesFriction, 2019
A magnetic ionic liquid (abridged as MIL) [C6mim]5[Dy(SCN)8] was prepared and used as the magnetic lubricant of a steel-steel sliding pair. The tribological properties of the as-prepared MIL were evaluated with a commercially obtained magnetic fluid ...

Adaptive mechanically controlled lubrication mechanism found in articular joints [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
Articular cartilage is a highly efficacious water-based tribological system that is optimized to provide low friction and wear protection at both low and high loads (pressures) and sliding velocities that must last over a lifetime. Although many different lubrication mechanisms have been proposed, it is becoming increasingly apparent that the ...

Mechanochemistry mechanism of lubrication recovery and wear maps of base oil

open access: yesFriction
Lubrication recovery has been observed in tribology research. This refers to the recovery of oil lubrication on a metal after failure or semi-failure by waiting for a period. Past studies attributed this recovery to metal oxidation. However, this article
