Pleural Lubrication

open access: yesLubricants, 2016
During breathing, the pleural surfaces slide against each other continuously without damage. Pleural liquid and lubricating molecules should provide the lubrication of the sliding surfaces, thus protecting the mesothelium from shear-induced abrasion.

Effect of ZDDP on lubrication mechanisms of linear fatty amines under boundary lubrication conditions

open access: yes, 2020
The tribological behavior of different linear amines blended to PAO4 alone or in combination with ZDDP was investigated under boundary lubrication regime via the coupling of tribometry and XPS measurements.

Study of Effect of Metal Oleates on Mixed and Boundary Lubrication

open access: yesTribology in Industry, 2020
The article presents the results of a study of metal oleates for friction with mixed and boundary lubrication. The objects of study are copper (II), zinc (II), and tin (II) oleates. The boundary friction coefficient in a "steel - steel" friction pair was

Friction in metal-on-metal total disc arthroplasty: effect of ball radius [PDF]

open access: yes, 2012
Total Disc Arthroplasty (TDA) can be used to replace a degenerated intervertebral disc in the spine. There are different designs of prosthetic discs, but one of the most common is a ball-and-socket combination.

The Effect of Steel Electropolishing on the Tribological Behavior of a Steel–Bronze Pair in the Mixed and Boundary Lubrication Regimes

open access: yesLubricants, 2023
Electropolishing at high current densities without agitation of the electrolyte results in a pitting phenomenon that produces dimple-like surface features.

Lubrication properties of graphene under harsh working conditions

open access: yesMaterials Today Advances, 2023
Graphene materials considered to be promising candidates for next-generation lubricants has been explored and summarized extensively, owing to their atomic-level lamellar structure and extremely low interlayer shear van der Waals barrier.

Breakup of diminutive Rayleigh jets [PDF]

open access: yes, 2010
Discharging a liquid from a nozzle at sufficient large velocity leads to a continuous jet that due to capillary forces breaks up into droplets. Here we investigate the formation of microdroplets from the breakup of micron-sized jets with ultra high-speed

Entry behavior into Friction Interface and Forming Unstable Lubricating Accumulation of Graphene Oxide between SUJ2 Ball and Glass Disk under Boundary Lubrication

open access: yesTribology Online, 2020
Carbon nanomaterials have been studied for their promising tribological properties under boundary lubrication. However, the behavior of carbon nanomaterials upon entering narrow friction interfaces under boundary lubrication is poorly understood. In this
