Healthy articular cartilage, covering the ends of bones in major joints such as hips and
knees, presents the most efficiently‐lubricated surface known in nature, with friction …

The major synovial joints such as hips and knees are uniquely efficient tribological systems,
able to articulate over a wide range of shear rates with a friction coefficient between the …

Hyaluronan, lubricin and phospholipids, molecules ubiquitous in synovial joints, such as
hips and knees, have separately been invoked as the lubricants responsible for the …

Hydration lubrication has emerged as a new paradigm for lubrication in aqueous and
biological media, accounting especially for the extremely low friction (friction coefficients …

Applying nanomaterials and nanotechnology in lubrication has become increasingly
popular and important to further reduce the friction and wear in engineering applications. To …

Osteoarthritis leads to an alteration in the composition of the synovial fluid, which is
associated with an increase in friction and the progressive and irreversible destruction of the …

Osteoarthritic joints contain lower-molecular-weight (MW) hyaluronan (hyaluronic acid, HA)
than healthy joints. To understand the relevance of this HA size effect for joint lubrication, the …

Mucins are long glycoprotein molecules responsible for the gel nature of the mucous layer
that covers epithelial surfaces throughout the body. Mucins, as the major salivary proteins …

The quality of the lubricant between cartilaginous joint surfaces impacts the joint's
mechanistic properties. In this study, we define the biochemical, ultrastructural, and …

The majority of artificial joints incorporate biomedical grade Ultra High Molecular Weight
Poly Ethylene (UHMWPE), whose wear is considered most important in controlling service …
