Bioinspired Bottlebrush Polymers for Aqueous Boundary Lubrication. [PDF]
Polymers (Basel), 2022 An extremely efficient lubrication system is achieved in synovial joints by means of bio-lubricants and sophisticated nanostructured surfaces that work together. Molecular bottlebrush structures play crucial roles for this superior tribosystem.

Experimental Investigation of the Tribological Behaviors of Carbon Fiber Reinforced Polymer Composites under Boundary Lubrication. [PDF]
Polymers (Basel), 2022 Friction and wear experiments were performed on carbon fiber-reinforced polymer (CFRP) composites, and the tribological behavior of these materials under boundary lubrication (based on the 5100 4T 10 W-30 engine oil with TiO2 Degussa P25 nanoparticles ...

The Role of Hyaluronic Acid in Cartilage Boundary Lubrication. [PDF]
Cells, 2020 Hydration lubrication has emerged as a new paradigm for lubrication in aqueous and biological media, accounting especially for the extremely low friction (friction coefficients down to 0.001) of articular cartilage lubrication in joints.

MoS2 reinforced PEEK composite for improved aqueous boundary lubrication
Friction, 2023 Polyether-etherketone (PEEK) is a corrosion-resistant material that has been widely used in aqueous lubrication. However, its anti-wear performance must be improved for its application in the industry.

Boundary lubrication of heterogeneous surfaces and the onset of cavitation in frictional contacts. [PDF]
Sci Adv, 2016 Molecular dynamics simulations show that cavitation occurs when liquids flow over surfaces with sticking and slipping domains. Surfaces can be slippery or sticky depending on surface chemistry and roughness.

Supramolecular synergy in the boundary lubrication of synovial joints. [PDF]
Nat Commun, 2015 Hyaluronan, lubricin and phospholipids, molecules ubiquitous in synovial joints, such as hips and knees, have separately been invoked as the lubricants responsible for the remarkable lubrication of articular cartilage; but alone, these molecules cannot ...

Shear-responsive boundary-lubricated hydrogels attenuate osteoarthritis
Bioactive Materials, 2022 Lipid-based boundary layers formed on liposome-containing hydrogels can facilitate lubrication. However, these boundary layers can be damaged by shear, resulting in decreased lubrication.

Construction and Tribological Properties of Biomimetic Cartilage-Lubricating Hydrogels
Gels, 2022 Articular cartilage provides ultralow friction to maintain the physiological function of the knee joint, which arises from the hierarchical complex composed of hyaluronic acid, phospholipids, and lubricin, covering the cartilage surface as boundary ...
