Bioinspired Bottlebrush Polymers for Aqueous Boundary Lubrication [PDF]
Polymers, 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.

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.

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.

Aqueous boundary lubrication: Molecular mechanisms, design strategy, and terra incognita
Current Opinion in Colloid and Interface Science, 2017 The molecular mechanisms for aqueous boundary lubrication are very different from those in the classic boundary lubrication, originating from the fluidity of the hydration shells surrounding the surfactant and lipid headgroups.

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 ...
