Boundary lubrication by adsorption film
Friction, 2015 A complete understanding of the mechanism of boundary lubrication is a goal that scientists have been striving to achieve over the past century. Although this complicated process has been far from fully revealed, a general picture and its influencing ...

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 ...

Research progress of cartilage lubrication and biomimetic cartilage lubrication materials
Frontiers in Bioengineering and Biotechnology, 2022 Human joints move thousands of times a day. The articular cartilage plays a vital role in joints’ protection. If there is dysfunction in cartilage lubrication, cartilage cannot maintain its normal function.

Lipids and lipid-mixtures in boundary layers: from hydration lubrication to osteoarthritis [PDF]
Current Opinion in Colloid & Interface Science, 2021 The hydration layer surrounding the phosphocholine headgroups of single-component phosphatidylcholine (PC) lipids, or of lipid-mixtures, assembled at an interface greatly modifies the interfacial properties and interactions. As water molecules within the

Mixed-lubrication analysis of misaligned journal bearing considering turbulence and cavitation
AIP Advances, 2022 By integrating the average flow equation and Ng–Pan turbulence model using the boundary condition of mass conserving [Jakobsson-Floberg-Olsson (JFO)], a mixed lubrication model for misaligned bearing was established considering the effects of turbulence ...

A Computational Study on the Role of Lubricants under Boundary Lubrication [PDF]
Lubricants, 2023 The knowledge of how lubricants contribute to the operational life of a drive train is unclear until now, despite the fact that plenty of literature is available. A novel concept is presented in order to estimate the wear appearing in bearings addressed to the regime of mixed friction with respect to the composition and the so-called “inner” structure ...

ACS Applied Materials and Interfaces, 2020 Interactions among anti-wear additives (AWs), friction modifiers (FMs), and dispersant in a lubricating oil are critical for tribological performance. This study investigates compatibilities of three oil-soluble ionic liquids (ILs, candidate AWs) with a ...
