Research progress of cartilage lubrication and biomimetic cartilage lubrication materials
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]
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
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 ...

Numerical Wear Modeling in the Mixed and Boundary Lubrication Regime
The increasing use of low-viscosity lubricants in order to reduce the friction in machine elements such as rolling bearings is leading to increased operation in the mixed or boundary lubrication regime.
