Recent Progress in Cartilage Lubrication [PDF]

Advances in Materials, 2021
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 coefficients as low as 0.001 up to physiologically high pressures.

Motion lubrication suppressed mechanical activation via hydrated fibrous gene patch for tendon healing

Science Advances, 2023
Mechanical activation of fibroblasts, caused by friction and transforming growth factor–β1 recognition, is one of the main causes of tissue adhesions. In this study, we developed a lubricated gene-hydrogel patch, which provides both a motion lubrication ...

Hydration Lubrication in Biomedical Applications: From Cartilage to Hydrogels

Accounts of Materials Research, 2022
Conspectus In the course of evolution, nature has achieved remarkably lubricated surfaces, with healthy articular cartilage in the major (synovial) joints being the prime example, that can last a lifetime as they slide past each other with ultralow ...

Molecular dynamics simulation of the Stribeck curve: Boundary lubrication, mixed lubrication, and hydrodynamic lubrication on the atomistic level

Friction, 2023
Lubricated contact processes are studied using classical molecular dynamics simulations for determining the entire range of the Stribeck curve. Therefore, the lateral movement of two solid bodies at different gap height are studied. In each simulation, a

Biomimetic injectable hydrogel microspheres with enhanced lubrication and controllable drug release for the treatment of osteoarthritis

Bioactive Materials, 2021
The occurrence of osteoarthritis (OA) is highly associated with the reduced lubrication property of the joint, where a progressive and irreversible damage of the articular cartilage and consecutive inflammatory response dominate the mechanism.

Cryogenic minimum quantity lubrication machining: from mechanism to application

Frontiers of Mechanical Engineering, 2021
Cutting fluid plays a cooling-lubrication role in the cutting of metal materials. However, the substantial usage of cutting fluid in traditional flood machining seriously pollutes the environment and threatens the health of workers.

Minimum quantity lubrication machining of aeronautical materials using carbon group nanolubricant: From mechanisms to application

Chinese Journal of Aeronautics, 2021
It is an inevitable trend of sustainable manufacturing to replace flood and dry machining with minimum quantity lubrication (MQL) technology. Nevertheless, for aeronautical difficult-to-machine materials, MQL couldn’t meet the high demand of cooling and ...

The air gap between tape and drum in a video recorder [PDF]

, 1991
Lubrication with ambient air is not quite generally applied. The best known application is the "oil bearing" in tape recording systems for audio, video and computer applications; where the gap height that is needed for effective lubrication may quite ...
