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 …

Friction is a phenomenon that exists extensively in nature and industry; it has proven
necessary in daily life and beneficial in energy scavenging but is also alleged to be the main …

Superlubricity, the state of ultralow friction between two sliding surfaces, has become a
frontier subject in tribology. Here, a state-of-the-art review of the phenomena and …

Structural superlubricity, a state of ultralow friction and wear between crystalline surfaces, is
a fundamental phenomenon in modern tribology that defines a new approach to lubrication …

The lubrication of hydrogels arises from fluid or solvated surface phases. By contrast, the
lubricity of articular cartilage, a complex biohydrogel, has been at least partially attributed to …

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 …

Recent progress in surface-initiated polymerization enables the deliberate polymer
modification of nanoscopic surfaces with high levels of precision. This has given rise to the …

The major synovial joints such as hips and knees are uniquely efficient tribological systems,
able to articulate over a wide range of shear rates with a friction coefficient between the …

The hydration lubrication paradigm, whereby hydration layers are both strongly held by the
charges they surround, and so can support large pressures without being squeezed out, and …

Lubricated surfaces have shown promise in numerous applications where impinging foreign
droplets must be removed easily; however, before they can be widely adopted, the problem …
