A glance into the boundary lubrication mechanism of PVA hydrogel after the reduction of interstitial fluid pressurization

Friction
The present study introduces a tribological comparison of five polyvinyl alcohol (PVA) hydrogel specimens with different physiological properties and possible candidate materials for cartilage replacement.

Diatom Bionanotribology

, 2004
Organisms experience friction and wear. They have optimized lubrication systems. After all, Nature is an "engineering office" which has been "in business" for millions of years.

Active control of finger sliding friction with different surface roughness in SDS solutions for underwater surface haptics

Friction
Underwater surface haptics based on friction modulation provide new concepts for immersive extended reality haptic technology. A previous study proposed a modulation method by using a voltage-controlled technique in saline solutions, demonstrating that ...

In-situ generated tribomaterial in metal/metal contacts: Current understanding and future implications for implants

, 2017
[EN] Artificial hip joints operate in aqueous biofluids that are highly reactive towards metallic surfaces. The reactivity at the metal interface is enhanced by mechanical interaction due to friction, which can change the near-surface structure of the ...

Effect of Protein (Bovine Serum Albumin) Content on the Frictional Behaviour of Soft Contact Lenses Using a Dynamic Oscillating Tribometer

Applied Sciences
Proteins can adsorb on the surface of materials, such as soft contact lenses (SCLs), and can affect the hydrophobicity, roughness, and surface properties of the contact lenses (CLs), which, in turn, can influence the friction between the lenses and the ...
