Earthworm inspired lubricant self-pumping hydrogel with sustained lubricity at high loading
The development of mechanically robust super-lubrication hydrogel materials with sustained lubricity at high contact pressures is challenging. In this work, inspired by the durable lubricity feature of the earthworm epidermis, a multilevel structural ...

Computing of the Molecular Orientation State of the Lubrication Layer
AbstractThe algorithm and software for computing the order parameter value describing structural sequence in the molecular model of the boundary lubrication layer have been created. It has been shown that computer estimation of a supramolecular self-organization together with a new method of polarization tribometry can enhance the efficiency of new ...

Hybrid Metal–Carbon Ink for Printed Stretchable Temperature Sensors
We prepare conductive inks for temperature sensing with silver flakes and carbon or graphite flakes in a silicone elastomer matrix. Silver dominates the temperature‐dependent conductivity, while the carbon filler network ensures the stability of the conductive pathways and retains function under strain.

Contact mechanics modelling of articular cartilage and applications [PDF]
Osteoarthritis (OA) is a degenerative disease of articular cartilage. The normal cartilage is known to be an excellent bearing material with remarkable lubricating properties and very low frictional co-efficient and wear and generally survives the ...

Near-zero-wear with super-hard WB4 and a self-repairing tribo-chemical layer
Achieving near-zero-wear remains a major challenge in mechanical engineering and material science. Current ultra-low wear materials are typically developed based on the self-consumption strategy.

Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Non-steady state lubrication of counterformal contacts [PDF]
A theoretical study has been undertaken of the phenomenon of non-steady state lubrication of concentrated point and line contacts. This has been based upon a study of the effect of squeeze-film action in both hydrodynamically and elastohydrodynamically ...

Coating‐lubricant combination for improving tribo‐system performance
New tribo-systems composed of green chemicals have been investigated. Compatibility of friction modifiers with DLC was evaluated by using SRV test machine. A Zn-free lubricant formulation showed a steady-state friction coefficient of 0.15 for steel/steel
