Superlubricity of polyethylene glycol solutions: Running-in effects, thickness changes, and rheology

Friction
The role of additives in liquid superlubricity is regarded as a crucial element of the running-in process due to their role in reducing friction. Nevertheless, there has been minor investigation into rheological changes that occur during the process ...

Differential hydration lubrication performance of polyelectrolyte-modified UHMWPE promoted by diverse charge characteristics

Friction
Hydrated ions can achieve exceptional hydration lubrication through their adsorption onto oppositely charged surfaces. Similarly, the charge characteristics of polyelectrolytes are expected to significantly impact the hydration lubrication performance of

Combination of diketone and PAO to achieve macroscale oil-based superlubricity at relative high contact pressures

Friction
1-(4-ethylphenyl)-nonane-1,3-dione (0206) is an oil-soluble liquid molecule with rod-like structure. In this study, the chelate (0206-Fe) with octahedral structure was prepared by the reaction of ferric chloride and 1,3-diketone. The experimental results

Sliding Over Graphene Grain Boundaries: A Step Towards Macroscale Superlubricity

, 2020
In light of the race towards macroscale superlubricity of graphitic contacts, the effect of grain boundaries on their frictional properties becomes of central importance. Here, we elucidate the unique frictional mechanisms characterizing topological defects along typical grain boundaries that can vary from being nearly flat to highly corrugated ...
