Physicochemical and tribological properties of gemini-type halogen-free dicationic ionic liquids

Friction, 2020
A series of new halogen-free dicationic ionic liquids (ILs) with different alkyl chain lengths were prepared, and the relationship between the alkyl chain length, physicochemical and tribological properties of ILs, and their role as neat lubricant for ...

Oil-soluble ionic liquids as antiwear and extreme pressure additives in poly-α-olefin for steel/steel contacts

Friction, 2017
To enhance the lubricating and extreme pressure (EP) performance of base oils, two types of oil-soluble ionic liquids (ILs) with similar anion albeit dissimilar cations were synthesized. The physical properties of the prepared ILs were measured.

Joint Lubrication with Artificial Lubricants [PDF]

Arthritis & Rheumatism, 1971
AbstractThe joint lubricating properties, in vitro, in bovine metatarsal‐phalangeal joints, of silicone fluid, methyl cellulose and polyvinyl‐pyrrolidone were compared to buffer, serum and synovial fluid. As had been previously reported, synovial fluid was almost twice as good as serum and buffer, which are equivalent in their joint lubricating ...

MoS2 nanoparticles grown on carbon nanomaterials for lubricating oil additives

Friction, 2020
In this study, the nanocomposites of MoS2 nanoparticles (NPs) grown on carbon nanotubes (MoS2@CNT), graphene (MoS2@Gr), and fullerene C60 (MoS2@C60) were synthesized, characterized, and evaluated for potential use as lubricant additives.
