The tribological properties of zinc borate ultrafine powder as a lubricant additive in sunflower oil [PDF]
, 2014 This paper presents an investigation on the tribological properties of zinc borate ultrafine powder employed as a lubricant additive in sunflower oil. The stable dispersions of 0.5 wt%, 1 wt% and 2 wt% zinc borate ultrafine powder in sunflower oil were ...

Wear Behaviour of Nanocrystalline Fe88Si12 Alloy in Water Environment
Advances in Materials Science and Engineering, Volume 2014, Issue 1, 2014., 2014 Wear behaviour of nanocrystalline Fe88Si12 alloy has been investigated in water environment compared with the coarse grained counterpart. The friction coefficient of the Fe88Si12 alloy changes slightly with the grain size. The wear resistance is enhanced as the grain size decreases first and then reduces when the grain size continues to decrease ...

On the mechanism of ZDDP antiwear film formation [PDF]
, 2016 Zinc dialkyldithiophosphate additives are used to control wear and inhibit oxidation in almost all engine oils as well as many other types of lubricant. They limit wear primarily by forming a thick, protective, phosphate glass-based tribofilm on rubbing ...

Riboflavin‐Catalyzed Photoinduced Atom Transfer Radical Polymerization
Macromolecular Chemistry and Physics, Volume 226, Issue 7, April 2025.PhotoATRP of methyl acrylate with riboflavin (RF) and CuBr2/Me6TREN as a dual catalytic system is successfully carried out under a green LED light. The process demonstrated high chain‐end fidelity, efficient oxygen tolerance, and controlled polymerization kinetics, driven primarily by reductive quenching of RF.

The effect of an organic pentasulfide EP additive in turning and milling operations [PDF]
, 2014 Coopération avec Ecole Centrale LyonBecause a cutting fluid could be equally used for different cutting operations, this study proposed to investigate the behavior of a well-known extreme-pressure additive (pentasulfide) in both turning and milling ...

Superlubricity and tribochemistry of polyhydric alcohols [PDF]
Physical Review B, 2008 The anomalous low friction of diamondlike carbon coated surfaces lubricated by pure glycerol was observed at 80 °C. Steel surfaces were coated with an ultrahard 1 µm thick hydrogen-free tetrahedral coordinated carbon (ta-C) layer produced by physical vapor deposition.

Valorisation of glycerol by new mechanochemical processes [PDF]
, 2019 The search for new applications of glycerol, as a chemical platform from which a broad spectrum of new valuable derivatives can be obtained, is ongoing. In the present communication, a new mechano-chemical reactor is used for the valorisation of glycerol,
