Supramolecular Lubricating Hydrogel Microspheres Reshape Damaged Matrix Regeneration. [PDF]

Adv Sci (Weinh)
The supramolecular lubricating hydrogel microspheres can provide stable mechanophysical protection at damaged matrix through interfacial hydration lubrication: in the early and middle stages, microspheres can actively provide microscale supramolecular lubrication (µ ≈ 0.04) for damaged matrix; in the late stage, the wear debris induced by shear and ...

Synthesis of Biolubricant Basestocks from Epoxidized Soybean Oil [PDF]

Catalysts, 2017
This work deals with the preparation of biolubricant basestocks through the ring-opening reaction of epoxidized soybean oil (ESO) by alcohols in presence of solid acid catalysts (SAC-13 resin). To this end, different experimental runs were carried out in a lab-scale reactor, analyzing the effect of the alcohol (methanol, ethanol, 2-propanol, 2-butanol),

Synthesis, reactivity and application studies for different biolubricants [PDF]

Chemistry Central Journal, 2014
Les huiles végétales ont des propriétés uniques différentes en raison de leur structure chimique unique. Les huiles végétales ont une plus grande capacité à lubrifier et ont des indices de viscosité plus élevés. Par conséquent, ils sont examinés de plus près en tant qu'huile de base pour les biolubrifiants et les fluides fonctionnels.
