Ball Milled Graphene Nano Additives for Enhancing Sliding Contact in Vegetable Oil

Nanomaterials, 2021
Graphite nanoplatelets (GNPs) as an oil nano additive has gained importance to enhance the lubrication properties of renewable lubricants, such as vegetable oils. Using appropriately processed GNPs is necessary to gain the required tribological advantage.

Friction Modelling in Boundary Lubrication Considering the Effect of MoDTC and ZDDP in Engine Oils

Tribology Online, 2011
A predictive friction model has been developed in boundary lubrication conditions to understand the sensitivity of the model to molybdenum dithiocarbamate (MoDTC), a friction modifying additive and zinc dialkyldithiophosphate (ZDDP), an antiwear additive

Conductances between confined rough walls [PDF]

, 2004
Two- and three-dimensional creeping flows and diffusion transport through constricted and possibly rough surfaces are studied. Asymptotic expansions of conductances are derived as functions of the constriction local geometry.
