Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability...

Abstract Friction and wear are ubiquitous, from nano-electro-mechanical systems in biomedicine to large-scale integrated electric propulsion aircraft carriers. Applications of nanomaterials as lubricating oil additives have achieved great advances, which significance control friction wear. This review focuses on the applications comprehensively compares their tribological characteristics additi...
