Hexagonal boron nitride, as a layered material with graphite-like structure, exhibits good mechanical, lubricating and oxidation resistance properties, is thus expected to become one of the top choices for green oil additives. However, its poor dispersibility in difficulties preparing spherical particles when constructing hexagonal nitride limit application. In this paper, nanoparticles are con...

This study relates to developing future alternative fuels and focuses on the effects of a fuel’s molecular structure its properties performance in advanced propulsion systems. The tribological various biomass-derived oxygenated fuels, including butanol, pentanol, cyclopentanol, cyclopentanone, gasoline their blends with diesel, was investigated. Lubricity tests were conducted using high-frequen...
