Leverage about synthesis and dispersion with cuo nanoparticle in oil lubricating

The challenge for nanotechnology application in automotive lubrication is the difficulty in dispersing the nanoparticles in lubricating oils. Some factors have a direct influence on the dispersion of particles, such as size and shape, which are controlled by the chosen synthesis method. In addition,...
