Nanoparticles as lubricant additives
Introduction Lubrication refers to interposition of solid, liquid or gaseous material in between surfaces of two material in contact to minimize friction and wear. All commercially available lubricants have additives in their formulation which enhance certain properties of oil like...
Three-dimensional subatomic scale AFM can measure friction
Atomic force microscopy (AFM) is an extremely sensitive technique that allows us to image materials and/or characterize their physical properties on the atomic scale by sensing the force above material surfaces using a precisely controlled tip. However, conventional AFM only...
