Impact of molecular structure on the lubricant squeeze-out between curved surfaces with long range elasticity [PDF]
, 2006 The properties of butane (C4H10) lubricants confined between two approaching solids are investigated by a model that accounts for the curvature and elastic properties of the solid surfaces. We consider the linear n-butane and the branched iso-butane. For
