title = "Boundary lubricants with exceptionally low friction coefficients based on 2D close-packed phosphatidylcholine liposomes",
abstract = "Liposomes of hydrogenated soy phosphatidylcholine (PC) lipids spontaneously self-assemble in close-packed layers on solid surfaces to form boundary lubricants that reduce the coefficient μ of sliding friction between them down to μ ≈ 10 -4 - 2 × 10 -5, at pressures up to ca. 12 MPa. This strikingly low value is attributed to hydration-lubrication by the PC headgroups exposed at the surfaces of the gel-phase vesicles.",
