    Enhanced load bearing by polymer solutions lubricating external near-contact of sliding cylinders

    A small fixed cylinder attached to a load cell almost touches a larger, rotating cylinder (axes parallel). Newtonian liquids in the gap give reasonable loads, but viscoelastic liquids give markedly enhanced lo...
