Abstract: A method for preparing an ammonium thiomolybdate-porous amorphous carbon composite superlubricity film is disclosed. First, a porous amorphous carbon film is prepared by an anode layer ion source assisted plasma chemical vapor deposition method and a reactive magnetron sputtering method on a substrate. The porous amorphous carbon film is then impregnated in an ammonium thiomolybdate solution, so that the ammonium thiomolybdate is adsorbed on the porous amorphous carbon film, and the impregnated porous amorphous carbon film is air dried.

Abstract: A method for preparing a super-lubricative multi-layer composite fullerene-like carbon layer/graphene-like boron nitride thin film is provided. A substrate is ultrasonically cleaned in absolute ethyl alcohol and acetone sequentially for 15 min. The substrate is cleaned by argon plasma bombardment for 15 min. A fullerene-like carbon layer A having an onion-like structure is prepared by high-vacuum medium-frequency magnetron sputtering for 30 s. A graphene-like boron nitride layer B is prepared by high-vacuum medium-frequency magnetron sputtering and coating device to sputter the elemental boron target for 30 s. Steps (3) and (4) are repeated 80 times to overlay the fullerene-like carbon layer A and the graphene-like boron nitride layer B in an alternate way. The super-lubricative multi-layer composite fullerene-like carbon layer/graphene-like boron nitride thin film has a large load capacity, and excellent wear resistance, high temperature resistance and super lubrication.

Abstract: This disclosure provides a method for concentrating a solution of a macromolecule that is retained on at least two semi-permeable membranes that have different molecular weight cutoffs (MWCOs), the method comprising passing the solution through a hybrid configuration of said semi-permeable membranes staged in series in a single pass tangential flow filtration (SPTFF) apparatus. The method is applicable to the efficient concentration of biological macromolecules such as proteins, antibodies and nucleic acids.
