Abstract: Hollow fiber membranes, membrane contactors, and related production and use methods. The membranes include a substrate having a multiplicity of pores and a skin layer overlaying the porous substrate. The porous substrate includes a first semi-crystalline thermoplastic polyolefin (co)polymer resin and a nucleating agent in an amount effective to achieve nucleation. The skin layer includes a second semi-crystalline thermoplastic polyolefin (co)polymer resin derived by polymerizing at most 98 wt. % of 4-methyl-1-pentene monomer with at least 2 wt. % of linear or branched alpha olefin monomers. Preferably, the first thermoplastic polyolefin (co)polymer is different from the second thermoplastic polyolefin (co)polymer. The skin layer is less porous than the porous substrate and forms an outer surface of the hollow fiber with the porous substrate forming an inner surface. The hollow fibers are formed by co-extruding the porous substrate resin and the skin layer resin through an annular die.

Abstract: The present disclosure relates to a method for forming a transport mechanism for transporting at least one of a gas or a liquid. The method may comprise using a 3D printing operation to form the mechanism with an inlet and an outlet, and controlling the 3D printing operation to create the mechanism as an engineered surface structure formed in a layer-by-layer process. The method may further comprise controlling the 3D printing operation such that the engineered surface structure includes a plurality of cells propagating periodically in three dimensions, with non-intersecting, non-flat, continuously curving wall portions which form two non-intersecting domains, and where the wall portions have openings forming a plurality of flow paths extending in three orthogonal dimensions throughout from the inlet to the outlet, and such that the engineered cellular structure has wall portions having a mean curvature other than zero.
