  • Publication number: 20240151472
    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.

  • Patent number: 11885568
    Abstract: The present disclosure relates to a transport mechanism apparatus for transporting at least one of a gas or a fluid. The transport mechanism may have an inlet, an outlet and an engineered cellular structure forming a periodic nodal surface, which may include a triply periodic minimal surface (TPMS) structure. The structure is formed in a layer-by-layer three dimensional (3D) printing operation to include cells propagating in three dimensions, where the cells include non-intersecting, continuously curving wall portions having openings, and where the opening in the cells form a plurality of flow paths throughout the transport mechanism from the inlet to the outlet, and where portions of the cells form the inlet and the outlet.

  • Publication number: 20220193596
    Abstract: A composite material for gas capture including CO2 capture and capture of other gases. The composite material includes solid or liquid reactive material, filler material, and a gas-permeable polymer coating such that the reactive material forms micron-scale domains in the filler material.
