  • Patent number: 11850536
    Abstract: Described herein are methods for transporting and/or harvesting gas from bubbles, as well as associated articles and systems. In some embodiments, transporting and/or harvesting the gas from the bubbles can reduce or prevent the amount of foam that is present within a system. According to certain embodiments, a conduit comprising a porous wall portion can be at least partially submerged into a foam and/or a bubble-containing liquid. The porous wall portion of the conduit can be configured and/or arranged, according to certain embodiments, such that the porous wall portion provides a fluidic pathway through which gas from the bubbles within the liquid may be channeled to a gaseous environment in the interior portion of the conduit. The gas may be transported, according to certain embodiments, along the interior portion of the conduit into an external gaseous environment and/or harvested from the interior portion of the conduit.

  • Publication number: 20230149834
    Abstract: Foam mitigation using a variety of articles, systems, and methods is generally described. According to certain embodiments, surfaces with certain wetting properties can be used to reduce or eliminate the formation of foam from bubble-containing liquids. In some embodiments, a surface with certain wetting properties is configured and/or arranged within bubble-containing liquids such that the surface provides a gaseous fluidic pathway through which gas from the bubbles within the liquid may be channeled to a gaseous environment outside the liquid.
