1. A system, comprising:
a foam and/or bubble-containing liquid comprising bubbles; and
an article at least partially submerged within the foam and/or bubble-containing liquid, wherein:
the article comprises a porous wall portion, the porous wall portion comprising at least one submerged pore establishing a gaseous pathway from an external surface of the article, through the porous wall portion of the article, and to an internal gas passageway of the article, the at least one submerged pore configured to restrict the transport of a liquid of the foam and/or bubble-containing liquid through the porous wall portion,
the external surface of the article is non-wetting with respect to the liquid, and
the external surface of the article comprises milliscale, microscale, and/or nanoscale protrusions that are configured to break liquid/gas interfaces of the bubbles of the foam and/or bubble-containing liquid such that gas within the bubbles is transported from the bubbles, through the porous wall portion of the article, and into the internal gas passageway of the article.
