Abstract: Additive manufacturing compositions and methods for fabricating a conductive article with the same are provided. The additive manufacturing composition may include a 3D printable material, a plurality of porogens disposed in the 3D printable material, and a metal precursor disposed in the 3D printable material. The metal precursor may include a metal salt, a metal particle, or combinations thereof. The method may include forming a first layer of the article on a substrate, where the first layer includes the additive manufacturing composition, forming a second layer of the article adjacent the first layer, and binding the first layer with the second layer to fabricate the article. The method may also include plating a metal on the article to fabricate the conductive article.

Abstract: An electrochemical device suited to modifying a carbon dioxide concentration in an interior space includes a cathode chamber with an inlet which receives a feed gas containing carbon dioxide. A reduction catalyst layer in the cathode chamber reduces carbon dioxide in the gas to form an ionic carrier species. An anode chamber with an outlet outputs a gas comprising carbon dioxide. A solid electrolyte membrane spaces the anode chamber from the cathode chamber and transports the ionic carrier species between the cathode chamber and the anode chamber. The membrane includes an ionic liquid. An oxidation catalyst layer in the anode chamber oxidizes the ionic carrier species to form carbon dioxide. A voltage source provides a voltage difference across the membrane.

Abstract: A capacitive relative humidity sensor includes a first electrode and a second electrode, where at least the one of the electrodes is a water-permeable electrode. The electrodes act in conjunction with a water-sensitive hygroscopic dielectric material. The design enables low-cost and simple fabrication of fast-responding and stable relative humidity sensors using digital fabrication techniques.
