    Abstract: Articles for emitting infrared energy comprising a nanostructured member including a plurality of nanotubes, the member being configured to emit infrared energy when an electrical current is applied; a reflecting member configured to direct at least a portion of the emitted infrared energy in a desired direction for heating a remotely-situated target, and optionally a spacer situated between the nanostructured member and the reflecting member to maintain a predetermined spacing there between, the predetermined spacing selected to minimize destructive interference between the infrared energy emitted by the nanostructured member and the infrared energy reflected by the reflecting member. In alternative embodiments, a carbonaceous member may be substituted for the nanostructured member.

    Abstract: An intumescent nanostructured material for thermal protection comprising a member including a plurality of nanostructured materials, and an intumescent material associated with the member and configured to react in the presence of a heat source to form a foam for thermally insulating the member from the heat source. The member may be a non-woven sheet, a woven sheet, a yarn, or a network, and may be configured to conduct thermal energy away from a heat source. A solution comprising a plurality of nanostructured materials, an intumescent material, and a solvent, wherein the solution has a viscosity suitable for coating or spraying onto a surface of a substrate. The solution may have a viscosity of about 3000 centipoise to about 6000 centipoise, and possibly less than about 1000 centipoise. The solution, when dried on the substrate, may form a thermally-protective coating on the substrate.

    Abstract: The present disclosure provides a method for purifying nanostructured material comprising carbon nanotubes, metal impurities and amorphous carbon impurities. The method generally includes oxidizing the unpurified nanostructured material to remove the amorphous carbon and thereby exposing the metal impurities and subsequently contacting the nanostructured material with carbon monoxide to volatilize the metal impurities and thereby substantially remove them from the nanostructured material.
