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.

The present disclosure provides a filter for removing contaminants from a liquid or gaseous medium including a woven or nonwoven sheet of entangled carbon nanotubes. The present disclosure also provides a method for reducing the concentration of contaminants in a liquid or gaseous medium by contacting the liquid or gaseous medium with the filter.

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.

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.

A heat collector () is formed by at least one extruding step for reducing machining steps, and is assembled to a separately formed mounting frame () which may be stamped and formed or molded. The heat collector has flanges () which bear against retaining tabs () formed on the mounting frame, and may be held by solder, glue, or mechanical means. The heat collector may receive a heat dissipator (), or may be formed as a heat sink () such as a pin-fin type heat sink. The mounting frame can be fixed to a printed circuit board or the like having a component such as a central processing unit which contacts the collector in order to cool the unit.

In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages extending through a carbon plate, pressure chambers on one side of a carbon plate, flow-through passages on the other side of the same plate and ink supply passages, and a piezoelectric plate is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive. The piezoelectric plate may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate. An orifice plate may have specially profiled orifice openings to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate having orifice passages supplying ink from the pressure chambers to the orifices. Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate and, to assure grounding of the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate. Moreover, since the carbon plate is porous, it can provide a communication path between a vacuum source and an air-permeable, ink-impermeable layer on the ink passages to remove dissolved air from the ink in the passages. In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly.

In the embodiments described in the specification, a piezoelectric transducer has electrodes to the piezoelectric layer with an adhesive bonding agent under pressure applied hydraulically so as to be distributed uniformly throughout the surface of the piezoelectric layer. In one embodiment the dielectric film also carries conductor arrays for connecting the electrodes to remote driver chips at locations spaced from the surface of the piezoelectric layer.
