Abstract:

The present invention provides devices and methods for making nano structures such a nanoheater In one embodiment, the nanoheater element comprises a first reactive member and interlayer disposed in communication with at least a portion thereof. Preferably, contact between the first and second reactive members of the nanoheater element can yield at least one exothermic reaction. A nanoheater device of the invention can optionally comprise a substrate on which the first reactive member is positioned in combination with other components. The invention also provides a nanoheater system comprising a plurality of nanoheater elements. Exemplary nanoheater elements and systems can be used to perform a method of the invention in which heat is produced. Methods includes processes for fabricating nanostructures such as layered devices, nanorods and nanowires.

Abstract:

The present invention relates to methods of fabricating nanostructures using a replacement reaction. In a preferred embodiment, metal particles in an inert atmosphere undergo a replacement reaction to form a layer on the metal particle which is removed to form a high surface area nanostructure. A preferred embodiment includes the fabrication of heater elements, powders and heater assemblies using the nanostructures.

Abstract:

Metal flakes, an organic metal precursor, an organic solvent and either no binder, or a volatile or a thermally decomposable binder are combined to form a paste. The paste is deposited in a circuit pattern on a substrate and the circuit pattern is cured. While curing, the organic metal precursor decomposes to leave an electrically conductive path, and the printed circuit is thus formed. A precursor to an electrically conductive circuit material includes an organic metal precursor, metal microparticles, and an organic solvent. The method can be employed to form printed circuits, for a variety of electrical, electronic and sensing application, such as crack detection in ceramic, plastics, concrete, wood, fabric, leather, rubber or paper and composite materials.
