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.

Nanoheater elements, systems and methods of use thereof

Precursor-based methods for the production of metal-matrix composite (MMC) coatings on steel and aluminum substrates for improved wear, corrosion and oxidation resistance have been made. Wire and surface precursors are deposited on the substrate by controlled thermal processing using plasma-arc, laser and high-density infrared radiation. The temperature distribution during the formation for coating is controlled by a real tine adaptive control method. The wire precursors produced by continuous pressure infiltration of SiC or mullite fiber with aluminum were used. Steel substrates double-layer plated with binary metals including nickel and aluminum are also thermal-processed to in-situ produce compound such as nickel aluminide coatings.
