Abstract: A non-volatile magnetic memory device having one or more memory cells, each of the memory cells includes a magnetic switch including a C-shaped magnetic component and a write coil located proximate the magnetic component, the write coil coupled to receive a current sufficient to create a remnant magnetic polarity in the magnetic component, and a Hall sensor, positioned proximate the magnetic component, to detect the remnant magnetic polarity indicative of a stored data bit.

Abstract: The invention encompasses fabrication methods including the steps of preparing a silicon substrate, forming an amorphous III-V material layer on the silicon substrate, heating the amorphous III-V material layer, and epitaxially growing III-V material on the amorphous III-V material layer.

Abstract: The invention is directed, in part, to stable compositions of suspended carbon nanotubes, methods of making them, and uses thereof. The invention provides methods of producing high and low concentrations of highly dispersed carbon nanotubes suspended in a liquid. The carbon nanotube suspensions are of use in generating products with improved strength, weight, strength to weight ratio, electrical and thermal versatility, radiation shielding, capacitance, dielectric properties, selective ion flow, catalytic activity and biological applications. The invention provides for industrial processing of materials comprising carbon nanotubes such as, but not limited to, fibers, films, synthetic membranes, coatings, drug delivery systems, and molecular circuitry components.

Abstract: A method for fabricating of macroscopic two or three dimensionally ordered arrays of single wall nanotubes (SWNTs) comprising the following steps: chemically treating purified SWNTs using the sol gel process to add chemically reactive groups to either the tube ends or tube bodies in order to functionalize the SWNTs; suspending the functionalized SWNTs in an appropriate liquid medium such that a colloid is produced; treating the colloid with a chemical or heat to promote coupling of the individual functionalized SWNTs to each other; and heating the coupled SWNTs to evaporate any excess liquid so as to provide a final product comprising an array of covalently bound functionalized SWNTs.
