    摘要： A boron filled hybrid nanotube and a method for producing and rendering boron filled hybrid nanotubes suitable for applications are provided. A mixture of a boron containing nanowire producing compound and catalysts is prepared and ground for a predetermined time period. The ground mixture is subjected to a vapor deposition process including passing an inert gas over the ground mixture after adding a nanotube producing compound to the ground mixture or after passing a reactant gas on the ground mixture in a reactor at a configurable reaction temperature and a configurable reaction pressure for a configurable reaction time to produce the boron filled hybrid nanotubes with enhanced mechanical, thermal and electrical properties. Each boron filled hybrid nanotube includes one or more boron based nanowires embedded within one or more single walled or multi-walled nanotubes. The boron filled hybrid nanotubes are further purified and functionalized using acids, and/or bases, and/or surfactants.

    摘要： Composite structures having a reinforced material interjoined with a substrate and methods of creating a composite material interjoined with a substrate. In some embodiments the composite structure may be a line or a spot or formed by reinforced material interjoined with the substrate. The methods typically include disposing a precursor material comprising titanium diboride and/or titanium monoboride on at least a portion of the substrate and heating the precursor material and the at least a portion of the substrate in the presence of an oxidation preventative until at least a portion of the precursor material forms reinforced material interjoined with the substrate. The precursor material may be disposed on the substrate as a sheet or a tape or a slurry or a paste. Localized surface heating may be used to heat the precursor material. The reinforced material typically comprises a titanium boron compound, such as titanium monoboride, and preferably comprises β-titanium. The substrate is typically titanium-bearing, iron-bearing, or aluminum-bearing. A welding rod is provided as an embodiment. The welding rod includes a metal electrode and a precursor material is disposed adjacent at least a portion of the metal electrode. A material for use in forming a composite structure is provided. The material typically includes a precursor material that includes one or more materials selected from the following group: titanium diboride and titanium monoboride. The material also typically includes a flux.
