摘要:
The invention concerns copper azide containing carbon nanotubes. The invention also concerns methods of producing such nanotubes by placing CuO nanoparticles within carbon nanotubes to produce CuO-containing carbon nanotubes, contacting CuO-containing carbon nanotubes with hydrogen to produce reduced nanotubes; and contacting the reduced nanotubes with hydrazoic acid to produce copper azide containing carbon nanotubes.

摘要:
Overall, the invention provides the chemistry for the compounds and for the processes to prepare compounds derived from 1,5-diazacyclooctanes. This makes available high density, high melting point, thermally stable small and medium ring nitrogen heterocycles that may also contain N-nitro, C-nitro or other functional groups. The compounds include cyclooctanes, bicyclo octanes, propellanes and functionalized derivatives of the above compounds. The preparations can include transannular cyclizations. The materials have several applications; e.g., the polynitro compounds are energetic materials.

摘要:
The present invention relates to methods for the preparation of a carbon nanotube from an amino-functionalized carbon nanotube via an amino oxidation reaction. The carbon nanotube includes nitrogen based functional groups that are covalently attached to lattice carbons of the carbon nanotube, directly or via a chemical linker. The synthetic methods of the present invention allow the nitrogen based functional groups to be attached selectively to one of two distinct regions of the carbon nanotube, and thus enable the synthesis of a carbon nanotube having nitrogen based functional groups substantially concentrated on the ends and/or the sidewall of the carbon nanotube.

The present invention relates to a carbon nanotube that contains nitrogen based functional groups (such as nitro, nitroso, N-oxide, oxime, hydroxylamine, diazo, azo, and azide) that are covalently attached to lattice carbons of the carbon nanotube, directly or via a chemical linker. The present invention also relates to methods for the preparation of the carbon nanotube from an amino-functionalized carbon nanotube via an amino oxidation reaction. The synthetic methods of the present invention allow the nitrogen based functional groups to be attached selectively to one of two distinct regions of the carbon nanotube, the ends or the sidewall, and thus enable the synthesis of a carbon nanotube having nitrogen based functional groups substantially concentrated on either the ends or the sidewall of the carbon nanotube.
