Title: Diamond nanostructures with large surface area and method of producing the same

Abstract

A method for forming diamond nanostructures with large specific area can include forming porous diamond nanostructures by means of selectively etching sp2-bonded carbon and partially removing sp3-bonded carbon in nanocrystalline diamond (NCD) and ultrananocrystalline diamond (UNCD® diamond). The diamond nanostructures achieved from the disclosed method can include a long shaft surrounded by a school of barbs. The nanostructure can provide a significantly larger surface area than diamond without such a nanostructure and its fabrication provides relative ease of manufacture compared to traditional techniques.

n-Type diamond and method for producing same

Patent Anderson, Richard J [Oakland, CA]

A new n-type semiconducting diamond is disclosed, which is doped with n-type dopant atoms. Such diamond is advantageously formed by chemical vapor deposition from a source gas mixture comprising a carbon source compound for the diamond, and a volatile hot wire filament for the n-type impurity species, so that the n-type impurity atoms are doped in the diamond during its formation. A corresponding chemical vapor deposition method of forming the n-type semiconducting diamond is disclosed. The n-type semiconducting diamond of the invention may be usefully employed in the formation of diamond-based transistor devices comprising pn diamond junctions, and in othermore » microelectronic device applications. « less

Method for producing high surface area chromia materials for catalysis

Patent Gash, Alexander E [Brentwood, CA]; Satcher, Joe [Patterson, CA]; Tillotson, Thomas [Tracy, CA]; ...

Nanostructured chromium(III)-oxide-based materials using sol-gel processing and a synthetic route for producing such materials are disclosed herein. Monolithic aerogels and xerogels having surface areas between 150 m.sup.2/g and 520 m.sup.2/g have been produced. The synthetic method employs the use of stable and inexpensive hydrated-chromium(III) inorganic salts and common solvents such as water, ethanol, methanol, 1-propanol, t-butanol, 2-ethoxy ethanol, and ethylene glycol, DMSO, and dimethyl formamide. The synthesis involves the dissolution of the metal salt in a solvent followed by an addition of a proton scavenger, such as an epoxide, which induces gel formation in a timely manner.
