Nanoenergetic materials: boron nanoparticles from the pyrolysis of decaborane and their functionalisation.

High-pressure high-temperature synthesis and structure of α-tetragonal boron.

Microcrystals of α-tetragonal (α-t) boron with unit cell parameters a=9.05077(6) and c=5.13409(6) Å and measured density 2.16-2.22 g cm-3 were obtained by pyrolysis of decaborane B10H14 at pressures of 8-9 GPa and temperatures of 1100-1600 ○C. The crystal structure is in good agreement with the model proposed by Hoard et al (1958 J. Am. Chem. Soc.80 4507). However, compared to the original mode...

Deposition of Boron-Containing Films From Decaborane

Syntheses of Boron Nitride Nanotubes from Borazine and Decaborane Molecular Precursors by Catalytic Chemical Vapor Deposition with a Floating Nickel Catalyst

Multiand double-walled boron nitride nanotubes (BNNTs) have been synthesized with the aid of a floating nickel catalyst via the catalytic chemical vapor deposition (CCVD) of either the amineborane borazine (B3N3H6) or the polyhedral-borane decaborane (B10H14) molecular precursors in ammonia atmospheres. Both sets of BNNTs were crystalline with highly ordered structures. The BNNTs grown at 1200 ...

MATERIALS CHEMISTRY COMMUNICATION Nitrogen-containing carbon nanotubes

could be prepared by employing appropriate precursor molecules. Nanotubes containing both boron and nitrogen have Carbon nanotubes containing small amounts of nitrogen are been grown in the electric arc discharge between graphite produced by the pyrolysis of aza-aromatics such as pyridine, cathodes and graphite anodes filled with boron in a nitrogen methylpyrimidine and triazine over cobalt nan...

Investigation of the effect of Argon flow on the morphology of B4C nanoparticles synthesized by the VLS method

In this paper, new various morphologies of boron carbide were successfully synthesized using carbon black, activated carbon and boron oxide precursors as well as using cobalt nanoparticles as catalysts. Almost the whole morphology of synthesized boron carbide are consisted of smooth nanowires and nanobelts. With decreasing the carbon black particles size from 29 nm to 13 nm (29, 23, 17 and 13),...
