Purification of Yard-Glass Shaped Boron Nitride Nanotubes

An efficient method for purification of Yard-Glass Shaped Boron Nitride NanoTubes (YG-BNNTs) fabricated via a Chemical Vapour Reaction (CVR) route has been developed. Impurities including carbon, Boron Nitride (BN), and Fe species in the pristine YG-BNNT sample are removed by a combined physical and chemical procedure which involv<e...

Microwave Synthesis of Boron Nitride Nanostructures

One dimensional boron nitride nanostructures promise many interesting applications in biomedical, semiconductor and hydrogen storage and other fields. We have synthesized Boron Nitride in various nanoforms by a high temperature solid state reaction between boric acid and urea in a commercial microwave furnace. The formation of boron nitride was established from the binding energies for boron an...

Theoretical comparison of thermodynamic parameters, NMR analysis, electronic properties of Boron Nitride and Aluminum Nitride nanotubes

In this research, geometrical structures of armchair single walled boron nitride nanotube (SWBNNT) and armchair single walled aluminum nitride nanotube (SWAlNNT) were optimized by Density Functional Theory (DFT) in the gas phase, both having the same length of 5 angstrom and n=9, m=9. B3LYP/6-31G* level of theory have been used to determine and compare electronic properties, n...

Structure of boron nitride nanotubules

We have used high-resolution transmission electron microscopy to resolve the @0001# projected basal plane structure and chirality relationships in boron nitride nanotubes. Evidence for tube growth along both ^101̄0& and ^112̄0& is found. Our results suggest that the ^112̄0& ~armchair! tubes form first. Subsequent growth can take the form of a ^101̄0& ~zig-zag! tube or additional armchair tubes. In ...
