Boron nitride nanotubes were functionalized with microperoxidase-11 in aqueous media, showing improved catalytic performance due to a strong electron coupling between the active centre of microperoxidase-11 and boron nitride nanotubes.

To determine the non-bonded interaction between methyl benzoate and boron nitridenanotube, we focused on an armchair single-wall boron nitride nanotube (9,9) With length 5 angstroms.The geometry of molecules was optimized using B3LYP method with 6-31g* basis set. Also reactivityand stability of methyl benzoate and boron nitride nanotube (9,9) was checked. Then NBO, FREQ,...

High Energy Materials is a term that is used for explosives, propellants and pyrotechnics. Explosives are used for military applications. 5-Picrylamino-1,2,3,4-tetrazole(PAT) is an explosive substance. In this study the reactions of the 5-Picrylamino-1,2,3,4-tetrazole(PAT) with nanostructures of fullerene and boron nitride nano-cages in different conditions of temperature, with density function...

Near-field spectroscopy has been extensively applied recently to analyze collective optical properties of materials at the nanoscale. However, vibrations small molecules were only recognizable in close proximity a metallic resonator. We show that encapsulation boron nitride nanotubes (BNNT) enhances near-field vibrational spectra C$_{60}$ fullerene, reaching sensitivity limit few hundred molecu...

Graphene-boron nitride monolayer heterostructures contain adjacent electrically active and insulating regions in a continuous, single-atom thick layer. To date structures were grown at low pressure, resulting in irregular shapes and edge direction, so studies of the graphene-boron nitride interface were restricted to the microscopy of nanodomains. Here we report templated growth of single cryst...

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...

This Research Article reports on the enhancement of the thermal transport properties of nanocomposite materials containing hexagonal boron nitride in poly(vinyl alcohol) through room-temperature atmospheric pressure direct-current microplasma processing. Results show that the microplasma treatment leads to exfoliation of the hexagonal boron nitride in isopropyl alcohol, reducing the number of s...

The neutron collision cross-section is important in neutron use for a specific job, such as neutron therapy or even in nuclear reactors. In calculating computational codes such as MCNP, only information from the neutron-to-mass collision information contained in the computational code library is used, in the case of nanoscale particles in contrast to the mass of materials and / or particulate m...

We report results from cathodoluminescence spectroscopy of boron nitride films grown on Si(100) substrates by ion-source-assisted magnetron sputtering of a hexagonal BN target. Three main peaks are observed in the near-band-gap region for hexagonal boron nitride films at energies of 4.90,5.31, and 5.50 eV We also report deep-level emission spectra of predominantly cubic boron nitride films whic...
