Boron Carbon Nitride Nanostructures from Salt Melts ...

A simple, high yield, chemical process is developed to fabricate layered h-BN nanosheets and BCNO nanoparticles with a diameter of ca. 5 nm at 700 °C. The use of the eutectic LiCl/KCl salt melt medium enhances the kinetics of the reaction between sodium borohydride and urea or guanidine as well as the dispersion of the nanoparticles in water.

A hexagonal boron nitride thin film is grown on a metal surface of a growth substrate and then annealed. The hexagonal boron nitride thin film is coated with a protective support layer and released from the metal surface. The boron nitride thin film together with the protective support layer can then be transferred to any of a variety of arbitrary substrates.

Boron Nitride - an overview | ScienceDirect Topics

Boron nitride (BN) is a chemical compound that is isoelectronic and isostructural to carbon with equal composition of boron and nitrogen atoms. The first synthesis of boron nitride was in 1842 by Balmain (1842) using molten boric acid and potassium cyanide; however, stabilizing the material to form powders was a challenge until recently (Anon, 1958). ...

Boron nitride - Wikipedia

Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.

Synthesis of hexagonal boron nitride - Wikipedia

Two dimensional hexagonal boron nitride (2D h-BN) is a material of comparable structure to graphene with potential applications in e.g. photonics., fuel cells and as a substrate for two-dimensional heterostructures. 2D h-BN is isostructural to graphene, but where graphene is conductive, 2D h-BN is a wide-gap insulator.

Covalent Surface Functionalization of Boron Nitride ...

The chemical inertness and poor wetting properties of boron nitride nanotubes (BNNTs) hindered their applications. In this work, BNNTs have been functionalized with aniline groups by reacting with diazonium salt and the graft content of aniline component was calculated as high as 71.4 wt.%. The chemical structure, composition, and morphology of functionalized BNNTs were carefully characterized ...
