Facile Synthesis of Ternary Boron Carbonitride Nanotubes
In this study, a novel and facile approach for the synthesis of ternary boron carbonitride (B-C-N) nanotubes was reported. Growth occurred by heating simple starting materials of boron powder, zinc oxide powder, and ethanol absolute at 1150 degrees C under a mixture gas flow of nitrogen and hydrogen. As substrate, commercial stainless steel foil with a typical thickness of 0.05 mm played an add...
متن کاملCompilation on Synthesis, Characterization and Properties of Silicon and Boron Carbonitride Films
During the last years the interest in silicon and boron carbonitrides developed remarkably. This interest is mainly based on the extraordinary properties, expected from theoretical considerations. In this time significant improvements were made in the synthesis of silicon carbonitride SiCxNy and boron carbonitride BCxNy films by both physical and chemical methods. In the Si–C–N and B-C-N ternar...
متن کاملStructure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method
Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...
متن کاملMultiwall boron carbonitride/carbon nanotube junction and its rectification behavior.
In recent years, the ternary boron carbonitride (BCN) nanotubes have attracted increasing interests because of their unique electronic properties and potential technological applications. A prime advantage of the BCN nanotubes over their carbon counterparts is the relative simplicity in manipulating the electronic structures. Theoretical calculations have predicted that the band gap of BCN nano...
متن کاملLPCVD and characterization of boron-containing pyrocarbon materials
Pyrocarbon materials containing various amounts of boron have been prepared by LPCVD from BCl3–C3H8–H2 precursor mixtures. The growth rate is increased with respect to pure pyrocarbon deposition. By increasing BCl3 / (C3H8 + BCl3) ratio up to 85%, the incorporation of boron can reach 33 at.%. A small amount of boron (e.g. 8 at.%) highly enhances the anisotropy of pyrocarbon, as evidenced by opt...
