Synthesis of WO3 nanoparticles by arc discharge method

Tungsten trioxide nanoparticles have been prepared by arc discharge method in liquid medium. Dynamic Light scattering (DLS) results indicate that at arc current of 125A, the size of particles are about 30 nm and by increasing the arc current, the particles size

Nano

Two types of nano-cubes were produced by the electric arc discharge, the first composed only of silicon, and the second containing silicon, oxygen, carbon, sodium and fluorine. The nano-cubes were subjected to compression strength tests by the application of a load to the nano-cubes inserted between two polished sample stages with nano-level surface roughness.

Photocatalytic activity of ZnO nanoparticles prepared

ZnO nanostructures were synthesized through arc discharge of zinc electrodes in deionized (DI) water. X-ray diffraction (XRD) analysis of the prepared nanostructures indicates formation of crystalline ZnO of hexagonal lattice structures. Transmission electron microscopy (TEM) images illustrate rod-like as well as semi spherical ZnO nanoparticles with 15–20nbsp;nm diameter range, which were

Boron nitride nanotubes: synthesis and applications

2018/6/28Arc discharge method BNNT was experimentally found in arc discharge for the first time by Chopra et al. in 1995 []. A BN rod as a precursor for BNNT synthesis was inserted into a hollow tungsten anode electrode. Arc plasma generated between the cathode and

Laser Ablation

This site gives nanoscience and nanotechnology knowledges. In 1995, Smalley and co-workers produced carbon nanotubes using laser ablation technique [1]. In the laser ablation technique, a high power laser was used to vaporize carbon from a graphite target at high temperature.

Nanotechnology and Emerging Technologies News from

2019/4/3The rolling-up direction (rolling-up or chiral vector) of the graphene layers determines the electrical properties of the nanotubes. Chirality describes the angle of the nanotube's hexagonal carbon-atom lattice. Armchair nanotubes – so called because of the armchair-like shape of their edges – have identical chiral indices and are highly desired for their perfect conductivity.
