Fabrication and Characterization of Copper Nanowires: An Overview
Abstract: Copper (Cu) is one of the most important metals in modern electronic technology. Keeping in view its role in nanoelectronics, we have fabricated copper nanowires of diameters 100 and 200 nm using Anodic Alumina and polymer membranes as templates. Template-based growth of copper nanowires has been realized using conventional electro deposition technique in an electrochemical cell designed in our laboratory. Fabrication of copper nanowires is one of the most important …

Crystal structure investigation of La doped BiFeO3 multiferroics by Rietveld analysis
Abstract: AbstractPolycrystalline materials with composition Bi0.8La0.2FeO3 multiferroics were prepared through solid state reaction method. The room temper ature XRD confirmed the very well synthesis of the sample without any trace of any impurity phase. The Rietveld analysis of the XRD pattern manifest the interesting evident of devising the structural phase not exactly Rhombohedral (R3c) but instead it exhibits a combination of 90% rhombohedral(R3c) and 10% α phase of BiFeO3 Triclinic (P1). …

Synthesis of Metallic Copper Nanoflowers, Nanocrystals and Nanorods using Electrodeposition and Hydrothermal Techniques
Abstract: Copper nanoflowers and nanocrystals have been fabricated using two different techniques; electro-deposition of copper in polymer and anodic alumina templates (AAT) and Cetyltrimethyl-ammonium Bromide (CTAB)-assisted hydrothermal method. Nanorods of copper are produced by electrodeposition in 100 nm AAT. Scanning Electron Microscope (SEM) micrographs record some interesting morphologies of metallic copper nanoflowers and nanocrystals. Field Emission Scanning Electron Microscope (FESEM) has been used to determine morphology and chemical composition of polycrystalline …

Response of Magnetic Field by Conduction Electrons at Low Temperature in 2H-NbSe2
Abstract: AbstractHere, we have presented the magneto-resistance (MR) on polycrystalline and single crystal of2H-NbSe2. The obtained MR on single crystal shows anisotropic nature associated with smalllongitudinal MR i.e. 0 / in which H II direction of current flow compared totransverse MR i.e. 0 / in which H direction of current flow. This anisotropybehaviour is associated with the complex Fermi surface found from …

Crystallinity of commercial carbon fibers from X-ray diffraction (XRD) studies
Abstract: Sized carbon fibers have commercial significance. Such carbon fibers serves has excellent reinforcing material with the polymer resin filler matrix leading to the formation of carbon fiber reinforced composites (CFRCs). Polarized carbon fibers find applications in the realms of health, energy, environment, defence, catalysis and smart materials. For brevities sake, the focus of the current research paper is only on the structural characterization of carbon fibers using XRD. The structure …
