  • In this present investigation, the mechanical properties of industrial drawn copper wires have been studied by tensile tests. The effect of prior heat treatments at 500°C on the drawn wires behavior was the main goal of this investigation. We have found that the mechanical behavior of drawn wires depends strongly on those treatments. SEM observations of the wire cross section after tensile tests have shown that the mechanism of rupture was mainly controlled by the void formation.
  • Novel rose-like three-dimensional Sn(HPO{sub 4}){sub 2}.H{sub 2}O nanostructures self-assembled by tightly stacked nanopetals were successfully synthesized by a simple cetyltrimethylammonium bromide (CTAB)/water/cyclohexane/n-pentanol microemulsion system under solvothermal conditions for the first time. A series of compared experiments were carried out to investigate the factors that influence the morphology and size of the products. It was found that the molar ratio of water to CTAB and the concentration of SnCl{sub 4} aqueous solution play important roles in the formation of the rose-like nanostructures. A possible formation mechanism of rose-like nanostructures was proposed, which may be related to the crystal structure of Sn(HPO{submore » 4}){sub 2}.H{sub 2}O and the spherical micelles formed by the microemulsion. The electrochemical properties of Sn(HPO{sub 4}){sub 2}.H{sub 2}O were investigated through cyclic voltammetry (CV) measurements. X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and field-emission scanning electron microscope (FE-SEM) were used to characterize the products.« less
  • Highly uniform, porous {beta}-Co(OH){sub 2} nanostructures with an appearance reminding of certain spherical corals were synthesized via a facile, one-step hydrothermal route using ethanol-water mixtures as solvents. The rough surfaces of the nanostructures consist of numerous randomly distributed, interconnecting nanoflakes, resulting in a network-like structure with many cavities. The coral-like product has a high Brunauer-Emmet-Teller specific surface area of 163 m{sup 2}/g. The diameter of the coral-like {beta}-Co(OH){sub 2} nanostructures is adjustable from 800 nm to 2 {mu}m. The effects of the ethanol/water ratio, the Co{sup 2+} concentration, the hydrothermal temperature, and the reaction time on the formation of themore » coral-like structures were investigated. Cyclic voltammetry and galvanostatic charge-discharge tests show that the {beta}-Co(OH){sub 2} possesses excellent capacitive properties. This is mainly attributed to the high porosity, which allows a deep penetration by electrolytes. - Abstract: Coral-like {beta}-Co(OH){sub 2} nanostructures were synthesized via a facile ethanol-assisted hydrothermal route. Their high porosity facilitates a deep penetration by electrolytes and thus contributes to the excellent capacitive properties.« less
  • Graphical abstract: - Highlights: • Hierarchical CuO nanostructures were grown on Cu foil. • Monoclinic phase of CuO was grown. • XPS analysis revealed the presence of Cu(2p{sub 3/2}) and Cu(2p{sub 1/2}) on the surfaces. • Specific capacitance of 94 F/g was achieved for the CuO using cyclic voltammetry. • Impedance spectra show their pseudo capacitor applications. - Abstract: In this paper, we have investigated the electrochemical properties of hierarchical CuO nanostructures for pseudo-supercapacitor device applications. Moreover, the CuO nanostructures were formed on Cu substrate by in situ crystallization process. The as-grown CuO nanostructures were characterized using X-ray diffraction (XRD),more » Fourier transform-infra red spectroscopy (FT-IR), X-ray photoelectron spectroscopy and field emission-scanning electron microscope (FE-SEM) analysis. The XRD and FT-IR analysis confirm the formation of monoclinic CuO nanostructures. FE-SEM analysis shows the formation of leave like hierarchical structures of CuO with high uniformity and controlled density. The electrochemical analysis such as cyclic voltammetry and electrochemical impedance spectroscopy studies confirms the pseudo-capacitive behavior of the CuO nanostructures. Our experimental results suggest that CuO nanostructures will create promising applications of CuO toward pseudo-supercapacitors.« less
  • Highlights: • Vanadium oxides nanostructures were synthesized hydrothermally. • Reversible redox behavior with doping/dedoping process. • Doping/dedoping is easier for Li{sup +} to Na{sup +}. • Energy-related applications such as cathodes in lithium batteries. - Abstract: A facile and template-free one-pot strategy is applied to synthesize nanostructured vanadium oxide particles via a hydrothermal methodology. X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transforms infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) have been used to characterize the structure and morphology of the samples. The products are gradually changed from sheet-shaped VO{sub 2}(B) to rod-like V{sub 3}O{sub 7}·H{sub 2}O with decreasingmore » cyclohexanediol as both protective and reducing agent. The specific surface area of the VO{sub 2}(B) nanosheets and V{sub 3}O{sub 7}·H{sub 2}O nanorods was found to be 22 and 16 m{sup 2} g{sup −1}, respectively. Thin films of VO{sub 2}(B) and V{sub 3}O{sub 7}·H{sub 2}O deposited on ITO substrates were electrochemically characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The voltammograms show reversible redox behavior with doping/dedoping process corresponding to reversible cation intercalation/de-intercalation into the crystal lattice of the nanorods/nanosheets. This process is easier for the small Li{sup +} cation than larger ones Na{sup +}.« less
