this paper addresses the annealing temperature effect on nanostructure and phase transition of copper oxide thin films, deposited by pvd method on glass substrate (at 110 nm thickness) and post annealed at different temperatures (200-400°c) with a flow of 1 cm3s-1 oxygen. the x-ray diffraction (xrd) was employed for crystallographic and phase analyses, while atomic force microscopy (afm) was us...

Graphene oxide-wrapped amorphous copper vanadium oxide is fabricated through a template-engaged redox reaction followed by vacuum dehydration. This material exhibits high reversible capacity, excellent rate capability, and out standing high-rate cyclability. The outstanding performance is attributed to the fast capacitive charge storage and the in situ formed copper with enhanced electrical con...

introduction: iiron oxide nanoparticles (io np) have an increasing number of biomedical applications. to date, the potential cytotoxicity of these particles remains an issue of debate. little is known about the cellular interaction or toxic effects of io np on differentiation of stem cells. the aim of the present study was to investigate the possible toxic role of different doses of io np in di...

The objective of the work reported is to study the effect of wavelength and the material removal mechanisms of a laser process for removing copper oxide from copper. The removal of copper oxide is necessary in electronics device fabrication in order to improve the surface wetability and so achieve a good quality solder joint. Such a laser cleaning process could be incorporated into an existing ...

The use of colored semiconductor oxide like copper (II) oxide and nickel (II) oxide for photocatalytic bleaching of rose bengal was investigated in detail. In order to harness the solar energy, the effective wavelength of the photocatalyst is to be expanded into the visible region and that increases the rate of photocatalytic bleaching of the dye. Progress of the reaction was observed spect...

Pristine monocrystalline graphene is claimed to be the strongest material known with remarkable mechanical and electrical properties. However, graphene made with scalable fabrication techniques is polycrystalline and contains inherent nanoscale line and point defects--grain boundaries and grain-boundary triple junctions--that lead to significant statistical fluctuations in toughness and strengt...

We report the capacity of copper oxide-containing filters to reduce infectious titers of a panel of viruses spiked into culture media. Enveloped, nonenveloped, RNA, and DNA viruses were affected, suggesting the possibility of using copper oxide-containing devices to deactivate a wide spectrum of infectious viruses found in filterable suspensions.

Recent experiments indicate that static stripe-like charge order is generic to the hole-doped copper oxide superconductors and competes with superconductivity. Here we show that a similar type of charge order is present in La5/3Sr1/3CoO4, an insulating analogue of the copper oxide superconductors containing cobalt in place of copper. The stripe phase we have detected is accompanied by short-ran...

The steady, laminar, stagnation point flow of hybrid nanofluid past a nonlinearly stretching and shrinking sheet is studied. Hybrid regarded by disseminated two distinct nano-sized particles, silver (Ag) copper oxide (CuO) in pure water. Similarity technique was used for the transformation partial differential equations (PDEs) into an ordinary equation (ODEs). Obtained ODEs were solved using Ma...
