For the first time, ordered mesoporous ZnO nanoparticles have been synthesized by a template method. The electroplating after chemical plating method was creatively used to form copper film on the surface of the prepared ZnO, and then a CuO film-decorated ordered porous ZnO composite (CuO/ZnO) was obtained by a high-temperature oxidation method. In2O3 was loaded into the prepared CuO film-ZnO b...

Sr 2 CuO 3 and Ca 2 CuO 3 are considered to be model systems of strongly anisotropic, spin-1/2 Heisenberg antiferromagnets. We report on the basis of a band-structure analysis within the local density approximation and on the basis of available experimental data a careful analysis of model parameters for extended Hubbard and Heisenberg models. Both insulating compounds show half-filled nearly o...

The data presented in this article are related to the research article entitled "CuO photocathode-embedded semitransparent photoelectrochemical cell" (Patel et al., 2016) [1]. This article describes the growth of Cu oxides films using reactive sputtering and application of CuO photocathode in semitransparent photoelectrochemical cell (PEC). In this data article, physical, optical and electrical...

Abstract This study proposes a novel technology to enhance heat transfer by combining nanofluid and helical grooved tubes. The researchers used two-step method obtain stable modified CuO nanofluid. They then constructed an experimental setup investigate the single-phase of in tube, compared its performance traditional methods under varying volume fractions Reynolds numbers. results indicate tha...

Copper is an essential microelement that indispensable for plant growth and development. The use of copper oxide nanoparticles (CuO NPs) in industry agriculture has also increased because their beneficial properties. However, excess amounts CuO NPs may negatively affect the monocotyledonous species, primarily through generation reactive oxygen which results oxidative stress. Despite increasingl...

The global demand of the heating and cooling applications gives a larger potential to study thermal energy storage system. Phase change materials (PCM) that are used charge, store, discharge heat inferior in transfer characteristics. properties PCM can be improved by adding nanoparticles, changing orientation enclosure or both. Two-dimensional transient numerical analysis on effect Grashoff num...

objective(s):copper oxidenanoparticles have different industrial applications so it is inevitable that nanoparticulate products finally find their way into aquatic ecosystems. nevertheless there is little information available about their effects on some of edible fish. the present study aims to determine the acute toxicity and evaluate the effect of two sub-acute concentrations (50 and 70% 96 ...
