Abstract The thermal properties of Octadecane vary due to the addition copper oxide (CuO) nanoparticles. synthesis two nano‐enhanced phase change material (NEPCM) required implementation two‐step method, using as base and CuO nanoparticles at 2.5 5.0 wt%. experimental characterization determined specific heat capacity, conductivity NEPCMs solid phase, including enthalpy temperature. These resul...

a facile mechanochemical-based method for synthesis of copper oxide (cuo) nanoparticles is here by introduced. for this purpose, copper hydroxide powder was synthesized through a facile solution method (cuso4 + 2 na(oh) → cu(oh)2 + na2so4) after which milling of as-prepared cu(oh)2 precursor and nacl resulted in the mechanochemical dehydration of cu(oh)2 and dispersion of cuo nanoparticles into...

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Energy and exergy (EnE) efficiencies are considered the most important parameters to compare performance of various thermal systems. In this paper, an analysis was carried out for EnE a flat plate solar collector (FPSC) using four different kinds nanofluids as flowing mediums, namely, Al2O3/water, MgO/water, TiO2/water, CuO/water, compared with water medium (traditional base fluid). The made na...

Bahrain is a very small oil-exporting country in the Middle East with a fixed exchange rate against the US dollar and has no restricton capital flows. Because its economy evolves around the oil sector, its economy is thought to be vulnerable to oil price movements. It is feared that the recent oil price hike would feed from foreign assets to monetary base and money supply to inflation. Empirica...

The WSe(2) nanorods were synthesized via solid-state reaction method and characterized by X-ray diffractometer, TEM, and HRTEM. The results indicated the WSe(2) compounds had rod-like structures with diameters of 10-50 nm and lengths of 100-400 nm, and the growth process of WSe(2) nanorods was discussed on the basis of the experimental facts. The tribological properties of WSe(2) nanorods as ad...

We report here on the first study of the growth kinetics of high-yield, vertical CuO nanowires on silicon substrates produced by the process of thermal oxidation. The length of the CuO nanowires could be tuned from several to tens of micrometers by adjusting the oxidation temperature and time. The grown CuO nanowires were determined to be single-crystalline with different axial crystallographic...

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...
