A simple electrochemical deposition was developed to synthesize the cuprous oxide (Cu(2)O) octahedra on aluminum foils. The average edge length of the octahedra is about 300 nm. The chemical composition of the octahedra was determined using energy dispersive X-ray spectroscopy and electron energy-loss spectroscopy. The microstructure of the octahedra was investigated using transmission electron...

There is currently an increased consumption of vegetables within the local urban community. However, contamination of these vegetables with heavy metals poses a potential health hazard. Consequently, the potential contamination problem due to the effect of levels of some heavy metals (Fe, Mg, Zn, Mn, Cu and Cr) in soils and vegetables irrigated with drainage urban grey waste water were investig...

The study aims to evaluate the removal of sulfur content from Iraqi light naphtha produced in Al-Dora refinery by adsorption desulfurization DS technique using modified activated carbon MAC loaded with nickel Ni and copper Cu as single binary metals. experiments were carried a batch unit various operating parameters; dosage, agitation speed, contact time 300 min at constant initial concentratio...

Plastic deformation behavior of Cu/Ni/W metallic multilayers with individual layer thickness ranging from 5 nm to 300 nm is investigated by nanoindentation testing. The experimental results reveal that the composite still exhibits indentation-induced plastic deformation instability and the loss of strain hardening ability at the nanometer scale even if the composite contains two kinds of layer ...

A simple hydrothermal redox reaction between microcrystalline CuOHCl and pyrrole leads to the isolation of striking nanostructures formed by polypyrrole-coated copper nanocables. These multicomponent cables that feature single-crystalline face-centered cubic Cu cores (ca. 300 nm wide and up to 200 μm long) are smoothly coated by conducting polypyrrole, which in addition to its functionality, of...

BACKGROUND Bilastine is a novel nonsedative H(1)-receptor antagonist, which may be used for the symptomatic treatment of chronic idiopathic urticaria (CU). The aim of this study was to compare the clinical efficacy and safety of bilastine 20 mg vs levocetirizine 5 mg and placebo in CU patients with moderate-to-severe symptoms. METHODS Overall 525 male and female subjects aged 18-70 years were...

Fifty weanling crossbred pigs averaging 6.2 kg of initial BW and 21 d of age were used in a 5-wk experiment to evaluate lower dietary concentrations of an organic source of Zn as a Zn-polysaccharide (Zn-PS) compared with 2,000 ppm of inorganic Zn as ZnO, with growth performance, plasma concentrations of Zn and Cu, and Zn and Cu balance as the criteria. The pigs were fed individually in metaboli...

Two cu-galactosidase (a-o-galactoside galactohydrolase, EC 3.2.1.22) isozymes have been highly purified from human placental tissue. Both isozymes appeared to be homogeneous based upon disc gel electrophoresis. Both were bound by concanavalin A-Sepharose and stained positively with the periodic acid-Schiff stain indicating that each contained carbohydrate. The A isozyme had a molecular weight o...

The paper focuses on the strength and toughness of joints produced by transient liquid phase (TLP) bonding in the Cu–Sn system. It is motivated by potential applications of TLP bonding in attachment of high-temperature wide bandgap devices to ceramic substrates. Model test specimens suitable for mechanical testing are developed, utilizing substrates of oxide dispersion strengthened copper. Thre...

The precipitation behavior and mechanical properties for conventionally solidified Al-2.0wt.%Cu-2.0wt.%Mn alloy were studied. supersaturated aluminum-based solid solution, CuAl2, Al6Mn Al20Cu2Mn3 phases of solidification origin identified after casting. high temperature ageing as-cast samples (T5 treatment) in a range 300–350 °C led to the formation metastable θ′ phase equiaxed precipitates qua...
