In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...

Design: The Age-Related Eye Disease Study, an 11center double-masked clinical trial, enrolled participants in an AMD trial if they had extensive small drusen, intermediate drusen, large drusen, noncentral geographic atrophy, or pigment abnormalities in 1 or both eyes, or advanced AMD or vision loss due to AMD in 1 eye. At least 1 eye had best-corrected visual acuity of 20/32 or better. Particip...

This work presents positive experimental evidence for the hole traps in ZnO nanorods, which take part in recombination and change the thermal quenching of Cu-related green emission. The evolution of Cu impurity upon annealing, as well as the formation of Cu-related shallow donors with an energy level of ∼0.11 eV are also indicated by temperature-dependent photoluminescence.

The heterogeneity and local distribution of elements are established as a result the study nonferrous metals composition domestic wastes processing concentrate containing 20–40% copper, 40–50% brass, 20–28% zinc up to 1% aluminium. Metals mainly concentrated in granules three types: zinc-based, copper-based copper–zinc alloy, i.e., brass. phase these granule types their structure determined. Zi...

Materials and methods: Ninety-six crossbred pigs 17 to 20 days old were randomly assigned to six experimental diets. A nonmedicated basal diet was supplemented with carbadox (55.12 g per tonne), copper sulfate (192.40 g copper per tonne), zinc oxide (2712.68 g zinc per tonne), or the probiotic feed additive BioPlus2B (Chr Hansen Inc, Milwaukee, Wisconsin; 1.1 × 106 or 1.3 × 106 spores per gram ...

The development of active catalysts for carbon dioxide (CO2) hydrogenation to methanol is intimately related the creation effective metal-oxide interfaces. In this work, we investigated how order addition copper and zinc on zirconia influences catalytic properties, activity selectivity toward methanol. Regarding conversion production, which promoter (zinc) was atomically deposited after impregn...

Nanostructured zinc oxide is intensively studied semiconductor showing photocatalytical activity. There are several precursors which can be used for the preparation of nanostructured zinc oxide like zinc acetate, zinc sulphate and many others. Zinc chloride is another compound which can serve as a zinc source for zinc oxide preparation. Nowadays the environmental aspects connected to applicatio...
