The effect of agricultural practices on nitrate accumulation in soils of different farmland systems in the Jordan Valley (JV) is not yet documented. This study aims at quantifying nitrate concentrations in top-soil and investigating its spatial distribution in the JV in order to help developing a nitrogen management plan for the JV. Results showed that nitrate concentrations range from 88.2 to ...

Paraffin sections were deparaffinized and hydrated to distilled water, then placed in 20% silver nitrate and kept in 60°C for 15 minutes, then rinsed in distilled water. Then sections were treated with formalin solution containing ammoniacal silver solution for about 15 min, followed by rinsing and placing tissue in sodium thiosulfate solution for 2 minutes and washing in tap water. The section...

Conjugate-base anions are ubiquitous in aqueous solution. Understanding the hydration of these anions at the molecular level represents a long-standing goal in chemistry. A molecular-level perspective on ion hydration is also important for understanding the surface speciation and reactivity of aerosols, which are a central component of atmospheric and oceanic chemical cycles. In this Account, a...

Copper nitrate in methanol solution cleaves the N-C(methanol) bond when reacted with 3-methyl-5-phenyl-pyrazole-1-methanol to yield the centrosymmetric dinuclear title compound, [Cu(2)(CH(3)O)(2)(NO(3))(2)(C(10)H(10)N(2))(4)], in which the Cu(II) atom is linked to a nitrate ion, two methano-late ions and two pyrazole ligands in a distorted square-pyramidal environment. The O atom of the nitrate...

various concentrations of copper are embedded into silica matrix to xerogel form using copper source - cu(no3)2∙3h2o. the xerogel samples are prepared by hydrolysis and condensation of tetraethyl orthosilicate (teos) by the sol-gel method  and with determination of new molar ratio of components h2o/teos to be 6.2. in this investigation, the necessary amount of trihydrated copper nitrate is adde...

The title compound, [Cu(NO(3))(C(18)H(15)P)(3)]·CH(3)OH, is a methanol solvate derivative of nitratotris(triphenyl-phos-phine)copper(I). The complex crystallizes with three triphenyl-phosphine ligands coordinated to the copper centre, with an O-H⋯O hydrogen bond observed between the nitrate ligand and the methanol solvent mol-ecule. The coordination around the Cu(I) centre is distorted tetrahed...

The aim of this research was to assess the treatment efficiencies for gully pot liquor of experimental vertical-flow constructed wetland filters containing Phragmites australis (Cav.) Trin. ex Steud. (common reed) and filter media of different adsorption capacities. Six out of 12 filters received inflow water spiked with metals. For 2 years, hydrated nickel and copper nitrate were added to siev...

Metal oxide nanoparticles supported on graphene exhibit high catalytic activity for oxidation, reduction and coupling reactions. Here we show that pyrolysis at 900 °C under inert atmosphere of copper(II) nitrate embedded in chitosan films affords 1.1.1 facet-oriented copper nanoplatelets supported on few-layered graphene. Oriented (1.1.1) copper nanoplatelets on graphene undergo spontaneous oxi...
