Ions serve as essential nutrients in higher plants and can also act as signaling molecules. Little is known about how plants sense changes in soil nutrient concentrations. Previous studies showed that T101-phosphorylated CHL1 is a high-affinity nitrate transporter, whereas T101-dephosphorylated CHL1 is a low-affinity transporter. In this study, analysis of an uptake- and sensing-decoupled mutan...

Ag thin films were successfully produced via a green chemistry method from silver nanoparticles (AgNPs) obtained reacting an extract of Pelargonium Zonale leaves with nitrate. The ions nitrate reduced to atoms by reducing stabilizer-capping compounds contained in the leaves. nucleate small clusters that grew into and finally, they formed homogeneous film on glass substrate. nanostructured chara...

Structural analysis of the nitrate complex of a thiophene-based azacryptand suggests that three nitrates are bridged with two bridgehead protons which play the topological role of two transition metal ions in a classical Werner type coordination complex bridging three anions.

Algae is an appropriate natural resource to augment the optimal use of undesired ions in water and wastewater. Increasing algal cells, consumption particular ions, including chloride, nitrate, phosphate, ammonium, provides a suitable way optimize treatment processes. Different species have capability survive extreme salinities by developing resistance against osmotic pressure saline water. The ...

Nitrite and nitrate are used as additives in the food industry to provide color and taste and to control undesirable gas and flavor production by anaerobic bacteria by virtue of their antimicrobial properties. The analytical method that has been widely used to determine nitrite and nitrate involves the use of toxic cadmium. In response to a request from the Nordic Committee on Food Analysis, a ...

We investigated the relevance of anions for the regulation of renin secretion from the kidneys. For this purpose we measured renin release from isolated rat kidneys that were perfused with medium containing either 120 mmol/l (normal) chloride or 95 mmol/l of isethionate, acetate, or nitrate anions in exchange for equimolar amounts of chloride. Lowering the extracellular chloride concentration b...

Nano-sized toroidal copper(II)-hydroxide/pyrazolate assemblies, lined by H-bond donors on the inside and hydrophobic on the outside, selectively extract sulfate from mixtures with nitrate or perchlorate. Tetrabutylammonium "lids" seal the "nano-jars" and render the encapsulated sulfate anion completely buried and inaccessible, so that it is not precipitated by Ba(2+) ions.

A method for the preconcentration and determination of Cr(III), Co(II), Cu(II), Fe(III) and Pb(II) ions by atomic absorption spectrometry has been described. The method was based the collection of metal-calmagite complexes on a soluble cellulose nitrate membrane filter. The detection of the solution was obtained by flame atomic absorption spectrometry (FAAS) after completely dissolving the memb...

In the title compound, [Cd(NO(3))(2)(C(24)H(20)N(2)O(2))], the Cd(II) ion is eight-coordinated by one ligand and two nitrate ions. There are C-H⋯O hydrogen bonds and C-H⋯π inter-actions and π-π inter-actions [centroid-centroid distance = 3.319 (1) Å] in the crystal structure.
