catena-Poly[[(l-me-thio-nine-κO)zinc]-μ3-(hydrogen phosphato)-κ(3) O:O':O''], [Zn{PO3(OH)}(C5H11NO2S)] n , a new one-dimensional homochiral zincophos-phate, was hydro-thermally synthesized using l-me-thio-nine as a structure-directing agent. The compound consists of a network of ZnO4 and (HO)PO3 tetra-hedra that form ladder-like chains of edge-fused Zn2P2O4 rings propagating parallel to [100]. ...

Zinc (Zn) and iron (Fe) deficiencies are well-documented public health issue and an important soil constraint to crop production. Generally, there is a close geographical overlap between soil deficiency and human deficiency of Zn and Fe, indicating a high requirement for increasing concentrations of micronutrients in food crops. Breeding new plant genotypes for high grain concentrations of Fe a...

High Zn and Cu fecal concentrations impact the environment. Zn and Cu reductions in feed have compromised swine performance. Substituting amino acid chelated (AAC) sources for traditionally employed inorganic salts (IM) may overcome environmental and swine performance problems. A preliminary study demonstrated less 65Zn was deposited in rat feces due to greater AAC absorption compared to IM (P ...

Three new inorganic-organic hybrid compounds based on Strandberg-type anions and Zn(ii)-H2biim/H2O subunits, namely {H4(H2biim)3}[Zn(H2biim)(H3biim)(H2O)(HP2Mo5O23)]2·3H2O (1), {H9(H2biim)7}[(μ-biim){(Zn(H2O)2)0.5(HP2Mo5O23)}2]·7H2O (2) and {H7(H2biim)7}[Zn(H2biim)(H2O)2(HP2Mo5O23)][H2P2Mo5O23]·8H2O (3) (H2biim = 2,2'-biimidazole), have been synthesized in aqueous solutions and characterized. T...

A simple method for the rapid identification of inorganic salts used as raw materials during food production has been established using energy dispersive X-ray fluorescence (EDXRF). Intensities of Na, Mg, P, S, Cl, K, Ca, Mn, Fe, Cu, Zn Kalpha peaks have been measured. The treatment and comparison of the respective intensities allowed a rapid identification of inorganic salts. Two different met...

Novel saponification-triggered gelation in an ester-based bis-salen Zn(II) complex (1) is described. Strategic structural modifications induced by NaOH in 1 tune the dipolar-/π-interactions leading to J-aggregation and the creation of an inorganic gel material (IGM), which has been established by photophysical, DFT and rheological studies.

Rouf, M. A. (Washington State University, Pullman). Spectrochemical analysis of inorganic elements in bacteria. J. Bacteriol. 88:1545-1549. 1964.-Quantitative spectrochemical analyses of inorganic elements in the vegetative cells of Escherichia coli, Sphaerotilus natans, Micrococcus roseus, Bacillus cereus, and the spores of B. cereus were made. The following elements were found to be present i...

The silica-based Fe(III)-protoporphyrin and Zn-tetraphenylporphyrin stationary phases were examined for the HPLC separation of anions. The retention of nine common inorganic anions as well as benzoate anion (BA) and its hydroxy analogues (HBA) was examined using tartrate, acetate, and succinate eluents. The retention factors of inorganic anions on the FeProP stationary phase were in the order C...

Zinc (Zn) deficiency is widespread throughout the world causing economic losses on a number of crops. Despite the fact that much information was generated during the last 20 years on Zn soil chemistry and its inorganic phase equilibrium, the mechanism controlling the amount of free Zn+2 present in the soil solution is not yet completely understood. This information is critical for the developme...

Newly synthesized Zn(II) and Cd(II)-based complexes show unique selectivity towards inorganic pyrophosphate (PPi) in 100% aqueous medium at pH = 7.4 and act as a "turn-on" and "turn-off" real-time assay, respectively, for the evaluation of the enzymatic activity of alkaline phosphatase.
