An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...

appropriate management of soil phosphorus (p) fertility in highly calcareous soils of iran as around the world should rely upon sound knowledge about the phosphorus reserve and its bioavailability. despite numerous reports on the positive effects of vesicular arbuscular mycorrhizae (vam) fungi on phosphorus uptake which is associated to ectomycorrhiza as a branch of two major branches of group ...

in this work, the effect of presence of the sodium tripolyphosphate (stpp), as an inorganic salt, on improving the performance of polyamide (pa) thin layer membranes has been studied. characterization analyses confirmed the presence of the salt on the whole surface structure of the thin layer. different salt loadings resulted in different fluxes and cu (ii) rejections. the thin layer containing...

Ab initio calculations reveal that all-metal antiaromatic molecules like Al4M4 (M = Li, Na and K) can be stabilized in half sandwich (Al4M4)Fe(CO)3 and full sandwich (Al4M4)2Ni complexes. The formation of the full sandwich complex [(Al4M4)2Ni] from its organometallic precursor depends on the stability of the organic-inorganic hybrid (C4H4)Ni(Al4Li4).

A highly selective femtomolar level sensing of inorganic arsenic(III) as arsenious acid has been accomplished in water medium and in living-systems (on pollen grains of Tecoma stans; Candida albicans cells (IMTECH No. 3018) and Peperomia pellucida stem section) using a non-toxic fluorescent probe of a Cu(II)-complex.

A facile synthesis of polymer-inorganic hybrid hollow mesoporous nanospheres was developed based on the entrapment of a dissolved polymer core template in the framework during the assembly process of the hybrid hollow nanospheres for efficient and size-selective enrichment of target peptides/proteins from complex biosamples.

A systematic description of polyhedra with varying degrees of regularity is illustrated with examples of chemical structures, mostly from different fields of Inorganic Chemistry. Also the geometrical relationships between different polyhedra are highlighted and their application to the analysis of complex structures is discussed.

Herein we report a method to functionalize in vitro grown insulin amyloid fibrils with various inorganic materials. The counterion of the positively charged amyloid fibril is exchanged with anions from various salts; subsequent addition of appropriate cations results in functionalization of the amyloid fibril. We demonstrate the formation of apatite and platinum complex structures ordered by th...

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.

Factors affecting candicidin synthesis and mycelial growth of Streptomyces griseus IMRU 3570 were studied. Inorganic phosphate was found to inhibit candicidin synthesis but to stimulate mycelial growth. Zinc, iron, and magnesium ions stimulated candicidin synthesis at relatively high concentrations in a complex medium but not in a synthetic medium. No other factors studied, such as temperature,...
