Resumen
The adduct formation of iron(III) chlorophyll a with phosphines or phosphites has been studied by spectroscopic methods. The red-shift in the Soret and Q bands caused by the axial coordination of phosphine or phosphite to iron(III) chlorophyll a is an evidence for the autoreduction of the central iron(III) ion. The 31P{1H} NMR spectrum of bis-adducts measured in the presence of excess phosphine or phosphite ligands gave a single peak in the down field range compared to that of the corresponding free ligand. The ESR and X-ray photoelectron spectra have revealed that the central iron atom of the

Resumen
Two new uranyl compounds were hydrothermally synthesized employing piperazine as an organic templating agent. The piperazine was protonated in-situ by phosphorous acid, forming the piperazinium dication featured in these compounds. The two new structures presented here are a uranyl phosphite 2D sheet and a 3D uranyl mixed phosphite–phosphate network with cation occupied channels. Both included strong hydrogen bonding from the piperazinium cation to the uranyl phosphite or mixed phosphite–phosphate network. These two structures can be reliably formed through careful control of pH of the startin

Resumen
The influence of phosphite (H2PO3–) on the response of Saccharomyces cerevisiae to orthophosphate (HPO42–; Pi) starvation was assessed. Phosphate-repressible acid phosphatase (rAPase) derepression and cell development were abolished when phosphate-sufficient (+Pi) yeast were subcultured into phosphate-deficient (–Pi) media containing 0.1 mM phosphite. By contrast, treatment with 0.1 mM phosphite exerted no influence on rAPase activity or growth of +Pi cells. 31P NMR spectroscopy revealed that phosphite is assimilated and concentrated by yeast cultured with 0.1 mM phosphite, and that the levels

Resumen
Tomato and pepper plants were grown hydroponically in a greenhouse using phosphate or technical and commercial formulations of phosphite as sources of phosphorus nutrition to determine the effects on plant development and susceptibility to Phytophthora root and crown rot. Phosphite-treated tomato and pepper plants were deficient of phosphate and developed phosphorus-deficiency symptoms. Growth of plants (leaf area and leaf, stem, and root dry weights) that were fertilized with phosphite was significantly (P < 0.05) reduced compared with phosphate-fertilized plants.

Resumen
ABSTRACT Although used as an additional nutritional source of phosphorus in agriculture, little is known about the effects of phosphites on plants. In order to evaluate the influence of phosphite and phosphate on the accumulation and translocation of phosphorus and cationic nutrients, in common bean, three experiments were conducted. In the first experiment, five concentrations (0.5 mg L-1, 10 mg L-1, 20 mg L-1, 30 mg L-1 and 60 mg L-1) were studied in a nutrient solution combined with two forms of phosphorus [phosphate (Pi) and phosphite (Phi)].

Resumen
The soil borne plant pathogen Phytophthora cinnamomi has irreversibly altered the make-up and diversity of the plant communities found in Australia. Recently, the fungicide phosphite has been used to effectively reduce the impact of this pathogen in natural plant communities. However, little is known (a) about how rapidly phosphite is diluted in the tissues of rapidly growing plants and (b) how soil and plant phosphate levels interact with phosphite and its ability to induce host-resistant responses when challenged by P. cinnamomi.

La catalyse organométallique est une méthode de choix pour la synthèse de composés chiraux. Afin d'atteindre une selectivité et efficacité élevées en catalyse asymétrique, plusieurs paramètres réactionnels doivent être optimisés, parmi lesquels le choix et la structure du ligand sont sans doute les points les plus importants. Nous avons développé deux familles de ligands bidentates de type phosphine-phosphite et phosphine-carbène N-hétérocyclique. Ces deux séries de ligands possèdent une caractéristique structurale commune, à savoir un centre asymétrique adjacent à la phosphine. Cette proximit

Resumen
Phosphorus (P) has long been acknowledged as a vital nutrient for living organisms and is a key factor responsible for the fresh water eutrophication. Our understanding of the phosphorus cycle has been limited by: (1) the common assumption that all P in the environment occurs primarily as phosphates and (2) by the limited analytical methods available to identify P speciation. In an attempt to understand the distribution and chemistry of phosphorus within a freshwater system we must be able to identify individual P species. To this end, we used a coupled High Performance Liquid Chromatograph

Abstract This study examines the formation and consequences of delta ferrite (Fe₃P) in heat-treated bolts made from SAE10B30 microalloyed steel. The research demonstrates that when phosphated steel undergoes quenching and tempering in neutral or reducing atmospheres without proper cleaning, residual phosphate coating leads to the formation of delta ferrite—a brittle tetragonal phase with high hardness (approximately 450 HV) but poor toughness. Through comparative analysis of phosphate-treated and phosphate-free specimens heat-treated to 43-44 HRC, the authors identify that delta ferrite promot

Resumen
Abstract Alternate immersion cyclic exposure of prime coated and scribed steel sheet resulted in lifting of the coating at the edges of the scribe. A thick oxide corrosion product film grew in the scribe and under the adjacent coating. Continuous immersion did not produce thick oxide films or lifting of the coating. A phosphate pretreatment limited growth of the oxide to an area within the scribe and prevented attack at the coating/metal interface in cyclic exposures. Polarization resistance, measured during the immersion segment of the cycle, was higher for phosphated specimens, reflecting th

Resumen
Abstract More than 95% of the world demand for phosphoric acid is met by the wet-process, which involves the reaction of the phosphate rock with concentrated sulfuric acid. Pure phosphoric acid is only mildly corrosive to metals. However, the presence of impurities in the phosphate ores like chlorides, fluorides and silicates and the free sulfuric acid lead to complex corrosive conditions. The level of impurity depends on the origin of the phosphates and their processing, e.g. washing the ores with sea water further increases the level of chlorides. The corrosive attack is further aggravated b

Resumen
The starting materials for this experiment were monocalcium phosphate monohydrate, dicalcium phosphate dihydrate and anhydrous dicalcium phosphate synthesized in-house from the by-product of a local bone-gelatin manufacture. Porous calcium phosphates comprising hydroxyapatite either as a single phase or a composite containing traces of its congeners. i.e., β-TCP were fabricated in the forms of granules and compacts. The characteristics of typical compacts produced were 37 v % apparent porosity with interconnected pores of diameter 1-30 µm, and flexural and compressive strengths of 17.51 and 78

Resumen
Abstract: Phosphorus is one of the least available macronutrient in the soil. The high affinity phosphate transporters are known to be associated with phosphate acquisition under natural conditions. Due to unique interactions of phosphate with soil particles, up to 80% of the applied phosphates may be fixed forcing the farmers to apply 4 to 5 times the fertilizers necessary for crop production. Efficient uptake and utilization of this essential nutrient is essential for sustainability and profitability of agriculture. Many predictions point to utilization/exhaustion of high quality phosphate r
