This article describes investigations on the phase development (T ≤ 1500℃) of phosphate-bonded Al2O3-MgAl2O4 high-temperature ceramics by a combination solid-state MAS NMR and X-ray diffraction analyses. The ceramic body was bonded with inorganic hydrogen orthophosphates (Al, Mg, Ca, Zr) total binder content 3 wt.% P2O5. binding mechanisms these could be extensively deduced analyses development...

The emergence of biological phosphate esters glycerol could have been a crucial step in the origin and evolution life on early Earth as phosphates today play central role biochemistry. We investigate here formation by employing various rock samples, salts, minerals potential catalysts to aid phosphorylation process. report synthesis including glycerol-1-phosphate, glycerol-2-phosphate, cyclic g...

the aim of this study was to evaluate the ability of microalgae spirulina platensis and chlorella vulgaris to remove nitrate and phosphate in aqueous solutions. spirulina platensis and chlorella vulgar is microalgae was collected in 1000 ml of municipal water and kno3, k2hpo4 was added as sources of nitrate and phosphate in three different concentrations (0.25, 0.35 and 0.45g/l). during the gro...

This experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in Iran. The experiment was a factorial design with three replications. Treatments were four nitrogen biofrtilizers (control (N1), Nitroksin (N2), Azotobacter (N3) and Supernitroplat (N4)) and three phosphate biofrtilizer...
