To evaluate the physiological responses of chrysanthemum to silicon spray in non-stress conditions, this study was performed in two separate experiments (at 4 to 5 and 8 to 12-leaf stages) as a factorial randomized completely design with two factors: silicon source (in two levels: sodium silicate and calcium silicate) and the concentration of silicate at five levels (0, 50, 100, 150 and 200 mg ...

partial least squares modeling as a powerful multivariate statistical tool was applied tothe simultaneous spectrophotometric determination of silicate and phosphate in aqueoussolutions. the concentration range for silicate and phosphate were 0.02-0.6 and 0.4-3 μg ml-1,respectively. the experimental calibration set was composed with 30 sample solutions using amixture design for two component mix...

As the most abundant material of rocky planets, high-pressure polymorphs iron- and aluminum-bearing magnesium silicates have long been sought by both observations experiments. Meanwhile, it was recently revealed that iron oxides form (FeO)m(Fe2O3)n homologous series above ?10 GPa according to laboratory Here, we report a new iron-magnesium silicate, approved International Mineralogical Associat...

The effect of spherulitic crystallization on the elastic moduli and fracture toughness a barium aluminum silicate glass was investigated. process results in Ba2Si3O8 phase is initiated from Ba rich nuclei. Nucleation optimal 690-720 °C interval. Young’s modulus increased by 12.5% when glass-ceramic conversion nearly complete. Nevertheless, as size volume fraction crystals are increased, some mi...

Abstract In the present paper, structure as well solubility and thermodynamic data of synthesized Al‐tobermorite is discussed. 29 Si NMR XRD prove successful synthesis an with a ratio Al/(Al + Si) = 0.1. The aluminum incorporated in branching (Q 3 ) sites silicate chains. Solubility can be calculated from measured ionic concentrations storage aqueous solution, which show little variation over t...

Plasma electrolytic oxidation (PEO) was performed on a 1010 Aluminum alloy. To achieve thenanocomposite structure, Si3N4 nanoparticles were added into the electrolyte. In an alkaline aqueoussuspension (silicate-based), the effect of adding NiSO4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of PEO coatings was investigated using ScanningElectron Microscopy (...
