ron phosphate coatings have found a wide range of use in the metalI finishing industry as a convenient method for achieving reasonably high levels of corrosion resistance. Flexibility of processing parameters and ease of use are probably the biggest reasons that iron phosphating enjoys its continued popularity. The corrosion resistance of iron phosphate coatings can be dramatically improved by ...

Eudialyte-group minerals are of scientific interest as important concentrators rare elements (mainly Zr and REE) in agpaitic alkaline rocks a potential source REE, Zr, Hf, Nb, Ta for industrial use. Extraction uranium(VI), thorium(IV), zirconium(IV), hafnium(IV), titanium(IV), scandium(III) by binary extractant based on 1,5-bis[2-(hydroxyethoxyphosphoryl)-4-ethylphenoxy]-3-oxapentane methyl tri...

Background: Iron-based phosphate binders are widely used in hemodialysis, to avoid the increased mortality associated with high serum phosphate in dialysis patients. However, comparative studies on the effects of phosphate binders are currently limited. In the present study, a comparative analysis of ferric citrate (FC), sucroferric oxyhydroxide (SF), and lanthanum carbonate (LC) was performed ...

industries, its nuclear properties in the pure metallic form make it highly desirable for nuclear applications. Zr is highly corrosion resistant and has a high melting point (2128 K) with a low thermal neutron absorption cross-section of Zr T = 0.18 b, which is significantly smaller than that of hafnium Hf T =115 b) (Speer, 1982), an element that coexists with Zr in nature. This makes Zr ideal ...

Background: To evaluate and compare the microhardness of deciduous teeth treated with nano-hydroxyapatite and calcium sucrose phosphate after iron drop exposure. Material and Methods: Twenty healthy anterior deciduous teeth were collected and stored in 0.9% saline solution at room temperature. All the teeth were immersed in artificial saliva in an incubator shaker at 37° for an hour and then su...

5-Substituted-1H-tetrazoles were synthesized by the [3 + 2] cycloaddition of sodium azide with various nitriles in the presence of nickel zirconium phosphate (NiZrP) as an effective heterogeneous catalyst in dimethylsulfoxide at 120 °C. This method has the advantages of good to high yields, simple methodology and easy work-up. The catalyst can be recovered by centrifuging and reused with good y...

The physiochemical properties of Nafion 115 and a composite Nafion 115/zirconium phosphate (∼25 wt.%) membranes are compared. The composite membrane takes up more water than Nafion at the same water activity. However, the proton conductivity of the composite membrane is slightly less than that for Nafion 115. Small angle X-ray scattering shows that the hydrophilic phase domains in the composite...

Correction for 'The transformation from amorphous iron phosphate to sodium iron phosphate in sodium-ion batteries' by Yao Liu et al., Phys. Chem. Chem. Phys., 2015, 17, 22144-22151.

Abstract The metal retention behaviors of several simulated radiolysis products on zirconium were investigated, and it was found that acid phosphate product HDEHP has the greatest effect. effects extraction nitric concentration, temperature behavior also investigated. results showed forms complexes with resulting in organic phase. Nitric concentration change morphology thus affecting behavior. ...
