در میان روش های مختلفی که برای تخریب آلاینده های شیمیایی مورد استفاده قرار گرفته است، فرایندهای اکسایش پیشرفته (مانند فرایند فتوکاتالیتیکی) به دلیل ویژگی های خاص خود مورد توجه قرار گرفته اند. در این پژوهش، پوشش کامپوزیتی ZnFe2O4-10wt% TiO2 به روش پاشش شعله ای تولید شده است. پودرهای تیتانیا (TiO2 با 75% آناتاز و 25% روتیل) و فریت روی (ZnFe2O4) سنتز شده توسط فرایند آلیاژسازی مکانیکی با یکدیگر مخل...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
In this work, a mineralogical study and thermal decomposition analysis of jarosite residue sample from zinc plant were carried out. The showed that the is mainly composed four components, including jarosites, sulfates–hydroxides, sulfides spinel. distribution relevant metallic elements in these components was characterized using sequential extraction process. X-ray diffraction results AFe3(OH)6...
The composites of the form 0.5ZFO + 0.4BFO 0.1GFO (S1) and 0.75ZFO 0.2BFO 0.05GFO (S2) synthesized by solid state route are reported in this study. These were subjected to structural, energy bandgap dielectric studies. XRD spectral analysis confirms that all three phases present samples under BiFeO3 phase has acquired orthorhombic (Pnma) crystal structure, ZnFe2O4 crystallized into cubic (Fd-3m...
Sol–gel auto-combustion is a unique combination of the combustion and the chemical gelation processes. In this work, nanosize (d) powders with compositions of ZnFe2O4 were synthesized by sol–gel combustion method. The puffy, porous brown powders as-combusted was calcined at the temperature of 750–1000◦C for 4 h. These powders are characterized by X-ray diffraction and scanning electron microsco...
Objective(s): This work focuses on preparing an efficient bacterial capture system based on the magnetic polyphenolic nanostructure. For a reason, a one-step hydrothermally route was employed to prepare ZnFe2O4@hydroxybenzoic acid - resorcinol nanohybrid. Methods: The nanostructure was characterized by X–ray diffraction (XRD), field ...
