proper feeding is necessary to have appropriate growth, health and also to increase resistance to inappropriate condition such as stressors and diseases. therefore mineral and vitamin supplements are added to fish diet to improve its growth and health. food supplements have different roles in diet. these cause better food metabolism, higher hardness and strength of bones, better ionic exchanges...

The Class F fly ash has been subjected to high energy ball milling and has been converted into nanostructured material. The nano structured fly ash has been characterized for its particle size by using particle size analyzer, specific surface area with the help of BET surface area apparatus, structure by X-ray diffraction studies and FTIR, SEM and TEM have been used to study particle aggregatio...

Nanocrystalline nickel ferrite (NiFe2O4) has been synthesized from a stoichiometric mixture of oxides NiO and α-Fe2O3 in a high energy planetary mill. A post milling annealing at 350 °C was used to improve the solid state reaction. The obtained powders were investigated by X-ray diffraction, magnetic measurements, scanning electron microscopy, X-ray microanalysis, differential scanning calorime...

this study was conducted to enhance the antimicrobial properties and water absorption of sanitary papers. for this purpose, montmorillonite nano clay with bentonite brand (has a layered structure in which its thickness is nano metric), was processed with homogenizer to achieve a stable colloidal system with nanometer dimensions of particle size. then, different weight levels of raw and homogeni...

The reaction mechanism for conversion of MnO nanoparticles to Mn-ferrite nanoparticles was studied, which involved sequential consumption of MnO and the growth of ferrite. The method could be applied to other ferrite nanoparticles including cobalt ferrite.

Cobalt ferrite, Copper ferrite and cobalt doped copper nanoparticles have been synthesized characterized using different characterization methods (XRD, FTIR FESEM). The prepared used as promising fillers of the polyvinylidene fluoride (PVDF) polymer. PVDF/(Cu–CoFe2O4, CoFe2O4, CuFe2O4) nanocomposites films via a simple solution casting technique. optical properties piezoelectric response nanoco...

elastomer compound based on nr/br was prepared using different kinds of nano-zno and zno. the effect of zinc oxide as an activator of sulfur cure on the mechanical and morphological properties of the compound was studied. the result of the mechanical properties showed that the tensile strength, elongation-at-break, resilience, and abrasion resistance of the compound prepared by zno (4 phr) are ...

in this research fe-tio2 nanocomposites with different molar ratios of fe/ti were prepared as nano-photocatalyst using a modified sol-gel process at ambient temperature. crystallographic properties of nanocomposites were characterized by x-ray diffraction (xrd). surface morphology and mean particle size of nanocomposites were specified by field emission scanning electron microscopy (fesem) and ...
