Research ArticleOpen accessIn the abstractToxicity of Zinc Oxide Nanoparticles in Lung Tissue After Repeated Oral AdministrationAtaollah Shokouhian, Saman Soheili, Saeed Moradhaseli et al.Pathological experiments should be considered following oral administration of ZnO. Effect of different doses of ZnO nanoparticle on LDH in oral method showed significant differences in control group (p<0.05) at high dose. Levels of IgG, TNF-α and IL-6 also elevated after administration of ZnO. The level of GSH decreased significantly. Lung damages included hyperemia and bleeding, atelectasis, light emphysema, pribronchiolitis, … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 4 · 21 Oct 2013 · 7,703 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Annealing Temperature on Characteristics of Bismuth Doped Zinc Oxide FilmsSirirat Tubsungnoen Rattanachan, Phanuwat Krongarrom, Thipwan FangsuwannarakIn this study, Bismuth (Bi) doped ZnO thin films were deposited on quartz substrates by a sol-gel spin coating method and annealed at different annealing temperatures of 200, 300, 400, 500, 600 and 700°C, respectively. Structural and optical properties of nanocrystalline Bi-doped ZnO film on quartz were investigated by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and UV-VIS spectrophotometer. … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 1 Oct 2013 · 7,126 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Milling Time on Ni0.5Zn0.5Fe2O4 Compositional Evolution and Particle Size DistributionI. Ismayadi, M. Hashim, A. M. Khamirul, R. AliasProblem statement: This study involved an investigation to ascertain the diffusion of NiO and ZnO into the tetrahedral and octahedral sites using mechanical alloying method. The effect of mechanical alloying towards particle size was also reported. Approach: NiO, ZnO and Fe2O3 precursors were mechanically alloyed to synthesis ultrafine powders of Ni0.5Zn0.5Fe2O4. Various milling times were employed to study the effect … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,998 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Dietary Yeasts Enriched with Cu, Fe and Mn on Digestibility of Main Nutrients and Absorption of Minerals by Growing PigsDaniel Korniewicz, Zbigniew Dobrzanski, Katarzyna Chojnacka et al.Yeasts Saccharomyces cerevisiae containing in 1 kg of dry product, separately 32.0 g Fe (Y-Fe), 23.0 g Cu (Y-Cu), 35.4 g Mn (Y-Mn), were used as the source of these microelements in complete diet for growing pigs. If considering livestock requirements, feed supplementation with this organic form of microelements, covered animals’ requirements in: Fe-27%, Cu-75%, Mn-30%. ZnO was the source … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,707 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of ball milling times on phase formation of Mg0.7Zn0.3Fe2O4Aurawan Rittidech, Panuthat KhotsongkramMg0.7Zn0.3Fe2O4 (MZF) powder was prepared by a solid-state mixed oxide using ball-milling technique. The phase identification of calcined powders was performed using X-ray diffraction technique (XRD). It has been found that MZF powders were successfully obtained for calcination conditions of 800 oC for milling times of 36 h, whereas milling times of 12 h, unreacted ZnO, Fe2O3 and MgO phases … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,324 accessesView PDF Cite
