چکیده
Nanocrystalline materials may be considered as the challenge of this age. Intensive investigations were stimulated for several applications for these new classes of materials. Zinc oxides of particle size in nanometer range have been paid more attention for their unique properties. They are widely used for solar energy conversion, non-linear optics, catalysis, varistors, pigments, gas sensors, cosmetics etc.1-10 As a wide band gap semiconductor, ZnO has been widely studied in varistors, transparent conductors, transparent U.V. protection films, chemical sensors and so on.11-14

متن کاملPreparation and Characterization of Novel Bionanocomposite Based on Tapioca Starch/Gelatin/Nanorod-rich ZnO: Towards Finding Antimicrobial Coating for Nuts
The effects of zinc oxide nanorod on the barrier, sorption isotherm and antibacterial properties of tapioca starch/bovine gelatin Bionanocomposite films were investigated. The nanorod-rich ZnO (ZnO-N) was homogenized by sonication and incorporated into tapioca starch/bovine gelatin solutions at different concentrations (e.g. 0.5, 2, and 3.5% w/w dried solid). Incorporation of 3.5% of nanopartic...
متن کاملGreen Synthesis of Zinc Oxide Nanoparticles using Garlic skin extract and Its Characterization
Plant-mediated synthesis of metal oxide nanoparticles is a promising alternative to the traditional method of physical and chemical synthesis. In this paper, we report the green synthesis of zinc oxide nanoparticles (ZnONPs) by a biological method. During the study, Zinc oxide nanoparticles were synthesized by Allium sativum skin (garlic skin) extract. Formation of zinc oxide nanoparticles has ...
متن کاملPreparation, characterization and determination of photocatalytic activity of MCM-41/ZnO and MCM-48/ZnO nanocomposites
The direct and indirect methods in solvent media and grinding method in a solvent-free media were used to prepare the MCM-41/ZnO and MCM-48/ZnO photocatalysts. The X-ray diffraction (XRD) patterns showed that zinc oxide nanoparticles were put into MCM-41 and MCM-48 substrates and there were ZnO crystallites as secondary phase in the extra framework of mesoporous materials. The decrease of surfa...
