A feasibility study on the possible growth of rod-shaped nano size zinc oxide particles on the surface of polyester fabric was investigated. The nanoparticles were produced using a hydrolysis method, with a zinc compound being utilized as the starter material. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy/energy dispersive X-ray spectrometry (SEM/EDS) and X-ray d...

zinc oxide nanoparticles have been synthesized by chemical reaction method.  polyvinyl alcohol (pva) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by pva solution and nanozinc oxide. polymer blend with zno nanoparticle composite film has prepared by casting technique.  the property of nano composites depends greatly on the chemistry of polymer matrices....

Wet thermal oxidations of polycrystalline Si0.54Ge0.46 films at 600°C for 30 and 50 min were carried out. A stable mixed oxide was obtained for films that were oxidized for 50 min. For film oxidized for 30 min, however, a mixed oxide with Ge nanocrystallites embedded in the oxide matrix was obtained. A trilayer gate stack structure that consisted of tunnel oxide/oxidized polycrystalline Si0.54G...

BACKGROUND Antibiotic resistant bacteria can be considered as a main problem in infection management. Zinc oxide nanoparticles (ZnO NPs), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. METHODS In this study, Zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

Growth and evolution of germanium (Ge) nanocrystals embedded into a silicon oxide (SiO2) system have been studied based on the Ge content of co-sputtered Ge-SiO2 films using transmission electron microscopy (TEM) and Xray photoelectron spectroscopy (XPS). It was found that when the proportion of Ge relative to Ge oxide is 20%, TEM showed that annealing the samples at 800C for 60 min resulted in...

introduction: intrinsic tooth discolorations after endodontic treatment are principally attributed to the composition of necrotic pulp tissue, hemorrhage within the pulp cavity, endodontic medicaments and/or filling materials. residual sealer left in pulp chamber after obturation can cause discoloration. the objective of this in vitro study was to evaluate coronal discoloration created by ah26 ...

background & objectives: direct addition of antimicrobial materials to food during food processing is an effective method for controlling microbial contaminants of food and extending the shelf-life of food products. objective of this research was to study the antimicrobial effect of zinc oxide (zno) nanoparticle and potential applications of zno nanoparticles in terms of controling two food...
