Nano-composite copper-zinc oxide (NCCZO) was deposited on borosilicate glass using a novel sol-gel/doctor-blade technique. The photocatalyst was prepared from copper acetylacetonate, zinc acetylacetonate, monoethanolamine (MEA) and citric acid monohydrate at 75 oC, aged for 1 d and annealed at 650 oC. The properties of the NCCZO nano-composite were investigated by X-ray diffraction (XRD) and fi...

nano-graphene oxide was synthesized by the oxidation of graphite powders. the structural nature of the nano-graphene oxide was characterized by a variety of techniques including xrd, tem, ft-ir and uv/vis. the functional groups on its basal planes and edges of nano-grahene oxide play important role in catalytic activity. the catalytic activity of nano-graphene oxide was investigated on crossed-...

Abstract Stabilization of nano-oxide suspensions is a very important process. Nowadays, synthetic polymers are used to increase stability the colloidal systems. However, this solution not ecological and incompatible with principles green chemistry. Instead polymers, their natural counterparts can be used. Herein, we present use bioactive polysaccharide—fucoidan as stabilizer nano-zinc(II) nano-...

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...

in internal combustion engines, only about a third of the total fuel input energy is converted into useful work. if the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. the main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing cerium...

INTRODUCTION The aim of this animal study was to evaluate the histological response of the new nano zinc-oxide eugenol (NZOE) sealer in comparison with Pulp Canal Sealer (ZOE based) and AH-26 (epoxy resin sealer). METHODS AND MATERIALS A total of 27 Wistar rats were used. Four polyethylene tubes were implanted in the back of each rat (three tubes containing the test materials and an empty tub...

zno nanoparticles were synthesized by a microwave-assisted chemical method. zno nanostructures were synthesized via a fast reaction between zinc acetate and ammonia at presence citric acid and other effective agents in chemical procedure. nanostructures were characterized by x-ray diffraction , scanning electron microscopy. seed yield and seed quality of safflower grown under drought stress. th...

Abstract We report a “nano-on-micro” approach for growth of cactus-like nanostructures zinc oxide (ZnO) gas sensing application. use electrospun polymeric fibers doped with catalyst nanoparticles as the template and employ vapor-liquid-solid (VLS) method to ZnO nanostructures. Controlling processing variables in VLS process yields needle-like around fibers, which resembles needles cactus. The n...
