Background: Zinc oxide (ZnO) nanoparticles are used for various industrial and domestic purposes and its release into the environment leads to the adverse effects among humans. This study aimed to evaluate the effect of rat exposure to ZnO nanoparticles on the histopathology of the liver and pancreas tissues, and serum oxidative stress parameters. Methods: Eighty female adult Wistar rats were ...

By sputtering a layer of 40 nm Ag film on ZnO microrods prepared by the aqueous solution method, we observed photoluminescence enhancement from ZnO microrods coated with Ag nanoparticles, comparing with pure ZnO microrods. The ratio of the enhancement, in particular, reaches 6.6 at 396 nm. The enhancement mechanism is attributed to the special distribution of the silver nanoparticle film, which...

Over the past few decades, nanomaterials of metal oxide such as zinc (ZnO) have been significantly researched for sensing various toxic gases like ethanol, acetone and ammonia. The performance semiconducting materials depends primarily on their surface structure interaction behavior with target gas molecules. quality ZnO is highly influenced by deposition methods. Although several surfaces rigo...

results analysis by xrd showed 78.1% zno (sized 24 nm), 2.5% zn (sized 44.88 nm) and 4.8% zns (sized 12 nm) produced by p. stutzeri. the nanoparticles showed anti-bacterial activity against some of the gram positive and negative bacteria. in addition, the nanoparticles showed magnetic properties. the best condition for nano zinc production was at ph 7, in the light and at 37 °c. czcc gene with ...

The rapid growth in nanomaterial applications have revealed limitations in available physicochemical characterization methods. An in situ electrochemical small-angle neutron scattering (eSANS) methodology was devised that enables direct measurements of nanomaterial dispersion structure while undergoing reduction-oxidation (redox) reactions at the vitreous carbon electrode. Furthermore, these po...

Vertically aligned Zn2SiO4-SiOx(x < 2) core-shell nanotube arrays consisting of Zn2SiO4-nanoparticle chains encapsulated into SiOx nanotubes and SiOx-coated Zn2SiO4 coaxial nanotubes were synthesized via one-step thermal annealing process using ZnO nanowire (ZNW) arrays as templates. The appearance of different nanotube morphologies was due to size-dependent thermal instability and specific mel...

Abstract The spatial organization of metal oxide nanoparticles represents an important factor in the chemical utilization resulting structures. For production networks that are composed nanoparticle chains, we dispersed vapor phase-grown TiO 2 and ZnO homogeneously aqueous polyvinyl alcohol solution. After electrospinning, analyzed sizes diameters compositionally homogeneous electrospun fibers ...
