Nanoparticles (NPs) with unique physicochemical properties induce nano-specific (excess) toxicity in organisms compared with their bulk counterparts. Evaluation and consideration of nano-specific toxicity are meaningful for the safe design and environmental risk assessment of NPs. However, ZnO NPs have been reported to lack excess toxicity for diverse organisms. In the present study, the nano-s...

Abstract The effects of engineered nanoparticles (ENPs) in living organisms are described in a myriad of articles. Most of the literature on this topic is devoted to plants of different gender and species. Studies from laboratories and greenhouse facilities highlight effects on chlorophyll production, plant growth, stress enzyme activities, phytotoxicity, cytotoxicity, and genotoxicity. With fe...

This study reports on the synthesis of zinc oxide (ZnO) nanostructures and examines the performance of polymer nanocomposites fabricated using ZnO dispersed in polymer host matrices. The polymer matrix used was an epoxy based thermosetting polymer known as Diglycidyl Ether of Bisphenol-A(DGEBA). Zinc oxide nano particles were prepared by precipitation method using Poly Vinyl Alcohol as the surf...

Here we demonstrate a single-pot heating approach for controllable synthesis of colloidal zinc oxide nanocrystals from zinc acetylacetonate. Such single-pot heating approaches are inherently amenable to large scale production. We have systematically studied the crystallization process, investigating the growth of nanocrystals and the influence of ligands on the morphology and luminescence of Zn...

In this study, a multi nanosensor was fabricated for the simultaneous detection of carbon dioxide, methane, ethanol, and ammonia gases, and its electrochemical response to various concentrations of these gases were investigated. In order to fabricate this multi nanosensor, in the first phase, the Graphene-Oxide/Polyaniline (GO/PANI) nanocomposite was synthesized. Chemical ...

The maximum magnetisation (saturation magnetisation) obtainable for iron oxide nanoparticles can be increased by doping the nanocrystals with non-magnetic elements such as zinc. Herein, we closely study how only slightly different synthesis approaches towards such doped nanoparticles strongly influence the resulting sub-nano/atomic structure. We compare two co-precipitation approaches, where we...

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...
