This pot experiment was conducted to investigate the effects of ordinary and nano forms of zinc oxide on growth and ion content of four wheat cultivars (Niknejad, Iniya, Rowshan and Moghan2) under three salinity levels (0, 75 and 150 mM NaCl). In this experiment, shoot and root dry weight, and concentration of potassium, sodium and zinc in shoots were measured. Results showed that with an incre...

BACKGROUND Nanoparticles are small-scale substances (<100 nm) with unique properties. Therefore, nanoparticles pose complex health risk implications. The objective of this study was to detect whether treatment with quercetin (Qur) and/or arginine (Arg) ameliorated nephrotoxicity induced by two different doses of nano zinc oxide (n-ZnO) particles. METHOD ZnO nanoparticles were administered ora...

Southern pine specimens vacuum-treated with nano-zinc oxide (nano-ZnO) dispersions were evaluated for leach resistance and UV protection. Virtually, no leaching occurred in any of the nano-ZnO-treated specimens in a laboratory leach test, even at the highest retention of 13 kg/m(3). However, specimens treated with high concentrations of nano-ZnO showed 58-65% chemical depletion after 12 months ...

Background: Synthesis of ZnO nanoparticles (ZnO NPs) is very valuable due to their applications in cancer treatment, unique thermal, optical and electronic properties. In this study, green synthesis of ZnO nanoparticles was performed using Allium jesdianum extract. The green synthesis is a successful process that is environment friendly and low-cost as well. Methods: In this study, the extract...
