background: removing heavy metals from industrial wastewaters by iron nanoparticles has been much noticed in the recent years. chromium is considered as one of the emphasis environmental pollutants. there are high concentrations of chromium in the wastewater of electroplating industries. magnetic iron nanoparticles are used to control and eliminate the heavy metals from industrial effluents thr...

OBJECTIVE The aim of this study was to investigate the mechanical properties (flexural strength, micro-shear bond strength) and remineralizing potential of fissure sealants by adding various concentrations of β-tricalcium phosphate nanoparticles. MATERIALS AND METHODS This in-vitro study consisted of five experimental groups containing prepared nano-fisssure sealants (1-5 wt.% β-TCP nanoparti...

In order to investigate the effect of humic acid (HA) and nano-calcium chelate on the cut flowers of gerbera cv. Dune, an experiment was performed as a completely randomized design with two factors and three replications in hydroponic conditions. The first factor included humic acid at 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor was ass...

transfusion in the treatment of thalassemia gives rise to iron deposits in many organs. since there are many obstacles in the use of deferoxamin (dfo) as an iron chelating agent, it is important to find another alternative therapy that can act as iron chelation. the study aims to compare the histopathological pictures of the heart and spleen in iron-induced rats after administration of dfo and ...

effect of nano titanium oxide, nano zinc and multiwall carbon nano tube on yield and yield components of green gram was carried out in kohkiloyeh-boyrahmad province, iran with 30 degrees 45' n and 50 degrees 44' in 2013 growing seasons. the experiment was arranged as factorial in a completely randomize block design with three replications, treatments including: four concentrations (ze...

Nano particles may be more useful in comparison to bulk materials because they can pass the cell membrane of crops because of their general size. Nano-silicon or SiO2 is one of the major and frequently used engineered oxide nano particles in deferent fields. Quick germination of cultivated seeds and good seedling establishment are key factors to lentil production under salinity stress soil acro...

Background: The application of nano-particles (NPs) in various industries is growing. Since their toxicity is not clearly understood, they can cause adverse effects on the environment. The aim of this study was to evaluate the histopathological effects of iron oxide nano-particles on the small intestine of common carp, Cyprinus carpio. Methods: Four experimental treatments were designed (15 ...

Effects of different concentrations [0, 1, 5, 10, 20 and 40 mgL-1] of Fe3O4 and CuO nano-particles (nFe3O4 and nCuO) were investigated on sulforaphane (SFN) production level in 7-day-old seedlings of Lepidium draba at different time intervals (8 and 16 hrs). According to the results, the influence of the particles on SFN contentdepends on nano-particle (NP) concentrations, time of treatment as ...
