basil (ocimum basilicum l.) belongs to the lamiaceae family as a medicinal plant used in traditional medicine in iran. the purpose of this test is to evaluate the effect of nano fe-chelate under salinity levels on the plant physiology and morphology characteristics. in this experiment investigated the effect of nano fe-chelate and salinity stress on growth parameters, photosynthetic leaves rat...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
In the present study, the effect of Iron Nitrate as catalytic precursor to in situ formation of nano-Fe particles in phenolic resin and microstructural evolution of MgO-C refractories has been investigated. Therefore, various samples according to matrix section formulation of low carbon MgO-C refractories (LCMCR’s) with 0 and 6 wt% (Fe/Phenolic resin) were prepared and phase and microstructure ...
Background: Biotic and abiotic elicitors produce secondary metabolites and alter physiological traits of the plants by affecting some of the mechanisms within the plant cells. Objective: This study was aimed to investigate the effects of different concentrations of spherical nano-carbon and salicylic acid on physiological traits and paratolenolidae content in Feverfew. Methods: This research ...
MicrosoftInternetExplorer4 Background and Objectives: Nitrate is one of the most groundwater pollutants in world. Reduction of nitrate to nitrite by microorganisms cause serious health hazards. Nitrate can be eliminated using either adsorbtion or reduction. In this study, we investigated the adsorption of nitate on zeolite and the feasibility of removal improvement using supported zero v...
Superparamagnetic iron oxide nanoparticles (SPIONs) have made extensive advances in nanotechnology. The unique properties of these particles have expanded their application in various fields, including medicine. One of these applications is non-invasive analysis for cell tracking. However, the possibility of toxicity in cells is reported by these nanoparticles. Due to the fact that cellular dam...
introduction iron (fe) has a crucial biological role in human and plant growth. this micronutrient is a major player in chloroplast photosynthesis and enzymes. although some enzymes, such as fe-dependent superoxide dismutase, use molecular fe as a cofactor directly, most proteins use fe-containing factors. various studies were carried out to understand the effect of nanoparticles on the growth ...
The aim of this study was to investigate the effects of iron and copper on bovine oocyte maturation, preimplantation embryo development and apoptosis of blastocysts. The concentrations of iron in the culture media were 0 (control), 0.45, 0.81, 1.96 and 3.26 mg/l, and the concentrations of copper were 0 (control), 0.093, 0.27, 0.46 and 0.68 mg/l. The changes in the iron (1.96 mg/l) and copper co...
Abstract The research was carried out in lath house of the Department Horticulture and Landscaping - College Agriculture / University Anbar during two growing season 2021-2022, order to study effect spraying with normal nano iron on growth flowering petunias. Normal used concentrations (0, 50 100 mg L -1 ), which represented by (F0, F1 F2) respectively, while sprayed 10 20 ) it (NF0, NF1 NF2) r...
Toxicity tests were performed to investigate possible harmful effects on medaka exposed to nano-iron. Dose-dependent decreases of superoxide dismutase (SOD) and increases of malondialdehyde (MDA) were induced in the medaka embryo, suggesting that oxidative damage was induced by nano-iron. For adult medaka, the disturbance of antioxidative balance was observed during the early exposure period ba...
