iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...
Introduction: Recent findings revealed the biological effects of iron oxide nanoparticles on the central nervous system. Moreover, the brain cholinergic system plays a role in the modulation of anxiety behaviors. Therefore, this study aimed to evaluate the role of dorsal hippocampal muscarinic cholinergic receptors of the CA1 area on anxiety induced by iron oxide nanoparticles in adult male rat...
In this present work effect of temperature and graphite contents on the microstructural and mechanical properties of iron based powder metallurgy freeform was studied. The different graphite contents (0%, 2%, 5% and 10%) were mixed in iron powder and compact them in 100 KN. These specimens were sintered at 7000 C, 8500 C and 10000 C in muffle furnaces. Microstructural properties were evaluated ...
Iron oxide scale generally forms on low-carbon steel surfaces during the hot rolling processes andproduces as solid waste more than 100 thousand tons per year. The utilization of iron scaleis one possible way to reduce production cost for plants and promote environmental protection. Acrylonitrile-Butadiene-Styrol-Copolymer (ABS) is widely used engineering plastic automotive parts because its hi...
The effects of powder particle size on the densification and microstructure of iron powder in the direct laser sintering process were investigated. Iron powders with particle sizes ranging from 10 to 200 m were used. It was found that the sintered density increases as the laser energy input is increased. There is, however, a saturation level at which higher density cannot be obtained even at ve...
In recent years, a lot of research has been done in the field of producing soft magnetic nano composites by means of mechanical alloying. These materials indicate more electrical resistance and permeability in comparison with soft magnetic composites (SMCs). In this research, reduction of silicothermal mixed powder (Nickel-oxide, Silicon and Iron) was carried out by mechanical alloying to form ...
Background and purpose: Removal of lead as a toxic metal from contaminated water resources is necessary due to the dangerous effect of lead. One of the most effective methods of removal is the adsorption process. The aim of this study was adsorption and magnetic separation of lead from synthetic wastewater using iron oxide nanoparticles and carbon (ION/C) composite Material and Methods: In ...
Iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. We aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt. Fifteen adult rabbits were divided into 3 groups o...
Background and Objectives: Cadmium is a heavy metal, which has high toxicity and high accumulation properties in living tissue. The purpose of this study was to determine the efficiency of iron oxide nanoparticles in the adsorption of cadmium from aqueous media. Materials and Methods: This laboratory study was performed in the summer of 2018. XRD (X-ray powder diffraction) and SEM (scanning e...
