Despite the increasing rate of nanoparticles (NPS) production and their application in agriculture, few studies have focused on their effect on plant growth. So, the present research was conducted in laboratory and greenhouse conditions. First, superparamagnetic iron oxide nanoparticles (SPIONS) with a humic acid coating (Fe3O4/HA) were synthesized in laboratory...

iron oxide (fe2o3) is widely used as a catalyst, pigment and gas sensitive material.  in this article, α-fe2o3 nano-rods were first synthesized via a simple chemical method using iron(iii) nitrate 9- hydrate (fe(no3)3.9h2o) as precursor. xrd pattern showed that the iron oxide nanoparticles exhibited alpha-fe2o3 (hematite) structure in nanocrystals. the single-phase α- fe2o3 nano-rods were prepa...

magnetic nanoparticles can bind to different drug delivery systems and can be used for drug targeting to a specific organ by using an external magnetic field as well as used in hyperthermia by heating in alternating magnetic fields. the characteristics of iron oxide nanoparticles are significantly affected by particle size, shape and zeta potential, among which the particle size plays the most ...

M e t h o d s Design: Randomized controlled trial. Allocation: Unclear allocation concealment.* Blinding: Unblinded.* Follow-up period: 60 days. Setting: A geriatric ward in a hospital in Rehovot, Israel. Patients: 90 patients ≥ 80 years of age (mean age 85 y, 59% women) who were admitted to hospital with a diagnosis of anemia (hemoglobin level 80 to 119 g/L [5.0 to 7.4 mmol/L]) and ferritin le...

background: ultrasmallsuperparamagnetic iron oxide (uspio) nanoparticles are used as blood pool contrast agent for magnetic resonance angiography and perfusion imaging. our aim in this study was to investigate the effect of the two coating types of iron oxide nanoparticles on the relationship between nanoparticles concentration and signal intensity (si) in t1-weighted mr images.   methods : dif...

The Fischer-Tropsch Synthesis converts synthesis gas from alternative carbon resources, including natural gas, coal, and biomass, to hydrocarbons used as fuels or chemicals. In particular, iron-based catalysts at elevated temperatures favor the selective production of C2-C4 olefins, which are important building blocks for the chemical industry. Bulk iron catalysts (with promoters) were conventi...

in the past decade, magnetic nanomaterials have attracted much attention due to their physical properties and technological applications. in this work, α-fe2o3 nanoparticles were first synthesized via a simple co-precipitation method using iron chloride hexahydrate (fecl3.6h2o) as precursor and ammonia solution as precipitator. the samples were then characterized by high resolution transmission...

manganese is one of the significant raw materials for various industries and most difficult element to remove from water because of its high solubility. the treatment of mn (ii) contained wastewater is stringent for environmental preservations. in the present study adsorption of mn2+ on zero-valent iron nanoparticles synthesized by chemical reduction process and modified with phosphate coating ...

Introduction: Iron plays an important role in physiological processes as a trace element. Today, iron oxide nanoparticles have attracted extensive attention due to their super paramagnetic properties and a variety of potential applications in many fields. The main objective of this study was to evaluate in vitro and in vivo toxic effects of the iron oxide nanoparticles on L929 cell line, kid...

Purpose: The presence of tumor-associatedmacrophages (TAM) in breast cancer correlates strongly with poor outcome. The purpose of this study was to develop a clinically applicable, noninvasive diagnostic assay for selective targeting and visualization of TAMs in breast cancer, based on magnetic resonanceI and clinically applicable iron oxide nanoparticles. Experimental Design: F4/80-negativemam...
