Background & Aims: In recent years, iron oxide nanoparticles have been used in contrast-enhanced magnetic resonance imaging for diagnosing a wide range of diseases. In order to provide biocompatibility and prevent the toxicity of the nanoparticles, using organic or inorganic coating around these nanoparticles is important for their application. The aim of this study is to investigate the effect...
Rapid population growth has evolved the big problem of limited fresh water supply in the world and the wastewater treatment is the only recycling process which can overcome this problem. Technology advancement has led us to the nanotechnology which is having tremendous scope for wastewater treatment. Nanoadsorbents, magnetic nanoparticles, nanofiltration, nano zero valent iron, nanocatalysts, n...
This study investigated the effect of the inoculation of the soil with some phosphorus solubilizing microorganisms (PSM) on inorganic P fractions in sandy soil enriched with inorganic and organic amendments. A factorial experiment arrangement was performed in a completely randomized design with three replications, using two factors: microorganisms (control, Entrobacter cloacae, Brevundimonas, a...

Understanding the interactions between natural organic matter (NOM) and zero-valent iron nanoparticles (nano-Fe0) and magnetite nanoparticles (nano-Fe3O4) is essential for evaluating their performance in pollutant remediation, as well as determining their fate and transport in the environment. Batch experiments were performed to investigate the sorption/desorption behaviors of humic acid (HA) o...
Aims In recent years, iron oxide nanoparticles have shown incredible possibilities in biomedical applications due to their non-toxic function in biological systems. Furthermore, these nanoparticles have multifunctional applications, such as antibacterial, antifungal, and anticancer effects in medicine due to their magnetic properties. Methods & Materials In this article, 49 articles related t...
The transport characteristics of iron nanoparticles prepared with a green tea, polyphenol-rich solution, were investigated for two granular media, pure silica sand and sand coated with aluminium hydroxide. The GT-nZVI injection caused a sharp decrease in the effluent pH and increase in the redox potential, which is attributed to the presence of free Fe and polyphenols in the suspension, respect...
Reactive interlayers consisting of zero valent iron and copper nanoparticles have been successfully incorporated into Surlyn films to fabricate moisture barrier materials with reduced water vapor permeabilities. The reactive nanoparticles dispersed in stearic acid were employed as the interlayers due to their ability to react with moisture. The water vapor transmission rates through the fabrica...
Background and aims: Volatile organic compounds (VOCs) are of environmental concern because of their adverse effects on human health. VOCs contain a large group of substances like toluene. Today application of catalytic beds is one the ways to control these kinds of emissions. In this study photocatalytic removal of toluene vapour by titanium dioxide nanoparticles immobilized on ZSM-5 zeolite h...
