Zero-valent iron (ZVI) nanoparticle exists a nanoscale (1-100 nm) of the particle with zero oxidation number. It has acquired considerable attention for its potential to capture free-electron moieties. The production and storage ZVI material, however, is challenging because it relatively unstable. In this research, we aim study solvent effects on preparation characterization. nano-scaled was sy...

Background & objectives: The import of heavy metals into various sources of drinking water supply is one of the major problems of water quality, especially in industrial areas. The aim of this study was to investigate the ability of mercury and arsenic metal pollutants to be removed from aqueous solutions using green oxide nanoparticles synthesized by green method. For this purpose, the extract...

BACKGROUND Accumulating evidence indicates that iron oxide nanoparticles modulate immune responses, and induce oxidative stress in macrophages. It was recently reported that iron oxide nanoparticles attenuated antigen-specific immunity in vivo, though the underlying mechanism remains elusive. The present study investigates the direct effect of iron oxide nanoparticles on antigen-specific cytoki...

Hydrogenation of iron nanoparticles was performed both computationally and experimentally where previously chemically-bonded iron hydride is considered to be unachievable under ordinary conditions. Density functional theory (DFT) calculations predict that hydrogenated iron nanoparticles are stabilized on a single-layer graphene/Cu substrate. Experimentally, iron nanoparticles were deposited ont...

High-valent iron species of oxidation states +4, +5, and +6, have been involved as intermediates in enzymatic reactions, in green organic synthesis, and in purification and disinfection of water. Many of these species have been synthesized to understand their role in different systems, which include ferryl complexes (oxoiron(IV) (Fe IV=O), oxoiron(V) (FeV=O)), iron(IV / V / VI)-nitride complexe...

In this study, Fe(II) complexes of phenyldithiocarbamate, dimethyldithiocarbamate and imidazolyldithiocarbamate were used as single-source precursors to prepare iron sulphide nanoparticles by thermolysis in oleic acid/octadecylamine (ODA) at 180 °C. The nanoparticles were dispersed into hydroxyethyl cellulose (HEC) to prepare iron sulphide/HEC nanocomposites. Ultraviolet-Visible (UV-Vis), Photo...
