Fe-Ag nanocomposite: Hydrothermal preparation of iron nanoparticles and silver dendrite like nanostructures

At the first stage Fe3O4 and Fe nanoparticles were synthesized via a simple hydrothermal method. Then silver nanoparticles and Fe-Ag nanocomposites were synthesized in the presence of NaBH4. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy, and Fourier transform infrared spectroscopy. Vibrating Sample magnetometer illustrated that Fe nanopartic...

Understanding the role of iron in the magnetism of Fe doped ZnO nanoparticles.

The actual role of transition metals like iron in the room temperature ferromagnetism (RTFM) of Fe doped ZnO nanoparticles is still an unsolved problem. While some studies concluded that the Fe ions participate in the magnetic interaction, others in contrast do not believe Fe to play a direct role in the magnetic exchange interaction. To contribute to the understanding of this issue, we have ca...

Oxidative stress induced by zero-valent iron nanoparticles and Fe(II) in human bronchial epithelial cells.

To identify the mechanism through which nanoparticulate zero-valent iron (nZVI; Fe0(s)) damages cells, a series of experiments were conducted in which nZVI in phosphate-buffered saline (PBS) was exposed to oxygen in the presence and absence of human bronchial epithelial cells. When nZVI is added to PBS, a burst of oxidants is produced as Fe0 and ferrous iron (Fe[II]) are converted to ferric iro...

Assessment of Phenol Removal Efficiency by Synthesized Zero Iron Nanoparticles and Fe Powder Using the Response Surface Methodology

The purpose of this study was the investigation of the removal of phenol with nanoparticles zero valent iron and iron powder. The effect of various parameters such as initial concentration, pH, contact time, and dosage of NZVI and Fe powder was examined, and a Central Composite Design (CCD) was then applied to appraisal the effect of these variables. The chemical and physical characteristic...

Role of Iron (Fe) in Body

Iron is an essential element for most life on Earth, including human beings by participating in a wide variety of metabolic processes, including oxygen transport, DNA synthesis, and electron transport. Iron is needed for a number of highly complex processes that continuously take place on a molecular level and that are indispensable to human life, e.g. the transportation of oxygen around your b...
