Nano-scale zero-valent iron (nZVI) is one of the most intensively studied materials for environmental cleanup uses over the past 20 years or so. Freshly prepared nZVI is highly reactive due to its high specific surface area and strong reducing power. Over years, the classic borohydride reduction...
aVarious compounds containing iron,aluminum, ammonium, and phosphate were prepared by solution and by fusion methods, in an attempt to obtain a compound which would give the same x-ray diffraction pattern as the residue mentioned above. Materials precipitated from solution gave the desired pattern....

Iron and its regulation In the form of ferrous iron (Fe2+), heme, or iron sulfur clusters (ISCs), iron acts in the catalytic centers of a number of important enzymes, such as ribonucleotide reductase and DNA helicase during DNA replication, nitric oxide synthases in governing second messenger...

It is a biologically essential component of all living organisms and plays a key role in exercise-related processes [2,3]. Fe is mainly found in the body in complex forms bound to proteins (hemoproteins) such as heme compounds (hemoglobin or myoglobin), heme enzymes (cytochromes) or non-...
Iron-oxide earth pigments yield ochres (yellow-browns), siennas (orange-browns), and umbers (browns). Certain compounds of chromium are used to provide chrome yellows, oranges, and greens, while various compounds of cadmium yield brilliant yellows, oranges, and reds. Iron, or Prussian, blue ...
Iron compounds areamenableto study by taking advantage of a phenomenon known as theMössbauer effect(the phenomenon of agamma raybeing absorbed and reradiated by a nucleus without recoil). Although the Mössbauer effect has been observed for about one-third of the elements, it is particularly ...
It is quite interesting that PVA has a property of forming complexes with inorganic ions and compounds and even organic substances in a wide pH range 1 - 6 ; some of the complexes are colloids or gels. Much attention has been paid to the usefulness of these complexes as functional materials...
