Organo-iron compounds on clays and pillared clays.
… had a similar Debye temperature in each environment (144 +/- 5 K and 140 +/- 5 K respectively). The intercalated Mossbauer spectra revealed a Karayagin effect above 80 K. The cation occupies 80 % of the total exchange capacity of the clay, most likely orientated with the cyclopentadienyl …

Novel methods for identification and quantification of iron fortificants in cereal flours
<p>Iron deficiency is the most common nutrient deficiency globally. Fortification of cereal grains is a main strategy used to ameliorate global iron deficiency due to its safety and efficacy. For fortification to be effective, fortification programs must use appropriate iron compounds at …

Methods to detect and quantitate spleen added to ground beef
… explore the feasibility of employing the storage iron compounds, hemosiderin and ferritin, as indicators for the detection and quantitation of spleen added to ground beef. Weighed amounts of ground beef and a composite spleen homogenate were combined to yield products with 0, 2.5, 5 and 10 percent …

Strategies to improve non-haem iron absorption
Iron deficiency anaemia is one of the most prevalent nutritional deficiency disorders in the world. Food iron fortification is a widely used strategy to reduce the risk of deficiency but presents a major challenge to the food industry. The more bioavailable forms of iron, such as ferrous gluconate, …

Time controlled photo-oxidation of polyolefins by polymer bound additives
A variety of iron compounds containing vinyl or thiol functional groups (used as photoactivators) have been synthesised and some of these were successfully bound to both polyethylene and polypropylene backbones during processing in the presence of peroxide and interlinking agent. Concentrates …
