Food fortification is an effective, low-cost way to eliminate dietary micronutrient deficiencies in developing countries. This study in Egypt aimed to evaluate the levels of and variations in fortification with iron, iodine and vitamin A in food products from different manufacturers. Almost all iodized salt samples contained iodine concentrations within Egyptian standards. The iron content of i...

fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type sio2/al2o3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by x-ray powder diffraction. the adsorptionof volatile fe(co)5 on the support surface was carried out under vacuum at room temperature. reduction les were monitored by vibrating sample magnetometer...

In this research, a single-stage low-temperature hydrothermal synthesis route was successfully developed for preparation of Iron Disulfide. The prepared powder was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). These analyses showed that nanoparticles were well crystallized, pyrite was the main product and the shape of crystals was nanorod. Also, the influences...

in this work, we report on the synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, ctab as cationic surfactant and butanol as a cosurfactant. surface modification have been carried out by using poly(ethyleneglycol) (peg). the structure,morphology, and magnetic properties of the products were characteriz...

The influence of short-time milling on the atomic structure of amorphous Co(70.3)Fe(4.7)B(25) has been investigated by differential scanning calorimetry (DSC), x-ray powder diffraction (XRD), vibrating sample magnetometer (VSM) and x-ray absorption fine-structure (XAFS) techniques. Our results prove that the milling process crystallizes the initially amorphous sample and that the degree of inhe...

BACKGROUND A link between the provision of iron and infectious morbidity has been suggested, particularly in children with malnutrition. Two meta-analyses concluded that iron is not harmful, but malnourished children were underrepresented in most available studies. OBJECTIVE This study evaluated the effect of iron-containing micronutrient powder (iron MNP) on infectious morbidities when provi...

When a steel pilot plant reactor was emptied, and left exposed to the humid summer atmosphere over a weekend, a heavy corrosion deposit formed on the inner surface. Because the process stream contained triflic acid (trifluoromethanesulfonic acid, CF3SO3H), the engineer wanted to determine whether the deposit contained triflate(s) [1]. The brown deposit was ground in a mortar and pestle. The maj...
