Iron-Rich Cordierite

Carbohydrate metabolism of iron-rich and iron-poor Staphylococcus aureus.

Comparative studies were made of the metabolic activities of a strain of Staphylococcus aureus grown in iron-poor and iron-rich trypticase medium, with and without glucose. Four nutritionally distinctive types of organisms were produced : iron-rich without glucose (Fe + G ) ; ironpoor without glucose (Fe G ) ; iron-rich with glucose (Fe + G + ) ; iron-poor with glucose (FeG + ) . Fe+ G cocci ox...

Fighting iron deficiency anemia with iron-rich rice.

OBJECTIVE Iron deficiency is estimated to affect about 30% of the world population. Iron supplementation in the form of tablets and food fortification has not been successful in developing countries, and iron deficiency is still the most important deficiency related to malnutrition. Here we present experiments that aim to increase the iron content in rice endosperm and to improve its absorption...

Cordierite Granite from Terip Terip, Victoria

Crystallization Phenomena in Iron-rich Glasses

In this study, results of the crystallization of iron-rich glasses are summarized. Thermogravimetry (TG)±di€erential thermal analysis (DTA) were utilized to explain the phase formations and the surface oxidation of FeO to yield Fe 2 O 3. The crystal phases fraction was evaluated utilizing X-ray di€raction analysis (XRD). Low angle XRD technique was used to investigate the distribution of the cr...

Structural investigations of the two polymorphs of synthetic Fe-cordierite and Raman spectroscopy of hexagonal Fe-cordierite.

The crystal structures of synthetic hexagonal and orthorhombic Fe-cordierite polymorphs with the space groups P6/mcc and Cccm were refined from single-crystal X-ray diffraction data to R1, hex = 3.14 % and R1, ortho = 4.48 %. The substitution of the larger Fe2+ for Mg leads to multiple structural changes and an increase of the unit cell volumes, with a, c (hex) = 9.8801(16) Å, 9.2852(5) Å and a...
