Mössbauer spectroscopy is an indispensable spectroscopic technique and analytical tool in iron coordination chemistry. The linear correlation between the electron density at the nucleus ("contact density") and experimental isomer shifts has been used to link calculated contact densities to experimental isomer shifts. Here we have investigated relativistic methods of systematically increasing so...

The distribution of iron between the sheaths and the cells of iron-inhibited Sphaerotilus cultures was determined. The experiment was conducted with different soluble iron forms as inhibitors. The growth inhibition was found to be related to the iron sorbed by the cells rather than by the sheaths. At the 90% inhibition level, iron sorbed by the cells ranged from 13 to 15 mg/g of organism for al...

Solid iron compounds are extremely common in the environment as well as in meteorites and comets. Fe K-edge XANES (X-ray absorption near-edge structure) measurements can be carried out quickly, theoretically allowing one to categorize many areas within a sample or set of samples in a short time. However, interpretation of such data is not straightforward unless one has the appropriate reference...

Listeria monocytogenes is a ubiquitous potentially pathogenic organism requiring iron for growth and virulence. Although it does not produce siderophores, L. monocytogenes is able to obtain iron by using either exogenous siderophores produced by various microorganisms or natural catechol compounds widespread in the environment. In the presence of tropolone, an iron-chelating agent, growth of L....

Irradiation of a toluene solution containing cyclopentadienone tricarbonyl iron complexes and isocyanides with blue LEDs afforded the formation isolation 12 triisocyanide complexes, two which, namely tris(2,6-dimethylphenyl isocyanide)(η 4 -tetraphenylcyclopenatedienone)iron, [Fe(C 9 H N) 3 (C 29 20 O)], tris(naphthalen-2-yl -tetraphenylcyclopenatedienone)iron acetone hemisolvate, 11 7 O)] 2 ·C...

Bioavailability of a single iron source is difficult to predict. It can vary considerably due to the enhancing or inhibitory effects of other food components on iron absorption and, especially for the less-available sources, it is strongly influenced by the physical characteristics of the iron compound itself. It is sometimes difficult for the food manufacturer or food scientist to interpret th...

With the challenge of optimizing iron delivery, new intravenous (iv) iron-carbohydrate complexes have been developed in the last few years. A good example of these new compounds is ferric carboxymaltose (FCM), which has recently been approved by the US Food and Drug Administration for the treatment of iron deficiency anemia in adult patients who are intolerant to oral iron or present an unsatis...
