Contrastingly small iron oxides

Nature Biomedical Engineering, 2017
Uniform iron oxide nanoparticles with a hydrodynamic diameter of about 12 nm offer high biocompatibility and diagnostic yield as contrast agents for the magnetic resonance imaging of large animals.

Determination of metallic iron, iron(II) oxide, and iron(III) oxide in a mixture

Talanta, 1968
A procedure is described for the estimation of metallic iron, ferrous oxide, and ferric oxide when present together. The sample is treated with bromine dissolved in ethanol, and filtered. Iron in the filtrate is titrated iodometrically, and corresponds to the metallic iron present in the mixture.

Iron oxidation by casein

Biochemical and Biophysical Research Communications, 1992
Casein accelerates the oxidation of Fe(II) to Fe(III) and the resulting Fe(III) remains strongly bound to the casein. Removal of phosphate from the casein abolishes the oxidative process. The oxidation rate is proportional to the casein concentration, and with high casein concentrations the rate is pseudo-first-order with respect to Fe(II) with a half ...
