Fe2+/ Fe2+ Calculation In Spinels From Oxygen Deficiency Sum

Response to "Comment on 'Fe2: As simple as a Herculean labour. Neutral (Fe2), cationic (Fe2(+)), and anionic (Fe2(-)) species"' [J. Chem. Phys. 144, 027101 (2016)].

Redetermination of Fe2[BP3O12]

Explorations of phases in the quaternary Fe(III)-B(III)-P(V)-O system prepared by the high temperature solution growth (HTSG) method led to single-crystal growth of anhydrous diiron(III) borotriphosphate, Fe(2)[BP(3)O(12)]. This phase has been synthesized previously as a microcrystalline material and its structure refined in space group P3 from powder X-ray diffraction data using the Rietveld m...

Thermoelasticity of Fe2+-bearing bridgmanite

We present local density approximation augmented by the Hubbard-type correction calculations of high-temperature elastic properties of bridgmanite with composition (Mg(1−x)Fe x )SiO3 for 0≤×≤0.125. Results of elastic moduli and acoustic velocities for the Mg end-member (x=0) agree very well with the latest high-pressure and high-temperature experimental measurements. In the iron-bearing system,...

BINDING OF Fe2+ BY MAMMALIAN FERRITIN

An average of 140 Fe 2 + ions bind to mammalian ferritin that has an average core content of 1876 Fe+ ions per molecule. The Fe2+ ions enter the protein interior and exchange electrons with the core Fe+ ions. A non-homogeneous model for the iron-eontaining core of ferritin is proposed.

NMR probe of pseudogap characteristics in Fe2¿xV1ÀxAl

We report the results of a V nuclear magnetic resonance ~NMR! study of Fe21xV12xAl, near the ordered composition with x50, at temperatures between 4 and 500 K. All compositions are found to be metallic or semimetallic, though electrical resistivity has indicated a metal-insulator transition at x50. The lowtemperature NMR relaxation rates for stoichiometric (x50) and nonstoichiometric (x50.10 an...
