In the title compound, [Fe(H(2)O)(6)][FeBr(3)(CO)(3)](2), both Fe atoms have an octa-hedral coordination and the bromide carbonyl complex has a fac-stereochemistry. The [Fe(H(2)O)(6)](2+) octa-hedron has point symmetry and is slightly compressed along one O-Fe-O axis. The [FeBr(3)(CO)(3)](-) anion has point symmetry 1 and mean bond lengths of Fe-Br = 2.455 (5) Å and Fe-C = 1.809 (2) Å. The cati...

A layer-by-layer technique has been developed to synthesize FeOOH-Au hybrid nanorods that can be transformed into Fe(2)O(3)-Au and Fe(3)O(4)-Au hybrid nanorods via controllable annealing process. The homogenous deposition of Au nanoparticles onto the surface of FeOOH nanorods can be attributed to the strong electrostatic attraction between metal ions and polyelectrolyte-modified FeOOH nanorods....

In the case of mixed-valence systems whose spin states are situated in the spin crossover region, new types of conjugated phenomena coupled with spin and charge are expected. From this viewpoint, we have investigated the multifunctional properties coupled with spin, charge and photon for the organic-inorganic hybrid system, A[Fe II Fe III X3](A = (n-CnH2n+1)4N, spiropyran; X = dto(C2O2S2), tto(...

A new probe-chelator PET dyad was synthesised, which can be used to detect Fe(3+)via fluorescence enhancement to discriminate between Fe(2+) and Fe(3+)via Fenton chemistry involving hydrogen peroxide. This is the first BODIPY which works as a 2 : 1 multiplexer for Fe(3+), Fe(2+) and H2O2.

Introduction: Iron redox systematics of the high FeO shergottitic liquids are poorly known, yet have a fundamental control on stability of phases such as magnetite, ilmenite, and pyroxenes [1]. Experiments: We undertook experiments to constrain the Fe 3+ /Fe(tot) in high FeO glasses as a function of fO2, melt P2O5, temperature and pressure. We also performed a series of sub-liquidus experiment ...

Mycobacterium tuberculosis and M. avium complex (MAC) enter and multiply within monocytes and macrophages in phagosomes. In vitro growth studies using standard culture media indicate that siderophore-mediated iron (Fe) acquisition plays a critical role in the growth and metabolism of both M. tuberculosis and MAC. However, the applicability of such studies to conditions within the macrophage pha...

Application of Magnetic Nanoparticles (MN) has emerged as a potential mode of hyperthermia, a modality for cancer therapy, in which temperature of a tumor is increased beyond physiological temperature up to 40-43 °C. We have prepared Fe 3 O 4 magnetic nanoparticles (Fe 3 O 4 -MN), which were surface-functionalized with polyethylene glycol (Fe 3 O 4 -PEG-MN) and oleic acid (Fe 3 O 4 -OAMN) to ma...

In e-commerce environments, the trustworthiness of a seller is utterly important to potential buyers, especially when the seller is unknown to them. Most existing trust evaluation models compute a single value to reflect the general trust level of a seller without taking any transaction context information into account. With such a result as the indication of reputation, a buyer may be easily d...

Reaction of the mononuclear Ni(II) thiolate complexes [Ni(L)] [L, L(1), H2L(1), bis(2-mercaptoethyl)-1,2-dimercaptoethane; L(2), H2L(2), N,N'-dimethyl-N,N'-bis(2-mercaptoethyl)-bis(aminoethyl)sulfide] with [FeCp(CO)2I] gives the dithiolate-bridged heterobimetallic species, [Ni(L(1))FeCp(CO)]PF6, 1, and [Ni(L(2))FeCp]I, 2, respectively. Binding of a Fe(CO)3 fragment via reaction of square-planar...
