Exotische Oxidationszustände der Metalle ersten Übergangsreihe haben in letzter Zeit großes Interesse geweckt. Um die Oxidationsstufen einer Reihe von Eisenoxalat-Komplexen zu untersuchen, wurde eine wässrige Lösung Eisen(III)-nitrat und Oxalsäure mittels Flüssigstrahl-Infrarot-Laser-Desorptions- Elektrospray-Massenspektrometrie untersucht. Wir zeigen, dass Eisen nicht nur seinen üblichen +II +...

The reactivity of several thiols, including glutathione, dihydrolipoic acid, cysteine, N-acetyl cysteine, and ergothioneine, as well as several disulfides, toward different redox states of myoglobin, mainly met-myoglobin (HX-FeIII) and ferrylmyoglobin (HX-FeIV=O), was evaluated by optical spectral analysis, product formation, and thiyl free radical generation. Only dihydrolipoic acid reduced me...

A new metal-organic compound, [Fe(Pydc)(DMSO)(H2O)Cl], (where Pydc is pyridine-2, 6-dicarboxylate and DMSO is dimethyl sulfoxide), has been synthesized and characterized by singlecrystal X-ray diffraction, TGA/DTA, IR and Raman spectroscopy. Green-yellow crystals,crystallized in the monoclinic system, space group P21/n, a = 7.2461(4) Å, b = 10.3018(4) Å, c =17.7667(10) Å, α = 90°, β = 90.014°(5...

Using Cr-bearing low-alloy steel is an effective preventive measure for marine structures, as it offers superior corrosion resistance when compared to plain carbon steel. However, remains unclear how quenching and tempering heat treatment, which commonly applied reinforcement in some specific environments improve its mechanical properties, affects resistance. In the present work, impact of trea...
