2.6), SoxCD catalyzes the six-electron oxidation of protein-bound sulfane–sulfur (oxidation state − 1) to sulfone–sulfur (+ 5) and electrons are transferred to small periplasmic cytochromes c. Notably, the Sox system lacking SoxCD still oxidizes sulfite, showing that SoxCD is not ...
1. The oxidation number of an element in its free state is zero. Example: The oxidation number of Zn, Al, H2, O2, and Cl2 is zero 2. The oxidation number of a monatomic ion is the same as the charge on the ion. Example: The oxidation number of Na+ is +1, Mg2+ is +2, Al...
Analysis of manganese mineral occurrences and valence states demonstrate oxidation of Earth’s crust through time. Changes in crustal redox state are critical to Earth’s evolution, but few methods exist for evaluating spatially averaged crustal redox st
This fact may be attributed to the complexity resulting from the existence of various species of chromium(VI) in acidic medium as well as the instability of CrV and CrIV oxidation states through the reduction of chromium ion from hexavalent to trivalent state. This fact may not allow a ...
Finally, low pressure exposures to air result in the adsorption of both nitrogen and oxygen onto the surface. Some of the nitrogen adsorbed on the surface at low pressures is in a reversibly adsorbed state in the sense that subsequent exposure to low pressures of O2 results in the displacement...
Dense, uniform, and well-adhered chromium (Cr) coatings were deposited on zirconium (Zr) alloy claddings by using physical vapor deposition (PVD). The Cr-coated samples were tested at 1200 oC and 1300 oC, respectively, for different exposure time i
EDTA catalyzed oxidation of iodide by chromic acid obeys first order kinetics with respect to Cr(VI) and H + and fractional order kinetics with respect to EDTA. The order in I − changes from unity to zero. The formation of a termolecular complex involving Cr(VI), EDTA and I − is...

Thermal stability and oxidation behavior of Cr2AlB2 powders were investigated at 600−1200 °C. Cr2AlB2 is stable up to 900 °C in argon, partially decomposes into Cr4AlB4 and Al at 950−1070 °C, and partially decomposes into CrB and Al at 1090−1200 °C. Oxidation in ...
