Martian rocks, which record fO2 values intermediate between those recorded by rocks from the Moon and Earth, may have apatite that contains only S2 or mixtures of S6 and S2. Here, we present new measurements of the oxidation state of sulfur in apatite grains in the basaltic...
terminal electron acceptors such as oxygen, nitrate, or oxidized metals. Sulfide is a known phytotoxin, and its belowground oxidation is considered a detoxifying reaction for plants inhabiting coastal marine ecosystems19. Based only on amplicon sequencing of the 16S rRNA gene, sulfur oxidation coupled...
In order to assign oxidation numbers to atoms, we need to follow a set of rules. This video cannot be played because of a technical error.(Error Code: 102006) 1. The oxidation number of an element in its free state is zero. Example: The oxidation number of Zn, Al, H2, O2, and Cl...
of the absorbing solution continuously, an oxidation controlling method which comprises detecting a first deviation signal between the oxidation-reduction potential of the absorbing solution and the oxidation-reduction potential of the absorbing solution in a completely oxidized state and controlling the ...
The solubility and oxidation state of these metals is determined by cloud liquid water content, source, and sunlight. By including metal-catalyzed S(IV) oxidation, the model is consistent with the Δ17O magnitudes in the Alert data during winter. Globally, we find that this mechanism ...

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 ...
Fabrication Methods of Porous Carbon Materials and Separator Membranes for Lithium–Sulfur Batteries: Development and Future Perspectives Lithium–sulfur batteries (Li–S batteries) have a five times higher energy density than state-of-the-art lithium-ion batteries and have attracted world-wi...

High oxidation states of iron in biological and biomimetical systems: Complementary Mössbauer, EPR and magnetic susceptibility studies Compound I and compound II of heme peroxidases represent high-valent iron complexes with iron in the formal oxidation state IV. Reliable information about ... E Bill...
The oxidation of sulfur dioxide (SO2) in the presence of activated carbon particles has been studied experimentally in slurries of both pure water and sulfuric acid solutions. In the water slurries, the oxidation of absorbed molecular SO2 is accompanied by parallel oxidation of HSO3 ions produced ...
