.. .. HOW TO DETERMINE OXIDATION NUMBERS The determination of the oxidation number (or oxidation state) of chemical compounds can be made by following a few simple rules. 1. The oxidation numbers of an atom (an element, e.g., Fe) or the atoms in a neutral molecule must add up to ...

Using X-ray absorption spectroscopy (XAS) at the Cu L(2,3) and Co L(2,3) edges, we demonstrate that the valence state of copper in the thiospinel carrollite (CuCo(2)S(4)) is Cu(+) with a d count of Cu d(9.8). The Co has a d count of d(6.4), so that the highly cova...
Mountain uplift and erosion have regulated the balance of carbon between Earth’s interior and atmosphere, where prior focus has been placed on the role of silicate mineral weathering in CO2drawdown and its contribution to the stability of Earth’s climate in a habitable state1,2,3,4,5. Howev...
Zhu et al. [98] proposed a four-step chemical looping dry reforming (CLDR) process, as presented in Fig. 5a and b. In each stage, the iron-based OC underwent a shift in oxidation state as the reaction performed changed according to the following sequence: CLC (Fe3+→Fe2+), dry ...

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 ...
Qualitatively, the pre-GOE O2 sink flux could have declined if the mantle’s oxidation state increased over time32,36,37. The proportion of reducing gases in volcanic emissions depends inversely on the oxygen fugacity (\(f_{{\rm{O}}_{2}}\)) in their magma source region, the upper mant...
