Noun1.oxidation state- the degree of oxidation of an atom or ion or molecule; for simple atoms or ions the oxidation number is equal to the ionic charge; "the oxidation number of hydrogen is +1 and of oxygen is -2" oxidation number ...
Magmatic oxidation statePorphyry copper depositBaogutuXinjiangThe ore-forming processes in the Baogutu porphyry copper deposit are spatially and temporally related to the Late Carboniferous intrusions in the west Junggar of China. The mineralized intrusions, consisting of granodiorite, quartz diorite, and ...
The oxidation state of Lithium (Li) is 0, and the oxidation state of Li+ is +1. Oxidation numberThe oxidation number is a positive or negative number assigned to an atom to indicate its degree of oxidation or reduction. The term oxidation state is often used interchangeably with oxidation ...
The latter case shows how the use of dispersive XANES spectroscopy allows to follow, in real time, the evolution of a system in working conditions. The simultaneous determination of the catalyst activity and of the average oxidation state of copper in the catalyst allows the evolution of a ...
Deep-ocean O2 concentrations over the past 3.5 billion years are estimated using the oxidation state of iron in submarine basalts and indicate that deep-ocean oxygenation occurred in the Phanerozoic. Oxygenation of the deep ocean associated with a rise i
desensitization of neutrophils toward MCP-1 [264,265], thereby restraining neutrophil recruitment into inflammatory tissues [266]. The mechanisms involved are not fully understood, but they appear to rely at least in part on the oxidation state of functional cysteine residues within the TRX protein ...
. The characteristic peaks of BNS are consistent with bulk B, corroborating that BNS retains the crystallinity of the original bulk B. It is worth noting that the characteristic peak of B2O3(JCPDS No. 06-0297) (Fig. S4b) appeared at about 27°, which is due to the oxidation of B. ...

by O2dissociation at the coordinatively-unsaturated Fe sites. These steps were found to be the most stable step termination when FeO/Pt(111) was exposed to O2at room temperature or above21. The evolution of the oxidation state of iron was investigated by X-ray photoelectron spectra (XPS). Up...
