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 ...

What is cause and what is consequence of aging and whether reactive oxygen species (ROS) contribute to this phenomenon is debated since more than 50 years. Notwithstanding, little is known about the cellular buffer and redox systems in agingSaccharomyces cerevisiae, which is a model for aging ste...
Determining the evolutionary history of mantle oxygen fugacity (fo2) is crucial, as it controls the fo2 of mantle-derived melts and regulates atmospheric composition through volcanic outgassing. However, the evolution of mantle fo2 remains controversial.
Oxidation Number:The sum of the oxidation numbers of each atom in a compound must be equal to the overall charge of the compound. By default, oxygen has oxidation state of -2. In this problem, you just need to know the charge of the cation to solve the oxidation state of vanadium....
"Oxidation" and "Oxidization" essentially refer to the same chemical process, where a substance loses electrons or increases its oxidation state, often involving oxygen. The "oxidation" being more commonly used.
These data were used to calculate oxygen fugacity (fO2) of the peridotites using the Nell-Wood calibration for the equilibrium between olivine, orthopyroxene and spinel (Wood et al. 1990) and are referenced to the fayalite-magnetite-quartz (FMQ) redox buffer. Preliminary results yield Δlog(fO2...
Stabilization of unusual oxidation states under high oxygen pressures: A challenge for the solid state chemist Due to the increase of the covalency of chemical bond versus the oxidation state and the correlations with physical properties, the stabilization of the highest oxidation states of transition...
Using multiscale modelling with classical molecular dynamics and density functional theory, we connect the decrease in long-range strain to the increased truncation of the oxidized nanocubes, while the higher short-range strain is shown to be due to surface softening from oxygen adsorption. Different...
