Oxidation Number: An element's oxidation number is the charge that results when an atom of that element either gains or loses electrons. Generally speaking, metals lose electrons, and nonmetals gain electrons. Chromium (Cr) is a transition metal. ...

The Gibbs free energy of Reaction 4 is a negative number, which indicates the feasibility of this reaction. As talked above, for the Cr coating oxidized at 1200 oC for 4 h, the layers from outer to inner are Cr2O3, Cr(outer), ZrO2(outer), ZrCrFeO, Zr(Cr, Fe)2, Cr(inner)...
The increase in catalyst concentration increased the number of reactive sites and enhanced the light absorption for photocatalysis [151]. The higher concentrations of the catalyst may result in light-scattering and screening effects due to high opacity caused by an excess catalyst which compromised ...
worth noting that this and a growing number of studies consistently linked CaMKII activity to inflammation16,44,45,46,47,48,49,50. Inflammation is a central feature of aging60, our finding that CaMKII oxidation can drive inflammatory gene expression suggests that ox-CaMKII might be a direct ...
