No shift in the Cr-K edge was observed with increase in chromium content. The XAS measurements suggest that chromium exists either as +3 or +5 state in (Na _(0.5)Bi _(0.5)TiO _3) _((1-x))(BiCrO _3)x. The impedance measurements show a considerable increase in the electrical ...
Dense, uniform, and well-adhered chromium (Cr) coatings were deposited on zirconium (Zr) alloy claddings by using physical vapor deposition (PVD). The Cr-coated samples were tested at 1200 oC and 1300 oC, respectively, for different exposure time i

Determine the oxidation state of nitrogen in NO3−. Oxidation State:It is sometimes known as oxidation number, and it outlines the level of oxidation in an atom. When atoms bond with other atoms, they form chemical bonds. In the process, they either gain or lose electrons; the number of...
In recent years, some modelling efforts have focused on self-diffusion coefficients in pure Cr, Cr2O3, and Cr-containing alloys using density functional theory20,21,22,23. While each of these approaches provides its own insights on the nature of point defects’ charge state, mobility, and ...
This process is shown explicitly in Scheme 4. In this alternative pathway CrO3 is the only oxidant of the secondary alcohol. Scheme 5 shows a proposed mechanism for the conversion of H2CrO3 to Cr(OH)3 and CrO3. Sign in to download full-size image Scheme 3. Sign in to download full-...
The oxidation number of an atom in a compound or in its pure state is its charge when it becomes an ion. This is the value that is the main concern in a redox reaction. It is the one monitored because the corresponding change in this value will mean that the chemical species undergoes...
