Next, the Fe concentration in (Mn,Fe)O and (Mn,Cr,Fe) 3 O 4 as a function of oxygen partial pressure in a Fe–1.9 at.% Mn–1.6 at.% Cr alloy system at equilibrium is computed with a thermodynamic tool . Then, the estimated amount of excess oxygen consumed by Fe at each depth is obtained, considering that the concentration ratio of MnO to MnCr 2 O 4 is 3:2; see above. Figure 7 b shows the ...
Children with attention deficits concentrate better …
After each walk, concentration was measured using Digit Span Backwards. RESULTS: Children with ADHD concentrated better after the walk in the park than after the downtown walk (p = .0229) or the neighborhood walk (p = .0072). Effect sizes were substantial (Cohens d =.52 and .77, respectively) and comparable to those reported for recent formulations of methylphenidate. CONCLUSION: Twenty ...
Effect of Fe Concentration on Fe-Doped Anatase …
Figure 5 shows the relationships between ... increases with an increase in Fe concentration due to the contribution from the lower Fe 3d band, which benefits the hole mobility in VB. As a result, the electron transition energy from the valence band to the conduction band decreases as a result of Fe-doping, which may induce a red shift at the edge of the optical absorption range. In addition ...
