(a) Minerals with high oxidation, clay with iron oxide (Arc + FeOx
All catalysts were characterized electrochemically before and after modification with FeOx by measuring their characteristic CVs in 0.5 M [H.sub.2]S[O.sub.4] (Figure 1), where the corresponding real surface areas of the FeOx/Pt catalysts could be estimated assuming a reference value of 210[micro]C x [cm.sup.-2] for [H.sub.ads/des] .
In addition, the modification of the Pt substrate with FeOx enriches the surface with hydroxyl groups that boost the indirect dehydration pathway of FAO .
The nine OxS parameters (hydroperoxides, AOPP, RAP, thiols, uric acid, homocysteine, paraoxonase, arylesterase, and total FeOx) were evaluated as possible LOAD predictors, using simple logistic regression models.
Table 1 provides a summary of the sociodemographic, lifestyle, health status, and serum parameters of OxS (hydroperoxides, AOPP, RAP, thiols, uric acid, homocysteine, paraoxonase, arylesterase, and total FeOx) of the study sample (n =174).

Third, I examined the importance of hydrous iron oxides (FeOx
), a common soil mineral phase known to have strong sorptive capacity, for soil OM storage using a wider range of mineral soils spanning eight soil orders.
