Hydrogen permeation tests on ferritic stainless steels indicated that hydrogen can diffuse through the alloys, though the permeation was drastically decreased by formation of chromia scale on the alloys. - The mechanisms by which the presence of hydrogen or protons at the air side affects the oxide scale structure and growth are not clearly understood at this time. Several mechanisms have been proposed to tentatively explain the observed anomalous oxidation behavior. ... 

In Wei et al. s work,51 after 7 days of oxidation at 750°C, a relatively thick layer ft-5-1 Opm) of Cr-rich oxide formed under the Co-Mn and Cu-Mn spinel layers. Although such thick chromia scales are likely vulnerable to break down in long term or at higher temperatures, no anomalous oxidation behavior was reported. Similarly, in Deng et al. s work55 from the same research group, 5-7-pm-thick Cr-rich oxides formed under the Co spinel layer. 

Anomalous oxidation products are observed from the oxidation of tetraalkylborate salts (i.e. Li(R2-9-BBN)), which produces bicyclo[3.3.0]octan-l-ol as a co-product through a skeletal rearrangement which occurs during the oxidation process. Moreover, the alkaline hydrogen peroxide oxidation of l,l-di-9-BBN derivatives gives primary alcohols rather than aldehydes because of their solvolysis prior to oxidation. ...

HTPP, Figure 1) and its many 5-hydroxylated indolic metabolites might also be potential candidates for anomalous oxidation reactions leading to neurotoxic species. 

While it is too early yet to speculate about the relationship of our electrochemical results to the etiology of mental illnesses, it is quite clear that CNS indoles are very easily oxidizable compounds. In addition their oxidation chemistry is extraordinarily rich and has already been shown to yield neurotoxic products. Thus, the rather wild suggestions that anomalous oxidation chemistry of 5-HT might be an underlying cause of mental illnesses certainly appears reasonable on the basis of our, admittedly, preliminary experimental results.
