Therefore, an investigation was made on the oxidation behaviour of Si and Mn. Six kinds of wire containing different amounts of Si and Mn were used. Their compositions correspond to the ranges in which SiO2 of solid state (Field I) and liquid solution of FeO-MnO-SiO2 unsaturated with SiO2...
To date, the effect of oxidation state on activity remains controversial in whether higher or lower oxidation states benefit the enhancement of catalytic activity. Herein, we discover a volcanic relationship between oxidation state and hydrogen evolution reaction activity based on Os single-atom catalysts...
This would include things like PF6- and, as of v2020.09.1, ClF3, BrF3, IF3. The new allowed valence states for Cl are a good illustration of why this is problematic: we added the new valence state in order to be able to have the RDKit handle ClF3 by default. That's certainly not...

The possible passivation reactions of a carbon dimer defect by active species, such asO2, NO, andH2are investigated. It is found that an oxygen molecule can break a Si–C bond via dissociation in the triplet state and finally can produce two CO molecules from the carbon dimer defect. The ...
. The occurrence ofmanganese oxides(Lanza et al., 2016) also indicates that oxidation of Mn2+occurred, as the localized concentration of manganese requires transport in its more soluble reduced state. This record of reduced species, along with oxidation processes, indicates that the site had ...
Although it is known that soot particles are emitted in large quantities to the atmosphere, our understanding of their environmental effects is limited by our knowledge of how their composition is subsequently altered through atmospheric processing. Here
The two low-Al-Content Fe–10Al and Fe–20Al alloys experienced accelerated corrosion yet exhibited similar degradation behavior regardless of the solid or vapor state of KCl. The corrosion products consist of an outermost layer of cracked Fe 2 O 3 , overlying an intermediate region of the ...
