Anomalous dissolution of metals and chemical corrosion [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
An overview is given of the anomalous behavior of some metals, in particular Fe and Cr, in acidic aqueous solutions during anodic dissolution. The anomaly is recognizable by the fact that during anodic dissolution more material dissolves than would be ...

Anomalous photoelectrochemical etching of undoped semiconductor surfaces [PDF]

open access: yesNature Communications
For more than 60 years, it has been widely accepted that the irradiance of the incoming light plays the most critical role in the etching effect of the photoelectrochemical etching process, which is built upon the underlying physics that photo-generated ...

The role of the beta-Mg17Al12 phase on the anomalous hydrogen evolution and anodic dissolution of AZ magnesium alloys

open access: yesCorrosion Science, 2020
The role of the MgAl second phase on the anomalous HE and anodic dissolution of AZ31 and AZ91 Mg alloys was investigated. A passive-like behavior was exhibited by the MgAl phase with strong anomalous HE originating from local anodic regions where the passive film had broken down.

Transition from anomalous kinetics toward Fickian diffusion for Si dissolution into amorphous Ge [PDF]

open access: yesApplied Physics Letters, 2008
Over the last years, several experimental and theoretical studies of diffusion kinetics on the nanoscale have shown that the time evolution (x∝tkc) differs from the classical Fickian law (kc=0.5). However, all work was based on crystalline samples or models, so far.

Electrochemistry of active chromium, part III: Effects of temperature [PDF]

open access: yesJournal of the Serbian Chemical Society, 2003
It was shown that the temperature in the range 20 – 65 ºC has considerable effects on the electrochemical anodic dissolution of chromium in the active potential range as well as on the electrochemical hydrogen evolution reactions on bare and oxide ...

Electrochemistry of active chromium. Part IV. Dissolution of chromium in deaerated sulfuric acid [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
Chromium dissolution in aqueous sulfuric acid solutions in the pH range 0.5 –3 was studied electrochemically by the potentiostatic or very slow potentiodynamic method, and by the analyses of the Cr ion concentrations in the electrolyte formed during the ...

Dissolution of chromium in sulfuric acid [PDF]

open access: yesJournal of the Serbian Chemical Society, 2002
By combining electrochemical corrosion rate measurements and spectrophotometric analysis of the electrolyte it was shown that at room temperature chromium dissolves in deaerated 0.1 M Na2SO4 + H2SO4 (pH 1) solution as Cr(II) and Cr(III) ions in he ratio ...

Potential impacts of chemical weathering on feldspar luminescence dating properties [PDF]

open access: yesGeochronology, 2023
Chemical weathering alters the chemical composition of mineral grains. As a result, trapped-charge dating signals of primary silicates may be progressively modified.
