TL;DR: In this article, chemical compounds of orange peel extracts were identified and their antioxidant activities were determined by electrochemical methods, and the inhibiting effect on acidic steel corrosion brought by the extract and selected antioxidant compounds (neohesperidin, naringin, ascorbic acid) was evaluated separately by electrochemically methods.

TL;DR: In this paper, the anodic films contain defects related to the size and composition of the intermetallic phases precipitated within the aluminium matrix, and the electrochemical resistances of both the porous and the barrier layer are reduced in presence of defects, depending on their size.

TL;DR: In this paper, the initial stages of anodic layer growth in KOH-based electrolytes are studied up to and beyond the initiation of the micro-arc regime and the properties of the first anodized film preceding the occurrence of the dielectric breakdown are mainly determined by the incorporation of additives (fluorides or silicates) in the film, as shown by in situ electrochemical measurements.

TL;DR: In this paper, the authors report on experimental results on the ageing of a usual PEO electrolyte and its effect on the oxidation of the Al2214 aluminium alloy, showing that the transition from arc to soft regime occurs earlier (from 18min to 13min processing time) as the electrolyte gets older.

TL;DR: In this article, in-situ electrochemical impedance spectroscopy measurements are performed at high voltage (up to 80 V) and show that the dielectric breakdown occurs for a threshold capacitance at the electrochemical interface.
