Research ArticleOpen accessPhrase in the titleComparative Study by Electrochemical Impedance Spectroscopy (EIS) On The Corrosion Resistance of Industrial and Laboratory Zinc CoatingsY. Hamlaoui, F. Pedraza, L. TifoutiIn this work, corrosion monitoring of Zn-based coatings is investigated through potentiodynamic and electrochemical impedance spectroscopy (EIS) methods. The first part of the study is devoted to galvanised coatings conventionally manufactured in the industry. The second part focuses on the corrosion resistance of a laboratory-made electrolytic coating. For such purpose, the corrosion behaviour is studied in NaCl media under various … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,594 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAn Electrochemical Investigation of the Redox Properties of Murexide in Aqueous and Non-Aqueous MediaHossnia S. MohranKnowledge of solvent effects on the redox properties of Murexide (Mu) is important for understanding its role as an electron acceptor in analytical and inorganic chemistry. In the present study, an investigation of the electrochemical behavior of the compound by both Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS) in both aqueous and non-aqueous solutions was undertaken. It is suggested … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,738 accessesView PDF Cite
