“…This is also clear confirmed from Nyquist plots, where single slightly depressed semi-circles are observed (Fig. 3(a)), which indicates that electrochemical solid/liquid interface is having non-ideal capacitive behavior 37 . Also the presence of single time constant indicates that corrosion process is mainly charge transfer controlled 38 .…”

Corrosion inhibition behavior of Ascorbic acid (AA) vitamin C and Thiamine (Th) vitamin B1 on mild steel corrosion in 0.5 M HCl was investigated at various immersion times. The electrochemical characteristics of mild steel in absence and presence of the inhibitors were verified by the cyclic voltammetry method. The protective properties of the passive film were acquired by electrochemical impedance spectroscopy. The best inhibitive performance was obtained for VitB1. The polarization curves indicated the high inhibition efficiency of the inhibitors. The existence of a protective film on mild steel was confirmed by SEM techniques. Computational chemistry was carried out to establish the mechanism of corrosion inhibition.

“…The utility and versatility of this methodology was demonstrated with LSERs for 74 MEKC systems taken from the literature, and the ensuing system selectivity cube method effectively grouped those systems exhibiting little or no difference in selectivity and those differing in it. Finally, it is worth mentioning here the models reported by Ghowsi and Ghowsi for correcting equations closely related to resolution and the number of theoretical plates in MEKC.…”

This review article addresses recent methodological and instrumental innovations in MEKC with emphasis on practical aspects. Like its predecessors, this review is intended to provide an updated overview covering work on the most salient methodological contributions to enhancing sensitivity and resolution in MEKC-based determinations published over the past two years. The most widespread approaches to enhancing sensitivity, which include improving "classical" online sample concentration techniques, combinations of on- and off-line sample concentration protocols and recent developments are discussed, and so are modifications of existing MEKC systems with various micellar phases, the use of BGE additives (organic modifiers, chiral selectors, gold nanoparticles) and coated capillaries, and the implementation of 2D separations and chemometric methods to enhance resolution. Instrumental approaches such as MS and LIF are also discussed, and proposals for overcoming the problems typically encountered in directly coupling MEKC with MS, and the recent inception of quantum dots with a great potential for LIF detection in MEKC, are also dealt with. Finally, foreseeable developments on potential future directions are also expressed.
