Special Issue "Electrochemical Techniques and Methods for Materials Analysis"
Deadline for manuscript submissions: 28 February 2021.
Interests: electroanalysis; modified electrodes; adsorption; nanopowders; general analytical chemistry
Electrochemical methods and techniques for chemical composition analysis and for measuring various parameters of materials have been known and utilized for many years. They provide essential information useful in various areas of materials applications. In the scope of chemical analysis, they require (with a few exceptions) the sample to be in the form of conducting liquid, which allows to achieve an accuracy and precision unavailable for other methods. On the other hand, processes of the solid dissolution/digestion cause averaging of chemical information and loss of essential structural information, as well as information of distribution and identity of functional groups.
For applications of materials, several parameters determined by electrochemical methods are essential. The simplest—however not always easy—possibility is to monitor kinetics of various processes by means of electrochemical methods. An example of a more sophisticated application is fabrication of the electrodes from material of interest or surface/bulk modification of electrodes with such a material. Next, in performing cyclic voltammetry measurements, the kinetic parameters of an electrode reaction can be determined. By performing the potential measurement in an open circuit, several thermodynamic functions can be calculated. Parameters of electrical double layer can be assigned by measurement of differential capacity. Colloidal properties of nanopowders, nanowires, nanofims, etc., such as zeta potential, streaming potential, or Donnan potential are important examples for adsorption, and also belong to the electrochemical properties of materials.
Finally, the two methods, electrochemical impedance spectroscopy (EIS) and scanning electrochemical microscopy (SECM), provide absolutely unique information concerning materials. In the former (EIS), the application of very small alternating current perturbations allow an electrochemical cell to remain unchanged during measurement. Thus, information regarding various electrochemical processes (corrosion, charge/discharge, etc.) can be obtained. The latter method (SECM) allows for the characterization of electrochemical active sites, imaging topography, permeability and transport in the solid which is immersed in a solution. Even greater informative capability is given by coupling SECM with AFM.
This Special Issue kindly invites you to submit original research papers and reviews addressing the current progress, development, and applications of electrochemical methods for the characterization and optimization of materials.
