Special Issue Information

Dear Colleagues,

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.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs).
