Changing face of electrochemistry

Over 200 years of development of modern electrochemistry was divided into five periods. Period I from the beginning up to the end of nineteenth century, Period II from 1901 to 1945, Period III from 1946 to 1965, Period IV from 1966 to 1990, and the last Period V from 1991 till the present. This division is based on (1) use of different research methods in these periods, as well as (2) different intensity and organization of research work. In each period, the main research interests were briefly characterized, followed by short discussion of the main achievements. The expected trends of future development of electrochemistry were also briefly discussed.     

Past, present and future of nucleic acids electrochemistry

Electrochemistry of nucleic acids was discovered about 40 years ago. During the first 15 years electrochemistry brought early evidence of DNA premelting and polymorphy of the DNA double helix. At present electrochemical methods working with stationary electrodes are able to detect DNA at attomol and in some cases, even at lower levels. A great progress in the development of electrochemical sensors for DNA hybridization and DNA damage achieved in recent years suggests that these sensors may soon become important tools in medicine and other areas of practical life of the 21st century.

Ions,ion pairs and inverse micelles in non-polar media

This paper begins with a review of the studies dedicated to the electrochemistry of non-polar liquids performed during last century. There is a list of dozens of liquids that have been studied, as well as variety of electrolytes. There is an overview of 13 different experimental methods which have been employed for this task. The theoretical part of the review emphasizes the work done by Onsager, Debye, Fuoss, Kraus, Bjerrum and others in 1920s and 30s. They initiated and justified the fundamental ideas that serve as the scientific basis for modern handbooks on non-aqueous electrochemistry. Many of these papers from 1930s and later are reviewed here.The second part of this paper is dedicated to the electrochemistry of non-polar liquids containing surfactants. These substances can serve as electrolytes if ionic. However, their main function is to enhance the solvation of ions, providing steric stabilization that minimizes ion re-association and ion-pair formation. Consequently, the classical “dissociation model” requires some modification when applied to surfactant solutions. There are also two additional theoretical models suggested specifically for surfactant solutions in non-polar liquids: the “disproportionation model” for dry inverse micelles, and the “fluctuation model” by Eicke, Borkovec, and Das-Gupta for microemulsions. Charged microemulsion droplets can serve as ions, which justifies the inclusion of this theory in this review. In addition, we can study (with a well defined theory) the transition from microemulsion droplet to dry inverse micelle ion by reducing water content. Studying this transition reveals some important features of both systems.We present here these three theories and apply them for interpreting experimental data (mostly conductivity) in four different systems, all of which are non-polar systems containing surfactants: solutions of ionic surfactants, solutions of non-ionic surfactants, microemulsions with ionic surfactants, and microemulsions with non-ionic surfactants.     

Dating Archaeological Strata in the Magna Mater Temple Using Solid‐state Voltammetric Analysis of Leaded Bronze Coins

The application of solid state electrochemistry techniques for dating archaeological strata using lead‐containing bronze coins is described. The proposed methodology was applied to samples coming from the Roman archaeological site of Magna Mater Temple (Rome, Italy) occurring in different strata dating back between the second half and the end of the 4^th century A.D. and the 20^th century. The voltammetric signatures of copper and lead corrosion products in contact with aqueous acetate buffer, as well as the catalytic effects produced on the hydrogen evolution reaction, were used for establishing the age of different strata and dating coins belonging to unknown age. Voltammetric data were consistent with a theoretical approximation based on a potential rate law for the corrosion process.     

Carbon Paste Electrodes in Facts,Numbers, and Notes: A Review on the Occasion of the 50‐Years Jubilee of Carbon Paste in Electrochemistry and Electroanalysis

This article reviews the electrochemistry and electroanalytical applications of carbon paste‐based electrodes, sensors, and detectors on the occasion of the half‐of‐century anniversary since the discovery of carbon paste. The review (with 333 references) has been prepared in the form of a retrospective compilation presenting the field by means of various facts, notes, data, surveys, and summaries, including numerous rarities or curiosities that illustrate the individual achievements and milestones. Carbon paste‐based electrodes are discussed in their entirety by covering all important areas of the field, starting from basic characterization of carbon paste as the electrode material, via its typical physicochemical and electrochemical properties or specific features, up to a representative documentation of their applicability in electrochemical and electroanalytical measurements.     

Switching “on and off” faradaic electrochemistry at an otherwise passivated electrode using gold-coated magnetic nanoparticles

Herein we combined the use of self-assembled monolayer (SAM) modified electrodes and gold coated magnetic nanoparticles (Au@MNPs) to modulate faradaic electrochemistry when nanoparticles are absorbed on and removed from, a passivated electrode using an external magnetic field. Substantial faradaic electrochemistry of potassium ferricyanide in solution is first prevented by modifying gold electrodes with 11-mercaptoundecanoic acid to form a passivating SAM. Restoration of the faradaic electrochemistry is then achieved by introducing Au@MNPs which are brought to the surface using an external magnetic field. The faradaic electrochemistry can again be suppressed by removing Au@MNPs from the SAM using another external magnetic field.
