Special Issue Information

Dear Colleagues,

This issue “Electrochemical Interfaces and Electrodeposition” contains a set of invited papers commissioned to celebrate the career of Maria Luisa Foresti following her retirement. Prof. M.L. Foresti received her degree in Chemistry in 1969, became an Assistent professor in 1970 and Associate Professor in 1980. She has been a full professor of Physical Chemistry at the University of Florence since 2004. Her scientific activities have covered a range of topics, all in the field of Electrochemistry, with a particular emphasis on interfacial phenomena, such as the specific adsorption of reactants and products on electrode surfaces, as well as the adsorption of organic electroinactive species and inorganic ions. Those investigations were initially carried out on liquid electrodes such as mercury and gallium, and subsequently on silver single crystals, in order to stress the important role played by the electrode surface structure. An important part of those investigations since the early 1970s concerned development of electrochemical techniques leading to computerization, both conventional and non-conventional. The understanding of interfacial phenomena observed while modifying electrode surfaces, led to research in the field of nanomaterials formed using electrochemical procedures; among them, organic monomolecular films arising from two-dimensional transitions that occur in the reorienting of electroinactive surfactants adsorbed at electrode surfaces. Increasing interest in this research field was due to the fact that ordered two-dimensional organic films impart special characteristics to metallic substrates, ranging from enhanced catalytic behavior to high corrosion resistance. Her present research activities have focused on the growth of compound semiconductors using Electrochemical Atomic Layer Epitaxy (ECALE), for the growth of new materials for photonics, sensors and energy conversion. Her research activity has been documented in over 120 papers in leading journals, together with numerous presentations at international meetings, many as an invited speaker. Her studies of the formation of ultrathin films of compound semiconductors has led to numerous national and international collaborations, with Institutions such as the University of Ulm (Germany), the University of Georgia (Athens, USA) and with the European Synchrotron Facility (ESF) in Grenoble.

The aim of this special issue is to bring together researchers worldwide in an effort to create a state-of-the-art summary of recent developments in our understanding of the science and technologyof electrochemistry and electrodeposition.

Open AccessArticle New Method of Pulsed Electrodeposition of Nanostructure of ZnS Films

The voltammetry method of analysis is used to investigate the electrochemical behavior of zinc(II) and thiosulfate (\(\text{S}_{2}\text{O}_{3}^{2-}\)) ions in acidic solutions and their electrochemical deposition onto glass coated with a conductive layer of tin oxide. It is found that electrodeposition conducted according to the two-electrode scheme using the pulse current generated by the industrial alternating current produces sound zinc sulfide deposits. Physical and chemical properties of obtained zinc sulfide films have been characterized by using scanning electron microscope and UV spectroscopy. The "cross-section" method is used to determine the thickness of zinc sulfide film, which is equal to 140–160 nm. The obtained films have n-type conductivity. Full article

In this work, a series of mono-and multilayer coatings were considered. They consisted of CrN and Cr prepared by physical vapor deposition with a cathodic arc. The most common steels for molds of plastics were chosen as substrates: X37CrMoV5-1 (SMV3), X2NiCoMo18-8-5 (MARVAL M1), X105CrCoMo18-2 (N690) and X40CrMo15 (X13T6). The samples were made with surface state conditions reproducing the main finishes required for molding of plastics: mirror, electro-eroded, sandblasted and ground finish. The coatings were characterized morphologically and chemically. The corrosion behavior of bare and coated steels was evaluated by electrochemical methods. Full article

Mercury-supported, self-assembled monolayers (SAMs) of the sole dioleoylphosphatidylcholine (DOPC) and of a raft-forming mixture of DOPC, cholesterol (Chol) and palmitoylsphingomyelin (PSM) of (59:26:15) mol% composition, were investigated by electrochemical impedance spectroscopy (EIS), both in the absence and in the presence of the monosialoganglioside GM1. The impedance spectra of these four SAMs were fitted by a series of parallel combinations of a resistance and a capacitance (RC meshes) and displayed on plots of ωZ′ against −ωZ″, where Z′ and Z″ are the in-phase and quadrature components of the impedance and ω is the angular frequency. A comparison among these different impedance spectra points to the formation of GM1-rich gel phase microdomains within the lipid rafts of the DOPC/Chol/PSM mixture, thanks to the unique molecular-level smooth support provided by mercury, which allows EIS to detect the protruding gel phase microdomains by averaging them over a macroscopically large area.

The fabrication of a nanoporous gold (NPG)-based catalyst on a glassy carbon (GC) support results normally in large isolated and poorly adhering clusters that suffer considerable material loss upon durability testing. This work exploits thermochemical oxidation of GC, which, coupled with the utilization of some recent progress in fabricating continuous NPG layers using a Pd seed layer, aims to enhance the adhesion to the GC surface. Thermochemical oxidation causes interconnected pores within the GC structure to open and substantially improves the wettability of the GC surface, which are both beneficial toward the improvement of the overall quality of the NPG deposit. It is demonstrated that thermochemical oxidation neither affects the efficiency of the Au0.3Ag0.7 alloy (NPG precursor) deposition nor hinders the achievement of continuity in the course of the NPG fabrication process. Furthermore, adhesion tests performed by a rotating disk electrode setup on deposits supported on thermochemically-oxidized and untreated GCs ascertain the enhanced adhesion on the thermochemically-oxidized samples. The best adhesion results are obtained on a continuous NPG layer fabricated on thermochemically-oxidized GC electrodes seeded with a dense network of Pd clusters. Full article

Electrochemical deposition methods are increasingly being applied to advanced technology applications, such as microelectronics and, most recently, to energy conversion. Due to the ever growing need for device miniaturization and enhanced performance, vastly improved control of the growth process is required, which in turn necessitates a better understanding of the fundamental phenomena involved. This overview describes the current status of and latest advances in electrodeposition science and technology. Electrochemical growth phenomena are discussed at the macroscopic and atomistic scale, while particular attention is devoted to alloy and compound formation, as well as surface-limited processes. Throughout, the contribution of Professor Foresti and her group to the understanding of electrochemical interfaces and electrodeposition, is highlighted. Full article
