Book Description
The dissertation consists of the following three sections: (1) Hydroxyapatite (HA) coatings. In this work, we deposited HA precursor films from weak basic electrolytic solution (pH= 8-9) via an electrochemical approach; the deposits were changed into crystallite coatings of hydroxyapatite by sintering at specific temperatures (600-800°C). The formed coatings were mainly characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). XRD patterns show well-defined peaks of HA when sintered under vacuum conditions. FTIR measurements indicate the existence of hydroxyl groups, which were confirmed by the characteristic intensity of the stretching and bending bands at ∼3575 and ∼630 cm-1, respectively. The SEM shows an adhesive, crack free morphology for the double-layer coating surface of the samples sintered in a vacuum furnace. (2) Silver/polymer/clay nanocomposites. Silver nanoparticles were prepared in layered clay mineral (montmorillonite)/polymer (PVP: poly (vinyl pyrrolidone)) suspension by an electrochemical approach. The silver particles formed in the bulk suspension were stabilized by the PVP and partially exfoliated clay platelets, which acted as protective colloids to prevent coagulation of silver nanoparticles together. The synthesized silver nanoparticles/montmorillonite/PVP composite was characterized and identified by XRD, SEM, and TEM (transmission electron microscopy) measurements. (3) Ce-doped lead zirconate titanate (PZT) thin films. In this study, we fabricated cerium-doped PZT films (molar ratio of Zr/Ti:: 0.5:0.5) via cathodic electrodeposition on the indium tin oxide (ITO) coated glass substrate. In the preparation process, the PZT films were modified by adding a small amount of cerium dopants, which led to the formation of Ce-doped PZT films after sintering at high temperatures. The fabricated PZT films on the ITO coated glass substrate may be used as electro-optic devices in the industrial application.

Book Description
Electrochemical synthesis of inorganic compounds is a relatively unknown field. The successful, large industrial processes, such as chlorine-caustic production, are well known, but the large number of other compounds that have been synthesized electrochemically are much less appreciated, even by electrochemists and inorganic chemists. The last comprehensive book on this subject was published in the 1930's and no modern review or summary of the whole field is in existence. But the field is in no way dormant, as attested by the large number of publications, undiminished throughout the years, describing new syntheses and improvements of old ones. Indeed, it can be expected that practical applications of electrochemical inor ganic syntheses will increase in the future as an increasing portion of our energy will be available in electrical form. Electrochemical processes have important advantages over chemical routes: often the selectivity of the reaction can be better controlled through the use of potential control at the electrode, and the creation of environmen tally harmful waste material can be avoided more easily since one is using the purest reagent - the electron. In addition to development of new synthetic routes, many old ones, which were found to be un economical in the past, are worth reexamining in light of the recent considerable advances in cell design principles, materials of construc tion, and electrode and separator materials, together with our im proved understanding of electrode reactions and electrocatalysis. It is in the hope of accelerating this process that this bibliography is published.

Book Description
The author provides a unified account of the electrochemical material science of metal chalcogenide (MCh) compounds and alloys with regard to their synthesis, processing and applications. Starting with the chemical fundamentals of the chalcogens and their major compounds, the initial part of the book includes a systematic description of the MCh solids on the basis of the Periodic Table in terms of their structures and key properties. This is followed by a general discussion on the electrochemistry of chalcogen species, and the principles underlying the electrochemical formation of inorganic compounds/alloys. The core of the book offers an insight into available experimental results and inferences regarding the electrochemical preparation and microstructural control of conventional and novel MCh structures. It also aims to survey their photoelectrochemistry, both from a material-oriented point of view and as connected to specific processes such as photocatalysis and solar energy conversion. Finally, the book illustrates the relevance of MCh materials to various applications of electrochemical interest such as (electro)catalysis in fuel cells, energy storage with intercalation electrodes, and ion sensing.

Book Description
The use of electrochemical techniques by chemists, particularly those who regard themselves as "inorganic" coordination chemists, has undergone a very rapid growth in the last 15-20 years. The techniques, as dassically applied to inorganic species, had their origins in analytical chemistry, and the methodology had assumed, until the mid 60s, more importance than the chemiStry. However, the growth of interest in coordination compounds (including organometallic complexes) having unusually rich of electron-transfer in bio-inorganic redox properties, and in the understanding species, has propelfed electro-chemistry into the foreground of potentially readily available techniques for application to a very wide range of problems of interest to those chemists. This growth has been fuelled additionally by the availability of relatively cheap equipment of growing sophistication and by an increase in the "inorganic" chemists' general knowledge of physical electrochemistry. In particular, with increasing availability and sophistication of eqUipment, kinetic problems are now being addressed, and the range of electrode types and configuration and solvents has been greatly expanded. Furthermore, the rapid expansion of interest in biological problems has opened new avenues in functionalisation of electrodes, in the development of sensory devices and, in a sense, a return to the analytical base of the science, using novel and multi-disciplinary techniques drawing on synthesis chemistry of and electronic micro-engeneering. The drive towards increasing use microcomputer-controlled data analysis and the development of microeledrodes has opened exciting new avenues for the exploration of chemical reactions involving electron-transfer processes.

Book Description
In recent years, great focus has been placed upon polymer thin films. These polymer thin films are important in many technological applications, ranging from coatings and adhesives to organic electronic devices, including sensors and detectors. Electrochemical polymerization is preferable, especially if the polymeric product is intended for use as polymer thin films, because electrogeneration allows fine control over the film thickness, an important parameter for fabrication of devices. Moreover, it was demonstrated that it is possible to modify the material properties by parameter control of the electrodeposition process. Electrochemistry is an excellent tool, not only for synthesis, but also for characterization and application of various types of materials. This book provides a timely overview of a current state of knowledge regarding the use of electropolymerization for new materials preparation, including conducting polymers and various possibilities of applications.
