This book provides a comprehensive review of the production of smelter grade alumina from bauxite ores. It emphasizes the best practices applied in the industry today but seen in a historical context with a view to future challenges and developments. The control of alumina quality is discussed in detail including the effects that alumina quality have on the aluminum smelter process with respect to environmental performance, current efficiency, and metal purity. The discussion of alumina quality will be relevant to people on the smelter side, as this is the interface between refinery and smelter. Emphasis is placed on the major steps of the Bayer Process including: digestion, clarification, precipitation, calcination, and management of water, energy, and bauxite residue. This book is a valuable resource for active, seasoned practitioners and for new engineers entering the industry.

Battery Management Systems - Design by Modelling describes the design of Battery Management Systems (BMS) with the aid of simulation methods. The basic tasks of BMS are to ensure optimum use of the energy stored in the battery (pack) that powers a portable device and to prevent damage inflicted on the battery (pack). This becomes increasingly important due to the larger power consumption associated with added features to portable devices on the one hand and the demand for longer run times on the other hand. In addition to explaining the general principles of BMS tasks such as charging algorithms and State-of-Charge (SoC) indication methods, the book also covers real-life examples of BMS functionality of practical portable devices such as shavers and cellular phones.

Simulations offer the advantage over measurements that less time is needed to gain knowledge of a battery's behaviour in interaction with other parts in a portable device under a wide variety of conditions. This knowledge can be used to improve the design of a BMS, even before a prototype of the portable device has been built. The battery is the central part of a BMS and good simulation models that can be used to improve the BMS design were previously unavailable. Therefore, a large part of the book is devoted to the construction of simulation models for rechargeable batteries. With the aid of several illustrations it is shown that design improvements can indeed be realized with the presented battery models. Examples include an improved charging algorithm that was elaborated in simulations and verified in practice and a new SoC indication system that was developed showing promising results.

The contents of Battery Management Systems - Design by Modelling is based on years of research performed at the Philips Research Laboratories. The combination of basic and detailed descriptions of battery behaviour both in chemical and electrical terms makes this book truly multidisciplinary. It can therefore be read both by people with an (electro)chemical and an electrical engineering background.

This book is devoted to various aspects of self-assembly of gold nanoparticles at liquid-liquid interfaces and investigation of their properties. It covers primarily two large fields: (i) self-assembly of nanoparticles and optical properties of these assemblies; and (ii) the role of nanoparticles in redox electrocatalysis at liquid-liquid interfaces. The first part aroused from a long-lasting idea to manipulate adsorption of nanoparticles at liquid-liquid with an external electric field to form 'smart' mirrors and/or filters. Therefore, Chapters 3 to 5 are dedicated to explore fundamental aspects of charged nanoparticles self-assembly and to investigate optical properties (extinction and reflectance) in a through manner. Novel tetrathiafulvalene (TTF)-assisted method leads to self-assembly of nanoparticles into cm-scale nanofilms or, so-called, metal liquid-like droplets (MeLLDs) with remarkable optical properties. The second part (Chapters 6 to 8) clarifies the role of nanoparticles in interfacial electron transfer reactions. They demonstrate how nanoparticles are charged and discharged upon equilibration of Fermi levels with redox couples in solution and how it can be used to perform HER and ORR. Finally, Chapter 9 gives a perspective outlook, including applications of suggested methods in fast, one-step preparation of colloidosomes, SERS substrates as well as pioneer studies on so-called Marangony-type shutters drive by the electric field.

Synchrotron Techniques in Interfacial Chemistry covers the structure of the electrode--solution interface and surface films, theory of X-ray scattering at surfaces and interfaces, synchrotron radiation instrumentation, surface X-ray diffraction, X-ray reflectivity, X-ray absorption spectroscopy (EXAFS and XANES), standing wave techniques, and IR spectroscopy. The use of each technique in the study of electrochemical problems is illustrated.

This book represents the first rigorous treatment of thermoelectrochemistry, providing an overview that will stimulate electrochemists to develop and apply modern thermoelectrochemical methods. While classical static approaches are also covered, the emphasis lies on methods that make it possible to independently vary temperature such as in-situ heating of electrodes by means of electric current, microwaves or lasers. For the first time, "hot-wire electrochemistry" is examined in detail. The theoretical background presented addresses all aspects of temperature impacts in the context of electrochemistry.

The first model for the distribution of ions near the surface of a metal electrode was devised by Helmholtz in 1874. He envisaged two parallel sheets of charges of opposite sign located one on the metal surface and the other on the solution side, a few nanometers away, exactly as in the case of a parallel plate capacitor. The rigidity of such a model was allowed for by Gouy and Chapman inde pendently, by considering that ions in solution are subject to thermal motion so that their distribution from the metal surface turns out diffuse. Stern recognized that ions in solution do not behave as point charges as in the Gouy-Chapman treatment, and let the center of the ion charges reside at some distance from the metal surface while the distribution was still governed by the Gouy-Chapman view. Finally, in 1947, D. C. Grahame transferred the knowledge of the struc ture of electrolyte solutions into the model of a metal/solution interface, by en visaging different planes of closest approach to the electrode surface depending on whether an ion is solvated or interacts directly with the solid wall. Thus, the Gouy-Chapman-Stern-Grahame model of the so-called electrical double layer was born, a model that is still qualitatively accepted, although theoreti cians have introduced a number of new parameters of which people were not aware 50 years ago."

Proteins are the functional units of the cellular machinery and they provide significant information regarding the molecular basis of health and disease. Therefore, techniques to separate and isolate the various proteins are critical to studying and understanding their functional characteristics. One of the widely used techniques for this purpose is electrophoresis. In Protein Electrophoresis: Methods and Protocols, contributions from experts in the field have been collected in order to provide practical guidelines to this complex study. Each chapter outlines a specific electrophoretic variant in detail so that laboratory scientists may perform a technique new to their lab without difficulty. Written in the successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Protein Electrophoresis: Methods and Protocols seeks to serve laboratory scientists with well-honed, detailed methodologies in an effort to further our knowledge of this essential field.

The thesis by Merce Pacios exploits properties of carbon nanotubes to design novel nanodevices. The prominent electrochemical properties of carbon nanotubes are used to design diverse electrode configurations. In combination with the chemical properties and (bio)functionalization versatility, these materials prove to be very appropriate for the development of electrochemical biosensors. Furthermore, this work also evaluates the semiconductor character of carbon nanotubes (CNT) for sensor technology by using a field effect transistor configuration (FET). The CNT-FET device has been optimized for operating in liquid environments. These electrochemical and electronic CNT devices are highly promising for biomolecule sensing and for the monitoring of biological processes, which can in the future lead to applications for rapid and simple diagnostics in fields such as biotechnology, clinical and environmental research.

Microelectronic Packaging analyzes the massive impact of electrochemical technologies on various levels of microelectronic packaging. Traditionally, interconnections within a chip were considered outside the realm of packaging technologies, but this book emphasizes the importance of chip wiring as a key aspect of microelectronic packaging, and focuses on electrochemical processing as an enabler of advanced chip metallization. Divided into five parts, the book begins by outlining the basics of electrochemical processing, defining the microelectronic packaging hierarchy, and emphasizing the impact of electrochemical technology on packaging. The second part discusses chip metallization topics including the development of robust barrier layers and alternative metallization materials. Part III explores key aspects of chip-package interconnect technologies, followed by Part IV's analysis of packages, boards, and connectors which covers materials development, technology trends in ceramic packages and multi-chip modules, and electroplated contact materials. Illustrating the importance of processing tools in enabling technology development, the book concludes with chapters on chemical mechanical planarization, electroplating, and wet etching/cleaning tools. Experts from industry, universities, and national laboratories submitted reviews on each of these subjects, capturing the technological advances made in each area. A detailed examination of how packaging responds to the challenges of Moore's law, this book serves as a timely and valuable reference for microelectronic packaging and processing professionals and other industrial technologists.

This volume is based on the lectures presented at the NATO Advanced Study Institute: (ASI) "Pollutants Formation from Combustion. Formation Mechanisms and Impact on th th Atmospheric Chemistry" held in Maratea, Italy, from 13 to 26 september 1998. Preservation of the environment is of increasing concern in individual countries but also at continental or world scales. The structure of a NATO ASI which involve lecturers and participants of different nationalities was thought as especially well suited to address environmental issues. As combustion is known to substantially contribute to the damaging of the atmosphere, it was natural to concentrate the ASI program on reviewing the currently available knowledge of the formation mechanisms of the main pollutants liberated by combustion systems. In most situations, pollutants are present as trace components and their formation and removal is strongly conditioned by the chemical reactions initiated by fuel consumption. Therefore specific lectures were aimed at defining precisely the general properties of combustion chemistry for gaseous, liquid and solid fuels. Physical factors can strongly affect the combustion chemistry and their influence was also considered. An interesting peculiarity of this specific ASI was to complement the program with a substantial part concerned with the impact of the main combustion pollutants: NOx, aromatics, soot, VOCs, sulphur and chlorinated compounds, on atmospheric chemistry.

In this book, the term "electrochemical nanotechnology" is defined as nanoprocessing by means of electrochemical techniques.

Some solution properties such as conformation of flexible polyions, osmotic coefficients and electrophoretic properties are addressed along with recent progress in analytical theory and simulation.

Humankind's use of zinc stretches back to antiquity, and it was a component in some of the earliest known alloy systems. Even though metallic zinc was not "discovered" in Europe until 1746 (by Marggral), zinc ores were used for making brass in biblical times, and an 87% zinc alloy was found in prehistoric ruins in Transylvania. Also, zinc (the metal) was produced in quantity in India as far back as the thirteenth century, well before it was recognized as being a separate element. The uses of zinc are manifold, ranging from galvanizing to die castings to electronics. It is a preferred anode material in high-energy-density batteries (e.g., Ni/Zn, Ag/Zn, ZnJair), so that its electrochemistry, particularly in alkaline media, has been extensively explored. In the passive state, zinc is photoelectrochemically active, with the passive film displaying n-type characteristics. For the same reason that zinc is considered to be an excellent battery anode, it has found extensive use as a sacrificial anode for the protection of ships and pipelines from corrosion. Indeed, aside from zinc's well-known attributes as an alloying element, its widespread use is principally due to its electrochemical properties, which include a well-placed position in the galvanic series for protecting iron and steel in natural aqueous environments and its reversible dissolution behavior in alkaline solutions.

This thesis systematically introduces readers to a new metal-organic framework approach to fabricating nanostructured materials for electrochemical applications. Based on the metal-organic framework (MOF) approach, it also demonstrates the latest ideas on how to create optimal MOF and MOF-derived nanomaterials for electrochemical reactions under controlled conditions. The thesis offers a valuable resource for researchers who want to understand electrochemical reactions at nanoscale and optimize materials from rational design to achieve enhanced electrochemical performance. It also serves as a useful reference guide to fundamental research on advanced electrochemical energy storage materials and the synthesis of nanostructured materials.

This volume of Modern Aspects contains seven chapters. The major topics covered in the first six chapters of this volume include fundamentals of solid state electrochemistry; kinetics of electrochemical hydrogen entry into metals and alloys; oxidation of organics; fuel cells; electrode kinetics of trace-anion catalysis; nano structural analysis. The last chapter is a corrected version of chapter four from Volume 35. Faisal M. AI-faqeer and Howard W. Pickering begin the first chapter by going back to 1864 and Cailletet who found that some hydrogen evolved and was absorbed by iron when it was immersed in dilute sulfuric acid. The absorption of hydrogen into metals and alloys can lead to catastrophic failures of structures. They discuss the kinetics of electrochemical hydrogen entry into metals and alloys. In chapter three, Clyde L. Briant reviews the electrochemistry, corrosion and hydrogen embrittlement of unalloyed titanium. He begins by reviewing the basic electrochemistry and general corrosion of titanium. He also discusses pitting and galvanostatic corrosion followed by a review of hydrogen embrittlement emphasizing the formation of hydrides and the effect of these on titanium's mechanical properties. Christos Comninellis and Gy6rgy F6ti discuss the oxidative electrochemical processes of organics in chapter three. They begin by defining direct and indirect electrochemical oxidation of organics. They introduce a model that allows them to distinguish between active (strong) and non-active (weak) anodes. Different classes of organic compounds are used for kinetic models of organic oxidation at active and non-active type anodes.

Jonathan Scragg documents his work on a very promising material suitable for use in solar cells. Copper Zinc Tin Sulfide (CZTS) is a low cost, earth-abundant material suitable for large scale deployment in photovoltaics. Jonathan pioneered and optimized a low cost route to this material involving electroplating of the three metals concerned, followed by rapid thermal processing (RTP) in sulfur vapour. His beautifully detailed RTP studies - combined with techniques such as XRD, EDX and Raman - reveal the complex relationships between composition, processing and photovoltaic performance. This exceptional thesis contributes to the development of clean, sustainable and alternative sources of energy

Nowadays, there are increasing demands for the control and specification of all aspects of industrial manufacturing. There is also a growing need to understand various biological processes and conditions for agricultural production, and concern for protection of the environment and human health. These factors have made it imperative to develop adequate methods for the analysis of gaseous substances or substances that can be converted to the gaseous state. It is not only necessary to apply known and developed methods correctly, but novel analytical procedures must also be found. Instrumentation should be improved and the applications of these methods will have to be extended.

The present volume provides a comprehensive description of the state-of-the-art and of future possibilities in the analysis of gaseous substances. In the individual chapters the following themes have been discussed; the theoretical basis for the methods, a description of the instrumentation and the steps necessary in actual analyses and an outline of the principal areas in which each method can be employed. Both classical methods that are still useful for the solution of analytical problems using simple instrumentation, and the newest methods in the field are described. Special attention is paid to modern electrochemical and spectroscopic methods, and to methods based on a number of physical principles. Gas chromatography is discussed in the greatest detail because of its specially important position in modern analytical chemistry.

The book should be well received by the analytical public and should be extremely useful to students and workers in scientific research laboratories and in fields dealing with environmental protection.

The book presents the method of thermodynamic Green Functions applied to the problems of electrochemistry. The basic theorems and their derivations are found at the didactic level which requires, however, a knowledge of the principles of quantum mechanics and statistical physics. The book is mainly based on the results of papers published during the last fifteen years by its authors and their coworkers from the Department of Theoretical Chemistry and the Department of Solid State Physics of the University ofL6di (poland) within the context of the results reported in literature. Although the Green Functions Method has become very popular in solid state physics, there are almost no applications of this technique to electrochemistry. The only papers where the Green Functions Method is applied to the molten salts and liquid mercury theory are the precursory works published by Professor S. G. Davison and his coworkers from the Waterloo University (Canada) in the early eighties. We hope that the present book can fill this gap in the electrochemical literature.
