Electrochemistry is the branch of chemistry that deals with the chemical action of electricity and the production of electricity by chemical reactions. In a world short of energy sources yet long on energy use, electrochemistry is a critical component of the mix necessary to keep the world economies growing. Electrochemistry is involved with such important applications as batteries, fuel cells, corrosion studies, hydrogen energy conversion, bioelectricity. Research on electrolytes, cells, and electrodes is within the scope of this old but extremely dynamic field.

Whether pH is being used to test a sample against a legal requirement or specification; as part of an analytical method; for monitoring and controlling a reaction; as a process control in the chemical industry; or for the environmental monitoring of waste and effluents, it is important that all pH measurements are carried out in a logical and consistent manner, paying careful attention to experimental procedures, in order to obtain reliable results. This guide provides scientists with the knowledge of how to do just that, first by outlining the principles of pH measurement and buffer solutions. pH meters and electrodes are then discussed, including selection criteria and the care of electrodes. Finally, sections on making pH measurements and uncertainty are followed by a set of practical exercises. Measurement of pH is one of the Practical Laboratory Skills Training Guides, a series that aims to make achieving best practice easy. These invaluable manuals will enable both experienced and inexperienced staff to get the essential basics of any experiment right simply by following the clear and easy to use instructions provided. The guides are written by experienced scientists and include minimal theory, plenty of practical exercises in order to assess competence, and trouble shooting information. Other titles are: Measurement of Mass; Measurement of Volume; High Performance Liquid Chromatography; and Gas Chromatography.

This book describes, for the first time in a modern text, the fundamental principles on which solid state electrochemistry is based. In this sense it is in contrast to other books in the field which concentrate on a description of materials. Topics include solid (ceramic) electrolytes, glasses, polymer electrolytes, intercalation electrodes, interfaces and applications. The different nature of ionic conductivity in ceramic, glassy and polymer electrolytes is described as are the thermodynamics and kinetics of intercalation reactions. The interface between solid electrolytes and electrodes is discussed and contrasted with the more conventional liquid state electrochemistry. The text provides an essential foundation of understanding for postgraduates or others entering the field for the first time and will also be of value in advanced undergraduate courses.

Each chapter in this volume provides comprehensive coverage of a subject area, including detailed descriptions of techniques, derivations of fundamental equations, and discussions of important related articles. The primary topics include: Nanoscale scanning electrochemical microscopy Electrochemical applications of scanning ion conductance microscopy Electrode surface modification using diazonium salts Each volume in the series provides the necessary background and a starting point for graduate students undertaking related research projects. They are also of particular interest to practicing analytical chemists concerned with learning and applying electroanalytical techniques and the fundamental theoretical principles upon which these techniques are based.

Over the last three years, there has been an increase in the range of ionic liquids utilised and significant advances in our understanding of the fundamental aspects of these materials. Therefore, the time is apt for Faraday Discussions to provide a foundation for future fundamental challenges and theories that need to be developed to move the subject area forward. This meeting follows on from Faraday Discussion 154 held in 2011 and discusses a range of topics, such as ionicity, structure, electrochemistry, phase behaviour, and introduce areas which were only emerging at that point, such as interactions with liquid and solid interfaces. Ionic liquids have been the focus of intense research over the last 20 years because of their remarkable potential for applications coupled to favourable environmental properties. Ionic liquids are also a medium whereby the nature of the complex interactions (Coulombic, van der Waals and hydrogen bonding) provides a liquid whose structure and properties can be tuned by the choice of the cation and anion wherein reactions are likely to be distinct in terms of activity and selectivity profiles compared with common molecular solvents.

There is great interest in converting electricity overcapacity e.g. from renewables; from fuels such as hydrogen and synthetic gasoline; or for the conversion of nitrogen to ammonia. Solid oxide electrolysis offers a high efficiency route to these conversions utilising technology similar to solid oxide fuel cells. However, there are significant differences between electrolysis and fuel cell operation, and the fundamental aspects of electrolysis have received little attention. This Faraday Discussion brings together the research of leading scientists to address the fundamental aspects of solid oxide electrolysis. Research in this field could yield a new clean chemical industry, potentially allowing greater harvesting of renewables by storing excess energy in a more useful and higher energy density form than electricity.

Electrochemical methods of chemical analysis have been widely used for many years, most especially the trusty pH electrode and conductivity meter, but also in the mass-manufactured glucose test strips which place electrochemical measurements into the hands of non-scientists. The purpose of this volume is to address advances that will enable new measurement strategies in the future. Surveying research and development advances based on new methods, materials and devices that achieve improved electroanalytical performances, this collection encompasses chip-based systems, through nanodomain approaches and soft interfaces. This book is a vital resource for graduate students and professional analytical chemists.

Investigating the relationship between the magnetic properties and structure of molecules, molecular magnetochemistry, is an area of growing interest to scientists in a variety of fields, including physical, organic and inorganic chemistry, molecular physics, and biophysics.
For the first time, systematic results on magnetic properties of molecules such as mean magnetic susceptibility, their anisotropies and principal magnetic axes are presented. Molecular Magnetochemistry is a comprehensive and up-to-date view on experimental methods not covered in previous volumes, including the Zeeman effect in vapor phase and magnetic birefringence of diamagnetic systems (Cotton-Mouton Effect). The relationship between magnetic and related electrical phenomena is also described, summing up experimental data on magnetic and electrical anisotropies and components of molecular quadrupole moments.

During his distinguished scientific career, Alfred Saupe made important contributions to liquid crystal research, laying the groundwork on which much of the current knowledge and research in the physics of liquid crystals is based. This volume features papers presented by Prof. Saupe's colleagues, students and friends at a festschrift in honor of his 70th birthday. In addition, a selection of Prof. Saupe's articles are reprinted in the original German and in English translation, offering the reader a unique opportunity to see both the early work of this important scientist and widespread effect of that work on later discoveries in liquid crystal physics.

Laser photoelectron emission not only allows investigation of interfaces between electrodes and solution, but also provides a method for fast generation of intermediate species in the vicinity of the interface and so permits study of their electrode reactions. Laser Electrochemistry of Intermediates presents the first-ever comprehensive review of this important phenomenon and its electrochemical applications.
The book explores how the innovative method of laser electron emission from metal electrodes resolves two fundamental problems inherent in current methods of intermediate species (IS) generation and detection: difficulty generating IS quickly in the vicinity of the electrode surface and low IS surface concentration. In addition, for the first time, quasi-free and solvated electrons, hydrogen atoms, simple organic and inorganic radicals, and ions with anomalous valence are systematically studied.
Laser Electrochemistry of Intermediates incorporates a unique, two-pronged analytical approach. First, the authors consider the kinetics and thermodynamics of the processes based on the participation of IS in its one-electron stages, thus allowing the assignment of real physical meaning to the electrochemical measurables. Second, they consider electrode reactions side by side with homogeneous reactions of electron transfer, facilitating understanding of the universal theory of electron transfer reactions in polar media as well as the peculiarities of these reactions occurring in the interface between electrode and solution.

Chemists increasingly apply electrochemical methods to the investigation of their systems, in particular towards a better understanding of molecular properties, the exploration of chemical reactions involving electron-transfer (ET), the initiation of further reactions by ET, the kinetic measurements, and the establishment of the reaction mechanisms, as well as the synthesis (electrosynthesis) of desired products. Trends in Molecular Electrochemistry presents recent research on procedures in molecular electroactivation and electrocatalysis, bioelectrochemistry, spectroelectrochemistry, and unconventional electrochemistry. The book highlights the state-of-the-art in the application of electrochemistry by taking an interdisciplinary approach to the study of both static and dynamic molecular properties of coordination compounds as well as inorganic, bioinorganic, and organometallic complexes, supramolecular systems, and metalloenzymes. The principles and approaches are often also valid for organic systems, which are illustrated in various contexts.
