Book Description
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.

Book Description
Quality assurance (QA) for environmental analysis is a growing feature of the nineties as is illustrated by the number of QA guidelines and systems which are being implemented nowadays. There is, however, often a huge gap between the implementation and respect of QA guidelines and the technical approach undertaken to improve and validate new analytical methods. This is particularly true for complex determinations involving multi-step methodologies such as those used in speciation and organic analyses. Quality assurance may also be considered from the technical point of view, which is the focus of this book. The techniques used in different analytical fields (inorganic, speciation and organic analysis) are critically reviewed (i.e. discussion of advantages and limitations) and existing tools for evaluating their performance are described (e.g. interlaboratory studies, use of certified reference materials). Particular reference is made to the activities of the Measurements and Testing Programme (BCR) of the European Commission towards the improvement of quality control of environmental analysis. The book has been written by experienced practitioners. By its nature, it serves as a practical reference for postgraduate students and environmental chemists who need a wide overview of the techniques used in environmental analysis and existing ways of evaluating the performance of relevant analytical methods. The critical discussions of the methods described, as well as the development of quality assurance aspects, makes it unique.

Book Description
Battery technology is constantly changing, and the concepts and applications of these changes are rapidly becoming increasingly more important as more and more industries and individuals continue to make “greener” choices in their energy sources. As global dependence on fossil fuels slowly wanes, there is a heavier and heavier importance placed on cleaner power sources and methods for storing and transporting that power. Battery technology is a huge part of this global energy revolution. Zinc batteries are an advantageous choice over lithium-based batteries, which have dominated the market for years in multiple areas, most specifically in electric vehicles and other battery-powered devices. Zinc is the fourth most abundant metal in the world, which is influential in its lower cost, making it a very attractive material for use in batteries. Zinc-based batteries have been around since the 1930s, but only now are they taking center stage in the energy, automotive, and other industries. Zinc Batteries: Basics, Developments, and Applicationsis intended as a discussion of the different zinc batteries for energy storage applications. It also provides an in-depth description of various energy storage materials for Zinc (Zn) batteries. This book is an invaluable reference guide for electrochemists, chemical engineers, students, faculty, and R&D professionals in energy storage science, material science, and renewable energy.
