The book is an up-to-date introduction to the fundamentals of the initial stages of Electrocrystallization, which are dominated by nucleation and growth of the first clusters of the new phase. It offers a readable exposition of the topic, in simple terms, providing a detailed theoretical description of the phenomena involved. The most relevant aspects of the experimental studies of electrochemical nucleation and growth are considered, as well, including some important methods for acquiring and analyzing experimental results. Having specific properties quite different from those of bulk materials, these small, nano-clusters have always attracted considerable attention, and many sophisticated methods have been developed for cluster studies. In spite of this, information on small clusters can still be obtained by simple experiments, and the book shows that Electrocrystallization is unique in this respect. In this special case the phase change may be controlled experimentally by controlling the voltage and current, two simple and easily measurable electrical quantities. Certainly, this is what makes electrochemical systems an attractive object of study both from a scientific and from a practical point of view.

Electrochemistry plays an important role in preserving our cultural heritage. For the first time this has been documented in the present volume. Coverage includes both electrochemical processes such as corrosion and electroanalytical techniques allowing to analyse micro- and nanosamples from works of art or archaeological finds. While this volume is primarily aimed at electrochemists and analytical chemists, it also contains relevant information for conservators, restorers, and archaeologists.
Li-Co-Mn-Ni oxides have been of extreme interest as potential positive electrode materials for next generation Li-ion batteries. Though many promising materials have been discovered and studied extensively, much debate remains in the literature about the structures of these materials. There is no consensus as to whether the lithium-rich layered materials are single-phase or form a layered-layered composite on the few nanometer length-scales. Much of this debate came about because no phase diagrams existed to describe these systems under the synthesis conditions used to make electrode materials. Detailed in this thesis are the complete Li-Co-Mn-O and Li-Mn-Ni-O phase diagrams generated by way of the combinatorial synthesis of mg-scale samples at over five hundred compositions characterized with X-ray diffraction. Selected bulk samples were used to confirm that the findings are relevant to synthesis conditions used commercially. The results help resolve a number of points of confusion and contradiction in the literature. Amongst other important findings, the compositions and synthesis conditions giving rise to layered-layered nano-composites are presented and electrochemical results are used to show how better electrode materials can be achieved by making samples in the single phase-layered regions.

A battery comprises essentially three components: positive electrode, negative electrode, and electrolyte. Each component is discussed for the construction of all-solid-state Batteries. Theoretical understanding of properties of battery materials by using molecular orbital calculations is also introduced.
" Cluster Materials" is the fourth volume of the highly successful
series " Advances in Metal and Semiconductor Clusters." In this
volume the focus is on the properties of clusters which determine
their potential applications as new materials. Metal and
semiconductor clusters have been proposed as precursors for
materials or as actual materials since the earliest days of cluster
research. In the last few years, a variety of techniques have made
it possible to produce clusters in sizes varying from a few atoms
up to several thousand atoms. While some measurements are performed
in the gas phase on non-isolated clusters, many cluster materials
can now be isolated in macroscopic quantities and more convenient
studies of their properties become possible.

Given that thermodynamics books are not a rarity on the market, why would an additional one be useful? The answer is simple: at any level, thermodynamics is usually taught as a somewhat abstruse discipline where many students get lost in a maze of difficult concepts. However, thermodynamics is not as intricate a subject as most people feel. This book fills a niche between elementary textbooks and mathematically oriented treatises, and provides readers with a distinct approach to the subject. As indicated by the title, this book explains thermodynamic phenomena and concepts in physical terms before proceeding to focus on the requisite mathematical aspects. It focuses on the effects of pressure, temperature and chemical composition on thermodynamic properties and places emphasis on rapidly evolving fields such as amorphous materials, metastable phases, numerical simulations of microsystems and high-pressure thermodynamics. Topics like redox reactions are dealt with in less depth, due to the fact that there is already much literature available. Without requiring a background in quantum mechanics, this book also illustrates the main practical applications of statistical thermodynamics and gives a microscopic interpretation of temperature, pressure and entropy. This book is perfect for undergraduate and graduate students who already have a basic knowledge of thermodynamics and who wish to truly understand the subject and put it in a broader physical perspective. The book is aimed not at theoretical physicists, but rather at practitioners with a variety of backgrounds from physics to biochemistry for whom thermodynamics is a tool which would be better used if better understood.
