Electrocrystallization: Fundamentals of Nucleation and Growth
Alexander Milchev Manufacturer: Springer ProductGroup: Book Binding: Hardcover ASIN: 140207090X |
Book Description
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.

Fundamentals of Solid-State Phase Transitions, Ferromagnetism and Ferroelectricity
Yuri Mnyukh Manufacturer: 1st Books Library ProductGroup: Book Binding: Hardcover Similar Items: ASIN: 0759602190 |
Customer Reviews:
Excellent book.......2001-09-23
There are many separate books on phase transitions, ferromagnetism and ferroelectricity. Neither adequately accounted for their phenomena. Inconsistencies were profound: "critical points" were "rounded" and subjected to hysteresis; "lambda-anomalies" were observed upon first-order transitions; exchange integral had wrong sign; domain structure of antiferromagnetics and ferroelectrics had no reason to exist; "critical phenomena" concept was applied to rearrangements at interfaces ...
In contrast, Mnyukh's monograph provides unexpectedly simple, consistent and unified account for all three scientific areas, clarifying everything. How this became possible? The key is his experimental discoveries, which allowed deduce the universal molecular mechanism of phase transitions in solids.
Chapter 1 "Critical Survey" reveals failures of different theories and lays out fundamental principles. There are only two ways a phase transition can occur -by infinitesimal qualitative changes (second-order) or infinitesimal quantitative changes (first-order). The only way the latter can occur is nucleation and growth. This prohibits approximation of first-order transitions by second-order ones. The second principle, well substantiated, further simplifies the picture: only nucleation and growth materializes.
Chapter 2 "The Molecular Mechanism of Solid-State Phase Transitions" describes the author's experimental findings. The most impressive is observation of beautifully shaped single crystals growing in different orientations during phase transitions. It is a crystal growth, and not a "critical phenomenon", "displacement", "shift", "deformation" or "distortion". Investigation in depth led to other discoveries and allowed deduce the contact model of phase transitions. All aspects of this crystal growth were studied. Clarification of the notion "temperature of phase transition" and the conclusion that nucleation is impossible without microcavities of a specific size led to explanation of heterophase state, range of transition, hysteresis and "lambda-anomalies".
Two more consequential results: 1.Transitions CRYSTAL-ODC (orientation-disordered crystal) occur also by crystal growth. 2. Frequently observed lattice orientation relationship originates from epitaxial nucleation and growth which was erroneously classified as second-order transition. The whole classification of solid-state phase transitions is thus reduced to only non-oriented and epitaxial crystal growth.
Chapter 3 "Lambda-Anomalies and Other Apparent Anomalies" reveals the true nature of the phenomenon that mystified scientists for so long: the peaks of some properties vs. temperature observed during phase transitions. Anderson wrote [Science, # 4574]: "Landau...nominated [the anomalies] as the most important as yet unsolved problem in theoretical physics". Feynman regarded them "one of the challenges of theoretical physics today". But an experimentalist now explains them.
Chapter 4 "Fundamentals of Ferromagnetism and Ferroelectricity" is based on the findings of previous chapters. The phenomena and their manifestations are explained in straightforward way without Weiss/Heisenberg molecular/exchange field. The account for ferroelectricity is actually the same.
The solutions presented in this book are well substantiated, logically monolithic, answering all questions left by conventional theories; they are destined to prevail.

Additives and Crystallization Processes: From Fundamentals to Applications
Keshra Sangwal Manufacturer: Wiley ProductGroup: Book Binding: Hardcover ASIN: 0470061537 |
Book Description
Crystal growth technology involves processes for the production of crystals essential for microelectronics, communication technologies, lasers and energy producing and energy saving technology. A deliberately added impurity is called an additive and in different industries these affect the process of crystal growth. Thus, understanding of interactions between additives and the crystallizing phases is important in different processes found in the lab, nature and in various industries.This book presents a generalized description of the mechanisms of action of additives during nucleation, growth and aggregation of crystals during crystallization and has received endorsement from the President of the International Organization for Crystal Growth. It is the first text devoted to the role of additives in different crystallization processes encountered in the lab, nature and in industries as diverse as pharmaceuticals, food and biofuels.
A unique highlight of the book are chapters on the effect of additives on crystal growth processes, since the phenomena discussed is an issue of debate between researchers

Direct Phasing in Crystallography: Fundamentals and Applications (International Union of Crystallography Monographs on Crystallography)
Carmelo Giacovazzo Manufacturer: Oxford University Press, USA ProductGroup: Book Binding: Hardcover ASIN: 0198500726 |
Book Description
Direct methods are, at present, applied to a large variety of cases: X-ray, neutron or electron data; single crystal and powder data; small molecules and macromolecules. While direct methods solved in practice the phase problem for small molecules, their application to macromolecules is recent and still undergoing strong development. The fundamentals of the methods are described: in particular it is shown how the methods can be optimized for powder, neutron or electron data, and how they can be integrated with isomorphous replacement, molecular replacement and anomalous dispersion techniques. Maximum Entropy methods are also described and discussed. Sets of test structures are used to verify, throughout the various chapters, the mathematical techniques there described and to provide practical examples of applications. This book will appeal to a wide variety of readers - offering both a comprehensive description of direct methods in crystallography and an invaluable reference tool. The first three chapters can be considered as an introduction to the field, with sufficient material to constitute a university course and for allowing the expert use of most direct methods programs. Subsequent chapters are aimed at graduate students and working crystallographers. Basic results are described and discussed in the main body of the text, while the appendices compliment these with in depth mathematical details. The quoted literature is extremely wide and the interested reader can find suggestions for future work and further reading throughout the book.Customer Reviews:
