Download or read book Reconstructive Phase Transitions In Crystals And Quasicrystals written by Vladimir Dmitriev and published by World Scientific. This book was released on 1996-09-30 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the phenomenological theory of first-order structural phase transitions, with a special emphasis on reconstructive transformations in which a group-subgroup relationship between the symmetries of the phases is absent. It starts with a unified presentation of the current approach to first-order phase transitions, using the more recent results of the Landau theory of phase transitions and of the theory of singularities. A general theory of reconstructive phase transitions is then formulated, in which the structures surrounding a transition are expressed in terms of density-waves, providing a natural definition of the transition order-parameters, and a description of the corresponding phase diagrams and relevant physical properties. The applicability of the theory is illustrated by a large number of concrete examples pertaining to the various classes of reconstructive transitions: allotropic transformations of the elements, displacive and order-disorder transformations in metals, alloys and related structures, crystal-quasicrystal transformations.

Download or read book Structural Phase Transitions II written by K. Alex Müller and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural Phase Transitions II, like its predecessor (Topics in Current Physics, Vol. 23), presents selected methods and recent advances in the experimental investigation of phase transitions in solids. The two chapters in this volume deal with electron paramagnetic resonance (EPR), and with nuclear magnetic and nuclear quadrupole resonance (NMR-NQR). Both techniques are particularly sensitive to local properties. The chapter on EPR concentrates largely on the investigation of static properties, including mean-field behaviour, critical and multicritical phenomena, whilst NMR is shown to be a powerful tool for studying nonlinear dynamics, incommensurate transitions, and disordered systems. This book will serve as an excellent introduction to the methodology and applications of EPR and NMR-NQR for all those wishing to become acquainted with these important tools for studying structural phase transitions.

Download or read book Biochemical and Clinical Aspects of Hemoglobin Abnormalities written by Winslow Caughey and published by Elsevier. This book was released on 2012-12-02 with total page 746 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochemical and Clinical Aspects of Hemoglobin Abnormalities contains the proceedings of a symposium held on the Pingree Park campus of Colorado State University on October 2-7, 1977. Contributors discuss the biochemical and clinical aspects of hemoglobin abnormalities and cover topics ranging from amino acid substitutions to sickle cell disease, glycosylated hemoglobins, cystamine inhibition of sickling, and gelation of sickle cell hemoglobin. This volume is organized into 52 chapters and begins with a discussion of the role of distal residues in structure, ligand binding, and oxidation of hemoglobins A, Zurich, and Sydney. It then turns to functional abnormalities of whole blood in sickle cell anemia, inhibition of sickle hemoglobin gelation by amino acids and peptides, and intermolecular interactions in crystals of human deoxy hemoglobins A, C, F, and S. The chapters that follow focus on glycosylation of human hemoglobin, the phase transitions of sickle-cell hemoglobin, conformational effects of the HbS mutation, and mechanisms for hemoglobin oxidation. The reader is also introduced to oxidation of oxyhemoglobin by reductants, the kinetics of oxygen binding to human red blood cells, and oxidation of human hemoglobin by copper. A chapter that assesses the effect of physiological parameters, such as pH, oxygen concentration, protein concentration, non-gelling hemoglobins, and the erythrocyte membrane, on the kinetics of polymerization of deoxyhemoglobin S concludes the book. This book is intended for biochemists and clinicians interested in knowing more about hemoglobin abnormalities.

Download or read book Science and Technology of Crystal Growth written by J.P. van der Eerden and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. The ninth International Summer School on Crystal Growth. ISSCG IX A complete theory of crystal growth establishes the full dependence of crystal size, shape and structure on external parameters like temperature, pressure, composition, purity, growth rate and stirring of the mother phase, implicitly establishing how the corresponding fields vary in space and time. Such a theory does not exist, however. Therefore equipment to grow crystals is developed on the basis of partial knowledge. Skill, experience and creativity still are of central importance for the success o~ a crystal growth system. In this book we collected contributions from the teachers of the ninth International Summer School on Crystal Growth ISSCG IX, held 11-16 june 1995 at Papendal, the national sports centre of the Netherlands. These contributions were used during the lectures. The authors have tried to present their work in such a way that only basic physical knowledge is required to understand the papers. The book can be used as an introduction to various important sub disciplines of the science and technology of crystal growth. Since, however the information content considerably exceeds a lecture note level and touches the present limits of understanding, it is an up to date handbook as well.

Download or read book Modern Charge Density Analysis written by Carlo Gatti and published by Springer Science & Business Media. This book was released on 2012-01-09 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Charge-Density Analysis focuses on state-of-the-art methods and applications of electron-density analysis. It is a field traditionally associated with understanding chemical bonding and the electrostatic properties of matter. Recently, it has also been related to predictions of properties and responses of materials (having an organic, inorganic or hybrid nature as in modern materials and bio-science, and used for functional devices or biomaterials). Modern Charge-Density Analysis is inherently multidisciplinary and written for chemists, physicists, crystallographers, material scientists, and biochemists alike. It serves as a useful tool for scientists already working in the field by providing them with a unified view of the multifaceted charge-density world. Additionally, this volume facilitates the understanding of scientists and PhD students planning to enter the field by acquainting them with the most significant and promising developments in this arena.

Download or read book Photons In Fock Space And Beyond In 3 Volumes written by Reinhard Honegger and published by World Scientific. This book was released on 2015-04-22 with total page 2353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume major reference “Photons in Fock Space and Beyond” undertakes a new mathematical and conceptual foundation of the theory of light emphasizing mesoscopic radiation systems. The quantum optical notions are generalized beyond Fock representations where the richness of an infinite dimensional quantum field system, with its mathematical difficulties and theoretical possibilities, is fully taken into account. It aims at a microscopic formulation of a mesoscopic model class which covers in principle all stages of the generation and propagation of light within a unified and well-defined conceptual frame.The dynamics of the interacting systems is founded — according to original works of the authors — on convergent perturbation series and describes the developments of the quantized microscopic as well as the classical collective degrees of freedom at the same time. The achieved theoretical unification fits especially to laser and microwave applications inheriting objective information over quantum noise.A special advancement is the incorporation of arbitrary multiply connected cavities where ideal conductor boundary conditions are imposed. From there arises a new category of classical and quantized field parts, apparently not treated in Quantum Electrodynamics before. In combination with gauge theory, the additional “cohomological fields” explain topological quantum effects in superconductivity. Further applications are to be expected for optoelectronic and optomechanical systems.

Download or read book Symmetry Relationships between Crystal Structures written by Ulrich Müller and published by OUP Oxford. This book was released on 2013-04-04 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: In crystal chemistry and crystal physics, the relations between the symmetry groups (space groups) of crystalline solids are of special importance. Part 1 of this book presents the necessary mathematical foundations and tools: the fundamentals of crystallography with special emphasis on symmetry, the theory of the crystallographic groups, and the formalisms of the needed crystallographic computations. Part 2 gives an insight into applications to problems in crystal chemistry. With the aid of numerous examples, it is shown how crystallographic group theory can be used to make evident relationships between crystal structures, to set up a systematic order in the huge amount of known crystal structures, to predict crystal structures, to analyse phase transitions and topotactic reactions in the solid state, to understand the formation of domains and twins in crystals, and to avoid errors in crystal structure determinations. A broad range of end-of-chapter exercises offers the possibility to apply the learned material. Worked-out solutions to the exercises can be found at the end of the book.

Download or read book Science Is Not A Quiet Life Unravelling The Atomic Mechanism Of Haemoglobin written by Max F Perutz and published by World Scientific. This book was released on 1998-01-15 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linus Pauling called haemoglobin the most interesting and important of molecules. This important volume shows how X-ray crystallography was used to determine its bewilderingly complex atomic structure and to unravel the stereochemical mechanisms of its respiratory functions. It introduces isomorphous replacement with heavy atoms which led to the first protein structures, haemoglobin and its simpler relative myoglobin. Later papers deal with the stereochemistry of the cooperative effects of haemoglobin, with the relationships between the structures and impaired functions of abnormal haemoglobin, with species adaptation of haemoglobin, and with its action as a drug receptor and as an oxygen sensor. The final papers deal with amino acid repeats which act as polar zippers and their role in certain inherited neurodegenerative diseases.

Download or read book Reviews Of Accelerator Science And Technology Volume 10 The Future Of Accelerators written by Weiren Chou and published by World Scientific. This book was released on 2019-09-09 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 10 in the series of the annual journal Reviews of Accelerator Science and Technology (RAST), will be its final volume. Its theme is 'The Future of Accelerators'. This volume, together with previous 9 volumes, gives readers a complete picture as well as detailed technical information about the accelerator field, and its many driving and fascinating aspects.This volume has 17 articles. The first 15 articles have a different approach from the previous volumes. They emphasize the more personal views, perspectives and advice from the frontier researchers rather than provide a review or survey of a specific subfield. This emphasis is more aligned with the theme of the current volume. The other two articles are dedicated respectively to Leon Lederman and Burton Richter, two prominent leaders of our community who left us last year.
