Phase Transitions by Moshe Gitterman Pdf

This book provides a comprehensive review of the theory of phase transitions and its modern applications, based on the five pillars of the modern theory of phase transitions: the Ising model, mean field, scaling, renormalization group and universality. This expanded second edition includes, along with a description of vortices and high temperature superconductivity, a discussion of phase transitions in chemical reactions and moving systems. The book covers the close connection between phase transitions and small world phenomena as well as scale-free systems such as the stock market and the Internet.

Phase Change in Mechanics by Michel Frémond Pdf

Predictive theories of phenomena involving phase change with applications in engineering are investigated in this volume, e.g. solid-liquid phase change, volume and surface damage, and phase change involving temperature discontinuities. Many other phase change phenomena such as solid-solid phase change in shape memory alloys and vapor-liquid phase change are also explored. Modeling is based on continuum thermo-mechanics. This involves a renewed principle of virtual power introducing the power of the microscopic motions responsible for phase change. This improvement yields a new equation of motion related to microscopic motions, beyond the classical equation of motion for macroscopic motions. The new theory sensibly improves the phase change modeling. For example, when warm rain falls on frozen soil, the dangerous black ice phenomenon can be comprehensively predicted. In addition, novel equations predict the evolution of clouds, which are themselves a mixture of air, liquid water and vapor.

Phase Change Materials and Their Applications by Mohsen Mhadhbi Pdf

Today, the application of phase change materials (PCMs) has developed in different industries, including the solar cooling and solar power plants, photovoltaic electricity systems, the space industry, waste heat recovery systems, preservation of food and pharmaceutical products, and domestic hot water. PCMs use the principle of latent heat thermal storage to absorb energy in large quantities when there is a surplus and release it when there is a deficit. This promising technology has already been successfully implemented in many construction projects. The aim of this book is to assist the scientists and to provide the reader with a comprehensive overview of the properties that characterize the phase change materials from theoretical and experimental perspectives with a focus on their technological applications. The present status and future perspectives of phase change material are discussed.

Phase Change by Douglas S. Robertson Pdf

Robertson's earlier work, The New Renaissance projected the likely future impact of computers in changing our culture. Phase Change builds on and deepens his assessment of the role of the computer as a tool driving profound change by examining the role of computers in changing the face of the sciences and mathematics. He shows that paradigm shifts in understanding in science have generally been triggered by the availability of new tools, allowing the investigator a new way of seeing into questions that had not earlier been amenable to scientific probing.

Colloidal Nanoparticles for Phase Change Memory Applications by Marissa Anne Caldwell Pdf

Phase change (PC) memory has emerged as a leading candidate for next generation information storage technology. Based on the reversible amorphous-crystalline phase transition of chalcogenide materials, PC technology has already been commercialized through the optical disk industry and is currently being evaluated for non-volatile electronic data storage as phase change random access memory (PCRAM). In either the optical or electronic application, device performance relies on the material properties of the active phase change material (PCM). Traditionally deposited through physio-chemical routes such as sputtering or chemical vapor deposition, the PCM fundamentally limits PC scaling potential as it is expected that key properties will change as the volume of PCM decreases. Colloidal nanoparticle systems provide a unique opportunity to systematically study the properties of materials in the nanosize regime due to the potential for exquisite composition and size control. In this talk, I will present the first colloidal nanoparticle system of a known phase change material. Colloidal GeTe nanoparticles 1.4-4nm in diameter were synthesized through a co-precipitation route and characterized by transmission electron microscopy, energy dispersive x-ray spectroscopy and x-ray diffraction. Nuclear magnetic resonance spectroscopy (1H and 31P) was used to elucidate the molecular species involved in the reaction pathway and found that a metal center mediated proton transfer is necessary to mediate the relative reactivity of the reactants. In addition, a post-synthetic size selective procedure was developed to separate the nanoparticles into distinct size ranges. Using in-situ heating, the size dependent crystallization temperature was measured by XRD and was found to increase with decreasing nanoparticle diameter suggesting favorable improvements in lifetime data retention for scaled PCRAM cells. To evaluate the potential use in PCRAM devices, electrical measurements were also collected on nanoparticle films. Resistance versus temperature measurements revealed that nanoparticle films retained the high resistive contrast between the amorphous and crystalline phases necessary for PCRAM operation. After design optimization, PCRAM cells were fabricated utilizing the nanoparticles as a solution processable precursor to the PCM. Completed cells showed reversible switching, including threshold switching, characteristic of PCRAM operation. Cycling up to 200 times, the cells are the best performing solution processed PCRAM devices reported to date, suggesting that colloidal nanoparticles are a viable route to PCMs.

Continuum Models for Phase Transitions and Twinning in Crystals by Mario Pitteri,G. Zanzotto Pdf

Continuum Models for Phase Transitions and Twinning in Crystals presents the fundamentals of a remarkably successful approach to crystal thermomechanics. Developed over the last two decades, it is based on the mathematical theory of nonlinear thermoelasticity, in which a new viewpoint on material symmetry, motivated by molecular theories, plays a central role. This is the first organized presentation of a nonlinear elastic approach to twinning and displacive phase transition in crystalline solids. The authors develop geometry, kinematics, and energy invariance in crystals in strong connection and with the purpose of investigating the actual mechanical aspects of the phenomena, particularly in an elastostatics framework based on the minimization of a thermodynamic potential. Interesting for both mechanics and mathematical analysis, the new theory offers the possibility of investigating the formation of microstructures in materials undergoing martensitic phase transitions, such as shape-memory alloys. Although phenomena such as twinning and phase transitions were once thought to fall outside the range of elastic models, research efforts in these areas have proved quite fruitful. Relevant to a variety of disciplines, including mathematical physics, continuum mechanics, and materials science, Continuum Models for Phase Transitions and Twinning in Crystals is your opportunity to explore these current research methods and topics.

Photoinduced Phase Transitions by Keiichir? Nasu Pdf

A new class of insulating solids was recently discovered. When irradiated by a few visible photons, these solids give rise to a macroscopic excited domain that has new structural and electronic orders quite different from the starting ground state. This occurrence is called ?photoinduced phase transition?, and this multi-authored book reviews recent theoretical and experimental studies of this new phenomenon.Why and how do photoexcited few electrons finally result in an excited domain with a macroscopic size? How is the resultant photoinduced phase different from the ordinary thermal-induced phase? This review volume answers those essential questions.This book has been selected for coverage in: ?
