Written by a chemical physicist specializing in macromolecular physics, this book brings to life the definitive work of celebrated scientists who combined multidisciplinary perspectives to pioneer the field of polymer science. The author relates firsthand the unique environment that fostered the experimental breakthroughs underlying some of today's most widely accepted theories, mathematical principles, and models for characterizing macromolecules. Physical Chemistry of Macromolecules employs the unifying principles of physical chemistry to define the behavior, structure, and intermolecular properties of macromolecules in both solution and bulk states. The text explains the experimental techniques, such as light scattering, and results used to support current theories. Examining both equilibrium and transport properties, the book describes the properties of dilute, semi-dilute, and concentrated polymer solutions, including compressible fluids. It then covers amorphous liquids and glasses, and polymer networks. The final chapters discuss the properties of solutions containing stiff-chain molecules and polyelectrolytes. Topics also include the macromolecular nature of rubber elasticity, viscoelasticity, and the distribution of relaxation times associated with the glass transition. By explaining the experimental and mathematical basis for the theories and models used to define macromolecular behavior, Physical Chemistry of Macromolecules demonstrates how these techniques and models can be applied to analyze and predict the properties of new polymeric materials.
This book discusses various aspects of different bulk TSO single crystals in terms of thermodynamics; bulk crystal growth using diverse techniques involving gas phase, solution, and melt; and the resulting crystal size, appearance, and structural quality as well as the fundamental properties that were gathered from bulk single crystals. It presents experimental results accompanied by theoretical results, such as band structure and native defects. Combinations of various bulk single crystals along with their properties show great promise in practical device functionality and fabrication. Many TSO-based devices have already been demonstrated in several technical areas, including electronics, optoelectronics, and photovoltaics as well as sensing devices. The book is the first of its kind that brings together a variety of bulk single crystals of scientifically and technically important TSOs along with their properties, which may result in novel devices with unique functionalities.

The CRC Handbook of Enthalpy Data of Polymer-Solvent Systems presents data that is as essential to the production, process design, and use of polymers as it is to understanding the physical behavior and intermolecular interactions in polymer solutions and in developing thermodynamic polymer models. Providing an all-encompassing collection of current enthalpy data for all types of polymer solutions, this handbook is a ready companion with Christian Wohlfarth's previously published handbooks of thermodynamic data for copolymer solutions, aqueous polymer solutions, and polymer solutions at elevated pressures, which contain only a small amount of enthalpic data in comparison to the data presented here. This volume contains 1770 data sets that include enthalpies of mixing and dilution for the entire concentration range as well as partial enthalpies of mixing and solution at infinite dilution. Special appendices allow scientists to access specific systems and data easily. The CRC Handbook of Enthalpy Data of Polymer-Solvent Systems is a practical, one-stop resource that allows polymer chemists, biochemists, chemical engineers, materials scientists, and physical chemists involved in both industrial and laboratory processes to quickly retrieve relevant information as needed.
The phase behaviour of materials and their thermodynamic properties are a central subject in all fields of materials research. The first Volume of the work, meant for graduate students in chemistry, geology, physics, and metallurgy, and their engineering counterparts, is split up in three levels, such that from level to level the portion and importance of thermodynamics and mathematics are increased. In the ground level it is shown that the basic principles of phase equilibria can be understood without the use of thermodynamics - be it that the concept of chemical potential is introduced right from the beginning. The intermediate level is an introduction to thermodynamics; culminating in the Gibbs energy as the arbiter for equilibrium - demonstrated for systems where the phases in equilibrium are pure substances. In the third level the accent is on binary systems, where one or more phases are solutions of the components...
