Fast Scanning Calorimetry


Book Description

In the past decades, the scan rate range of calorimeters has been extended tremendously at the high end, from approximately 10 up to 10 000 000 °C/s and more. The combination of various calorimeters and the newly-developed Fast Scanning Calorimeters (FSC) now span 11 orders of magnitude, by which many processes can be mimicked according to the time scale(s) of chemical and physical transitions occurring during cooling, heating and isothermal stays in case heat is exchanged. This not only opens new areas of research on polymers, metals, pharmaceuticals and all kinds of substances with respect to glass transition, crystallization and melting phenomena, it also enables in-depth study of metastability and reorganization of samples on an 1 to 1000 ng scale. In addition, FSC will become a crucial tool for understanding and optimization of processing methods at high speeds like injection molding. The book resembles the state-of-the art in Thermal Analysis & Calorimetry and is an excellent starting point for both experts and newcomers in the field.

Handbook of Conducting Polymers, Fourth Edition - 2 Volume Set


Book Description

In the last 10 years there have been major advances in fundamental understanding and applications and a vast portfolio of new polymer structures with unique and tailored properties was developed. Work moved from a chemical repeat unit structure to one more based on structural control, new polymerization methodologies, properties, processing, and applications. The 4th Edition takes this into account and will be completely rewritten and reorganized, focusing on spin coating, spray coating, blade/slot die coating, layer-by-layer assembly, and fiber spinning methods; property characterizations of redox, interfacial, electrical, and optical phenomena; and commercial applications.




Polymers as Biomaterials


Book Description

Nearly 4000 years ago, the Egyptians used linen, a natural polymeric material, for suturing wounds. About 600 B.C., the Indians used other forms of natural polymers such as cotton, horse hair, and leather in repairing wounds. Wound closure procedures using silk sutures, based mostly on polypeptides, are likely to have been practiced during the second century. Surgical application of natural polymers continued to represent the major use of polymers until the twentieth century. Not too long after the development of several major synthetic polymers, their use in biomedical applications has attracted the attention of many re searchers and clinicians. Over the past few years, interest in the biomedical applications of polymers has grown considerably. This has been the result of the inevitable collaborative efforts of in novative materials scientists, engineers and clinicians. The es tablishment of the Society for Biomaterials, in our opinion, cata lyzed the growing interest in the use of polymers for biomedical application. In a major effort to bring team players even closer, a five-day symposium on "Polymers as Biomaterials" was held in Seattle, Washing ton, in March, 1983 as part of the national meeting of the American Chemical Society. The symposium was designed to provide a forum for communicating technical and clinical data to colleagues with a broad spectrum of interest in the biomedical applications of polymers.




Crystallography and Crystal Defects


Book Description

Extensively revised and updated, this new edition of a classic text presents a unified approach to crystallography and to the defects found within crystals. The book combines the classical and exact description of symmetry of a perfect crystal with the possible geometries of the major defects-dislocations, stacking faults, point defects, twins, interfaces and the effects of martensitic transformations. A number of important concepts and exciting new topics have been introduced in this second edition, including piezoelectricity, liquid crystals, nanocrystalline concepts, incommensurate materials and the structure of foamed and amorphous solids. The coverage of quasicrystalline materials has been extended, and the data tables, appendices and references have been fully updated. Reinforcing its unrivalled position as the core text for teaching crystallography and crystal defects, each chapter includes problem sets with brief numerical solutions at the end of the book. Detailed worked solutions, supplementary lecture material and computer programs for crystallographic calculations are provided online (http://booksupport.wiley.com).




Macromolecules


Book Description

Like so many of its kind, this textbook originated from the requirements of teaching. While lecturing on macromolecular science as a required subject for chemists and materials scientists on the undergraduate, graduate, and postgraduate levels at Swiss Federal Institute of Technology at Zurich (1960-1971), I needed a one-volume textbook which treated the whole field of macromolecular science, from its chemistry and physics to its applications, in a not too elementary manner. This textbook thus intends to bridge the gap between the often oversimplified introductory books and the highly specialized texts and monographs that cover only parts of macromolecular science. This first English edition is based on the third German edition (1975), which is about 40% different from the first German edition (1971), a result of rapid progress in macromolecular science and the less rapid education of the writer. This text intends to survey the whole field of macromolecular science. Its organization results from the following considerations. The chemical structure of macromolecular compounds should be independent of the method of synthesis, at least in the ideal case. Part I is thus concerned with the chemical and physical structure of macro molecules. Properties depend on structure. Solution properties are thus discussed in Part II, solid state properties in Part III. There are other reasons for discussing properties before syntheses: For example, it is difficult to under stand equilibrium polymerization without knowledge of solution thermody of the glass temperature, etc.




Polymer Chemistry


Book Description

A well-rounded and articulate examination of polymer properties at the molecular level, Polymer Chemistry focuses on fundamental principles based on underlying chemical structures, polymer synthesis, characterization, and properties. It emphasizes the logical progression of concepts and provide mathematical tools as needed as well as fully derived problems for advanced calculations. The much-anticipated Third Edition expands and reorganizes material to better develop polymer chemistry concepts and update the remaining chapters. New examples and problems are also featured throughout. This revised edition: Integrates concepts from physics, biology, materials science, chemical engineering, and statistics as needed. Contains mathematical tools and step-by-step derivations for example problems Incorporates new theories and experiments using the latest tools and instrumentation and topics that appear prominently in current polymer science journals. The number of homework problems has been greatly increased, to over 350 in all. The worked examples and figures have been augmented. More examples of relevant synthetic chemistry have been introduced into Chapter 2 ("Step-Growth Polymers"). More details about atom-transfer radical polymerization and reversible addition/fragmentation chain-transfer polymerization have been added to Chapter 4 ("Controlled Polymerization"). Chapter 7 (renamed "Thermodynamics of Polymer Mixtures") now features a separate section on thermodynamics of polymer blends. Chapter 8 (still called "Light Scattering by Polymer Solutions") has been supplemented with an extensive introduction to small-angle neutron scattering. Polymer Chemistry, Third Edition offers a logical presentation of topics that can be scaled to meet the needs of introductory as well as more advanced courses in chemistry, materials science, polymer science, and chemical engineering.




Thermal Analysis


Book Description

Thermal Analysis deals with the theories of thermal analysis (thermodynamics, irreversible thermodynamics, and kinetics) as well as instrumentation and techniques (thermometry, differential thermal analysis, calorimetry, thermomechanical analysis and dilatometry, and thermogravimetry). Applications of thermal analysis are also described. This book consists of seven chapters and begins with a brief outline of the history and meaning of heat and temperature before listing the techniques of thermal analysis. The reader is then introduced to the basis of thermal analysis, paying particular attention to the macroscopic theories of matter, namely, equilibrium thermodynamics, irreversible thermodynamics, and kinetics. The next chapter discusses thermometry, focusing on the international temperature scale and the techniques of measuring temperature. Examples of heating and cooling curves are linked to the discussion of transitions. The groundwork for a detailed understanding of transition temperature is given. The chapters that follow explore the principles of differential thermal analysis, calorimetry, thermomechanical analysis and dilatometry, and thermogravimetry. This book is intended for the senior undergraduate or beginning graduate student, as well as for the researcher and teacher interested in thermal analysis.
