This book provides a comprehensive account of the reactions between
clay minerals and organic polymers. The book opens with a
discussion of the structures of common clay minerals, clays colloid
chemistry, and the behaviour of organic polymers at clay surfaces.
This is followed by a systematic treatment of complex formation
between clay minerals and various classes of synthetic and
naturally occurring polymers, a description of the properties of
the resulting complexes and, wherever appropriate, their practical
applications. The book will have a new separate chapter on
clay-polymer nanocomposites. Each chapter is written as a
self-contained review paper, giving a list of reference to the
original literature.

This book presents an introduction to viscoelasticity, in particular, to the theories of dilute polymer solutions and dilute suspensions of rigid particles in viscous and incompressible fluids. These theories are important, not just because they apply to practical problems of industrial interest, but because they form a solid theoretical base upon which mathematical techniques can be built, from which more complex theories can be constructed, to better mimic material behaviour. The emphasis of this book is not on the voluminous current topical research, but on the necessary tools to understand viscoelasticity. This is a compact book for a first year graduate course in viscoelasticity and modelling of viscoelastic multiphase fluids. The Dissipative Particle Dynamics (DPD) is introduced as a particle-based method, relevant in modelling of complex-structured fluids. All the basic ideas in DPD are reviewed. The third edition has been updated and expanded with new results in the meso-scale modelling, links between the fluid modelling to its physical parameters and new matlab programs illustrating the modelling. Particle-based modelling techniques for complex-structure fluids are added together with some sample programs. A solution manual to the problems is included.
Successful characterization of polymer systems is one of the most
important objectives of today's experimental research of polymers.
Considering the tremendous scientific, technological, and economic
importance of polymeric materials, not only for today's
applications but for the industry of the 21st century, it is
impossible to overestimate the usefulness of experimental
techniques in this field. Since the chemical, pharmaceutical,
medical, and agricultural industries, as well as many others,
depend on this progress to an enormous degree, it is critical to be
as efficient, precise, and cost-effective in our empirical
understanding of the performance of polymer systems as possible.
This presupposes our proficiency with, and understanding of, the
most widely used experimental methods and techniques. * Addresses the most important practical techniques for
experimental research in the growing field of polymer science

This book comprehensively summarizes important aspects of research in the active field of lignocellulosic (polymer) composites, including polymer materials from or containing cellulose, hemicellulose and lignin. It describes how these materials can be produced from forest products and natural fibers from sources such as jute, flax, sisal, and many more, and even from agricultural residues (like wheat straw, corn stover, or sugarcane bagasse). In times of high demand for renewable green materials, lignocellulosic materials from organic matter produced by trees, shrubs and agricultural crops present a highly attractive feedstock. The international authors explain different treatment and fabrication methods for the production of lignocellulosic materials. Other chapters address the properties of these green materials or illustrate specific applications, ranging from food packaging and household products to adsorbents and even conductive polymer composites. In this way, this book offers a broad and comprehensive overview over the entire field of lignocellulosic composite materials.

Volume 11 of this series presents five timely reviews on current
research on alkaloids. Chapter 1 by Paul L. Schiff, Jr. is a
monumental survey of research that has been carried out over the
past decade on the "Thalictrum" alkaloids. Forty-six new alkaloids
are described from fifteen species of the genus "Thalictrum," as
well as 116 alkaloids of known structure from thirty-six species
and subspecies of the genus. The chapter includes discussions of
isolation and structure elucidation, analysis, biosynthesis, cell
culture, and pharmacology. Also featured are inclusive compilations
of botanical sources, alkaloids by alkaloid types, and calculated
molecular weights of the "Thalictrum" alkaloids. Chapter 2 by Giovanni Appendino provides a fascinating treatment
of Taxine, a collective name referring to a mixture of diterpenoid
alkaloids from the yew tree (genus: "Taxus"). Taxine is responsible
for the toxic properties of the yew tree that has been documented
in historical and fictional literature, from Julius Caesar to
Shakespeare, and from Agatha Christie to T.S. Eliot. The chapter
treats the history, isolation techniques, structure elucidation,
chemistry, and pharmacology of Taxine. Chapter 3 by Mary D. Menachery surveys the alkaloids of South
American Menispermaceae (moonseed family). Many different
structural types are included in this family. The alkaloid-bearing
plants are woody-vines, shrubs, or small trees. Several of these
species possess potent curare activity. The chemistry as well as
pharmacology of these alkaloids is summarized. Chapter 4 by Russell J. Molyneux, Robert J. Nash, and Naoki
Asano treats the chemistry and biological activity of the
calystegines and related "nor"tropane alkaloids. These
polyhydroxylated bicyclic alkaloids represent another class of
compounds that inhibit glycosidases, producing profound effects in
biological systems by disrupting the essential cellular function of
glycoprotein processing. Chapter 5, a related chapter by Robert J. Nash, Naoki Asano, and Alison A. Watson, reviews polyhydroxylated alkaloids that inhibit glycosidases. Topics covered include distribution, ecological significance and toxicity, isolation, synthesis, and biosynthesis.
This book focuses on the microscopic understanding of the function of organic semiconductors. By tracing the link between their morphological structure and electronic properties across multiple scales, it represents an important advance in this direction. Organic semiconductors are materials at the interface between hard and soft matter: they combine structural variability, processibility and mechanical flexibility with the ability to efficiently transport charge and energy. This unique set of properties makes them a promising class of materials for electronic devices, including organic solar cells and light-emitting diodes. Understanding their function at the microscopic scale - the goal of this work - is a prerequisite for the rational design and optimization of the underlying materials. Based on new multiscale simulation protocols, the book studies the complex interplay between molecular architecture, supramolecular organization and electronic structure in order to reveal why some materials perform well - and why others do not. In particular, by examining the long-range effects that interrelate microscopic states and mesoscopic structure in these materials, the book provides qualitative and quantitative insights into e.g. the charge-generation process, which also serve as a basis for new optimization strategies.
This book addresses a range of synthesis and characterization techniques that are critical for tailoring and broadening the various aspects of polymer gels, as well as the numerous advantages that polymer gel-based materials offer.
