Modification and Blending of Synthetic and Natural Macromolecules - Proceedings of the NATO Advanced Study Institute on Modification and Blending of Synthetic and Natural Macromolecules for Preparing Multiphase Structure and Functional Materials, Pisa, Italy, 6 - 16 October 2003. (Hardcover, 2004 ed.)

R4,556 Discovery Miles 45 560 Ships in 10 - 15 working days

The book provides a unique collection of 15 contributions by 15 internationally recognized scientists performing intensive research activity on the preparation and characterization of complex and multiphase materials based on macromolecules as well as on the evaluation and simulation of structure/properties relations. The topic is assuming a general increasing importance as providing a highly sustainable and modern approach to the present and future development of the important area of materials science and technology. The scientific route along the successive contributions goes from the controlled preparation of functional MM both by innovative polymerization reactions and preformed polymers modification (intramacromolecular complexity), to their combination with other MMs and materials to give blends and composites where new properties are conveniently achieved by morphologic complexity. The synergic behaviour of the different components in these last is obtained by reactive processing producing the necessary interfacial adhesion. Even if most examples deal with man-made MMs, biopolymers are also included. The various chapters provide in most cases an exhaustive fundamental description assisted by an up- to-date and broad list of relevant references The book is therefore an excellent informative and formative instrument for those involved in complex materials preparation and application in research and industry.

Biotechnology and Polymers (Hardcover, 1991 ed.): C.G. Gebelein Biotechnology and Polymers (Hardcover, 1991 ed.)

The term biotechnology has emerged on the contemporary scene fairly recently, but the basic concept of utilizing natural materials, either directly or in modified versions, dates back to antiquity. If we search the ancient literature, such as the Bible, we find hundreds of examples wherein people employed, or modified, natural materials for a variety of important uses. As far back as the days of Noah we find pitch, a natural material, being used as a caulk. Clothing was made from animal skins and the products of several plants. Today, we would consider these things as important biotechnological developments. Likewise, the human use of polymeric materials also has a long his tory. In fact, many of the original materials used by mankind were poly mers derived from nature, such as wood, flax, cotton, wool and animal skins, which were used for shelter and clothing. In recent years, however, the concept of biotechnology has taken on a new and renewed role in our society. This is due to a combination of factors, including an increased interest in environmental concerns and the desire to break free from the stranglehold that petrochemicals have placed on our society. If we can manufacture some of our polymers from renewable resources, then we can expect to prepare them for many more years into the future than we might if we could only depend on the petro chemical resources.

Analytical Ultracentrifugation of Polymers and Nanoparticles (Hardcover, 2006 ed.): Walter Maechtle, Lars Boerger Analytical Ultracentrifugation of Polymers and Nanoparticles (Hardcover, 2006 ed.)
Walter Maechtle, Lars Boerger
R2,892 Discovery Miles 28 920 Ships in 10 - 15 working days

Analytical ultracentrifugation (AUC) is a powerful method for the characterization of polymers, biopolymers, polyelectrolytes, nanoparticles, dispersions, and other colloidal systems. The method is able to determine the molar mass, the particle size, the particle density and interaction parameters like virial coefficients and association constants. Because AUC is also a fractionation method, the determination of the molar mass distribution, the particle size distribution, and the particle density distribution is possible. A special technique, the density gradient method, allows fractionating heterogeneous samples according to their chemical nature that means being able to detect chemical heterogeneity. The book is divided into chapters concerning instrumentation, sedimentation velocity runs, density gradient runs, application examples and future developments. In particular, the detailed application chapter demonstrates the versatility and power of AUC by means of many interesting and important industrial examples. Thus the book concentrates on practical aspects rather than details of centrifugation theory.

Both authors have many years of experience in an industrial AUC research laboratory of a world leading chemical company.

Peer-reviewed contributions from internationally known specialists, describe several methods and approaches designed to create new lipid courses, modify existing courses, and serve as a basis for pursuing novel avenues of instruction. Divided into two sections, the first focuses on teaching strategies and outlines some of the barriers that lipid science specialists face when transmitting accurate information. It emphasizes the development and implementation of creative programs that foster interest in lipid science, and presents novel problem-solving approaches. It discusses strategies for involving and evaluating independent study students and explains the successful use of sample cards to teach oilseed and cereal processing. This section also provides generalized accounts of biotechnology and crop improvement and isoprenoid biochemistry, including improvement of oilseed crops and tips on explaining DNA science and crop biotechnology. The second section begins with simple demonstrations on the physical properties of lipids suitable for middle- and high school students. It follows with more complex experiments on analyzing lipids in food oils, plasma, and milk utilizing thin layer chromatography, gas chromatography, and high performance liquid chromatography. Contributions include information on convenient enzyme test kits with exercises that can translate to a lab course beginning with chromatographic methods for lipid analysis. The final chapter presents theory and experiments for studying lipid metabolism in the plastid by describing preparation methods, studying metabolite uptake, and pathway analysis.

This book presents a comprehensive study on a new class of branched polymers, known as hyperbranched polymers (HBPs). It discusses in detail the synthesis strategies for these particular classes of polymers as well as biocompatible and biodegradable HBPs, which are of increasing interest to polymer technologists due to their immense potential in biomedical applications. The book also describes the one-pot synthesis technique for HBPs, which is feasible for large-scale production, as well as HBPs' structure-property relationship, which makes them superior to their linear counterparts. The alterable functional groups present at the terminal ends of the branches make HBPs promising candidates in the biomedical domain, and the book specifically elaborates on the suitable characteristic properties of each of the potential biological HBPs' applications. As such, the book offers a valuable reference guide for all scientists and technologists who are interested in using these newly developed techniques to achieve faster and better treatments.

R2,888 Discovery Miles 28 880 Ships in 10 - 15 working days

Structure formation in crystallizing polymers, as occurring during processing, has not been treated so far in a coherent form. This fact explains, why this monograph is written as the ?rst book devoted to this subject. A quarter of a century ago the underdevelopment of this subject was obvious. Trial and error dominated. In fact, other apposite subjects as polymer melt rheology or heat transfer, had reached high levels. A great number of books has been devoted to them. Mold ?lling of amorphous polymers and the solidi?cation of these polymers by vitri?cation can nowadays be simulated numerically with a high degree of accuracy. In the solidi?ed sample even residual stresses and corresponding birefringence effects can accurately be 1 calculated . However, semicrystalline polymers, which form the majority of industrial po- mers, have been excluded from these considerations for good reasons. In fact, great uncertainties existed about the formation of quality determining crystalline str- tures. In particular, polyole?ns suffered from this shortcoming. In 1983 this fact instigated the polymer research group at the Johannes Kepler University in Linz to start with pertinent activities. The urgency of this kind of studies becomes evident, if advantages and hitches of these polymers are considered. 1. Versatility of processing: Injection molding into a great variety of shapes and sizes, from thin walled beakers to garden chairs, not to forget pipe and pro?le extrusion, cable coating, ?ber spinning, ?lm blowing. 2. Product qualities: Ductility, low density, good electric insulation, corrosion resistance, surface quality.

Silicon Based Polymers presents highlights in advanced research and technological innovations using macromolecular organosilicon compounds and systems, as presented in the 2007 ISPO congress. Silicon-containing materials and polymers are used all over the world and in a variety of industries, domestic products and high technology applications.

Among them, silicones are certainly the most wella "known, however there are still new properties discovered and preparative processes developed all the time, therefore adding to their potential. Less known, but in preparation for the future, are other silicon containing-polymers which are now close to maturity and in fact some are already available like polysilsesquioxanes and polysilanes.

All these silicon based materials can adopt very different structures like chains, dendrimers, hyperbranched and networks, physical and chemical gels. The result is a vast array of materials with applications in various areas such as optics, electronics, ionic electrolytes, liquid crystals, biomaterials, ceramics and concrete, paints and coatings a ] all needed to face the environmental, energetical and technological issues of today. Some industrial aspects of the applications of these materials will also be presented.

R5,767 Discovery Miles 57 670 Ships in 10 - 15 working days

Beads made from Egyptian faience have been excavated from grave deposits (c. 4000-3100 BC), together with beads of glazed steatite (a soft rock) and of se- precious stones such as turquoise, carnelian, quartz, and lapis lazuli. Information on these and many more ancient beads used for ornaments and jewelry, ritual ceremonies, as art artifacts and gifts for amorous women throughout history, and descriptions of the raw materials (e. g. , glass, bone, precious and other stones) and manufacturing technologies used for their production can be located in many references. Many books are devoted to the description of beads that are not of water-soluble polymer origin, techniques for their production, their art, value, and distribution, re?ecting the wealth of information existing in this ?eld of science and art. On the other hand, there are no books fully devoted to the fascinating topic of hydrocolloid (polymeric) beads and their unique applications. A few books c- tain scattered chapters and details on such topics, while emphasizing the possibility of locating fragments of information elsewhere; however, again, there is no book that is solely devoted to hydrocolloid beads and their versatile applications. In the meantime, the use of water-soluble hydrocolloid beads is on the rise in many ?elds, making a book that covers both past and novel applications of such beads, as well as their properties and ways in which to manipulate them, crucial.

Gerard Caneba
R4,387 Discovery Miles 43 870 Ships in 10 - 15 working days

The free-radical retrograde-precipitation polymerization (FRRPP) process was introduced by the author in the early 1990s as a chain polymerization method, whereby phase separation is occurring while reactive sites are above the lower cr- ical solution temperature (LCST). It was evident that certain regions of the product polymer attain temperatures above the average ?uid temperature, sometimes rea- ing carbonization temperatures. During the early stages of polymerization-induced phase separation, nanoscale polymer domains were also found to be persistent in the reacting system, in apparent contradiction with results of microstructural coarsening from constant-temperature modeling and experimental studies. This mass con?- ment behavior was used for micropatterning, for entrapment of reactive radical sites, and for the formation of block copolymers that can be used as intermediates, surf- tants, coatings, coupling agents, foams, and hydrogels. FRRPP-based materials and its mechanism have also been proposed to be relevant in energy and environmentally responsible applications. This technology lacks intellectual appeal compared to others that have been p- posed to produce polymers of exotic architectures. There are no special chemical mediators needed. Control of conditions and product distribution is done by p- cess means, based on a robust and ?exible free-radical-based chemistry. Thus, it can readily be implemented in the laboratory and in production scale.

Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic, and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles, and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist.

R8,929 Discovery Miles 89 290 Ships in 12 - 19 working days

Intrigued as much by its complex nature as by its outsider status in traditional organic chemistry, the editors of The Organic Chemistry of Sugars compile a groundbreaking resource in carbohydrate chemistry that illustrates the ease at which sugars can be manipulated in a variety of organic reactions. Each chapter contains numerous examples demonstrating the methods and strategies that apply mainstream organic chemistry to the chemical modification of sugars. The book first describes the discovery, development, and impact of carbohydrates, followed by a discussion of protecting group strategies, glycosylation techniques, and oligosaccharide syntheses. Several chapters focus on reactions that convert sugars and carbohydrates to non-carbohydrate molecules including the substitution of sugar hydroxyl groups to new groups of synthetic or biological interest, cyclitols and carbasugars, as well as endocyclic heteroatom substitutions. Subsequent chapters demonstrate the use of sugars in chiral catalysis, their roles as convenient starting materials for complex syntheses involving multiple stereogenic centers, and syntheses for monosaccharides. The final chapters focus on new and emerging technologies, including approaches to combinatorial carbohydrate chemistry, the biological importance and chemical synthesis of glycopeptides, and the medicinally significant concept of glycomimetics. Presenting the organic chemistry of sugars as a solution to many complex synthetic challenges, The Organic Chemistry of Sugars provides a comprehensive treatment of the manipulation of sugars and their importance in mainstream organic chemistry. Daniel E. Levy, editor of the Drug Discovery Series, is the founder of DEL BioPharma, a consulting service for drug discovery programs. He also maintains a blog that explores organic chemistry.

R4,568 Discovery Miles 45 680 Ships in 10 - 15 working days

To the biochemist, water is, of course, the only solvent worthy of consideration, because natural macromolecules exhibit their remarkable conformational properties only in aqueous media. Probably because of these remarkable properties, biochemists do not tend to regard proteins, nucleotides and polysaccharides as polymers in the way that real polymer scientists regard methyl methacrylate and polyethylene. The laws of polymer statistics hardly apply to native biopolymers. Between these two powerful camps, lies the No-man's land of water soluble synthetic polymers: here, we must also include natural polymers which have been chemically modified. The scientific literature of these compounds is characterized by a large number of patents, which is usually a sign of little basic understanding, of 'know-how' rather than of 'know-why'. Many of the physical properties of such aqueous solutions are intriguing: the polymer may be completely miscible with water, and yet water is a 'poor' solvent, in terms of polymer parlance. ~kiny of the polymers form thermorever sible gels on heating or cooling. The phenomena of exothermic mixing and salting-in are common features of such systems: neither can be fully explained by the available theories. Finally, the eccentric behaviour of polyelectrolytes is well documented. Despite the lack of a sound physico-chemical foundation there is a general awareness of the importance of water soluble vinyl, acrylic, polyether, starch and cellulose derivatives, as witnessed again by ~he vast patent literature.

In an ever-increasing domain of activity Amino Acids Peptides and Proteins provides an annual compilation of the world's research effort into this important area of biological chemistry. Volume 30 provides a review of literature published during 1997. Comprising a comprehensive review of significant developments at this biology/chemistry interface each volume opens with an overview of amino acids and their applications. Work on peptides is reviewed over several chapters ranging from current trends in their synthesis and conformational and structural analysis to peptidomimetics and the discovery of peptide-related molecules in nature. The application of advanced techniques in structural elucidation is incorporated into all chapters whilst periodic chapters on metal complexes of amino acids, peptides and beta-lactams extend the scope of coverage. Efficient searching of specialist topics is facilitated by the sub-division of chapters into discrete subject areas allowing annual trends to be monitored. All researchers in the pharmaceutical and allied industries and at the biology/chemistry interface in academia will find this an indispensable reference source.

Although size exclusion chromatography (SEC) is perhaps the most popular and widely used technique for determining the molecular weight distribution of polymeric materials, there have been very few texts written on this topic. During the past decade, SEC has experienced a considerable amount of growth in regard to column and detector technology and new applications. With these advances, SEC can now be used for determining absolute molecular weight, polymer chain conformation and size, and branching, as well as polymer solution properties. This book introduces the reader to the fundamentals of SEC with emphasis on practical aspects of the technique, such as column and mobile selection, calibration, new detector capabilities and guidelines for performing SEC on most types of polymers, especially those of industrial importance. This book is intended for either those new to the field of SEC, or for those research workers who require a more comprehensive background.

This book is a snapshot of the current state of the art of research and development on the properties and characteristics of silk and their use in medicine and industry. The field encompasses backyard silk production from ancient time to industrial methods in the modern era and includes an example of efforts to maintain silk production on Madagascar. Once revered as worth its weight in gold, silk has captured the imagination from its mythical origins onwards. The latest methods in molecular biology have opened new descriptions of the underlying properties of silk. Advances in technological innovation have created silk production by microbes as the latest breakthrough in the saga of silk research and development. The application of silk to biomaterials is now very active on the basis of excellent properties of silks including recombinant silks for biomaterials and the accumulated structural information.
