Available in PDF, EPUB and Kindle. Book excerpt: "This work consists of two topics. The first part deals with deuterium nuclear magnetic resonance (2H NMR) study of bulk and adsorbed polymers. Segmental dynamics of poly(methyl acrylate) is examined in bulk and when adsorbed to anopore, alumina and silica as a function of temperature. The second part investigates diffusion of small molecules in polymer solutions by pulsed field-gradient proton nuclear magnetic resonance (PGSE 1H NMR). The diffusion of solvents in polymer solutions is investigated. The diffusion of N-N, dimethylformamide in polystyrene is studied as a function of concentration and temperature. The diffusion coefficients of solvents in binary solvent mixtures of methylene chloride/toluene and chloroform/acetonitrile in poly(methyl methacrylate) solutions as functions of concentration are also reported"--Introduction, leaf 1.

Book excerpt: "Cover-to-cover reading of Plastics Additives, Advanced Industrial Analysis, is recommended for both professional analysts and plastics technologists. Professor Bart’s prose style is easy to read. A professional background in analytical chemistry is not assumed. Particularly valuable is the trove of good advice as to which approach might be best in a given situation. Every department with a serious interest in additive / property relations should invest in a copy.” -- PMAD Newsletter. This industrially relevant and up-to-date resource deals with all established and emerging analytical methods for in-polymer additive analysis of plastics formulations. Quality assurance and industrial troubleshooting all benefit from direct analysis modes. Plastics Additives comprises detailed coverage of solid-state spectroscopy, thermal analysis and pyrolysis, laser techniques, surface studies and microanalysis along with process analytics, quantitative analysis and modern method development and validation applied to additives in polymers. The book is organised for quick and easy reference and is extensively illustrated with over 200 figures, 300 flow diagrams and tables to facilitate rapid understanding of this topic, and it contains 4000 references. Emphasis is on understanding (principles and characteristics) and industrial applicability.

This book was released on 2012-12-06 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global attention in scientific, industrial, and governmental communities to traces of toxic chemicals in foodstuffs and in both abiotic and biotic environ ments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to pro vide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental con tamination and toxicology. Until now there has been no journal or other publica tion series reserved exclusively for the diversified literature on "toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wildlife, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authoritative publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancil lary legislation.

Download or read book Self diffusion Studies in Polymer solvent Systems by Pulsed gradient Spin echo Nuclear Magnetic Resonance written by Roy Allen Waggoner and published by . This book was released on 1993 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Pulsed gradient NMR techniques have been used to study self-diffusion in polymer solutions. The systems studied include toluene, cyclohexane, ethylbenzene, chloroform, t-butyl acetate, and methyl ethyl ketone in polystyrene; methyl methacrylate in poly(methyl methacrylate); poly(ethylene oxide) in water; and water in biological tissue. The polymer diffusion data are evaluated in terms of scaling theory as they relate to the scaling of the polymer diffusion coefficient with molecular weight. The solvent diffusion data are evaluated with kinetic and free-volume theories. In addition a relatively simple dependence of diffusion coefficient on polymer volume fraction is derived from free-volume theory. The solvent diffusion data are employed in a model which simulated the drying of a coating by solvent evaporation. Solvent volatility is determined from solvent activity at the surface. Diffusion within the film is handled by the solution of Fick's second Law by the Crank-Nickolson implicit method. Without using any adjustable parameters the model can do an excellent job of predicting the drying curves for a good solvent-polymer two component system. The model is less successful with poorer solvents"--Abstract, leaf iii.

Download or read book Diffusion NMR of Confined Systems written by Rustem Valiullin and published by Royal Society of Chemistry. This book was released on 2016-12-13 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing role of porous solids in conventional and newly emerging technologies, there is an urgent need for a deeper understanding of fluid behaviour confined to pore spaces of these materials especially with regard to their transport properties. From its early years, NMR has been recognized as a powerful experimental technique enabling direct access to this information. In the last two decades, the methodological development of different NMR techniques to assess dynamic properties of adsorbed ensembles has been progressed. This book will report on these recent advances and look at new broader applications in engineering and medicine. Having both academic and industrial relevance, this unique reference will be for specialists working in the research areas and for advanced graduate and postgraduate studies who want information on the versatility of diffusion NMR.
