Nmr Methods For Characterization Of Synthetic And Natural Polymers

Download or read book NMR Methods for Characterization of Synthetic and Natural Polymers written by Rongchun Zhang and published by Royal Society of Chemistry. This book was released on 2019-07-29 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of FT-NMR spectroscopy around five decades ago, NMR has achieved significant advances in hardware and methodologies, accompanied with the enhancement of spectral resolution and signal sensitivity. Rapid developments in the polymers field mean that accurate and quantitative characterization of polymer structures and dynamics is the keystone for precisely regulating and controlling the physical and chemical properties of the polymer. This book specifically focuses on NMR investigation of complex polymers for the polymer community as well as NMR spectroscopists, and will push the development of both fields. It covers the latest advances, for example high field DNP and ultrafast MAS methodologies, and show how these novel NMR methods characterize various synthetic and natural polymers.

Download or read book Liquid Chromatography of Synthetic Polymers written by Muhammad Imran Malik and published by Springer Nature. This book was released on 2023-11-03 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book elucidates the peculiar phenomenon of entropy/enthalpy compensation that takes place in high performance liquid chromatography (HPLC) of polymers. Numerous publications, including some books, are devoted to molecular characterization of synthetic polymers, materials presently produced in large and steadily growing quantities, applying methods of HPLC. A knowledge of the molecular characteristics of polymers is indispensable, not only for their proper applications but also for their recycling and remediation. Polymer scientists generally focus on synthesis and potential applications of polymers while not giving due attention to an important central link, their comprehensive characterization in context of development of structure-property correlations. To fill this gap is one of the aims of the present book. The process of entropy/enthalpy compensation plays a decisive role in the advanced method of polymer characterization such as liquid chromatography at critical conditions, eluent gradient interaction chromatography, and temperature gradient interaction chromatography. All chemists working on any aspect of polymer science will find this book a valuable resource for the development of structure-property correlations.

Download or read book Advanced Diffusion Encoding Methods in MRI written by Daniel Topgaard and published by Royal Society of Chemistry. This book was released on 2020-08-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: The medical MRI community is by far the largest user of diffusion NMR techniques and this book captures the current surge of methods and provides a primary source to aid adoption in this field. There is a trend to adapting the more advanced diffusion encoding sequences developed by NMR researchers within the fields of porous media, chemical engineering, and colloid science to medical research. Recently published papers indicate great potential for improved diagnosis of the numerous pathological conditions associated with changes of tissue microstructure that are invisible to conventional diffusion MRI. This book disseminates these recent developments to the wider community of MRI researchers and clinicians. The chapters cover the theoretical basis, hardware and pulse sequences, data analysis and validation, and recent applications aimed at promoting further growth in the field. This is a fast moving field and chapters are written by key MRI scientists that have contributed to the successful translation of the advanced diffusion NMR methods to the context of medical MRI, from global locations.

Download or read book Physical Principles of Chirality in NMR written by Piotr Garbacz and published by Royal Society of Chemistry. This book was released on 2024-09-20 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can we study one of the most elusive molecular properties, chirality, using nuclear interactions with the magnetic field that are apparently insensitive to handedness? This book answers this question from the physicochemical point of view by providing a clear, coherent, and comprehensive review of methods used in NMR studies of chirality. Presented arguments based on fundamental physical and chemical laws and in-depth descriptions of new methods utilizing purely physical interactions are mainly addressed to spectroscopists in both academia and industry. The introductory chapters provide the reader with the basics of NMR spectroscopy as a tool for the study of chiral compounds, and those more interested in the methods of chiral discrimination will benefit from the brief description of their common points and reasons why some of them may or may not work. In the following chapters, the book shows rapid progress in a newly emerging field of chirality-sensitive NMR, in particular, a search for effects that give direct information about the absolute configuration of a molecule.
