Book Synopsis Multidimensional NMR Studies of Poly(ethylene-co-1-octene) Copolymers and Poly(ethylene-co-vinyl Acetate-co-carbon Monoxide) Terpolymers by : Anuttra Nuamthanom
Download or read book Multidimensional NMR Studies of Poly(ethylene-co-1-octene) Copolymers and Poly(ethylene-co-vinyl Acetate-co-carbon Monoxide) Terpolymers written by Anuttra Nuamthanom and published by . This book was released on 2007 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The comonomer and stereo-sequences of poly(ethylene-co-1-octene) samples with varying 1-octene content and degree of tacticity were investigated using high-temperature (120 °C) one- and two- dimensional (1D and 2D) nuclear magnetic resonance (NMR) techniques on a 750 MHz instrument. The techniques used include quantitative 13C NMR, pulsed-field-gradient (PFG) 1H -13C heteronuclear single quantum coherence (gHSQC), heteronuclear multiple bond correlation (gHMBC) and heteronuclear single quantum coherence-total correlation spectroscopy (gHSQC-TOCSY). Diffusion-ordered 2D NMR spectroscopy (DOSY) was used to confirm that the copolymer samples were not mixtures of two copolymers with different MW. Quantitative analysis of octene content was determined from quantitative 13C NMR experiments. The degree of tacticity was established by quantitative volume integration of 2D gHSQC NMR spectra. The comonomer sequence distributions and the resonance assignments of poly(ethylene-co-vinyl acetate-co-carbon monoxide), polyEVC* terpolymer prepared from 13C-labeled carbon monoxide were also investigated using high temperature (120 °C) multidimensional (1D, 2D and 3D) NMR experiments on the same spectrometer. The NMR techniques used include 1D- 1H, 13C, 2D- gHSQC, gHMBC, gHSQC-TOCSY, 3D-gHCACX and 3D-gHCACX-HH-TOCSY NMR experiments. With 13C labeling of the polymer combined with high resolution multidimensional NMR experiments, pentad monomer sequence assignments can be made for the carbon monoxide (C)-centered pentads. The degradation of polyEVC* was also examined by 1D and 2D NMR. The NMR spectra show that [alpha], [beta]-unsaturated carbonyl groups are a degradation product in this terpolymer, arising from elimination of acetic acid from CV dyads.

Book Synopsis Multidimensional Solid-State NMR and Polymers by : Klaus Schmidt-Rohr
Download or read book Multidimensional Solid-State NMR and Polymers written by Klaus Schmidt-Rohr and published by Elsevier. This book was released on 2012-12-02 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: NMR spectroscopy is the most valuable and versatile analytical tool in chemistry. While excellent monographs exist on high-resolution NMR in liquids and solids, this is the first book to address multidimensional solid-state NMR. Multidimensional techniques enable researchers to obtain detailed information about the structure, dynamics, orientation, and phase separation of solids, which provides the basis of a better understanding of materials properties on the molecular level.Dramatic progress-much of it pioneered by the authors-has been achieved in this area, especially in synthetic polymers. Solid-state NMR now favorably competes with well-established techniques, such as light, x-ray, or neutron scattering, electron microscopy, and dielectric and mechanical relaxation.The application of multidimensional solid-state NMR inevitably involves use of concepts from different fields of science. This book also provides the first comprehensive treatment of both the new experimental techniques and the theoretical concepts needed in more complex data analysis. The text addresses spectroscopists and polymer scientists by treating the subject on different levels; descriptive, technical, and mathematical approaches are used when appropriate. It presents an overview of new developments with numerous experimental examples and illustrations, which will appeal to readers interested in both the information content as well as the potential of solid-state NMR. The book also contains many previously unpublished details that will be appreciated by those who want to perform the experiments. The techniques described are applicable not only to the study of synthetic polymers but to numerous problems in solid-state physics, chemistry, materials science, and biophysics. - Presents original theories and new perspectives on scattering techniques - Provides a systematic treatment of the whole subject - Gives readers access to previously unpublished material - Includes extensive illustrations

Download or read book Gas Phase NMR written by Karol Jackowski and published by Royal Society of Chemistry. This book was released on 2016-02-09 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the recent NMR studies with the application of gaseous molecules. Among the comprehensively discussed aspects of the area it includes in particular: new multinuclear experiments that deliver spectral parameters of isolated molecules and provide the most accurate values of nuclear magnetic shielding, isotropic spin–spin coupling and relaxation times; advanced, precise and correct theoretical descriptions of spectral parameters of molecules as well as the application of gas-phase NMR measurements to chemical analysis and medicine. The progress of research in these fields is enormous and has rapidly changed our knowledge and understanding of molecular parameters in NMR spectroscopy. For example, accurate studies of the shielding for isolated molecules allow the exact determination of nuclear magnetic dipole moments, the calculated values of spectral parameters can be verified by precise gas-phase NMR measurements, and the application of hyperpolarized noble gases provides excellent MRI pictures of lungs. Aimed at graduates and researchers in spectroscopy, analytical chemistry and those researching the applications of NMR in medicine, this book presents the connections between sophisticated experiments, the theory of magnetic parameters and the exploration of new methods in practice.

Book Synopsis Nondestructive Characterization of Materials by : Paul Höller
Download or read book Nondestructive Characterization of Materials written by Paul Höller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering structures for reliable function and safety have to be designed such that operational mechanical loads are compensated for by stresses in the components bearable by the materials used. Vhat is "bearable"? First of all it depends on the properties of the chosen materials as well as on several other parameters, e.g. temperature, corrosivity of the environment, elapsed or remaining serviceable life, unexpected deterioration of materials, whatever the source and nature of such deterioration may be: defects, loss of strength, embrittlement, wastage, etc. DEFECTS and PROPERTIES of materials currently determine loadability. Therefore in addition to nondestructive testing for defects there is also a need for nondestructive testing of properties. The third type of information to be supplied by nondestructive measurement pertains to STRESS STATES under OPERATIONAL LOADS, i.e. LOAD-INDUCED plus RESIDUAL STRESSES. Residual stresses normally cannot be calculated; they have to be measured nondestructively; well-approved elastomechanical finite element codes are available and used for calculating load-induced stresses; for redundancy and reliability, engineers, however, need procedures and instrumentation for experimental checks.
