This book was released on 2018-06-05 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents information about several topics in the field of electron paramagnetic resonance (EPR) study of carbon-containing nanomaterials. It introduces the reader to an array of experimental and theoretical approaches for the analysis of paramagnetic centers (dangling bonds, interface defects, vacancies, and impurities) usually observed in modern carbon-containing materials such as nanographites, graphene, disordered onion-like carbon nanospheres (DOLCNS), single-walled carbon nanotubes (SWCNTs), multi-walled carbon nanotubes (MWCNT), graphene oxide (GO), reduced graphene oxide (rGO), nanodiamonds, silicon carbonitride (SiCN) and silicon carbide (SiC) based composites and thin films. In particular, the book describes in detail: • The fundamentals of EPR spectroscopy and its application to the carbon-containing materials; • The resolution of the EPR signals from different species in carbon materials; • EPR characterization of spin dynamics in carbon nanomaterials; • Magnetic properties of DWCNTs and MWCNTs polymer composites; • EPR investigations on GO, rGO and CNTs with different chemical functionalities; • EPR spectroscopy of semiconducting SWCNTs thin films and their transistors; • In-situ EPR investigations of the oxygenation processes in coal and graphene materials; • The two-temperature EPR measurement method applied to carbonaceous solids; • Characterization of impurities in nanodiamonds and SiC nanomaterials and related size effects by CW and pulse EPR techniques; • Application of multifrequency EPR to the study of paramagnetic defects in a-Si1-xCx:H thin films and a-SiCxNy based composites. This volume is a useful guide for researchers interested in the EPR study of paramagnetic centers in the carbon-containing thin films, nanomaterials, ceramics, etc. It is also a valuable teaching tool at graduate and postgraduate levels for advanced courses in analytical chemistry, applied sciences and spectroscopy.

Download or read book Carbon and Deuterium Nuclear Magnetic Resonance in Solids written by and published by . This book was released on 1976 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Chapter I we present the results on a study of cross polarization dynamics, between protons and carbon-13 in adamantane, by the direct observation of the dilute, carbon-13, spins. These dynamics are an important consideration in the efficiency of proton enhancement double-resonance techniques and they also provide good experimental models for statistical theories of cross relaxation. In order to test these theories we present a comparison of the experimental and theoretical proton dipolar fluctuation correlation time [tau]{sub c}, which is experimentally 110 ± 15 [mu]sec and theoretically 122 [mu]sec for adamantane. These double resonance considerations provide the background for extensions to deuterium and double quantum effects discussed in Chapter II. In Chapter II an approach to high resolution nmr of deuterium in solids is described. The m = 1 → -1 transition is excited by a double quantum process and the decay of coherence Q([tau]) is monitored. Fourier transformation yields a deuterium spectrum devoid of quadrupole splittings and broadening. If the deuterium nuclei are dilute and the protons are spin decoupled, the double-quantum spectrum is a high resolution one and yields information on the deuterium chemical shifts [Delta][omega]. The relationship Q([tau]) ≈ cos 2[Delta][omega][tau] is checked and the technique is applied to a single crystal of oxalic acid dihydrate enriched to ≈ 10% in deuterium. The carboxyl and the water deuterium shifts are indeed resolved and the anisotropy of the carboxyl shielding tensor is estimated to be [Delta][sigma] = 32 ± 3 ppm. A complete theoretical analysis is presented. The extension of cross relaxation techniques, both direct and indirect, to proton-deuterium double resonance is also described. The m = 1 → -1 double quantum transition and the m = ± 1 → 0 single quantum transitions may all be polarized and we present the derivation of the Hartmann-Hahn cross polarization conditions for each case. In addition the dynamics of the double quantum process, for monodeutero benzene are discussed, giving proton dipolar fluctuation correlation times, and spin heat capacities for the double quantum transition.

Download or read book Multinuclear Magnetic Resonance in Liquids and Solids Chemical Applications written by P. Granger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of this NATO school was born during philosophical discussions with Dr Brevard on the present and future of NMR during a night walk under the palm trees in Biskra during a seminar held in this oasis. It was clear for us that the recent progress in the field of NMR, especially inverse spectroscopy and the development of MAS, was opening new perspectives for chemists. We realised also that organometallic and inorganic chemists were not clearly informed about the potentialities of all the new methods. NA TO, with its summer schools, was offering a good opportunity to propose to the chemical community a session where those problems would be largely developped. This School is then the prolongation of the two previous ones: Palermo in 1976 on "the less receptive nuclei" and Stirling in 1982 on "the multinuclear approach to NMR spectroscopy" . It was divided into two sub-sessions: NMR in the liquid state and NMR in the solid state. This is reflected in the book organization. As indicated by the title of this School, we were mainly concerned with the methodological aspects of multinuclear NMR. If many examples are given, they appear only as a support for the understanding of the theory or in explanation of some practical aspects of the different experiments. Each domain is introduced by a lecture which presents selected examples.

Available in PDF, EPUB and Kindle. Book excerpt: Written by distinguished researchers, the long-running Chemistry and Physics of Carbon series provides a comprehensive and critical overview of carbon materials in terms of molecular structure, intermolecular relationships, bulk and surface properties, and their behavior in current and emerging applications. Volume 31 not only retains the high-quality content and reputation of previous volumes, but also complements them with reliable and timely coverage of the latest advances in the field. Maintaining the high level established by its predecessors, this book contains a prestigious and authoritative series of review chapters covering both chemistry and physics of carbon. The book examines properties and behavior of carbon materials ranging from coal to graphite, from activated carbons, chars, cokes, and carbon blacks to carbon fibers, fullerenes, nanotubes, and graphene. It complements previous volumes in the series by presenting updated information on ‘disordered’ carbons, a complex field that impacts nearly all aspects of carbon materials research. It includes a chapter on novel methods of characterization of carbon materials using ever more powerful techniques, as well as a chapter on the use of carbon materials in photocatalysis, a fast-moving and potentially exciting application. Emphasizing key experimental results and practical aspects, as well as important theoretical issues in every chapter, Volume 31 is a vital resource for those engaged in developing new technologies in a wide range of applicability of traditional and novel carbon materials from drug delivery to energy storage and conversion.
