Book Description
Semiconductor nanocrystals, with unique size-dependent properties, give promise for successful innovation of new technologies including solid-state lighting and biological labeling. Therefore, characterization of the surfaces, interfaces and associated reconstruction in these materials becomes crucial for an understanding of structure-function relationships essential to this development. In this dissertation, powerful solid-state nuclear magnetic resonance (NMR) techniques, such as cross-polarization magic angle spinning (CPMAS), spin-echo, and two dimensional (2D) heteronuclear chemical shift correlation (HETCOR) experiments are utilized to probe these various regions in CdSe and InGaP nanocrystals. These experiments reveal fundamental structural information, including insight into atomic vacancies, discrete particle reconstruction with size, oxidation, passivation, and the nature and molecular order of the surface, near surface and core species. This knowledge gives rise to valuable direct correlations of the structural molecular models of reconstruction with the physical properties of CdSe and InGaP nanomaterials.

Book Description
Properties and applications of high surface area materials depend on interfacial phenomena, including diffusion, sorption, dissolution, solvation, surface reactions, catalysis, and phase transitions. Among the physicochemical methods that give useful information regarding these complex phenomena, nuclear magnetic resonance (NMR) spectroscopy is the most universal, yielding detailed structural data regarding molecules, solids, and interfaces. Nuclear Magnetic Resonance Studies of Interfacial Phenomena summarizes NMR research results collected over the past three decades for a wide range of materials—from nanomaterials and nanocomposites to biomaterials, cells, tissues, and seeds. This book describes the applications of important new NMR spectroscopic methods to a variety of useful materials and compares them with results from other techniques such as adsorption, differential scanning calorimetry, thermally stimulated depolarization current, dielectric relaxation spectroscopy, infrared spectroscopy, optical microscopy, and small-angle and wide-angle x-ray scattering. The text explores the application of NMR spectroscopy to examine interfacial phenomena in objects of increasing complexity, beginning with unmodified and modified silica materials. It then describes properties of various mixed oxides with comparisons to individual oxides and also describes carbon materials such as graphite and carbon nanotubes. Chapters deal with carbon–mineral hybrids and their mosaic surface structures, and interfacial phenomena at the surface of natural and synthetics polymers. They also explore a variety of biosystems, which are much more complex, including biomacromolecules (proteins, DNA, and lipids), cells and tissues, and seeds and herbs. The authors cover trends in interfacial phenomena investigations, and the final chapter describes NMR and other methods used in the book. This text presents a comprehensive description of a large array of hard and soft materials, allowing the analysis of the structure–property relationships and generalities on the interfacial behavior of materials and adsorbates.

Book Description
Why to apply solid-state NMR? - By now, we should have learned that NMR is mainly used for the study of molecules in solution, while x-ray diffraction is the method of choice for solids. Based on this fact, the two recent 'NMR-Nobelprizes' went indeed into the liquid phase: my own one eleven years ago, and particularly the most recent one to Kurt Wuthrich. His prize is beyond any doubts very well justified. His contribution towards the study of biomolecules in solution, in their native (or almost native) environment is truly monumental. We all will profit from it indirectly when one of our future diseases will be cured with better drugs, based on the insightful knowledge gained through liquid-state NMR. Two fields of NMR are still left out of the Nobel Prize game: magnetic reso nance imaging (MRI) and solid-state NMR. The disrespect for MRI in Stockholm is particularly difficult to understand; but this is not a subject to be discussed at the present place. Solid-state NMR is the third of the three great fields of NMR, powerful already today and very promising for the near future.

Book Description
Solid State NMR A thorough and comprehensive textbook covering the theoretical background, experimental approaches, and major applications of solid-state NMR spectroscopy Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful non-destructive technique capable of providing information about the molecular structure and dynamics of molecules. Alongside solution-state NMR, a well-established technique to study chemical structures and investigate physico-chemical properties of molecules in solutions, solid-state NMR (SSNMR) offers many exciting possibilities for the analysis of solid and soft materials across scientific fields. SSNMR shows unique capabilities for a detailed investigation of structural and dynamic properties of materials over wide space and time ranges. For this reason, and thanks to significant advances in the past several years, the application of SSNMR to materials is rapidly increasing in disciplines such as chemistry, physics, and materials and life sciences. Solid State NMR: Principles, Methods, and Applications offers a systematic introduction to the theory, methodological concepts, and major experimental methods of SSMR spectroscopy. Exploring the unique potential of SSNMR for the structural and dynamic characterization of soft and either amorphous or crystalline solid materials, this comprehensive textbook provides foundational knowledge and recent developments of SSNMR, covering physical and theoretical background, experimental methods, and applications to pharmaceuticals, polymers, inorganic and hybrid materials, liquid crystals, and model membranes. Written by two expert authors to ensure a clear and consistent presentation of the subject, this textbook: Includes a brief introduction to the historical aspects and broad theoretical background of solid-state NMR spectroscopy Provides helpful illustrations to explain the various SSNMR concepts and methods Features accessible descriptive text with self-consistent use of quantum mechanics Covers the experimental aspects of SSNMR spectroscopy and in particular a description of many useful pulse sequences Contains references to relevant literature Solid State NMR: Principles, Methods, and Applications is the ideal textbook for university courses on SSNMR, advanced spectroscopies, and a valuable single-volume reference for spectroscopists, chemists, and researchers in the field of materials.
