Buch. Zustand: Neu. Neuware - Solid-state NMR covers an enormous range of material types and experimental techniques. Although the basic instrumentation and techniques of solids NMR are readily accessible, there can be significant barriers, even for existing experts, to exploring the bewildering array of more sophisticated techniques. In this unique volume, a range of experts in different areas of modern solid-state NMR explain about their area of expertise, emphasising the 'practical aspects' of implementing different techniques, and illustrating what questions can and cannot be addressed. Later chapters address complex materials, showing how different NMR techniques discussed in earlier chapters can be brought together to characterise important materials types. The volume as a whole focusses on topics relevant to the developing field of 'NMR crystallography' - the use of solids NMR as a complement to diffraction crystallography. This book is an ideal complement to existing introductory texts and reviews on solid-state NMR. New researchers wanting to understand new areas of solid-state NMR will find each chapter to be the equivalent to spending time in the laboratory of an internationally leading expert, learning the hints and tips that make the difference between knowing about a technique and being ready to put it into action. With no equivalent on the market, it will be of interest to every solid-state NMR researcher (academic and postgraduate) working in the chemical sciences.

Buch. Zustand: Neu. Neuware - Polyphenols and carotenoids are abundant in fruits, vegetables, herbs and spices, and beverages, such as tea, cocoa and wine providing health-related benefits and antioxidant properties. Focusing on non-extractable polyphenols and carotenoids that are present in the diet, this book will improve our knowledge of dietary intakes and physiological properties ensuring a better understanding of their potential health effects.

Buch. Zustand: Neu. Neuware - There is great interest in the preparation of synthetic receptor-based recognition units for cheap, robust, economic, and selective chemical sensors. Molecular imprinting provides the technology to prepare these synthetic units. There are still more and more syntheses of artificial molecular recognition constructs using analytes or their close structural analogues as templates for molecular imprinting. Stability of complexes of these constructs with the target analytes are often similar to those of biological receptors. Therefore, subsequent polymerization of these complexes results in molecularly imprinted polymers that have a selectivity close to that revealed by natural receptors.

Buch. Zustand: Neu. Neuware - Lignin, an aromatic biopolymer found in plant cell walls, is a key component of lignocellulosic biomass and generally utilized for heat and power. However, lignin's chemical composition makes it an attractive source for biological and catalytic conversion to fuels and chemicals. Bringing together experts from biology, catalysis, engineering, analytical chemistry, and techno-economic/life-cycle analysis, Lignin Valorization presents a comprehensive, interdisciplinary picture of how lignocellulosic biorefineries could potentially employ lignin valorization technologies.

Buch. Zustand: Neu. Neuware - Tremendous research is taking place to make photoelectrochemical (PEC) water splitting technology a reality. Development of high performance PEC systems requires an understanding of the theory to design novel materials with attractive band gaps and stability. Focusing on theory and systems analysis, Advances in Photoelectrochemical Water Splitting provides an up-to-date review of this exciting research landscape.

Buch. Zustand: Neu. Neuware - The identification and quantification of material present and collected at a crime scene are critical requirements in investigative analyses. Forensic analysts use a variety of tools and techniques to achieve this, many of which use light. Light is not always the forensic analyst's friend however, as light can degrade samples and alter results.

Buch. Zustand: Neu. Neuware - Light induced chemical and physical processes in small organic-/inorganic-/bio-molecules have been a subject of experimental and theoretical research for several decades. Recent advances in high resolution spatio-temporal techniques have offered detailed understanding of excited state processes in small molecules. In sharp contrast, however, information on electronic processes in biomolecules such as isolated proteins and DNA (and their complexes) is still in its infancy. Though extremely complicated to uncover, knowledge of photo-excited state processes of such biomolecules in the cellular/biological context is the eventual goal of scientists working in these areas.
