Buch. Condizione: 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 (NEPP) that are present in the diet, this book will improve our knowledge of dietary intakes and physiological properties of NEPP ensuring a better understanding of their potential health effects. With global appeal, this will be the first book dedicated to raising the profile of this important area. Summarising the current knowledge in the field, the book will direct further research for food chemists, scientists and nutritionists looking for a new perspectives. …

Buch. Condizione: 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.The book starts by addressing the challenges of water splitting followed by chapters on the theoretical design of PEC materials and their computational screening. The book then explores advances in identifying reaction intermediates in PEC materials as well as developments in solution processed photoelectrodes, photocatalyst sheets, and bipolar membranes. The final part of the book focuses on systems analysis, which lays out a roadmap of where researchers hope the fundamental research will lead us.Edited by world experts in the field of solar fuels, the book provides a comprehensive overview of photoelectrochemical water splitting, from theoretical aspects to systems analysis, for the energy research community. …

Buch. Condizione: Neu. Neuware - Solid-state NMR covers an enormous range of material types and experimental 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.This book is an ideal complement to existing introductory texts and is 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.…

Buch. Condizione: 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 (MIPs) that have a selectivity close to that revealed by natural receptors.The book summarizes the latest developments and applications of molecular imprinting for selective chemical sensing with each chapter devoted to different analytical applications of molecularly imprinted polymers. Specific chapters include: designing of molecular cavities aided by computational modelling, application of molecularly imprinted polymers for separation as well as sensing of pharmaceuticals and nucleotides. The book is suitable for academics, postgraduates, and industrial researchers active in analytical chemistry, synthetic organic chemistry, molecular recognition, electrochemistry, and spectroscopy.…

Buch. Condizione: 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. This book details the analysis of a range of molecular systems by light-based techniques relevant to forensic science, as well as the negative effects of light in the degradation of forensic evidence, such as the breakage of DNA linkages during DNA profiling. The introductory chapters explain how chemiluminescence and fluorescence can be used to visualise samples and the advantages and limitations of available technologies. They also discuss the limitations of our knowledge about how light could alter the physical nature of materials, for example by breaking DNA linkages during DNA profiling or by modifying molecular structures of polymers and illicit drugs. The book then explains how to detect, analyse and interpret evidence from materials such as illicit drugs, agents of bioterrorism, and textiles, using light-based techniques from microscopy to surface enhanced Raman spectroscopy. Edited by active photobiological and forensic scientists, this book will be of interest to students and researchers in the fields of photochemistry, photobiology, toxicology and forensic science.…
