Dieser Sonderband der Reihe "Topics in Stereochemistry" beschäftigt sich mit der Chiralität von Werkstoffen und der Bedeutung der Stereochemie für bestimmte Polymere, Flüssigkristalle und andere spezielle Materialien. Die Grundlage dafür bilden die ausführlich dargestellten Prinzipien der organischen Stereochemie. Das aktuellste derzeit erhältliche Buch zur Chiralität!
Molecular gels and fibrillar networks – a comprehensive guide to experiment and theory Molecular Gels: Materials with Self-Assembled Fibrillar Networks provides a comprehensive treatise on gelators, especially low molecular-mass gelators (LMOGs), and the properties of their gels. The structures and modes of formation of the self-assembled fibrillar networks (SAFINs) that immobilize the liquid components of the gels are discussed experimentally and theoretically. The spectroscopic, rheological, and structural features of the different classes of LMOGs are also presented. Many examples of the application of the principal analytical techniques for investigation of molecular gels (including SA...
Unter Zirkulardichroismus (CD) versteht man die spezifisch unterschiedliche Absorption von links- und rechtszirkular polarisiertem Licht durch bestimmte Moleküle. CD-Effekte lassen sich in Abhängigkeit von der Wellenlänge messen und spektroskopisch auswerten. Dieser Band erläutert Theorie und Anwendung der CD-Spektroskopie insbesondere für Biomoleküle. Ausführlich behandelt werden Anwendungen auf den Gebieten der organischen Stereochemie und der Biopolymere. Geschrieben von anerkannten Spezialisten! (06/00)
In the past several decades, molecular self-assembly has emerged as one of the main themes in chemistry, biology, and materials science. This book compiles and details cutting-edge research in molecular assemblies ranging from self-organized peptide nanostructures and DNA-chromophore foldamers to supramolecular systems and metal-directed assemblies
These essays are some of the most important papers co-written with my colleagues that supplement the discussion of CSCL research in the published books. These chapters take the discussion in specific directions. They begin with my general reflections on the importance of CSCL as a research field, situating my work on the VMT Project and my theory of group cognition within the field of CSCL. They describe the VMT research project, including its research approach, technology, pedagogy and analysis methods. Mostly, they discuss in some detail the findings that have emerged from the VMT Project about the nature of online interaction in that type of CSCL setting. The volume concludes with reports of work in the project and future directions that were underway.
Chiral materials have been studied in the Department of Chemistry at the University of Virginia for applications in areas like asymmetric catalysis, enantioselective fluorescent sensing, and optical/electrical materials. Optically active 1,1′-binaphthyl molecules are used to build novel chiral polymers, dendrimers, macrocycles, and acyclic molecules. 1,1′-Binaphthyl molecules are chosen because of their remarkably stable chiral configuration as well as their high asymmetric inductions in many processes.In this book, both the fundamental knowledge about the 1,1′-binaphthyl molecules and the synthesis of the structurally diverse 1,1′-binaphthyl-based materials are described. The applications of these materials in various fields are also discussed. This book will serve as a reference for graduate students as well as other professionals working in the related fields./a
The current volume is intended to provide an overview of the eLibrary and some documentation of my life as the author of these texts.
This book constitutes the refereed proceedings of the 19th International Conference on Database and Expert Systems Applications, DEXA 2008, held in Turin, Italy, in September 2008. The 74 revised full papers presented together with 1 invited paper were carefully reviewed and selected from 208 submissions. The papers are organized in topical sections on data privacy; temporal, spatial and high dimensional databases; semantic Web and ontologies; query processing; Web and information retrieval; mobile data and information; data and information streams; data mining algorithms; multimedia databases; data mining systems, data warehousing, OLAP; data and information semantics; XML databases; applications of database, information, and decision support systems; and schema, process and knowledge modelling and evolution.
This new book provides informative coverage of recent breakthroughs in vitamins and their ability to prevent disease, manage health issues, and treat chronic illness. It describes the beneficial effects of vitamins as nutraceuticals in treating cancer, for improving the immunity of patients with HIV and AIDS, for the treatment of tuberculosis, and for the management of infectious diseases, such as viral infections, microbial infections, and COVID-19. The functional activity of vitamins in brain health and obesity management is also explored for the management, prevention, and delay of hypertension and related problems. The volume also covers vitamins that play a role in neurodegenerative diseases as well as those that can be used for weight loss and obesity, blindness and vision issues, baldness, and skincare issues.
