Download or read book Metallofoldamers written by Galia Maayan and published by John Wiley & Sons. This book was released on 2013-01-18 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallofoldamers are oligomers that fold into three-dimensional structures in a controlled manner upon coordination with metal ions. Molecules in this class have shown an impressive ability to form single-handed helical structures and other three-dimensional architectures. Several metallofoldamers have been applied as sensors due to their selective folding when binding to a specific metal ion, while others show promise for applications as responsive materials on the basis of their ability to fold and unfold upon changes in the oxidation state of the coordinated metal ion, and as novel catalysts. Metallofoldamers: From Helicates to Biomimetic Architectures describes the variety of interactions between oligomers and metal species, with a focus on non-natural synthetic molecules. Topics covered include: the major classes of foldamers and their folding driving force metalloproteins and metalloenzymes helicates: self-assembly, structure and applications abiotic metallo-DNA metallo-PNA and iDNA metallopeptides interactions of biomimetic oligomers with metal ions applications of metallofoldamers
Download or read book RST 12 written by Académie des sciences, and published by Lavoisier. This book was released on 2000 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: La science et la technologie sont portées actuellement par un essor économique fort, par des révisions stratégiques globales liées à la fin de la guerre froide et à la mondialisation de l'économie et, surtout, par des découvertes majeures dans les sciences et techniques de l'information et de la communication et dans les sciences de la vie. Dans ce paysage très évolutif, le gouvernement français, à l'occasion du Comité interministériel de la recherche scientifique et technique du 15 juillet 1998, a retenu la proposition du Ministre de l'Education nationale, de la Recherche et de la Technologie de confier à l'Académie des sciences le soin d'établir un rapport sur l'état de la science et de la technologie en France. Ce rapport est la synthèse de 11 rapports thématiques qui ont été remis au ministre le 27 juillet 2000. Le rapprochement des disciplines et des techniques scientifiques dans l'abord des problèmes et dans l'étude des systèmes complexes devrait inciter à ce qu'un accent plus net soit mis sur des projets pluridisciplinaires développés entre plusieurs organismes de recherches ainsi qu'avec des universités et des entreprises. Cela devrait impliquer aussi une vision nouvelle dans les formations de l'enseignement supérieur, dans la politique des grands équipements, assortie d'une facilitation de la mobilité des chercheurs, tant au sein de l'hexagone qu'à l'extérieur. La France doit affirmer davantage sa participation aux grands " programmes-cadres " de l'Union européenne, qui ont déjà contribué au décloisonnement des équipes, même si l'Académie reconnaît l'urgence d'une simplification des procédures et la nécessité d'une intervention plus directe des scientifiques dans l'établissement et le suivi de ces programmes. Par ailleurs, il apparaît nécessaire que la communauté scientifique française prenne mieux en compte les enjeux sociétaux et les problèmes éthiques dans un contexte d'ensemble où l'image de la science perd parfois de sa force. Au-delà des propositions liées à chacune des disciplines traitées, les auteurs formulent des recommandations visant à adapter le système français de recherche/développement et d'enseignement aux nouvelles données scientifiques et économiques.

Available in PDF, EPUB and Kindle. Book excerpt: Organic Reaction Mechanisms 2017, the 53rd annual volume in this highly successful and unique series, surveys research on organic reaction mechanisms described in the available literature dated 2017. The following classes of organic reaction mechanisms are comprehensively reviewed: • Reaction of Aldehydes and Ketones and their Derivatives • Reactions of Carboxylic, Phosphoric, and Sulfonic Acids and their Derivatives • Oxidation and Reduction • Carbenes and Nitrenes • Nucleophilic Aromatic Substitution • Electrophilic Aromatic Substitution • Carbocations • Nucleophilic Aliphatic Substitution • Carbanions and Electrophilic Aliphatic Substitution • Elimination Reactions • Polar Addition Reactions • Cycloaddition Reactions • Molecular Rearrangements An experienced team of authors compile these reviews every year, so that the reader can rely on a continuing quality of selection and presentation.
Download or read book Heterogeneous Catalysis and Fine Chemicals written by J. Barrault and published by Elsevier. This book was released on 1988-08-01 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recession in the traditional heavy industries along with the development of advanced technologies in all the industrial countries has meant that the impact of heterogeneous catalysis in the synthesis of fine chemicals is becoming increasingly noticeable. The first International Symposium on Heterogeneous Catalysis and Fine Chemicals is to be seen in this perspective. Organised by the Laboratory of Catalysis in Organic Chemistry of the University of Poitiers within the framework of the International Symposia of the `Centre National de la Recherche Scientifique' (CNRS), the symposium provided an opportunity for contact between academic researchers and manufacturers, users (or potential users) of solid catalysts for fine chemical synthesis.Two panels of industrial and academic researchers - one on selective hydrogenation, the other on selective synthesis of substituted aromatics - showed that heterogeneous catalysis already plays a significant role in fine organic chemistry. The main topics of the symposium were introduced in six plenary lectures and three invited communications, maintaining a balance between the industrial and the academic points of view. Some 60 research papers were submitted from which the Scientific Committee selected the 35 communications (oral or poster) which fitted most closely the theme of the symposium. All are reproduced in full in this Proceedings volume.

Download or read book Advanced Organic Chemistry written by Francis A. Carey and published by Springer Science & Business Media. This book was released on 2007-06-27 with total page 1216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two-part, fifth edition of Advanced Organic Chemistry has been substantially revised and reorganized for greater clarity. The material has been updated to reflect advances in the field since the previous edition, especially in computational chemistry. Part A covers fundamental structural topics and basic mechanistic types. It can stand-alone; together, with Part B: Reaction and Synthesis, the two volumes provide a comprehensive foundation for the study in organic chemistry. Companion websites provide digital models for study of structure, reaction and selectivity for students and exercise solutions for instructors.
Download or read book Roald Hoffmann on the Philosophy Art and Science of Chemistry written by Jeffrey Kovac and published by Oxford University Press. This book was released on 2012-02-01 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nobel laureate Roald Hoffmann's contributions to chemistry are well known. Less well known, however, is that over a career that spans nearly fifty years, Hoffmann has thought and written extensively about a wide variety of other topics, such as chemistry's relationship to philosophy, literature, and the arts, including the nature of chemical reasoning, the role of symbolism and writing in science, and the relationship between art and craft and science. In Roald Hoffmann on the Philosophy, Art, and Science of Chemistry, Jeffrey Kovac and Michael Weisberg bring together twenty-eight of Hoffmann's most important essays. Gathered here are Hoffmann's most philosophically significant and interesting essays and lectures, many of which are not widely accessible. In essays such as "Why Buy That Theory," "Nearly Circular Reasoning," "How Should Chemists Think," "The Metaphor, Unchained," "Art in Science," and "Molecular Beauty," we find the mature reflections of one of America's leading scientists. Organized under the general headings of Chemical Reasoning and Explanation, Writing and Communicating, Art and Science, Education, and Ethics, these stimulating essays provide invaluable insight into the teaching and practice of science.
