This book proposes a thorough introduction for a varied audience. The reader will master London theory and the Pippard equations, and go on to understand type I and type II superconductors (their thermodynamics, magnetic properties, vortex dynamics, current transport...), Cooper pairs and the results of BCS theory. By studying coherence and flux quantization he or she will be lead to the Josephson effect which, with the SQUID, is a good example of the applications. The reader can make up for any gaps in his knowledge with the use of the appendices, follow the logic behind each model, and assimilate completely the underlying concepts. Approximately 250 illustrations help in developing a thoro...
Physical techniques such as X-ray crystallography, IR spectroscopy and solution-phase NMR spectroscopy have played key roles in the development of supramolecular chemistry. In recent years other spectroscopic techniques have been applied, expanding the range of information obtainable. The most widely used technique is solid-state NMR spectroscopy but techniques such as neutron scattering and NQR spectroscopy can yield significant information. Computational approaches are now becoming powerful complementary methods to experimental techniques and this book reviews the application of these methods to supramolecular systems. The ten chapters provide up-to-date information on the applications of ...

Since its creation in 1884, Engineering Index has covered virtually every major engineering innovation from around the world. It serves as the historical record of virtually every major engineering innovation of the 20th century. Recent content is a vital resource for current awareness, new production information, technological forecasting and competitive intelligence. The world?s most comprehensive interdisciplinary engineering database, Engineering Index contains over 10.7 million records. Each year, over 500,000 new abstracts are added from over 5,000 scholarly journals, trade magazines, and conference proceedings. Coverage spans over 175 engineering disciplines from over 80 countries. Updated weekly.
La supraconductivité fait rêver, surtout depuis la découverte de son existence à des températures relativement accessibles. Ses applications sont déjà notables (Imagerie par Résonance magnétique, futur ITER, NEUROSPIN, SQUID...) et des projets plus futuristes se développent (transport de courant, train en lévitation, moteurs). Le lecteur pourra s’initier à la théorie de London et aux équations de Pippard, puis étudier les supraconducteurs de type I et de type II (thermodynamique, magnétisme, dynamique de vortex, transport de courant...), les paires de Cooper et les résultats de la théorie BCS. L’étude de la cohérence et de la quantification du flux conduit à l’effe...
Les bibliothécaires et documentalistes exercent, aujourd'hui, une profession qui s'est beaucoup transformée ces dernières années. En effet, des millions de notices ont été rassemblées en France, dont certaines sont déjà accessibles sur Minitel ou Internet, ou disponibles sur CD-ROM. De nombreux « chantiers » sont encore nécessaires, pour satisfaire les attentes d'ouvertures de grands catalogues collectifs destinés à des communautés de chercheurs : - donner accès à l'ensemble des collections à travers la diversité des supports ; - fournir une information plus pointue et organisée ; - identifier les documents issus de l'édition électronique. Ce recueil répond aux besoins...
