This book was released on 1999 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: La spectroscopie infrarouge a été appliquée à l'étude des premiers états d'hydratation de plusieurs phyllosilicates 2:1, afin de caractériser l'organisation des molécules d'eau aux interfaces. Un montage expérimental mis au point spécialement dans le cadre de cette étude permet de réaliser des spectres IR en transmission sur des échantillons en film mince (1,3 mg) maintenu in situ à température et pression de vapeur d'eau contrôlées. L'examen du massif des vibrations de déformations des molécules d'eau, en particulier par décomposition graphique des spectres expérimentaux, permet de distinguer jusqu'à trois populations de molécules d'eau différentes. La comparaison entre des smectites comportant des cations compensateurs de nature différente, et (ou) des localisations de déficit de charge différentes, permet de confirmer l'influence des paramètres suivants sur l'organisation des premières molécules d'eau adsorbées, par ordre d'importance : 1. le pouvoir polarisant du cation compensateur, 2. le caractère auto-associatif des molécules d'eau par liaison hydrogène et leur dissociation, 3. la charge de la maille cristalline et la localisation des substitutions isomorphiques. La surface du feuillet n'est jamais à l'origine de l'hydratation des smectites, et des interactions sont possibles entre les molécules d'eau et les oxygènes basaux seulement en présence de substitutions tétraédriques. Par ailleurs, la localisation du cation compensateur permet d'expliquer l'évolution des vibrations des hydroxyles de la couche octaédrique. En outre, Les résultats acquis dans cette étude mettent en évidence la nécessité de prendre en compte dans les simulations numériques, la flexibilité et la dissociation des molécules d'eau aux interfaces.

This book was released on 2012-12-06 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades, the study of surfactants (detergents, for example) has been profoundly changed by ideas and techniques from physics, chemistry, and materials science. Among these are: self assembly; critical phenomena, scaling, and renormalization; high-resolution scattering, and magnetic resonance spectroscopy. This book represents the first systematic account of these new developments, providing both a general introduction to the subject as well as a review of recent developments. The book will be a very useful tool for the biophysist, biochemist or physical chemist working in the field of surfactants.

Download or read book III Nitride Semiconductors written by M.O. Manasreh and published by Elsevier. This book was released on 2000-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research advances in III-nitride semiconductor materials and device have led to an exponential increase in activity directed towards electronic and optoelectronic applications. There is also great scientific interest in this class of materials because they appear to form the first semiconductor system in which extended defects do not severely affect the optical properties of devices. The volume consists of chapters written by a number of leading researchers in nitride materials and device technology with the emphasis on the dopants incorporations, impurities identifications, defects engineering, defects characterization, ion implantation, irradiation-induced defects, residual stress, structural defects and phonon confinement. This unique volume provides a comprehensive review and introduction of defects and structural properties of GaN and related compounds for newcomers to the field and stimulus to further advances for experienced researchers. Given the current level of interest and research activity directed towards nitride materials and devices, the publication of the volume is particularly timely. Early pioneering work by Pankove and co-workers in the 1970s yielded a metal-insulator-semiconductor GaN light-emitting diode (LED), but the difficulty of producing p-type GaN precluded much further effort. The current level of activity in nitride semiconductors was inspired largely by the results of Akasaki and co-workers and of Nakamura and co-workers in the late 1980s and early 1990s in the development of p-type doping in GaN and the demonstration of nitride-based LEDs at visible wavelengths. These advances were followed by the successful fabrication and commercialization of nitride blue laser diodes by Nakamura et al at Nichia. The chapters contained in this volume constitutes a mere sampling of the broad range of research on nitride semiconductor materials and defect issues currently being pursued in academic, government, and industrial laboratories worldwide.
