ON ENTEND PAR MILIEU HETEROGENE (COMPOSITE) TOUT MILIEU OBTENU PAR L'ASSOCIATION DE PLUSIEURS SUBSTANCES DE NATURE DIFFERENTE. LA CONNAISSANCE DU MILIEU COMPOSITE S'APPUIE, D'UNE PART SUR LA CARACTERISATION DU MATERIAU PAR LA MESURE DE LA SUSCEPTIBILITE MAGNETIQUE COMPLEXE ET D'AUTRE PART SUR LA MODELISATION DE CE MILIEU A L'AIDE D'OUTILS MATHEMATIQUES. POUR LA CARACTERISATION EN REGIME QUASI-STATIQUE, NOUS DEVELOPPONS PLUSIEURS TECHNIQUES DE MESURE, FAIBLE ET LARGE BANDES ADAPTEES A DES ECHANTILLONS DE FORME ET DE NATURE DIFFERENTES (BATONNETS, DISQUES, ANNEAUX; SOLIDE OU LIQUIDE), TOUTES BASEES SUR LA METHODE DU TRANSFORMATEUR. CES DISPOSITIFS DE MESURE, TRES SENSIBLES (METHODES DE LA TRANSITION FERROMAGNETIQUE/PARAMAGNETIQUE ET DE LA BOBINE PLATE) OU A USAGE INDUSTRIEL (METHODE DU POT MAGNETIQUE) OU A TRES LARGE BANDE (METHODE DU TRANSFORMATEUR COAXIAL: 10 HZ: 200 MHZ) NOUS OFFRENT UN LARGE EVENTAIL DE MOYENS DE CARACTERISATION DES MATERIAUX MAGNETIQUES HETEROGENES DANS LE DOMAINE DES FREQUENCES BASSES ET MOYENNES. LA CARACTERISATION HYPERFREQUENCE QUI S'ETEND DE 300 KHZ A 5 GHZ, EST REALISEE PAR UNE EXTENSION DE LA METHODE DU TRANSFORMATEUR COAXIAL PRECEDEMMENT CITEE. LA LIMITE FREQUENTIELLE DE VALIDITE DU DISPOSITIF DE MESURE EST DISCUTEE EN FONCTION DES DIMENSIONS DE LA CELLULE ET DE LA NATURE DU MATERIAU A ETUDIER. IL EST MONTRE QUE LES MATERIAUX MAGNETIQUES COMPOSITES SONT LE SIEGE D'EFFETS DEMAGNETISANTS QUI LEUR APPORTENT DES AVANTAGES INDISCUTABLES, PAR RAPPORT AUX MATERIAUX MASSIFS (FERRITES), SUR LE PLAN DE LA STABILITE THERMIQUE ET CELUI DU COMPORTEMENT DYNAMIQUE. LA MEILLEURE CONNAISSANCE DU MILIEU MAGNETIQUE HETEROGENE NECESSITE SA MODELISATION. IL EXISTE DANS LA LITTERATURE SCIENTIFIQUE PRES DE 40 MODELES MATHEMATIQUES. NOUS PRESENTONS DEUX D'ENTRE EUX: LE MODELE DE MAXWELL-GARNETT ET CELUI DE BRUGGEMAN. LES RESULTATS EXPERIMENTAUX SONT NETTEMENT EN FAVEUR DU SECOND

Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Available in PDF, EPUB and Kindle. Book excerpt: Quartz, zeolites, gemstones, perovskite type oxides, ferrite, carbon allotropes, complex coordinated compounds and many more -- all products now being produced using hydrothermal technology. Handbook of Hydrothermal Technology brings together the latest techniques in this rapidly advancing field in one exceptionally useful, long-needed volume.The handbook provides a single source for understanding how aqueous solvents or mineralizers work under temperature and pressure to dissolve and recrystallize normally insoluble materials, and decompose or recycle any waste material. The result, as the authors show in the book, is technologically the most efficient method in crystal growth, materials processing, and waste treatment. The book gives scientists and technologists an overview of the entire subject including: À Evolution of the technology from geology to widespread industrial use. À Descriptions of equipment used in the process and how it works.À Problems involved with the growth of crystals, processing of technological materials, environmental and safety issues.À Analysis of the direction of today's technology. In addition, readers get a close look at the hydrothermal synthesis of zeolites, fluorides, sulfides, tungstates, and molybdates, as well as native elements and simple oxides. Delving into the commercial production of various types, the authors clarify the effects of temperature, pressure, solvents, and various other chemical components on the hydrothermal processes.

Book excerpt: The molecular mechanisms underlying the fact that a crystal can take a variety of external forms is something we have come to understand only in the last few decades. This is due to recent developments in theoretical and experimental investigations of crystal growth mechanisms. Morphology of Crystals is divided into three separately available volumes. Part A contains chapters on roughening transition; equilibrium form; step pattern theory; modern PBC; and surface microtopography. This part provides essentially theoretical treatments of the problem, particularly the solid-liquid interface. Part B contains chapters on ultra-fine particles; minerals; transition from polyhedral to dendrite; theory of dendrite; and snow crystals. All chapters are written by world leaders in their respective areas, and some can be seen as representing the essence of a life's work. This is the first English-language work which covers all aspects of the morphology of crystals - a topic which has attracted top scientific minds for centuries. As such, it is indispensable for anyone seeking an answer to a question relating to this fascinating problem: mineralogists, petrologists, crystallographers, materials scientists, workers in solid-state physics and chemistry, etc. In Parts A: Fundamentals and B: Fine Particles, Minerals and Snow equilibrium and kinetic properties of crystals are generally approached from an `atomistic' point of view. In contrast, Part C: The Geometry of Crystal Growth follows the alternative and complementary `geometrical' description, where bulk phases are considered as continuous media and their interfaces as mathematical surfaces with orientation-dependent properties. Equations of motion for a crystal surface are expressed in terms of vector and tensor operators working on surface free energy and growth rate, both expressed as functions of surface orientation and driving force, or `affinity' for growth. This approach emphasizes the interrelation between equilibrium and kinetic behavior. Part 1 establishes the theoretical framework. Part 2 gives a construction toolbox for explicit (analytic) functions. An extra chapter is devoted to experimental techniques for measuring such functions: a new approach to sphere growth experiments. The emphasis throughout is on principles and new concepts. Audience: Advanced readers familiar with traditional aspects of crystal growth theory. Can be used as the basis for an advanced course, provided supplementation is provided in the areas of atomistic models of the advancing surface, diffusion fields, etc.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.

Book excerpt: This open access book collects the contributions of the seventh school on Magnetism and Synchrotron Radiation held in Mittelwihr, France, from 7 to 12 October 2018. It starts with an introduction to the physics of modern X-ray sources followed by a general overview of magnetism. Next, light / matter interaction in the X-ray range is covered with emphasis on different types of angular dependence of X-ray absorption spectroscopy and scattering. In the end, two domains where synchrotron radiation-based techniques led to new insights in condensed matter physics, namely spintronics and superconductivity, are discussed. The book is intended for advanced students and researchers to get acquaintance with the basic knowledge of X-ray light sources and to step into synchrotron-based techniques for magnetic studies in condensed matter physics or chemistry.

Book excerpt: Advances in the synthesis of new materials with often complex, nano-scaled structures require increasingly sophisticated experimental techniques that can probe the electronic states, the atomic magnetic moments and the magnetic microstructures responsible for the properties of these materials. At the same time, progress in synchrotron radiation techniques has ensured that these light sources remain a key tool of investigation, e.g. synchrotron radiation sources of the third generation are able to support magnetic imaging on a sub-micrometer scale. With the Fifth Mittelwihr School on Magnetism and Synchrotron Radiation the tradition of teaching the state-of-the-art on modern research developments continues and is expressed through the present set of extensive lectures provided in this volume. While primarily aimed at postgraduate students and newcomers to the field, this volume will also benefit researchers and lecturers actively working in the field.
