Book Synopsis Approche expérimentale et théorique de la diffusion Raman exaltée by : Victor Le Nader
Download or read book Approche expérimentale et théorique de la diffusion Raman exaltée written by Victor Le Nader and published by . This book was released on 2010 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse s'articule autour des phénomènes d'exaltation de la diffusion Raman grâce aux propriétés optiques des métaux nobles (Or et Argent). Des expériences de Spectroscopie Raman Exaltée de Surface (SERS : Surface Enhanced Raman Spectroscopy) et de Spectroscopie Raman Exaltée par sonde locale (TERS : Tip Enhanced Raman Spectroscopy) ont permis l'exploration des ces phénomènes. Le premier volet de ce travail a consisté en la préparation de substrats "SERS-actifs" et en l'analyse de leurs pouvoir exaltant. Trois types de substrats ont été élaborés au laboratoire afin d'étudier les paramètres d'influence (structuration de la surface, longueur d'onde et polarisation de la lumière incidente, nature du métal, etc...). Le second volet du travail a été consacré à la mise en place d'un dispositif TERS. La conception des pointes métalliques a fait l'objet d'une attention particulière. De plus, un module a été élaboré afin d'associer un système de nano-positionnement de la pointe à un Raman confoncal commercial. Ce module a aussi été conçu pour permettre de focaliser le faisceau laser à l'extrémité de la nano-sonde métallique. La conception des outils ainsi que la compréhension des résultats expérimentaux sont corrélés à une analyse numérique. Les sources électromagnétiques (plasmons de surface et effet de pointe) de l'amplification de la diffusion Raman sont étudiées avec l'appui de simulations numériques par la méthode des éléments finis. Enfin les aspects chimiques des phénomènes d'exaltation sont abordés par DFT (Density Functiunal Theory).

Download or read book Silicate Melts written by Sharon Webb and published by Springer. This book was released on 1997-07-17 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the experimental determination of the physical properties of silicate melts and magmas close to glass transition. Abundant new data are presented. The same type of measurement is performed on a range of melts to test the effect of composition on physical properties; and a range of different techniques are used to determine the same physical properties to illustrate the relationships between the relaxation of the melt structure and the relaxation of its physical properties. This book is of interest to experimental researchers in the discussion of data obtained from both a materials science and a geoscientific point of view.

Book Synopsis Performance of Cement-Based Materials in Aggressive Aqueous Environments by : Mark Alexander
Download or read book Performance of Cement-Based Materials in Aggressive Aqueous Environments written by Mark Alexander and published by Springer Science & Business Media. This book was released on 2012-12-18 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe – adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.

This book was released on 2003-03-27 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting a unified approach, this book focusses on the concepts and theoretical methods that are necessary for an understanding of the physics and chemistry of the fluid state. The authors do not attempt to cover the whole field in an encyclopedic manner. Instead, important ideas are presented in a concise and rigorous style, and illustrated with examples from both simple molecular liquids and more complex soft condensed matter systems such as polymers, colloids, and liquid crystals.
Book Synopsis Advances in Turbulence VII by : Uriel Frisch
Download or read book Advances in Turbulence VII written by Uriel Frisch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Turbulence VII contains an overview of the state of turbulence research with some bias towards work done in Europe. It represents an almost complete collection of the invited and contributed papers delivered at the Seventh European Turbulence Conference, sponsored by EUROMECH and ERCOFTAC and organized by the Observatoire de la Côte d'Azur. New high-Reynolds number experiments combined with new techniques of imaging, non-intrusive probing, processing and simulation provide high-quality data which put significant constraints on possible theories. For the first time, it has been shown, for a class of passive scalar problems, why dimensional analysis sometimes gives the wrong answers and how anomalous intermittency corrections can be calculated from first principles. The volume is thus geared towards specialists in the area of flow turbulence who could not attend the conference as well as anybody interested in this rapidly moving field.
