This book was released on 2010 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans une deuxième partie, j’aborde les possibilités offertes aujourd’hui d’associer un calcul des paramètres RMN sur les bases de la chimie quantique, à l’approche expérimentale. Je montre notamment la convergence des 2 approches par l’étude de l’oxygène-17 de phosphates cristallisés pour déduire des règles simples permettant de relier les paramètres quadripolaires à l’environnement local du noyau. Par la suite, l’étude d’un système vitreux simple démontre comment dynamique moléculaire et DFT permettent de vérifier un modèle étendu de distribution des paramètres quadripolaires, en lien direct avec la géométrie locale autour des oxygènes. Enfin, je finirai par exposer mes projets en insistant sur les relations à maintenir entre méthodologie et étude par RMN de systèmes réels. En particulier, je montrerai, à partir de résultats récents en catalyse hétérogène, comment l’ensemble des outils RMN ouvre de nouvelles voies d’exploration de la structure locale de systèmes greffés sur surface, notamment pour proposer des modèles de réactivité dans ces matériaux.
Book Synopsis Conservation Science for the Cultural Heritage by : Evangelia A. Varella
Download or read book Conservation Science for the Cultural Heritage written by Evangelia A. Varella and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Science is a rather innovative application of instrumental analysis with steadily increasing importance. Although the first attempts for preserving material from the cultural heritage on a scientific basis are found in the 19th century pioneer chemistry years, only the use of sophisticated physicochemical techniques results in effective identification and deterioration studies of monuments and objects, and in reliable intervention procedures. This volume allows to gain solid knowledge and improved skills on the ways separation schemes and diagnostic methodologies are applied in the safeguarding and authentication of tangible works of art; as well as on the modes of implementing novel safeguarding practices built on well-established principles – such as the use of laser in the decontamination of objects. All techniques are covered at a state-of-the-art level; while selected applications permit addressing major groups of materials and artefacts. Conservation Science is nowadays taught at master’s level in all developed countries, and museum laboratories increasingly adopt scientific approaches in their restoration initiatives. The book is intended as a valuable tool for students and professionals active in these frames. In addition, it provides an indispensable manual for participants in the specialized intensive courses, which are systematically offered by the authors under the auspices of the relevant European network.
