This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le développement de procédés catalytiques pour la valorisation chimique du dioxyde de carbone (CO2), suscite un intérêt grandissant en termes de chimie du carbone et de développement durable. Les travaux de cette thèse portent sur l'étude de la synthèse de carbonates cycliques à partir du couplage du CO2 avec des époxydes. De nombreux catalyseurs ont été développés dont les sels d'ammoniums fournissant le nucléophile nécessaire pour initier la réaction par ouverture de l'époxyde. Notre projet propose une nouvelle approche qui consiste à augmenter la nucléophilicité du catalyseur via une chimie hôte-invité dans laquelle des récepteurs moléculaires de type cavitands viennent sélectivement encapsuler les cations ammoniums, libérant ainsi l'anion nucléophile pour une meilleure réactivité. Notre système catalytique, testé à 1 bar de CO2, a notamment démontré tout son potentiel par l'activation accrue de sels de tétraméthylammonium initialement inactifs. Des expériences effectuées sous une pression de CO2 de 10 bar, ont permis d'étudier l'influence de la structure des cavitands et de montrer qu'une double activation était possible grâce à la conception de cavitands comportant des fonctions acides de Brönsted et des propriétés d'encapsulation optimales. Une application à la catalyse hétérogène a finalement été initiée par l'immobilisation des ammoniums ou des cavitands sur des supports à base de silice pour profiter des avantages de tels procédés.
Book Synopsis Valorisation des Dérivés Carboniques par hydrogénation by : Sebastien Coufourier
Download or read book Valorisation des Dérivés Carboniques par hydrogénation written by Sebastien Coufourier and published by . This book was released on 2018 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'utilisation de dioxyde de carbone comme source de carbone C1 pour produire des plateformes chimiques ou comme source de carburant est une alternative à la pétrochimie et pourrait permettre son recyclage. Actuellement, les principaux procédés décrits pour la valorisation du CO2 font appel à des réducteurs en quantités stoechiométriques (ce qui génère des déchets), des métaux nobles (disponibilité limitée, toxicité et coût élevé). Dans cette course environnementale et économique, une des réponses, mais aussi un des challenges de la chimie moderne, est la préparation de nouveaux complexes organométalliques de fer et leur utilisation en catalyse. Basé sur notre expertise dans le domaine de la synthèse, de la catalyse et du développement de complexes organométalliques, ce projet propose de développer de nouvelles méthodologies rapides, efficaces, sélectives et éco-compatibles pour la réduction du dioxyde de carbone et des carbonates par hydrogénation avec des complexes bifonctionnels de fer.

Book Synopsis Cities, Regions and Flows by : Peter V. Hall
Download or read book Cities, Regions and Flows written by Peter V. Hall and published by Routledge. This book was released on 2013 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities, Regions and Flows presents a theoretical framework for understanding the changing relationship between places and physical movement, and thoughtfully prepared case studies from five continents on how cities relate to value chains, and how they ensure accessibility and urban liveability in an increasingly contested policy environment. Moreover, the book discusses how urban policies attempt to solve related conflicts in terms of infrastructure provision, land use, local labour markets and environmental sustainability. The two subsystems that are of major interest here - urban regions on the one hand, and logistics management and physical distribution on the other - develop in quite distinct, and often contradictory, ways. Whereas urban regions face disintegration due to the expansion of the built environment and the spatio-temporal fragmentation of life-worlds and regional systems, the logistics system itself demands integration in order to keep flows moving and to reduce costs. Physical flows, networks and chains thus have a fundamental impact on urban restructuring.
Book Synopsis Cambridge Handbook of Engineering Education Research by : Aditya Johri
Download or read book Cambridge Handbook of Engineering Education Research written by Aditya Johri and published by Cambridge University Press. This book was released on 2014-02-10 with total page 1124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Book excerpt: This report reviews engineering's importance to human, economic, social and cultural development and in addressing the UN Millennium Development Goals. Engineering tends to be viewed as a national issue, but engineering knowledge, companies, conferences and journals, all demonstrate that it is as international as science. The report reviews the role of engineering in development, and covers issues including poverty reduction, sustainable development, climate change mitigation and adaptation. It presents the various fields of engineering around the world and is intended to identify issues and challenges facing engineering, promote better understanding of engineering and its role, and highlight ways of making engineering more attractive to young people, especially women.--Publisher's description.
Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Book Synopsis Biowarfare in America by : Jim Keith
Download or read book Biowarfare in America written by Jim Keith and published by Illuminet Press. This book was released on 1999 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The era of chemical and biological megadeath is upon us, and the potential of deadly biowarfare attacks from governments, militant independent groups, and even individuals is far greater than it has been at any time in the past. At this time, more than twenty-five countries are developing, or have stockpiles of chemical and biological weapons, in many cases in sufficient quantities to wipe out the entire population of the world. So far the danger of chemical and biological aggression has been little acknowledged, and, at least in America, little prepared for by federal and local government. Most terrorist threats and attacks are not widely reported in the mainstream media. Although information about the proliferation of man-made diseases is carefully suppressed by governments and the media they will be covered in the pages of this book. Not only is America unprepared and ignorant of what is happening, but the people in government and scientific professions who do know, who should be warning the American public about the dangers of chemical and biological terrorism, are instead doing their utmost to hide this information from us; information that is vital for our survival.The information that is contained in the pages of this book will not be measured or calculated to reassure people that everything is fine, when reassurance is the exact opposite of what is needed at this time. It may even give you nightmares when you realise the real circumstance that we are in. The information in the pages that follow will be the truth about the biowarfare threat to America.
