Outside the Bubble
Much time has been spent over the past decade debating whether social media contribute to democracy. Drawing on an original study of internet users across nine Western democracies, Outside the Bubble offers an unprecedented look at the effects of social media on democratic participation. This book argues that social media do indeed increase political participation in both online and face-to-face activities--and that they expand political equality across Western democracies. In fact, Cristian Vaccari and Augusto Valeriani find that, for the most part, social media do not constitute echo chambers or filter bubbles as most users see a mixture of political content they agree and disagree with. V...
Catalysis of Organic Reactions
Based on the papers and posters presented at the 16th Conference on Catalysis of Organic Reactions, this work offers advances in the study of catalysis as it relates to organic synthesis. The text highlights both theoretical and applied aspects of the field, and provides an historical overview of organic reaction mechanisms on metal surfaces.
Layered Double Hydroxides
Layered double hydroxides are one of the variety of names given to a family of layered materials first discovered in Sweden in 1842. These materials are interesting because their layer cations can be changed among a wide selection, and the interlayer anion can also be (nearly) freely chosen. Like cationic clays, they can be pillared and can exchange interlayer species -- thus increasing applications and making new routes to derivatives. The principle areas of application include catalyst support, anion scavengers, polymer stabilisers, and antacids. In the last several years, reviews and studies of LDHs have dealt with these uses. This book aims to update the current body of LDH knowledge from a wide array of views. The first section addresses the synthesis and physiochemical characterisation of these materials, and section two focuses on the applications of LDHs.
Structure-Activity and Selectivity Relationships in Heterogeneous Catalysis
Structure plays an important role in heterogeneous catalysis. It provides a framework for the arrangement and stragetic placement of key catalytic elements, hosting them in a prescribed manner so that their respective electronic properties can exhibit their desired catalytic functions and mutual interactions. Under reaction conditions these framework structures and their catalytic guests undergo dynamic processes becoming active participants of the overall catalytic process. They are not mere static geometric forms. The dynamics of catalytic structures are particularly vivid in selective oxidation catalysis where the lattice of a given catalytic solid partakes as a whole, not only its surfac...
Clay Surfaces
Clay plays an important role in everyday life. This versatile mineral is used in housing, improving the environment as a waste treatment material and also in biological applications and medical health care. Clay Surfaces contains 17 chapters which deal with various aspects of natural and man made (synthetic) clay. Well written by experts in both experimental and theoretical areas, this book takes the reader into the fascinating world of the chemistry and physics of clay mineral surfaces and interfaces as well as the complex phenomena on the surfaces involved in clay related systems. This book will provide a better understanding of the intervention mechanisms of interactions of soils in conta...
Natural Gas Conversion II
This Symposium provided the opportunity to review progress after more than 10 years of research and development in the field of natural gas conversion. Oxidative coupling of methane as a route to higher value fuels or feedstock was a major part of the program. The advances in understanding of reaction mechanisms and catalyst structure were discussed in a Plenary paper and in many of the contributed papers.The homogeneous gas phase chemistry involved in methane oxidation is relevant not only to oxidative coupling but also to synthesis gas and methanol production via partial oxidation. This field is reviewed in a Plenary paper and contributed papers describe developments in catalysts and techn...
Digital Politics in Western Democracies
A comparative analysis of political websites and their users from seven Western democracies. Digital politics is shorthand for how internet technologies have fueled the complex interactions between political actors and their constituents. Cristian Vaccari analyzes the presentation and consumption of online politics in seven advanced Western democracies—Australia, France, Germany, Italy, Spain, the United Kingdom, and the United States—from 2006 to 2010. His study not only refutes claims that the web creates homogenized American-style politics and political interaction but also empirically reveals how a nation’s unique constraints and opportunities create digital responses. Digital Poli...
Fashion at the Time of Fascism
The first visual history of Modernist Italian fashion during Benito Mussolini's Fascist regime, and the product of immense research, Fashion at the Time of Fascism charts the fashion industry's ambivalent negotiation of international couture and the bizarre dictates of Fascism, and the legacy of this era in shaping today's fashion industry. Authors Mario Lupano and Alessandra Vaccari explore and compare a huge range of forgotten archival sources, such as women's glossies, fashion, film and gossip magazines, photo archives, exhibition and commercial catalogues, books, manuals and magazines on tailoring, dressmaking, design and architecture, and corporate and government journals. This abundanc...
Scientific Bases for the Preparation of Heterogeneous Catalysts
It has become a tradition that every four years, the Université Catholique de Louvain and the Katholieke Universiteit Leuven jointly organize a symposium devoted to the scientific bases for the preparation of heterogeneous catalysts. These meetings bring together researchers from academia and industry and offer a forum for discussions on the chemistry involved in the preparation of industrial heterogeneous catalysts. This volume containing the Proceedings of the 8th International Symposium on Scientific Bases for the Preparation of Heterogeneous Catalysts consists of papers summarizing most of the 139 oral communications and posters selected by the international scientific committee, compos...
Natural Gas Conversion VII
This volume contains peer-reviewed manuscripts describing the scientific and technological advances presented at the 7th Natural gas Conversion Symposium held in Dalian, China, June 6-10, 2004, and a FREE CD-rom. This symposium continues the tradition of excellence and the status as the premier technical meeting in this area established by previous meetings.The manuscripts have been divided into eight different topics, Industrial Processes, Economics, Technology Demonstration and Commercial Activities;, Production of Hydrogen from Methane, Methanol, and Other Sources; Production of Synthesis; Fischer-Tropsch Synthesis of Hydrocarbons; From Synthesis Gas to; Catalytic Combustion; From Natural...
