Water is one of the main concerns of modern societies. Climate change will significantly complicate access to quality water for millions of people worldwide and the threat of contamination of aquatic resources by poor wastewater management is real and growing fast. Therefore, there is an urgent need to develop efficient and sustainable wastewater treatment methods. Although there are numerous water treatment methods, not all of them are equally sustainable, be it environmentally, economically or ethically. For this book, some of the latest advances in sustainable wastewater treatments were collected and 13 articles selected. The selected articles deal with aspects such as the removal of nanoparticles, the applicability of constructed wetlands, the recovery/removal of wastewater, the use of low-cost bio-sorbents, the optimization of activated sludge, the application of advanced oxidation technologies, and the modeling of reverse osmosis systems. This book will give the reader an idea of the latest trends in the sector of sustainable wastewater treatment.
This book examines nonlinear optical effects in nonlinear nanophotonics, plasmonics, and novel materials for nonlinear optics. It discusses different types of plasmonic excitations such as volume plasmons, localized surface plasmons, and surface plasmon polaritons. It also examines the specific features of nonlinear optical phenomena in plasmonic nanostructures and metamaterials. Chapters cover such topics as applications of nanophotonics, novel materials for nonlinear optics based on nanoparticles, polymers, and photonic glasses.
This book offers an overview of the recent studies and advances in environmental catalysis by nanomaterials, considering both the fundamental and the technological aspects. It offers contributions in different areas of environmental catalysis, including the catalytic and photocatalytic abatement of environmentally hazardous effluents from stationary or mobile sources, the valorization of waste and the production of sustainable energy. In other words, this monograph provides an overview of modern environmental and energy related applications with a particular emphasis to nano-sized catalytic materials. Recent concepts, experimental data and advanced theories are reported in this book to give evidence of the environmental and sustainable applications that can be found in the highly interdisciplinary field of catalysis.
This book contains contributions to the Symposium of the Italian Macromolecules Science and Technology Association (AIM). This conference, which takes place every two years in various Italian cities, represents the most important gathering for the AIM members. The 17th AIM Symposium held in Naples in 2005 celebrated the 30th AIM anniversary. The symposium covered the following topics: Synthesis and modifications of polymers; structure, properties and macromolecular architecture; polymers for biomedical applications; functional polymers and polymers for special uses; biopolymers.
Dopo l'esplosione dello scandalo delle discariche in Campania e la sentenza d'appello del processo Spartacus, i Casalesi sono balzati alla ribalta della cronaca. Come nel caso dei Corleonesi in Sicilia, il clan più potente e sanguinario della camorra non viene dalla città ma dalla campagna: il paese di Casal di Principe, in provincia di Caserta. E proprio un'alleanza organica con la mafia è all'origine del trionfo dei Casalesi, che incarnano lo spirito e i riti della vecchia camorra e insieme dimostrano una straordinaria capacità di adattarsi al presente. Fin dagli anni Ottanta hanno sviluppato un controllo paramilitare del territorio, esigono percentuali sulla vendita di droga, sulla pr...
