Les Nanomat Riaux Et Leurs Applications Pour L Nergie Lectrique

Les nanotechnologies apportent un fort potentiel d’innovation et de rupture dans de nombreux domaines. Leurs applications pour l’énergie en est un champ important, car la synthèse et la structuration des nanomatériaux y ouvrent des voies de progrès notables. Si divers ouvrages décrivent les innovations promises par les nanotechnologies sur des thématiques scientifiques générales ou spécialisées, très peu abordent le chemin qui va des nouvelles propriétés aux applications pour l’énergie électrique et ses usages. Cet ouvrage présente, sur des bases scientifiques solides, les apports des nanotechnologies et plus particulièrement des nanomatériaux aux enjeux de la production d’électricité et de ses usages. Après un panorama des effets physiques qui peuvent être exploités à ces échelles pour améliorer les propriétés des matériaux ou leur fonctionnalité, leur application à la production d’électricité, à son stockage, à ses usages ainsi qu’au traitement de questions environnementales est abordée. Elle conduit à explorer les domaines de l’électrochimie, du photovoltaïque, de la thermoélectricité, des propriétés mécaniques et thermiques des matériaux ou encore des membranes et des surfaces ultrahydrophobes. Chaque chapitre constitue une monographie exhaustive enrichie d’une abondante iconographie et d’une bibliographie très complète. Les meilleurs experts de chaque domaine ont été réunis, faisant de cet ouvrage une référence incontournable. Au confluent de plusieurs disciplines et en prise directe sur un vaste champ d’applications, ce livre s’adresse à un large public : ingénieurs et chercheurs, étudiants des écoles d’ingénieurs ou des universités aux niveaux licence et master.

Encapsulations, a volume in the Nanotechnology in the Agri-Food Industry series,presents key elements in establishing food quality through the improvement of food flavor and aroma. The major benefits of nanoencapsulation for food ingredients include improvement in bioavailability of flavor and aroma ingredients, improvement in solubility of poor water-soluble ingredients, higher ingredient retention during production process, higher activity levels of encapsulated ingredients, improved shelf life, and controlled release of flavor and aroma. This volume discusses main nanoencapsulation processes such as spray drying, melt injection, extrusion, coacervation, and emulsification. The materials used in nanoencapsulation include lipids, proteins, carbohydrates, cellulose, gums, and food grade polymers. Applications and benefits of nanoencapsulation such as controlled release, protections, and taste masking will be explained in detail. Includes the most up-to-date information on nanoencapsulation and nanocontainer-based delivery of antimicrobials Presents nanomaterials for innovation based on scientific advancements in the field Provides control release strategies to enhance bioactivity, including methods and techniques for research and innovation Provides useful tools to improve the delivery of bioactive molecules and living cells into foods

Wood adhesives are of tremendous industrial importance, as more than two-thirds of wood products in the world today are completely or partially bonded together using a variety of adhesives. Adhesive bonding offers many advantages over other joining methods for wood components, and there has been a great deal of R& D activity in devising new wood adhesives or improving the existing ones. The modern mantra in all industrial sectors is: "think green, go green," which has attracted much attention in the wood adhesive industry. Therefore, there is also a lot of research activity in synthesizing environmentally benign and human-friendly wood adhesives. This book is divided into four parts: Part 1: Fundamental Adhesion Aspects in Wood Bonding; Part 2: Synthetic Adhesives; Part 3: Environment-friendly adhesives; and Part 4: Wood Welding and General Paper. It addresses many different types of wood adhesives, as well as bonding (welding) of wood components without adhesives, a more recent development. The information contained in this book is valuable for individuals engaged in all aspects of wood adhesion and adhesives and, hopefully, will inspire new ideas in wood adhesives, a topic of vital industrial importance.
