Silica translucent aerogels are unique materials able to improve the thermal insulation performance of buildings without compromising daylight transmission. The aim of the book is to give a general overview on state of the art research on translucent aerogels and their applications in buildings and to provide a data set about thermal and physical properties, useful in buildings' energy performance simulation and design.Silica aerogels are nanostructured solid materials made of approximately 96% air and 4% silica. They show a thermal conductivity in the 0.012-0.020 W/mK range and excellent optical properties, especially visible transmission. They come in granular and monolithic form. Granular aerogels are relatively easy to produce and less expensive than monolithic panes, but show worse optical and thermal performance. Monolithic aerogels enable vision through the material, but their fabrication process is not developed at an industrial scale.The book collects the contributions of experts in the field of translucent aerogels from all over the world. The contents of the eight chapters are detailed as follows:Chapter 1 is the contribution from Union College, Schenectady (USA). The chapter reviews the chemical approaches to silica wet gels preparation, the drying methods used to yield monoliths, and the challenges and limitations associated with its production.Chapter 2 is a contribution from EMPA, Dübendorf (Switzerland). It is a review of current state of the art research on silica aerogel granulate production, including raw materials selection, hydrophobization strategies, and drying methodologies. Chapter 3 is a contribution from Takenaka Corporation, Tokyo (Japan). The main techniques for the optical properties evaluation are described and data are provided. An original application of translucent aerogels in buildings and future research topics are also proposed.Chapter 4 is a contribution from Recep Tayyip Erdogan University, Rize and Ataturk University, Erzurum (Turkey). A review of the thermal properties of aerogels is provided, highlighting their better performance when compared to conventional and superinsulation materials.Chapter 5 is a contribution from the University of Perugia, Perugia (Italy). The acoustic properties of both granular and monolithic systems are investigated. For example, the influence of granule size and layer thickness that is deepened for granular aerogels is discussed, while for the monolithic form, the little data that is currently available is reported on. Chapter 6 is a contribution from the University of Tuscia, Viterbo (Italy) and Buro Happold Ltd, London (UK). It is focused on Life Cycle Assessment of silica aerogel, showing the research challenges in understanding its environmental impact, lower than the one of conventional thermal insulating glazing systems.Chapter 7 is a contribution from the University of Lyon and INSA-Lyon, Lyon (France). An overview of measurement methods and modeling tools available in literature is provided and a summary of the main mechanical properties of both monolithic and granular aerogels is reported on.Chapter 8 is a contribution from the Norwegian University of Science and Technology, Trondheim and SINTEF, Trondheim (Norway). Authors present their experimental investigations on various aerogel systems in different building envelopes (new aerogel glass material, aerogel-incorporated concrete, and so forth).

Surfactants and Interfacial Phenomena Milton J. Rosen Bridging the gap between purely theoretical aspects of surface chemistry and the purely empirical experience of the industrial technologist, this book applies theoretical surface chemistry to understanding the action of surfactants in modifying interfacial phenomena. It surveys the structural types of commercially available surfactants and discusses interfacial phenomena, the physicochemical principles underlying the action of surfactants in each phenomenon, and the effect of structural changes in the surfactants and environmental changes on their action. Tables of data on various interfacial properties of surfactants, compiled and calculated from the latest scientific literature, are included. 1978 304 pp. An Introduction to Clay Colloid Chemistry, 2nd Ed. H. van Olphen This book provides valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems. Updated and enlarged, this edition includes new information on surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction--the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution. 1977 318 pp. Physicochemical Processes for Water Quality Control Walter J. Weber, Jr. Focusing on physicochemical rather than biological processes, this book presents a comprehensive treatise on the treatment of municipal and industrial water and wastewater. All of the physicochemical processes important to municipal and industrial water and wastewater treatment--coagulation, filtration, membrane processes, chemical oxidation, and others--are included and each is covered thoroughly from principle through application. To maintain a high level of expertise, contributions have been incorporated from specialists actively involved in research or engineering applications in each area considered. 1972 640 pp.

Small scale experiments using silica gel, ammonium nitrate and urea show that formation of guanidine nitrate becomes erratic if insolubles build up on the catalyst surface. The rate of production of insolubles increases rapidly with temperature, so that a trade-off between low conversions at lower temperatures and insoluble formation at higher temperatures is possible. The yield/temperature relationship is a property of the silica gel used. Yields of guanidine nitrate can be higher than predicted, possibly because by-product water is removed in the form of ammonium silicates rather than ammonium carbamate. Experiments with N15 and 018 suggest that guanidine nitrate does not result from the direct combination of cyanamide and urea: oxygen (or hydroxyl groups) of the silica gel plays an important role. The rate of formation of guanidine nitrate is second order (first order in both urea and ammonium nitrate). The phase diagram for the ternary system has been investigated.

This is the first book to address the hot topic of functional silica gels and their applications. Originally used mainly in chromatography, specialized silica gels have evolved into crucially important functional nanomaterials suitable for use in, amongst other things, chemical synthesis, analysis, purification, surface protection and drug release. It is estimated that the world's current 1 billion dollar market for sol-gels (mostly silica-based) will grow by more than 5% per year from 2006 to 2011. Actually, as many revolutionary products are now reaching the market, it will increase much faster. Commercial applications include glasses, paints, catalysts and fragrances. Medical uses include the delivery of vitamins, hormones and acne treatments and the synthesis of the powerful anticancer drug, taxol. Sol-gel technology also forms the basis of the MetaChip, thanks to which potential new drugs can be identified rapidly and simultaneously. With content relevant to both scientific and commercial viewpoints, the book will interest researchers and undergraduates as well as managers and consultants in the chemical industry. Those from an industrial background will gain a clear picture of what this technology is all about and how it can be used to solve their specific problems. All readers will benefit from the clear, concise style and consistent treatment of topics. The book demonstrates how chemists synthesize, from the bottom-up, tailor-made (nano)materials of immense practical importance spanning the fields of chemistry, physics, materials science, engineering, biology and medicine. It also shows how the versatility of silica gels results from their physical and chemical properties. An updated outlook on new commercial products, and the companies which make them, greatly adds relevance and practical value to the text.

This book explores the improvement in thermal insulation properties of protein-based silica aerogel composites fabricated by a novel, inexpensive and feasible method. The resulting material exhibits polymeric foam behavior including high compressibility, super-hydrophobic qualities and excellent strain recovery in addition to low thermal conductivity. The fabrication methodologies are explained in great detail and represented in flowcharts for easy reference and understanding. This monograph gives readers a new perspective on composite fabrication using methods other than the traditional ones and explores the endless ways of altering the composition to modify the properties of the silica aerogel composites. Applications for this novel composite are diverse and range from those in the pharmaceutical and aerospace industries to the oil and gas industries.

Each of the many different varieties of silica is characterised by its crystalline or amorphous structure and its specific physico-chemical surface properties. It is these surface characteristics which determine the applications of the silica, be it for chromatography, dehydration, polymer reinforcement or other processes. All the recent advances in the use of established and more modern methods for the determination of the surface and morphological characteristics of silicas, are found in this book written by a team of European experts. Analytical methods discussed include: solid state nuclear magnetic resonance, infra-red spectroscopy and adsorption methods. Emphasis is given to the nature and distribution of hydroxyl groups on silica surfaces; the final chapter gives a general survey of the health and safety aspects of silica.
