Описание: 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 0.012a0.020 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, DA"bendorf (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).

Advances in Aerogel Composites for Environmental Remediation presents both contextual information about aerogels and details about their application in environmental remediation. A wide variety of aerogels are discussed, ranging from common to advanced and from natural to synthetic. By exploring ongoing research and developments in the environmental remediation technologies using aerogel and its composites, this book addresses common day-to-day environmental problems and presents solutions to the use of aerogel materials. The chapters discuss fabrication of various aerogel composites, along with their design and applications toward different environmental remediation technologies. Additionally, the properties and advantages of aerogels are compared and contrasted to those of traditional materials.
Given the consistent increase in environmental pollution, there is an urgent need to explore new materials for advances in remediation technology. Advances in Aerogel Composites for Environmental Remediation brings researchers and practitioners in the fields of environmental remediation, environmental science, and engineering to the forefront of remediation technologies with a thorough breakdown of the benefits of and techniques relevant to aerogel composites.
Covers basic properties, unique properties, and fabrication techniques of aerogels, from basic silica aerogels to present-day conventional aerogels
Discusses most of the major environmental remediation techniques and the advantages of using aerogels for these remediation techniques in comparison to using traditional methods
Presents future prospects for utilizing aerogels in modern day-to-day life and in the fabrication of tangible new products

Описание: Demonstrates how the properties of cured epoxy resins are improved significantly by the addition of surface-modified silica nanoparticles. Addition of nanosilica typically linearly increases both the modulus and the fracture toughness, and compressive strength and fatigue performance can be improved significantly as well.

Описание: The title of this book describes the two extremes of ceramic invention from aesthetically beautiful and decorative works of art that graced the tables of the aristocracy to the functional silica brick that lined the smelting furnaces of industrialised nations in the 19th century designed to produce iron, copper and glass. Both of these ceramics are linked to one man, William Weston Young (1776-1847) and with his contemporaries both of these ceramic extremes became world leaders in their own right. The book traces the history of Young and his ambitions, his interactions with numerous associates and the influence these ceramics attained in 19th century society. The book provides a sequel to the two preceding texts on Nantgarw and Swansea porcelains (also published by Springer), which cover one extreme and extends the discourse onto the other extreme, which until now has been relatively ignored despite its scientific and engineering importance. The trilogy has now therefore been completed. This book examines the historical documentation along with scientific analytical data from the last 100 years up to the present in a novel holistic forensic approach.It will be of interest to porcelain collectors, ceramics analysts, museum ceramic curators, ceramic historians, analytical scientists, cultural heritage preservation, industrial archaeologists and industrial museums.
