Download or read book Translucent Silica Aerogel written by Cinzia Buratti and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers presented at the "First International Sympo st sium on Aerogels (1 ISA)", held in September 1985 at. the University of Wiirzburg, Fed. Rep. of Germany. It was the first meet.ing of this kind, wit.h participants from several European count.ries, the United States of America, Canada, South America, and Africa. The meeting was interdisciplinary, with most of the participants being physicists, chemists or material scientists ei ther from universities or from industrial research institutes. Let me try to shed some light upon the class of substances the symposium was about: Aerogels are extremely porous high-tech materials, consisting ei ther of silica, alumina, zirconia, stannic or tungsten oxide or mixtures of these oxides. Due to their high porosity (up t.o 99%!) and t.heir large inner surface, aerogels serve as especially active catalysts or as catalytic subst.rates, as adsorbents, fillers, reinforcement agents, pigments and gellifying agents. Silica aerogels as translucent or transparent superinsulating fillers in window systems could help to considerably reduce thermal losses in windows and to improve the energy balance in passive solar systems. Aerogels also have fas cinating acoustic properties - the sound velocity can be as low as 100 m/s! The production of aerogels starts with the controlled conversion of a sol into a gel: The growth of clusters or polymer chains from a chemical solution, the cross-linking of these primary entities and the formation of a coherent network - still embedded in a liquid.

Download or read book CO2 microemulsions with additives written by Yvonne Pütz and published by Cuvillier Verlag. This book was released on 2015-07-20 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improved building insulation is an important part of today´s efforts on energy saving. Here, nano-insulation materials promise especially low thermal conductivity. Therefore, an easy and cost-efficient production of these materials is an aim of present material research. One approach towards these materials is the expansion and fixation of polymerisable microemulsions of supercritical blowing agents. However, the nano-sized bubbles are found to undergo undesired coarsening processes. In order to reduce the increasing interfacial tension emerging during expansion and therewith the coarsening it was suggested to add low-molecular hydrophobic substances to the supercritical microemulsion. And indeed, the addition of cyclohexane to a microemulsion of the type brine – CO2 – fluorinated surfactants was found to reduce the fluorinated surfactant content – a measure for the interfacial tension - considerably. In this work a systematic small-angle neutron scattering (SANS) contrast variation was performed and the data were analysed by model-independent Fourier analysis. It was found that a concentration gradient of cyclohexane inside the CO2/cyclohexane microemulsion droplets forms. Interestingly, the analysis reveals a depletion zone close to the amphiphilic film which presumably develops due to the known repulsive interactions of cyclohexane and the fluorinated surfactant tails. Using a specially designed high pressure SANS cell to perform stroboscopic pressure jumps, the influence of cyclohexane on pressure-induced elongation of microemulsion droplets as well as the early state of foaming after expansion was studied. Here, the pressure-dependent thermodynamic stability of such microemulsions allows for a fast repeatability of the pressure cycles. It turned out that cyclohexane systematically slows down the structural changes in all processes. Parallel pressure jump experiments with poly-(N-isopropylacrylamide) (PNIPAM) particles revealed that hydration and dehydration kinetics can be studied with the same experimental setup. The first kinetic experiments which combine a CO2-microemulsion mixed with PNIPAM particles indicate that PNIPAM acts as a stabiliser for the microemulsion and further reduces the thermodynamic driving force of the demixing process.
