“…If not well hydrophobised, contact with water could demolish an aerogel structure because of the surface tension in the pores [33]. In this case, aerogel is often used in combination with a vacuum, where the envelope prevents water inclusion and the vacuum reduces the thermal conductivity furthermore.…”

Aerogels are regarded as one of the most promising high performance thermal insulation materials for building applications today. With a thermal conductivity down to 13 mW/(mK) for commercial products they show remarkable characteristics compared to traditional thermal insulation materials. Also the possibility of high transmittances in the solar spectrum is of high interest for the construction sector. With the proper knowledge they give both the architect and engineer the opportunity of re-inventing architectural solutions. Within this work, a review is given on the knowledge of aerogel insulation in general and for building applications in particular.

“…The optical transmission and the scattering properties of silica aerogels are widely investigated in the literature (Baetens et al 2011;Jensen et al 2004;Reim et al 2004Reim et al , 2005Buratti 2003Buratti , 2004Buratti andMoretti 2011, b, 2012, b). The attitude to diffuse natural light indoors is described by the light transmittance (s v ), very important since the natural light concurs to save electric energy in daytime and affects general health of human beings.…”

This chapter deals with the application of highly energy-efficient windows and skylights with silica nanogel as a strategy in the building refurbishment. Aerogel windows seem to have the largest potential for improving the thermal performance and daylight in fenestration industry, because of very low conductivity, density, and a good optical transparency. A state-of-the-art review of nanogel windows in building applications is firstly presented. Then, the proprieties of nanogel glazings in terms of thermal, lighting, and acoustic insulation solutions are discussed. Finally, the potential of the nanogel windows for energy saving in order to achieve a nearly zero-energy building is described, thanks to the results of a case study.

“…Des applications avec de l'argon comme gaz isolant thermique ou acoustique dans les fenêtres à double vitrage existent déjà [10,11]. De même, l'argon est utilisé comme gaz isolant dans les combinaisons étanches de plongée, surtout dans le cas de plongées techniques ou extrêmes [12].…”

L’argon : utilisations, toxicité et stratégie analytique en toxicologie médicolégale

Résumé -Bien qu'intrinsèquement non toxiques, les gaz nobles comme l'argon entraînent à fortes concentrations une déplétion d'oxygène pouvant mener jusqu'à l'asphyxie. Si l'argon se retrouve dans la circulation générale, celui-ci peut même être responsable d'embolies parfois fatales. Cependant, les propriétés d'inerties physicochimiques de ce gaz le rendent très utile dans de nombreuses applications actuelles. Ces applications étant en constante augmentation, il n'est pas rare d'observer proportionnellement des intoxications parfois létales liées à ce gaz. Ainsi, devant le manque d'harmonisation des prélèvements d'échantillons biologiques afin de mettre en évidence de telles intoxications aux gaz nobles et devant l'augmentation du nombre de cas, il devient nécessaire d'établir un état des lieux sur l'utilisation de l'argon, sa toxicité et la stratégie analytique à adopter dans le contexte médico-légal. Mots clés :Argon, gaz noble, échantillonnage de gaz, analyse de gaz Abstract -Even though noble gases such as argon are intrisically non-toxic, they will enhance an oxygen-depletion at high concentrations. This depletion may lead to asphyxia. If argon is found in blood flow, it could be responsible of an embolism. However, its inert physicochemical properties appear to be very useful to a wide range of current applications. The rise of these applications induces a proportionnal increase of lethal intoxications due to this gas. Thus, as no standardization of biological samples exists, and knowing the increase of argon intoxication cases, it seems necessary to establish an incoming inventory of fixture concerning the use of argon. It will confirm its toxicity properties and will highlight other intoxications due to noble gas. This should lead to a new analytical strategy suitable to the forensic context.
