Caracterización in-situ de las propiedades espectrales de absorción de los aerosoles atmosféricos en Valencia

2015

Según el último informe del Panel Intergubernamental sobre Cambio Climático (IPCC, 2013) cada una de las tres últimas décadas ha sido más cálida que la anterior a nivel de superficie y, en conjunto, más cálidas que ninguna de las precedentes desde 1850. En la atmósfera, las causas de este aumento de temperatura están relacionadas directamente con la presencia de gases de efecto invernadero y también de aerosoles. En la última década, el estudio de los aerosoles atmosféricos ha cobrado gran interés debido al papel que estos desempeñan en el clima a través del forzamiento radiativo, siendo su interacción mayor que la de algunos gases de efecto invernadero de vida corta (p.e., CO o NOx) Mientr…

Formation and growth of palladium nanoparticles inside porous poly(4-vinyl-pyridine) monitored by operando techniques: The role of different reducing…

2017

In this work we followed the formation of palladium nanoparticles, starting from palladium (II) acetate precursor, inside a poly(4-vinylpyridine-co-divinylbenzene) polymer in presence of different reducing agents. The formation and growth of palladium nanoparticles in presence of H-2 was followed as a function of temperature by simultaneous XANES-SAXS techniques, coupled with DRIFT spectroscopy in operando conditions. It was found that the pyridyl functional groups in the polymer plays a fundamental role in the stabilization of the palladium (II) acetate precursor, as well as in the stabilization of the palladium nanoparticles. The effect of a thermal treatment in alcohol (ethanol and 2-pro…

De l’avoir lieu à l’être-lieu : parcours dans l’œuvre de Dorothy Cross

2019

Les installations et performances de Dorothy Cross, artiste contemporaine irlandaise, reposent sur un profond respect de la nature et visent à remettre en cause, de manière poétique, l’anthropocentrisme des sociétés occidentales. En mettant en scène le surgissement inattendu d’une bestialité archaïque symbolisée par le requin, la méduse ou les serpents, animaux sauvages mais culturellement marqués, et en s’immergeant dans des milieux et biotopes sauvages, l’artiste opère des renversements spatiaux : l’espace culturel devient un espace ensauvagé. Les procédés d’inscription, d’incrustation ou de projection de motifs évoquant une nature non domestiquée opèrent une symbiose entre l’homme et l’é…
