Climate warming has substantially advanced spring leaf flushing, but winter chilling and photoperiod co-determine the leaf flushing process in ways that vary among species. As a result, the interspecific differences in spring phenology (IDSP) are expected to change with climate warming, which may, in turn, induce negative or positive ecological consequences. [...]

21 p, 583.2 KB Oxygen Reduction Mechanisms in Nanostructured La0.8Sr0.2MnO3 Cathodes for Solid Oxide Fuel Cells / Sacanell, Joaquín (CONICET) ; Hernández Sánchez, Joaquín (Comisión Nacional de Energía Atómica) ; Rubio López, Adrián Ezequiel (Comisión Nacional de Energía Atómica) ; Martinelli, Hernán (Comisión Nacional de Energía Atómica) ; Siepe, Jimena (Comisión Nacional de Energía Atómica) ; Leyva, Ana Gabriela (Universidad Nacional de General San Martín) ; Ferrari, Valeria Paola (CONICET) ; Juan, Dilson (CONICET) ; Pruneda, Miguel (Institut Català de Nanociència i Nanotecnologia) ; Mejía Gómez, Augusto (CONICET) ; Lamas, Diego Germán (Universidad Nacional de General San Martín)
In this work we outline the mechanisms contributing to the oxygen reduction reaction in nanostructured cathodes of LaSrMnO (LSM) for Solid Oxide Fuel Cells (SOFC). These cathodes, developed from LSM nanostructured tubes, can be used at lower temperatures compared to microstructured ones, and this is a crucial fact to avoid the degradation of the fuel cell components.

12 p, 1.0 MB One-Pot Synthesis of Cationic Gold Nanoparticles by Differential Reduction / Sperling, Ralph A. (Institut Català de Nanociència i Nanotecnologia) ; García Fernández, Lorena (Institut Català de Nanociència i Nanotecnologia) ; Ojea-Jiménez, Isaac (Institut Català de Nanociència i Nanotecnologia) ; Piella, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Gómez Bastús, Neus (Institut Català de Nanociència i Nanotecnologia) ; Puntes, Víctor (Institut Català de Nanociència i Nanotecnologia)
The size-controlled synthesis of cationic particles by differential reduction of HAuCl precursor in the presence of NaBH and 1-aminoundecane-12-thiol (AUT) is reported. The number of seed particles is determined by the fraction of the initially Au precursor reduced by NaBH present in the reaction mixture, which are then grown larger by the AUT, acting as both weak reducing agent and stabilizing surfactant.

LaSrMnO (LSM) is one of the most commonly used cathodes in Solid Oxide Fuel Cells (SOFC). In spite of the fact that nanostructured cathodes are expected to display improved performance, the high operating temperature (∼ 1000°C) of LSM-based SOFCs hinders their stability. [...]

GeoBioTec - GeoBiociências) ; Rocha, Fernando (Universidade de Aveiro. GeoBioTec - GeoBiociências)
In cases where the provenance of raw materials used in the manufacture of local archeological ceramics is of interest, a detailed study of thermal transformations of minerals may be useful. The purpose of this study was to measure mineralogical transformations of different types of clays obtained during experimental firing runs, carried out at different temperatures, with the main goal of establishing Algarve reference groups based on the composition of raw material and high-temperature mineralogy, which may be compared with ceramics in studies of provenance.
