This study investigates CO 2 capture on in house prepared Li 4 SiO 4 , a commercial Li 4 SiO 4 and a commercial derived CaO under the same experimental conditions in order to compare their performance, with emphasis on the in house prepared Li 4 SiO 4 . The selected commercial Li 4 SiO 4 resulted unsuitable for CO 2 absorption emission due to the insignificant CO 2 uptake after regeneration. The commercial derived CaO absorbs 41 wt.%, which was the highest CO 2 uptake among the studied samples. However, this sample underwent a severe decay after 12 carbonation regeneration cycles, despite the mild regeneration conditions used (700 ºC under N 2 ), reaching an almost constant CO 2 uptake value (10 wt.% after 18 cycles). The in house prepared Li 4 SiO 4 absorbs 30 wt.%, which was near the theoretical CO 2 uptake for Li 4 SiO 4 . After an initial loss of CO 2 uptake from near 30% to 26 %, the performance of in house prepared Li 4 SiO 4 was maintained after 16 cycles, under the same conditions that those used for CaO. The effect of CO 2 concentration on CO 2 uptake was to obtain the inversion temperature for practical CO 2 concentrations. Due to the significant differences amongst inversion temperatures from different equilibrium plots, experimental inversion temperatures were obtained by Temperature Programmed technique for absorption under a CO 2 concentration of 4% and for emission under a CO 2 concentration of 70%, giving 525 ºC and 660 ºC, respectively. A cyclic test was conducted with in house prepared Li 4 SiO 4 : absorption at 520 ºC under a CO 2 concentration of 4% and regeneration at 675 ºC under a CO 2 concentration of 70%. Under these mild thermal conditions the sample did not exhibit a CO 2 uptake decay, indicating that this sorbent could be efficiently used for high temperature CO 2 capture from power plant flue gas. Keywords: Li 4 SiO 4 ; sorbent; CO 2 capture; regeneration; cycles; thermodynamics; temperature programmed technique.

puso en marcha en ocho colegios de esta Comunidad Autónoma, de manera experimental, el programa "Explora" para la atención al alumnado de capacidad intelectual elevada. Se planearon tanto talleres presenciales como online. La implementación de los presenciales (objetivos, contenidos, actividades, selección de alumnado, sesiones, etc.) fue diseñada por los propios centros docentes, estructurándose su funcionamiento de manera tradicional. Sin embargo, los cuatro talleres online (matemáticas, lenguaje, informática e inteligencia emocional) se desarrollaron siguiendo el enfoque deportivo (Sports Approach) de Joan Freeman. En el presente artículo se muestra la fundamentación, desarrollo y evaluación de estos talleres online. Se realizó una evaluación cualitativa y cuantitativa cuyos resultados son muy alentadores: se confirmó la buena aceptación del programa por parte de los participantes y se comprobó su adecuación para la selección del alumnado de elevada capacidad.
