(2018-06-28)Los materiales basados en molibdatos de lantano, con fórmula general La6-xMoO12-, son candidatos a membranas de separación de hidrógeno debido su conductividad electrónica y protónica. Estos cristalizan en diferentes ... -
Alite hydration mechanism in presence of ye’elimite related to BAY cements
(2019-10-08)One alternative to decrease CO2 emissions from ordinary Portland Cement (OPC) production consists on the development of a new kind of eco-cements composed by less calcite demanding phases. That is the case of ... -
Ammonia effects on proton conductivity properties of coordination polymers
(2016-09-22)Crystalline metal phosphonates are referred to as a type of structurally versatile coordination polymers [1]. Many of them contain guest molecules (H2O, heterocyclics, etc.), acidic sites and, furthermore, their structure ... -
ANALYSIS OF BUILDING MATERIALS BY SYNCHROTRON X-RAY IMAGING
(-, 2021-01)Building materials have complex hierarchical microstructures. The largest components are coarse aggregates with dimensions larger than a few centimetres and the smallest ones are the calcium silicate hydrate (C-S-H) gel ... -
Analysis of cementitious building materials by synchrotron x-ray imaging
(2022)Cement manufacturing especially Portland Cement, the main component for the fabrication of concretes, is the most used building and construction material which has complex hierarchical microstructures. Quantitative ... -
Aplicación de estrategias de aprendizaje para la adquisición de competencias profesionales y su evaluación mediante una rúbrica integradora en diversos títulos de grado de la Universidad de Málaga
(2015-07-28)El Espacio Europeo de Educación Superior ha supuesto importantes cambios en el proceso de enseñanza-aprendizaje para la adquisición de competencias transversales y específicas. La calidad es un factor estratégico, por lo ... -
Applications of synchrotron x-ray powder diffraction in hydrated cements: high-resolution and high-pressure studies
(2016-07-12)The main aim of this study is to apply synchrotron radiation techniques for the study of hydrated cement pastes. In particular, the tetracalcium aluminoferrite phase, C4AF in cement nomenclature, is the major iron-containing ... -
Asociación talco-fengita en esquistos blancos de la Zona Interna del Rif, Norte de Marruecos
(Sociedad Española de Mineralogía, 2019)La asociación talco-fengita como indicador de condiciones metamórficas de HP se conoce desde la publicación de Abraham y Schreyer (1976). Los estudios experimentales y teóricos han demostrado que esta asociación es estable ... -
Au-Cu/SBA(Ti) based catalysts for photocatalytic applications
(2018-06)In this work, it has been synthesized several Au and Au-Cu alloy photocatalysts supported on two different mesoporous supports: a non-commercial SBA-15 and a post-synthesis TiO2 modified SBA-15 (TiSBA-15), with which a ... -
Behavior of Belite cement blended with Calcium sulfoaluminate cement: an Ecocement
(2019-09-26)Belite Portland Cements (BPC) and calcium sulfoaluminate cements (CSA) are considered as environmentally friendly cements due to their lower CO2 emissions. These ecocements (BPC and CSA) emit about 0.03 and 0.18 less tons ... -
