Metal-Doping of La5.4MoO11.1 Proton Conductors: Impact on the Structure and Electrical Properties.
(American Chemical Society, 2018-10-03)La5.4MoO11.1 proton conductors with different metal doping (Ca2+, Sr2+, Ba2+, Ti4+, Zr4+, and Nb5+) have been prepared and structurally and electrically characterized. Different polymorphs are stabilized depending on ... -
Metallic ceramics: a new "Old generation" of catalysts with tunable selectivity
(2017-03-06)One of the key conditions for a successful catalytic process is the catalyst itself. This apparently naïve assertion in fact holds a great implication, such as the possibility to have a fine control on crucial chemical ... -
Metamaterial antenna array fed by distributed Bragg deflector for beam steering on SOI platform
(2023)The capability to radiate collimated steerable beams of light is crucial for many applications, such as remote sensing and free-space optical communications. Here we experimentally demonstrate a novel 1D-antenna array ... -
Metamaterial antenna array fed by distributed Bragg deflector for SOI platform
(2022)We propose a distributed Bragg deflector working as a low loss (<0.3 dB) ultra compact beam expander, which generates an on chip Gaussian beam that illuminates a 1D array of 112 optical antennas with a length of 1.5 mm . ... -
Metamaterial engineered C+L band 90º hybrid with 150 nm feature size
(2020-09-28)90º hybrids are important components for coherent optical communications. Conventional implementations only cover the C band, while broadband, metamaterial-based devices require sub-100nm feature sizes. We propose a ... -
Metamorfosis de una invención. Turismo y clase creativa: el caso de la Costa del Sol en el mediterráneo español.
(Servicio de Publicaciones y Divulgacion Cientifica, 2016)Algunos destinos turísticos han incrementado su conectividad externa e interna, por lo que se convierten en zonas de transición entre la ciudad global y el territorio local, siendo lugares que mezclan las tendencias de ... -
Metapopulation Patterns of Iberian Butterflies Revealed by Fuzzy Logic
(MDPI, 2021-04)Metapopulation theory considers that the populations of many species are fragmented into patches connected by the migration of individuals through an interterritorial matrix. We applied fuzzy set theory and environmental ... -
Methane concentration and isotopic composition (d13C-CH4) in the Nerja Cave system (South Spain)
(2016-04-26)Air in underground caves often has methane (CH4) concentrations below the atmospheric level, due to methanotrophic or other unkown CH4 consuming processes. Caves are thus considered a potential sink for atmospheric methane. ... -
Methanol dehydration on carbon-based acid catalysts
(XXXIV Reunión Bienal de la Real Sociedad Española de Química, 2013-09-16)Methanol dehydration to produce dimethyl ether (DME) is an interesting process for the chemical industry since DME is an important intermediate and a promising clean alternative fuel for diesel engines. Pure or modified ... -
Methanol dehydration over ZrO2 supported-activated carbons
(Asociación Nacional de Químicos de España, 2016)DME is playing an important role due to its potential use as an alternative fuel in diesel engines. The use of this fuel produces lower NOx emissions, and less engine noise compared to traditional diesel fuels. Moreover, ... -
Methionine Cycle Rewiring by Targeting miR-873-5p Modulates Ammonia Metabolism to Protect the Liver from Acetaminophen
(IOAP-MPDI, 2022-04-30)Drug-induced liver injury (DILI) development is commonly associated with acetaminophen (APAP) overdose, where glutathione scavenging leads to mitochondrial dysfunction and hepatocyte death. DILI is a severe disorder without ... -
Method for Automatically Extracting of Tourism Destination Image from Chinese Social Networks. The case of Spain.
(UMA Editorial, 2016)La creciente importancia de las redes sociales (RRSS) como fuente de información de opiniones turísticas y el auge del mercado chino son las dos razones que justifican este trabajo. Revisando los estudios de los últimos ... -
Methodological advances in the analysis, assessment and intervention of industrial landscapes
(2018-10-04)We are currently witnessing a gradual extension of the concept of heritage. This idea has evolved to encompass landscapes and is even reaching into an area which, until recently, had not received sufficient attention: ... -
