Ethanol-derived graphene by microwave plasma torch as efficient cathode for Li-S batteries with ultralong cycle life
(Elsevier, 2025)High-quality graphene derived from ethanol (EdG) using an atmospheric pressure plasma torch has been used for the first time as a sulfur host for lithium-sulfur (Li-S) battery cathodes. Its excellent structural, morphological, ... -
Evaluación y mitigación del impacto oloroso en la gestión de residuos urbanos: contenedores inteligentes
(2024)La contaminación atmosférica urbana es uno de los problemas más graves de contaminación a nivel mundial (IPCC, 2013). La ley 7/2022 establece la necesidad de adoptar medidas para la protección de la salud humana y medio ... -
Evidence for baryon acoustic oscillations from galaxy–ellipticity correlations
(Springer, 2023)The Baryon Acoustic Oscillations (BAO) feature in the clustering of galaxies or quasars provides a "standard ruler" for distance measurements in cosmology. In this work, we report a 2∼3σ signal of the BAO dip feature in ... -
Exact stark analytical function for Hα line based on the FFM model related with plasma parameters
(Elsevier, 2024)Optical Emission Spectroscopy is a widely used technique for plasma diagnosis, with particular interest in hydrogen atomic emission due to its prevalence in plasmas. However, accurately determining plasma parameters like ... -
Exclusion Principle Repulsion Effects on the Covalent Bond Beyond the Born-Oppenheimer Approximation
(Royal Society of Chemistry, 2019)The changes in the covalent bond of the hydrogen molecule limited in the space by a spherical hard boundary are studied. The sphere is moved along an axis parallel or orthogonal to the molecular axis. The diffusion Monte ... -
Experimental characterization of TIAGO torch discharges: surface wave discharge behavior and (post-)discharge kinetics
(IOP Publishing, 2023)The Torche à Injection Axial sur Guide d'Ondes source—better-known as the TIAGO torch—is a particular type of microwave-induced plasma that has become a focus of technological and scientific interest due to its outstanding ... -
