Active and Passive Tuning of Ultranarrow Resonances in Polaritonic Nanoantennas
(Wiley, 2022-03-10)
[EN] Optical nanoantennas are of great importance for photonic devices and spectroscopy due to their capability of squeezing light at the nanoscale and enhancing light-matter interactions. Among them, nanoantennas made of ...
Planar refraction and lensing of highly confined polaritons in anisotropic media
(Nature, 2021-07-15)
Refraction between isotropic media is characterized by light bending towards the normal to the boundary when passing from a low- to a high-refractive-index medium. However, refraction between anisotropic media is a more ...
Elemental imaging approach to assess the ability of subaerial biofilms growing on constructions located in tropical climates as potential biomonitors of atmospheric heavy metals pollution
(Elsevier, 2022-10-06)
Over the last decades, the concern about air pollution has increased significantly, especially in urban areas. Active sampling of air pollutants requires specific instrumentation not always available in all the laboratories. ...
Resumen ejecutivo del documento de consenso para la prevención de los trastornos de la conducta alimentaria SENPE-SENC-SEPEAP-SEMERGEN
(Arán, 2022)
Los TCA configuran un grupo de problemas de salud en los que la insatisfacción con la imagen corporal se combina con alteraciones en la conducta alimentaria, baja autoestima, problemas de perfeccionismo, depresión o ansiedad ...
How Aromatic Are Molecular Nanorings? The Case of a Six-Porphyrin Nanoring**
(Wiley, 2021-11-02)
Large conjugated rings with persistent currents are novel promising structures in molecular-scale electronics. A six-porphyrin nanoring structure that allegedly sustained an aromatic ring current involving 78 pi electrons ...
Decades of biomass loss in the shallow rocky subtidal vegetation of the south-eastern Bay of Biscay
(Springer, 2022)
[EN] This study seeks to assess changes over time in the structure of subtidal macroalgal assemblages across depth in the south-eastern Bay of Biscay. The results reveal a large-scale decline in total macroalgal biomass ...
Characterization of the contamination fingerprint of wastewater treatment plant effluents in the Henares River Basin (central Spain) based on target and suspect screening analysis
(Elsevier, 2022-02-01)
The interest in contaminants of emerging concern (CECs) has increased lately due to their continued emission and potential ecotoxicological hazards. Wastewater treatment plants (WWTPs) are generally not capable of eliminating ...
A Great Step Forward. Lithic Raw Material Procurement and Management among Palaeolithic Hunter -Gatherers in the Basque Crossroads
(School of History, Classics and Archaeology, University of Edinburgh, 2020)
This paper is divided into three sections. The first section describes the historiographic evolution of the study of prehistoric lithic raw materials in the Basque Crossroads (in the north of the Iberian Peninsula) during ...
Acetoxymethyl-BODIPY dyes: a universal platform for the fluorescent labeling of nucleophiles
(Royal Society of Chemistry, 2022)
Current methods for the preparation of functional small-molecule fluorophores generally require labor-intensive, multi-step synthetic routes for all the major chromophoric groups. In spite of recent significant contributions ...
Assessing Autophagy in Microglia: A Two-Step Model to Determine Autophagosome Formation, Degradation, and Net Turnover
(Frontiers Media, 2021-01-29)
Autophagy is a complex process that encompasses the enclosure of cytoplasmic debris or dysfunctional organelles in membranous vesicles, the autophagosomes, for their elimination in the lysosomes. Autophagy is increasingly ...
