Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

open access: yesAdvanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

LOS PARTIDOS TRASNACIONALES EN ESPAÑA. EL CASO DE LOS PARTIDOS RUMANOS / THE TRANSNATIONAL PARTIES IN SPAIN. THE CASE OF THE ROMANIAN PARTIES

open access: yesBarataria, 2017
Based on the studies on the socio-political aspect of transnationality, this research analyzes two exogenously designed political organizations (promoted and coordinated from a supralocal or supra-national scope and space), inspired by the existence of ...

Immigration in the Spanish nation

open access: yesTensões Mundiais, 2018
The literature suggests that Spain has never had a national identity but is rather an amalgam of regional identities. The accession to the European Union and the arrival of immigrants present new challenges to Spanish identity. Forging a national identity entails both building a solidarity based on ‘belongingness’ and excluding certain groups that ...

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

open access: yesAdvanced Functional Materials, EarlyView.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...
