A site-selective fluorescence spectroscopy study of the crystal phases of KY3F10: Leveraging the optical response of Eu3+ ions
(Elsevier, 2023-08)
The present work deals with the investigation of the site-selective symmetries in Eu3+-doped KY3F10 with different crystal phases. Employing time-resolved fluorescence line-narrowing (TRFLN), a study of the luminescent ...
Synthesis, magnetism and reactivity of graphene nanoribbons

En esta tesis profundizaremos se enfoca desde un ángulo fundamental la ciencia de las cintas de grafenoPrimero se definirán sus propiedades basándose en ideas bien fundamentadas como la aromaticidad yla topología. Una vez ...
EANM enabling guide: how to improve the accessibility of clinical dosimetry
(Springer, 2023-06)
Dosimetry can be a useful tool for personalization of molecular radiotherapy (MRT) procedures, enabling the continuous development of theranostic concepts. However, the additional resource requirements are often seen as a ...
Ab initio study of the structural, vibrational, and optical properties of potential parent structures of nitrogen-doped lutetium hydride
(APS, 2023-08-28)
The recent report of near-ambient conditions superconductivity in a nitrogen-doped lutetium hydride has inspired a large number of experimental studies with contradictory results. We model from first principles the physical ...
Convective Vortices and Dust Devils Detected and Characterized by Mars 2020
(American Geophysical Union, 2023-02)
We characterize vortex and dust devils (DDs) at Jezero from pressure and winds obtained with the Mars Environmental Dynamics Analyzer (MEDA) instrument on Mars 2020 over 415 Martian days (sols) (Ls = 6°–213°). Vortices are ...
van der Waals driven anharmonic melting of the 3D charge density wave in VSe2
(Nature, 2021-01-27)
Understanding of charge-density wave (CDW) phases is a main challenge in condensed matter due to their presence in high-Tc superconductors or transition metal dichalcogenides (TMDs). Among TMDs, the origin of the CDW in ...
Anharmonicity Reveals the Tunability of the Charge Density Wave Orders in Monolayer VSe2
(American Chemical Society, 2023-02)
VSe2 is a layered compound that has attracted great attention due to its proximity to a ferromagnetic state that is quenched by its charge density wave (CDW) phase. In the monolayer limit, unrelated experiments have reported ...
Redox regulation of KV7 channels through EF3 hand of calmodulin
(eLife Sciences, 2023-01)
Neuronal KV7 channels, important regulators of cell excitability, are among the most sensitive proteins to reactive oxygen species. The S2S3 linker of the voltage sensor was reported as a site-mediating redox modulation ...
Winds at the Mars 2020 Landing Site. 2. Wind Variability and Turbulence
(American Geophysical Union, 2022-12)
Wind speeds measured by the Mars 2020 Perseverance rover in Jezero crater were fitted as a Weibull distribution. InSight wind data acquired in Elysium Planitia were also used to contextualize observations. Jezero winds ...
Charge and spin state of dilute Fe in NaCl and LiF
(American Physical Society, 2022-11)
There is an apparent mismatch between electron paramagnetic resonance and Mössbauer spectroscopy results on the charge and spin states of dilute Fe impurities in NaCl; Mössbauer spectroscopy data have been interpreted in ...
