The 2021 room-temperature superconductivity roadmap
(IOP, 2022-03-03)
Designing materials with advanced functionalities is the main focus of contemporary solid-state physics and chemistry. Research efforts worldwide are funneled into a few high-end goals, one of the oldest, and most fascinating ...
Excitonic insulator to superconductor phase transition in ultra-compressed helium
(Springer Nature, 2023-07-25)
Helium, the second most abundant element in the universe, exhibits an extremely large electronic band gap of about 20 eV at ambient pressures. While the metallization pressure of helium has been accurately determined, thus ...
Fabrication and characterization of active polymer optical fibers with a ring-doped structure
(Elsevier, 2023-01)
This paper employs the solution-doping technique for the fabrication of polymer optical fibers (POFs) doped with two perylene derivatives, Lumogen Yellow 083 and Lumogen Red 305, in different combinations. With the ...
Optically active nano-glass-ceramic coatings of Nd3+ doped-80SiO2-20LaF3 prepared by the pre-crystallized nanoparticles sol-gel route
(Elsevier, 2023-02)
Transparent oxyfluoride glass-ceramic (OxGCs) coatings with composition 1.2Nd3+ 80SiO2- 20LaF3 were prepared following a sol-gel route labelled “pre-crystallized nanoparticles route”. OxGCs are transparent materials composed ...
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 ...
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 ...
