Absence of sizable superconductivity in hydrogen boride: A first-principles study
(APS, 2022-12-12)
The recently synthesized hydrogen boride monolayer in the Cmmm phase is a promising superconductor due to its similarity to MgB2 and the large hydrogen content in its structure. Making use of first-principles calculations ...
Structure Matters: Asymmetric CO Oxidation at Rh Steps with Different Atomic Packing
(American Chemical Society, 2022-08)
Curved crystals are a simple but powerful approach to bridge the gap between single crystal surfaces and nanoparticle catalysts, by allowing a rational assessment of the role of active step sites in gas-surface reactions. ...
Sustainable Cultural Tourism in Urban Destinations: Does Space Matter?
(MDPI, 2016-07)
Policy makers and tourism developers must understand visitors' mobility behavior and how they consume space and tourism resources in order to set up sustainable cultural tourism destinations. With this in mind, it should ...
New algorithm for the elucidation of functional properties of gelatin-based materials
(Pergamon-Elsevier, 2021-10)
In the present work, fish gelatin was employed to develop renewable and biodegradable materials, reducing environmental problems associated with conventional petroleum-based materials. Glycerol was used as plasticizer and ...

(2022-11-25)
Júpiter, el mayor planeta del Sistema Solar, presenta una atmósfera permanentemente cubierta por nubes donde se desarrollan una gran variedad de fenómenos atmosféricos. El estudio de la dinámica atmosférica de Júpiter ...
Ab initio study of metastable occupation of tetrahedral sites in palladium hydrides and its impact on superconductivity
(APS, 2023-01-11)
A recent experimental work on palladium hydrides suggested that metastable structures with hydrogen atoms occupying tetrahedral sites could lead to superconductivity above 50 K, a huge increase compared to the 9 K critical ...
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 ...
