Children’s Pictorial Expression of Plant Life and Its Connection with School-Based Greenness
(MDPI, 2021-04-29)
Previous research highlights the positive influence that experiences in nature have on children’s physical, emotional and conceptual development. There is also evidence that indicates that the availability of green areas ...
Influence of Cryogenic Treatment on Wear Resistance and Microstructure of AISI A8 Tool Steel
(MDPI, 2018-12)
The effects of deep cryogenic treatment (DCT) on the wear behavior of different tool steels have been widely reported in the scientific literature with uneven results. Some tool steels show a significant improvement in ...
Dynamics of saturn's polar regions
(2017-09-26)
En esta tesis, estudiamos la dinámica de las regiones polares de Saturno a nivel de las nubes de amoniaco desde 60º a 90º latitud mediante el análisis de imágenes multiespectrales de muy alta resolución capturadas por las ...
Strong correlation between electronic bonding network and critical temperature in hydrogen-based superconductors
(Nature Research, 2021-09-16)
By analyzing structural and electronic properties of more than a hundred predicted hydrogen-based superconductors, we determine that the capacity of creating an electronic bonding network between localized units is key to ...
Upconversion cooling of Er-doped low-phonon fluorescent solids
(American Physical Society, 2009-01)
We report on a novel mechanism for laser cooling of fluorescent solids based on infrared-to-visible upconversion often found in rare-earth-doped low-phonon materials. This type of optical cooling presents some advantages ...
Anomalous High‐Temperature Superconductivity in YH6
(Wiley-VCH GmbH, 2021-03-10)
Pressure‐stabilized hydrides are a new rapidly growing class of high‐temperature superconductors, which is believed to be described within the conventional phonon‐mediated mechanism of coupling. Here, the synthesis of one ...
Strong anharmonic and quantum effects in Pm-3n AlH3 under high pressure: A first-principles study
(APS, 2021-04-29)
Motivated by the absence of experimental superconductivity in the metallic Pm-3n phase of
AlH3 despite the predictions, we reanalyze its vibrational and superconducting properties at pressures
P≥99 GPa making use of ...
Designing periodic and aperiodic structures for nanophotinic devices.
(2019-05-22)
Future all--optical networks will require to substitute the present electronic integrated circuitry by optical analogous devices that satisfy the compactness, throughput, latency and high transmission efficiency requirements ...
Exploring the Different Degrees of Magnetic Disorder in TbxR1−xCu2 Nanoparticle Alloys
(MDPI, 2020-10-28)
Recently, potential technological interest has been revealed for the production of magnetocaloric alloys using Rare-Earth intermetallics. In this work, three series of TbxR1−xCu2 (R ≡ Gd, La, Y) alloys have been produced ...
Characterization of hydrogen based superconductors from first principles
(2022-12-16)
En esta tesis, primero se realiza una investigación de las propiedades químicas, estructurales y electrónicas de un gran conjunto de superconductores binarios basados en hidrógeno, a través de métodos ab initio basados en ...
