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 ...
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 ...
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 ...
Dificultades de aprendizaje del modelo de sonido: una revisión de la literatura
(Universitat Autónoma de Barcelona, 2021-06)
Learning the scientific model of sound (ScMS) is present in the science curriculum of all educational levels and is a critical component of scientific literacy. This paper presents a systematic review of students' understanding ...
Downscaling of surface moisture flux and precipitation in the Ebro Valley (Spain) using analogues and analogues followed by random forests and multiple linear regression
(Copernicus Gesellschaft, 2011)
In this paper, reanalysis fields from the ECMWF have been statistically downscaled to predict from large-scale atmospheric fields, surface moisture flux and daily precipitation at two observatories (Zaragoza and Tortosa, ...
Characterizing Subsurface Rectangular Tilted Heat Sources Using Inductive Thermography
(MDPI, 2020-08-06)
In this study, we characterize the lateral dimension, depth, and inclination of buried tilted rectangular heat sources from time domain temperature data measured at the surface. The heat sources are representative for ...
Vertical Cracks Excited in Lock-in Vibrothermography Experiments: Identification of Open and Inhomogeneous Heat Fluxes
(MDPI, 2022-03-17)
Lock-in vibrothermography has proven to be very useful to characterizing kissing cracks producing ideal, homogeneous, and compact heat sources. Here, we approach real situations by addressing the characterization of ...
