Crank-Nicholson method for rate equations in powder random lasers
(IOP Publishing, 2015)
In this work, we show the resolution of the rate equations in powder random lasers by using the Crank-Nicholson finite difference method. Light propagation in our powders is described by the model of light diffusion. The ...
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 ...
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 ...
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 ...
Optimization of solution-processed oligothiophene:fullerene based organic solar cells by using solvent additives
(Beilstein Institut, 2013-10)
The optimization of solution-processed organic bulk-heterojunction solar cells with the acceptor-substituted quinquethiophene DCV5T-Bu-4 as donor in conjunction with PC61BM as acceptor is described. Power conversion ...
STM study on the self-assembly of oligothiophene-based organic semiconductors
(Beilstein Institut, 2011-11)
The self-assembly properties of a series of functionalized regioregular oligo(3-alkylthiophenes) were investigated by using scanning tunneling microscopy (STM) at the liquid-solid interface under ambient conditions. The ...
Surface state tunable energy and mass renormalization from homothetic quantum dot arrays
(Royal Society of Chemistry, 2019-12-28)
Quantum dot arrays in the form of molecular nanoporous networks are renowned for modifying the electronic surface properties through quantum confinement. Here we show that, compared to the pristine surface state, the band ...
Vibron-assisted spin excitation in a magnetically anisotropic molecule
(Nature, 2020-04)
The electrical control and readout of molecular spin states are key for high-density storage. Expectations are that electrically-driven spin and vibrational excitations in a molecule should give rise to new conductance ...
Long-term Variations of Venus's 365 nm Albedo Observed by Venus Express, Akatsuki, MESSENGER, and the Hubble Space Telescope
(IOP, 2019-08-26)
An unknown absorber near the cloud-top level of Venus generates a broad absorption feature from the ultraviolet (UV) to visible, peaking around 360 nm, and therefore plays a critical role in the solar energy absorption. ...
