Optical Characterization of Doped Thermoplastic and Thermosetting Polymer-Optical-Fibers
(MDPI, 2017-03)
The emission properties of a graded-index thermoplastic polymer optical fiber and a step-index thermosetting one, both doped with rhodamine 6G, have been studied. The work includes a detailed analysis of the amplified ...
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 ...
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 ...
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 ...
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, ...
Contribution to material thermal characterization techniques and subsurface defect detection using infrared thermography and other imaging methods.
(2017-05-25)
Esta tesis doctoral utiliza métodos de generación de imágenes para estudiar la difusión de calor en una muestra. Dos variantes principales fueron empleadas. La primera utiliza variaciones en el índice de refracción, inducidas ...
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 ...
On-surface synthesis and electronic structure characterization of grafphene nanoribbons.
(2019-11-12)
Esta tesis expone un estudio detallado sobre la síntesis en superficie de nanotiras de grafeno (en inglés 'Graphene Nanoribbons', GNRs) y la posterior caracterización de su estructura electrónica, principalmente empleando ...
