Fabrication of Active Polymer Optical Fibers by Solution Doping and Their Characterization
(MDPI, 2018-12-31)
This paper employs the solution-doping technique for the fabrication of active polymer optical fibers (POFs), in which the dopant molecules are directly incorporated into the core of non-doped uncladded fibers. Firstly, ...
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 ...
POF-Based Solar Concentrators Incorporating Dyes and Europium Chelates
(MDPI, 2021-05-19)
In this paper, useful models that enable time-efficient computational analyses of the performance of luminescent solar concentrators (LSCs) are developed and thoroughly described. These LSCs are based on polymer optical ...
Effects of Fabrication Methods on the Performance of Luminescent Solar Concentrators Based on Doped Polymer Optical Fibers
(MDPI, 2021-01-28)
In this work, we detail two types of fabrication processes of four polymer optical fibers doped with lumogen dyes. The fiber preforms have been manufactured with two different methods: extrusion and casting. We have compared ...
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 ...
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 ...
Diseño iterativo de una secuencia de enseñanza-aprendizaje sobre el pricipio generalizado del trabajo y la energía en cursos universitarios de física general
(2018-07-23)
Las relaciones entre trabajo y energía en el currículum de mecánica para cursos de física a nivel introductorio en la Universidad, juegan un papel crucial en la comprensión de los estudiantes del mundo físico y su aplicación ...
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 ...
