Study analysis of thermal, dielectric and functional characteristics of an ethylene polyethylene diene monomer blended with end-of-life tire microparticles amounts
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-02-02)
Article
Accés obertThe recycling and disposal of disused tires is a topic of great concern to today’s companies, researchers, and society in general. In this sense, our research aims to recycle end-of-life tires (GTRs) through the separation ... -
Comparative study of mechanical and electrical relaxations in poly(etherimide). Part 2

Accés restringit per política de l'editorialThe curves describing the relaxation behaviour of poly(etherimide) at several frequencies shows in the dielectric lossÈtemperature plot c and b relax- ations centred at [95¡C and 100¡C, respectively, at 10 Hz. The glassÈrubber ... -
Influence of Polymethylmethacrylate microstructure on its conductive properties at high temperature
(2019)
Article
Accés obertThe influence of a set of tacticity-governed microstructures on the conductive properties of poly(methyl methacrylate) has been studied at high temperatures. Those structures are specially the mmmr and the mmmmrx (x = m ... -
Charge storage and retention in electret dielectric layers for energy harvesting applications
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialBy providing a permanent electric polarization, electrets have a wide range of applications in different fields like sensors and actuators, energy harvesting or biomedicine. Stable electrets with silicon-based compatible ... -
Effects of UV radiation on the charge trapping capability of PET
(Institute of Physics (IOP), 2019-02-06)
Article
Accés obertPoly(ethylene terephthalate) (PET) is able to retain space charge in traps, as is usual in dielectric materials. This allows the material to attain an almost permanent polarization when space charge is displaced by an ... -
Influence of internal flexibility on the double glass transition in a series of odd non-symmetric liquid crystal dimers characterised by dielectric measurements
(2017-04-11)
Article
Accés obertDielectric measurements (thermally stimulated depolarisation currents and broadband dielectric spectroscopy) have been performed near the glass transition to study the glass transition on the odd non-symmetric liquid crystal ... -
Experimental study of different LFF regimes in semiconductor lasers with an external cavity
(2011)

A new approach to design an efficient micropost array for enhanced direct-current insulator-based dielectrophoretic trapping
(2016-07)
Article
Accés obertDirect-current insulator-based dielectrophoresis (DC-iDEP) is a well-known technique that benefits from the electric field gradients generated by an array of insulating posts to separate or trap biological particles. The ... -
Study of the charge profile of thermally poled electrets
(2016-02-17)
Report de recerca
Accés obertThe charge profile of thermally poled electrets has been studied using two different methods, laser induced pressure pulse (LIPP) and pulsed electroacoustic (PEA), to gain insight into the mechanisms that are activated and ... -
Confección y gestión automática de exámenes tipo test

Accés restringit per política de l'editorialEl presente trabajo describe la implementación de una aplicación informática como recurso docente, diseñada como plataforma para la elaboración, utilización y corrección de controles formativos y exámenes de evaluación. ... -
Accreditation of Spanish Engineering Programs, first experiences. The case of the Terrassa School of Engineering
(2016)
Article
Accés obertThe implementation of the European Space for Higher Education has entailed new requirements for Spanish Higher Education Programs. Regulations (RD 1393, 2007) stablish that university programs, in order to have official ... -
Sublinear dispersive conductivity in polyetherimides by the electric modulus formalism
(2015-12)
Article
Accés obertTwo commercially available polyetherimides, Ultem 1000 and Ultem 5000, have been studied by means of Dynamic Electrical Analysis. Results show that at temperatures above the glass transition dielectric response is highly ...
