Restricted access - publisher's policyThe 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
Open AccessThe 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 ... -
Effects of UV radiation on the charge trapping capability of PET
(Institute of Physics (IOP), 2019-02-06)
Article
Open AccessPoly(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
Open AccessDielectric 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 ... -
A new approach to design an efficient micropost array for enhanced direct-current insulator-based dielectrophoretic trapping
(2016-07)
Article
Open AccessDirect-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 ... -
Accreditation of Spanish Engineering Programs, first experiences. The case of the Terrassa School of Engineering
(2016)
Article
Open AccessThe 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
Open AccessTwo 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 ... -

(2015-06-01)
Article
Restricted access - author's decisionEvaluation and diagnosis of blood alterations is a common request for clinical laboratories, requiring a complex technological approach and dedication of health resources. In this paper, we present a microfluidic device ... -
Two glass transitions associated to different dynamic disorders in the nematic glassy state of a non-symmetric liquid crystal dimer dopped with gamma-alumina nanoparticles
(2015-06-01)
Article
Open AccessIn the present work, the nematic glassy state of the non-symmetric LC dimer -(4-cyanobiphenyl-4-yloxy)--(1-pyrenimine-benzylidene-4-oxy) undecane is studied by means of calorimetric and dielectric measurements. The most ... -
