Influence of internal flexibility on the double glass transition in a series of odd non-symmetric liquid crystal dimers characterised by dielectric measurements
Diego Vives, José Antonio; Sellarès González, Jordi; Díez Berart, Sergio; Salud Puig, Josep; Cañadas Lorenzo, Juan Carlos; Mudarra López, Miguel; López Pérez, David Orencio; de la Fuente Lavin, Maria Rosario; Ros, M Blanca (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 ... -

Space charge measurements in XLPE insulated mid-voltage cable: correlation with cable performance
Tamayo Ávila, Idalberto; Orrit Prat, Jordi; Diego Vives, José Antonio (2007)
Comunicació de congrés
Accés restringit per política de l'editorialThree experimental midvoltage XLPE cables, C2, C3 and C4, rated respectively as 'good', 'very good' and 'bad' in perforation tests, are studied. All these cables have been systematically measured by PEA as produced and ... -
Study of dispersive mobility in polyimide by surface voltage decay measurements
Aragoneses Aguado, Andrés; Mudarra López, Miguel; Belana Punseti, Juan; Diego Vives, José Antonio (ELSEVIER PUBLISHER, 2008-05)
Article
Accés obertIn order to study charge trapping and transport in polyimide, we have submitted samples of Kapton HN to corona charging and measured its surface potential decay with an electrostatic voltmeter. We propose a two terms ... -
Sublinear dispersive conductivity in polyetherimides by the electric modulus formalism
Mudarra López, Miguel; Sellarès González, Jordi; Cañadas Lorenzo, Juan Carlos; Diego Vives, José Antonio (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 ... -
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
Díez Berart, Sergio; López Pérez, David Orencio; Salud Puig, Josep; Diego Vives, José Antonio; Sellarès González, Jordi; Robles Hernández, Beatriz; De la Fuente, Maria Rosario; Blanca Ros, María (2015-06-01)
Article
Accés obertIn 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 ...
