    • A new approach to design an efficient micropost array for enhanced direct-current insulator-based dielectrophoretic trapping 

      Mohammadi, Mahdi; Javad Zare, Mohammad; Madadi, Hojjat; Sellarès González, Jordi; Casals Terré, Jasmina (2016-07)
      Article
      Accés obert
      Direct-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 ...

    • Charge storage and retention in electret dielectric layers for energy harvesting applications 

      Diáz-Ballester, A.; Castillo-Anguera, S; Rafi, J. M.; Gómez-Martínez, R.; Abadal, G.; Figueras, E.; Plaza, J.A.; Esteve, J.; Mudarra López, Miguel; Cañadas Lorenzo, Juan Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2014)

      Accés restringit per política de l'editorial
      By 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 ...

    • Dielectric and mechanical nonlinear behavior of Mn doped PMN-35PT ceramics 

      Kobor, Diouma; Hajjaji, Abdelowahed; García García, José Eduardo; Pérez Pérez, Rafael; Albareda Tiana, Alfonso; Lebrun, Laurent; Guyomar, Daniel (2010-10)
      Article
      Accés obert
      This paper presents an investigation on dielectric and mechanical nonlinear properties in Mn-doped PMN-35PT ceramics. The structural study of the ceramics verifies that the 1% mol Mn doped PMN-35PT is a pure perovskite ...

    • Efficient analysis of homogeneous dielectric and plasmonic media with integral equation MEI (IE-MEI) 

      Rius Casals, Juan Manuel; Planes Conangla, Gerard; Úbeda Farré, Eduard; Heldring, Alexander (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This paper revisits the IE-MEI method and proposes a new formulation for high-loss dielectric piecewise-homogeneous media. The aim of this work is to assess if the fast attenuation of fields in highly lossy media helps in ...

    • Propiedades dieléctricas y transición de fase del sistema BZT modificado con tierras raras 

      Boya Pimentel, Aurelio (Universitat Politècnica de Catalunya, 2010-06-17)
      Projecte Final de Màster Oficial
      Accés obert
      En este trabajo se ha investigado la influencia de la adición de tierras raras sobre la transición de fase y las propiedades dieléctricas del titanato circonato de bario, Ba(ZrxTi1-x)O3 (BZT). Las muestras fueron obtenidas ...

    • Study of the critical behavior and scaling relationships at the N-to-I phase transition in hexyloxycyanophiphenyl 

      Salud Puig, Josep; Cusmin, Paul; Fuente, M.R. de la; Pérez Jubindo, M.A.; López Pérez, David Orencio; Díez Berart, Sergio (2009-10-07)
      Article
      Accés restringit per política de l'editorial
      An exhaustive analysis of the critical behavior of the nematic to isotropic (N-to-I) phase transition on the liquid crystal hexyloxycyanobiphenyl (6OCB) has been performed. To do so, the accurate evolution of various physical ...
