    • Disseny d'un tanc d'escalfament per inducció per a materials no ferromagnètics 

      Duran i Reus, Francesc Xavier (Universitat Politècnica de Catalunya, 2013-11)
      Projecte/Treball Final de Carrera
      Accés obert
      La inducci o electromagn etica va ser descoberta el 1831 per Michael Faraday. Des de llavors, aquest fen omen ha estat investigat i estudiat en un ampli ventall d'aplicacions, com ara motors el ectrics, transformadors el ...
    • Giant solid-state barocaloric effect in the Ni-Mn-In magnetic shape-memory alloy 

      Mañosa, Lluís; Gonzalez Alonso, David; Planes, Antoni; Bonot, Erell; Barrio Casado, María del; Tamarit Mur, José Luis; Aksoy, Seda; Acet, Mehmed (2010-06-01)
      Article
      Accés obert
      Solid-state materials showing giant caloric effects near room temperature could provide an alternative to cooling devices based on gas cycles. Strong emphasis has so far been dedicated to caloric effects induced by a ...
    • Magnet shape influence on the performance of AFPMM with demagnetization 

      Saavedra Ordóñez, Harold; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (IEEE Industrial Electronics Society, 2013)
      Text en actes de congrés
      Accés obert
      In this paper the effect of the magnets shape on the AFPMM performance under a demagnetization fault has been analyzed by means of 3D-FEM simulations. Demagnetization faults in permanent magnet synchronous motors (PMSMs) ...
    • Magnetite-supported palladium single-atoms do not catalyse the hydrogenation of alkenes but small clusters do 

      Rosell, Marta D.; Caparrós, Francisco J.; Angurell Purroy, Inmaculada; Müller Jevenois, Guillermo; Llorca Piqué, Jordi; Seco García, Miquel Angel; Rosell, Oriol (2016-01-01)
      Article
      Accés obert
      The activity of supported noble metal catalysts strongly depends on the particle size. The ultimate small-size limit is the single-atom catalyst (SAC), which maximizes the catalytic efficiency in the majority of the examples. ...
    • Modelling magnetostructural textures in magnetic shape-memory alloys: Strain and magnetic glass behaviour 

      Lloveras Muntané, Pol Marcel; Touchagues, Gilles; Castán, Teresa; Lookman, Turab; Porta, Marcela; Saxena, Avadh; Planes Vila, Antoni (2014-10-01)
      Article
      Accés restringit per política de l'editorial
      In this paper, we propose a model that combines a Landau free energy part and a micromagnetic free energy part aimed at describing a magnetostructural multiferroic. We show that in the limit of high-elastic anisotropy and ...
    • Optimal design of a three-phase AFPM for in-wheel electrical traction 

      Saavedra Ordóñez, Harold; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (2014)
      Comunicació de congrés
      Accés obert
      Sinusoidally fed permanent magnet synchronous motors (PMSM) fulfill the special features required for traction motors to be applied in electric vehicles (EV). Among them, axial flux permanent magnet (AFPM) synchronous ...
