    • Extruded catalysts with magnetic properties for biodiesel production 

      Silveira Junior, Euripedes Garcia; Justo, Oselys Rodriguez; Perez, Victor Haber; Reyero Zaragoza, Inés Upna Orcid; Serrano Lotina, Ana; Campos Ramírez, Leonardo; Santos Dias, Dayana F. dos (Hindawi, 2018)   Artículo / Artikulua  OpenAccess
      The aim of this work was to evaluate the performance of different extruded catalysts containing K2CO3 as active phase and adding conveniently γ-Al2O3 and/or sepiolite and magnetic particles on the biodiesel production from ...
    • A field induced ferromagnetic-like transition below 2.8 K in Li2CuO2: An experimental and theoretical study 

      Ortega Hertogs, Ricardo Upna; Jensen, P. J.; Rao, K. V.; Sapiña, F.; Beltrán, D.; Iqbal, Z.; Cooley, J. C.; Smith, J. L. (AIP Publishing, 1998)   Artículo / Artikulua  OpenAccess
      The low temperature magnetic properties of the Li2CuO2 compound have been investigated by means of superconducting quantum interference device magnetometry. We find in addition to an antiferromagnetic phase below 9.5 K a ...
    • Routes for enhanced magnetism in Ni-Mn-In metamagnetic shape memory alloys 

      López García, Javier Upna; Sánchez-Alarcos Gómez, Vicente Upna Orcid; Recarte Callado, Vicente Upna Orcid; Pérez de Landazábal Berganzo, José Ignacio Upna Orcid; Fabelo, O.; Cesari, Eduard; Rodríguez Velamazán, José Alberto (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      The authors provide in-depth physical insight into the enhancement of the magnetic properties of metamagnetic shape memory alloys produced by thermal treatment and cobalt doping. They use neutron scattering to study the ...
