    • A simple solvothermal synthesis of MFe2O4 (M=Mn, Co and Ni) nanoparticles 

      Yáñez, Susana; Sánchez-Andújar, Manuel; Gómez Aguirre, Lilián Claudia; Mira Pérez, Jorge; Señarís-Rodríguez, M. A.; Castro-García, Socorro (Elsevier, 2009-10)
      [Abstract] Nanoparticles of MFe2O4 (M=Mn, Co and Ni), with diameters ranging from 5 to 10 nm, have been obtained through a solvothermal method. In this synthesis, an alcohol (benzyl alcohol or hexanol) is used as both a ...

    • Apparent colossal dielectric constants in nanoporous Metal Organic Frameworks 

      Sánchez-Andújar, Manuel; Yáñez, Susana; Pato Doldán, Breogán; Gómez Aguirre, Lilián Claudia; Castro-García, Socorro; Señarís-Rodríguez, M. A. (American Chemical Society (ACS), 2012-05-30)
      [Abstract] In this work, we show that the hybrid material Co2(1,4-bdc)2(dabco)•[4DMF•1H2O], shows an apparent colossal dielectric constant at room temperature (r5000 at 300 K for =100 Hz). Nevertheless, such response ...

    • Charge ordering and dielectric properties in the near half-doped Pr0.79Na0.21MnO3 perovskite 

      Sánchez-Andújar, Manuel; Yáñez, Susana; Castro-García, Socorro; Señarís-Rodríguez, M. A. (Elsevier, 2008-06)
      [Abstract] The Pr0.79Na0.21MnO3 perovskite has been prepared in polycrystalline form by a ceramic method. We have carried out its structural characterization by synchrotron X-ray powder diffraction (SXRPD) at room temperature ...

    • Influence of Nutrients and pH on the Efficiency of Vertical Flow Constructed Wetlands Treating Winery Wastewater 

      Sánchez Núñez, Marta; Gonzalo, Omar Gael; Yáñez, Susana; Ruiz, Isabel; Soto, Manuel (Elsevier, 2021-05-04)
      [Abstract] Winery wastewater is characterized by high organic content, low nutrient content and low pH at least during vintage periods. The effect of nutrient shortage and low pH on constructed wetlands (CWs) operation was ...

    • Magnetoelectric behavior in the complex CaMn7O12 perovskite 

      Sánchez-Andújar, Manuel; Yáñez, Susana; Biskup, Nevenko; Castro-García, Socorro; Mira Pérez, Jorge; Rivas Rey, José; Señarís-Rodríguez, M. A. (Elsevier, 2009)
      [Abstract] We report a magnetoelectric effect in the double perovskite CaMn7O12, that shows a complex magnetic behavior below 90 K with two magnetic phases coexisting (one ferrimagnetic and the other modulated). A second ...

    • Near Room Temperature Dielectric Transition in the Perovskite Formate Framework [(CH₃)₂NH₂][Mg(HCOO)₃] 

      Pato Doldán, Breogán; Sánchez-Andújar, Manuel; Gómez Aguirre, Lilián Claudia; Yáñez, Susana; López-Beceiro, Jorge; Gracia-Fernández, Carlos; Haghighirad, A. A.; Ritter, F.; Castro-García, Socorro; Señarís-Rodríguez, M. A. (The Royal Society of Chemistry, 2012-05)
      [Abstract] We report that the hybrid organic–inorganic compound [(CH₃)₂NH₂][Mg(HCOO)₃] shows a marked dielectric transition around Tₜ ∼ 270 K, associated to a structural phase transition from SG R[3 with combining macron]c ...
