    • Electron Paramagnetic Resonance Study of Copper− Ethylenediamine Complex Ion Intercalated in Bentonite 
      Donoso, José Pedro; Magon, Claudio J.; Lima, José F.; Nascimento, Otaciro R.; Benavente Espinosa, Eglantina; Moreno, Mabel; González Rees, Guillermo (American Chemical Society, 2013)
      This work reports on studies of two-dimensional networks of Cu2+ ions, built by exchanging Na-bentonite with Cu2+ aqueous or with the bis(ethylenediamine) complex, [Cu(C2H4 (NH2))2]2+, at different concentrations of the ...
    • Magnetic resonance study of a vanadium pentoxide gel 
      Nascimento, Otaciro R.; Magon, Claudio J.; Lima, Jose Fernando; Donoso, Jose Pedro; Benavente Espinosa, Eglantina; Paez, Jaime; Lavayen, Vladimir; Santa Ana, María Angélica; González Moraga, Guillermo (2008)
      In this work we report results from continuous-wave (CW) and pulsed electron paramagnetic resonance (EPR) and proton nuclear magnetic resonance (NMR) studies of the vanadium pentoxide xerogel V2O 5:nH2O (n ≈ 1.6). The low ...
