    • An easy one-pot solvothermal synthesis of poorly crystalline solid ReS2/C microspheres 
      Aliaga, Juan Antonio; Araya, Juan Francisco; Lozano, Harold; Benavente Espinosa, Eglantina; Alonso Núñez, Gabriel; González Moraga, Guillermo (Elsevier, 2015)
      Dense microspheres consisting of poorly crystalline ReS2 embedded in carbon were synthesized with a high yield via a facile one-pot solvothermal route, by reacting dirhenium decacarbonyl, elemental sulfur and an aromatic ...
    • Electrical conductivity and lithium diffusion in molybdenum disulfide intercalated with poly(ethylene oxide) 
      González Moraga, Guillermo; Santa Ana, María Angélica; Benavente Espinosa, Eglantina; Donoso, J. P.; Bonagamba, T. J.; Mello, N. C.; Panepucci, H. (Elsevier, 1996)
      Electrical conductivity and lithium diffusion coefficients of nanocomposites prepared by intercalation of molybdenum disulfide with poly(ethylene oxide), Li0.1,MoS2(PEO)γ, are informed. The products show a semiconductor ...
    • 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 ...
    • Hybrid chitosan-mercaptopropyltrimethoxysilane films with Ag and Au nanoparticles: Synthesis and properties 
      Fuentes, S.; Vera, V.; Rivera, F.; Moreno, M.; Benavente Espinosa, Eglantina; González Moraga, Guillermo (2012)
      Flexible and transparent polymer complexes prepared by blending chitosan (CS) with about 1 M of oligo-mercaptopropilsiloxane were functionalized by incorporating silver or gold nanoparticles in a concentration range of ...
    • A hybrid organic-inorganic layered TiO2 based nanocomposite for sunlight photocatalysis 
      Benavente Espinosa, Eglantina; Maldonado, Carlos; Devis, Sindy; Díaz, Leslie; Lozano, Harold; Sotomayor Torres, Clivia; González Moraga, Guillermo (The Royal Society of Chemistry, 2016)
      A novel hybrid nanocomposite constituted of single TiO2 nanosheets sandwiched between stearic acid self-assembled monolayers was synthesized and tested in the photodegradation of methylene blue under sunlight. The product ...
    • Intercalation chemistry of molybdenum disulfide 
      Benavente Espinosa, Eglantina; Santa Ana, María Angélica; Mendizábal Emaldía, Fernando; González Moraga, Guillermo (2002)
      Most relevant features of the fundamental and applied chemistry of MoS2 are reviewed highlighting the importance of the layered nature of the solid on the optical and catalytic properties of the compounds. Experimental and ...
    • Lithium chemical diffusion coefficients in poly(ethylene oxide)-molybdenum sulfide nanocomposites 
      González Moraga, Guillermo; Santa Ana, María Angélica; Benavente Espinosa, Eglantina (Elsevier Ltd, 1997)
      The intercalation of poly(ethylene oxide) (PEO) in molybdenum sulfide (MoS2) forms the nanocomposites LixMoS2(PEO)0.5 and LixMoS2(PEO)1.0. The lithium ion diffusivity in PEO-containing phases, which depends on both PEO and ...
    • Mixed conductivity and lithium diffusion in poly(ethylene oxide) molybdenum disulfide nanocomposites 
      González Moraga, Guillermo; Santa Ana Villarroel, María Angélica; Benavente Espinosa, Eglantina (Elsevier, 1998)
      The electrical conductivity, the lithium diffusion, and the diffusion activation thermodynamics of the nanocomposites arising from the co-intercalation of lithium and poly(ethylene oxide) in molybdenum disulfide, ...
    • Redox potentials and diffusion of lithium in lamellar compounds 
      Santa Ana, María Angélica; Benavente Espinosa, Eglantina; González Moraga, Guillermo (Taylor and Francis Ltd., 2001)
      Thermodynamic and dynamic properties of intercalation products of lithium into MoS2 are strongly determined by the coordination of lithium in the interlaminar spaces. Lithium redox potentials as well as lithium diffusion ...
