    • Antibacterial activity against Staphylococcus aureus of chitosan/chondroitin sulfate nanocomplex aerogels ... 
      Angélica Gómez, María; Marcela Bonilla, Jennifer; Alejandra Coronel, María; Martínez, Jonathan; Moran Trujillo, Luis; Orellana, Sandra L.; Vidal, Alejandra; Giacaman, Annesi; Morales, Carlos; Torres Gallegos, Cesar; Concha, Miguel; Oyarzún Ampuero, Felipe; Godoy, Patricio; Lisoni, Judit G.; Henríquez Baez, Carla; Bustos, Carlos; Moreno Villoslada, Ignacio (Walter de Gruyter GMBH, 2018-04)
      The antibacterial activity against Staphylococcus aureus of aerogels fabricated from colloidal suspensions of chitosan/chondroitin sulfate nanocomplexes is analyzed. Upon freeze-drying the colloidal suspensions, the aerogels ...
    • Chitosan/chondroitin sulfate aerogels with high polymeric electroneutralization degree: formation and ... 
      Orellana, Sandra L.; Giacaman, Annesi; Vidal, Alejandra; Morales, Carlos; Oyarzún Ampuero, Felipe; Lisoni, Judit G.; Henríquez Baez, Carla; Moran Trujillo, Luis; Concha Nordemann, Miguel; Moreno Villoslada, Ignacio (Walter de Gruyter GMBH, 2018-04)
      The formation of ultralight, highly porous solid materials (porosity higher than 99 %) containing equivalent molar amounts of chitosan (CS) and chondroitin sulfate (ChS) is presented. First, we show protocols to produce ...
    • Exploring new hydrated delta type vanadium oxides for lithium intercalation 
      Orive Gómez De Segura, Joseba; Fernández de Luis, Roberto; Larrea, Edurne S.; Martínez Amesti, Ana; Altomare, Angela; Rizzi, Rosanna; Lezama, Luis; Arriortua, María I.; Gómez Cámer, Juan Luis; Jauregui, María; Casas Cabanas, Montse; Lisoni, Judit (Royal Society of Chemistry, 2020)
      Three hydrated double layered vanadium oxides, namely Na(0.35)V(2)O(5)0.8(H2O), K-0.36(H3O)(0.15)V2O5 and (NH4)(0.37)V(2)O(5)0.15(H2O), were obtained by using mild hydrothermal conditions. Their delta type structural ...
    • Influence of the oxygen consumption on the crystalline structure of titanium oxides thin films prepared by ... 
      Villarroel, Roberto; Espinoza González, Rodrigo; Lisoni, Judit; González Moraga, Guillermo (Elsevier, 2018-08)
      In the present work, a simple route to control the growth of different crystalline titanium oxides thin films prepared by reactive sputtering is reported. Using the film pumping speed, the oxygen consumption or "oxygen ...
    • Surface roughness and surface-induced resistivity of gold films on mica: Application of quantitative scanning ... 
      Munoz, Raúl C.; Vidal, Guillermo; Mulsow, Marcelo; Lisoni, Judit G.; Arenas, Claudio; Concha, Andres; Mora, Fernando; Espejo, Roberto; Kremer, Germán; Moraga, Luis (2000)
      We report measurements of the resistivity (Formula presented) of a gold film 70 nm thick deposited on mica preheated to 300 °C in UHV, performed between 4 and 300 K, and measurements of the surface topography of the same ...
