    • Adsorption of thiophene and dibenzothiophene on highly dispersed Cu/ZrO2 adsorbents 
      Baeza, P.; Aguila, G.; Vargas, G.; Ojeda, J.; Araya, P. (Elsevier, 2012)
      The effect of surface area of copper/zirconia adsorbents on the adsorption of thiophene (T) and dibenzothiophene (DBT) was studied. Adsorbents were prepared with different loads of copper (1–6%), using as support zirconias ...
    • Desulfurization by adsorption with copper supported on zirconia 
      Baeza, P.; Aguila, Gonzalo; Gracia, F.; Araya, P. (ELSEVIER, 2008-03-20)
      Copper supported on zirconia was used to separate low thiophene concentration from a mixture of 2000 ppmw of thiophene ill n-octane at room temperature and atmospheric pressure. The results show that the capacity of copper ...
    • Identificación de Hantavirus Andes en Rattus norvegicus 
      Fernández, J.; Villagra, E.; Yung, V.; Tognarelli, J.; Araya, P.; Mora, J.; Cattan Ayala, Pedro; Ramírez, E. (Universidad Austral de Chile, 2008)
      In Chile and Argentina Oligoryzomys longicaudalus has been identified as the main reservoir for Hantavirus Andes. The aim of this work was to report the presence of Hantavirus Andes in Rattus norvegicus, an urban rodent ...
    • Improvement of the thermal stability of hydrous zirconia by post-synthesis treatment with NaOH and NH4OH solutions 
      Aguila, Gonzalo; Guerrero, Sichem; Gracia, F. J.; Araya, P. (ELSEVIER, 2006-05-24)
      The structural stability of a commercial hydrous zirconia and a hydrous zirconia synthesized in our laboratory by the sol-gel method has been improved by a post-synthesis reflux treatment with aqueous NH4OH and NaOH solutions ...
