    • Valenzuela, F.; Basualto, C.; Sapag, J.; Romero, J.; Höll, W.; Fonseca, C.; Araneda, C. (Taylor and Francis Inc., 2010)
      A kinetics analysis was conducted for the recovery of zinc (II) ions from a mine drainage sample by a liquid surfactant membrane containing di-(2-ethylhexyl)phosphoric acid as a carrier extractant and Span-80 as the ...
    • Lemus Mondaca, Roberto; Pizarro Oteíza, Sebastián; Pérez Won, Mario; Tabilo Munizaga, Gipsy (Wiley, 2018)
      The focus of this research was based on the application of an osmotic pretreatment (15% NaCl) for drying abalone slices, and it evaluates the influence of hot-air drying temperature (40-80 degrees C) on the product quality. ...
    • Núñez Vergara, Luis; Aldunate, Jorge; Letelier Muñoz, María Eugenia; Bollo Dragnic, Soledad; Repetto Scaramelli, Yolanda; Morello Casté, Antonio; Spencer, P. L.; Squella Serrano, Juan (Elsevier, 1995)
      The cyclic voltammetric (CV) behaviour of nifurtimox was studied. The addition of aprotic solvent (DMF) to nifurtimox in an aqueous citrate buffer system was examined. Qualitatively this results in separation of the initial ...
    • Manzur Saffie, Jorge; Garcia, A. M.; Rivas, V.; Atria Salas, Ana María; Valenzuela, J.; Spodine Spiridonova, Evgenia (Elsevier Ltd, 1997)
      Copper(II) complexes of the ligands (6-methyl-2,2′-dipyridyl)methane (MeDPM) and (6,6′-dimethyl-2,2′-dipyridyl)methane (diMeDPM) were prepared and used as catalysts for the oxidation of 3,5-ditert-butylcatechol to ...
    • González, Juan; Daier, Verónica; García, Silvia; Goodman, Bernard; Atria Salas, Ana María; Sala, Luis; Signorella, Sandra (2004)
      The oxidation of D-galacturonic acid by Cr-VI yields the aldaric acid and Cr-III as final products when a 30-times or higher excess of the uronic acid over Cr-VI is used. The redox reaction involves the formation of ...
    • Barriga González, G.; Aliaga, C.; Chamorro, E.; Olea Azar, Claudio; Norambuena, E.; Porcal, W.; González, M.; Cerecetto, H. (Royal Society of Chemistry, 2020)
      A new series of heteroaryl nitrones were synthesized and evaluated as free radical traps due to the results showed in our previous report. The physicochemical characterization of these new nitrones by electron spin resonance ...
