    • A cheap mesoporous silica from fly ash as an outstanding adsorbent for sulfate in water 
      Castillo, Ximena; Pizarro, Jaime; Ortiz, Claudia; Cid, Héctor; Flores Carrasco, Marcos; De Canck, Els; Van Der Voort, Pascal (Elsevier B.V., 2018)
      This research describes the development of a very cheap mesoporous silica material similar to hexagonal mesoporous silica (HMS) and using a silicate extract as precursor. This precursor is obtained from cheap fly ash by ...
    • Black carbon and other light-absorbing impurities in snow in the Chilean Andes 
      Rowe, Penny M.; Cordero, Raul R.; Warren, Stephen G.; Stewart, Emily; Doherty, Sarah J.; Pankow, Alec; Schrempf, Michael; Casassa, Gino; Carrasco, Jorge; Pizarro, Jaime; MacDonell, Shelley; Damiani, Alessandro; Lambert, Fabrice; Rondanelli, Roberto; Huneeus Lagos, Nicolás; Fe (Nature Publishing Group, 2019)
      Vertical profiles of black carbon (BC) and other light-absorbing impurities were measured in seasonal snow and permanent snowfields in the Chilean Andes during Austral winters 2015 and 2016, at 22 sites between latitudes ...
    • Elemental and Mineralogical Composition of the Western Andean Snow (18°S–41°S) 
      Alfonso, Juan A.; Cordero, Raul R.; Rowe, Penny M.; Neshyba, Steven; Casassa, Gino; Carrasco, Jorge; MacDonell, Shelley; Lambert, Fabrice; Pizarro, Jaime; Fernandoy, Francisco; Feron, Sarah; Damiani, Alessandro; Llanillo, Pedro; Sepulveda, Edgardo; Jorquera, Jose; Garci (Nature Publishing Group, 2019)
      The snowpack is an important source of water for many Andean communities. Because of its importance, elemental and mineralogical composition analysis of the Andean snow is a worthwhile effort. In this study, we conducted ...
    • Mechanisms of Cu2+ biosorption on Lessonia nigrescens dead biomass: Functional groups interactions and ... 
      Cid, Héctor; Flores Carrasco, Marcos; Pizarro, Jaime; Castillo, Ximena; Barros, Daniel; Moreno-Pirajan, Juan; Ortiz, Claudia (Elsevier, 2018-04)
      In this study, the biosorption mechanisms of Cu2+ by dead biomass of the brown seaweed Lessonia nigrescens were characterized, with special emphasis on the chemical environment provided by functional groups, their interactions ...
    • Synthesis and characterization of the first cyrhetrenyl-appended calix[4]arene macrocycle and its application ... 
      Pizarro, Jaime; Flores, Erick; Jimenez, Victor; Maldonado, Tamara; Saitz, Claudio; Vega, Andres; Godoy, Fernando; Segura, Rodrigo (Elsevier B.V., 2019)
      An electrochemical sensor for the determination of Cu(II) in bivalve mollusks using a glassy carbon electrode modified with p-tert-butylcalix [4]arene-bis-cyrhetrenylimine (Cy2(Calix [4])) by square wave anodic stripping ...
