    • Anthocyanin composition in aged Chilean Cabernet Sauvignon red wines 
      Aguirre, María J.; Isaacs, Mauricio; Matsuhiro, Betty; Mendoza, Leonora; Santos, Leonardo S.; Torres, Simonet (2011)
      Anthocyanins in aged Cabernet Sauvignon red wines were studied by HPLC-MS. The major anthocyanin in 6, 7, and 8 year old red wine extracts was the dimer vitisin A produced by condensation of malvidin-3-O-glucoside mediated ...
    • Electrochemical coating of [trans-L14CoIIICNFe II(CN)5]Na on ITO/Au electrode and its electrocatalytic ... 
      Cáceres, César; Martínez, Manuel; Rodríguez, Carlos; Dreyse, Paulina; Ortega, Victoria; Isaacs, Mauricio (Elsevier B.V., 2014)
      The preparation of an ITO (Indium Tin Oxide) modified electrode with a mixed valence CoIII/FeII complex is described. The ITO electrode was initially modified with Au nanoparticles by dip coating in order to obtain and ...
    • Electrochemical conversion of carbon dioxide into CHO- containing compounds on multimetallic porphyrins 
      Calfuman, Karla; Honores, Jessica; Guzmán, Diego; Ohlbaum, Macarena; Armijo, Francisco; Río, Rodrigo del; Isaacs, Mauricio (Wiley, 2017)
      This work describes the electrochemical reduction of carbon dioxide in aqueous solution mediated by tetraruthenated metal-loporphyrins (TRP; Co(II) and Zn(II)) in Nafion (Nf) and polyvinyl chloride (PVC) as a support. The ...
    • Electrochemical Properties of a Conducting Film Derived from Iron(II) Tris(diaminopolypyridyl) Complex in ... 
      García, Camilo; Domínguez, Cristian; Aliaga, Alvaro; Matsuhiro, Betty; Mendoza, Leonora; Aguirre, María J.; Isaacs, Mauricio (2011)
      A new conducting film derived from the complex [Fe (diaphen)3]2+, (diaphen=5,6-diamino-1,10-phenanthroline) was electropolymerized by cyclic voltammetry onto a glassy carbon electrode. Poly-[FeII (diaphen)3] was studied ...
    • Electrochemical reduction of nitrite at poly-[Ru(5-NO2-phen) 2Cl] tetrapyridylporphyrin glassy carbon ... 
      Dreyse, Paulina; Isaacs, Mauricio; Calfumán, Karla; Cáceres, César; Aliaga, Alvaro; Aguirre, María Jesús; Villagra, Diego (2011)
      This work describes the preparation of modified electrodes with Poly-tetraruthenated porphyrin. Also, a detailed Raman and electrochemical characterization of these surfaces is shown. Glassy carbon electrodes were modified ...
    • Electrochemical reduction of nitrite at polymeric Co (II)-tetra-3-amino- phenylporphyrin modified electrode 
      San Martín, Cristian; Dreyse, Paulina; García, Camilo; Calfumán, Karla; Villagra, Diego; Isaacs, Mauricio (Sociedad Chilena de Quimica, 2007)
      This paper describes the electrochemical reduction of nitrite ion in basic media 0.2M KHC03, with glassy carbon or ITO electrodes modified with a conducting polymer derived from Co(II)tetra-3-aminophenyl-porphyrin. Cyclic ...
    • On the mechanism of CO2 electro-cycloaddition to propylene oxides 
      Gallardo Fuentes, Sebastián; Contreras Ramos, Renato; Isaacs, Mauricio; Honores, Jessica; Quezada, Diego; Landaeta, Esteban; Ormazábal Toledo, Rodrigo (Elsevier, 2016)
      We herein present a systematic study on the mechanism of CO2 electro-cycloaddition to propylene oxide, using both experimental and theoretical procedures. The study considers the analysis of mild and sustainable conditions ...
