      Vargas Zamora, José A.; Acuña González, Jenaro; Vásquez, Fiorella; Sibaja Cordero, Jeffrey Alejandro (2016-09)
      Reports on the abundances and on metal concentrations in intertidal estuarine invertebrates from the Eastern Tropical Pacific are rare. Thus, the objectives of this report are to make accessible data on the abundances ...
    • Direct functionalization of Mn12-(methacrylate) clusters on Si(100): surface characterization and electrochemical properties 

      Ledezma Gairaud, Marisol; Moehl, Thomas; Montero Villalobos, Mavis Lili; Pineda Cedeño, Leslie William (2016-09)
      The reaction of H–terminated Si(100) with methacrylate–substituted manganese carboxylate clusters [Mn12O12{CH2C(CH3)COO}16(H2O)4], [Mn12–(methacrylate)] via hydrosilylation afforded Mn12–(methacrylate)−Si(100). The chemically ...
    • Harnessing titanium dioxide surface toward novel functional materials 

      Solera Rojas, José Andrés; Rapp, Christin K.; Rivera Martínez, M. Cinthya; Pineda Cedeño, Leslie William (2015)
      The ever-increasing worldwide energy consumption has led the society to quest for novel and functional materials that can be used in the development of solar fuels to some extent lessen the dependence on fossil fuels. In ...
    • Metals in coastal mollusks of Costa Rica 

      Vargas Zamora, José A.; Acuña González, Jenaro; Gómez Ramírez, Eddy; Molina Delgado, Johan (2015-12)
      The input of contaminants to coastal ecosystems is a global problem on the rise. Data on metal pollution from tropical sites is often lacking and pilot surveys are urgently needed to provide a general framework to estimate ...
