    • Accumulation of Mg to Diffusive Gradients in Thin Films (DGT) devices: Kinetic and thermodynamic effects of the ionic strength 

      Altier Infantes, Alexandra; Jiménez-Piedrahita, Martín; Rey Castro, Carlos; Cecilia Averós, Joan; Galceran i Nogués, Josep; Puy Llorens, Jaume (American Chemical Society, 2016-09-23)
      Availability of magnesium is a matter of concern due to its role in many environmental and biological processes. Diffusive Gradients in Thin Films (DGT) devices can measure Mg availability in situ. This work shows that Mg ...
    • Extending the use of Diffusive Gradients in Thin Films (DGT) to solutions where competition, saturation, and kinetic effects are not negligible 

      Jiménez-Piedrahita, Martín; Altier Infantes, Alexandra; Cecilia Averós, Joan; Puy Llorens, Jaume; Galceran i Nogués, Josep; Rey Castro, Carlos; Zhang, Hao; Davison, William (American Chemical Society, 2017-06-20)
      DGT (Diffusion Gradients in Thin films) was designed to sample trace metals in situ at their natural concentrations. The setup and the experimental deployment conditions were established to allow interpretation of a linear ...
    • Non-purged voltammetry explored with AGNES 

      Aguilar Camaño, David; Galceran i Nogués, Josep; Companys Ferran, Encarnació; Puy Llorens, Jaume; Parat, C.; Authier, L.; Potin-Gautier, M. (Royal Society of Chemistry, 2013)
      The reduction of oxygen increases pH in the surroundings of an electrode. A theoretical model estimates the steady-state pH profile from the surface of the electrode up to the bulk solution. A very simple formula predicts ...
