    The use of metallic particles has been shown to be an effective, low-cost method for degradation of many contaminating compounds. In this work, we analyze the efficiency of MnAl metallic powders for degrading azo dyes, ...
  • Dealloying of Cu-Mg-Ca alloys 

    Mbarek Wael, Ben; Pineda Soler, Eloi; Escoda, Lluïsa; Suñol Martinez, Juan Jose; Khitouni, Mohamed (Multidisciplinary Digital Publishing Institute (MDPI), 2018-11-08)
    Article
    Open Access
    The chemical dealloying of Cu-Mg-Ca alloys in free corrosion conditions was investigated for different alloy compositions and different leaching solutions. For some of the precursor alloys, a continuous, pure fcc copper ...
