  • 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 ...
  • Degradation of azo dyes by rapidly solidified metallic particles 

    Mbarek Wael, Ben; Pineda Soler, Eloi; Khitouni, Mohamed; Fiol Santalo, Núria; Escoda, Lluïsa; Suñol Martinez, Juan Jose (2015)
    Conference lecture
    Open Access
    Azo compounds are one of the most common families of dyes used in textile and leather treatments. An important step during the treatment of water polluted by these compounds, is the degradation of the compounds by ...
  • High efficiency decolorization of azo dye Reactive Black 5 by Ca-Al particles 

    Mbarek Wael, Ben; Pineda Soler, Eloi; Escoda, Lluïsa; Suñol Martinez, Juan Jose; Khitouni, Mohamed (2017-12-01)
    Article
    Open Access
    This work studies the degradation of azo dye Reactive Black 5 by Ca-Al metallic particles prepared by melt-spinning and ball-milling. The morphology and the phase structure of the metallic powders were characterized and ...
