Electrochemical and spectroscopic evidences of corrosion inhibition of bronze by a triazole derivative

Ahmed Dermaj, Najat Hajjaji, Suzanne Joiret, Kamal Rahmouni, Abdellah Srhiri, Hisasi Takenouti, Vincent Vivier

The electrochemical behavior of the bronze (Cu–8Sn in wt%) was investigated in 3% NaCl aqueous solution, in presence and in absence of a corrosion inhibitor, the 3-phenyl-1,2,4-triazole-5-thione (PTS). The inhibiting effect of the PTS was evidenced for concentrations higher than 1 mM for the…

Control of the anisotropic shape of cobalt nanorods in the liquid phase: from experiment to theory… and back

Kahina Aït Atmane, Carine Michel, Jean-Yves Piquemal, Philippe Sautet, Patricia Beaunier, Marion Giraud, Mickaël Sicard, Sophie Nowak, Rémi Losno, G. Viau

The polyol process is one of the few methods allowing the preparation of metal nanoparticles in solution. Hexagonal close packed monocrystalline Co nanorods are easily obtained in basic 1,2-butanediol at 448 K after a few minutes using a Co(II) dicarboxylate precursor. By using a combined…

Des matériaux verts biodégradables à base de Montmorillonite et de cystéine ont été préparés dans le but de co-adsorber des cations de métaux lourds et des polluants émergeants en combinant l’expérience et la théorie (calculs DFT). Les analyses thermiques différentielles ont permis d’estimer le…, Layered silicates like smectites are important soil components. Many works have been devoted to functionalize these materials in order to increase their chelating properties which may help retain heavy metals. It is well known that Cd2+, Hg2+, Pb2+, Co2+ and Zn2+ forms stable complexes with sulfur-…
