EIS investigation of zinc dissolution in aerated sulfate medium. Part I: bulk zinc

Chantal Cachet, F. Ganne, Georges Maurin, J. Petitjean, Vincent Vivier, Robert Wiart

The kinetics of anodic dissolution and corrosion of zinc are investigated by electrochemical impedance spectroscopy in sulfate medium for various surface preparation conditions and different experimental procedures. A new version of the reaction model, which was established previously, accounts…

Tuning the Growth Mode of 3D Silver Nanocrystal Superlattices by Triphenylphosphine

Karima Ouhenia-Ouadahi, Amandine Andrieux-Ledier, Johannes Richardi, Pierre-Antoine Albouy, Patricia Beaunier, Peter Sutter, Eli Sutter, Alexa Courty

Here, we show that the residual presence of reaction products markedly influences the growth mode of 3D superlattices made of silver nanocrystals. The silver nanocrystals (5 or 6 nm in diameter) are synthesized via the reduction of a silver triphenylphosphine complex in the presence of thiols. The…

Self-Organization and/or Nanocrystallinity of Co Nanocrystals Effects on the Oxidation Process Using High-Energy Electron Beam

Ana Cazacu, Claudio Larosa, Patricia Beaunier, Guillaume Laurent, Paolo Nanni, Liliana Mitoseriu, Isabelle Lisiecki

We report the enhanced stability of Co nanocrystals (NCs) when they are highly ordered at both nanometer and micrometer scales. We show for the first time that both the crystalline structure of Co nanoparticles (NPs) and their 2D hexagonal organization have a significant impact on the oxidation…

Direct Observation of the Surface Topography at High Temperature with SEM

Renaud Podor, X. F Le Goff, Joseph Lautru, H.P. Brau, Mathias Barreau, Xavier Carrier, Jerôme Mendonça, Dorian Nogues, Antoine Candeias

High-temperature scanning electron microscopy allows the direct study of the temperature behavior of materials. Using a newly developed heating stage, tilted images series were recorded at high temperature and 3D images of the sample surface were reconstructed. By combining 3D images recorded at…

Phosphate Boosts Nonhydroxyl Radical Species Production upon Air Oxidation of Magnetite and Iron Sulfides at Neutral pH

Guillaume Morin, Frédéric Averseng, Xavier Carrier, Pierre Le Pape, Yishan Du, Yusheng Honge, Elora Bourbon, Giuseppe Sportelli, Tiago A da Silva, Alberto Mezzetti, Camille Baya, Thierry Allard, Jessica Brest, Maryse Rouelle

Heterogeneous Fenton-like reactions using O2 as sole oxidant are gaining interest for designing organic contaminant degradation in soils and groundwaters, since they may provide alternatives to current processes involving strong oxidants. Indeed, several Fe(II)-bearing oxide and sulfide mineral…

Co-grafting of amino-poly(ethylene glycol) and Magainin I on a TiO2 surface: tests of antifouling and antibacterial activities.

Jessie Peyre, V. Humblot, C. Méthivier, J.M. Berjeaud, C.-M. Pradier

An antimicrobial peptide, Magainin I (Mag), was grafted to a titanium oxide surface, via an antiadhesive poly(ethylene glycol) (PEG) cross-linker. The latter plays a 2-fold part, being antiadhesive, and enabling the covalent immobilization of the peptide. The functionalization was characterized at…
