Caractérisations par microscopie, spectroscopie et électrochimie d'un biofilm à partir d'une eau potable sur acier inoxydable

Jean Gamby, Alain Pailleret, C. Boucher, Claire Marie Pradier, Bernard Tribollet

Nous avons suivi la formation d’un biofilm sur l’acier inoxydable (AISI 316) immergé dans un circuit d’eau potable pour deux températures (20 ◦C et 37 ◦C à pH = 8,25 – 8,5), à l’aide de techniques de caractérisation par spectroscopies : PM-IRAS (infrarouge de surface), XPS (spectroscopie des…, Microscopic, spectroscopic and electrochemical methods to investigate development of potable water biofilms on stainless substrate. We studied biofilm formation on stainless steel occurring in a drinking water distribution system which operated at two different temperature (20 ◦C and 37 ◦C at pH =…

Density Functional Theory Modeling and Calculation of NMR Parameters: An ab Initio Study of the Polymorphs of Bulk Glycine

Lorenzo Stievano, Frederik Tielens, Irene Lopes, Nicolas Folliet, Christel Gervais, Dominique Costa, Jean-Francois Lambert

The three forms of glycine in the solid state, α, β, and γ are described and modeled by means of generalized-gradient approxn. (GGA) ab initio calcns. In particular, the location of the protons in each structure is studied. The vibrational frequencies and the NMR chem. shifts of 1H, 13C, and 15N in…

Fluidized bed plasmas reactor for catalyst synthesis and pretreatment. Application for pollution abatement in stationary and mobile sources

Marjorie Foix, Cedric Guyon, Michael Tatoulian, Patrick da Costa

The prepn. of automotive catalysts and com. oxidn. catalysts in stationary sources use a large amt. of noble metal precursors. Moreover, during their prepn. high energy (gas and temp.) is necessary for treatment processes. In order to develop a higher sustainable process, the plasma-assisted…

Steam reforming of alpha-methylnaphthalene as a model tar compound over olivine and olivine supported nickel

Rudy Michel, Agata Lamacz, Andrzej Krzton, Gérald Djéga-Mariadassou, Philippe Burg, Claire Courson, Rene Gruber

At high temperature, biomass steam gasification generates tars and more particularly Polycyclic Aromatic Hydrocarbons (PAHs). To assess the ability of olivine-based catalyst to eliminate the tars by steam reforming, alpha-methylnaphthalene (MNP) was chosen as model compound. The Ni/olivine has…

Potential of electrochemical techniques (macro and microelectrodes) in fronth flotation concentration of sulfide minerals, Potencialidade das técnicas eletroquímicas (macro e microeletrodos) na concentração por flotação de minerais sulfetados

Marina Martins Mennucci, Tatiana Mallet Machado, Vincent Vivier, Hercílio Gomes De Melo, Jean Vicente Ferrari

ABSTRACT The interactions between sulfide minerals and the chemistry of the exposure medium, from the grinding process to the flotation pulp, can be electrochemical and/or galvanic and influence the hydrophobicity of their surfaces, resulting in different levels of recovery. In the literature, most…, RESUMO As interações entre os minerais sulfetados e a química do meio de exposição, desde o processo de moagem dos minérios até a polpa de flotação, podem ser de caráter eletroquímico e/ou de natureza galvânica e influenciam a hidrofobicidade de suas superfícies, resultando em diferentes níveis de…

Mechanical properties of nanostructured films with an ultralow volume fraction of hard phase

Marion Chenal, Cyril Véchambre, J.-M. Chenal, Laurent Chazeau, Vincent Humblot, Laurent Bouteiller, Costantino Creton, Jutta Rieger

We demonstrate in this paper how polymerization induced self-assembly (PISA) using RAFT can be used to synthesize very asymmetric but monodisperse poly(acrylic acid)-b-poly(n-butyl acrylate) block copolymers, PAA-b-PBA, with a short PAA block and a long PBA block. In the course of the surfactant-…

Spatially Controlled Reduction and Growth of Silver in Hollow Gold Nanoshell Particles

Lu Zhang, Peng Chen, Alexis Loiseau, Dalil Brouri, Sandra Casale, Michèle Salmain, Souhir Boujday, Bo Liedberg

Spatially controlled reactions at the nanoscale have attracted increasing interest for fundamental chemistry and for the engineering of novel functional materials. Herein, we demonstrate that pH-triggered reduction of silver ions preferentially occurs at the inner walls of porous and citrate-capped…
