Investigation of ionic surfactant-selective electrodes by EIS

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

A model of ionic surfactant-selective electrodes with mobile ionic sites is proposed. The steady-state concentrations of the active species are calculated. The electrochemical impedance of the membrane immersed between electrolytic solutions is given. This model is in good agreement with the…

Efficiency of Polyoxometalate-Based Mesoporous Hybrids as Covalently Anchored Catalysts

Faiza Bentaleb, Ourania Makrygenni, Dalil Brouri, Cristina Coelho Diogo, Ahmad Mehdi, Anna Proust, Franck Launay, Richard Villanneau

Polyoxometalate (POM) hybrids have been covalently immobilized through the formation of amide bonds on several types of mesoporous silica. This work allows the comparison of three POM-based mesoporous systems, obtained with three different silica supports in which either the organic functions of…

Characterization of Phosphate Species on Hydrated Anatase TiO2 Surfaces

Frederik Tielens, Christel Gervais, Géraldine Deroy, Maguy Jaber, Lorenzo Stievano, Cristina Coelho Diogo, Jean-Francois Lambert

The adsorption/interaction of KH2PO4 with solvated (100) and (101) TiO2 anatase surfaces is investigated using periodic DFT calculations in combination with GIPAW NMR calculations and experimental IR and solid state 17O, and 31P NMR spectroscopies. A complete and realistic model has been used to…

Nanoscale antiadhesion properties of sophorolipid-coated surfaces against pathogenic bacteria

Claire Valotteau, Niki Baccile, Vincent Humblot, Sophie Roelants, Wim Soetaert, Christian V Stevens, Yves Dufrêne

A current challenge in nanomedicine is to develop innovative strategies to fight infections caused by multiresistant bacterial pathogens. A striking example is antiadhesion therapy, which represents an attractive alternative to antibiotics to prevent and treat biofilm-associated infections on…

Zn-Cu Alloy Nanofoams as Efficient Catalysts for the Reduction of CO 2 to Syngas Mixtures with a Potential-Independent H 2 /CO Ratio

Sarah Lamaison, David Wakerley, David Montero, Gwenaëlle Rousse, Dario Taverna, Domitille Giaume, Dimitri Mercier, Juliette Blanchard, Huan Ngoc Tran, Marc Fontecave, Marc Mougel

Alloying strategies are commonly used to design electrocatalysts that take on properties of their constituent elements. Herein, we explore the use of such a strategy to develop Zn-Cu alloyed electrodes with unique hierarchical porosity and tunable selectivity for CO2 vs. H + reduction. By varying…

High pressures pathway toward boron-based nanostructured solids

Remi Grosjean, Yann Le Godec, Simon Delacroix, Guillaume Gouget, Patricia Beaunier, Ovidiu Ersen, Dris Ihiawakrim, Oleksandr O Kurakevych, Corinne Chanéac, David Portehault

Inorganic nanocomposites made of an inorganic matrix containing nanoparticle inclusions provide materials of advanced mechanical, magnetic, electrical properties and multifunctionality. The range of compounds that can be implemented in nanocomposites is still narrow and new preparation methods are…
