Orientation of a Trametes versicolor laccase on amorphous carbon nitride coated graphite electrodes for improved electroreduction of dioxygen to water

Achraf Blout, Florence Billon, Christophe Calers, Christophe Méthivier, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Amorphous carbon nitride (a-CNx) thin films were used for the first time as electrode materials in the elaboration of biofuel cell cathodes as a consequence of i) the natural presence of amine type functional groups and ii) the ease to generate carboxylic acid groups on their surface with the help…

Piezoelectricimmunosensor for direct and rapiddetection of staphylococcal enterotoxin A (SEA) at the ng level

Michèle Salmain, Mahsa Ghasemi, Souhir Boujday, Jolanda Spadavecchia, Marie-Clarisse Techer, Florence Val, Vincent Le Moigne, M. Gautier, Romain Briandet, Claire-Marie Pradier

A direct, label-free immunosensor was designed for the rapiddetection and quantification of staphylococcal enterotoxin A (SEA) in buffered solutions using quartz crystal microbalance with dissipation (QCM-D) as transduction method. The sensing layer including the anti-SEA antibody was constructed…

Surface-dependent sulfidation and orientation of MoS 2 slabs on alumina-supported model HDS catalysts

Cédric Bara, Anne-Félicie Lamic-Humblot, Emiliano Fonda, Anne-Sophie Gay, Anne-Lise Taleb, Elodie D Devers, Mathieu D Digne, Gerhard D Pirngruber, Xavier Carrier

The constant improvement of hydrotreating (HDT) catalysts, driven by industrial and environmental needs, requires a better understanding of the interactions between the oxide support (mostly alumina) and the MoS2 active phase. Hence, this work addresses the support-dependent genesis of MoS2 on four…

Factors impacting the aggregation/agglomeration and photocatalytic activity of highly crystalline spheroid- and rod-shaped TiO 2 nanoparticles in aqueous solutions

Thomas Degabriel, Elodie Colaço, Rute F Domingos, Karim El Kirat, Dalil Brouri, Sandra Casale, Jessem Landoulsi, Jolanda Spadavecchia

We investigate the characteristics, fate and photocatalytic activity of spheroid- and rod-shaped TiO2 nano-crystals in aqueous solutions to better understand their behaviour in media of biological and environmental interest. For this purpose, the potential of a solvothermal method in synthesizing…

Photocatalytic Hydrogen Evolution Using Ni–Pd/TiO 2 : Correlation of Light Absorption, Charge-Carrier Dynamics, and Quantum Efficiency

Ana Luna, Diana Dragoe, Kunlei Wang, Patricia Beaunier, Ewa Kowalska, Bunsho Ohtani, Daniel Bahena Uribe, Miguel A. Valenzuela, Hynd Remita, Christophe Colbeau-Justin

TiO2 surface modification with bimetallic nano particles (NPs) has demonstrated to be a strategy to enhance the hydrogen generation via photocatalysis and to minimize the use of expensive noble metals. A better understanding of the role of bimetallic NPs is of crucial importance to design efficient…

CO2 valorization using epoxides under mild conditions

Chetna Mohabeer, Lionel Estel, Laurent Bischoff, Vincent Levacher, Marie-Pierre Denieul, Alain Ledoux, Salim Derrouiche

Carbon dioxide is the major greenhouse gas suspected to produce the climatic change. In order to reduce the emissions of CO 2 , several ways have been studied like capture process, geological storage and valorization. Recently one of the most important studies is concentrated on chemical…

Gold nanoparticles confined in lamellar mesophases

W. Abidi, B. Pansu, R. Krishnaswamy, P. Beaunier, H. Remita, M. Impéror-Clerc

A lamellar surfactant mesophase is used as a soft confinement medium for gold nanoparticles that are directly synthesized inside the lamellar mesophase by the radiolytic reduction of a gold salt incorporated into the water medium. By increasing the water layer thickness of the mesophase, spherical…

New Insights into the Structure and Degradation of Alizarin Lake Pigments: Input of the Surface Study Approach

Guanzheng Zhuang, Silvia Pedetti, Yoan Bourlier, Philippe Jonnard, Christophe Méthivier, Philippe Walter, Claire-Marie Pradier, Maguy Jaber

Alizarin (Az) lake is a typical example of madder lake pigments that are widely used in cultural heritages. Previous work focused on the complex formation in solution, theoretical models, and crystallized stoichiometric structures (Az/Al3+ = 1:1 or 2:1). However, the classical recipe for preparing…

Influence of Cu on the catalytic activity of FeBEA zeolites in SCR of NO with NH 3

Paweł Boroń, Lucjan Chmielarz, Stanislaw Dzwigaj

Two series of Fe and/or Cu containing BEA zeolites were prepared by different procedures: two-step postsynthesis method (FexSiBEA, CuxSiBEA and FexCuxSiBEA) and conventional wet impregnation (FexHAlBEA, CuxHAlBEA and FexCuxHAlBEA) (x = 1.0 Fe or Cu wt%). Modification of BEA zeolite resulted in the…

Oxidation of laccase for improved cathode biofuel cells performances

Meihui Zheng, Sophie Griveau, Christine Dupont-Gillain, Michel J Genet, Claude Jolivalt

Graphite rods were modified by substituted aryldiazonium salts allowing subsequent laccase immobilisation and direct electron transfer at the cathode. Two covalent enzyme immobilisation methods were performed with carboxy and amino substituted grafted groups, either via the formation of an amide…
