Self-Assembling of Redox-Active Atrazine Poly(ethylenimine) Conjugates – Interfacial Electrochemical and Spectroscopic Characterization

Zhaohui Chen, Michèle Salmain, Claire-Marie Pradier, Nathalie Fischer-Durand, Alain Pailleret, Féthi Bedioui, Sandrine Zanna

Thin films of polymers tethered with both atrazine haptens and ferrocenyl (Fc) probes were formed on polycrystalline gold electrodes by taking advantage of the facile formation of self-assembled monolayers (SAMs) of thiolates. These films were characterized by polarization modulation Fourier…

Total oxidation of propene over Au/xCeO(2)-Al2O3 catalysts: Influence of the CeO2 loading and the activation treatment

Pandian Lakshmanan, Laurent Delannoy, Vincent Richard, Christophe Methivier, Claude Potvin, Catherine Louis

This study explores the reaction of oxidation of propene (1200 ppm) under excess oxygen (9%) over Au/xCeO(2)/Al2O3 catalysts (x = 1.5, 3, 5, and 10 wt% CeO2) to mimic the conditions of VOC decomposition. The present study reveals the influence of several factors that affect the oxidative…

Optimized immobilization of gold nanoparticles on planar surfaces through alkyldithiols and their use to build 3D biosensors

Anne-Laure Morel, Rose-Marie Volmant, Christophe Methivier, Jean-Marc Krafft, Souhir Boujday, Claire-Marie Pradier

This paper describes a controlled way to immobilize gold nanoparticles on planar gold surfaces and the use of the resulting 3D platform to build up a 3D biosensor. The surface was first functionalized by grafting hexanedithiol, this molecule has 2 thiol end groups, which enables its chemical…

Successive Strong Electrostatic Adsorptions of [RhCl6]3– on Tungstated-Ceria as an Original Approach to Preserve Rh Clusters From Sintering Under High-Temperature Reduction

Jeffrey Miller, Neil Schweitzer, Mimoun Aouine, Philippe Vernoux, Abdelmalik Boufar, Juliette Blanchard, Jean-Marc Krafft, Christophe Méthivier, Céline Sayag, Frédéric Ser, Mickaël Sicard, Cyril Thomas

Supported transition metal materials have been identified as ideal candidates for decades to catalyze various reactions of interest in the fields of hydrocarbon refining, energy and environmental catalysis. As the resources in transition metals on earth are known to be limited, it appears to be of…

Comparison between tungsten carbide and molybdenum carbide for the hydrodenitrogenation of carbazole

Agnieszka Szymanska-Kolasa, Marek Lewandowski, Celine Sayag, Dominique Brodzki, G. Djéga-Mariadassou

The activity of molybdenum and tungsten carbides in hydrodenitrogenation (HDN) of carbazole was studied. Transition metal carbides (Mo2C and W2C) were synthesized using the temperature-programmed reaction of the appropriate oxide precursor (MoO3 and WO3) with the following gas mixture: 10 vol.% CH4…

Room-Temperature Synthesis of Iron-Doped Anatase TiO2 for Lithium-Ion Batteries and Photocatalysis

Christian Andriamiadamanana, C. Laberty-Robert, Moulay Tahar Sougrati, Sandra Casale, Carine Davoisne, Snehangshu Patra, Frédéric Sauvage

Iron-doped nanocrystalline particles of anatase TiO2 have been successfully synthesized using a complete room-temperature synthetic approach, leading to particles of high surface area (280 m2/g) and a narrowed band gap of 2.3 eV. These particles were introduced for photocatalysis under white light…

Elaboration of a reusable immunosensor for the detection of staphylococcal enterotoxin A (SEA) in milk with a quartz crystal microbalance

Michèle Salmain, Mahsa Ghasemi, Souhir Boujday, Claire-Marie Pradier

An immunosensor with quartz crystal microbalance (QCM) detection operating in flow-through mode was set up for assaying staphylococcal enterotoxin A (SEA) in model buffer medium and in milk. This biosensor is label-free and operates in the direct format. Each step of construction of the sensing…

Effect of SAM chain length and binding functions on protein adsorption: β-Lactoglobulin and apo-transferrin on gold.

Erin E. Bedford, Vincent Humblot, Frank X. Gu, Claire-Marie Pradier

Controlled immobilization of proteins is crucial in many applications, including biosensors. Allergen biosensing, for example, requires molecular recognition of suitably immobilized proteins by specific antibodies and sensitive measurement of this interaction. Self-assembled monolayers (SAMs),…
