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),…

Surface passivation of aluminum alloy 6061 with gaseous trichlorosilane: A surface investigation

Rickielle Ngongang, Eric Marceau, Xavier Carrier, Claire-Marie Pradier, Christophe Méthivier, Jean-Luc Blanc, Martine Carré

A molecular-scale investigation of the interaction at room temperature between gaseous trichlorosilane (HSiCl3), used as a passivating agent, and surfaces of aluminum alloy AA6061 in a polished or hydroxylated state is conducted. Atomic force microscopy (AFM) and scanning electron microscopy (SEM)…

Confinement effect of Nickel in mesoporous silica-based catalysts for syngas production by reforming of methane with CO2, Effet de confinement du nickel dans des catalyseurs à base de silice mésoporeuse pour la production de gaz de synthèse par reformage du méthane avec le CO2

Marie-Nour Kaydouh

Although economically and environmentally advantageous, the methane dry reforming process using supported nickel based catalysts still faces problems of active phase (a transition metal) sintering and of carbon deposition, which result in catalytic activity loss. This thesis is focused on the study…, Malgré ses avantages économiques et environnementaux, le procédé de reformage à sec du méthane sur des catalyseurs au nickel supporté se heurte encore à des problèmes de frittage de la phase active (un métal de transition) et de dépôt de carbone, ce qui entraîne une diminution de l'activité…

Spiky gold shells on magnetic particles for DNA biosensors

Erin Bedford, Souhir Boujday, Claire-Marie Pradier, Frank Gu

Combined separation and detection of biomolecules has the potential to speed up and improve the sensitivity of disease detection, environmental testing, and biomolecular analysis. In this work, we synthesized magnetic particles coated with spiky nanostructured gold shells and used them to…

Molecular Understanding of the Bulk Composition of Crystalline Nonstoichiometric Hydroxyapatites: Application to the Rationalization of Structure-Reactivity Relationships

Manel Ben Osman, Jean Marc Krafft, Yannick Millot, Frederic Averseng, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Crystalline hydroxyapatite samples (HAps) have been prepared by using the co-precipitation method under various pH conditions, leading to nonstoichiometric solids (1.65 < Ca/P < 1.77). The aim of this study was to rationalize the sensitivity of the catalytic activity of HAps to their bulk…

Heterogeneous catalytic partial oxidation of lower alkanes (C 1 –C 6 ) on mixed metal oxides

Jacques Védrine

This review paper aims at analysing the state of the art for partial oxidation and oxidative dehydrogenation (ODH) reactions of lower alkanes C1–C6 into olefins and oxygenated products (aldehydes, anhydrides, carboxylic acids) on metal oxide catalysts with cations of variable oxidation state, such…

Introduction of Co into the Vacant T-Atom Sites of SiBEA Zeolite as Isolated Mononuclear Co Species

Rafal Baran, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A CoSiBEA zeolite was obtained by a postsynthesis method which consisted of a treatment of tetraethylammonium BEA zeolite with nitric acid in the first step and introduction of Co ions into the vacant T atom sites of the SiBEA zeolite by reaction of aqueous Co(NO3)2 solution with silanol groups.…
