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…

Brake wear (nano)particle characterization and toxicity on airway epithelial cells in vitro

Chloé Puisney, Evdokia K Oikonomou, Sophie Nowak, Alexandre Chevillot, Sandra Casale, Armelle Baeza-Squiban, Jean-François Berret

Particulate air pollution results from different sources, among which those related to road traffic have a significant impact on human health. Combustion-derived particles emitted by thermal engines have been incriminated and are now better controlled. In contrast, non-exhaust emission sources…

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…

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.…

Selective gas phase hydrogenation of nitroarenes over Mo 2 C-supported Au-Pd

Xiaodong Wang, Noémie Perret, Laurent Delannoy, Catherine Louis, Mark A. Keane

We report the first synthesis of Mo2C-supported Au and Au–Pd catalysts (nominal Au/Pd = 10 and 30) obtained from colloidal nanoparticles stabilised by polyvinyl alcohol (PVA). Equivalent Au/Al2O3 and Au–Pd/Al2O3 were prepared and served as benchmarks. Residual PVA was removed by thermal treatment…

Ordered Nanostructures on a Hydroxylated Aluminum Surface through the Self-Assembly of Fatty Acids.

Irma Liascukiene, Nesrine Aissaoui, Svajus J. Asadauskas, Jessem Landoulsi, Jean-François Lambert

We investigate the mechanism of self-assembly of fatty acids (FA) and methyl oleate on an Al oxy-hydroxide surface with a view to deciphering the role and nature of interfacial processes (adsorption, chemical binding, molecular organization, etc.). For this purpose, we focus on parameters related…

Chromium Oxide Species Supported on Silica: A Representative Periodic DFT Model

Hazar Guesmi, Frederik Tielens

The Cr/SiO2 system is investigated using periodic DFT. The model represents the amorphous character of the silica surface and allows the investigation of the effect of hydration on the Cr(VI) monomers. First, the geometry and energetics are discussed and compared with experimental data. The phase…
