Going through the wine fining: Intimate dialogue between organics and clays

Pollyana Trigueiro, Silvia Pedetti, Baptiste Rigaud, Sebastien Balme, Jean-Marc Janot, Ieda M G Dos Santos, Régis Gougeon, Maria G Fonseca, Thomas Georgelin, Maguy Jaber

Wine chemistry inspires and challenges with its complexity and intriguing composition. In this context, the composites based on the use of a model protein, a polyphenol of interest and montmorillonite in a model hydroalcoholic solution have been studied. A set of experimental characterization…

BSA and lysozyme adsorption on homoionic montmorillonite: Influence of the interlayer cation

Mathilde Lepoitevin, Maguy Jaber, Régis Guégan, Jean-Marc Janot, Philippe Dejardin, Francois Henn, Sébastien Balme

This study aims to investigate the influence of interlayer cation alkali metal series (Li+, Na+, K+, Rb+, Cs+) and alkali earth metal (Mg2 +, Ca2 +, Ba2 +) on adsorption of model proteins (lysozyme and bovine serum albumin). The localizations of both proteins and their conformational modifications…

TiO2-supported Rh nanoparticles: From green catalyst preparation to application in arene hydrogenation in neat water

Claudie Hubert, Audrey Denicourt-Nowicki, Patricia Beaunier, Alain Roucoux

TiO2-supported Rh(0) nanoparticles were prepd. by an easy method under mild conditions in neat water. They proved to be highly active catalysts for arene hydrogenation in water with TOFs up to 33 333 h-1. [on SciFinder(R)]

Experimental and theoretical evidences of the influence of hydrogen bonding on the catalytic activity of a series of 2-hydroxy substituted quaternary ammonium salts in the styrene oxide/CO2 coupling reaction

Catarina Carvalho Rocha, Thomas Onfroy, Julien Pilmé, Audrey Denicourt-Nowicki, Alain Roucoux, Franck Launay

Among industrial applications of CO2, the formation of cyclic carbonates from epoxides offers relevant chemical potentialities. Here, various N,N-dimethyl-N-cetyl-N-(2-hydroxyethyl)ammonium salts (HEA16X) associated with different counter-anions (X−) have been investigated as catalysts of the…

Investigation of the role of stabilizingagentmolecules in the heterogeneousnucleation of rhodium(0) nanoparticles onto Al-SBA-15 supports

Rita Sassine, E. Bilé-Guyonnet, Thomas Onfroy, Audrey Denicourt-Nowicki, Alain Roucoux, Franck Launay

Interactions of stabilizingagentmolecules (HEA16Cl) with Rh(0) particles and mesoporous aluminosilic supports were studied in rhodium(0) catalysts obtained by heterogeneousnucleation. HEA16Cl/Rh(0) proximity was indirectly demonstrated by monitoring the CO coverage of metal surface using FTIR…

Stochastic Simulation and Single Events Kinetic Modeling: Application to Olefin Oligomerization

Javad Sharouzi, Denis Guillaume, Pierre Rouchon, Patrick da Costa

In order to handle a tractable network for complex reaction systems such as oligomerization, stochastic tools are applied to reduce the reaction mechanism. The particularity of this work is that quantitative single event kinetic modeling constants are used to generate a network which correctly…

Spectroscopies à l'échelle de la molécule individuelle : dynamique de force pour l'interaction d'oligopeptides sur or et diffusion Raman exaltée par effet de pointe sur rotaxanes, Spectroscopy on the scale of the individual molecule: dynamics of strength for the interaction of oligopeptides on gold and distribution Raman excited by state-of-the-art effect on rotaxanes

Marie Steffenhagen

Au-delà de la simple imagerie, les techniques de champ proche permettent sonder des interactions moléculaires de manière contrôlée sur un nombre réduit de molécules, voire une seule. Dans ce sujet, deux techniques de spectroscopie à sonde locale ont été mises à profit. D’une part, la spectroscopie…, Beyond simply imaging, near-field techniques allow to probe and control molecular interactions onto a reduced number of molecules, if not a single one. In this subject, we took advantage of two local-probe spectroscopies. On the one hand, dynamic force spectroscopy (AFM-DFS) was applied to measure…

Caractérisations par microscopie, spectroscopie et électrochimie d'un biofilm à partir d'une eau potable sur acier inoxydable

Jean Gamby, Alain Pailleret, C. Boucher, Claire Marie Pradier, Bernard Tribollet

Nous avons suivi la formation d’un biofilm sur l’acier inoxydable (AISI 316) immergé dans un circuit d’eau potable pour deux températures (20 ◦C et 37 ◦C à pH = 8,25 – 8,5), à l’aide de techniques de caractérisation par spectroscopies : PM-IRAS (infrarouge de surface), XPS (spectroscopie des…, Microscopic, spectroscopic and electrochemical methods to investigate development of potable water biofilms on stainless substrate. We studied biofilm formation on stainless steel occurring in a drinking water distribution system which operated at two different temperature (20 ◦C and 37 ◦C at pH =…

Gold nanoparticle-based localized surface plasmon immunosensor for staphylococcal enterotoxin A (SEA) detection

Maroua Ben Haddada, David Hu, Michèle Salmain, Lu Zhang, Chen Peng, Yi Wang, Bo Liedberg, Souhir Boujday

We describe the engineering of stable gold nanoparticle (AuNP) bioconjugates for the detection of staphylococcal enterotoxin A (SEA) using localized surface plasmon resonance (LSPR). Two types of AuNP bioconjugates were prepared by covalently attaching anti-SEA antibody (Ab) or SEA to AuNPs. This…
