Bimetallic Au-Pd catalysts for selective hydrogenation of butadiene: Influence of the preparation method on catalytic properties

N. El Kolli, L. Delannoy, C. Louis

Supported Au catalysts modified by the addition of small amount of Pd (Au/Pd atomic ratio (10) were prepared according to three different methods, co-deposition-precipitation with urea (DPU), deposition of colloids stabilised either by polyvinyl alcohol (PVA) or by tetrakis (hydroxypropyl)…

Kinetic effects in dehydration, rehydration, and isotopic exchange of bacterial photosynthetic reaction centers

Marco Malferrari, Francesco Francia, Alberto Mezzetti, Giovanni Venturoli, Klaus Gerwert

BACKGROUND:In IR difference spectroscopy of proteins and biological systems, as in many other biophysical techniques, experiments at different hydration levels, and after H/D or H216O/H218O exchange are particularly important, for band assignment and for mechanistic studies. OBJECTIVE:Evaluate the…

Time-resolved infrared spectroscopy in the study of photosynthetic systems.

Alberto Mezzetti, Winfried Leibl

Time-resolved (TR) infrared (IR) spectroscopy in the nanosecond to second timescale has been extensively used, in the last 30 years, in the study of photosynthetic systems. Interesting results have also been obtained at lower time resolution (minutes or even hours). In this review, we first…

Biomineralization Patterns of Intracellular Carbonatogenesis in Cyanobacteria: Molecular Hypotheses

Jinhua Li, Isabel Margaret-Oliver, Nithavong Cam, Thomas Boudier, Marine Blondeau, Eric Leroy, Julie Cosmidis, Feriel Skouri-Panet, Jean-Michel Guigner, Céline Férard, Melanie Poinsot, David Moreira, Purificacion Lopez-Garcia, Corinne Cassier-Chauvat, Franck Chauvat, Karim Benzerara

The recent discovery of intracellular carbonatogenesis in several cyanobacteria species has challenged the traditional view that this process was extracellular and not controlled. However, a detailed analysis of the size distribution, chemical composition and 3-D-arrangement of carbonates in these…

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…

Contributions of photochemistry to bio-based antibacterial polymer materials

Davy-Louis Versace, Louise Breloy, Estelle Palierse, Thibaud Coradin

Surgical site infections constitute a major health concern that may be addressed by conferring antibacterial properties to surgical tools and medical devices via functional coatings. Bio-sourced polymers are particularly well-suited to prepare such coatings as they are usually safe and can exhibit…

Interaction of proteins with chemically controlled surfaces for biosensor development, Interactions des protéines avec des surfaces chimiquement contrôlées pour le développement de bio-senseurs

Victor Lebec

In this work we studied protein adsorption on chemically well-controlled surfaces. The focus is put on linking physico-chemical properties of surfaces (hydrophobicity/charge) to the structural properties of the adsorbed proteins. To this end, alkyl thiols differing by their end group were used to…, Dans ce travail, nous étudions l’adsorption de protéines sur des surfaces chimiquement contrôlées. Le but est d’établir le lien entre les propriétés physico-chimiques de la surface (hydrophobicité /charge) et la structure physique de protéines. Des couches auto-assemblées de thiols ayant des…

HRTEM and STEM-HAADF characterisation of Au-TiO2 and Au-Al2O3 catalysts for a better understanding of the parameters influencing their properties in CO oxidation

L. Delannoy, R.L. Chantry, S. Casale, Z.Y. Li, Yves Borensztein, C. Louis

Gold catalysts supported on titania (Au-TiO2) and alumina (Au-Al2O3) were prepared by deposition- precipitation with urea and then activated before characterisation and reaction in CO oxidation, either by calcination in air at 500 1C or reduction under H2 at 300 1C. Gold nanoparticles with average…
