Non-destructive investigation of fibronectin adsorption on titanium surfaces using PM-RAIRS: effect of surface hydroxylation

Stéphanie Boudesocque, Olivier Dargaud, Lorenzo Stievano, Christophe Méthivier, Jean-Francois Lambert, T. Coradin, Claire-Marie Pradier

Polarisation-modulation reflection-absorption infrared spectroscopy (PM-RAIRS) is a useful non-destructive technique to study semi-quantitatively the adsorption of proteins on metal surfaces. In this work, we employed PM-RAIRS to study the effect of the degree of hydroxylation of the surface of…

Accessibility of Co3O4 nanoparticles patterned in SBA-15

Irène Lopes, Nissrine El Hassan, Gilles Wallez, Cyril Thomas, Anne Davidson

Calibrated crystalline Co3O4 nanoparticles with a narrow size distribution were synthesized inside the pores of SBA-15 silicas and studied by HR-TEM, XRD and Raman spectroscopy. Preferential orientation and size-related structural modifications are revealed. The reactivity for CO oxidation and the…

Gold Nanorods for LSPR Biosensing: Synthesis, Coating by Silica, and Bioanalytical Applications

Vincent Pellas, David Hu, Yacine Mazouzi, Yoan Mimoun, Juliette Blanchard, Clément Guibert, Michèle Salmain, Souhir Boujday

Nanoparticles made of coinage metals are well known to display unique optical properties stemming from the localized surface plasmon resonance (LSPR) phenomenon, allowing their use as transducers in various biosensing configurations. While most of the reports initially dealt with spherical gold…

Phosphate Boosts Nonhydroxyl Radical Species Production upon Air Oxidation of Magnetite and Iron Sulfides at Neutral pH

Guillaume Morin, Frédéric Averseng, Xavier Carrier, Pierre Le Pape, Yishan Du, Yusheng Honge, Elora Bourbon, Giuseppe Sportelli, Tiago A da Silva, Alberto Mezzetti, Camille Baya, Thierry Allard, Jessica Brest, Maryse Rouelle

Heterogeneous Fenton-like reactions using O2 as sole oxidant are gaining interest for designing organic contaminant degradation in soils and groundwaters, since they may provide alternatives to current processes involving strong oxidants. Indeed, several Fe(II)-bearing oxide and sulfide mineral…

Les nanobâtonnets d’or sont des particules plasmoniques présentant des propriétés optiques intéressantes. En particulier, la résonance plasmonique de surface localisée (LSPR) sensible à l’environnement local des particules, permet leur utilisation comme transducteurs de phénomènes d’interactions…, Gold nanorods are plasmonic nanoparticles with interesting optical properties. In particular, the localized surface plasmon resonance (LSPR), sensitive to the local environment of the particles, allows their use as transducers of molecular interaction phenomena.

Cu-modified hydroxy-apatite as catalyst for Glaser–Hay CC homo- coupling reaction of terminal alkynes

Birgit Maaten, Jamal Moussa, Christophe Desmarets, Patrick Gredin, Patricia Beaunier, Tõnis Kanger, Kaia Tõnsuaadu, Didier Villemin, Michel Gruselle

The oxidative Glaser–Hay coupling reaction of terminal alkynes is a very important reaction in organic chemistry to achieve the synthesis of diyne compounds. In general the reaction is performed under homogeneous conditions using Cu(I) or Cu(II) salts in the presence of a reagent such as…

Cation redistribution upon dehydration of Na 58 Y faujasite zeolite: a joint neutron diffraction and molecular simulation study

Wilfried Louisfrema, Benjamin Rotenberg, Florence Porcher, Jean-Louis Paillaud, Pascale Massiani, Anne Boutin

Using neutron scattering and Monte Carlo simulation, we investigate the distribution of cations in Na58Y faujasite upon (de)hydration. We introduce a new method for the assignment of cations to specific sites in molecular simulations from their local environment. This allows us to bypass the need…
