One-Pot Radiolytic Synthesis of Gold Nanorods and Their Optical Properties

Wafa Abidi, P. R. Selvakannan, Yanick Guillet, Isabelle Lampre, Patricia Beaunier, Brigitte Pansu, Bruno Palpant, Hynd Remita

A novel one-pot synthesis method to prepare gold nanorods of different aspect ratios using radiolysis is presented. The gold nanorods are synthesized by radiolytic reduction of Au-III complexes in a micellar solution formed by a mixture of cationic surfactants (cetyltrimethylammonium bromide and…

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…

Improvements in photostability and sensing properties of EuVO₄ nanoparticles by microwave-assisted sol–gel route for detection of H₂ O₂ vapors

Chrystel Ambard, Natacha Duée, Franck Pereira, David Portehault, Christophe Méthivier, Claire-Marie Pradier, Clément Sanchez

The inorganic thin-film fluorescence probe, with the advantages of long life span and high sensitivity, has attracted much attention in explosive detection. The poor ultraviolet absorption and lack of an aromatic ring make peroxide-based explosives very hard to detect. As the signature compound of…

Chemical evolution of organic molecules under Mars-like UV radiation conditions simulated in the laboratory with the MOMIE setup

O. Poch, Patrice Coll, Cyril Szopa, F. Stalport, T. Georgelin, M. Jaber, J.F. Lambert

The search for organic carbon at the surface of Mars, as clues of past habitability or remnants of life, is a major science goal of Mars' exploration. Understanding the chemical evolution of organic molecules under current Martian environmental conditions is essential to support the past,…

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…

Semiconductor quantum dots reveal dipolar coupling from exciton to ligand vibration

T. Noblet, L. Dreesen, S. Boujday, C. Methivier, Bertrand Busson, A. Tadjeddine, Christophe Humbert

Within semiconductor quantum dots (QDs), exciton recombination processes are noteworthy for depending on the nature of surface coordination and nanocrystal/ligand bonding. The influence of the molecular surroundings on QDs optoelectronic properties is therefore intensively studied. Here, from the…

Immobilisation of protein A on SAM's for the elaboration of immunosensors

Elisabeth Briand, Michèle Salmain, Chantal Compere, Claire-Marie Pradier

Binary mixtures of 11-mercaptoundecanoic acid (MUA) and other thiols of various lengths and terminal functions were chemisorbed on gold-coated surfaces via S-Au bonds to form mixed self-assembled monolayers (SAMs). Several values of the mole fraction of MUA in the thiol mixtures were tested and the…

Development of acidic sites in WOx/ZrO2

Thomas Onfroy, Guillaume Clet, Marwan Houalla

Evidence is shown of the appearance of Brønsted acidic sites in WOx/ZrO2 at a given W loading and of a direct correlation between the abundance of ‘strong’ Brønsted acidic sites in these catalysts and propan-2-ol decomposition activity.
