Tunable laser interference lithography preparation of plasmonic nanoparticle arrays tailored for SERS

Nestor Gisbert Quilis, Médéric Lequeux, Priyamvada Venugopalan, Imran Khan, Wolfgang Knoll, Souhir Boujday, Marc Lamy de La Chapelle, Jakub Dostalek

The facile preparation of arrays of plasmonic nanoparticles over a square centimeter surface area is reported. The developed method relies on tailored laser interference lithography (LIL) that is combined with dry etching and it offers means for the rapid fabrication of periodic arrays of metallic…

NO2 disproportionation for the IR characterisation of basic zeolites

Olivier Marie, Nicolas Malicki, Catherine Pommier, Pascale Massiani, Ann Vos, Robert Schoonheydt, Paul Geerlings, Carlos Henriquese, Frédéric Thibault-Starzyk

NO2 disproportionation on alkaline zeolites is used to generate nitrosonium (NO+) and nitrate ions on the surface, and the infrared vibrations observed are very sensitive to the cation chemical hardness and to the basicity of zeolitic oxygen atoms.side pockets of acidic mordenite. We describe here…

N-Methylephedrium Salts as Chiral Surfactants for Asymmetric Hydrogenation in Neat Water with Rhodium(0) Nanocatalysts

Elodie Guyonnet Bile, Audrey Denicourt-Nowicki, Rita Sassine, Patricia Beaunier, Franck Launay, Alain Roucoux

Synthesis of a water-sol. family of optically active N-methylephedrium salts NMeEph12X I [X = Br, HCO3, (S)-lactate] that can be used as efficient protective agents of metallic nanoparticles in neat water was described. The resulting materials were evaluated in the asym. hydrogenation of…

Optimized immobilization of gold nanoparticles on planar surfaces through alkyldithiols and their use to build 3D biosensors

Anne-Laure Morel, Rose-Marie Volmant, Christophe Methivier, Jean-Marc Krafft, Souhir Boujday, Claire-Marie Pradier

This paper describes a controlled way to immobilize gold nanoparticles on planar gold surfaces and the use of the resulting 3D platform to build up a 3D biosensor. The surface was first functionalized by grafting hexanedithiol, this molecule has 2 thiol end groups, which enables its chemical…

Total oxidation of propene over Au/xCeO(2)-Al2O3 catalysts: Influence of the CeO2 loading and the activation treatment

Pandian Lakshmanan, Laurent Delannoy, Vincent Richard, Christophe Methivier, Claude Potvin, Catherine Louis

This study explores the reaction of oxidation of propene (1200 ppm) under excess oxygen (9%) over Au/xCeO(2)/Al2O3 catalysts (x = 1.5, 3, 5, and 10 wt% CeO2) to mimic the conditions of VOC decomposition. The present study reveals the influence of several factors that affect the oxidative…

A New Antibacterial N -Halamine Coating Based on Polydopamine

Nadia Nazi, Vincent Humblot, Catherine Debiemme

To prevent the formation of biofilms on material surfaces, the latter must have antibacterial properties. The aim of this study is to investigate the synthesis and the antibacterial effect of a new N-halamine coating based on polydopamine (PDA). The benefits of this coating are multiple, notably…

Elaboration, activity and stability of silica-based nitroaromatic sensors

D. Mercier, Franck Pereira, Christophe Méthivier, Pierre Montméat, Lionel Hairault, Claire-Marie Pradier

Functionalized silica-based thin films, modified with hydrophobic groups, were synthesized and used as sensors for nitroaromatic compound (NAC) specific detection. Their performance and behavior, in terms of stability, ageing and regeneration, have been fully characterized by combining chemical…

Real-time monitoring of the uniform corrosion rate of aluminum using picosecond acoustic method

Cyrine Lamloum, Oumaïma Gharbi, Laurent Belliard, Vincent Vivier, Kieu Ngo

This paper introduces a novel operando measurement technique to monitor the degradation rate of aluminum (a thin layer of Al deposited on a sapphire substrate), first in a commercial aluminum etching solution, and then in a sodium chloride solution using a pumpprobe spectroscopy technique. By…

EIS measurements in molecular electronics

Meiling Su, Kieu Ngo, Jean-Christophe Lacroix, Mireille Turmine, Vincent Vivier

Although electrochemical impedance spectroscopy (EIS) has already demonstrated its reliability in electrochemistry and organic semiconductors as a tool for tracking charge-carrier transport, its potential in molecular electronics has not yet been fully realized. In this emerging field, where DC-…
