Crystalline Molybdenum Oxide Thin-Films for Application as Interfacial Layers in Optoelectronic Devices

André Luis Fernandes Cauduro, Roberto dos Reis, Gong Chen, Andreas K. Schmid, Christophe Méthivier, Horst-Günter Rubahn, Léo Bossard-Giannesini, Hervé Cruguel, Nadine Witkowski, Morten Madsen

The ability to control the interfacial properties in metal-oxide thin films through surface defect engineering is vital to fine tune their optoelectronic properties and thus their integration in novel optoelectronic devices. This is exemplified in photovoltaic devices based on organic, inorganic or…

NCI : looking at solute/solvent interactions

Robin Chaudret, C. Narth, Raphaël Lugo, Pascal Mougin, Jean-Charles de Hemptinne, Hervé Toulhoat, J. Contreras-García

Understanding solvation interactions is a key problem for many industrial fields: from pharmaceutical to material sciences. From a quantum mechanical viewpoint, two main difficulties arise: firstly, solvation takes place through weak interactions (hydrogen bonds, van der Waals interactions), which…

Study of calixarenes thin films as chemical sensors for the detection of explosives

P. Montmeat, F. Veignal, C. Methivier, C.M. Pradier, L. Hairault

Calix(n)arenes (n = 4, 6, 8) are used as sensitive coatings for Quartz Crystal Microbalance (QCM)-based chemical sensors, and specially for the detection of dinitrotoluene as a model explosive molecule. Calix(n)arenes complex organic architectures were deposited by spray on gold-coated wafer…

Surface Chirality of Gly-Pro Dipeptide Adsorbed on a Cu(110) Surface

Hervé Cruguel, Christophe Méthivier, Claire-Marie Pradier, Vincent Humblot

The adsorption of chiral Gly-Pro dipeptide on Cu(110) has been characterized by combining in situ polarization modulation infrared reflection absorption spectroscopy (PM-RAIRS) and X-ray photoelectron spectroscopy (XPS). The chemical state of the dipeptide, and its anchoring points and adsorption…

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…
