A combined experimental and theoretical study of the simultaneous occupation of SIa and SI0 sites in fully dehydrated K-LSX

Hazar Guesmi, Pascale Massiani, Habiba Nouali, Jean-Louis Paillaud

In the case of fully potassium exchanged X and LSX faujasites, it was reported from a single crystal X-ray study on zeolite X and preliminary powder X-ray diffraction (PXRD) study on zeolite LSX that K+ ions can be found concomitantly in both sites I and I' with partial or full occupancy of…

Amplified plasmonic detection of DNA hybridization using doxorubicin-capped gold particles

Jolanda Spadavecchia, Ramesh Perumal, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

We show in this article that doxorubicin-modified gold nanoparticles (Au NP-DOX) can be used for the post-amplification of the wavelength shift of localized surface plasmon resonance (LSPR) signals after DNA hybridization events. We take advantage of the intercalation properties of DOX with guanine…

Highly active poly(3-hexylthiophene) nanostructures for photocatalysis under solar light

Dita Floresyona, Fabrice Goubard, Pierre-Henri Aubert, Isabelle Lampre, Jeremie Mathurin, Alexandre Dazzi, Srabanti Ghosh, Patricia Beaunier, Francois Brisset, Samy Remita, Laurence Ramos, Hynd Remita

Conjugated polymer nanostructures have recently emerged as a new class of very active photocatalysts under solar light. Poly(3-hexylthiophene) (P3HT) is one of the commonly used conjugated polymers for photovoltaics applications. P3HT nanostructures synthesized in soft templates provided by…

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…
