Investigation of the interface in silica-encapsulated liposomes by combining solid state NMR and first principles calculations.

Nicolas Folliet, Claire Roiland, Sylvie Bégu, Anne Aubert, Tzonka Mineva, Annick Goursot, Kaliaperumal Selvaraj, Luminita Duma, Frederik Tielens, Francesco Mauri, Guillaume Laurent, Christian Bonhomme, Christel Gervais, Florence Babonneau, Thierry Azaïs

In the context of nanomedicine, liposils (liposomes and silica) have a strong potential for drug storage and release schemes: such materials combine the intrinsic properties of liposome (encapsulation) and silica (increased rigidity, protective coating, pH degradability). In this work, an original…

Polarizable QM/Classical Approaches for the Modeling of Solvation Effects on UV–Vis and Fluorescence Spectra: An Integrated Strategy

Daniele Loco, Natalia Gelfand, Sandro Jurinovich, Stefano Protti, Alberto Mezzetti, Benedetta Mennucci

Hybrid methods combining quantum chemistry and classical models are largely used to describe solvent effects in absorption and emission processes of solvated chromophores. Here we compare three different formulations of these hybrid approaches, using a continuum, an atomistic, or a mixed…

Atomic Scale Observation of the Structural Dynamics of Supported Gold Nanocatalysts under 1,3‐Butadiene by in situ Environmental Transmission Electron Microscopy

Abdallah Nassereddine, Laurent Delannoy, Christian Ricolleau, Catherine Louis, Alloyeau D., Guillaume Wang, Qing Wang, Hazar Guesmi, Jaysen Nelayah

Supported gold catalysts have been reported to exhibit exceptional selectivity towards the desirable product, an alkene, in chemoselective hydrogenation of highly unsaturated alkynes and alkadienes. However, insights on the interactions between the gold nanoparticles and the 1,3‐butadiene…

Reactivity of oxygen species formed upon N2O dissociation over Fe-ZSM-5 zeolite: CO oxidation as a model

Hazar Guesmi, Dorothée Berthomieu, Lioubov Kiwi-Minsker

The oxidative power toward CO of α-oxygen formed upon N2O dissociation over isolated and binuclear Fe/ZSM-5 zeolite is investigated by means of DFT calculations. The two α-sites [Fe-O]+ and [Fe-(μO)-(μOH)-Fe]+ exchanged in ZSM-5 were considered since their activity in the N2O decomposition was…

Effect of vanadium dispersion and of support properties on the catalytic activity of V-containing silicas

Marco Piumetti, Barbara Bonelli, Pascale Massiani, Stanislaw Dzwigaj, Ilenia Rossetti, Sandra Casale, Marco Armandi, Cyril Thomas, Edoardo Garrone

Two V-SBA-15 and V-MCF materials (containing about 2.5 wt.% vanadium) were prepared by direct synthesis and tested as catalysts in the decomposition of the most stable chlorinated-alkane, dichloromethane (a total oxidation reaction) and in the oxidative dehydrogenation (ODH) of propane (a partial…

Catalytic Aspects of Light-Induced Hydrogen Generation in Water with TiO2 and Other Photocatalysts: A Simple and Practical Way Towards a Normalization?

Thomas Maschmeyer, Michel Che

Evaluation is discussed of performance of solid photocatalysts for H2 generation from H2O so that they can be compared in a simple way whether sacrificial soln. is used or not. The addnl. chem. potential present in a sacrificial soln. will be the same regardless of the catalyst system used, so…

Adsorption properties of Fe-containing dealuminated BEA zeolites as revealed by FTIR spectroscopy

Konstantin Hadjiivanov, Elena Ivanova, Radoslav Kefirov, Janusz Janas, Anna Plesniar, Stanislaw Dzwigaj, Michel Che

Adsorption properties of Fe-containing dealuminated BEA zeolites were investigated by FTIR spectroscopy of adsorbed CO and NO. Two Fe-containing SiBEA zeolite samples were prepared by a two-step post-synthesis method: creation of vacant T-atom sites (T = Si, Al) by dealumination of…
