Fluorescent core-shell nanoparticles and nanocapsules using comb-like macromolecular RAFT agents: synthesis and functionalization thereof

Chloé Grazon, Jutta Rieger, Patricia Beaunier, Rachel Méallet-Renault, Gilles Clavier

Fluorescent nanoparticles and nanocapsules (FNPs) were synthesized via a one-pot RAFT miniemulsion process copolymerizing BODIPY-methacrylate and styrene in water. Ultra-bright sub-100 nm core–shell nanoparticles could be obtained with BODIPY covalently linked in the core, and possessing various…

Effect of postsynthesis preparation procedure on the state of copper in CuBEA zeolites and its catalytic properties in SCR of NO with NH3

Rafal Baran, Frederic Averseng, Dominik Wierzbicki, Karolina Chalupka, Jean-Marc Krafft, Teresa Grzybek, Stanislaw Dzwigaj

Copper-containing BEA zeolites, Cu2.0SiBEA and Cu2.0HAlBEA, with 2 wt % of Cu were prepared by a two-step postsynthesis method and a conventional wet impregnation, respectively. These zeolites were characterized by XRD, DR UV–vis, EPR, FTIR and TPR physicochemical techniques. The incorporation of…

NMR cogwheel phase cycling determination with web tools: Amplitude-modulated z-filter MQMAS sequence

Yannick Millot, Redouane Hajjar, Pascal P. Man

Our recent method based on the use of web tools (XML and XSLT) for constructing cogwheel phase cycles is extended to the selection of two sym. coherence transfer pathways in the case of an amplitude-modulated z-filter MQMAS sequence. For all spins (I=3/2, 5/2, 7/2 and 9/2) and all MQ expts. we…

Influence of Coadsorbed Water and Alcohol Molecules on Isopropyl Alcohol Dehydration on γ-Alumina: Multiscale Modeling of Experimental Kinetic Profiles

Kim Larmier, Andre Nicolle, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Successfully modeling the behavior of catalytic systems at different scales is a matter of importance not only for a fundamental understanding but also for a more rational design of catalysts and a more precise definition of the kinetic laws used as inputs in chemical engineering. We have developed…

Structure and Surface Study of Hydroxyapatite-Based Materials: Experimental and Computational Approaches

Guylène Costentin, Christophe Drouet, Fabrice Salles, Stéphanie Sarda

In addition to designing catalytic materials ever more active and selective, the emergence of new classes of greener catalysts remains very challenging. The apatite family system with hydroxyapatite (HA) structure appears as a good candidate for catalysis due to its eco-compatibility properties,…

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…
