Mesoporous silica supported amine and amine-copper complex for CO2 adsorption: Detailed reaction mechanism of hydrophilic character and CO2 retention

Bouhadjar Boukoussa, Aboubakr Hakiki, Nabil Bouazizi, Ana-Paola Beltrao-Nunes, Franck Launay, Alain Pailleret, Françoise Pillier, Abdelkader Bengueddach, Rachida Hamacha, Abdelkrim Azzouz

Mesoporous silica SBA-15 was functionalized with various amines and then doped with copper II cation (Cu2+). The modified materials were tested for the retention of CO2 at room temperature using temperature-programmed desorption (CO2-TPD). Several parameters affecting the CO2 retention capacity (…

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…

Cation redistribution upon dehydration of Na 58 Y faujasite zeolite: a joint neutron diffraction and molecular simulation study

Wilfried Louisfrema, Benjamin Rotenberg, Florence Porcher, Jean-Louis Paillaud, Pascale Massiani, Anne Boutin

Using neutron scattering and Monte Carlo simulation, we investigate the distribution of cations in Na58Y faujasite upon (de)hydration. We introduce a new method for the assignment of cations to specific sites in molecular simulations from their local environment. This allows us to bypass the need…

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…

Facile synthesis of palladium nanowires by a soft templating method

Prem Siril, Anaïs Lehoux, Laurence Ramos, Patricia Beaunier, Hynd Remita

Very long and thin monocrystalline Pd nanowires were synthesized by decomposition using hydrazine vapour treatment of Pd2(DBA)3 confined in the oil phase of a hexagonal mesophase. The mesophase is composed of toluene-swollen tubes, doped with the Pd precursor, stabilized by a monolayer of…
