Amphiphilic block copolymer nano-fibers via RAFT-mediated polymerization in aqueous dispersed system

Stephanie Boisse, Jutta Rieger, Khaled Belal, Aurelie Di-Cicco, Patricia Beaunier, Min-Hui Li, Bernadette Charleux

Self-assembled block copolymer nanofibers are attractive materials for multiple applications. We propose here a novel, very simple and straightforward method to prepare polymeric nanofibers at high solids contents directly in water. It is based on an aqueous emulsion polymerization process…

Co-grafting of amino-poly(ethylene glycol) and Magainin I on a TiO2 surface: tests of antifouling and antibacterial activities.

Jessie Peyre, V. Humblot, C. Méthivier, J.M. Berjeaud, C.-M. Pradier

An antimicrobial peptide, Magainin I (Mag), was grafted to a titanium oxide surface, via an antiadhesive poly(ethylene glycol) (PEG) cross-linker. The latter plays a 2-fold part, being antiadhesive, and enabling the covalent immobilization of the peptide. The functionalization was characterized at…

Preparation of amorphous silica-aluminas with enhanced acidic properties and spectroscopic identification of their acid sites, Préparation de silice-alumines amorphes avec des propriétés acides améliorées et identification spectroscopique de leurs sites acides

Xiaojing Jin

ASAs with enhanced acidity and a higher fraction of acidic Al were prepared by two experimental strategies. Their textures have been investigated by N2 adsorption–desorption and their acidic properties by FTIR of adsorbed probe molecule (pyridine or CO). Besides, isomerization of 33DMB1 was…, Des silice-alumines (SA) avec des propriétés acides améliorées et une fraction plus élevée d’aluminium acides ont été préparées en utilisant deux stratégies de synthèse. Leurs propriétés texturales ont été étudiées par physisorption de N2 et leurs propriétés acides par suivi FTIR de l’adsorption de…

Tuning the Growth Mode of 3D Silver Nanocrystal Superlattices by Triphenylphosphine

Karima Ouhenia-Ouadahi, Amandine Andrieux-Ledier, Johannes Richardi, Pierre-Antoine Albouy, Patricia Beaunier, Peter Sutter, Eli Sutter, Alexa Courty

Here, we show that the residual presence of reaction products markedly influences the growth mode of 3D superlattices made of silver nanocrystals. The silver nanocrystals (5 or 6 nm in diameter) are synthesized via the reduction of a silver triphenylphosphine complex in the presence of thiols. The…

On an additional promoting role of hydrogen in the H2-assistedC3H6-SCR of NOxon Ag/Al2O3: A lowering of the temperature offormation-decomposition of the organo-NOxintermediates?

Cyril Thomas

tThe addition of minute amounts of H2to the selective catalytic reduction of nitrogen oxides (NOx)by hydrocarbons (HC-SCR) has been shown to promote the reduction of NOxat remarkably lowerreaction temperatures on Ag/Al2O3catalysts. Despite extensive investigations, the origin of this remark-able…

Tuning Model Drug Release and Soft-Tissue Bioadhesion of Polyester Films by Plasma Post-Treatment

Vishal T. Mogal, Chaw Su Yin, Richard O’rorke, Souhir Boujday, Christophe Méthivier, Subbu S. Venkatraman, Terry W. J. Steele

lasma treatments are investigated as a post-production method of tuning drug release and bioadhesion of poly(lactic-co-glycolic acid) (PLGA) thin films. PLGA films were treated under varying conditions by controlling gas flow rate, composition, treatment time, and radio frequency (RF) power. In…

IR Operando Study of the Acetylene Effect on the NO Reduction Mechanism on Pd–Rh/CeO2–ZrO2 Three-Way Catalyst

T. Onfroy, O. Marie

The impact of acetylene on the NO reduction mechanism was investigated on a Pd–Rh/CeO2–ZrO2 catalyst. Temperature Program Reaction revealed that C2H2 has a detrimental effect on NO reduction by both H2 and CO. Stationary regime perturbed by C2H2 pulse at different temperatures showed that surface…
