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…

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…

Boosting CO2 reforming of methane via the metal-support interaction in mesostructured SBA-16-derived Ni nanoparticles

Chao Sun, Paulina Summa, Ye Wang, Katarzyna Świrk, Albert Miró I Rovira, Sandra Casale, Konrad Świerczek, Changwei Hu, Magnus Rønning, Patrick da Costa

High surface area and porosity SBA-16 was synthesized and used as support for Ni nanoparticles using three methods including wet impregnation, citric acid-assisted impregnation, and ammonia evaporation. All the studied samples showed high activity in the CO2 reforming of methane reaction, however,…

A new route for preparing nanoporous Cu–Zn–Ni–Co alloy by electrodeposition and dealloying: Application as electrocatalysts for water reduction

Yuelin Xie, Antoine Miche, Vincent Vivier, Mireille Turmine

<div><p>Nanoporous Cu-Zn-Ni-Co alloys have been prepared on Cu foils by a two-step electrodeposition mechanism in ethylammonium nitrate (EAN), a protic ionic liquid, and ethaline, a deep eutectic solvent (DES). A porous alloy was then produced using a dealloying step. The…

Bifunctional Polyoxometalates for Planar Gold Surface Nanostructuration and Protein Immobilization

Dimitri Mercier, Souhir Boujday, Cyrine Annabi, Richard Villanneau, Claire-Marie Pradier, Anna Proust

Surface nanostructuration was successfully achieved by binding the polyoxometalate (POM) (NBu4)3[PW11O39{(SiC6H4NH2)2O}] covalently onto planar gold surfaces. To do so, POMs functionalized with two terminal amino groups were synthesized and reacted with a mercaptoundecanoic acid self-assembled…

The genesis of a heterogeneous catalyst: in situ observation of a transition metal complex adsorbing onto an oxide surface in solution

Antoine Hervier, Juliette Blanchard, Guylène Costentin, John R. Regalbuto, Catherine Louis, Souhir Boujday

Understanding the interactions between metal complexes and oxide surfaces is crucial to the synthesis of supported metal catalysts. Recently developed in situ techniques have made it possible to closely characterize the solid/liquid interface. For the first time, the adsorption of platinum…

Gold Nanorods for LSPR Biosensing: Synthesis, Coating by Silica, and Bioanalytical Applications

Vincent Pellas, David Hu, Yacine Mazouzi, Yoan Mimoun, Juliette Blanchard, Clément Guibert, Michèle Salmain, Souhir Boujday

Nanoparticles made of coinage metals are well known to display unique optical properties stemming from the localized surface plasmon resonance (LSPR) phenomenon, allowing their use as transducers in various biosensing configurations. While most of the reports initially dealt with spherical gold…

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…

Probing the Orientation of β-Lactoglobulin on Gold Surfaces Modified by Alkyl Thiol Self-Assembled Monolayers

Victor Lebec, Jessem Landoulsi, Souhir Boujday, C. Poleunis, Claire-Marie Pradier, A. Delcorte

The adsorption of a globular protein on chemically well controlled surfaces was investigated in order to correlate its orientation to the surface properties. To this end, three different alkyl thiols, differing by their end group (−COOH, −CH3, and −NH2), were used to build up self-assembled…

Photoelectrochemical properties of nanocrystalline ZnS discrete versus continuous coating of ZnO nanorods prepared by electrodeposition

A. Brayek, S. Chaguetmi, M. Ghoul, I. Ben Assaker, A. Souissi, L. Mouton, P. Beaunier, S. Nowak, F. Mammeri, R. Chtourou, S. Ammar

We developed nanostructured photoanodes for photoelectrochemical (PEC) water splitting and hydrogen generation. They are based on ZnO nanorods electrodeposited on conductive ITO glass on which ZnO@ZnS heterojunctions were formed using two different approaches. In the first case, the ZnO nanorods…
