Surface functionalization by covalent immobilization of an innovative carvacrol derivative to avoid fungal biofilm formation

Aïcha Gharbi, Thibaut Legigan, Vincent Humblot, Sébastien Papot, Jean-Marc Berjeaud

Carvacrol, an aromatic terpenic compound, known to be antimicrobial was grafted onto gold surfaces via two strategies based on newly-synthesized cross-linkers involving either an ester bond which can be cleaved by microbial esterases, or a covalent ether link. Surface functionalizations were…

Amphiphilic Polyoxometalates for the Controlled Synthesis of Hybrid Polystyrene Particles with Surface Reactivity

Jennifer Lesage de la haye, Jean-Michel Guigner, Eric Marceau, Laurent Ruhlmann, Bernold Hasenknopf, Emmanuel Lacôte, Jutta Rieger

Amphiphilic organo-polyoxometalates (POMs) used in the radical emulsion polymerization of styrene allowed the preparation in aqueous medium of stable 50-100 nm polystyrene-POM composite latexes. Thanks to the presence of a trithiocarbonate group in the POM amphiphile, POMs could be covalently…

Effect of Ca-doping on microstructure and photocatalytic activity of ZnO nanoparticles synthesized by sol gel method

R. Slama, J. El Ghoul, K. Omri, A. Houas, L. El Mir, Franck Launay

We report the synthesis of Zn1−xCaxO nanoparticles prepared by a sol–gel processing technique for x ranging from 0 to 0.05. The structural, morphological and optical properties of the nanoparticles were investigated by X-ray diffraction, transition electron microscopy, UV measurements, and…

Chemical Modifications of Au/SiO2 Template Substrates for Patterned Biofunctional Surfaces

Elisabeth Briand, Vincent Humblot, Jessem Landoulsi, Sarunas Petronis, Claire-Marie Pradier, Bengt Kasemo, Sofia Svedhem

The aim of this work was to create patterned surfaces for localized and specific biochemical recognition. For this purpose, we have developed a protocol for orthogonal and material-selective surface modifications of microfabricated patterned surfaces composed of SiO2 areas (100 mu m diameter)…

Polypyrrole nanostructures modified with mono- and bimetallic nanoparticles for photocatalytic H2 generation

Xiaojiao Yuan, Diana Dragoe, Patricia Beaunier, Daniel Bahena Uribe, Laurence Ramos, Maria Guadalupe Méndez-Medrano, Hynd Remita

Conjugated polymer polypyrrole nanostructures modified with bimetallic (Pt–Ni) nanoparticles are very active for hydrogen generation and a synergetic effect is obtained by alloying Pt with Ni.

Importance of the Nature of the Active Acid/Base Pairs of Hydroxyapatite Involved in the Catalytic Transformation of Ethanol to n ‐Butanol Revealed by Operando DRIFTS

Manel Ben Osman, Jean‐marc Krafft, Cyril Thomas, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Operando DRIFTS is used to identify the nature and the role of the surface sites of hydroxyapatites (HAps) involved in the catalytic transformation of ethanol to n‐butanol. The surface processes occurring upon a first reaction step followed by a step under He flow greatly influence the reactivity…

Ni/CeO2 Nanoparticles Promoted by Yttrium Doping as Catalysts for CO2 Methanation

Valeria La Parola, Chao Sun, Patricia Beaunier, Leonarda F Liotta, Patrick da Costa

Ni (5 wt.%) catalysts over yttrium modified CeO2 oxides synthesized by hydrothermal method were prepared. For comparison Ni was supported over pure CeO2 and Y2O3. Characterizations by N2 adsorption/desorption, XRD, XPS, TEM/HRTEM, H2-TPR, CO2-TPD and TGA were carried out. The catalytic performance…
