Defect-related multicolour emissions in ZnO tetrapods: from violet, over green to yellow

Miao Zhang, Frédéric Averseng, Francia Haque, Patrizia Borghetti, Jean-Marc Krafft, Benoît Baptiste, Guylène Costentin, Slavica Stankic

The nature of defects in ZnO smoke was studied at different stages of the materials' history by combining photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopies. In contrast to studies previously reported on ZnO nanopowders, high vacuum conditions (P < 10-5 mbar)…

The antibacterial activity of Magainin I immobilized onto mixed thiols Self-Assembled Monolayers

Vincent Humblot, Jean-Fabrice Yala, Pascal Thebault, Kada Boukerma, Arnaud Héquet, Jean-Marc Berjeaud, Claire-Marie Pradier

An antibacterial peptide, Magainin I, was covalently bound to a mixed 11-mercaptoundecanoïc acid (MUA) and 6-mercaptohexanol (C6OH) (ratio 1:3) Self-Assembled Monolayer (SAM) on gold surfaces. Each step of the surface functionalization was characterized by Polarization Modulation Reflection…

Elaboration, activity and stability of silica-based nitroaromatic sensors

D. Mercier, Franck Pereira, Christophe Méthivier, Pierre Montméat, Lionel Hairault, Claire-Marie Pradier

Functionalized silica-based thin films, modified with hydrophobic groups, were synthesized and used as sensors for nitroaromatic compound (NAC) specific detection. Their performance and behavior, in terms of stability, ageing and regeneration, have been fully characterized by combining chemical…

Adsorption and thermal condensation mechanisms of amino acids on oxide supports : I. Glycine on silica

Ming Meng, Lorenzo Stievano, Jean-François Lambert

Glycine was adsorbed on the surface of a well-defined silica from aqueous solutions of variable concentrations and pHs. The adsorbed molecules were characterized using middle-IR and UV-vis-NIR spectroscopies. Except at the lowestpH(2.0), they were predominantly present on the surface as zwitterions…

Insights into bacteriophage T5 structure from analysis of its morphogenesis genes and protein components.

Yvan Zivanovic, Fabrice Confalonieri, Luc Ponchon, Rudi Lurz, Mohamed Chami, Ali Flayhan, Madalena Renouard, Alexis Huet, Paulette Decottignies, Alan R Davidson, Cécile Breyton, Pascale Boulanger

Bacteriophage T5 represents a large family of lytic Siphoviridae infecting Gram-negative bacteria. The low-resolution structure of T5 showed the T=13 geometry of the capsid and the unusual trimeric organization of the tail tube, and the assembly pathway of the capsid was established. Although major…

Hydrolysis of Ammonia-Borane over Ni/ZIF-8 Nanocatalyst: High Efficiency, Mechanism, and Controlled Hydrogen Release

Changlong Wang, Jimena Tuninetti, Zhao Wang, Chen Zhang, Roberto Ciganda, Lionel Salmon, Sergio Moya, Jaime Ruiz, Didier Astruc

Non-noble metal nanoparticles are notoriously difficult to prepare and stabilize with appropriate,dispersion, which in ttirn severely limits their catalytic functions. Here, using zeolitic imidazolate framework (ZIF-8) as MOF template, catalytically remarkably- efficient, ligand-free first-row late…

Tunable laser interference lithography preparation of plasmonic nanoparticle arrays tailored for SERS

Nestor Gisbert Quilis, Médéric Lequeux, Priyamvada Venugopalan, Imran Khan, Wolfgang Knoll, Souhir Boujday, Marc Lamy de La Chapelle, Jakub Dostalek

The facile preparation of arrays of plasmonic nanoparticles over a square centimeter surface area is reported. The developed method relies on tailored laser interference lithography (LIL) that is combined with dry etching and it offers means for the rapid fabrication of periodic arrays of metallic…
