nPEG-TiO2 Nanoparticles: A facile Route to Elaborate Nanostructured surfaces for Biological Applications.

Jolanda Spadavecchia, Souhir Boujday, Jessem Landoulsi, Claire-Marie Pradier

We report the synthesis of diacid-terminated PEG cubic TiO2 nanocrystals by a simple one-step solvothermal method, and their further use to form nanostructured surfaces for protein immobilization. The relevance and major interest of the so-obtained nanocrystals are the presence of terminal…

Ionic liquid route for the corrosion inhibition of Al alloys: the effect of butylammonium nitrate on the corrosion of AA2024-T6

Abdelmoheiman Zakaria Benbouzid, Oumaïma Gharbi, Najet Sidi-Yakoub, Mai T T Tran, Mireille Turmine, Vincent Vivier

In this work, the effect of an ammonium nitrate ionic liquid on the corrosion susceptibility of an Al-Cu-Mg alloy was investigated. The effect of the nitrate anion and the ammonium cation on the anodic and cathodic kinetics were studied separately using potentiodynamic polarisation testing,…

Les Hydroxyapatites, un système basique atypique modulable par la synthèse : vers l'identification des sites actifs, Hydroxyapatites, an atypical basic system tuneable by synthesis: toward the identification of active sites

Sarah Diallo Garcia

Les Hydroxyapatites (HAp) sont des matériaux basiques dont les propriétés catalytiques atypiques, notamment leur très bonne sélectivité pour la transformation de l'éthanol en n-butanol, sont encore mal rationnalisées. La modulation de leur paramètres de synthèse ainsi leur aptitude à la…, Hydroxyapatites (HAp) are basic materials whose atypical catalytic properties, in particular their high selectivity in n-butanol from ethanol's conversion, are yet to be rationalised. Modulation of their synthesis parameters as well as their ability toward substitution allowed us to use their…

Pseudo-automorphisms with no invariant foliation

Eric Bedford, Serge Cantat, Kyounghee Kim

We construct an example of a birational transformation of a rational threefold for which the first and second dynamical degrees coincide and are $>1$, but which does not preserve any holomorphic (singular) foliation. In particular, this provides a negative answer to a question of Guedj. On our…

Probing the Binding Mechanism of Peptides on a Copper Surface: Multi layer Self-Assembly Promoted by Glutamate Residues

Christophe Methivier, Victor Lebec, Jessem Landoulsi, Claire-Marie Pradier

Short peptides interact strongly with copper surfaces We report here a full characterization on the Interaction of Gly-Pto and the Cu(110) surface: By combining infrared analysis with X-ray photoelectron spectroscopy, two binding centers have been identified: the carboxylate and the amino groups…

Anchoring of Pt(II) Pyridyl Complex to Mesoporous Silica Materials: Enhanced Photoluminescence Emission at Room Temperature and Photooxidation Activity using Molecular Oxygen

Kohsuke Mori, Kentaro Watanabe, Masayoshi Kawashima, Michel Che, Hiromi Yamashita

Chloro(2,2':6',2''-terpyridine)platinum(II) ([Pt(tpy)Cl]Cl) complex was successfully anchored to a series of (3-aminopropyl)trimethoxysilane-modified mesoporous silica materials (MCM-41, SBA-15, and MCM-48). Pt LIII-edge x-ray absorption fine structure (XAFS) measurements reveal…

Amino Acid-Mediated Formation of Zirconia Nanoparticles and their Transparent Dispersions

Amandine Venier, Charlène Brissaud, Benoît Cormary, Erik Camposilvan, Julien Alberici, Denis Chateau, Nora Pousin, Alexandre Chevillot-Biraud, Yannick Millot, Miguel Comesaña-Hermo

We present a straightforward one‐pot hydrothermal method for the synthesis of zirconia nanodispersions, leading to the formation of stable sols. By simply varying the nature of the stabilizer used, one can obtain a large variety of objects with different sizes, shapes and crystallinities. Our…
