In Situ Generation of Active Pd Nanoparticles within a Macroreticular Acidic Resin: Efficient Catalyst for the Direct Synthesis of Hydrogen Peroxide

Kohsuke Mori, Akihiro Hanafusa, Michel Che, Hiromi Yamashita

An acidic resin bearing SO3H functional groups within its reticular structure acts as an efficient support for the in situ formation of highly active Pd nanoparticles (NPs) responsible for the direct synthesis of hydrogen peroxide from H2 and O2. Characterization by means of X-ray absorption fine…

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,…

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…

Glutamic Acid Adsorption and Transformations on Silica

Meryem Bouchoucha, Maguy Jaber, Thomas Onfroy, Jean-François Lambert, Xue Baiyi

We report here on the adsorption and deposition of l-glutamic acid (Glu) on an amorphous silica and its subsequent thermal transformations. When adsorbed from aqueous solutions, Glu only has a low affinity for the silica surface but at high concentrations the adsorbed molecules serve as nuclei for…

Influence of Magnesium Substitution on the Basic Properties of Hydroxyapatites

Sarah Diallo-Garcia, Danielle Laurencin, Jean-Marc Krafft, Sandra Casale, Mark E. Smith, Hélène Pernot, Guylène Costentin

Magnesium-substituted hydroxyapatites (HAP) have been prepared to evaluate the influence of cationic substitution on the surface basic properties of HAP. Despite successful introduction of some of the magnesium cations into the HAP structure (as evidenced by XRD, infrared, and Raman), no influence of…

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…
