One-pot synthesis of a new generation of hybrid bisphosphonate polyoxometalate gold nanoparticles as antibiofilm agents

S. Tomane, E. López-Maya, S. Boujday, V. Humblot, J. Marrot, N. Rabasso, J. Castells-Gil, C. Sicard, Anne Dolbecq, P. Mialane, A Vallée

A reduced polyoxovanadate functionalized with bisphosphonate molecules was synthesized and used to prepare in one step hybrid organic-inorganic polyoxometalate decorated gold nanoparticles. These new composites were shown to strongly inhibit P. aeruginosa and S. epidermidis biofilms growth, the…

Homogeneous and Heterogeneous Catalysis for the Synthesis of Cyclic and Polymeric Carbonates from CO2 and Epoxides: A Mechanistic Overview

Guillaume Laugel, Catarina Rocha Carvalho, Pascale Massiani, Thomas Onfroy, Franck Launay

The utilization of CO2 for the production of useful chemicals is nowadays considered as a promising way to contribute to the reduction of greenhouse gases in the atmosphere, while valorizing at the same time this widely available resource. The synthesis of cyclic carbonates and polycarbonates via…

Inorganic Phosphate and Nucleotides on Silica Surface: Condensation, Dismutation, and Phosphorylation

Thomas Georgelin, Maguy Jaber, Thomas Onfroy, Aaron-Albert Hargrove, France Costa-Torro, Jean-François Lambert

We explore the reactivity of inorganic monophosphate ions (Pi) and 5′-adenosine monophosphate (AMP), adsorbed onto amorphous silica separately or together. This question has relevance for prebiotic chemistry scenarios and, more generally, for biomedical applications involving biomolecule adsorption…

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…

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…

Incorporation of Mn into the vacant T-atom sites of a BEA zeolite as isolated, mononuclear Mn: FTIR, XPS, EPR and DR UV-Vis studies

R. Baran, L. Valentin, Stanislaw Dzwigaj

A MnSiBEA zeolite has been prepared via a two-step postsynthesis procedure which consisted, in the first step, of the treatment of a tetraethylammonium BEA zeolite with nitric acid for the formation of vacant T-atom sites and then, in the second step, of the incorporation of Mn ions into the…

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,…
