Selective uptake of La3+ ions with polyoxometalates-functionalized mesoporous SBA-15: An EXAFS study

Ourania Makrygenni, Faiza Lilia Bentaleb, Dalil Brouri, Anna Proust, Franck Launay, Richard Villanneau

In this work, mesoporous materials based on inorganic/organic polyoxometalate (POMs) hybrids with the ability of further incorporating heterometallic lanthanum cations were designed. On the basis of the La3+ coordination to vacant organophosphonyle derivatives of POMs previously studied, herein…

Silica-coated gold nanorods biofunctionalization for localized surface plasmon resonance (LSPR) biosensing

Vincent Pellas, Fadoua Sallem, Juliette Blanchard, Antoine Miche, Sara Martinez Concheso, Christophe Méthivier, Michèle Salmain, Souhir Boujday

We introduce here the engineering of nanobiosensors designed from gold nanorods coated with an ultrathin layer of silica (AuNR@SiO2) and biofunctionalized with antibodies for the Localized Surface Plasmon Resonance (LSPR) biosensing of proteins. Despite the outstanding properties of AuNRs, their…

Design of photomagnetic ultra-thin films by electrodeposition of switchable cyanide-bridged Fe 4 Co 4 complexes, Conception de films photomagnétiques ultra-minces par électrodéposition de complexes Fe 4 Co 4 pontés au cyanure commutables

Amina Benchohra, Jessem Landoulsi, Niéli Daffé, Christophe Méthivier, Emmanuel Maisonhaute, Laure Fillaud, Jan Dreiser, Michal Studniarek, Marie‐anne Arrio, Yanling Li, Sofia Frida Russi, David Kreher, Rodrigue Lescouëzec

Preparing thin-films of molecular polymetallic materials remains one of the current limitations in the implementation of polymetallic complexes into devices. The hurdle was tackled here using an electrochemical route for depositing the cyanido-bridged polymetallic complex {Tl[Fe II (2-TPhTp)(CN) 3…, La préparation de couches minces de matériaux polymétalliques moléculaires reste l'une des limitations actuelles dans la mise en œuvre de complexes polymétalliques dans des dispositifs. Cet obstacle a été abordé ici en utilisant une voie électrochimique pour déposer le complexe polymétallique…

Synthesis and Characterization of Temperature-Responsive N-Cyanomethylacrylamide-Containing Diblock Copolymer Assemblies in Water

Nicolas Audureau, Fanny Coumes, Clémence Veith, Clément Guibert, Jean-Michel Guigner, François Stoffelbach, Jutta Rieger

We have previously demonstrated that poly(N-cyanomethylacrylamide) (PCMAm) exhibits a typical upper-critical solution temperature (UCST)-type transition, as long as the molar mass of the polymer is limited, which was made possible through the use of reversible addition-fragmentation chain transfer…

Synthesis of texturally biphasic mesoporous carbon-silica composites and carbons

Cristiam F. Santa, Maguy Jaber, Jean L. Guth, Ligia Sierra

We report a new synthesis of texturally biphasic carbon-silica composites and carbons that exhibit high surface areas (up to 1500 m2 g 1), pore volumes (up to 1.9 cm3 g 1) and mesopores (4.6-6.9 nm). The composite materials have ordered mesoporous carbon domains embedded in a disordered mesoporous…

A High-Pressure, High-Temperature Flow Reactor Simulating the Hadean Earth Environment, with Application to the Pressure Dependence of the Cleavage of Avocado Viroid Hammerhead Ribozyme

Kunio Kawamura, Mari Ogawa, Noriko Konagaya, Yoshimi Maruoka, Jean-François Lambert, Louis M. P. Ter-Ovanessian, Jacques Vergne, Guy Hervé, Marie-Christine Maurel

The RNA world hypothesis suggests that chemical networks consisting of functional RNA molecules could have constructed a primitive life-like system leading a first living system. The chemical evolution scenario of RNA molecules should be consistent with the Hadean Earth environment. We have…

Direct AFM force mapping of surface nanoscale organization and protein adsorption on an aluminum substrate

Jessem Landoulsi, V. Dupres

We investigate the nanoscale organization of a superficially hydroxylated Al substrate and its effect on subsequent protein adsorption using atomic force microscopy (AFM). For this purpose we used a mode which allows a direct mapping of a variety of surface properties (adhesion, elasticity,…

UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…
