Bimetallic Phosphide (Ni,Cu) 2 P Nanoparticles by Inward Phosphorus Migration and Outward Copper Migration

Anh-Minh Nguyen, Mounib Bahri, Sébastien Dreyfuss, Simona Moldovan, Antoine Miche, Christophe Méthivier, Ovidiu Ersen, Nicolas Mézailles, Sophie Carenco

Bimetallic phosphide nanoparticles are drawing a great interest as a family of nanomaterials. Controlling their fine features such as surface composition, core crystal structure and overall composition is a key to further application. Copper and nickel are particularly interesting first-raw metals…

Co2+ @Mesoporous Silica Monoliths: Tailor‐Made Nanoreactors for Confined Soft Chemistry

Emilie Delahaye, Robinson Moulin, Merwen Aouadi, Virgile Trannoy, Patricia Beaunier, Giulia Fornasieri, Anne Bleuzen

Abstract Mesoporous silica monoliths with various ordered nanostructures containing transition metal M 2+ cations in variable amounts were elaborated and studied. A phase diagram depicting the different phases as a function of the M 2+ salt/tetramethyl orthosilicate (TMOS) and surfactant P123/TMOS…

Hierarchical Self-Assembly of Polyoxometalate-Based Organo Palladium(II) Metallomacrocycles via Electrostatic Interactions

Raphaël Salles, Benjamin Abécassis, Etienne Derat, Dalil Brouri, Aurélie Bernard, Qichun Zhang, Anna Proust, Christophe Desmarets, Guillaume Izzet

The design and synthesis of a supramolecular square composed of polyoxometalate-based hybrid donors and ethylenediamine palladium(II) nodes are reported. The structure of the metallomacrocycle scaffold was inferred by diffusion NMR, small-angle X-ray scattering (SAXS), and molecular modeling. The…

Emergence de biopolymères de complexite contrôlée dans les scénarios d'origine de la vie, Emergence of biopolymers with controlled complexity in an origins of life scenario

Lise Bedoin

La matière vivante se caractérise par la présence de biopolymères non aléatoires dont la fonction biologique dépend de la séquence en monomères. Pour comprendre les origines de la vie, il est essentiel d’expliquer l’émergence de polymères non aléatoires dans un monde où les cellules vivantes n’…, Living matter is characterized by the presence of non-random biopolymers whose biological function depends on the monomer sequence. Thus, a major challenge for the elucidation of the Origins of Life lies in understanding how non-random polypeptides were formed and selected among all of the possible…

Mechanical properties of nanostructured films with an ultralow volume fraction of hard phase

Marion Chenal, Cyril Véchambre, J.-M. Chenal, Laurent Chazeau, Vincent Humblot, Laurent Bouteiller, Costantino Creton, Jutta Rieger

We demonstrate in this paper how polymerization induced self-assembly (PISA) using RAFT can be used to synthesize very asymmetric but monodisperse poly(acrylic acid)-b-poly(n-butyl acrylate) block copolymers, PAA-b-PBA, with a short PAA block and a long PBA block. In the course of the surfactant-…

Structure–Activity Relationship in Manganese Perovskite Oxide Nanocrystals from Molten Salts for Efficient Oxygen Reduction Reaction Electrocatalysis

Francisco Gonell, Carlos M Sánchez-Sánchez, Vincent Vivier, Christophe Méthivier, Christel Laberty-Robert, David Portehault

We report a synthesis pathway in molten salts toward ligand-free nanoparticles of the layered perovskite La0.5Sr1.5MnO4 (l-LSMO) and of the pseudocubic perovskite La0.7Sr0.3MnO3 (pc-LSMO). These particles are readily implemented as oxygen reduction reaction (ORR) electrocatalysts in alkaline…

Supramolecular Self‐Assembly and Organization of Collagen at Solid/Liquid Interface: Effect of Spheroid‐ and Rod‐Shaped TiO 2 Nanocrystals

Mathieu Beauvais, Thomas Degabriel, Nesrine Aissaoui, Vincent Dupres, Elodie Colaço, Karim El Kirat, Rute F Domingos, Dalil Brouri, Claire‐marie Pradier, Jolanda Spadavecchia, Jessem Landoulsi

The adsorption behavior of collagen on solid surfaces is a process that determines the role of this protein to mediate cell–material interaction. Herein, the mechanism of self‐assembly and organization of collagen on a model substrate is investigated in the presence of TiO2 nanoparticles. In…
