Loop-stabilized BAB triblock copolymer morphologies by PISA in water

Pauline Biais, Patricia Beaunier, François Stoffelbach, Jutta Rieger

A straightforward strategy to synthesize in water, loop-stabilized particles via PISA is developed. These particular structures can in theory be obtained through the synthesis of amphiphilic BAB triblock copolymers, starting from a hydrophilic middle block A, which is chain extended in an aqueous…

Advantages of Covalent Immobilization of Metal‐Salophen on Amino‐Functionalized Mesoporous Silica in Terms of Recycling and Catalytic Activity for CO 2 Cycloaddition onto Epoxides

Matthieu Balas, Sébastien Beaudoin, Anna Proust, Franck Launay, Richard Villanneau

NiII and MnIII Schiff base complexes (Salophen-Ni and Salophen-MnCl) bearing a pending carboxylic group were prepared and characterized. Both complexes were grafted onto a mesoporous amino-functionalized SBA-15 silica, by formation of an amide function between the propylamine groups of the support…

2D Monolayer of 1T' Phase of Alloyed WSSe from Colloidal Synthesis

Ashkan Shahmanesh, Davide Romanin, Corentin Dabard, Sang-Soo Chee, Charlie Gréboval, Christophe Methivier, Mathieu G Silly, Julien Chaste, Matthieu Bugnet, Debora Pierucci, Abdelkarim Ouerghi, Matteo Calandra, Emmanuel Lhuillier, Benoit Mahler

We explore the colloidal growth of monolayers of WSSe alloy in their 1T' phase with various Se content. We develop a synthetic procedure leading to reduced aggregation of the flakes. The presence of a narrow band-gap close to the top of the valence band has been evidenced combining…

CO 2 methanation over LDH derived NiMgAl and NiMgAlFe oxides: Improving activity at lower temperatures via an ultrasound-assisted preparation

Michel Obeid, Christophe Poupin, Madona Labaki, Samer Aouad, Sharad Gupta, Haingomalala Lucette Tidahy, Aida Younis, Ferdaous Ben Romdhane, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad, François Delattre

Within the idea to catalyze CO 2 methanation NiMgAl and NiMgAlFe oxides were synthesized by the layered double hydroxide route using co-precipitation and ultrasound-assisted co-precipitation. MgAl and MgAlFe oxides-supported Ni materials prepared by the impregnation method were used as references.…

Salt concentration and pH-dependent adsorption of two polypeptides on planar and divided alumina surfaces; in situ IR investigations.

Claire-Marie Pradier, Vincent Humblot, Lorenzo Stievano, Christophe Méthivier, Jean-François Lambert

The adsorption of proteins is the first process to take place when a solid is immersed in a biological fluid; though not yet thoroughly understood at a molecular level, this process is also known to be strongly influenced by the presence of salt in solution or by pH changes. In the present work,…

Search for confinement effects in mesoporous supports: hydrogenation of o-xylene on Pt /MCM-41

Franck Letellier, Juliette Blanchard, Katia Fajerwerg, Catherine Louis, Michele Breysse, Denis Guillaume, Denis Uzio

The occurrence in meso-porous supports of a confinement effect related to the adsorption strength of a reaction intermediate on a metallic phase dispersed in the meso pores is examd., as well as its effect on the activity and selectivity. A model is proposed in order to det. the catalyst…

Molten Salts‐Driven Discovery of a Polar Mixed‐Anion 3D framework at the nanoscale: Zn4Si2O7Cl2, Charge Transport and Photoelectrocatalytic Water Splitting

Ram Kumar, Yang Song, Anissa Ghoridi, Philippe Boullay, Gwenaelle Rousse, Christel Gervais, Cristina Coelho Diogo, Houria Kabbour, Capucine Sassoye, Patricia Beaunier, Victor Castaing, Bruno Viana, Maria Luisa Ruiz Gonzalez, José Gonzalez Calbet, Christel Laberty-Robert, David Portehault

Mixed-anion compounds widen the chemical space of attainable materials compared to single anionic compounds, but the exploration of their structural diversity is limited by common synthetic paths. Especially, oxychlorides rely mainly on layered structures, which suffer from low stability during…
