Effect of pH on the incorporation of acrylic acid units in the core of polymer nanoparticles prepared by PISA and on their morphology

Clément Debrie, Noémie Coudert, Jean-Michel Guigner, Fanny Coumes, Clément Guibert, Simon Harrisson, François Stoffelbach, Olivier Colombani, Jutta Rieger

Polymerization-induced self-assembly (PISA) is a polymerization process in which amphiphilic block copolymers are simultaneously synthesized and self-assembled in a selective solvent, leading to nanoparticles of different morphologies. Copolymerization has been reported as a means to tune…

Polyoxotungstates-stabilized gold nanoparticles: how to transfer from an aqueous suspension to CH3CN ?, Nanoparticules d'or stabilisées par des polyoxotungstates : comment passer d'une suspension aqueuse à CH3CN ?

Richard Villanneau, Jean-Baptiste Harlé, Élise Péruse, Jimika Hassanaly, Dalil Brouri, Anna Proust, Audrey Denicourt-Novicky, Alain Roucoux, Anne Gauvin-Bialecki

The present study aimed to evaluate available methods for preparing suspensions of gold nanopar*cles stabilized by polyoxometalates (POMs@AuNPs) in CH₃CN, a solvent commonly used in oxida*on reac*ons. POMs@AuNPs were successfully synthesized in CH₃CN using three different approaches: (i) in situ…

Ionic liquid redox flow membraneless battery in microfluidic system

Nesrine Chaabene, Kieu Ngo, Mireille Turmine, Vincent Vivier

Redox flow batteries (RFBs) often require the presence of a physical membrane to separate the two compartments of the battery. The objective of this work is to develop a membraneless microfluidic redox flow battery (RFB) by using 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (…

Evidence of Pd segregation and stabilization at edges of AuPd nano-clusters in the presence of CO: A combined DFT and DRIFTS study

Beien Zhu, Gode Thrimurthulu, Laurent Delannoy, Catherine Louis, Christine Mottet, Jerome Creuze, Bernard Legrand, Hazar Guesmi

Combined Density Functional Theory (DFT) calculations and Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) were performed to study the distribution of Pd atoms in bimetallic AuPd nanoparticles in the presence of adsorbed CO. Compared to vacuum condition, the results showed…

Integrated stopped-flow device for the study of porous materials using hyperpolarized $^{129}$Xe NMR

Jing Li, Estelle Léonce, Corentin Coutellier, Céline Boutin, Kévin Chighine, Charles Rivron, Anne Davidson, Patrick Berthault

A simple, low-cost, and efficient device is proposed for the study of porous materials via NMR using small gas probes. Mainly built through additive manufacturing and being equipped with a radiofrequency solenoid microcoil, it only requires tiny quantities of sample and/or gas and is particularly…

Halide Ligands to Release Strain in Cadmium Chalcogenide Nanoplatelets and Achieve High Brightness

Marion Dufour, Junling Qu, Charlie Gréboval, Christophe Méthivier, Emmanuel Lhuillier, Sandrine Ithurria

Zinc blende II-VI semiconductor nanoplatelets (NPLs) are defined at the atomic scale along the thickness of the nanoparticle and are initially capped with carboxylates on the top and bottom [001] facets. These ligands are exchanged on CdSe NPLs with halides that act as X-L-type ligands. These CdSe…

Physical techniques and catalyst preparation: Determining the interactions of transition-metal complexes with oxide surfaces

Xavier Carrier, Eric Marceau, Michel Che

This contribution presents the molecular approach used to investigate the different preparation steps of important catalytic systems, based on Mo, Ni, and Co. The first preparation step consists of impregnating oxide supports by aqueous solutions of transition-metal complexes (TMCs), called…

Deciphering pathological remodelling of the human cartilage extracellular matrix in osteoarthritis at the supramolecular level

Ilhem Lilia Jaabar, Pauline Cornette, Antoine Miche, Kristell Wanherdrick, Vincent Dupres, François-Paul Ehkirch, Adeline Cambon Binder, Francis Berenbaum, Xavier Houard, Jessem Landoulsi

Osteoarthritis induces a combination of chemical, structural and nanomechanical changes to collagen fibrils and aggrecan aggregates, the main building blocks of cartilage ECM, that may be mimicked by specific enzymatic reactions.
