Selective gas phase hydrogenation of nitroarenes over Mo 2 C-supported Au-Pd

Xiaodong Wang, Noémie Perret, Laurent Delannoy, Catherine Louis, Mark A. Keane

We report the first synthesis of Mo2C-supported Au and Au–Pd catalysts (nominal Au/Pd = 10 and 30) obtained from colloidal nanoparticles stabilised by polyvinyl alcohol (PVA). Equivalent Au/Al2O3 and Au–Pd/Al2O3 were prepared and served as benchmarks. Residual PVA was removed by thermal treatment…

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…

Coupled quartz crystal microbalance – Surface enhanced Raman scattering strategy for the design and testing of aptasensors for small analytes

Médéric Lequeux, Michèle Salmain, Jean-Marc Krafft, Jakub Dostalek, Anne Vallée, Alexis Loiseau, Wolfgang Knoll, Marc Lamy de la Chapelle, Souhir Boujday

Both quartz crystal microbalance with dissipation (QCM-D) and Surface Enhanced Raman Scattering (SERS) stand at the forefront of label-free transducing techniques to trace and monitor biomolecular association events occurring at solid-liquid interfaces. Although these techniques provide highly…

From 8-hydroxy-5-sulfoquinoline to new related fluorogenic ligands for complexation of aluminium(III) and gallium(III)

Franck Launay, Valérie Alain-Rizzo, Émilie Destandau, Nathalie Ramos, Ēlisabeth Bardez, Paul Baret, Jean-Louis Pierre

The hexadentate tripodal ligand O-TRENSOX (already known as a siderophore), incorporating three 8-hydroxy-5- sulfoquinoline (8-HQS) subunits, was investigated as a potential Ñuorogenic ligand of Al(III) and Ga(III). For the sake of comparison, every chelation study was also carried out with n-BUSOX…

Effect of Ca-doping on microstructure and photocatalytic activity of ZnO nanoparticles synthesized by sol gel method

R. Slama, J. El Ghoul, K. Omri, A. Houas, L. El Mir, Franck Launay

We report the synthesis of Zn1−xCaxO nanoparticles prepared by a sol–gel processing technique for x ranging from 0 to 0.05. The structural, morphological and optical properties of the nanoparticles were investigated by X-ray diffraction, transition electron microscopy, UV measurements, and…

Controlling the Nucleation of a Semicrystalline Polymer by Inducing Compartmentalization of Competitive Nucleating Agents

Arnaud Y.‐g. Delplanque, Sandra Casale, Bruno Bresson, Paolo Edera, Clément Guibert, Nathan J van Zee

Many functional polymeric systems have been inspired by the principle of compartmentalization, a ubiquitous form of hierarchical assembly found in Nature. For instance, polymers have been elaborated with microcapsules that release a chemical payload upon activation by an external stimulus. A…

Hydrothermally stable Pd/SiO2@Zr Core@Shell catalysts for diesel oxidation applications

Chih-Han Liu, Junjie Chen, Todd Toops, Jae-Soon Choi, Cyril Thomas, Michael Lance, Eleni Kyriakidou

Hydrothermally stable diesel oxidation catalysts (DOCs) with improved low-temperature activity are desired for the abatement of emissions from diesel vehicles. Herein, novel palladium(Pd)/SiO2(core)@Zr(shell) structured DOCs were developed. SiO2 was completely covered by an 8.4 nm thickness Zr-…
