Metal–Support Interactions in Pt-WO 3 Heterostructures: Role of WO 3 Polymorphism

Isabel Gómez-Recio, Cyril Thomas, Christophe Méthivier, María Luisa Ruiz-González, José González-Calbet, David Portehault

Ionic exchange under soft conditions yields nanoplatelets of tungsten bronzes with an original crystal structure doped with cobalt, copper, platinum, and cesium cations (h′-MxWO3). The optimal orientation of the tunnel-based crystal structure, perpendicular to the basal plane of the nanoplatelets,…

Phosphorylation of a conserved serine in the deoxyribonucleic acid binding domain of nuclear receptors alters intracellular localization.

Kai Sun, Vedrana Montana, Karthikeyani Chellappa, Yann Brelivet, Dino Moras, Yutaka Maeda, Vladimir Parpura, Bryce M Paschal, Frances M Sladek

Nuclear receptors (NRs) are a superfamily of transcription factors whose genomic functions are known to be activated by lipophilic ligands, but little is known about how to deactivate them or how to turn on their nongenomic functions. One obvious mechanism is to alter the nuclear localization of…

Gold Nanoparticles on Oxide-Free Silicon-Molecule Interface for Single Electron Transport

Louis Caillard, Oliver Seitz, Philip M. Campbell, Rachel P. Doherty, Anne-Félicie Lamic-Humblot, Emmanuelle Lacaze, Yves J. Chabal, Olivier Pluchery

Two different organic monolayers were prepared on silicon Si(111) and modified for attaching gold nanoparticles. The molecules are covalently bound to silicon and form very ordered monolayers sometimes improperly called self-assembled monolayers (SAM). They are designed to be electrically…

Covalent Transition Metal Borosilicides: Reaction Pathways in Molten Salts for Water Oxidation Electrocatalysis

Daniel Janisch, Fernando Igoa Saldaña, Edouard de Rolland Dalon, Carlos V. M. Inocêncio, Yang Song, Pierre-Olivier Autran, Antoine Miche, Sandra Casale, David Portehault

The properties of transition metal borides and silicides are intimately linked to the covalent character of the chemical bonds within their crystal structures. Bringing boron and silicon together within metal borosilicides can then engender different competing covalent networks and complex charge…

Depuis la nuit des temps, l’homme a fabriqué et utilisé des produits cosmétiques. De la Gaule à l’Egypte, en passant par l’Empire Romain et la Grèce antique, les hommes et les femmes s’appliquaient sur le visage et le corps des produits naturels ou transformés (huiles, poudres, mixtures, laits, etc…, Since the dawn of time, man has manufactured and used cosmetic products. From Gaul to Egypt, passing through the Roman Empire and ancient Greece, men and women applied to the face and body of natural or processed products (oils, powders, mixtures, milks, etc.) in order to embellish oneself, to heal…

Atomic Scale Observation of the Structural Dynamics of Supported Gold Nanocatalysts under 1,3‐Butadiene by in situ Environmental Transmission Electron Microscopy

Abdallah Nassereddine, Laurent Delannoy, Christian Ricolleau, Catherine Louis, Alloyeau D., Guillaume Wang, Qing Wang, Hazar Guesmi, Jaysen Nelayah

Supported gold catalysts have been reported to exhibit exceptional selectivity towards the desirable product, an alkene, in chemoselective hydrogenation of highly unsaturated alkynes and alkadienes. However, insights on the interactions between the gold nanoparticles and the 1,3‐butadiene…

Direct grafting of ethylene sulfide onto silicic acid magadiite

Michelle Menezes de Oliveira, Marcia Maria Fernandes, Maria Gardennia Fonseca, Edson Cavalcanti da Silva Filho, Antonio Gouveia de Souza, Fabrice Gaslain, Maguy Jaber

Acidic magadiite (HMag) was directly reacted with ethylene sulfide (ES) under various controlled conditions producing an intercalated hybrid silicate (MagS). The sodium, acidic and modified magadiites were characterized using elemental analysis, thermogravimetric analysis (TGA/DTG), infrared…

Conversion of xylene over mordenites: an operando infrared spectroscopy study of the effect of Na+

Pascale Massiani, Olivier Marie, Frédéric Thibault-Starzyk

A series of progressively proton-exchanged sodium mordenite samples was studied by operando infrared spectroscopy during xylene conversion. This unique, powerful tool allowed us to characterize the species adsorbed to the surface during catalysis and to follow the evolution of the active sites as…
