Deciphering the role and nature of phosphate species at the surface of stainless steel immersed in phosphoric acid solutions

Irma Liascukiene, M. Ben Salah, Philippe Refait, Leila Dhouibi, Christophe Méthivier, Jessem Landoulsi, Marc Jeannin

We investigate the evolution of the surface of a highly alloyed stainless steel (Sanicro 28) upon immersion in aqueous phosphoric acid solutions. For this purpose, both short-(few hours) and long-term immersion (several days) were carried out. A detailed analysis of XPS spectra allowed a…

Long-Lived Charge-Separated States in ZnS/Na-MOR Zeolite upon <i>trans</i>-Stilbene Adsorption

Pedro Henrique Morais Andrade, Matthieu Hureau, Anne-Sophie Mamede, Pascale Massiani, Alexandre Legrand, Alain Moissette

Electron transfer (ET) processes are of fundamental importance in many photochemical processes in biological and chemical systems. Here, semiconductor nanoparticles of ZnS (as electron relay) and trans-stilbene molecules (t-St) (as electron donor), both confined within the porous volume of…

Probing the in-air growth of large area of 3D functional structures into a 2D supramolecular nanoporous network

Romain Brisse, Dominique Guianvarc’h, Christelle Mansuy, Sandrine Sagan, David Kreher, Lydia Sosa-Vargas, Lydia Hamitouche, Vincent Humblot, Imad Arfaoui, Vanessa Labet, Céline Paris, Christophe Petit, André-Jean Attias

Surface-confined host–guest chemistry at the air/solid interface is used for trapping a functionalized 3D Zn–phthalocyanine complex into a 2D porous supramolecular template allowing the large area functionalization of an sp2-hybridized carbon-based substrate as evidenced by STM, resonance Raman…

Direct Observation of the Surface Topography at High Temperature with SEM

Renaud Podor, X. F Le Goff, Joseph Lautru, H.P. Brau, Mathias Barreau, Xavier Carrier, Jerôme Mendonça, Dorian Nogues, Antoine Candeias

High-temperature scanning electron microscopy allows the direct study of the temperature behavior of materials. Using a newly developed heating stage, tilted images series were recorded at high temperature and 3D images of the sample surface were reconstructed. By combining 3D images recorded at…

Tuning the Growth Mode of 3D Silver Nanocrystal Superlattices by Triphenylphosphine

Karima Ouhenia-Ouadahi, Amandine Andrieux-Ledier, Johannes Richardi, Pierre-Antoine Albouy, Patricia Beaunier, Peter Sutter, Eli Sutter, Alexa Courty

Here, we show that the residual presence of reaction products markedly influences the growth mode of 3D superlattices made of silver nanocrystals. The silver nanocrystals (5 or 6 nm in diameter) are synthesized via the reduction of a silver triphenylphosphine complex in the presence of thiols. The…

Heavy-ion irradiation of interstellar carbonaceous and siliceous composite dust analogs. Cosmic ray-grain interactions at the nanometer scale

Eddy Abdo, Emmanuel Dartois, Marin Chabot, Olivier Sublemontier, Thibault Nguyen Trung, Emeline Charon, Frieder Koch, Pascal Simon, Ina Schubert, Marie Godard, Thomas Pino, Cécile Engrand, David Troadec, Sandra Casale, Joffrey Fréreux

Context. Interstellar dust made of siliceous and carbonaceous grains is exposed to cosmic ray ions in the diffuse and dense medium. This highly energetic interaction not only affects the morphology of such systems, but also plays a role in altering the surface and bulk chemistry. These two effects…

La Recherche en Chimie aux Frontières de la Connaissance

Dominique Massiot, Claire-Marie Pradier, Jacques Maddaluno, Jean-François Tassin, Joël Moreau, Mehran Mostafavi, Anne Imberty, Pascal Breuilles, Catherine Larroche

L’Unité Mixte de Recherche est la brique élémentaire, souple et pérenne d’un paysage de la recherche en évolution rapide. De nombreux dispositifs viennent structurer l’activité de ces équipes pour faire émerger des pôles de recherche, consolider le maillage des réseaux nationaux, identifier les…, Mixed research units are building blocks, flexible but permanent, in rapidly evolving fields of research. Several measures shape the activities of research teams and thus give rise to “poles of research”. They also help consolidate national networks, identify strong points, boost the sharing of top…

Heterogeneous catalyst preparation in ionic liquids: Titania supported gold nanoparticles

Camella Oumahi, Jean Lombard, Sandra Casale, Christophe Calers, Laurent Delannoy, Catherine Louis, Xavier Carrier

This work reports the use of ionic liquids (ILs) as solvent for the synthesis of Au/TiO2 heterogeneous catalysts. It is shown that the versatility of the physico-chemical properties of ILs makes them interesting solvents for a broad control of supported metal nanoparticles (NPs) size and for a fine…
