Mechanistic Investigation of Isopropanol Conversion on Alumina Catalysts: Location of Active Sites for Alkene/Ether Production

Kim Larmier, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Johnny Abboud, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Alcohol dehydration is of prominent relevance in the context of biomass conversion. This reaction can be efficiently catalyzed by alumina surfaces, but the nature of active sites, the mechanisms involved, and the key parameters to tune both the activity and the alkene/ether selectivity remain a…

Molecular mechanism of barnacle adhesion : a structural approach and underlying biochemistry, Mécanisme moléculaire de l'adhésion des balanes : approche structurale et biochimie sous-jacente

Sunyoung Hur

Barnacles adhere themselves robustly and permanently to diverse underwater substrates through strong interactions of a multi-protein complex layer called the “cement”. However, the intermolecular interactions responsible for the strong adhesive properties of the barnacle cement remains poorly…, Les balanes adhèrent de manière robuste et permanente à divers substrats sous-marins grâce à de fortes interactions d’une couche complexe multiprotéique appelée « ciment ». Cependant, les interactions intermoléculaires responsables des fortes propriétés adhésives du ciment de bernacle restent mal…

Structure–Activity Relationship in Manganese Perovskite Oxide Nanocrystals from Molten Salts for Efficient Oxygen Reduction Reaction Electrocatalysis

Francisco Gonell, Carlos M Sánchez-Sánchez, Vincent Vivier, Christophe Méthivier, Christel Laberty-Robert, David Portehault

We report a synthesis pathway in molten salts toward ligand-free nanoparticles of the layered perovskite La0.5Sr1.5MnO4 (l-LSMO) and of the pseudocubic perovskite La0.7Sr0.3MnO3 (pc-LSMO). These particles are readily implemented as oxygen reduction reaction (ORR) electrocatalysts in alkaline…

This thesis reports on the adsorption of two amino acids (AA) with different properties, Leucine and Glutamic acid, on the amorphous silica surface. It exemplifies a general approach to hybrid systems that combines experimental information and molecular modeling in order to characterize at the…, Cette thèse porte sur l'adsorption de deux acides aminés aux propriétés différentes, la leucine et l'acide glutamique, sur la surface de la silice amorphe. Une combinaison d'informations expérimentales et de modélisation moléculaire a été entreprise afin de caractériser au niveau…

Biomineralization Patterns of Intracellular Carbonatogenesis in Cyanobacteria: Molecular Hypotheses

Jinhua Li, Isabel Margaret-Oliver, Nithavong Cam, Thomas Boudier, Marine Blondeau, Eric Leroy, Julie Cosmidis, Feriel Skouri-Panet, Jean-Michel Guigner, Céline Férard, Melanie Poinsot, David Moreira, Purificacion Lopez-Garcia, Corinne Cassier-Chauvat, Franck Chauvat, Karim Benzerara

The recent discovery of intracellular carbonatogenesis in several cyanobacteria species has challenged the traditional view that this process was extracellular and not controlled. However, a detailed analysis of the size distribution, chemical composition and 3-D-arrangement of carbonates in these…

Understanding of the oxygen activation on ceriaand ceria/alumina-supported gold catalysts: a study combining 18O/16O isotopic exchange and EPR spectroscopy

Pandian Lakshmanan, Frédéric Averseng, Nicolas Bion, Laurent Delannoy, Jean-Michel Tatibouet, Catherine Louis

Gold supported on ceria or ceria-alumina mixed oxides are very active catalysts for total oxidation of a variety of molecules. The key step of the oxygen activation on such catalysts is still a matter of debate. Gold-ceria (Au/CeO2) and gold-ceria-alumina (Au/CeO2/Al2O3) catalysts were prepared by…

Enzymatic Approach in Calcium Phosphate Biomineralization: A Contribution to Reconcile the Physicochemical with the Physiological View

Clément Guibert, Jessem Landoulsi

Biomineralization is the process by which organisms produce hard inorganic matter from soft tissues with outstanding control of mineral deposition in time and space. For this purpose, organisms deploy a sophisticated “toolkit” that has resulted in significant evolutionary innovations, for which…
