Chemical Differentiation of Planets: A Core Issue

Hervé Toulhoat, Viacheslav Zgonnik

By plotting empirical chemical element abundances on Earth relative to the Sun and normalized to silicon versus their first ionization potentials, we confirm the existence of a correlation reported earlier. To explain this, we develop a model based on principles of statistical physics that predicts…

Développement de biocathodes pour biopiles enzymatiques utilisant la laccase, Development of an enzymatic cathode biofuel cell using laccase

Mohamed Achraf Blout

Les biopiles enzymatiques constituent une alternative intéressante de production d'électricité renouvelable. On s'est intéressé dans ce travail au compartiment cathodique d'une biopile utilisant la laccase, une oxydase multi-cuivres, comme biocatalyseur pour la réduction de l'…, Enzymatic biofuel cells are an attractive alternative for renewable electricity generation. In this work, we are focusing on the cathodic compartment of a biofuel cell using laccase, a multi-copper oxidase, as biocatalysts for the oxygen reduction reaction (ORR) by direct electron transfer of…

Surface segregation in AuPd alloys: Ab initio analysis of the driving forces

Jérôme Creuze, Hazar Guesmi, Christine Mottet, Beien Zhu, Bernard Legrand

In order to determine the energetic driving forces for surface segregation in AuPd alloys, we use a combined approach coupling ab initio calculations and an analysis via an effective Ising model. Previously, this approach has been used successfully in the framework of N-body interatomic potentials…

Electron transfers in a TiO₂-containing MOR zeolite: Synthesis of the nanoassemblies and application using a probe chromophore molecule

A. Legrand, A. Moissette, M. Hureau, S. Casale, P. Massiani, H. Vezin, A.S. Mamede, I. Batonneau-Gener

New assemblies constituted by a microporous matrix of mordenite (MOR) zeolite on which TiO₂ nanoclusters are deposited were synthesized using ionic oxalate complexes and TiCl₃ titanium precursors. The samples were used to investigate the transfer of…

Enhanced selectivity of 3-D ordered macroporous Pt/Al2O3 catalysts in nitrites removal from water

A.C. Sunil Sekhar, A. Zaki, S. Troncea, S. Casale, C.P. Vinod, J.P. Dacquin, P. Granger

Tailored macroporous mesoporous alumina supports have been successfully prepared using a single hard templating approach. Pt nanoparticles, showing similar physico-chemical properties, were homogeneously dispersed throughout the different alumina frameworks as catalytic active phase for drinking…

Scanning Electrochemical Microscopy for Investigating Gas Bubble/Liquid Interfaces

Claude Gabrielli, François Huet, Michel Keddam, Philippe Rousseau, Vincent Vivier

Scanning electrochemical microscopy was used to characterize air bubble/electrolyte interfaces for bubbles of diameter in the millimeter range. Contrary to rigid insulated substrate/liquid interfaces, the approach of the tip of the microelectrode was shown to lead to a deformation of the bubble…

Enhancing low-temperature activity and durability of Pd-based diesel oxidation catalysts using ZrO2 supports

Mi-Young Kim, Eleni A. Kyriakidou, Jae-Soon Choi, Todd J. Toops, Andrew J. Binder, Cyril Thomas, James E. Parks, Viviane Schwartz, Jihua Chen, Dale K. Hensley

We investigated the impact of ZrO2 on the performance of palladium-based oxidation catalysts with respect to low-temperature activity, hydrothermal stability, and sulfur tolerance. Pd supported on ZrO2 and SiO2 were synthesized for a comparative study. Additionally, in an attempt to maximize the…

Controlling the reproducibility of Coulomb blockade phenomena for gold nanoparticles on an organic monolayer/silicon system

L Caillard, S Sattayaporn, A-F Lamic-Humblot, S Casale, P Campbell, y J Chabal, Olivier Pluchery

Two types of highly ordered organic layers were prepared on silicon modified with an amine termination for binding gold nanoparticles (AuNPs). These two grafted organic monolayers (GOMs), consisting of alkyl chains with seven or 11 carbon atoms, were grafted on oxide-free Si(111) surfaces as tunnel…
