Design of model tokamak particles for future toxicity studies: Morphology and physical characterization

E. Bernard, F. Jambon, I. Georges, M. Sanles Sobrido, Jérôme Rose, N. Herlin-Boime, F. Miserque, P. Beaunier, D. Vrel, S. Dine, E. Hodille, J. Chêne, S. Garcia-Argote, G. Pieters, S. Peillon, F. Gensdarmes, G. Dinescu, T. Acsente, Chiara Uboldi, Thierry Orsière, Veronique Malard, B. Rousseau, G. Dine, Ph. Delaporte, C Grisolia

During ITER operation, it is expected that the large panel of plasma-wall interactions triggers the production of dust particles from the tungsten and beryllium first wall. These particles can be loaded with tritium (T) used as a fuel for the fusion reaction; T inventory is of prime importance for…

Aqueous-Phase Preparation of Model HDS Catalysts on Planar Alumina Substrates: Support Effect on Mo Adsorption and Sulfidation

Cédric Bara, Lucie Plais, Kim Larmier, Elodie Devers, Mathieu Digne, Anne-Félicie Lamic-Humblot, Gerhard D. Pirngruber, Xavier Carrier

The role of the oxide support on the structure of the MoS2 active phase (size, morphology, orientation, sulfidation ratio, etc.) remains an open question in hydrotreating catalysis and biomass processing with important industrial implications for the design of improved catalytic formulations. The…

A new glance at ruthenium sorption mechanism on hydroxy, carbonate, and fluor apatites: Analytical and structural studies

K. Tõnsuaadu, M. Gruselle, F. Villain, R. Thouvenot, M. Peld, V. Mikli, R. Traksmaa, Patrick Gredin, Xavier Carrier, L. Salles

The sorption mechanism of Ru3+ ions on hydroxy (HAp), carbonate (CO3HAp), and fluor apatites (FAp) has been studied in detail. Ru apatites were obtained by reaction of the apatites with RuCl3 in aqueous solution. The structure and composition of the ruthenium-modified apatites were studied by…

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…
