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…

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…

Modelling of a Lean NOx-Trap system with NO/NO2 differentiation and sulfur poisoning

Alexis Manigrasso, Pierre Darcy, Patrick da Costa

One of the challenges in the automotive industry is to develop new vehicles and new technologies with minimal costs. In this context, modeling becomes an important tool for the design of future technologies by reducing the number of tests needed to develop a new exhaust system. With the emergence…

Fast and potent bactericidal membrane lytic activity of PaDBS1R1, a novel cationic antimicrobial peptide

Luz N Irazazabal, William F Porto, Isabel C.M. Fensterseifer, Eliane S.F. Alves, Carolina Matos, Antônio C.S. Menezes, Mário R Felício, Sónia Gonçalves, Nuno Santos, Suzana M Ribeiro, Vincent Humblot, Luciano M Lião, Ali Ladram, Octavio L Franco

Antimicrobial peptides (AMPs) are promising candidates for the development of future antibiotics. In an attempt to increase the efficacy of therapeutic AMPs, computer-based design methods appear as a reliable strategy. In this study, we evaluated the antimicrobial efficiency and mechanism of action…

Modifying protein adsorption by layers of glutathione pre-adsorbed on Au(111).

Anne Vallée, Vincent Humblot, Christophe Méthivier, Paul Dumas, Claire-Marie Pradier

Molecular interaction with metal surfaces raises fundamental questions regarding their binding tendency, their dispersion on the surface, as well as their conformation which may change their biological properties; addressing these questions, and being able to tune protein interactions, is of…
