Extension of a kinetic model for NO oxidation and NOx storage to fixed-bed Pt/Ba/Al2O3 catalysts

Nikola Rankovic, Andre Nicolle, David Berthout, Patrick da Costa

Following our work on modeling of monolith catalysts, we herein focus on developing a fixed-bed reactor model in the AMESim modeling platform. A kinetic model for NO oxidn. and NOx storage over Pt/Ba/Al2O3 recently developed in the literature was successfully implemented and validated against the…

Light olefin transformation over ZSM-5 zeolites with different acid strengths - A kinetic model

P. Oliveira, P. Borges, R. Ramos Pinto, M. A. N. D. A. Lemos, F. Lemos, Jacques C. Vedrine, F. Ramoa Ribeiro

The authors analyzed the influence of the acidity of a ZSM-5 catalyst on the catalytic transformation of various short-chain olefins (ethylene, propylene and 1-butene). Four ZMS-5 catalysts with different acid strength distributions were studied at different temps. and partial pressures. The…

Quantifying Cell Traction Forces at the Individual Fiber Scale in 3D: A Novel Approach Based on Deformable Photopolymerized Fiber Arrays

Pierre Ucla, Joanne Le Chesnais, Henri Ver Hulst, Xingming Ju, Isabel Calvente, Ludovic Leconte, Jean Salamero, Isabelle Bonnet, Catherine Monnot, Hélène Moreau, Jessem Landoulsi, Vincent Semetey, Sylvie Coscoy

The forces exerted by cells upon the fibers of the extracellular matrix play a decisive role in cell motility in development and disease. How the local physical properties of the matrix (such as density, stiffness, orientation) affect cellular forces remains poorly understood. Existing approaches…

Preparation of two series of VxSiBeta zeolite catalysts with V centres in framework and extra-framework positions and their application in selective oxidation of methanol

Maciej Trejda, Yannick Millot, Karolina Chalupka, Stanislaw Dzwigaj

Two series of V-containing Beta zeolites have been prepared by contacting of the aqueous NH 4 VO 3 solution with two SiBeta zeolites at pH = 2.5 and 6, respectively. Because of the presence in NH 4 VO 3 solution at pH = 2.5 mainly monomeric VO 2 + ions, vanadium have been easily incorporated into…

Polyol Process Coupled to Cold Plasma as a New and Efficient Nanohydride Processing Method: Nano-Ni 2 H as a Case Study

Sonia Haj-Khlifa, Sophie Nowak, Patricia Beaunier, Patricia de Rango, Michaël Redolfi, Souad Ammar-Merah

An alternative route for metal hydrogenation has been investigated: cold plasma hydrogen implantation on polyol-made transition metal nanoparticles. This treatment applied to a challenging system, Ni-H, induces a reordering of the metal lattice, and superstructure lines have been observed by both…

Metallomics in deep time and the influence of ocean chemistry on the metabolic landscapes of Earth's earliest ecosystems

Keyron Hickman-Lewis, Barbara Cavalazzi, Stéphanie Sorieul, Pascale Gautret, Frédéric Foucher, Martin Whitehouse, Heejin Jeon, Thomas Georgelin, Charles Cockell, Frances Westall

Modern biological dependency on trace elements is proposed to be a consequence of their enrichment in the habitats of early life together with Earth's evolving physicochemical conditions; the resulting metallic biological complement is termed the metallome. Herein, we detail a protocol for…

Structure and Surface Study of Hydroxyapatite-Based Materials: Experimental and Computational Approaches

Guylène Costentin, Christophe Drouet, Fabrice Salles, Stéphanie Sarda

In addition to designing catalytic materials ever more active and selective, the emergence of new classes of greener catalysts remains very challenging. The apatite family system with hydroxyapatite (HA) structure appears as a good candidate for catalysis due to its eco-compatibility properties,…
