Adsorption of l-DOPA Intercalated in Hydrated Na-Saponite Clay: A Combined Experimental and Theoretical Study

K. El Adraa, V. Timon, J.-F. Lambert, Abdel-Rahman Al-Rabaa, F. Jaber, M. Jaber, Frederik Tielens

The intercalation of L-DOPA into the interlayer space of saponite, a 2:1 phyllosilicate, and the nature of host−guest interactions are investigated by a combined experimental and theoretical approach. L-DOPA zwitterions are accommodated vertically in the interlayer region as a bilayer of partially…

Importance of the Nature of the Active Acid/Base Pairs of Hydroxyapatite Involved in the Catalytic Transformation of Ethanol to n ‐Butanol Revealed by Operando DRIFTS

Manel Ben Osman, Jean‐marc Krafft, Cyril Thomas, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Operando DRIFTS is used to identify the nature and the role of the surface sites of hydroxyapatites (HAps) involved in the catalytic transformation of ethanol to n‐butanol. The surface processes occurring upon a first reaction step followed by a step under He flow greatly influence the reactivity…

Ultra-Compact Electrical Double Layers at TiO₂ (110) Electrified Interfaces

Immad Nadeem, Christopher Penschke, Ji Chen, Xavier Torrelles, Axel Wilson, Hadeel Hussain, Gregory Cabailh, Oier Bikondoa, Jameel Imran, Christopher Nicklin, Robert Lindsay, Jörg Zegenhagen, Matthew Blunt, Angelos Michaelides, Geoff Thornton

Metal-oxide aqueous interfaces are important in areas as varied as photocatalysis and mineral reforming. Crucial to the chemistry at these interfaces is the structure of the electrical double layer formed when anions or cations compensate for the charge arising from adsorbed H<sup>+</sup…

Phosphoribosyl Pyrophosphate: A Molecular Vestige of the Origin of Life on Minerals

Mariame Akouche, Maguy Jaber, Marie-Christine Maurel, Jean-François Lambert, Thomas Georgelin

In this contribution, we report the formation under prebiotic conditions of phosphoribosyl pyrophosphate (PRPP) as a molecular precursor in the one-pot synthesis of a canonical nucleotide, namely adenosine monophosphate (AMP) from its building blocks (KH2PO4 or Pi, adenine, and d-ribose), on a…

Chemical Modifications of Au/SiO2 Template Substrates for Patterned Biofunctional Surfaces

Elisabeth Briand, Vincent Humblot, Jessem Landoulsi, Sarunas Petronis, Claire-Marie Pradier, Bengt Kasemo, Sofia Svedhem

The aim of this work was to create patterned surfaces for localized and specific biochemical recognition. For this purpose, we have developed a protocol for orthogonal and material-selective surface modifications of microfabricated patterned surfaces composed of SiO2 areas (100 mu m diameter)…

Nickel Coordination to Lattice Oxygens in Basic LSX, X and Y Sodium Faujasites: A DFT Study

Hazar Guesmi, Dominique Costa, Dorothée Berthomieu, Pascale Massiani

The location and coordination of nickel cations inside the hexagonal prism of dehydrated sodium faujasites have been investigated as a function of the framework Al content and distribution by density functional theory (DFT) calculations. Three different Si/Al ratios have been considered in order to…

Self-assembled multilayers based on native or denatured collagen: mechanism and synthesis of size-controlled nanotubes

Jessem Landoulsi, Sophie Demoustier-Champagne, Christine Dupont-Gillain

The mechanism of layer-by-layer (LbL) assembly using collagen, the major protein of the extracellular matrix, was investigated on flat substrates and in nanoporous templates, with a view to synthesize collagen-contg. nanotubes. The effect of parameters related to geometrical constraints (flat…

Synthesis and Unique Catalytic Performance of Single-Site Ti-Containing Hierarchical Macroporous Silica with Mesoporous Frameworks

Takashi Kamegawa, Norihiko Suzuki, Michel Che, Hiromi Yamashita

Single-site Ti-containing hierarchical macroporous silica with mesoporous frameworks (Ti-MMS) was successfully prepared by a solvent evaporation method using organic surfactant and poly(methyl methacrylate) (PMMA) colloidal crystals as the template. The formation of a well-defined macroporous…

Detailed kinetic modeling study of NOx oxidation and storage and their interactions over Pt/Ba/Al2O3 monolith catalysts

Nikola Rankovic, Andre Nicolle, Patrick da Costa

The concept of nitrogen oxide storage-redn. (NSR) is a promising aftertreatment technol. for reducing NOx emissions from lean-burn engine exhaust. The present work focuses on the first two steps of the overall NSR mechanism, namely, NO to NO2 oxidn. and NOx storage. The governing storage mechanisms…
