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…

Conception de systèmes catalytiques hétérogènes chimioenzymatiques pour l'époxydation, Conception of heterogeneous chemioenzymatic catalysts for epoxydation

Noémie Balistreri

L'objectif de ce travail est de développer un système catalytique hétérogène pour l'époxydation en utilisant directement O2 de l'air plutôt que H2O2 commercial. La stratégie adoptée a été de coupler la production in situ de H2O2, catalysée par la glucose oxydase (GOx), avec un…, The objective of this work was to develop an heterogeneous catalyst system supplied by dioxygen, rather than commercial H2O2, in order to carry out epoxidation reactions. Our strategy was to couple the in situ production of H2O2, catalyzed by glucose oxidase (GOx), with a Ti-based catalyst. The…

Stabilization of hexagonal close-packed metallic nickel for alumina-supported systems prepared from Ni(II) glycinate

Eric Marceau, Vicente Rodriguez-Gonzalez, Michel Che, Patricia Beaunier, Cyrille Train

The decomposition in flowing argon of the neutral complex [NiII(glycinate)2(H2O)2] leads to a mixture of face-centered cubic (fcc) and hexagonal close-packed (hcp) metallic nickel. The latter is the main phase when the Ni(II) complex is supported on alumina. Unlike most hexagonal Ni phases…

Approach for Plasmonic Based DNA Sensing: Amplification of the Wavelength Shift and Simultaneous Detection of the Plasmon Modes of Gold Nanostructures

Jolanda Spadavecchia, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

In this article, the detection of DNA hybridization taking advantage of the plasmonic properties of gold nanostructures is described. The approach is based on the amplification of the wavelength shift of a multilayered localized surface plasmon resonance (LSPR) sensor interface upon hybridization…

Recent advances in aptasensors based on graphene and graphene-like nanomaterials

Jianfeng Ping, Yubin Zhou, Yuanyuan Wu, Vladislav Papper, Souhir Boujday, Robert S. Marks, Terry W.J. Steele

Graphene and graphene-like two-dimensional nanomaterials have aroused tremendous research interest in recent years due to their unique electronic, optical, and mechanical properties associated with their planar structure. Aptamers have exhibited many advantages as molecular recognition elements for…

Bioactive peptides grafted silicone dressings: A simple and specific method

Coline Pinese, Said Jebors, Pierre-Emmanuel Stoebner, Vincent Humblot, Pascal Verdié, Léa Causse, Xavier Garric, Hubert Taillades, Jean Martinez, Ahmad Mehdi, Gilles Subra

The need for bioactive dressings increases with the population aging and the prevalence of chronic diseases. In contrast, there are very few dressings on the market which are designed to display a chosen bioactivity. In this context, we investigated the surface-functionalization of silicone wound…

Effect of the order of Ni and Ce addition in SBA-15 on the activity in dry reforming of methane, Effet de l'ordre d'ajout du Ni et du Ce dans SBA-15 sur l'activité en reformage à sec du methane

Marie-Nour Kaydouh, Nissrine El Hassan, Anne Davidson, Sandra Casale, Pascale Massiani

Dry reforming of methane has been carried out on SBA-15 catalysts containing 5 wt% Ni and 6 wt% Ce. The effect of the order of Ni and Ce impregnation on the catalytic activity has been studied. Both metals were added using the “two-solvent” method that favors metal dispersion inside the pores.…

The controlled synthesis of metal-acid bifunctional catalysts: The effect of metal:acid ratio and metal-acid proximity in Pt silica-alumina catalysts for n-heptane isomerization

Jadid E Samad, Juliette R Blanchard, Celine R Sayag, Catherine R Louis, John R Regalbuto

Several series of metal-acid bifunctional catalysts with controlled metal:acid ratios and metal site-acid site proximity were evaluated for n-heptane isomerization. Through the study of metal deposition reported in the companion paper, proximity could be achieved at four distinct scales: atomic,…
