Surface response methodology for the study of supported membrane formation.

C. Rossi, Elisabeth Briand, P. Parot, Michaël Odorico, Joël Chopineau

We report on the investigations of the formation of the tethered lipid bilayer by vesicle deposition on amine-functionalized surfaces. The tethered bilayer was created by the deposition of egg-PC vesicles containing 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-poly-(ethyleneglycol)-N-…

Comparison of molybdenum carbide and tungsten carbide for the hydrodesulfurization of dibenzothiophene

Agnieszka Szymanska-Kolasa, Marek Lewandowski, Celine Sayag, G. Djéga-Mariadassou

The molybdenum and tungsten carbides (Mo2C and W2C) were synthesized, characterized and tested in hydrodesulfurization (HDS) of dibenzothiophene (DBT). The phase purity of these catalysts was established by X-ray diffraction (XRD), and the surface properties were determined by N2 BET specific…

Transformations of γ-alumina in aqueous suspensions. 1. Alumina chemical weathering studied as a function of pH

Xavier Carrier, Eric Marceau, Jean-François Lambert, Michel Che

Hydration of γ-Al2O3 is often reported to occur via the superficial transformation of the alumina surface into alumina hydroxide-like layers. However, very little evidence has been given so far to support this hypothesis. It is demonstrated here by X-ray diffraction, TEM, electron diffraction and…

New insights into the development of Brønsted acidity of niobic acid

Vanessa Lebarbier, Marwan Houalla, Thomas Onfroy

The development of Brønsted acidity and the relationship between acidity, catalytic performance and structure of niobium oxide were investigated for a series of samples prepared by calcination of niobic acid at temperatures between 423 and 823 K. All solids were active for propan-2-ol dehydration.…

Selective catalytic reduction of NO on single site FeSiBEA zeolite catalyst: Influence of the C1 and C2 reducing agents on the catalytic properties

Janusz Janas, Wojciech Rojek, Tetsuya Shishido, Stanislaw Dzwigaj

FeSiBEA zeolite with 0.8 Fe wt% is prepared in acidic condition (pH 2.5) by a two-step postsynthesis method which allows to incorporate iron into framework of zeolite as mononuclear distorted tetrahedral Fe(III) species, as evidenced by XRD, diffuse reflectance UV-vis and X-ray absorption…

Surface plasmon resonance biosensors incorporating gold nanoparticles.

Erin Bedford, Jolanda Spadavecchia, Claire-Marie Pradier, Frank Gu

SPR biosensing is increasingly popular for the detection of a multitude of biomolecules. It offers label-free detection and study of proteins, nucleic acids, and other biomolecules in real time. A recent trend involves incorporation of AuNPs, either within the sensing surface itself or as signal…

Bioconjugated gold nanorods to enhance the sensitivity of FT-SPR-based biosensors

Jolanda Spadavecchia, Sandra Casale, Souhir Boujday, Claire-Marie Pradier

n this paper, we report a feasible solvent-free approach for the synthesis and self-assembling of gold nanorods after bioconjugation to antibodies; scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed a remarkable shape and size narrow distribution, as well…

Synthesis of Well-Defined Dawson-Type Poly(N,N-diethylacrylamide) Organopolyoxometalates

Jennifer Lesage de la haye, Patricia Beaunier, Laurent Ruhlmann, Bernold Hasenknopf, Emmanuel Lacôte, Jutta Rieger

An organotin-substituted Dawson-type phosphotungstate was covalently linked to a trithiocarbonate group by postfunctionalization methods. This organopolyoxometalate led to a series of polyoxometalate (POM)–poly(N,N-diethylacrylamide) hybrids in a controlled way through reversible addition–…

Mesoporous nickel-alumina catalysts derived from MIL-53(Al) metal-organic framework: A new promising path for synthesizing CO2 methanation catalysts

Leila Karam, Maria C Bacariza, José M Lopes, Carlos Henriques, Julien Reboul, Nissrine El Hassan, Pascale Massiani

A new synthesis route for the preparation of highly efficient and stable porous Ni-based alumina catalysts for CO2 methanation is presented. It is based on the use of MIL-53(Al), an Al-containing metal-organic framework (MOF) with high surface area, as sacrificial support. A series of Ni-Al2O3…
