Relantionship between the feedstock powders reactivity and the Electrochemical properties of 316L Stainless steel obtained by laser powder bed fusion

Alexis Fouchereau, Beatriz Puga, Hicham Maskrot, Fernando Lomello, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

3D printing by Laser-Powder Bed Fusion (L-PBF) is an innovative process using a high energy density laser to melt the raw material into a powder form. Previous studies have shown that the powder properties are crucial for the density, quality and microstructure of the materials produced [1, 2] but…

Deciphering interfacial capacitance of passive electrode : contribution of the double layer

Oumaïma Gharbi, Mai T.T. Tran, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the EIS response of passive film remains a difficult challenge since it usually results in a non-ideal behavior of the dielectric properties of the film and mainly relies on the assumption that the contribution of the double layer can be neglected. The later an approximation can be…

Antibody-Gold Nanoparticle Bioconjugates for Biosensors: Synthesis, Characterization and Selected Applications

Lu Zhang, Yacine Mazouzi, Michèle Salmain, Bo Liedberg, Souhir Boujday

Antibody-Gold nanoparticle (Ab-AuNP) bioconjugates are widely used in the field of biosensing. This prompted researchers to set up various strategies to conjugate antibodies to gold nanoparticles. Optimal conjugation is of critical importance, as the Ab-AuNP bioconjugates should be stable while…

Ultrafast time-resolved quantum cascade laser diagnostic for enlightening the role of surface formate species in the photocatalytic oxidation of methanol

Josefine Schnee, Marco Daturi, Mohamad El-Roz

In the present work, a new quantum cascade laser (QCL)-assisted operando FT-IR setup was used to get direct insight into the relationship between the overall catalytic performance of TiO2 photocatalysts in the gas phase photooxidation of methanol at 25 °C, and the kinetics of intermediate surface…

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-…

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…

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…

On the kinetics of CO oxidation by O2 over RhI(CO)2 catalytic species anchored to a zeolitic support

Céline Fontaine-Gautrelet, Cyril Thomas, Jean-Marc Krafft, Gérald Djéga-Mariadassou

The reactivity of RhI(CO)2 towards CO oxidation was studied on a model Rh(0.7 wt%)/HY material. The kinetic results show that RhI(CO)2 exhibit a fairly low activity. It is therefore suggested that the catalytic species responsible for the enhanced activity of Rh/Ce0.68Zr0.32O2 [Manuel et al., J.…
