Heterogeneous Fenton-like reactions in natural soils and sediments at neutral pH with O2 as oxidant

Elora Bourbon, Frederic Averseng, Thierry Allard, Pierre Le Pape, Sylvie Nélieu, Xavier Carrier, Guillaume Morin, Elodie Guigon, Fulvia Baratelli, Sophie Ayrault

Heterogeneous Fenton-like processes using O2 as oxidant and iron(II) minerals as substrate is a rapidly growing research field with important implications especially for in-situ organic pollutant degradation in natural media. These reactions can be conducted at neutral pH and several minerals are…

Direct quantification of surface coverage of antibody in IgG-Gold nanoparticles conjugates

Lu Zhang, David Hu, Michèle Salmain, Bo Liedberg, Souhir Boujday

It is of paramount importance to be able to accurately quantify surface coverage of antibodies on gold nanoparticles (AuNP) so as to optimise the sensitivity of AuNP-based immunosensors. Herein, we developed a fluorescence-based method to directly quantify rabbit immunoglobulin G (IgG) used as…

Electrospun Poly(ε-caprolactone) Fiber Scaffolds Functionalized by the Covalent Grafting of a Bioactive Polymer: Surface Characterization and Influence on in Vitro Biological Response

Gana Amokrane, Vincent Humblot, Emile Jubeli, Najet Yagoubi, Salah Ramtani, Véronique Migonney, Céline Falentin-Daudré

The purpose of this study is to present the poly(caprolactone) (PCL) functionalization by the covalent grafting of poly(sodium styrene sulfonate) on electrospun scaffolds using the "grafting from" technique and evaluate the effect of the coating and surface wettability on the biological…

Au-Modified Pd catalyst exhibits improved activity and stability for NO direct decomposition

Taha Elgayyar, Josefine Schnee, Alain Tuel, Laurence Burel, Francoise Bosselet, Yves Schuurman, Frederic C Meunier, Laurent Delannoy, Cyril Thomas

The direct decomposition of NO x at moderate temperatures is a challenge because of the poisoning of the surface of noble metals by oxygen, yet the modification of Pd with Au enables obtaining a highly stable catalyst under an O 2-free feed at 450°C. Care was taken to ensure that the reaction was…

Effect of ceria promotion on the catalytic performance of Ni/SBA-16 catalysts for CO 2 methanation

Chao Sun, Patricia Beaunier, Patrick da Costa

The presence of Ce inside the SBA-16 structure promoted the ratio of Ce 3+ and medium basic sites and thus favoured CH 4 formation.

Revisiting the Mukaiyama-type epoxidation for the conversion of styrene into styrene carbonate in the presence of O 2 and CO 2

Matthieu Balas, Asma Mayoufi, Richard Villanneau, Franck Launay

Since its first report in the early 1990s, Mukaiyama-type aerobic epoxidation involving the presence of an aldehyde as an electron donor is considered as an interesting oxidation reaction. Among the various metal catalysts efficient for this process, salen-type complexes have many advantages: i)…

C3-Alkylation of furfural derivatives by continuous flow homogeneous catalysis

Grédy Kiala Kinkutu, Catherine Louis, Myriam Roy, Juliette Blanchard, Julie Oble

The C3-functionalization of furfural using homogeneous ruthenium catalysts requires the preinstallation of an ortho -directing imine group, as well as high temperatures, which did not allow scaling up, at least under batch conditions. In order to design a safer process, we set out to develop a…
