Michèle Salmain, Mahsa Ghasemi, Souhir Boujday, Jolanda Spadavecchia, Marie-Clarisse Techer, Florence Val, Vincent Le Moigne, M. Gautier, Romain Briandet, Claire-Marie Pradier

A direct, label-free immunosensor was designed for the rapiddetection and quantification of staphylococcal enterotoxin A (SEA) in buffered solutions using quartz crystal microbalance with dissipation (QCM-D) as transduction method. The sensing layer including the anti-SEA antibody was constructed…

Synthesis of supported ZSM-5 nanoparticles

Olfa Ben Moussa, Ilef Borghol, David Hu, Sandra Casale, Yannick Millot, Celine Sayag, Juliette Blanchard, Olivier Durupthy

The influence of the support on the nucleation of ZSM-5 nanoparticles has been studied for three supports: γ-alumina, zirconia and carbon nanotubes (CNT). While zeolite nucleation was suppressed in presence of alumina and strongly delayed in presence of zirconia, it occurred without delay in…

Atomic level characterization and sulfur resistance of unsupported W2C during dibenzothiophene hydrodesulfurization. Classical kinetic simulation of the reaction

Marek Lewandowski, Agnieszka Szymanska-Kolasa, Céline Sayag, Patricia Beaunier, Gérald Djéga-Mariadassou

The stability of unsupported W2C tungsten carbide and its sulfur resistance during hydrodesulfurization (HDS) of dibenzothiophene (DBT) are a specificity of W2C. This material was characterized by X-ray diffraction, specific surface area measurements, HRTEM associated with EDS, lattice images,…

Halochromic modulation of amorphous calcium carbonate crystallization driven by pH-responsive bioinspired pigments

Vaskar Sardhalia, Claudio dos Reis Ferreira, Guillaume Laurent, Mohamed Selmane, Anne Vallée, Mathieu Frégnaux, Xiaoyan Li, Marta de Frutos, Andrew Fitch, Clemens Schmitt, Shahrouz Amini, Zhaoyong Zou, Iryna Polishchuk, Boaz Pokroy, Peter Fratzl, Thierry Azaïs, Nadine Nassif, Marie Albéric

Abstract Colors in biominerals often arise from the occlusion of low-molecular-weight organic pigments within calcium carbonate (CaCO 3 ) mineral phases during biomineralization processes; however, the physicochemical origin of these colors has been overlooked. Here, inspired by the growth of…

A common precursor to both prebiotic and biological pathways to RNA nucleotides

Andrea Pérez-Villa, Thomas Georgelin, Jean-François Lambert, Marie-Christine Maurel, François Guyot, A. Marco Saitta, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-D-ribose-1-diphosphate (α-PRPP) and nucleobases.…

Microwave bentonite silylation for dye removal: Influence of the solvent

Líbia N.F. Queiroga, Mariana B.B. Pereira, Lucinaldo Silva, Edson Silva Filho, Ieda M.G. Santos, Maria Fonseca, Thomas Georgelin, Maguy Jaber

A series of bentonite silylated samples was prepared with aminopropyltrimethoxy silane over a short period of time (5 min), at 50 °C, using microwave irradiation. The influence of polar and non-polar solvents was investigated. The pristine and modified solids were characterized by structural,…

Unsupported shaped cobalt nanoparticles as efficient and recyclable catalysts for the solvent-free acceptorless dehydrogenation of alcohols

Arnaud Viola, Jennifer Péron, Kamila Kazmierczak, Marion Giraud, Carine Michel, Lorette Sicard, Noémie Perret, Patricia Beaunier, Mickaël Sicard, Michele Besson, Jean-Yves Piquemal

Oxidation of alcohols is a key-reaction for the valorization of biomass compounds, and green processes are preferred to avoid the use or production of toxic compounds. In this context, unsupported nanometer-sized catalysts have emerged as very promising materials for heterogeneous catalysis. In…

Phosphorylation of a conserved serine in the deoxyribonucleic acid binding domain of nuclear receptors alters intracellular localization.

Kai Sun, Vedrana Montana, Karthikeyani Chellappa, Yann Brelivet, Dino Moras, Yutaka Maeda, Vladimir Parpura, Bryce M Paschal, Frances M Sladek

Nuclear receptors (NRs) are a superfamily of transcription factors whose genomic functions are known to be activated by lipophilic ligands, but little is known about how to deactivate them or how to turn on their nongenomic functions. One obvious mechanism is to alter the nuclear localization of…
