New ammonium surfactant-stabilized rhodium(0) colloidal suspensions: influence of novel counter-anions on physico-chemical and catalytic properties.

Elodie Bile Guyonnet, Rita Sassine, Audrey Denicourt-Nowicki, Franck Launay, Alain Roucoux

Novel anionic species, such as hydrogen carbonate (HCO(3)(−)), fluoride (F(−)), triflate (CF(3)SO(3)(−)), tetrafluoroborate (BF(4)(−)) and chloride (Cl(−)) were investigated as new partners of water soluble N,N-dimethyl-N-cetyl-N-(2-hydroxyethyl) ammonium salts, used as a protective agent of…

Controlled synthesis of copper oxide nanoparticles (CuONPs) by the precipitation method and proposition of their growth mechanism

Fadoua Sallem, Corinne Chanéac, Mickael Wagner, Nicolas Rataj, Eloise Annabi, Alain Castillo, Ludovic Menjot, Astrid Avellan

This study presents an investigation into the surfactant-free synthesis of copper oxide nanoparticles (CuONPs) via a precipitation method, focusing on how various experimental parameters influence nanoparticle characteristics. By varying key parameters, such as precursor type and concentration, pH,…

Insight into the mechanism of action of temporin-SHa, a new broad-spectrum antiparasitic and antibacterial agent

Zahid Raja, Sonia André, Feten Abbassi, Vincent Humblot, Olivier Lequin, Tahar Bouceba, Isabelle Correia, Sandra Casale, Thierry Foulon, Denis Sereno, Bruno Oury, Ali Ladram

Antimicrobial peptides (AMPs) are promising drugs to kill resistant pathogens. In contrast to bacteria, protozoan parasites, such as Leishmania, were little studied. Therefore, the antiparasitic mechanism of AMPs is still unclear. In this study, we sought to get further insight into this mechanism…

Control of the anisotropic shape of cobalt nanorods in the liquid phase: from experiment to theory… and back

Kahina Aït Atmane, Carine Michel, Jean-Yves Piquemal, Philippe Sautet, Patricia Beaunier, Marion Giraud, Mickaël Sicard, Sophie Nowak, Rémi Losno, G. Viau

The polyol process is one of the few methods allowing the preparation of metal nanoparticles in solution. Hexagonal close packed monocrystalline Co nanorods are easily obtained in basic 1,2-butanediol at 448 K after a few minutes using a Co(II) dicarboxylate precursor. By using a combined…

Two- and Four-Electrode Configurations for Contactless Reinforced Concrete Corrosion Monitoring

B. Díaz, X.R. Nóvoa, C. Pérez, A. Pintos, Vincent Vivier

The paper addresses the need for a fast and reliable method for field monitoring reinforced concrete structures. A proof of concept is presented where a noncontact procedure provides quantitative information on the concrete resistivity and reinforcement corrosion rate. A Wenner-type probe is…

The controlled synthesis of metal-acid bifunctional catalysts: Selective Pt deposition and nanoparticle synthesis on amorphous aluminosilicates

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

The rational synthesis of metal-acid bifunctional catalysts based on aluminosilicates will involve control over which domain – alumina or silica – the metal can be deposited on, as well as the control of particle size. These factors determine the ratio and proximity of the metal and acid sites. The…

A Material Perspective on HgTe Nanocrystal-based Short Wave Infrared Focal Plane Arrays

Huichen Zhang, Rodolphe Alchaar, Yoann Prado, Adrien Khalili, Charlie Gréboval, Mariarosa Cavallo, Erwan Bossavit, Corentin Dabard, Tung Huu Dang, Claire Abadie, Christophe Methivier, David Darson, Victor Parahyba, Pierre Potet, Julien Ramade, Mathieu Silly, James Utterback, Debora Pierucci, Sandrine Ithurria, Emmanuel Lhuillier

After the use of nanocrystals as light down-converters, infrared sensing appears to be one of the first market applications where they can be used while being both electrically and optically active. Over recent years, tremendous progress has been achieved, leading to an apparent rise in the…
