NCI : looking at solute/solvent interactions

Robin Chaudret, C. Narth, Raphaël Lugo, Pascal Mougin, Jean-Charles de Hemptinne, Hervé Toulhoat, J. Contreras-García

Understanding solvation interactions is a key problem for many industrial fields: from pharmaceutical to material sciences. From a quantum mechanical viewpoint, two main difficulties arise: firstly, solvation takes place through weak interactions (hydrogen bonds, van der Waals interactions), which…

Chemical nature and thermal decomposition behavior of tartaric acid multilayers on rutile TiO 2 (110)

Elisa Meriggio, Rémi Lazzari, Christophe Méthivier, Pascal David, Stéphane Chenot, Xavier Carrier, Gregory Cabailh, Vincent Humblot

R,R-tartaric acid (RR-TA) thermal stability and decomposition on the rutile TiO2(110) surface was investigated by temperature programmed desorption. The authors show that a majority of RR-TA molecules are desorbed intact from multilayers at around 340 K, while they decompose from the first…

New routes of preparation of active and stable mesoporous Ni-alumina based catalysts for methane dry reforming and CO2 methanation, Nouvelles voies de préparation de catalyseurs actifs et stables à base de Ni-alumine mésoporeuse pour le reformage à sec du méthane et la méthanation du CO2

Leila Karam

Dry reforming of methane (DRM) is a process that converts CH4 and CO2 gases into syngas, a gaseous mixture of H2 and CO. Ni based catalysts proved to be suitable for the reaction due to their good activity, wider availability and lower cost than noble-based materials. However, these catalysts are…, Le reformage à sec du méthane (DRM) est un processus qui convertit simultanément CH4 et CO2 en un mélange gazeux de H2 et de CO appelé syngas. Les catalyseurs à base de Ni sont particulièrement prometteurs mais ils ne sont pas stables en raison du frittage du Ni et du dépôt de coke. Dans cette…

Surface characterizations to investigate osteoarticular mesenchymal tissues : new insights to monitor the extracellular matrix remodeling at the supramolecular level, Caractérisations de surface pour étudier les tissus mésenchymateux ostéoarticulaires : nouvelles perspectives pour surveiller le remodelage de la matrice extracellulaire au niveau supramoléculaire

Ilhem Lilia Jaabar

A connective tissue is a cooperative set of differentiated cells entangled in an extracellular matrix (ECM). The latter, which is particularly abundant, is composed mainly of proteins, such as collagens, and a viscous gel made up of water and negatively charged polysaccharides: proteoglycans. All…, Un tissu conjonctif est un ensemble coopératif de cellules différenciées enchevêtrées dans une matrice extracellulaire (ECM). Cette dernière, particulièrement abondante, se compose principalement de protéines, telles que les collagènes, et d'un gel visqueux constitué d'eau et de…

Crystalline Molybdenum Oxide Thin-Films for Application as Interfacial Layers in Optoelectronic Devices

André Luis Fernandes Cauduro, Roberto dos Reis, Gong Chen, Andreas K. Schmid, Christophe Méthivier, Horst-Günter Rubahn, Léo Bossard-Giannesini, Hervé Cruguel, Nadine Witkowski, Morten Madsen

The ability to control the interfacial properties in metal-oxide thin films through surface defect engineering is vital to fine tune their optoelectronic properties and thus their integration in novel optoelectronic devices. This is exemplified in photovoltaic devices based on organic, inorganic or…

Insights into OCP Identification and Quantification in the Context of Apatite Biomineralization

Marc Robin, Stanislaw von Euw, Guillaume Renaudin, Sandrine Gomes, Jean-Marc Krafft, Nadine Nassif, Thierry Azaïs, Guylene Costentin

Calcium phosphates (CaPs) are one of the major mineral families of wide interest in biomineralization and biomaterial development. The identification and quantification of the different CaP phases (crystalline and amorphous) remains a major challenge in both in vitro and in vivo systems. This work…

Production and Characterization of Activated Carbon from Orange Peels by Chemical Activation with Sulfuric Acid

Sami Guiza, Salwa Hajyahia, Franck Launay, Mohamed Bagane

Oranges represent 75% of the total citrus fruits (Guiza in Ecol Eng, 99: 134–140, 2017) throughout the world, and Tunisia is one of the major juice producers. Orange peels could cause a significant disposal problem but they are also valuable biomass wastes (Valdes et al. in Langmuir 18: 2111–2116,…
