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,…

Supramolecular Self‐Assembly and Organization of Collagen at Solid/Liquid Interface: Effect of Spheroid‐ and Rod‐Shaped TiO 2 Nanocrystals

Mathieu Beauvais, Thomas Degabriel, Nesrine Aissaoui, Vincent Dupres, Elodie Colaço, Karim El Kirat, Rute F Domingos, Dalil Brouri, Claire‐marie Pradier, Jolanda Spadavecchia, Jessem Landoulsi

The adsorption behavior of collagen on solid surfaces is a process that determines the role of this protein to mediate cell–material interaction. Herein, the mechanism of self‐assembly and organization of collagen on a model substrate is investigated in the presence of TiO2 nanoparticles. In…

Leucine on Silica: A Combined Experimental and Modeling Study of a System Relevant for Origins of Life, and the Role of Water Coadsorption

Hagop Abadian, Pauline Cornette, Dominique Costa, Alberto Mezzetti, Christel Gervais, Jean-François Lambert

Leucine on silica constitutes an interesting system from the point of view of origins of life studies since leucine coadsorbed on SiO2 together with glutamic acid can give rise to rather long linear polypeptides upon activation. It is also an ideal system to test methods of molecular…

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…

An easy way to obtain thin gold film on silica glass substrate by chemical method

Anne-Félicie Lamic-Humblot, Sandra Casale, Cédric Leger, S. Alpérine, Catherine Louis

Physical methods of metal deposition under ultra-high vacuum conditions are currently used to manufacture electrically conductive surfaces. In the case of silica glass, a supplementary oxide layer is usually required to avoid the uncontrolled growth of metal nanoparticles on the surface. Here, we…

Mononuclear pseudo-tetrahedral V species of VSiBEA zeolite as the active sites of the selective oxidative dehydrogenation of propane

Karolina Chalupka, Cyril Thomas, Yannick Millot, Frédéric Averseng, Stanislaw Dzwigaj

This work reports on the investigation of the influence of the nature of the V species in the ODH of propane. For this purpose, VSiBEA catalysts, including framework and/or extra-framework V species, were synthesized via the two-step method by controlling the speciation of the V species of the…

Bimetallic Au-Pd catalysts for selective hydrogenation of butadiene: Influence of the preparation method on catalytic properties

N. El Kolli, L. Delannoy, C. Louis

Supported Au catalysts modified by the addition of small amount of Pd (Au/Pd atomic ratio (10) were prepared according to three different methods, co-deposition-precipitation with urea (DPU), deposition of colloids stabilised either by polyvinyl alcohol (PVA) or by tetrakis (hydroxypropyl)…

Bimetallic Phosphide (Ni,Cu) 2 P Nanoparticles by Inward Phosphorus Migration and Outward Copper Migration

Anh-Minh Nguyen, Mounib Bahri, Sébastien Dreyfuss, Simona Moldovan, Antoine Miche, Christophe Méthivier, Ovidiu Ersen, Nicolas Mézailles, Sophie Carenco

Bimetallic phosphide nanoparticles are drawing a great interest as a family of nanomaterials. Controlling their fine features such as surface composition, core crystal structure and overall composition is a key to further application. Copper and nickel are particularly interesting first-raw metals…
