Application of Arrhenius law to DP and zero-span tensile strength measurements taken on iron gall ink impregnated papers: relevance of artificial ageing protocols

Véronique Rouchon, Oulfa Belhadj, Maroussia Duranton, Alice Gimat, Pascale Massiani

Iron gall inks (IGI) were largely used for writing until the nineteenth century. Under certain circumstances, they provoke a substantial degradation of their cellulosic support.It was shown in a previous works thatc ombination of oxygen and iron largely impacts cellulose chain breaking occurring in…

Corrosion propagation monitoring using electrochemical noise measurements on carbon steel in hydrogenocarbonated solution containing chloride ions

Chloé Comas, François Huet, Kieu Ngo, Marion Fregonese, Hassane Idrissi, Bernard Normand

The propagation of localized corrosion on API 5 L X65 carbon steel in hydrogenocarbonated solution containing chloride ions was monitored during long immersion times by electrochemical noise (EN) measurements in ZRA mode. Monitoring corrosion propagation from the EN amplitude is possible but…

Mesoporous nickel-alumina catalysts derived from MIL-53(Al) metal-organic framework: A new promising path for synthesizing CO2 methanation catalysts

Leila Karam, Maria C Bacariza, José M Lopes, Carlos Henriques, Julien Reboul, Nissrine El Hassan, Pascale Massiani

A new synthesis route for the preparation of highly efficient and stable porous Ni-based alumina catalysts for CO2 methanation is presented. It is based on the use of MIL-53(Al), an Al-containing metal-organic framework (MOF) with high surface area, as sacrificial support. A series of Ni-Al2O3…

Critical assessment of solvent effects on absorption and fluorescence of 3HF in acetonitrile in the QM/PCM framework: A synergic computational and experimental study

Daniele Loco, Stefano Protti, Benedetta Mennucci, Alberto Mezzetti

Absorption and fluorescence properties of 3-hydroxyflavone (3HF) dissolved in the polar aprotic solvent acetonitrile have been investigated by electronic spectroscopies, associated to mixed quantum mechanical (QM)/classical calculations, where the effect of the solvent is included at the classical…

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…

Plasmonic photothermal destruction of uropathogenic E. coli with reduced graphene oxide and core/shell nanocomposites of gold nanorods/reduced graphene oxide

Kostiantyn Turcheniuk, Charles-Henri Hage, Jolanda Spadavecchia, Aritz Yanguas Serrano, Iban Larroulet, Amaia Pesquera, Amaia Zurutuza, Mariano Gonzalez Pisfil, Laurent Heliot, Julie Bouckaert, Rabah Boukherroub, Sabine Szunerits

The development of non-antibiotic based treatments against bacterial infections by Gram-negative uropathogenic E. coli is a complex task. New strategies to treat such infections are thus urgently needed. This report illustrates the development of pegylated reduced graphene oxide nanoparticles (rGO-…

Synthesis of small Ni-core–Au-shell catalytic nanoparticles on TiO2 by galvanic replacement reaction

Julien Reboul, Z. y Li, Jun Yuan, Kazuki Nakatsuka, Masakazu Saito, Kohsuke Mori, Hiromi Yamashita, Yu Xia, Catherine Louis

We report the first preparation of small gold–nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this…

Chemical Differentiation of Planets: A Core Issue

Hervé Toulhoat, Viacheslav Zgonnik

By plotting empirical chemical element abundances on Earth relative to the Sun and normalized to silicon versus their first ionization potentials, we confirm the existence of a correlation reported earlier. To explain this, we develop a model based on principles of statistical physics that predicts…

Intermittent dynamics of bubble dissolution due to interfacial growth of fat crystals

Irma Liascukiene, Gabriel Amselem, Jessem Landoulsi, Deniz Gunes, Charles Baroud

Foams are inherently unstable objects, that age and disappear over time. The main cause of foam aging is Ostwald ripening: smaller air bubbles within the foam empty their gas content into larger ones. One strategy to counter Ostwald ripening consists in creating armored bubbles, where solid…
