Electrochemical and modelling study of ZrNbO alloys aged under high temperature and high pressure PWR simulated conditions

Duncan Peyret, Damien Kaczorowski, Milan Skocic, Bernard Tribollet, Vincent Vivier

This work proposes a kinetic study of Zirconium alloy when working under controlled temperature and pressure conditions to simulate pressurized water reactor (PWR) conditions. A detailed analysis of the experimental results allowed to describe each time constant observed on the impedance diagrams.…

Copper Zinc Aluminate Synthesized by Sol-Gel Method with Polyacrylic Acid as Catalysts for Glycerol Hydrogenolysis

L. Omar, T. Onfroy, S. Daniele, N. Perret

This study describes the use of novel Cu/ZnO/ZnAl2O4/PAAH (PAAH=polyacrylic acid) hybrid nanomaterials for glycerol hydrogenolysis. Their elaboration by sol-gel process either in one step or in two steps allowed to modulate their structural properties in terms of specific surface area, Lewis…

On the physical properties of mixtures of nitrate salts and protic ionic liquids

Pablo Vallet, Silvia Bouzón-Capelo, Trinidad Méndez-Morales, Víctor Gómez-González, Yago Arosa, Raúl de La Fuente, Elena López-Lago, Julio Rodríguez, Luis Gallego, Juan Parajó, Josefa Salgado, Mireille Turmine, Luisa Segade, Oscar Cabeza, Luis Varela

We report a systematic study of the effect of salt concentration and its cation valence on several equilibrium and transport properties of mixtures of the model protic ionic liquid ethylammonium nitrate with monovalent (LiNO3), divalent (Mg(NO3)2 and Ca(NO3)2), and trivalent (Al(NO3)3) salts. These…

Insights into the accessibility of Zr in Zr/SBA-15 mesoporous silica supports with increasing Zr loadings

Masaru Ogura, Remy Guillet-Nicolas, Dalil Brouri, Sandra Casale, Juliette Blanchard, Katie A. Cychosz, Matthias Thommes, Cyril Thomas

Oxide-promoted SBA-15 materials have been shown to be profitable in a wide variety of catalytic reactions of environmental interest. Zr-SBA-15 materials have been found to be of particular interest in hydrotreating, biomass conversion and Fisher–Tropsch synthesis. In these studies, the…

On the chemistry of the conversion coatings

Oumaïma Gharbi, Kevin Ogle, Junsoo Han

A conversion coating is an inorganic or organic–inorganic hybrid surface film conveying specific desirable functions to a material, formed by a spontaneous reaction between the material and an electrolyte. This chapter reviews the fundamental physical chemistry of the conversion coating process and…

Beyond simple AB diblock copolymers: application of bifunctional and trifunctional RAFT agents to PISA in water

Gaëlle Mellot, Patricia Beaunier, Jean-Michel Guigner, Laurent Bouteiller, Jutta Rieger, François Stoffelbach

The influence of the macro-RAFT agent architecture on the morphology of the self-assemblies obtained by aqueous RAFT dispersion polymerization in PISA is studied by comparing amphiphilic AB diblock, (AB)2 triblock and triarm-star shaped (AB)3 copolymers, constituted of N,N-dimethylacrylamide (DMAc…

Solvent effects on the vibrational spectrum of 3-hydroxyflavone

Ari Paavo Seitsonen, Abdenacer Idrissi, Stefano Protti, Alberto Mezzetti

3-hydroxyflavone (3HF) is a widely studied molecule that acts as a simplified prototype of biological, more complex flavonoids. Its solvation mechanism is still under investigation. Here we report a joint experimental and simulation study of the vibrational properties of 3HF in gas phase and in…
