Controlling the reproducibility of Coulomb blockade phenomena for gold nanoparticles on an organic monolayer/silicon system

L Caillard, S Sattayaporn, A-F Lamic-Humblot, S Casale, P Campbell, y J Chabal, Olivier Pluchery

Two types of highly ordered organic layers were prepared on silicon modified with an amine termination for binding gold nanoparticles (AuNPs). These two grafted organic monolayers (GOMs), consisting of alkyl chains with seven or 11 carbon atoms, were grafted on oxide-free Si(111) surfaces as tunnel…

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…

Revisiting the Mukaiyama-type epoxidation for the conversion of styrene into styrene carbonate in the presence of O 2 and CO 2

Matthieu Balas, Asma Mayoufi, Richard Villanneau, Franck Launay

Since its first report in the early 1990s, Mukaiyama-type aerobic epoxidation involving the presence of an aldehyde as an electron donor is considered as an interesting oxidation reaction. Among the various metal catalysts efficient for this process, salen-type complexes have many advantages: i)…

Design of simple salophen chromium complexes for a two-steps oxidative carboxylation of styrene with CO2 and O2

Matthieu Balas, Richard Villanneau, Franck Launay

In this work, chromium(III) Salophen complexes bearing tertiary dimethyl or diethyl amino substituents were synthesized and tested as homogeneous co-catalysts associated with n-Bu 4 NBr for the cycloaddition of CO 2 on styrene epoxide under 11 bar of CO 2. Full conversion of styrene oxide into…

Identification and Location of Iron Species in Fe/SBA-15 Catalysts: Interest for Catalytic Fenton Reactions

Cécile Cornu, Jean-Luc Bonardet, Sandra Casale, Anne Davidson, Sebastien Abramson, Gilles André, Florence Porchet, Ivana Grcic, Vesna Tomasic, Dinko Vujevic

We have used a single SBA-15 silica batch (mesopore diameter of 7.1 nm) and the two-solvent impregnation technique with either pentane or cyclohexane to prepare model samples in which an initial aqueous solution of salt precursor (iron nitrate or iron chloride) is deposited mainly inside silica…

The Synthesis of Different Series of Cobalt BEA Zeolite Catalysts by Post-Synthesis Methods and Their Characterization

Renata Sadek, Karolina Chalupka-Spiewak, Jean-Marc Krafft, Yannick Millot, Laetitia Valentin, Sandra Casale, Jacek Gurgul, Stanislaw Dzwigaj

Three series of zeolite catalysts Co all-silica and Co Al-containing zeolites beta were prepared for use in the selective oxidative dehydrogenation of propane to propylene. Two series of zeolite catalysts Co all-silica were prepared by a two-step postsynthesis method at pH = 2.5 and pH = 3.0-9.0,…

Influence of Large Magnetic Field Gradients at the Electrochemical Interface

Jinu Kurian, Peter Dunne, Vincent Vivier, Gwenael Atcheson, Ruslan Salikhov, Ciaran Fowley, Munuswamy Venkatesan, Olav Hellwig, Michael Coey, Bernard Doudin

We investigate how a model single-electron-exchange electrochemical reaction can be influenced by a magnetic field, B, which is a combination of an external applied field and the stray field generated by a Co/Pt multilayer thin film stack with preferred perpendicular magnetization. The Lorentz…

Theoretical and experimental study of the adsorption of neutral glycine on silica from the gas phase

Claire Lomenech, Gregoire Bery, Dominique Costa, Lorenzo Stievano, Jean-François Lambert

The adsorption of neutral glycine onto amorphous silica was investigated both theoretically and experimentally. DFT calculations were performed at the BLYP-631++G** level using a cluster approach. Several possible configurations involving the formation of H-bonds between glycine and one, two or…

Comprehension of cellulose depolymerisation mechanisms induced by iron ions, Compréhension des mécanismes de dépolymérisation de la cellulose induits par les ions fer

Alice Gimat

Degradation of paper by iron gall inks (IGI) is a challenging issue for written heritage conservation. These inks consist of a mixture of iron(II) sulphate, tannins and gum Arabic, and are therefore acidic and iron-rich. Hence, paper degradation by IGI is often attributed to a combination of acid…, La dégradation du papier par les encres ferrogalliques (EFG) est un défi pour la conservation du patrimoine écrit. Ces encres, composées d'un mélange de sulfate de fer (II), de tannins et de gomme Arabique, sont acides et riches en fer. Par conséquent, les mécanismes de dégradation des…
