Intensity-energy response function of Al/Cr-K α x-ray photoemission instruments: An inter-laboratory study

David Alamarguy, Damien Aureau, Thierry Conard, Nicolas Gauthier, Frédéric Georgi, Stéphane Guilet, Samar Hajjar-Garreau, Olivier Heintz, Guillaume Monier, Christophe Méthivier, Hervé Montigaud, Samantha Soulé, Olivier Renault, Rémi Lazzari

The question of the intensity-energy response of photoemission spectrometers has been approached through a round-robin involving 13 instruments working with low (Al/Mg-K) and high (Cr-K) energy photon sources. An algorithm based on the analysis of inelastic background previously proposed [S. Guilet…

Total Oxidation of Methane on Oxide and Mixed Oxide Ceria-Containing Catalysts

Marius Stoian, Vincent Rogé, Liliana Lazar, Thomas Maurer, Jacques C Védrine, Ioan-Cezar Marcu, Ioana Fechete

Methane, discovered in 1766 by Alessandro Volta, is an attractive energy source because of its high heat of combustion per mole of carbon dioxide. However, methane is the most abundant hydrocarbon in the atmosphere and is an important greenhouse gas, with a 21-fold greater relative radiative…

Sensing the Charge State of Single Gold Nanoparticles via Work Function Measurements

Yingjie Zhang, Olivier Pluchery, Louis Caillard, Anne-Félicie Lamic-Humblot, Sandra Casale, Yves J. Chabal, Miquel Salmeron

Electrostatic interactions at the nanoscale can lead to novel properties and functionalities that bulk materials and devices do not have. Here we used Kelvin probe force microscopy (KPFM) to study the work function (WF) of gold nanoparticles (NPs) deposited on a Si wafer covered by a monolayer of…

Mechanical properties of nanostructured films with an ultralow volume fraction of hard phase

Marion Chenal, Cyril Véchambre, J.-M. Chenal, Laurent Chazeau, Vincent Humblot, Laurent Bouteiller, Costantino Creton, Jutta Rieger

We demonstrate in this paper how polymerization induced self-assembly (PISA) using RAFT can be used to synthesize very asymmetric but monodisperse poly(acrylic acid)-b-poly(n-butyl acrylate) block copolymers, PAA-b-PBA, with a short PAA block and a long PBA block. In the course of the surfactant-…

A combined experimental and theoretical study of the simultaneous occupation of SIa and SI0 sites in fully dehydrated K-LSX

Hazar Guesmi, Pascale Massiani, Habiba Nouali, Jean-Louis Paillaud

In the case of fully potassium exchanged X and LSX faujasites, it was reported from a single crystal X-ray study on zeolite X and preliminary powder X-ray diffraction (PXRD) study on zeolite LSX that K+ ions can be found concomitantly in both sites I and I' with partial or full occupancy of…

Polyoxometalate nanostructured gold surfaces for sensitive biosensing of benzo[a]pyrene

Dimitri Mercier, Maroua Ben Haddada, Maria Huebner, Dietmar Knopp, Reinhard Niessner, Michèle Salmain, Anna Proust, Souhir Boujday

We report the design of a polyoxometalate-nanostructured immunosensor for benzo[a]pyrene (B[a]P) detection. The organic–inorganic hybrid polyoxometalate (POM) (NBu4)3[PW11O39{(SiC6H4NH2)2O}] carrying two amine functions was covalently attached to a functionalized gold substrate to achieve a…

ZnO oxygen vacancies formation and filling followed by in situ photoluminescence and in situ EPR

C. Drouilly, J.M. Krafft, F. Averseng, S. Casale, Delphine Bazer-Bachi, Céline Chizallet, V. Lecocq, H. Vezin, H. Lauron-Pernot, G. Costentin

Oxygen vacancies of zinc oxide were followed by photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopies. The green PL emission was associated with oxygen vacancies: its intensity is enhanced upon static thermal treatment under inert or under vacuum, whereas it decreases upon…

Electrodeposition of Ni-Co alloys from neat protic ionic liquid: Application to the hydrogen evolution reaction

Yuelin Xie, Antoine Miche, Vincent Vivier, Mireille Turmine

Amorphous and nanocrystalline Ni-Co alloys have been deposited on FTO glass in ethylammonium nitrate (EAN), a protic ionic liquid (PIL). The physicochemical properties of EAN with Ni 2+ and Co 2+ salts have been studied as well as the electrochemical behavior of these metal cations in the PIL in…
