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…

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…

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…

Redox-Triggered Control of Cell Adhesion and Deadhesion on Poly(lysine)- g -poly(ethylene oxide) Adlayers

Louise Hespel, Julien Dupré de Baubigny, Pierre Lalanne, Simon de Beco, Mathieu Coppey, Catherine Villard, Vincent Humblot, Emmanuelle Marie, Christophe Tribet

Spontaneous adsorption of poly(lysine)-g-poly(ethyleneglycol) comb-like copolymers (PLL-g-PEG) is a versatile mean to coat substrates with polymer layers that resist cell adhesion. We prepared redox cleavable PLL-g-PEG to switch adhesion on demand. Redox sensitivity was obtained by introducing…

Basic Cs-Pt/MCM-41 Catalysts: Synthesis, Characterization and Activity in n-Hexane Conversion

J. Blanchard, Katia Fajerwerg, M. Breysse, P. Beaunier, M.F. Ribeiro, J.M. Silva, P. Massiani

Cs-Pt/MCM-41 catalysts with basic character have been prepared by selective adsorption of Pt(NH3)4(OH)2 at pH = 8 on pure silica MCM-41 followed by incipient-wetness impregnation of CsNO3, then oxidation and reduction. The influence of the amount of Cs (0, 2 and 4 wt%) on the size of the reduced Pt…
