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…

Supramolecular Self‐Assembly and Organization of Collagen at Solid/Liquid Interface: Effect of Spheroid‐ and Rod‐Shaped TiO 2 Nanocrystals

Mathieu Beauvais, Thomas Degabriel, Nesrine Aissaoui, Vincent Dupres, Elodie Colaço, Karim El Kirat, Rute F Domingos, Dalil Brouri, Claire‐marie Pradier, Jolanda Spadavecchia, Jessem Landoulsi

The adsorption behavior of collagen on solid surfaces is a process that determines the role of this protein to mediate cell–material interaction. Herein, the mechanism of self‐assembly and organization of collagen on a model substrate is investigated in the presence of TiO2 nanoparticles. In…

Hollow Gold Nanoshells for Sensitive 2D Plasmonic Sensors

Daoming Sun, Ferdaous Ben Romdhane, Axel Wilson, Michèle Salmain, Souhir Boujday

The interaction of incident light with noble metal nanoparticles engenders a fascinating phenomenon known as localized surface plasmon resonance (LSPR). This results in the presence of single or multiple intense absorption bands in the visible to near-infrared spectral range whose position is…

A straightforward approach to high purity sodium silicide Na4Si4

Yang Song, Isabel Gómez-Recio, Ram Kumar, Cristina Coelho Diogo, Sandra Casale, Isabelle Génois, David Portehault

Sodium silicide Na4Si4 is a reductive and reactive source of silicon highly relevant to designing non-oxidic silicon materials, including clathrates, various silicon allotropes, and metal silicides. Despite the impor-tance of this compound, its production in high amounts and high purity is still a…

Leucine on Silica: A Combined Experimental and Modeling Study of a System Relevant for Origins of Life, and the Role of Water Coadsorption

Hagop Abadian, Pauline Cornette, Dominique Costa, Alberto Mezzetti, Christel Gervais, Jean-François Lambert

Leucine on silica constitutes an interesting system from the point of view of origins of life studies since leucine coadsorbed on SiO2 together with glutamic acid can give rise to rather long linear polypeptides upon activation. It is also an ideal system to test methods of molecular…

Production and Characterization of Activated Carbon from Orange Peels by Chemical Activation with Sulfuric Acid

Sami Guiza, Salwa Hajyahia, Franck Launay, Mohamed Bagane

Oranges represent 75% of the total citrus fruits (Guiza in Ecol Eng, 99: 134–140, 2017) throughout the world, and Tunisia is one of the major juice producers. Orange peels could cause a significant disposal problem but they are also valuable biomass wastes (Valdes et al. in Langmuir 18: 2111–2116,…

Crystalline Molybdenum Oxide Thin-Films for Application as Interfacial Layers in Optoelectronic Devices

André Luis Fernandes Cauduro, Roberto dos Reis, Gong Chen, Andreas K. Schmid, Christophe Méthivier, Horst-Günter Rubahn, Léo Bossard-Giannesini, Hervé Cruguel, Nadine Witkowski, Morten Madsen

The ability to control the interfacial properties in metal-oxide thin films through surface defect engineering is vital to fine tune their optoelectronic properties and thus their integration in novel optoelectronic devices. This is exemplified in photovoltaic devices based on organic, inorganic or…

NCI : looking at solute/solvent interactions

Robin Chaudret, C. Narth, Raphaël Lugo, Pascal Mougin, Jean-Charles de Hemptinne, Hervé Toulhoat, J. Contreras-García

Understanding solvation interactions is a key problem for many industrial fields: from pharmaceutical to material sciences. From a quantum mechanical viewpoint, two main difficulties arise: firstly, solvation takes place through weak interactions (hydrogen bonds, van der Waals interactions), which…

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…

Study of calixarenes thin films as chemical sensors for the detection of explosives

P. Montmeat, F. Veignal, C. Methivier, C.M. Pradier, L. Hairault

Calix(n)arenes (n = 4, 6, 8) are used as sensitive coatings for Quartz Crystal Microbalance (QCM)-based chemical sensors, and specially for the detection of dinitrotoluene as a model explosive molecule. Calix(n)arenes complex organic architectures were deposited by spray on gold-coated wafer…
