Deciphering the Adsorption Mechanisms of RGD Subunits: L-Aspartic Acid on Cu(110)

Roberta Totani, Christophe Méthivier, Hervé Cruguel, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-Aspartic acid adsorption on a Cu(110) surface. We replaced the traditional sublimation method to obtain molecular films by dosing aspartic acid directly from an aqueous solution through an Electrospray Ionization (ESI) device…

Inelastic light scattering by long narrow gold nanocrystals: when size, shape, crystallinity and assembly matter

Hervé Portalès, Nicolas Goubet, Sandra Casale, Xiang Zhen Xu, Mostapha Ariane, Alain Mermet, Jeremie Margueritat, Lucien Saviot

We report the synthesis of long narrow gold nanocrystals and the study of their vibrational dynamics using inelastic light scattering measurements. Rich experimental spectra are obtained for monodomain gold nanorods and pentagonal twinned bipyramids. Their assignment involves diameter-dependent non…

Plasmonic Properties of Gold Nanostructures on Gold Film

Médéric Lequeux, David Mele, Priyamvada Venugopalan, Raymond Gillibert, Souhir Boujday, Wolfgang Knoll, Jakub Dostalek, Marc Lamy de La Chapelle

This paper reports on a systematic study of the plasmonic properties of periodic arrays of gold cylindrical nanoparticles in contact with a gold thin film. Depending on the gold film thickness, it observes several plasmon bands. Using a simple analytical model, it is able to assign all these modes…

nPEG-TiO2 Nanoparticles: A facile Route to Elaborate Nanostructured surfaces for Biological Applications.

Jolanda Spadavecchia, Souhir Boujday, Jessem Landoulsi, Claire-Marie Pradier

We report the synthesis of diacid-terminated PEG cubic TiO2 nanocrystals by a simple one-step solvothermal method, and their further use to form nanostructured surfaces for protein immobilization. The relevance and major interest of the so-obtained nanocrystals are the presence of terminal…

Surface immobilization mechanisms of cobalt ions on hydroxyapatite catalyst supports

Corentin Reynaud, Cyril Thomas, Dalil Brouri, Yannick Millot, Antoine Miche, Guylène Costentin

Cobalt deposition in an excess of solution was used to design Co-modified hydroxyapatite materials with various Co loadings and controlled dispersion. It is rationalized how the properties of hydroxyapatite supports (more or less stoichiometric compositions, nanorod or platelet morphologies and…

Ionic liquid route for the corrosion inhibition of Al alloys: the effect of butylammonium nitrate on the corrosion of AA2024-T6

Abdelmoheiman Zakaria Benbouzid, Oumaïma Gharbi, Najet Sidi-Yakoub, Mai T T Tran, Mireille Turmine, Vincent Vivier

In this work, the effect of an ammonium nitrate ionic liquid on the corrosion susceptibility of an Al-Cu-Mg alloy was investigated. The effect of the nitrate anion and the ammonium cation on the anodic and cathodic kinetics were studied separately using potentiodynamic polarisation testing,…

Role of Water on the Activity of Magnesium Silicate for Transesterification Reactions

Longfei Lin, Damien Cornu, Maya Mounir daou, Cyril Domingos, Virginie Herledan, Jean-Marc Krafft, Guillaume Laugel, Yannick Millot, Hélène Lauron-Pernot

This study aims to reveal how water adsorbed on to a solid can influence its catalytic properties for transesterification in liquid phase. A commercial magnesium silicate was subjected to a range of thermal pretreatments and used for the transesterification of ethyl acetate with methanol.…
