Characterization of Phosphate Species on Hydrated Anatase TiO2 Surfaces

Frederik Tielens, Christel Gervais, Géraldine Deroy, Maguy Jaber, Lorenzo Stievano, Cristina Coelho Diogo, Jean-Francois Lambert

The adsorption/interaction of KH2PO4 with solvated (100) and (101) TiO2 anatase surfaces is investigated using periodic DFT calculations in combination with GIPAW NMR calculations and experimental IR and solid state 17O, and 31P NMR spectroscopies. A complete and realistic model has been used to…

Assessing carbon or tungstates coverage of ZrO2 nanoparticles supported on MWCNT via NOx-TPD

Patrick Kelleher, Gary Haller, Sandra Casale, Christophe Méthivier, Cyril Thomas

Multi-walled carbon nanotubes (MWCNT) promoted by oxides, that are far from trivial to characterize, have emerged as promising candidates in several fields such as biosensors and catalysis. In this study the coverage of ZrO2 nanoparticles supported on MWCNT, by carbonaceous deposits or tungstates…

Cyto- and bio-compatibility assessment of plasma-treated polyvinylidene fluoride scaffolds for cardiac tissue engineering

Maria Kitsara, Gaëlle Revet, Jean-Sébastien Vartanian-Grimaldi, Alexandre Simon, Mathilde Minguy, Antoine Miche, Vincent Humblot, Thierry Dufour, Onnik Agbulut

As part of applications dealing with cardiovascular tissue engineering, drop-cast polyvinylidene fluoride (PVDF) scaffolds have been treated by cold plasma to enhance their adherence to cardiac cells. The scaffolds were treated in a dielectric barrier device where cold plasma was generated in a…

A New Antibacterial N -Halamine Coating Based on Polydopamine

Nadia Nazi, Vincent Humblot, Catherine Debiemme

To prevent the formation of biofilms on material surfaces, the latter must have antibacterial properties. The aim of this study is to investigate the synthesis and the antibacterial effect of a new N-halamine coating based on polydopamine (PDA). The benefits of this coating are multiple, notably…

Real-time monitoring of Ti-Nb-Ta-Zr and commercially pure Ti interaction with H2O2 using atomic force microscopy and atomic emission spectroelectrochemistry

Agata Sotniczuk, Baojie Dou, Yangping Liu, Oumaïma Gharbi, Fan Sun, Halina Garbacz, Jeremy Gilbert, Kevin Ogle

This study offers a new approach to analyze surface behavior of titanium biomaterials during their exposure to the H2O2-enriched fluid which simulates post-operative inflammatory conditions. In this work in situ AFM and AESEC tests were exploited to study the origin of initial inflammatory-induced…

Defect-related multicolour emissions in ZnO tetrapods: from violet, over green to yellow

Miao Zhang, Frédéric Averseng, Francia Haque, Patrizia Borghetti, Jean-Marc Krafft, Benoît Baptiste, Guylène Costentin, Slavica Stankic

The nature of defects in ZnO smoke was studied at different stages of the materials' history by combining photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopies. In contrast to studies previously reported on ZnO nanopowders, high vacuum conditions (P < 10-5 mbar)…

Approche expérimentale et théorique de l'inhibition de corrosion de surfaces métalliques, Experimental and theoretical approach of corrosion inhibition of metallic surfaces

Pauline Cornette

La corrosion des surfaces d’aluminium et d’alliages aluminium/cuivre, et notamment la corrosion localisée, est un problème majeur dans l’industrie, et l’utilisation d’inhibiteur de corrosion est bien souvent indispensable. Les chromates remplissent parfaitement leurs rôles d’inhibition mais seront…, Corrosion of aluminum and aluminum/copper alloy surfaces, including localized corrosion, is a major problem in the industry, and the use of a corrosion inhibitor is often essential. Chromates perfectly fulfill their role of inhibition but will soon be prohibited because of their toxicities for…

The antibacterial activity of Magainin I immobilized onto mixed thiols Self-Assembled Monolayers

Vincent Humblot, Jean-Fabrice Yala, Pascal Thebault, Kada Boukerma, Arnaud Héquet, Jean-Marc Berjeaud, Claire-Marie Pradier

An antibacterial peptide, Magainin I, was covalently bound to a mixed 11-mercaptoundecanoïc acid (MUA) and 6-mercaptohexanol (C6OH) (ratio 1:3) Self-Assembled Monolayer (SAM) on gold surfaces. Each step of the surface functionalization was characterized by Polarization Modulation Reflection…

Elaboration, activity and stability of silica-based nitroaromatic sensors

D. Mercier, Franck Pereira, Christophe Méthivier, Pierre Montméat, Lionel Hairault, Claire-Marie Pradier

Functionalized silica-based thin films, modified with hydrophobic groups, were synthesized and used as sensors for nitroaromatic compound (NAC) specific detection. Their performance and behavior, in terms of stability, ageing and regeneration, have been fully characterized by combining chemical…
