Transfer and State Changes of Fluorine at Polytetrafluoroethylene/Titania Boundaries by Mechanical Stressing and Thermal Annealing
Vincent Laporte, Danielle Gomes Passos Silva, Di Wang
Fluorine in polytetrafluoroethylene (PTFE) changes its states and transfers to titania by comilling and annealing of a titania-PTFE mixture. XPS, F-19 MAS NMR, FT-IR. Raman spectra, TEM and EDX analyses consistently indicated the oxidative decomposition of ...
Amer Chemical Soc2013Postpolymerization Modification of Poly(glycidyl methacrylate) Brushes: An XPS Depth-Profiling Study
Harm-Anton Klok, Vincent Laporte, Raphaël Barbey
Surface-initiated polymerization represents a versatile strategy to modify a diverse range of materials with thin, functional polymer coatings. While in many cases the desired functional groups can be directly incorporated via (co)polymerization of the app ...
Amer Chemical Soc2013Characterization of Three Amino-Functionalized Surfaces and Evaluation of Antibody Immobilization for the Multiplex Detection of Tumor Markers Involved in Colorectal Cancer
Vincent Laporte, Nicolas Xanthopoulos
Antibody microarrays are powerful and high-throughput tools for screening and identifying tumor markers from small sample volumes of only a few microliters. Optimization of surface chemistry and spotting conditions are crucial parameters to enhance antibod ...
Amer Chemical Soc2013Effect of Crystallographic Phase (β vs. γ) and Surface Area on Gas Phase Nitroarene Hydrogenation Over Mo2N and Au/Mo2N
Lioubov Kiwi, Vincent Laporte, Fernando Cardenas Lizana, Daniel André Samuel Lamey
The catalytic action of Mo2N and Au/Mo2N has been assessed in the selective gas phase hydrogenation of p-chloronitrobenzene (p-CNB) to p-chloroaniline (p-CAN). The nitrides were synthesised via temperature programmed treatment of MoO3 in H-2 + N-2 and Au i ...
Springer US2012Modification of titania nanoparticles for photocatalytic antibacterial activity via a colloidal route with glycine and subsequent annealing
César Pulgarin, Paul Bowen, Vincent Laporte, Oualid Baghriche, Nicholas Myers
Changes in the colloid-chemical and photocatalytic properties of titania nanoparticles by attrition milling in the presence of glycine (Gly) and subsequent heat treatment were examined. By milling at 1500 rpm for 6 h, the average particle size was decrease ...
Cambridge Univ Press2012Introduction of oxygen vacancies and fluorine into TiO2 nanoparticles by co-milling with PTFE
Vincent Laporte, Benjamin Bauer
Solid-state processes of introducing oxygen vacancies and transference of fluorine to n-TiO2 nanoparticles by co-milling with poly(tetrafluoroethylene) (PTFE) powder were examined by diffuse reflectance spectroscopy (DRS) of UV, visual, near- and mid-IR re ...
2012TaOxNy Sputtered Photoanodes For Solar Water Splitting
Michael Graetzel, Kevin Sivula, Vincent Laporte, Rosendo Sanjines, Nicolas Xanthopoulos, Maurin Cornuz
A series of TaOxNy photoelectrodes were deposited on F:SnO2 (FTO) substrates by DC reactive sputtering at room temperature, under a mixture of Ar, N-2 and O-2. The effects of the O-2 partial pressure during deposition (Po-2) on the films crystallinity, the ...
Elsevier Science Bv2012Surface Functionalisation of Alumina Ceramic Foams with Organic Ligands
Sandrine Gerber, Vincent Laporte, Pascal Miéville, Françoise Borcard, Marc Anthony Caporini
Different anchoring groups have been studied with the aim of covalently binding organic linkers to the surface of alumina ceramic foams. The results suggested that a higher degree of functionalisation was achieved with a pyrogallol derivative - as compared ...
2012Low-Temperature Preparation of Tailored Carbon Nanostructures in Water
Anna Fontcuberta i Morral, Holger Frauenrath, Vincent Laporte, Davide Demurtas, Bernt Ketterer, Tobias Hoheisel, Ruth Szilluweit, Martin Fritzsche, Raffaele Mezzenga
The development of low-temperature carbonization procedures promises to provide novel nanostructured carbon materials that are of high current interest in materials science and technology. Here, we report a "wet-chemical" carbonization method that utilizes ...
American Chemical Society2012Reducing recombination in ZnO photoanodes for dye sensitised solar cells through simple chemical synthesis
Michael Graetzel, Vincent Laporte, Lioz Etgar
A method has been developed to synthesise zinc oxide nanowire arrays that demonstrate superior device performance compared to conventional ZnO nanowires within dye sensitised solar cells (DSSCs). This simple yet effective methodology has produced nanowires ...
