New evidence for TiO2 uniform surfaces leading to complete bacterial reduction in the dark: Critical issues

César Pulgarin, Juan Kiwi, Sami Rtimi, Danièle Laub, Jelena Nesic

This study presents new evidence for the events leading to Escherichia coil reduction in the absence of light irradiation on TiO2-polyester (from now on TiO2-PES. By transmission electron microscopy (TEM) the diffusion of TiO2 NP's aggregates with the E. c ...

Combustion synthesis of cadmium sulphide nanomaterials for efficient visible light driven hydrogen production from water

Danièle Laub, Nicolas Xanthopoulos

Anion-doped cadmium sulphide nanomaterials have been synthesized by using combustion method at normal atmospheric conditions. Oxidant/fuel ratios have been optimized in order to obtain CdS with best characteristics. Formation of CdS and size of crystallite ...

Study of new sheep bone and Zn/Ca ratio around TiAlV screw: PIXE-RBS analysis

Philippe Buffat, Danièle Laub

This study reports on in vivo particle induced X-ray emission (PIXE) measurements combined with Rutherford backscattering spectroscopy (RBS) analyses of new remodeled sheep bone formed around TiAIV screws. The implants (screws) were anodized by a modified ...

Photocatalytic discoloration of Methyl Orange on innovative parylene–TiO2 flexible thin films under simulated sunlight

Albert Renken, Lioubov Kiwi, Juan Kiwi, Danièle Laub

Parylene films loaded with TiO2 are reported as hotocatalysts in azo dye discoloration processes. The TiO2 loading of the parylene film was 0.32% (w/w) and the amount of TiO2 on the film was about two orders of magnitude below the TiO2 added in suspension ...

Preparation, stabilization and characterization of TiO2 on thin polyethylene films (LDPE): Photocatalytic applications

Albert Renken, Philippe Buffat, Lioubov Kiwi, Juan Kiwi, Andrzej Kulik, Danièle Laub, Kyumin Lee

An innovative way to fix preformed nanocrystalline TiO2 on low-density polyethylene film (LDPE-TiO2) is presented. The LDPE-TiO2 film was able to mediate the complete photodiscoloration of Orange II using about seven times less catalyst than a TiO2 suspens ...

Accelerated photodegradation (minute range) of the commercial azo-dye Orange II mediated by Co3O4/Raschig rings in the presence of oxone

Lioubov Kiwi, Michaël Bensimon, Danièle Laub

The accelerated discoloration of Orange II by an innovative Co3O4/Raschig ring photocatalyst (from now on Co3O4/RR) is feasible and proceeds to completion using oxone as an oxidant within the surprisingly short time of ∼5 min. The preparation of Co3O4 smal ...

Synthesis of monodispersed palladium nanoparticles to study structure sensitivity of solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol

Albert Renken, Lioubov Kiwi, Danièle Laub

A novel method for isolation of monodispersed Pd nanoparticles from a reverse microemulsion was developed using hydrocarbon evaporation and methanol-assisted particle purification from a surfactant. Fcc Pd nanoparticles of 6, 8, 11, and 13 nm in diameter w ...
