Intensive production of TiO(2) nanoparticles (TiO(2)-NPs) would lead to their release in the environment. Their ecotoxicological impact is still poorly documented, while their use in commercial goods… Expand
Comet 81P/Wild 2 Under a Microscope
The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study. The preliminary examination of these samples shows that the nonvolatile… Expand
Concentration and distribution of cobalt in higher plants: The use of micro-PIXE spectroscopy
Abstract Cobalt is not classified as an essential element for plants, however, it is usually described as “beneficial”. This trace element can be a contaminant in soils due to agricultural additives… Expand
Calibration of the infrared molar absorption coefficients for H in olivine, clinopyroxene and rhyolitic glass by elastic recoil detection analysis
Abstract We use a nuclear microbeam technique (Elastic Recoil Detection Analysis or ERDA) to measure the H content in 2 rhyolitic glasses, 4 olivines, 4 orthopyroxenes, and 7 clinopyroxenes. These… Expand
The Pierre Süe Laboratory nuclear microprobe as a multi-disciplinary analysis tool
Abstract The nuclear microprobe at the Pierre Sue Laboratory is a facility exclusively devoted to microanalysis. The microprobe consisting of a single stage Van de Graaff accelerator and two… Expand

We synthesized aligned multiwalled carbon nanotube multilayers by aerosol-assisted catalytic chemical vapor deposition through sequential injections of aerosols containing both carbon and catalyst… Expand
Determination of hydrogen content in geological samples using elastic recoil detection analysis (ERDA)
Abstract The present study illustrates the interest of using the elastic recoil detection analysis (ERDA) method to characterize any geological sample matrix with respect to hydrogen. ERDA is… Expand
Development of “position–charge–time” tagged spectrometry for ion beam microanalysis
Abstract During sample analysis in scanning mode, our PC-based data acquisition system (MPA/PCTM) is able to record eight parameter events in a list data file. The system can acquire simultaneously… Expand

Uranium is a naturally occurring heavy metal. Its extensive use in the nuclear cycle and for military applications has focused attention on its potential health effects. Acute exposures to uranium… Expand
Influence of uranium speciation on its accumulation and translocation in three plant species: Oilseed rape, sunflower and wheat
Chemical speciation greatly influences the accumulation and distribution of metallic pollutants in plants. This study aimed at evaluating plant differential responses to various speciations of a same… Expand
