Accumulation, translocation and impact of TiO2 nanoparticles in wheat (Triticum aestivum spp.): influence of diameter and crystal phase.
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 goodsExpand

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 nonvolatileExpand

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 additivesExpand

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. TheseExpand

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 isExpand

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 simultaneouslyExpand
