A method based on the refinement of atomic and experimental parameters developed for the description of PIXE spectra is presented and applied to standardless semi-quantitative PIXE analysis. This method was implemented in ...

Total charge deposited by a proton beam in an insulator during PIXE analysis has been indirectly determined using a Mylar film coated with cobalt. Elemental concentrations in the samples, pieces of volcanic glass, were ...

Here, we present the analysis of wood to determine trace elements in tree rings. We have irradiated wood pieces directly, for thick target PIXE, and also thin samples obtained by chemical treatment of the wood material. ...

Fish liver is the primary organ related to the biotransformation of organic contaminants and metals. This organ is very sensitive to organic and inorganic contaminants and can accumulate them in higher amounts relative to ...

Clouds are one of the major limitations to crop monitoring using optical satellite images. Despite all efforts to provide decision-makers with high-quality agricultural statistics, there is still a lack of techniques to ...
