MERCURY DISTRIBUTION BY MICRO PIXE ANALYSIS IN STENOPSYCHE MARMORATA EXPOSED TO MERCURIC CHLORIDE

, 2008
Aquatic insects, such as caddisflies, are used as reference organisms for water pollution. The precise distribution of contaminated metals in the insect, however, remains unknown. In this study, we used micro PIXE analysis to examine mercury distribution

Application of micro-pixe and energy dispersive x-ray microanalytical techniques for localization of nickel within fruits of the Ni-hyperaccumulator Stackhousia tryonii Bailey (Stackhousiaceae)

, 2004
Two micro-analytical techniques, viz. scanning electron microscope-energy dispersive X-ray microanalysis (SEMEDXMA) and micro-PIXE (micro-proton-induced X-ray emission spectrometry), were employed for qualitative and quantitative assessment (respectively)

Micro-PIXE analysis of bioconductive hydroxyapatite coatings on titanium alloy

, 2013
Bioconductive materials and in particular implants using Ti alloy (Ti6–Al4–V) coated with hydroxyapatite (HAp) have proved to be a suitable surgical procedure. However, experience has shown that these implants not always have the required reliability

Micro-SR-XRF and micro-PIXE studies for archaeological gold identification - The case of Carpathian (Transylvanian) gold and of Dacian bracelets

, 2008
Trace-elements are more significant for provenancing archaeological metallic artifacts than the main components. For gold, the most promising elements are platinum group elements (PGE), Sn, Te, Sb, Hg and Pb.

Speciation of lead in ambient air dust combining individual particle analysis by ESEM-EDS, micro-Raman, micro-PIXE and bulk analysis by ICP-MS and selective chemical extractions

, 2003
In order to determine the speciation of lead in ambient air dust, a combination of two complementary levels of investigation is used. The first one consists in a quantitative bulk analysis of the samples by applying selective chemical extractions ...
