Abstract The outputs of the multi-elemental IBA techniques PIXE, PIGE, RBS and PESA have been used as inputs to positive matrix factorisation source apportionment methods quantify fingerprint bushfire smoke during catastrophic black summer bushfires 2019-20 season in NSW, Australia.

Background: Trace elements play an important role in a number of biological processes. Astaxanthin (ASX), a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. This work intended to understand the effect of Astaxanthin in breast cancer (invasive ductal carcinoma, IDC) by using micro-pixe method. For this aim the concentratio...

Background: Proton induced X-ray emission (PIXE) has been applied as reliable and improved techniques in this study to compare concentration of various trace elements in normal and abnormal varicose veins. Materials and Methods: Five samples from normal veins and 13 samples from varicose veins bombarded by 2.0 MeV energy proton beams produced by a Van de Graff accelerator in vacuum. T...

Proton-Induced X-ray Emission analysis (PIXE) constitutes a method for trace element analysis characterized by multielemental capability, detection limits in the low ppm-range and size resolution down towards a micrometre. In applications where the sensitivity of the Electron-Induced X-ray Emission (EIXE) analysis is not sufficient and where a spatial resolution not better than a few micrometre...

Nuclear microprobe at 2 MV Tandetron accelerator of Jozef Stefan Institute (JSI) was constructed in the year 2000 with the support of IAEA Technical Cooperation Project SLO/1/004. The measuring station is equipped with instrumentation for micro-Proton-Induced-X-ray-Emission (micro-PIXE), micro-Elastic Recoil Detection Analysis (micro-ERDA), micro-Nuclear Reaction Analysis (micro-NRA), Proton Be...

A central problem in archaeological research has been the chronometric dating of petroglyphs (rock engravings). Recent improvements in the understanding of the chemistry of rock varnish (or patina) that develops on rock surfaces in arid regions has resulted in the development of a calibrated dating technique, cation-ratio (CR) dating. This is based on calibrating chemical changes in minor and m...
