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 concentration of tr...

ABSTRACT  BACKGROUND: PIXE (Particle Induced X-Ray Emission) is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. It is very important to know which factors or probably elements act as initial seed and lead to growing the sands. The goal of this study was to compare the relative values of Fe/K, Cu/K and Zn/K for gallst...

The properties of many biological materials often depend on the spatial distribution and concentration of the trace elements present in a matrix. Scientists have over the years tried various techniques including classical physical and chemical analyzing techniques each with relative level of accuracy. However, with the development of spatially sensitive submicron beams, the nuclear microprobe t...

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.
