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...

background: the method of proton induced x-ray emission (pixe) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. the sensitivity of this powerful method is in the order of ppm .the aim of this work is to analyze structural composition of 4 heavy trace elements with z greater than 24 (mn, fe, cu, zn) in two kinds of gallstones and to...

The GUPIX package for processing particle-induced X-ray emission (PIXE) spectra has been updated and expanded, with emphasis on the 1–15 keV energy range accessed by silicon drift detectors. Several portions of database are modified or extended. existing mass attenuation coefficient (MAC) dataset is now partnered an alternative MAC which improves PIXE’s accuracy in analysis light elements. Diff...

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.
