Abstract In this work, we demonstrate the feasibility of quantitative laser-based x-ray fluorescence (XRF) combined with particle-induced emission (PIXE) (called XPIF for and fluorescence) spectroscopy analysis elemental composition in solid samples. A multi-hundred TW laser system accelerated protons produced x-rays that were impinging on samples, inducing characteristic line emissions element...

The application of scanning nuclear microprobe for study a radiation-induced migration of impurities at the grain boundaries in structural materials was considered. The work describes the sample preparation for a further irradiation of microscopic areas which include a few grains. Copper samples with deposited sulfur film were used in the present work. Determinations of a chemical composition o...

Although glass is usually considered as a very stable archaeological material, it can undergo severe degradation. Soda-lime glass, the most common glass throughout ancient times, is particularly sensitive to this problem. The glass surface absorbs moisture from its environment and the contact with CO2 causes Na2O and NaOH to convert to Na2CO3, which is extremely hygroscopic. The subsequent unst...

This study was carried out to describe the chemical characteristics of individual residual particles in hexagonal snow crystals, which can provide a clue to the aerosol removal mechanism during snowfall. In the present study, to collect snow crystal individually and to identify the elemental composition of individual residues retained in a hexagonal crystal, an orchestration of the replication ...

A novel in-air PIXE (Particle Induced X-ray Emission) setup was developed which is capable of the fast, sensitive, fully quantitative characterization elemental composition thin and thick samples for elements with Z > 6.

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...
