Preliminary results of experiments on D2 gas permeation using a system [vacuum/CaO/Sr/PdD x/D2] have shown some evidence of nuclear transmutation from Sr to Mo. The system is a little simpler than that used by Iwamura et al., and has a reversed gas flow direction. The diagnostic method used to identify the elements was conventional XPS, giving the areal densities of 4.21014 cm-2 (Sr) and 3.31...

Proton induced X-ray emission spectroscopy (PIXE) has been used to determine the intensity of metals from crowns in human teeth. In order to measure elements distribution across the tooth section, proton beam (3 MeV) has been collimeted to provide a spatial resolution of 300 microns. The samples were selected according to the time of insertion of crowns and the kind of alloys they were made of....

The collection of denarii from the time of development of a Polish medieval state was studied using the proton induced X-ray emission spectroscopy. The major elements detected for these denarii are Ag and Cu, while minor elements such as Pb, Fe, Au, Bi, and Zn may also be present. The aim of the study was to cross-compare the results with a previous micro-X-ray fluorescence data and to perform ...

Lichens have been shown to be effective biomonitors of air quality. They are currently being used to characterize background element levels and to identify air pollution effects on federally administered lands in the Rocky Mountain region of the western United States. PIXE analysis for twenty elements has been performed on over two hundred lichen specimens collected from various national forest...

Trace element investigation and its corresponding concentration level in selected tropical woods from western Nigeria was done using PIXE-particle induced X-ray emission methods. Fifteen were analyzed twenty-seventrace elements identified quantified. The trace are Na,Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Br, Rb, Sr, Y, Zr, Ba, Pb Bi. Calcium were2835, 3195, 4923, 5...

PURPOSE The retina and other tissues need iron to survive. However, the normal iron metabolism in rodent retinas had not been characterized. This study was intended to investigate iron and iron homeostasis protein (ferritin, transferrin [Tf] and transferrin receptor [Tf-R]) distribution in 20- to 55-day-old rat retinas. METHODS Iron was revealed on retinal sections directly by proton-induced ...

The metallome has been involved in the pathological investigation into ocular tissue for decades; however, as technologies advance, more information can be ascertained from individual sections that were not previously possible. Herein, a demonstration of complementary techniques utilized to describe distribution and concentrations essential metals both wildtype (WT) rhodopsin (Rho−/−) tissues. ...

Abstract The measurement of trace elements in nails and hairs has advantages relative to other body tissues they have been increasingly used forensic clinical toxicology as a complementary test. Complementary hair nail analysis can indicate the amount for long periods time. In this study, samples were collected from city Hamedan quantitative elemental concentration was measured by PIXE techniqu...
