BACKGROUND: There is growing interest in soluble biomarkers that could be used on the group level for screening purposes in small proof of principle studies during early drug development. We investigated early changes in serum levels of several candi

This study details thermal reactions between glasses, common minerals, and Trinitite post-detonation material with the fluorinating agent nitrogen trifluoride (NF3). The ultimate goal of our investigation is to develop a relatively rapid method for t

We compare element and isotopic fractionations measured in solar wind samples collected by NASA's Genesis mission with those predicted from models incorporating both the ponderomotive force in the chromosphere and conservation of the first adiabatic

This study reports a comprehensive cross-sectional analysis of major and trace element abundances and 240Pu/239Pu ratios within vertically oriented Trinitite thin sections. The upper glassy layer (~2 mm thick) represents fused desert sand combined wi

This study documents, for the first time, the combined abundances of major and trace elements at high spatial resolution for trinitite glass, which was produced during the first atomic weapon test (Trinity site; New Mexico, USA). The results indicate

The Pb isotopic compositions for 51 spots of melt glass in 11 samples of trinitite have been determined by laser ablation multicollector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS). Trinitite glass yields a large range of Pb isotopic

In the event of a rogue nuclear attack or interception of illicit nuclear materials, timely forensic investigations are critical for accurate source attribution. Uranium (U) and plutonium (Pu) isotopic ratios of intercepted materials or postdetonatio

The activities of 133Ba, 137Cs, 152Eu, 154Eu, 155Eu, 239Pu, and 241Am were determined by gamma spectroscopy on the largest sample set (n = 49) of bulk trinitite to date. The range in activity for all isotopes is large. For example, the activity of 24
