The X-ray fluorescence spectral qualitative and quantitative analyses were performed for the elemental composition of 4 marks of bullets for pneumatic weapon of home and foreign production, and also for imitators of common clothing materials camouflage fabric and cotton knitwear. It is determined that lead bullets for pneumatic weapons are capable to introduce some elements of their composition, which are inherent in one or another mark of bullets, to the area of damage on certain clothing materials, in particular, camouflage fabric and cotton knitwear. This expands the possibilities of forensic medical examination when dealing with a problem of determining the type and mark of a bullet or of a small group of bullets similar in their elemental composition, due to which the pneumatical shot injuries of examined objects took place.

AbstractSeven ternary mixtures of gold(80-95%)-silver(4-15%)-copper(1-15%) were prepared as standards for the determination of elemental composition by energy dispersive X-ray spectrometry (EDS). Two geometric forms (flat and oblate) of the standards were prepared for comparison to the analyses of historic gold objects. Surface analyses were performed. Polished sections of the standards were also analysed Comparison between two methods for collecting EDS data is reported. The analyses are discussed in terms of developing a generalized methodology for estimating elemental composition of museum artifacts.

In this study, we report a methodology which enables the determination of the degradation mechanisms responsible for catalyst deterioration under different accelerated stress protocols (ASPs) by combining measurements of the electrochemical surface area (ECSA) and Pt content (by X-ray fluorescence).
