Trace Metal and Speciation Analysis using Ion-Exchange and Energy Dispersive X-ray Fluorescence Spectrometry
… in trace metal and speciation measurement by EDXRF. Structural information was obtained by scanning electron microscopy and x-ray microanalysis showing a homogeneous distribution of functional groups and retained ions on both sectioned and whole resins. Particle size experiments performed on …

Steward's southern Great Basin research validated through obsidian artifact sources
Energy Dispersive X-Ray Fluorescence (EDXRF) analysis of obsidian artifacts collected from ethnohistoric sites in southern Nevada revealed patterns consistent with Julian Steward's documentation of Western Shoshone socioeconomics. Specific obsidian sources were predicted to be present in artifact …

Effects of physical and chemical properties of bright and dull coal lithotypes on the formation of char particles
… and energy dispersive X-ray fluorescence (EDXRF) analyses were used to characterize each lithotype. A bench-scale pressurized fluidized-bed reactor (PFBR) was used to produce ash and char from the lithotypes. The lithotypes and char were examined with transmission electron microscopy. …
