We find no physical basis for traditional mass-fraction weighted averaging of X-ray continuum measured in pure elements to estimate continuum production from compounds. Measurements of continuum from pairs of stable isotopes demonstrate that mass alone (the presence of more or fewer neutrons) has no effect on continuum production in electron probe microanalysis. Electron-fraction weighted avera...

The interfacial microstructure and cofiring migration between Ag /Pd electrode and Pb-based relaxor ferroelectric ceramics were directly investigated via transmission electron microscope and energy dispersive X-ray spectroscopy (EDS). Different silver migration abilities of 70Ag /30Pd and 90Ag /10Pd electrodes were confirmed by EDS microanalysis. This difference is generally considered to be re...

Sporocyst walls of the coccidian parasites Aggregata eberthi and A. octopiana, were subjected to semiquantitative x-ray elemental microanalysis. Peaks above background level were obtained for Na, P, S and Si in both species, with also a peak for Ca in A. eberthi which was not detectable in A. octopiana. Whilst the amounts of Na, P and S can be considered similar for both species, the relative p...

This paper described the mechanochemical (solvent free) synthesis and structural analysis of stable copper (II) glutathione complexes. The bluish green copper (II) glutathione complexes were synthesized in mole ratios of 1:2 and 1:4 [(M: L) Metal: Ligand]. Infrared spectroscopy confirmed that copper (II) binding occurred via -SH of thiol. Microanalysis data agrees with the ML in case of 1:2 and...
