Incorporation of palladium into pyrite: Insights from X-ray absorption spectroscopy analysis and modelling.

Pyrite (FeS) often accommodates elevated concentrations of platinum-group elements in ores of magmatic and hydrothermal origin. In order to elucidate the role of pyrite in concentrating Pd, Pd-doped synthetic crystals were studied via X-ray absorption spectroscopy (XAS). Crystals were obtained by salt-flux method in the system saturated with respect to Pd at the temperature of 580 °C and sulphur fugacity of log f (S) = -0.

New technologies in molecular allergodiagnostics.

The article presents the characteristics of the ALEX2 (MacroArrayDX, Wien, Austria). It is designed for simultaneous detection of IgE total and specific IgE-aB to 120 extracts and 180 molecules by solid-phase enzyme immunoassay. Extracts and allergen molecules combined with nano-particles are sorbed on a solid-phase substrate, forming a macroscopic multiplex matrix - the immune allergy chip.

Discrimination between Streptococcus pneumoniae and Streptococcus mitis based on sorting of their MALDI mass spectra.

Accurate species-level identification of alpha-hemolytic (viridans) streptococci (VGS) is very important for understanding their pathogenicity and virulence. However, an extremely high level of similarity between VGS within the mitis group (S. pneumoniae, S.
