Reactions of aqueous Fe(II) with Fe and Mn oxides influence heavy metal mobility, transformation of trace organics, and important elemental cycles as Fe precipitates form or dissolve, and as electrons move between aqueous and solid phases. Our objective was to characterize reactions of Fe(II) with important metal oxides, using a suite of complementary tools to investigate the extent and underly...

There are some reports in ancient medicinal literature that aqueous extracts of the leaves of Teucrium polium show analgesic effects. This prompted us to investigate the analgesic effect of the leaves of the plant using Tail-Flick and Fomalin tests. For this purpose, male NMRI rats weighing 220-260 g were used in all experiments. The aqueous extract of the plant was injected intraperitoneally a...

The chemical compositions of the aqueous phases in alkali-activated slag (AAS) paste and Portland cement (PC) were determined up to 28 d with aim obtaining a better understanding stability hydration products two binder systems. saturation levels respect PC AAS obtained by thermodynamic modelling. main findings this study were: effective index for portlandite system was always below zero sulfate...
