Iron uptake in Tomato roots from Fe 57 isotope metallic particles

Uptake of Fe from metallic Fe particles composed of pure Fe 57 isotope will be determined by uXRF and uXANES. The use of this single isotope metallic particles will allow to trace the uptake using mossbauer spectroscopy, however the potential chemical trasnformations will remain unresolved, for this purpose the spatial distribution and speciation will be studied at Id21 under cryogenic conditions.
