Why do some product phases form preferentially to others during iron mineral transformation in soil? A new paper, published in Environmnetal Science & Technology by Luiza Notini (ETH Soil Chemistry), Laurel ThomasArrigo (ETH Soil Chemistry), Ralf Kaegi (EAWAG) and Ruben Kretzschmar (ETH Soil Chemistry), demonstrates that products of Fe(II)-catalysed transformation of ferrihydrite depend on the pre-existing mineralogy of the system.

Congratulations to Xu Fang, who yesterday defended his doctoral thesis.

Members of the ERC IRMIDYN team have returned to field sites along the Elbe estuary, northern Germany, to conduct a new round of field experiments.

The annual Soil Chemistry hiking excursion was a two-day event this year, hiking from St Jakob in Uri to Engelberg, and staying at the Bannalpsee.
