Xiaolin Cai, a visiting PhD researcher in the Soil Chemistry Group in 2018, has published a paper with Laurel ThomasArrigo, Xu Fang, Sylvain Bouchet, Ruben Kretzschmar and Yanshan Cui (University of Chinese Academy of Sciences) in Environmental Science and Technology studying the impact of organic matter on arsenic and iron speciation changes during microbial reduction of arsenic(V)-bearing ferrihydrite.

Kevin Hoffmann has successfully defended his doctoral thesis.

The new Mössbauer spectrometer, bought as part of the ERC IRMIDYN project grant, is central to the team’s planned experiments on iron mineral transformations.

Laurel ThomasArrigo (lead author) has published a paper with Sylvain Bouchet, Ralf Kaegi (EAWAG) and Ruben Kretzschmar, investigating the influence of organic matter composition of ferrihydrite transformations with sulfide. The paper was published in Environmental Science: Nano last week.

Kevin Hoffmann (first author) has published the paper with Iso Christl, Ralf Kaegi (EAWAG) and Ruben Kretzschmar, investigating cadmium sulfide nanoparticle growth and stability. The work was published in Environmental Science: Nano.

Natacha Van Groeningen has successfully defended her PhD thesis.

This year, the annual Soil Chemistry hiking event took place as a day trip to the Pizol region

Building on the field trip in the summer of 2019, a team from Soil Chemistry returned to Northern Germany to sample the sediments of the Wadden Sea and Elbe estuary.

A team of researchers from around the world, including Ruben Kretzschmar from Soil Chemistry, have used a combination of spectroscopy techniques to study the study the source of phosphorus along a climatic gradient in Hawaii.

Laurel, along with MSc students Sophie and Tabea, returned to Iceland for another round of soil sampling and field experiments.
