I will clearly vote for vivianite - it has the most beautiful rosette crystal structure. It also changes color upon oxidation from white to blue, green or even pink depending on other cations besides Fe in the crystal structure.

The Wadden Sea team are back in the field to sample the experiments we installed in August. The weather is a little challenging but so far we’re still happy to be back in the Watt!

We are excited to share the first data from our Raman spectrometer in this new iron paper ⬇️⬇️

The properties of soil can control the rates and products of mineral transformation. Read how ferrihydrite behaved in five flooded rice paddy soils in the recent paper published #ESPI by ETH Soil Chemistry: ➡ bit.ly/3S3p9IR

Congratulations Angelia!

Some exciting opportunities here ⬇️⬇️ please RT!

We are looking for a postdoc in Microbial Biogeochemistry to join our group @UNIL @UNIL_FGSE. SNSF-funded project on microbe-mineral interactions, climate change, soils. Lot's of imaging and omics. Start in Feb 2023, or asap. #postdocjobs #phdchat #phdone #phdposition. Info👇

So happy to have implemented the ETH help desk! I previously struggled a lot with mental health during my research and would’ve loved to have something like this at my disposal! Thanks @ALloretVillas for undertaking this initiative 🎉🥰

🚨 Just published 🚨- a new study from Laurel ThomasArrigo and Ruben investigating how redox cycling in Icelandic soils influences Fe mineralogy and the mobility of organic carbon: sciencedirect.com/science/articl…

Interested in Iceland? Iron? Carbon? Colloids? Redox? Check out our latest paper!👇

Happy World Soil Day from all at D-USYS@ETH! youtu.be/7-YMheTIPJo

We are going to really miss Laurel after 10 years with us! The group wishes you all the best and are excited for future collaborations

Yesterday, we finally released our outreach film about our ERC-funded #IRMIDYN project, produced together with @markustischner. If you want to see what we ETH Soil Chemistry are doing in the mud, watch it here: youtu.be/XFWnumTda5s?si… For more information, visit soilchem.ethz.ch/IRMIDYN.html

Check out our new ES&T paper reporting results of our field experiment in Thailand, looking at iron mineral transformations in a rice paddy soil and the interactions with phosphate.

EU Research, a quarterly magazine for the dissemination of scientific research in Europe, has featured the ERC IRMIDYN project in its latest edition. Read the article here: issuu.com/euresearcher/d…

Our film "Rust in soils..." is at Braga Science Film Fest this week! It will be available online for 24 hours on Thursday, November 21. Register for free to watch and vote for the Audience Award. bragasciencefilmfest.com
