“Effects of organic matter–goethite interactions on reactive transport of nalidixic acid: Column study and modeling” by the research group of JF Boily and Khalil Hanna (Rennes Institute of Chemical Sciences) is now published in Environmental Research
Using an AFM tip sensitive to water, we tracked the spatial distributions of water films on minerals. We thank the Environmental Molecular Science Laboratory of Pacific Northwest National Laboratory for access to its facilities through a User grant.

Using vibrational spectroscopy and simulations we resolved the enigmatic surface chemistry of ferrihydrite. Three ways to learn more about our work:

In a collaboration between the JF Boily group and the Allan Bertram group of UBC, we show that K+ is the key ion driving ice nucleation on K-feldspar, an important part of atmospheric mineral dust. Read the paper here:

Emma Westling, Lisa Bryggman and Niklas Viklund from Nolaskolan in Örnsköldsvik brought in soil samples for Cesium-137 analysis. Many thanks to Peder Arvidsson from the University Hospital of Umeå (Center for medical technique and radiation physics) for providing access to his laboratory and hosting the students.
