A Boily lab collaboration with Khalil Hanna (Rennes Institute of Chemical Sciences):
Based on a plethora of experiments and advanced geochemical analysis techniques, Hussein Kanbar in the Holmboe group (Department of Chemistry/UMU), in a collaboration with PhD student Fredrik Olajos and Professor Göran Englund from the Department of Ecology and Environmental Sciences/UMU, has published a paper in the Journal of Soils and Sediments, detailing the mineral and geochemical characteristics of Holocene lake sediments from the Hotagen lake in west Sweden (Jämtland).

Kanbar, H.J., Tran Le, T., Olajos, F. et al. Tracking mineral and geochemical characteristics of Holocene lake sediments: the case of Hotagen, west-central Sweden. J Soils Sediments (2021). https://doi.org/10.1007/s11368-021-03012-y
Our planet has more organic carbon in its fragile soil layers than all the carbon on land and atmosphere combined. The Holmboe group is now hiring a PhD student (4 year minimum) and offering one postdoc fellowship (2 years) for two separate but similar projects focusing on the molecular interactions between natural organic molecules and mineral surfaces.
In order to focus on the molecular scale, the research will utilize various experimental methods and molecular dynamics simulations (extracting for instance free energy profiles as shown below), and why not also virtual reality!

This is the first paper from Merve Yesilbas‘ VR- and NASA-supported work with Janice Bishop at the SETI institute.

Using soil analogues, the group showed how cryosalts can trigger landslides on Mars. This suggests the martian environment is still dynamic and active today, which is important for future human exploration on Mars. A portion of the experimental work was done in JF Boily’s laboratory.

“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
Hussein Kanbar and Michael Holmboe has collaborated with EMG/UMU Prof. Göran Englund and PhD student Fredrik Olajos, on the faith of (ancient)DNA adsorbed onto minerals in 10,000 y old Swedish lake sediments. Their first publication is now available online at: doi.org/10.1016/j.apgeochem.2020.104728.
