PhD position available in the Holmboe group!

Many countries such as Sweden rely on nuclear power to meet their energy needs.  As a result, various types of deep geologic repository concepts for the disposal of nuclear waste are being planned worldwide. The goal of this PhD project is to study radiation-induced chemistry at the molecular level in the context of nuclear waste disposal, using advanced theoretical and experimental techniques, such as molecular simulations, gamma-radiation and X-ray synchrotron-based methods. This 4-year PhD project is funded by the Swedish Radiation Authority (SSM), and builds upon prior research in the Holmboe group in collaboration with Prof. Mats Jonsson, Applied Phys. Chem, KTH, Sweden.

New paper on methylmercury bioavailability!

Top right: Principles for DOM-thiol controlled uptake of MeHg via thermodynamically or kinetically controlled mechanisms. Bottom right: Large, systematic decrease in DOM-thiols, and thereby increase in MeHg uptake across the terrestrial-marine aquatic continuum.

Research in Björn’s group show how the availability of methylmercury for incorporation at the base of the aquatic food web (by phytoplankton cellular uptake) is controlled by the concentration of thiol functional groups in dissolved organic matter. The research further shows how the concentration of DOM-thiols systematically decreases across the terrestrial-marine aquatic continuum.

Congratulations Sébastien!

Sébastien Le Crom (Kempe Postdoc in Boily group) is beginning a “Maître de Conférence” position at Institut Mines-Télécom Nantes (France) in September 2023.
