- Reactions at mineral surfaces have shaped Earth’s ever-changing environments throughout geological times. They are of central interest for Atmospheric Chemistry, Biogeochemistry, Environmental Chemistry, Inorganic Chemistry, Technology, as well as in the study of Space Chemistry.
My research activities are chiefly focused on geochemical reactions at mineral surfaces, and connect scales of molecules, single mineral particles, to single macroscopic crystals. Examples of interest include thin water and ice films, ice nucleation & growth, interfacial electrochemistry.
Our approach is multidisciplinary, and we routinely blend experiment with theory. Main experimental approaches include vibrational (FTIR, Raman, Sum Frequency Generation) and X-ray photoelectron spectroscopy. Electrochemical methods include Electrochemical Impedance Spectroscopy (EIS) and Scanning Electrochemical Microscopy (SECM). Interpretations of laboratory observations are always assisted by molecular simulations (Molecular Dynamics, Density Functional Theory) of representative systems. Reaction mechanisms are often packaged into thermodynamic/kinetic models that can be used to predict atmospheric and geochemical processes.
The Swedish Research Council is currently supporting out project “Rust in Ice” (2021-2024)
We are also still very active in water film research from our previous Swedish Research Council project “Chemistry Within the Confines of Water Films” (2017-2020)
Some projects under way:
- Photocatalytic and mineralogical transformation within thin water films (Tan Luong, Ph.D. student)
- Fate of antibiotics in nature with Khalil Hanna, Funded by CNRS until 2027
- Mn-carbonate and oxide electrochemistry (Lorenden Hysenaj, Erasmus Plus exchange Ph.D. Student)
- Atmospheric ice nucleation (in collaboration with Allan Bertram, University of British Columbia)
