Associate Professor; Chemistry and Chemical Engineering, Applied Surface Chemistry
Anna teaches in the course Chemistry for Engineers (KTK-111) together with Kasper Moth-Poulsen. This course is aimed to transfer the basic knowledge of inorganic, organic, and physical chemistry. The course content is based on the book ”Chemsitry3” by Burrows, Holman, Parsons, Pilling, and Price (2nd Edition).
Anna has also held guest lectures for the course Energy Related Materials (TIF-260), given at the department of physics by Christoph Langhammer and Maths Karlsson.

Research areasIONIC LIQUIDS. Ionic liquids are molecular salts with a melting point close to room temperature. They are typically composed of bulky and asymmetric ions including pyrrolidinium, ammonium, or imidazolium cations, and triflate, sulfonate, or imide anions. Ionic liquids are characterized by a high ionic density, a relatively low viscosity, a high ionic conductivity, and good thermal and chemical stabilities, and are therefore emerging materials for use in electrochemical devices like fuel cells, batteries, and solar cells. Protic ionic liquids represent a subclass that by virtue of having a protic group provide extended H-bonded networks and hypothetically exchangeable protons. A debated question in this field is to what extent the Grotthuss mechanism of proton motion contributes to the overall charge transport.PHYSICO–CHEMICAL PROPERTIES. The ionic liquid properties that I aim to investigate are primarily the mobility of the individual ions (which we probe by conductivity and self-diffusion measurements by NMR spectroscopy), the phase behavior (DSC), the nature of intermolecular interactions (probed by vibrational and NMR spectroscopy), and nano-structuration (SAXS). I am also interested in understanding how these properties change upon addition of a second component such as water or another amphoteric molecule.
