Lars Evenäs
Lars Evenäs’ research group has a focus on characterization methodology and materials development in the field of surface and colloid chemistry. The characterization is often based on the application of NMR spectroscopy, ranging from solid-state (e.g. molecular linearity in fibers) and diffusometry (e.g. molecular association in solution) to high-resolution methods (e.g. quantification of multi-functionalized polymers). From a materials perspective, molecular and supramolecular properties of biomass-based materials is one of the main interests where cellulose is the central polymer. Another focus is formulation and physical properties of core-shell particles in order to achieve controlled release of active substances from coatings or fibrillar materials.
