Decreasing heat transfer through better insulation is essential to improve the energy efficiency of buildings. We develop thermally insulating materials based on renewable or widely abundant raw materials with superinsulating properties and investigate fundamental aspects of heat transfer including phonon scattering and moisture-dependence. Colloidal processing and assembly of biobased nanoparticles into nanostructured materials with useful properties is another important and closely related area of interest where the fundamental activities aim to generate a better understanding of the molecular or mesoscopic assembly mechanisms by in situ studies.
