Structural characterization

Advanced depicting techniques and analysing tools for bio-based materials

RISE PFI has developed and applied advanced depicting techniques and analysing tools for 2D and 3D characterisation of a range of bio-based materials, including nanocellulose, biochar, fibre, paper and composite structures. Our characterization methods will facilitate improvements of the final products and a broader understanding of their properties.
