21. Porous materials based on nanopolysaccharides for medical applications: Effect of crosslinking on pore structure and mechanical performance
Abstract : The objective of this work was to develop nanochitin- and nanocellulose-based crosslinked porous nanostructured materials for wound dressing and cartilage repair with suitable porosity and mechanical properties to facilitate cell growth. In the first part of the work (papers I-III), chitosan-based nanocomposites loaded with a high concentration (50 wt%) of chitin nanocrystals (ChNC) and cellulose nanocrystals (CNC) were prepared via electrospinning for use as wound dressing materials.

25. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials
Abstract : Bio-based resource utilization in different forms has been driven by societal, industrial and academic research interests towards the development of “green”, sustainable materials from renewable sources. Within this context, exploiting biomass from different industrial residues is further advantageous from an environmental and economic point of view, leading to minimization of residues by means of waste treatment and to the development of high-addedvalue- products.
