11. Bio-based barriers from wood hydrolysates : A pilot-scale approach
Abstract : Wood hydrolysates (WHs) are liquids extracted from the hydrothermal treatment of wood. They exist as the byproduct of forestry industries such as the dissolving pulp and fiberboard industries. WHs are hemicellulose-based with a large share of lignin in the chemical composition. READ MORE

12. Design of new bioresourcepackaging from wood hydrolysates
Abstract : Hemicelluloses are a large group of polysaccharides that have recently attracted considerable attention in many industrial fields due to their abundance and renewability. They are non-edible and possess very good oxygen-barrier properties. READ MORE

13. Innate Confinement Effects in PCL Oligomers as a Route to Confined Space Crystallisation
Abstract : In this work, an in-depth analysis of crystalline characteristics has been performed for a unique set of strictly monodisperse poly-ε-caprolactone (PCL) oligomers. The molecules have different sets of end groups with various degrees of bulkiness and hydrogen bonding potential, affecting their aptitude to pack in ordered crystal structures. READ MORE

14. Polymer extraction and utilization of brown algal biomass
Abstract : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. READ MORE

15. Biopolymers and materials from rapeseed straw biorefining
Abstract : Rapeseed straw was fractionated through a hydrothermal process into its hemicellulose, lignin and cellulose components. In the first step, hemicellulose-rich fractions were extracted. Xylan-rich fractions with high molecular weight, 30,000 – 50,000 g/mol, were obtained at 110 °C and 1.5 M NaOH. READ MORE
