6. Thermoplastic processing of starch and cellulose-containing polymers
Abstract : Starch and cellulose are two naturally occurring polymers that have the potential to reduce the dependence on fossil resources if used as replacements or as complements to synthetic polymers. There are however some problems associated with the use of these polymers that have to be addressed and solved. READ MORE

7. Development and evaluation of hybrid joining for metals to polymers using friction stir welding
Abstract : Combinations of different materials are increasingly used in the modern engineering structures. The driving forces of this trend are rising fuel costs, global warming, customer demands and strict emission standards. READ MORE

8. 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
