2. 21. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production

   Author : Britta Andres; Håkan Olin; Christina Dahlström; Jonas Örtegren; Renyun Zhang; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electric Double-Layer Capacitor; Graphite; Cellulose Nanofibers; Large-Scale; Mass Balancing; Metal-Free;

   Abstract : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. READ MORE

   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

5. 23. Biodegradable nanocomposite films based on amylopectin and chitosan

   Author : David Nordqvist; Mikael Hedenqvist; Lars Berglund; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

   Abstract : The use of disposable material is rapidly increasing, today the absolute majority of the material used for these application, i.e. food packages, are oil-based plastics such as polyethylene and polypropylene. Therefore it is of great importance to find alternative biodegradable materials made from renewable resources for this huge growing market. READ MORE

6. 24. Bio-based barriers from wood hydrolysates : A pilot-scale approach

   Author : Soheil Saadatmand; Ulrica Edlund; Youssef Habibi; KTH; []
