22. Melt-processing and properties of thermoplastic composites based on ethylene-acrylic acid copolymer reinforced with wood nanocellulose
Abstract : Composites reinforced with cellulose nanofibers (CNF), both modified and unmodified cellulose nanocrystals (CNC) and pulp fibers have been prepared through small-scale and large-scale methods. The composites were produced by water-assisted dispersion mixing, drying and compression moulding on the laboratory scale and by extrusion and injection moulding for the large-scale production.

23. Sensing capability of nanomodified Portland cement composites
Abstract : Sensing cement-based composites refer to composites that have sensing functionality that can measure several physical and chemical parameters. Sensing cement-based composites are fabricated by incorporating some functional fillers, such as conductive fibers (CFs), carbon nanofibers (CNFs), carbon nanotubes (CNTs), and graphene, into conventional concrete.

24. Wood-Based Nanocellulose In Lithium Ion Batteries and Electrochemical Coatings
Abstract : Lithium ion batteries contain diverse functional polymeric materials, e.g. binders and separators. Naturally self-assembled wood cellulose can be disintegrated to nanosized particles with a diversity of morphology by top-down processes, adjusting the manufacturing parameters. READ MORE

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