1. Mechanical Pulp-Based Nanocellulose : Processing and applications relating to paper and paperboard, composite films, and foams
Abstract : This thesis deals with processing of nanocellulose originating from pulps, with focus on mechanical pulp fibres and fines fractions. The nanocellulose materials produced within this research project were tested for different purposes ranging from strength additives in paper and paperboard products, via composite films to foam materials.

2. Microfibrillated cellulose: Energy-efficient preparation techniques and applications in paper
Abstract : This work describes three alternative processes for producing microfibrillated cellulose (MFC; also referred to as cellulose nanofibrils, CNF) in which bleached pulp fibres are first pretreated and then homogenized using a high-pressure homogenizer. In one process, fibre cell wall delamination was facilitated by a combined enzymatic and mechanical pretreatment. READ MORE

4. Colloidal interactions and orientation of nanocellulose particles
Abstract : Nanoparticles are very interesting building blocks. Their large surface-to-bulk ratio gives them different properties from those of larger particles. Controlling their assembly can greatly affect macroscopic material properties. READ MORE

5. 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
