11. Modification of Paper into Conductive Substrate for Electronic Functions : Deposition, Characterization and Demonstration
Sammanfattning : The thesis investigates the modification of paper into an ion- and electron-conductive material, and as a renewable material for electronic device. The study stretches from investigating the interaction between the cellulosic materials and the conducting polymer to demonstrating the performance of the conductive paper by printing the electronic structure on the surface of the conductive paper.

12. On Heat and Paper : From Hot Pressing to Impulse Technology
Sammanfattning : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. LÄS MER
13. Through-Drying of Tissue Paper - Experiments and Modelling
Sammanfattning : In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). LÄS MER
14. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation
Sammanfattning : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. LÄS MER
15. Antimicrobial materials from cellulose using environmentally friendly techniques
Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.
