1. Materials Design for Paper Electrodes : A Papermaking Perspective on Electrode Fabrication
Sammanfattning : The electrification and digitalization of our society has propelled the demand for energy storage solutions. High-end technologies have been developed to satisfy the requirements of demanding applications, such as electromobility and portable consumer electronics, which also increasingly find markets for less demanding applications.

2. Vacuum Dewatering of Cellulosic Materials : New insights into transport phenomena in the papermaking process
Sammanfattning : Working towards sustainable development within the forest industry, the dewatering of pulp and paper must be fully understood along with the dewatering of other cellulose-based materials. Huge amounts of energy are used during paper manufacturing so there is a potential for making the processes more energy-efficient. LÄS MER
3. Papper och lump : studier av kontinuitet och förändring i nordisk pappersindustri från 1600-tal till 1900-tal
Sammanfattning : . This thesis consists of an introduction and four previously published articles. The joint empirical focus is papermaking based on textile rags as fibre raw material. Furthermore the physical environment is central in the studies. LÄS MER
4. Simulations of the Dynamics of Fibre Suspension Flows
Sammanfattning : A new model for simulating non-Brownian flexible fibres suspended in a Newtonian fluid has been developed. Special attention has been given to include realistic flow conditions found in the industrial papermaking process in the key features of the model; it is the intention of the author to employ the model in simulations of the forming section of the paper machine in future studies.

5. Near wall fibre orientation in flowing suspensions
Sammanfattning : This thesis deals with fibre orientation in wall-bounded shear flows. The primary application in mind is papermaking. The study is mainly experimental,but is complemented with theoretical considerations.The main part of the thesis concerns the orientation of slowly settlingfibres in a wall-bounded viscous shear flow.
