6. Polymer-coated paper and board - Role of substrate, polymer characteristics and additives
Sammanfattning : The surface roughness of paper or board has a significant influence on the homogeneity of an applied polymer film, and this thesis discusses how it may be improved by a surface treatment, e.g. high-temperature calendering or precoating. LÄS MER
7. Effects of Flow Structure on Particle Separation in Dissolved Air Flotation
Sammanfattning : Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge.

8. Fuel retention and fuel removal from first wall components in tokamaks
Sammanfattning : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for a steady-state operation of a fusion reactor, e.g. ITER. These topics have been explored in the on-going Ph. LÄS MER
9. A Study of the Adhesion Strength of Plasma Sprayed Coatings
Sammanfattning : Surface preparation prior to thermal spraying is a key factor in ensuring a good adhesion of the coating onto the part to be coated. Surface pre-treatment conditions and methods have mainly been developed experimentally and have changed little over the years. LÄS MER
