18. Polyelectrolyte Complexes : Their Characterization and use for Modification of Wood Fibre Surfaces
Sammanfattning : For economical reasons filler particles and less expensive fibre raw materials are more frequently used in papermaking. This influences the mechanical properties of the formed papers in a negative way and it is therefore necessary to add strength-enhancing agents to the papermaking furnish. LÄS MER
19. Aspects on Strenght Delivery and Higher Utilisation of the Strength Potential of Kraft Pulp Fibres
Sammanfattning : Studies on strength delivery and related fields have so far concentrated on finding the locations in the mill where fibres are damaged and what the damages consist of. However, fibres will invariably encounter mechanical stresses along the fibreline and in this thesis a new concept is introduced; the vulnerability of fibres to mechanical treatment. LÄS MER
20. Ionic Liquid Lubricants for Space Applications
Sammanfattning : Lubrication is critical to the efficient and reliable operation of machine elements such as gears, bearings, or any other moving mechanical assembly (MMA). On Earth, machine designers are accustomed to the access of a wide range of liquid lubricants that enable predictable and reliable long-term operations of high performance MMA. LÄS MER
